Abstract Introduction: Even though only a few species are considered to be dangerous, pests or vectors, the majority of invertebrates produce a feeling of aversion in humans. This has contributed to the delay in the development of ethical considerations as regards this group in contrast with vertebrates, with the exception of cephalopods. Objective: In the present study, we provide an overview of the current situation on animal ethics and welfare in order to contribute to the development of a framework for ensuring invertebrate welfare. Methods: Today, animal welfare is multidisciplinary in nature to a very high degree as it includes ethology, physiology, pathology, biochemistry, genetics, immunology, nutrition, cognitive-neural, veterinary medicine, and ethics. Animal welfare is a complex concept, difficult to achieve successfully from one perspective. Results: As a consequence, we propose to include the five domains (nutrition, environment, health, behaviour and mental state) along with the three conceptions (basic health and functioning, affective state and natural living), as well as the 5R Principle (Replace, Reduction, Refinement, Respect and Responsibility) in seeking to achieve a comprehensive welfare state. Conclusions: We consider that in both research and animal production, the individual and collective ethical concerns coexist and, in fact, the main moral concern to account for is the collective one and that, within that collective view, the individual moral concern should be applied with responsibility and respect for the individual. Finally, we propose a practical example of invertebrate welfare production in sea urchin aquaculture with the aim of including animal production of invertebrates in this important discussion.

Resumen Introducción: Aunque sólo unas pocas especies son consideradas peligrosas, plagas o vectores, la mayoría de los invertebrados producen un sentimiento de aversión en el ser humano. Esto ha contribuido al retraso en el desarrollo de consideraciones éticas respecto a este grupo en comparación con los vertebrados, a excepción de los cefalópodos. Objetivo: En el presente trabajo, proporcionamos una visión general de la situación actual en materia de ética y bienestar animal con el fin de contribuir al desarrollo de un marco para garantizar el bienestar de los invertebrados. Métodos: Hoy en día, el bienestar animal es de naturaleza multidisciplinaria en un grado muy alto, ya que incluye etología, fisiología, patología, bioquímica, genética, inmunología, nutrición, cognitivo-neural, medicina veterinaria y ética. El bienestar animal es un concepto complejo, difícil de lograr con éxito desde una sola perspectiva. Resultados: Como consecuencia, proponemos incluir los cinco dominios (nutrición, ambiente, salud, comportamiento y estado mental) junto con las tres concepciones (Salud básica y funcionamiento, estado afectivo y vida natural), así como el Principio 5R (Reemplazar, Reducir, Refinar, Respetar y Responsabilidad) en la búsqueda de alcanzar un estado de bienestar integral. Conclusiones: Consideramos que tanto en la investigación como en la producción animal coexisten las preocupaciones éticas individuales y colectivas y, de hecho, la principal preocupación moral a dar cuenta es la colectiva y que, dentro de esa visión colectiva, se debe aplicar la preocupación moral individual. con responsabilidad y respeto por la persona. Finalmente, proponemos un ejemplo práctico de producción de bienestar de invertebrados en la acuicultura de erizos de mar con el objetivo de incluir la producción animal de invertebrados en esta importante discusión.

Abstract Sustainable forest management requires the integration of better practices for the conservation of biological diversity. Therefore, it is necessary to know the composition and richness of wild communities in sites where different forest management practices are applied. To this end, the fauna of managed forests in the Chignahuapan region of Puebla State was sampled for four years. A total of 112 species were recorded: 13 medium and large mammals, 83 birds, four amphibians and 12 reptiles. The abundances of these observed species were used to calculate the expected richness with the non-parametric Chao1 estimator. The management method with the highest expected richness was the Silvicultural Development Method (MDS) with 113, followed by Successive Cutting (CS) with 97, and the lowest was observed in the Mexican Method for the Management of Irregular Forests (MMOBI) with 71. Sampling completeness ranged from 92 % in amphibians to 99 % in mammals. Sixteen species are in some risk category in the official Mexican standard NOM-059-SEMARNAT-2010, and 25 are endemic to Mexico. Taxonomic lists contain information on conservation status, endemism and relative abundance. Intensive forest management methods, such as MDS, have a richer mammal and bird community than MMOBI and CS but are similar to protected areas. The richness and abundance of amphibians and reptiles, most of them in some risk category, are low, especially in MMOBI and CS, and almost absent in protected areas.

