RESUMO: O Rio Grande do Sul possui uma grande diversidade de espécies de répteis distribuídos por todo o Estado. Devido às ações antrópicas, como a fragmentação de habitats, estes animais vêm sendo observados com frequência no meio urbano e periurbano. Isso facilita a disseminação de patógenos entre animais e seres humanos, sendo um risco a saúde única, visto que muitas doenças são consideradas zoonoses. A leptospirose está entre as zoonoses mais comuns do mundo e é causada pelas espécies patogênicas da bactéria do gênero Leptospira. Ainda não se sabe o papel dos répteis no ciclo da doença, porém, estudos sorológicos demonstraram positividade para anticorpos contra Leptospira spp. em cágados e serpentes, o que pode indicar que estes animais atuam na manutenção do patógeno no ambiente. O objetivo deste estudo foi observar a presença de anticorpos anti-Leptospira em répteis oriundos de resgate e levados ao Núcleo de Reabilitação da Fauna Silvestre e Centro de Triagem de Animais Silvestres da Universidade Federal de Pelotas (NURFS-CETAS/UFPEL). As amostras foram coletadas de 55 animais (39 Trachemys dorbigni; 3 Philodryas patagoniensis; 3 Caiman latirostris; 3 Salvator merianae; 2 Acanthochelys spixii; 2 Phrynops hilarii; 2 Hydromedusa tectifera; 1 Philodryas aestiva), durante o período de agosto de 2022 a dezembro de 2023, e testadas para 12 sorovares de referência. Dois animais demonstraram positividade, um deles para o sorovar patogênico Pyrogenes e outro para o sorovar patogênico Canicola. Este resultado demonstra a importância de outras espécies, além dos mamíferos, como potenciais reservatórios e responsáveis pela manutenção da leptospirose no ambiente.

ABSTRACT: The state of Rio Grande do Sul has a great diversity of reptile species distributed throughout its territory. Due to human actions, such as habitat fragmentation, these animals have been frequently observed in urban and peri-urban environments. This facilitates the spread of pathogens between animals and humans, posing a unique health risk, as many diseases are considered zoonoses. Leptospirosis is among the most common zoonoses in the world and is caused by pathogenic species of bacteria of the genus Leptospira. The role of reptiles in the cycle of this disease is yet unknown. However, serological studies have demonstrated positivity for antibodies against Leptospira spp. in tortoises and snakes, which may indicate that these animals act in maintaining the pathogen in the environment. This observed the presence of anti-Leptospira antibodies in rescued reptiles taken to the Center for Rehabilitation of Wild Fauna and Screening Center for Wild Animals at the Universidade Federal de Pelotas (NURFS-CETAS/UFPEL). Samples were collected from 55 animals (39 Trachemys dorbigni; 3 Philodryas patagoniensis; 3 Caiman latirostris; 3 Salvator merianae; 2 Acanthochelys spixii; 2 Phrynops hilarii; 2 Hydromedusa tectifera; 1 Philodryas aestiva) from August 2022 to December 2023 and tested for 12 reference serovars. Two animals demonstrated positivity, one for the pathogenic serovar Pyrogenes and the other for the pathogenic serovar Canicola. This result reflected the importance of different species besides mammals as potential reservoirs and responsible for maintaining leptospirosis in the environment.

SUMMARY: In current study, we used Nissl staining to examine the histological structure of the juvenile Chinese alligator brain, and immunohistochemistry (IHC) staining to detail the serotonin (5-hydroxytryptamine, 5-HT) localization and morphology of neurons belonging to the serotonergic system. Nissl staining revealed that the Chinese alligator brain was divided into four regions (telencephalon, diencephalon, brainstem, and cerebellum) and a connected ventricular system (containing the pair of lateral ventricles, third ventricle, fourth ventricle and the aqueduct). According to the IHC results, 5-HT immunoreactive (5-HT-IR) neurons were primarily observed in the cerebral cortex, the hypothalamic paraventricular nucleus (PH), tectum and tegmentum of the optic lobes, the medial longitudinal fasciculus (Flm) of medulla oblongata and the cerebellar cortex. 5-HT-IR fibers were mostly located lateral to the hypothalamic paraventricular nucleus (PH), in the medial vestibular nucleus (MVe) of the medulla oblongata, and in the choroid plexus (CP) of the lateral ventricles. Additionally, our findings paralleled those results of other reptiles; nevertheless, some distinctions in terms of both histological architecture and function were identified. The layering of the cerebral cortex and tectum, as well as the arrangement of Purkinje cells, differed between reptile brains. The distribution of 5-HT-IR neurons varied in the layer of cerebral and cerebellar cortex when compared to other reptiles. Within the diencephalon, 5-HT-IR neurons formed distinct nuclei in the hypothalamic paraventricular nucleus (PH), but few in the infundibular recess.