Resumen El manejo forestal sustentable requiere de la integración de mejores prácticas de conservación de la diversidad biológica. Para esto, es necesario conocer la composición y riqueza de las comunidades silvestres en los sitios donde se aplican diferentes prácticas silvícolas. Con esta finalidad, se muestreó durante cuatro años la fauna de bosques productivos de la región de Chignahuapan, Puebla. Se registraron 112 especies: 13 de mamíferos medianos y grandes, 83 de aves, cuatro de anfibios y 12 de reptiles. A partir de la abundancia de estas especies observadas, se determinó la riqueza esperada con el estimador no paramétrico Chao1. El método de manejo con mayor riqueza esperada fue el Método de Desarrollo Silvícola (MDS) con 113, seguido por Cortas Sucesivas (CS) con 97, y la menor se observó en el Método Mexicano de Ordenación de Bosques Irregulares (MMOBI) con 71. La completitud de los muestreos varió del 92 % en anfibios al 99 % en mamíferos. Dieciséis especies se encuentran en alguna categoría de riesgo en la norma oficial mexicana NOM-059-SEMARNAT-2010, y 25 son endémicas de México. Se presentan listas taxonómicas con información sobre la situación de conservación, endemismo y abundancia relativa. Los métodos intensivos de manejo forestal, como MDS, tienen una comunidad de mamíferos y aves más rica que el MMOBI y CS, pero similar a las de áreas bajo protección. La riqueza y abundancia de anfibios y reptiles, la mayoría en alguna categoría de riesgo, son bajas, especialmente en el MMOBI y CS, y casi ausentes en zonas de protección.

Abstract Oestrus ovis larvae are obligate parasites of vertebrates and cause cavitary myiasis (oestrosis) in sheep and goats. It is also reported as a zoonosis causing ophthalmomyiasis and nasopharyngeal myiasis. Despite being relatively common in Brazil, epidemiological studies on O. ovis are scarce. Considering that the infestation is influenced by the climate and biomes of the studied region, we aimed to investigate the seasonal prevalence of O. ovis among slaughtered sheep in the northern region of the state of Mato Grosso, Brazil. The heads of sheep (n=697) slaughtered at a slaughterhouse in the municipality of Terra Nova do Norte (November 2011 to November 2013) were collected to count, catalog, and identify the larvae found in the upper respiratory tract. Overall, 45.77% (319/697) of the animals were infested with 2,412 recovered larvae, 96.89% (2,337/2,412) of which were identified at the species level as O. ovis. Seasonal variations in prevalence ranged from 41% (spring) to 56% (summer); however, no correlation was observed between prevalence and season, mean humidity, or temperature. In conclusion, parasitism by O. ovis in sheep in the studied area, occurs year-round, considering the occurrence of larvae (L1, L2, and L3) throughout the year, probably because of the area's environmental conditions. oestrosis (oestrosis goats Brazil O scarce Grosso n=697 n697 n 697 (n=697 201 2013 count catalog tract Overall 4577 45 77 45.77 319/697 319697 319 (319/697 2412 2 412 2,41 9689 96 89 96.89 2,337/2,412 23372412 337 (2,337/2,412 41 spring (spring 56 summer (summer) however season humidity temperature conclusion area yearround, yearround year round, round year-round L1, L1 L (L1 L2 L3 areas s conditions n=69 n69 69 (n=69 20 457 4 7 45.7 319/69 31969 31 (319/69 241 2,4 968 9 8 96.8 2,337/2,41 2337241 33 (2,337/2,41 5 (summer (L n=6 n6 6 (n=6 45. 319/6 3196 3 (319/6 24 2, 96. 2,337/2,4 233724 (2,337/2,4 n= (n= 319/ (319/ 2,337/2, 23372 (2,337/2, (n (319 2,337/2 2337 (2,337/2 (31 2,337/ 233 (2,337/ (3 2,337 23 (2,337 ( 2,33 (2,33 2,3 (2,3 (2, (2

Resumo As larvas de Oestrus ovis são parasitas obrigatórios de vertebrados e causam miíase cavitária (estrose) em ovinos e caprinos. Também é relatada como uma zoonose que causa oftalmomíase e miíase nasofaríngea. Apesar de relativamente comum no Brasil, os estudos epidemiológicos sobre O. ovis são escassos. Considerando que a infestação é influenciada pelo clima e biomas da região estudada, objetivou-se investigar a prevalência sazonal de O. ovis entre ovinos abatidos na região norte do estado de Mato Grosso, Brasil. Foram coletadas cabeças de ovinos (n=697) abatidos em frigorífico do município de Terra Nova do Norte (novembro de 2011 a novembro de 2013) para contagem, catalogação e identificação das larvas encontradas no trato respiratório superior. No geral, 45,77% (319/697) dos animais estavam infestados com 2.412 larvas recuperadas, das quais 96,89% (2.337/2.412) foram identificadas em nível de espécie como O. ovis. As variações sazonais na prevalência variaram de 41% (primavera) a 56% (verão); no entanto, não foi observada correlação entre prevalência e estação do ano, umidade média ou temperatura. Conclui-se que o parasitismo por O. ovis em ovinos na área estudada ocorre durante todo o ano, considerando a ocorrência de larvas (L1, L2 e L3) ao longo do ano, provavelmente devido às condições ambientais da área. estrose (estrose caprinos nasofaríngea Brasil O escassos objetivouse objetivou se Grosso n=697 n697 n 697 (n=697 201 2013 contagem superior geral 4577 45 77 45,77 319/697 319697 319 (319/697 2412 2 412 2.41 recuperadas 9689 96 89 96,89 2.337/2.412 23372412 337 (2.337/2.412 41 primavera (primavera 56 verão (verão) entanto ano temperatura Concluise Conclui L1, L1 L (L1 L3 n=69 n69 69 (n=69 20 457 4 7 45,7 319/69 31969 31 (319/69 241 2.4 968 9 8 96,8 2.337/2.41 2337241 33 (2.337/2.41 5 (verão (L n=6 n6 6 (n=6 45, 319/6 3196 3 (319/6 24 2. 96, 2.337/2.4 233724 (2.337/2.4 n= (n= 319/ (319/ 2.337/2. 23372 (2.337/2.

Abstract: This paper presents the zooarchaeological and technological information from P 35 shell midden, located in Punta Entrada, Santa Cruz River mouth (Argentina). The zooarchaeological assemblage, with a large representation of individuals of different sexes and ages of Arctocephalus australis and Otaria flavescens, reinforces the previous statements about the exploitation of otariid settlements in the locality. Other taxa, such as cetaceans, Culpeo fox, guanaco, Imperial shag, Darwin rhea and Upland goose, are represented in smaller numbers and were opportunistically exploited. Bone technology was mostly made at the site with bones from the fauna represented in the zooarchaeological assemblage, except for a sawn huemul antler. Lithic and bone technology includes components that can be related to weaponry systems which are consistent with the preys identified in the zooarchaeological assemblage. Based on the evidence from P 35, Punta Entrada appears as a recurrently visited coastal sector, which would have served not only as a place for the planned supply of highly productive animal resources (otariids), but also allow access to those resources that were opportunistically obtained but with high potential as inputs for human subsistence.

Resumen: Se presenta la información zooarqueológica y la tecnología ósea del conchero P 35, ubicado en Punta Entrada, desembocadura del río Santa Cruz (Argentina). El conjunto zooarqueológico, con gran representación de restos de individuos de diferentes sexos y edades de Arctocephalus australis y de Otaria flavescens, refuerza las afirmaciones previas sobre la explotación de asentamientos de otáridos en la localidad. Otros taxones, como los cetáceos, el zorro colorado, el guanaco, los cormoranes imperiales, el ñandú y el cauquén común, están representados en menor cantidad y fueron aprovechados de manera oportunista. La tecnología ósea fue confeccionada en el lugar, con huesos de la fauna registrada en el conjunto zooarqueológico, con excepción de un asta de huemul aserrada. El conjunto de instrumentos óseos y líticos incluye piezas vinculadas con sistemas de armas apropiados para la caza de las especies registradas en el depósito. A partir de la evidencia de P 35, Punta Entrada aparece como un sector costero recurrentemente visitado, que habría funcionado no sólo como lugar de aprovisionamiento planificado de recursos animales muy productivos y con localizaciones conocidas (los otáridos), sino que también brindaba posibilidades de acceso a aquéllos obtenidos de manera oportunista, pero con alto potencial como insumos para la subsistencia humana.

Abstract Many species of Bromeliaceae store water among their leaves creating microhabitats for several biological groups. Using bromeliads in enrichment of reforestation offers an opportunity to understand the occupation of tank habitat, and the impacts of these plants in increasing biodiversity. We translocated 20 rescued individuals of tank-bromeliad Hohenbergia ramageana to enrich a reforested area in Atlantic Forest. Then, we recorded the visiting dynamics of animals in the tank habitat of H. ramageana. Ten orders of vertebrates and invertebrates visited nine terrestrial and eight epiphyte tank-habitats just one month after the translocation. Richness and composition were similar between epiphyte and terrestrial translocations. We found that precipitation explained a significant proportion of variation of the number of visited plants and richness of animal orders. Our results confirm the importance of using tank-bromeliads in reforested ecosystems and bring novelty that reintroduced bromeliads in alternative habitats also play the same role for animal groups as in their original habitat. This knowledge will orientate future plans of conservation of bromeliads and of ecosystem restoration. biodiversity 2 tankbromeliad bromeliad Forest Then H tankhabitats translocation translocations tankbromeliads restoration