RESUMEN: Utilizamos la tinción de Nissl para examinar la estructura histológica del cerebro juvenil del caimán chino y la tinción inmunohistoquímica (IHC) para detallar la localización y morfología de la serotonina (5-hidroxitriptamina, 5-HT) de las neuronas que pertenecen al sistema serotoninérgico. La tinción de Nissl reveló que el cerebro del caimán chino estaba dividido en cuatro regiones (telencéfalo, diencéfalo, tronco encefálico y cerebelo) y un sistema ventricular conectado (que contiene el par de ventrículos laterales, el tercer ventrículo, el cuarto ventrículo y el acueducto). Según los resultados de IHC, las neuronas inmunorreactivas 5-HT (5-HT-IR) se observaron principalmente en la corteza cerebral, el núcleo paraventricular (PH) hipotalámico, el tectum y tegmento de los lóbulos ópticos, el fascículo longitudinal medial (Flm) de médula oblonga y la corteza cerebelosa. Las fibras 5-HT-IR se ubicaron principalmente lateral al núcleo paraventricular (PH) hipotalámico, en el núcleo vestibular medial (MVe) de la médula oblonga y en el plexo coroideo (CP) de los ventrículos laterales. Además, nuestros hallazgos fueron semejantes a los resultados obtenidos de otros reptiles; sin embargo, se identificaron algunas distinciones en términos tanto de arquitectura histológica como de función. Las capas de la corteza cerebral y el tectum, así como la disposición de las neuronas purkinjenses, diferían entre los cerebros de los reptiles. La distribución de las neuronas 5-HT-IR varió en la capa de la corteza cerebral y cerebelosa en comparación con otros reptiles. Dentro del diencéfalo, las neuronas 5-HT-IR formaron núcleos distintos en el núcleo paraventricular (PH) hipotalámico, pero pocos en el receso infundibular.

Resumen Se presentan los resultados del análisis de los restos faunísticos recuperados en el sitio arqueológico Los Conitos (valle de Potrerillos, Mendoza, Argentina). El sitio posee dataciones absolutas que definen las ocupaciones en un rango cronológico entre los ca. 796-3694 años AP (cal 2σ). Se recuperaron evidencias de macro restos de plantas domésticas, registro imprescindible para evaluar las prácticas agrícolas prehispánicas en el centro occidente argentino. El análisis tafonómico realizado en el presente estudio permitió identificar a humanos y depredadores no antrópicos (probablemente pequeños carnívoros) como los agentes responsables de dichas acumulaciones. En cuanto a las evidencias antrópicas, se detectaron huellas de corte sobre huesos de Lama guanicoe. Se registraron especímenes asignables al roedor octodóntido extinto Octomys rosiae. Los mamíferos fueron el grupo más frecuente, dominado por roedores, aunque se detectaron armadillos, marsupiales y lepóridos en baja proporción. También se recuperaron escasos elementos asignados a reptiles y aves. Se observó una considerable cantidad de elementos modificados por digestión. También se identificaron perforaciones por carnívoros. El ensamble zooarqueológico evidencia la co-ocurrencia de especies con distribuciones actualmente alopátricas.