Resumo Muitas espécies de Bromeliaceae armazenam água entre suas folhas criando microhabitats para diversos grupos biológicos. O uso de bromélias no enriquecimento de reflorestamentos oferece uma oportunidade para entender a ocupação do habitat tanque e os impactos dessas plantas no aumento da biodiversidade. Foram translocados 20 indivíduos resgatados da bromélia-tanque Hohenbergia ramageana para enriquecimento de uma área reflorestada de Mata Atlântica. Em seguida, foi gravada a dinâmica de visitação de animais no habitat tanque de H. ramageana. Dez ordens de vertebrados e invertebrados visitaram nove habitats tanques terrícolas e oito epífitos apenas um mês após a translocação. A riqueza e a composição foram semelhantes entre as translocações epífitas e terrícolas. Descobrimos que a precipitação explicou uma proporção significativa de variação do número de plantas visitadas e da riqueza de ordens de animais. Nossos resultados confirmam a importância do uso de bromélias-tanque em ecossistemas reflorestados e trazem novas evidências de que as bromélias reintroduzidas em habitats alternativos também desempenham o mesmo papel para grupos de animais que em seu habitat original. Esse conhecimento orientará planos futuros de conservação de bromélias e de restauração de ecossistemas. biológicos biodiversidade 2 broméliatanque bromélia Atlântica seguida H translocação broméliastanque original

Abstract The aim of this study was to record Centrorhynchus sp. associated with the exotic species Aquarana catesbeiana (bullfrog) in southern Brazil and to present a checklist of vertebrate hosts in South America. Twenty-nine adults and juveniles of A. catesbeiana were collected in Capão do Leão, state of Rio Grande do Sul, Brazil, between October 2019 and December 2020. We found 275 specimens of Centrorhynchus sp. cystacanths in the stomach musculature and coelomic cavity of 55.1% of hosts (16). There was no significant differences in the prevalence and mean intensity of infection with cystacanths when compared males and females of A. catesbeiana. The prevalence was significantly higher in adults than in juveniles. The checklist presents 106 species of vertebrate hosts and 14 taxa of Centrorhynchus recorded in nine South American countries. Avian were the main definitive hosts of Centrorhynchus spp. and snakes Dipsadidae, anurans Hylidae and Leptodactylidae the main paratenic hosts in South America. This is the first record of Centrorhynchus cystacanths in A. catesbeiana in the South America. The study provides tools to help understand the parasitic relationships between species of Centrorhynchus and A. catesbeiana and other hosts in areas where bullfrog have been introduced. sp (bullfrog America Twentynine Twenty A Leão Sul 201 2020 27 551 55 1 55.1 16. 16 .

Abstract Because of the exacerbated use of pesticides and their mixtures, and the difficulty of evaluating their toxicity, it is necessary to identify sensitive tools for the early detection of potential environmental risks related to the use of these chemicals. Our objective was therefore to evaluate the effects of these chemicals using a rapid 24 h toxicity test in zebrafish embryos. After exposure of individual and mixtures of the pesticides carbendazim (carb), fipronil (fipr), and sulfentrazone (sulf), the lethality and sublethally at 24 hpf, the effects of the mixtures on epiboly and on coagulation of the embryos at 8 hpf were evaluated. This model can be extrapolated to several vertebrate groups, including humans. All three pesticides were toxic in both exposure periods, at 24 hpf, all concentrations used affected the embryos, with lethal and sublethal effects occurring. At 8 hpf, epiboly analysis indicated that the mixtures did not potentiate the effects compared to the pesticides alone, being toxic in the order: carb > sulf > fipr > fipr + sulf > carb + sulf > carb + fipr + sulf > carb + fipr + sulf > carb + fipr. We conclude that the most toxic pesticide was sulfentrazone, since it was highly toxic to embryonic development at 24 hpf and caused both delayed epiboly and high percent clotting at 8 hpf. Thus, we see that the rapid toxicity test was effective in assessing the toxicity of pesticides and was sensitive in assessing the effects of pesticides at low concentrations. 2 carb, , (carb) fipr, (fipr) sulf, (sulf) evaluated groups humans periods occurring alone order Thus (carb (fipr (sulf

Resumo Devido ao uso exacerbado dos agrotóxicos e suas misturas e à dificuldade de avaliação de toxicidade, faz-se necessária a busca de ferramentas sensíveis para detectar precocemente potenciais riscos ambientais relacionados ao uso desses produtos químicos. Portanto, nosso objetivo foi avaliar os efeitos desses produtos usando um teste rápido de toxicidade de 24 h em embriões de zebrafish. Após exposição dos pesticidas carbendazim (carb), fipronil (fipr) e sulfentrazona (sulf) isolados e misturados, foi avaliado a letalidade e subletalidade em 24 hpf, e os efeitos na epibolia e coagulação das misturas nos embriões em 8 hpf, com este, essa metodologia pode ser extrapolada para diversos grupos de vertebrados, inclusive humanos. Os três pesticidas foram tóxicos em ambos os períodos de exposição, a 24 hpf, todas as concentrações utilizadas afetaram os embriões, ocorrendo efeitos letais e subletais. Aos 8 hpf, a análise de epibolia indicou que as misturas não potencializaram os efeitos em relação aos agrotóxicos isoladamente, sendo tóxicas na ordem: carb > sulf > fipr > fipr + sulf > carb + sulf > carb + fipr + sulf > carb + fipr + sulf > carb + fipr. Concluímos que o pesticida mais tóxico foi o sulfentrazona, uma vez que foi altamente tóxico para o desenvolvimento embrionário em 24 hpf e causou retardo na epibolia e alto percentual de coagulação em 8 hpf. Assim, vemos que o teste rápido de toxicidade foi eficaz na avaliação da toxicidade dos pesticidas e foi sensível na avaliação dos efeitos destes pesticidas em baixas concentrações. fazse faz se químicos Portanto 2 zebrafish carb, , (carb) (fipr (sulf misturados este vertebrados humanos subletais isoladamente ordem Assim (carb