Abstract In this paper, the results of the analyses of bone remains recovered in the Los Conitos archaeological site (Potrerillos Valley, Mendoza, Argentina) are presented. The site covers a chronological range of c. 796-3694 years BP (cal 2σ). Numerous domestic plant macro remains were recovered at the site, the record of which is an important source for evaluating pre-Hispanic farming strategies in central-western Argentina. Taphonomic analysis enabled the identification of human and non-anthropic predators (probably small carnivores) as the responsible agents of such accumulations. Regarding anthropic evidence, only two cut marks were detected on two bones of Lama guanicoe. Bone specimens of the extinct octodontid rodent Octomys rosiae were recovered. Mammals were the most represented taxonomic group, dominated by rodents; although armadillos, marsupials and leporids were detected in low proportion. Bone remains of birds and reptiles were scarce. We observed a considerable number of specimens that were modified by digestion, with strong degrees of modification. Punctures associated with carnivore activity were also recorded. The zooarchaeological assemblage shows the co-occurrence of species with current allopatric distributions.

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 Hepatozoon spp. are the most common haemoparasites reported from reptiles around the world, however, only six species have been described infecting crocodilians. In Brazil, Hepatozoon caimani Carini, 1909 is currently the only recognized species from the caiman hosts. This study provides new data on the diversity of species of Hepatozoon infecting Caiman crocodilus (Linnaeus) using molecular data and phylogenetic analysis, with additional support of morphological data of developmental stages from host blood and tissue. Forty-four individuals were collected and screened for haemogregarines, and blood and tissue samples were analysed by light microscopy with 31 (70.45%) infected. Hepatozoon spp. blood developmental stages included immature and mature gamonts with or without cytoplasmic vacuoles and free gamonts. Additionally, merogonic developmental stages were found in the liver and spleen of infected hosts. Based on the morphological and molecular data, this study identified two possible different species of Hepatozoon, being one of them the H. caimani with intragenotypic divergence. spp world however crocodilians Brazil Carini 190 hosts Linnaeus (Linnaeus analysis Fortyfour Forty four haemogregarines 3 70.45% 7045 70 45 (70.45% Additionally H divergence 19 70.45 704 7 4 (70.45 1 70.4 (70.4 70.

Resumo Hepatozoon spp. são os hemoparasitas mais comuns relatados em répteis em todo o mundo, no entanto, apenas seis espécies foram descritas infectando crocodilianos. No Brasil, Hepatozoon caimani Carini, 1909 é atualmente a única espécie reconhecida dos hospedeiros jacarés. Este estudo fornece novos dados sobre a diversidade de espécies de Hepatozoon que infectam Caiman crocodilus (Linnaeus) utilizando dados moleculares e análise filogenética, com suporte adicional fornecido através de dados morfológicos de estágios de desenvolvimento do sangue e tecido do hospedeiro. Quarenta e quatro indivíduos foram coletados e triados para hemogregarinas, e amostras de sangue e tecidos foram analisadas por microscopia óptica com 31 (70,45%) infectados. Os estágios de desenvolvimento do sangue incluíram gamontes imaturos e maduros com ou sem vacúolos citoplasmáticos e gamontes livres. Além disso, foram encontrados estágios de desenvolvimento merogônico no fígado e baço de hospedeiros infectados. Com base nos dados morfológicos e moleculares, este estudo identificou duas possíveis espécies diferentes de Hepatozoon, sendo uma delas, o H. caimani com divergência intragenotípica. spp mundo entanto crocodilianos Brasil Carini 190 jacarés Linnaeus (Linnaeus filogenética hospedeiro hemogregarinas 3 70,45% 7045 70 45 (70,45% infectados livres disso delas H intragenotípica 19 70,45 704 7 4 (70,45 1 70,4 (70,4 70, (70, (70 (7 (

Resumo Durante o presente estudo, os espécimes foram coletados em locais selecionados do deserto do Cholistan e da Reserva de Caça de Kalabagh, província de Punjab, Paquistão. Cada espécime capturado foi etiquetado com o número do comprovante e medidas morfométricas foram realizadas. O comprimento médio do focinho à cloaca foi de 172,559 ± 1,40 mm, e o peso médio foi de 92,1 ± 1,30 g. O DNA de Uromastyx hardwickii foi amplificado e sequenciado usando o conjunto de primer 16S rRNA. A sequência de DNA obtida mostrou identificação de espécies confiável e clara. Após o corte de bases ambíguas, o fragmento de rRNA 16S obtido tinha 520 pb, enquanto os fragmentos de rRNA 16S alinhados com a sequência próxima do NCBI composta por 510 pb. Sequências semelhantes do gênero Uromastyx foram recuperadas do NCBI em pesquisas de explosão. A árvore de união de vizinhos do gênero Uromastyx foi construída com base na distância-p usando MEGA X. A variação intraespecífica média foi de 0,095 ± 0,01, enquanto a variação intraespecífica foi de 0-1%. Da mesma forma, a variação interespecífica de Uromastyx hardwikii com Saara asmussi, Uromastyx alfredschmidti, Uromastyx geyri, Uromastyx thomasi, Uromastyx alfredschmidti foi de 0-12%, 0-19%, 0-19%, 0-20%, 12-19%, respectivamente. O DNA recém-produzido foi submetido ao NCBI e o número de acesso foi obtido (MW052563.1). Os resultados do estudo atual forneceram informações sobre a identificação molecular e morfológica do Gênero Uromastyx. Em nossa recomendação, a identificação de base molecular abrangente de répteis do Paquistão é necessária para relatar qualquer nova ou subespécie do país.

Abstract During the present study, specimens were collected from selected sites of Cholistan desert and Kalabagh Game Reserve, Punjab province, Pakistan. Each captured specimen was tagged with voucher number and morphometric measurements were taken. The average snout to vent length was 172.559±1.40 mm and average weight was 92.1±1.30 g. The DNA of Uromastyx hardwickii was amplified and sequenced using 16S rRNA primer set. The obtained DNA sequence has shown reliable and clear species identification. After trimming ambiguous bases, the obtained 16S rRNA fragment was 520 bp while 16S rRNA fragments aligned with closely matched sequence from NCBI comprised of 510 bp. Closely matched sequences of genus Uromastyx were retrieved from NCBI in blast searches. Neighbour-joining tree of genus Uromastyx was constructed based on p-distance using MEGA X. The mean intraspecific variation was 0.095±0.01 while intraspecific variation was ranging from 0-1%. Similarly, interspecific variation of Uromastyx hardwikii with Saara asmussi, Uromastyx alfredschmidti, Uromastyx geyri, Uromastyx thomasi, Uromastyx alfredschmidti was 0-12%, 0-19%, 0-19%, 0-20%, 12-19% respectively. The newly produced DNA was submitted to NCBI and accession number was obtained (MW052563.1). Results of current study provided information about the molecular and morphological identification of Genus Uromastyx. In our recommendation, comprehensive molecular based identification of Pakistan’s reptiles is required to report any new or subspecies from country.

Resumo A mineração é vital para o sustento humano e um setor crucial na economia do Estado. No entanto, seus impactos sobre o meio ambiente e a biodiversidade não podem ser subestimados, visto serem potentes para atrair a atenção do governo. O meio ambiente e a vida selvagem estão sujeitos aos impactos prejudiciais da mineração e de suas atividades relacionadas. Neste estudo, os distritos, nomeadamente Mardan e Mohmand, foram selecionados no que diz respeito aos impactos da mineração. A avaliação foi realizada em animais selvagens afetados negativamente pelo setor de mineração. A fauna tem sido observada atentamente para trazer os riscos calculados e a percepção de ameaça à vida selvagem regional. Um total de nove espécies de mamíferos, 21 espécies de pássaros, foi registrado no Distrito Mardan. Enquanto no Distrito Mohmand, duas espécies de mamíferos, nove espécies de pássaros e quatro espécies de répteis foram estudadas. O estudo explorou essa mineração que é principalmente responsável pela degradação do solo, acarretando perdas de alimentos e na agricultura. Vários outros fatores como explosões, poluição, caça, desmatamento, perda de habitat também foram observados. O desmatamento veio à tona como uma das principais causas de extinção da fauna da região, e tem-se que medidas preventivas são necessárias para dimensionar a catástrofe provocada pelo homem.