Resumen: La cacería es una actividad que forma parte del patrimonio biocultural de los mayas de la Península de Yucatán, ya que desde la época prehispánica ha sido parte de su estrategia de uso múltiple de recursos y su cosmovisión. El estudio de los conocimientos y prácticas sobre el empleo de los recursos naturales puede contribuir a aumentar la resiliencia de las comunidades biológicas y humanas ante las perturbaciones. El objetivo de este estudio fue caracterizar el conocimiento biocultural asociado a la cacería tradicional en la comunidad maya de Xul, Yucatán. Se aplicaron 42 cuestionarios mixtos y siete entrevistas semiestructuradas a cazadores locales entre septiembre y diciembre de 2020. Se reportaron 23 especies de vertebrados que se cazan en Xul (16 mamíferos, 6 aves y 1 reptil) y sus usos. Las especies de mayor importancia cultural (IIC) son el venado cabrito (Mazama temama), el jabalí (Pecari tajacu) y el pavo de monte (Meleagris ocellata). La temporada de sequía es la preferida para cazar (71.4 %) y los sitios son la milpa (92.9 %) y el monte alto (83.3 %). Las técnicas que más se practican son la batida (p’uuj; 92.9 %), caminar por el monte (xíimbal ts’on; 73.8 %) y el lampareo (ts’on; 69 %). En Xul existen creencias en elementos y entidades como las virtudes, los Dueños de los animales y los vientos (Ik’). Estos resultados manifiestan la continuidad e importancia de considerar el conocimiento biocultural sobre la cacería con relación al manejo y conservación de la fauna silvestre en comunidades rurales.

Abstract: Hunting is part of the biocultural heritage of the Maya people of the Yucatán Peninsula because it has been part of their strategy of multiple use of resources and their cosmovision since pre-Hispanic times. The study of knowledge and practices on the uses of natural resources can help to improve the resilience of biological and human communities to disturbances. The aim of this study was to characterize the biocultural knowledge associated with traditional hunting in the Mayan community of Xul, Yucatán. From September to December 2020, 42 mixed questionnaires and seven semi-structured interviews were applied to local hunters. It was found that 23 species of vertebrates (35 mammals, 6 birds, and 1 reptile) are hunted in Xul and are used mainly for food. The species with higher cultural importance (IIC) were the red brocket deer (Mazama temama), collared peccary (Pecari tajacu), and ocellated turkey (Meleagris ocellata). The dry season is their favorite season for hunting (71.4 %) and hunters prefer the milpa (92.9 %) and forest (83.3 %) as hunting sites. The most practiced techniques are the “batida” (flushing by hunting teams, p’uuj; 92.9 %), “caminar por el monte” (walking through the woods, xíimbal ts’on; 73.8 %), and “lampareo” (hunting with flashlights, ts’on; 69 %). In Xul there are beliefs such as virtues, the owners of animals and the winds (Ik’). These results show the continuity of biocultural knowledge related to hunting and its importance in the management and conservation of wild fauna in rural communities.

Resumen: Ante el cambio climático, las especies pueden perder representación de su nicho en el biotopo, viéndose afectado el riesgo de extinción. Esta breve revisión de la literatura pretende establecer las bases del estado del conocimiento sobre riesgo de extinción en función al nicho climático. Esto permitirá formular futuros abordajes tales como predicciones de riesgo en base al nicho climático. Según la literatura, la amplitud del nicho y la posición relativa de sus componentes determinan el riesgo de extinción. Esta información puede complementar el conocimiento sobre el riesgo de extinción relacionado a la distribución geográfica. También se puede utilizar para planificar estrategias de conservación específicas para cada situación. Las características de los nichos climáticos pueden interactuar con factores externos (amenazas, competencia) e intrínsecos (área ocupada, dispersión), afectando el riesgo de extinción. Aún persisten vacíos de información sobre los nichos climáticos y limitaciones en sus métodos de estudio. La literatura existente se ha enfocado en vertebrados paleárticos y nichos realizados. Por último, se presenta un caso de estudio que ilustra diferencias entre los nichos climáticos realizados de especies de aves según su riesgo de extinción, mediante la comparación de estadísticas descriptivas. Estas confirman en parte lo que menciona la literatura, pero requieren mejoras para garantizar que proporcionen información veraz. En el futuro, sería interesante explorar estas estadísticas como predictores climáticos para conocer el estado de especies poco conocidas y entender mejor el riesgo de extinción, agregando la dimensión climática a las evaluaciones de riesgo.