Abstract Mining is vital for human sustenance and a crucial sector in the state economy. However, its impacts on the environment and biodiversity cannot be underestimated. Which are potent to the attract government’s attention. Environment and wildlife are subject to the harmful impacts of mining and its related activities. In this study, districts, namely Mardan and Mohmand have been targeted with respect to mining impacts. The assessment was carried out on wildlife adversely affected by the mining sector. The fauna has been keenly observed to bring the calculated risks and threat perception of the regional wildlife. Total 9 species of mammals, 21 species of birds, were recorded in District Mardan. While in District Mohmand 2 species of mammals, 9 species of birds, and 4 species of reptiles were studied. The Study explored that mining primarily responsible for land degradation. Which lead to food and agriculture losses. Several other factors like blasting, pollution, hunting, deforestation, habitat loss was also observed. Deforestation surfaced one of the major causes for extinction of fauna in the said region. preemptive measures are needed to seize the man-made catastrophe.

Resumo Anfisbênas são répteis fossoriais caracterizadas por apresentarem corpo cilíndrico e alongado coberto por escamas dispostas exclusivamente em anéis e todas são ápodas, com exceção das três espécies do gênero Bipes. Sua dieta consiste em uma variedade de invertebrados e pequenos vertebrados. Por viverem no subsolo, muitos aspectos de sua história natural são difíceis de observar. A maioria dos estudos sobre alimentação em anfisbenas concentra-se na dieta e na ecologia alimentar, enquanto as informações sobre o comportamento alimentar se baseiam em observações preliminares. O objetivo deste artigo foi descrever o comportamento de captura de alimentos exibido por Leposternon microcephalum Wagler, 1824, fora da galeria, em cativeiro. Para o experimento foi utilizada uma isca não viva, ração úmida de gato, que foi oferecida e posicionada próxima a uma das aberturas da galeria, na superfície do solo. Um total de três animais foi analisadopor meio de observações visuais e registros de câmeras de telefones celulares posicionadas em um ponto fixo, captando imagens de suas vistas dorsal e lateral. Foram detectados dois tipos principais de comportamento: captura de recursos alimentares e mecanismo de defesa. As estratégias utilizadas para capturar o recurso alimentar foram semelhantes às observadas em outras espécies fossoriais. Embora o movimento de “marcha-à-ré” tenha sido observado e descrito, o registramos sendo usado como uma estratégia de fuga. Esses resultados contribuem para enriquecer o conhecimento sobre diferentes aspectos da história natural dos Amphisbaenia.

Abstract Amphisbaenians are fossorial reptiles that have a cylindrical and elongated body covered with scales arranged in rings, and are all apodal, except for the three species of the genus Bipes. The amphisbaenian diet consists of a variety of invertebrates and small vertebrates. As these animals live underground, many aspects of their natural history are difficult to study. Most feeding studies of amphisbaenians have focused on the composition of the diet and feeding ecology, and the data available on feeding behavior are based on precursory observations. The present study describes the food capture behavior of Leposternon microcephalum Wagler, 1824 in captivity. In this experiment we used non-live bait (moist cat food), which was placed near a burrow opening, on the surface of the substrate. Three animals were monitored visually and filmed using cellphone cameras deployed at fixed points, to capture images from the dorsal and lateral perspectives of the study subjects. Two principal types of behavior were observed: the capture of food and defense mechanisms. The strategies used to capture the food were similar to those observed in other fossorial species. Although the backward movement has already been observed and described, we were able to record this movement being used as an escape strategy. These findings enrich our knowledge on different aspects of the natural history of the amphisbaenians.

Abstract Information regarding species occurrence is fundamental to understanding biodiversity distribution. However, the biodiversity from the west of the state of Paraná has been historically less studied, especially amphibians and reptiles. For this reason, we present the first reptile list of species from the west of the state of Paraná and extend the current list of anurans for the municipality of Foz do Iguaçu. The species list was based on a systematic field study conducted at Refúgio Biológico Bela Vista (RBV) a conservation area within the Hydroelectric Power Itaipu Binacional. We integrated the species list with previous species observations available in the literature for the same place where our sampling was conducted. A total of 41 species of amphibians and reptiles are presented. All amphibians species found were recorded in the field; however, from the 22 species of reptiles recorded, three were historical records obtained before this study. Species were all classified as Least Concern and/or had stable populational status according to the IUCN. Sampling sufficiency was achieved for anurans but not for reptiles, probably due to low abundance of several snake species. The most abundant species of anuran was Dendropsophus nanus, from the Hylidae family, whereas Leptodactylus plaumanni and Scinax squalirostris were represented by only one individual each. The lizard Salvator merianae was the most abundant reptile, and seven species were represented by only one individual each. The most successful sampling method for adult anurans was active search in water bodies whereas most of reptile species were observed by accidental encounters and not through a systematic sampling method. We found that herpetofauna composition from RBV was similar to other communities from Paraná state that also occur within the Semideciduous Seasonal Forest. Finally, as additional information to the species list, we offer species identification keys and discuss the importance of Refúgio Biológico Bela Vista to harbor the anuran and reptile diversity of the region. distribution However studied reason Iguaçu (RBV Binacional 4 presented however 2 andor or IUCN nanus family each Forest Finally region

Resumo Informações sobre a ocorrência de espécies são fundamentais para a compreensão da distribuição da biodiversidade. Porém, a biodiversidade do oeste do Estado do Paraná tem sido historicamente menos estudada, especialmente a de anfíbios e répteis. Por esse motivo, apresentamos a primeira lista de espécies de répteis do oeste do Estado do Paraná e ampliamos a lista atual de anuros para o município de Foz do Iguaçu. A lista de espécies foi baseada em um estudo sistemático de campo realizado em uma área de conservação dentro da Usina Hidrelétrica Itaipu Binacional. Integramos a lista de espécies com observações de espécies anteriores disponíveis na literatura para o mesmo local onde nossa amostragem foi realizada. Um total de 41 espécies são apresentadas. Todas as espécies de anuros encontradas foram registradas em campo; entretanto, das 22 espécies de répteis registradas, três foram registros obtidos antes deste estudo. Todas as espécies foram classificadas como “Pouco Preocupante” e/ou tinham status de “População Estável” de acordo com a IUCN. A suficiência amostral foi alcançada para anuros, mas não para répteis, provavelmente devido à baixa abundância de diversas espécies de serpentes. A espécie de anuro mais abundante foi Dendropsophus nanus, da família Hylidae, enquanto Leptodactylus plaumanni e Scinax squalirostris foram representados por apenas um indivíduo cada. O lagarto Salvator merianae foi o réptil mais abundante, e sete espécies foram representadas por um indivíduo cada. O método de amostragem mais bem sucedido para anuros adultos foi a busca ativa em corpos d’água, enquanto a maioria das espécies de répteis foi observada por encontros acidentais e não através de um método de amostragem sistematizado. Descobrimos que a composição da herpetofauna do Refúgio Biológico Bela Vista foi semelhante à de outras comunidades do estado do Paraná que também ocorrem dentro da Floresta Estacional Semidecidual. Por fim, como informações adicionais à lista de espécies, oferecemos chaves de identificação das espécies e discutimos sobre a importância da área de Itaipu para abrigar a diversidade de anuros e répteis da região.

Abstract Natural History Collections (NHCs) represent the world’s largest repositories of long-term biodiversity datasets. Specimen collection and voucher deposition has been the backbone of NHCs since their inception, but recent decades have seen a drastic decline in rates of growth via active collecting. Amphibians and reptiles are amongst the most threatened zoological groups on the planet and are historically underrepresented in most worldwide NHCs. As part of an ongoing project to review the Portuguese zoological collections in the country’s NHCs, herpetological data from its three major museums and smaller collections was gathered and used to examine the coverage and representation of the different taxa extant in Portugal. These collections are not taxonomically, geographically, or temporally complete. Approximately 90% of the Portuguese herpetological taxa are represented in the country’s NHCs, and around half of the taxa are represented by less than 50 specimens. Geographically, the collections cover less than 30% of the country’s territory and almost all of the occurring taxa have less than 10% of their known distribution represented in the collections. A discussion on the implications for science of such incomplete collections and a review of the current status of Portuguese NHCs is presented.