Abstract: Species could lose part of their niche representation in the biotope due to climate change, potentially affecting extinction risk. This brief review of the literature aims to establish the basic aspects of our current knowledge concerning extinction risk related to climatic niches. This will enable the formulation of future approaches such as predictions of extinction risk based on the climatic niche. The literature indicates that niche width and relative position of niche components determine extinction risk. This information could complement our knowledge of extinction risk based on geographic distributions. It could also be used to plan specific conservation strategies for each situation. Climatic niche characteristics may interact with external factors (threats and competition) and intrinsic factors (occupied area and dispersal), affecting extinction risk. Information gaps about climatic niches persist as well as limitations of their study methods. Most studies have focused on paleartic vertebrates and realized niches. Finally, a case study is presented in which differences among bird realized climatic niches according to their extinction risk are illustrated by comparing descriptive statistics. These partially confirm what is mentioned in the literature but should be improved to guarantee that they provide accurate information. In the future, it would be interesting to explore these descriptive statistics as climatic predictors of conservation status for data deficient species and to gain a better understanding of extinction risk by adding the climatic dimension to risk evaluations.

Abstract Vertebrate animals used in experimental protocols are recognized as sentient, promoting their consideration within zooethic consideration, their protection in national and international legislation, and their welfare. This has led researchers to resort to other models, such as some invertebrate animals. However, except in particular cases, invertebrates do not have the same legal protection nor welfare provision because they are not recognized as sentient. A review of scientific articles (from 1997 to 2022) was carried out that examined sentience between the Mollusca, Arthropoda and Nematoda, phyla widely used as experimental models. Eighteen articles were found that confirmed a certain degree of sentience in these phyla. Therefore, we propose they should be included in the zooethical consideration. In addition, this text constitutes a first effort to promote the well-being of these individuals used in experimental procedures.

Resumen Los vertebrados usados en protocolos experimentales son reconocidos como sintientes, lo cual favorece su consideración desde la zooética, su protección en la legislación nacional e internacional, así como la salvaguarda de su bienestar. En consecuencia, se ha recurrido a otros modelos in vivo como los animales invertebrados para realizar investigación. Salvo casos particulares, los invertebrados no cuentan con la protección legal ni existe preocupación por su bienestar, en tanto que se les consideraba no sintientes. Por lo tanto, se realizó una revisión de artículos científicos (de 1997 a 2022) para examinar la sintiencia entre los grupos Mollusca, Arthropoda y Nematoda, phyla ampliamente utilizados como modelos experimentales. Se encontraron dieciocho artículos que constataron un cierto grado de sintiencia en estos phyla, por lo que se propone su inclusión en la reflexión zooética. Este texto constituye un primer esfuerzo para procurar el bienestar de estos individuos utilizados en procedimientos experimentales.

Resumen Introducción. Cryptosporidium spp. es un parásito protozoario del grupo de los coccidios, causante de diarreas, trastornos gastroentéricos y respiratorios (baja frecuencia) en diferentes especies de vertebrados a nivel mundial, principalmente en individuos jóvenes. Objetivo. Documentar las características más importantes de virulencia y patogenia del Cryptosporidium spp. así como, la descripción de sus variantes genéticas y su potencial zoonótico. Desarrollo. Existen más de diecinueve especies de Criptosporidium spp., donde se destacan C. parvum (humanos), C. bovis (bovinos), C. suis (porcinos) y C. ubiquitum (aves), debido a su alta capacidad infectiva dada por la diversidad de sus factores de virulencia. El parásito posee afinidad por los enterocitos y genera anomalías en la absorción y funciones secretoras del intestino. La criptosporidiosis varía en función del estado del huésped (edad, nutrición e inmunología), la fuente de contaminación (agua o ingesta), transmisión e higiene. Existen técnicas de diagnóstico, desde pruebas coproscópicas convencionales hasta pruebas de biología molecular. Conclusión. Factores como la variabilidad y los factores de virulencia del Cryptosporidium spp, se consideran mecanismos que favorecen la infección y dispersión del parasito a nivel individual y grupal en humanos y animales domésticos, al igual que la complejidad del ciclo de vida, la resistencia a condiciones ambientales, la capacidad infectiva y la interacción con el huésped consolidan al Cryptosporidium spp. como un agente zoonótico con efectos económicos importantes.

Abstract Introduction. Cryptosporidium spp. is a protozoan parasite belonging to the group of coccidia, causing diarrhea, gastroenteric, and respiratory disorders (less frequently) in different vertebrate species worldwide, primarily in young individuals. Objective. To document the most important virulence and pathogenic characteristics of Cryptosporidium spp., as well as the description of its genetic variants and its zoonotic potential. Development. There are more of 19 species of Cryptosporidium spp., with C. parvum (humans), C. bovis (cattle), C. suis (swine), and C. ubiquitum (birds) being noteworthy due to their high infectivity capacity, given by the diversity of their virulence factors. The parasite has an affinity for enterocytes and causes abnormalities in the intestinal absorption and secretory functions. Cryptosporidiosis varies depending on the host's status (age, nutrition, and immunity), the source of contamination (water or ingestion), transmission, and hygiene. Diagnostic techniques range from conventional coproscopic tests to molecular biology tests. Conclusion. Factors such as the variability and virulence factors of Cryptosporidium spp. are considered mechanisms that favor the infection and spread of the parasite at an individual and group level in humans and domestic animals, as well as the complexity of its life cycle, resistance to environmental conditions, the infective capacity, and host interaction consolidate Cryptosporidium spp. as a zoonotic agent with significant economic effects.

Resumen Introducción: Las vías de comunicación son parte del desarrollo económico y social en todo el mundo. El desarrollo de carreteras causa la fragmentación de ecosistemas naturales, aumentando el riesgo de mortalidad de los animales silvestres por atropellamientos vehiculares. Objetivo: Analizar la tasa de mortalidad de vertebrados silvestres atropellados de acuerdo con la temporada climática y el grado de urbanización en una zona costera del estado de Guerrero, al sur de México. Métodos: Se realizaron 12 recorridos con tres observadores en un vehículo a una velocidad de 30 km/h durante un año (junio de 2021 a mayo de 2022). Los organismos fueron georreferenciados e identificados. Se calculó la tasa de atropellamiento (atropellos/día/kilómetro) de los vertebrados silvestres. Resultados: Se registraron 37 especies de vertebrados silvestres atropellados, de las cuales nueve están en peligro de extinción y siete son endémicas de México. Los mamíferos presentaron la tasa de mortalidad más elevada (0.126 animales atropellados/día/km). No hubo diferencias en la tasa de mortalidad entre temporadas. Se detectaron 11 puntos calientes (hotspots) de atropellos. Se identificaron más vertebrados silvestres atropellados en zonas de baja urbanización que en áreas de media y alta. Conclusión: Nuestros resultados mostraron que los mamíferos son los vertebrados silvestres más vulnerables a los atropellamientos vehiculares. El riesgo de atropellamientos de animales silvestres está relacionado con el nivel de urbanización. Este estudio puede ser una herramienta en el desarrollo de carreteras sustentables para la fauna silvestre.

Abstract Introduction: Communication is part of economic and social development around the globe. The development of roads causes the fragmentation of natural ecosystems, increasing the mortality risk of wild animals due to vehicle collisions. Objective: To analyze the mortality rate of wild vertebrates run over according to the climatic season and the urbanization degree in the coastal area of the Guerrero state, in Southern Mexico. Methods: 12 trips with three observers using a vehicle at a speed of 30 km/h were conducted during one year (June 2021 to May 2022). The organisms were geo-referenced and identified. The roadkill rate (roadkill/day/km) was calculated for the wild vertebrates. Results: In total, 37 species of ran over wild vertebrates were registered, of which nine are considered endangered and seven are endemic of Mexico. Mammals had the highest mortality rate (0.126 roadkill/day/km). No differences were found in the mortality rate among rainy and dry seasons; 11 roadkill hotspots were detected. More incidences of roadkill were identified in low urbanization zones than medium and high urbanization areas. Conclusions: Our results showed that mammals are the most vulnerable wild vertebrates to vehicle collisions. The roadkill risk of wild animals is related to the urbanization level. This study can be a tool in the development of sustainable roads for wildlife.

Besides this, it was found that the relation of these three scenarios diagnoses to IgM Ab against toxoplasmosis are: pregnancy, ocular pathology and adenomegaly.

RESUMO Para ajustar a frequência alimentar de juvenis de cobia ou beijupirá (Rachycentron canadum), 540 juvenis, com peso médio de 2,0 g (± 0,4) e comprimento médio de 8,7cm (± 0,5), foram distribuídos em quatro tratamentos: T2, T4, T6 e T8 (alimentação realizada duas, quatro, seis e oito vezes ao dia, respectivamente). Cada tratamento teve três repetições. Os juvenis de beijupirá foram alimentados em regime ad libitum. Observou-se diferença significativa no peso final (P<0,05), tendo os peixes do tratamento que receberam ração duas vezes ao dia (T2) apresentado peso significativamente menor do que os peixes que receberam oito refeições ao dia (T8). Não houve diferença nas variáveis conversão alimentar, ganho de peso, comprimento e sobrevivência (P>0,05) entre os tratamentos. Assim, para juvenis de beijupirá, observou-se que a frequência de alimentação de oito refeições por dia, juntamente com um regime de alimentação ad libitum, é a mais adequada durante essa fase. Os dados obtidos no presente experimento permitem otimizar uma etapa da cadeia produtiva do beijupirá.

ABSTRACT Leptospirosis and toxoplasmosis are zoonoses of occupational character that are spread worldwide, mainly in tropical and socioeconomically vulnerable areas. Both diseases have vertebrate hosts, which spread the infectious agent to the environment and are potentially infectious to humans and can progress to fatal cases. The present study reinforces the importance of One Health for the control and prophylaxis of leptospirosis and toxoplasmosis using sentinel animals in areas of socioeconomic vulnerability based on a serological study. A total of 336 blood samples were obtained from the canine population of the urban district, which has high rates of poverty and sanitation. The results were analyzed based on seroreactivity animals and georeferencing by kernel spatial mapping. A total of 43.3% (52/120) of the animals were seroreagents for anti-Leptospira spp., with a predominance of Canicola (35/52 = 67.3%) and Pyrogenes (5/52 = 9.6%), while 52.97% (178/336) of the dogs were seroreactive for anti-Toxoplasma gondii. The presence of seroreagent dogs for both zoonosis alert to the inadequate hygienic-sanitary conditions of the studied region, and highlight the importance of a survey of the social, economic and environmental structure to identify factors related to the links in the epidemiological chain of pathogen transmission and necessary corrective actions. worldwide hosts cases 33 district sanitation mapping 433 43 3 43.3 52/120 52120 52 120 (52/120 antiLeptospira anti Leptospira spp spp. 35/52 3552 35 (35/5 67.3% 673 67 5/52 552 5 (5/5 9.6%, 96 9.6% , 9 6 9.6%) 5297 97 52.97 178/336 178336 178 (178/336 antiToxoplasma Toxoplasma gondii hygienicsanitary hygienic sanitary region social actions 4 43. 52/12 5212 12 (52/12 35/5 355 (35/ 67.3 5/5 55 (5/ 9.6 529 52.9 178/33 17833 17 (178/33 52/1 521 1 (52/1 35/ (35 67. 5/ (5 9. 52. 178/3 1783 (178/3 52/ (52/ (3 ( 178/ (178/ (52 (178 (17 (1

RESUMO Leptospirose e toxoplasmose são zoonoses de caráter ocupacional disseminadas mundialmente, principalmente em áreas tropicais e socioeconomicamente vulneráveis. Ambas as doenças têm hospedeiros vertebrados, que espalham o agente infeccioso para o meio ambiente e são potencialmente infecciosos para o homem, as quais podem evoluir para casos fatais. O presente estudo reforça a importância da saúde única para o controle e a profilaxia da leptospirose e da toxoplasmose, mediante a utilização de animais sentinela em áreas de vulnerabilidade socioeconômica, com base em estudo sorológico. Um total de 336 amostras de sangue foi obtido da população canina de um distrito urbano que apresenta altos índices de pobreza e ausência de saneamento básico. Os resultados foram analisados com base em animais sororreagentes e georreferenciados por mapeamento espacial de Kernel. Um total de 43,3% (52/120) dos animais foi sororreagente para anti-Leptospira spp., com predominância de Canicola (35/52 = 67,3%) e Pirogenes (5/52 = 9,6%), enquanto 52,97% (178/336) dos cães foram sororreagentes para anti-Toxoplasma gondii. A presença de cães sororreagentes para ambas as doenças alerta para as condições higiênico-sanitárias inadequadas da região estudada e evidencia a importância de um levantamento da estrutura social, econômica e ambiental para identificar fatores relacionados aos elos da cadeia epidemiológica de transmissão do patógeno e ações corretivas necessárias. mundialmente vulneráveis vertebrados homem fatais socioeconômica sorológico 33 básico Kernel 433 43 3 43,3 52/120 52120 52 120 (52/120 antiLeptospira anti Leptospira spp spp. 35/52 3552 35 (35/5 67,3% 673 67 5/52 552 5 (5/5 9,6%, 96 9,6% , 9 6 9,6%) 5297 97 52,97 178/336 178336 178 (178/336 antiToxoplasma Toxoplasma gondii higiênicosanitárias higiênico sanitárias social necessárias 4 43, 52/12 5212 12 (52/12 35/5 355 (35/ 67,3 5/5 55 (5/ 9,6 529 52,9 178/33 17833 17 (178/33 52/1 521 1 (52/1 35/ (35 67, 5/ (5 9, 52, 178/3 1783 (178/3 52/ (52/ (3 ( 178/ (178/ (52 (178 (17 (1