Abstract The study aimed to characterize the digestive tract of Uranoscodon superciliosus and its associations to the diet and foraging behavior already described for the species. Five lizards were captured in forest areas near the city of Manaus, Amazonas, Brazil. Tongue, oesophagus, stomach, small and large intestines fragments were collected, fixed, and processed for light microscopy. Hyaline cartilage was present in the center of the tongue, and the papillae from the apex and glands from the radix showed positive reaction to Alcian blue. The oesophagus presented a folded mucosa, covered by an epithelium with mucous and goblet cells positive to PAS and Alcian blue. There was presence of gastric glands in the cardic and fundic stomach regions, plus all the regions reacted positively to PAS. Fold and villi variations in both small and large intestine were noted, as well as the number and arrangement of goblet cells. Mucous and goblet cells from the small intestine were positively stained in PAS, while only the goblet cells were Alcian blue positive. These findings indicate that the Amazonian Diving Lizard’s digestive tract organs, mainly the tongue and stomach, present morphologies associated to ambush-type foraging and a specific diet largely based on small invertebrates. species Manaus Amazonas Brazil Tongue collected fixed microscopy mucosa noted Lizards Lizard s organs ambushtype ambush type invertebrates

Abstract Fishermen-hunter-gatherers of sambaquis (Brazilian shell mounds) had an intimate affinity with marine-coastal environments, where they exploited a great variety of fish and mollusks that comprise the best documented fauna from sambaquis. However, other groups of animals as mammals, birds, reptiles, and amphibians are also present in these sites, but are relatively less studied. This paper is the first one focused exclusively on the Tetrapoda biodiversity of sambaquis and aimed to identify tetrapods of ten sites from southern Brazil. We present a faunal inventory and data regarding animal capture and environmental exploitation. We identified the specimens anatomically and taxonomically, analyzed them concerning fragmentation, and quantified the data for the number of identified specimens (NISP) and minimum number of individuals (MNI). Despite the high degree of fragmentation of remains, we identified 46 taxa. As expected, most were from marine animals: cetaceans (total NISP = 2,568 and MNI = 27), otariids (total NISP = 248 and MNI = 32), and seabirds (total NISP = 65 and MNI = 23), indicating great relevance of marine tetrapod fauna as a resource for sambaqui builders (79.39% of NISP). We thus document the close bond between fishermen-hunter-gatherers of sambaquis and the marine tetrapods in southern Brazil.

ABSTRACT: Iguanids are susceptible to several bacterial infections, especially those caused by Gram-negative bacteria. The development of these diseases in reptiles is related to management, inadequate sanitary conditions, and immunosuppression. This study aims to describe the anatomopathological and microbiological aspects of a case of co-infection by Plesiomonas shigelloides, Citrobacter freundii and Aeromonas jandaei diagnosed in a free-living green iguana (Iguana iguana). Macroscopically, the lesions were mainly located in skeletal muscle, myocardium, small intestine, and liver, characterized by white-yellowish, multifocal, friable, irregular areas associated with necrosis and hemorrhage. In the histopathological analysis, basophilic bacillary structures corresponding to bacterial aggregates were observed in the skeletal muscle, myocardium, hepatic parenchyma, kidney, stomach and small intestine associated with areas of thrombosis, necrosis and hemorrhage. The diagnosis of sepsis by P. shigelloides, C. freundii and A. jandaei was confirmed by matrix-assisted laser desorption/ionization time of flight (MALDI-TOF) associated with the anatomopathological and microbiological findings observed in this case.

RESUMO: Iguanídeos são suscetíveis a diversas infecções bacterianas, principalmente aquelas causadas por bactérias Gram-negativas. O desenvolvimento destas enfermidades em répteis está relacionado a manejos, condições sanitárias inadequadas e imunossupressão. Este estudo tem por objetivo descrever os aspectos anatomopatológicos e microbiológicos de um caso de coinfecção por Plesiomonas shigelloides, Citrobacter freundii e Aeromonas jandaei diagnosticado em uma iguana verde de vida livre (Iguana iguana). Macroscopicamente, as lesões localizavam-se principalmente em musculatura esquelética, miocárdio, duodeno e fígado, caracterizando-se por áreas branco-amareladas, multifocais, friáveis, e irregulares associadas à necrose e hemorragia. No histopatológico foram vistas estruturas bacilares basofílicas correspondentes a agregados bacterianos em músculo esquelético, miocárdio, parênquima hepático, rim, estômago e intestino delgado associados a áreas de trombose, necrose e hemorragia. O diagnóstico de sepse por P. shigelloides, C. freundii e A. jandaei foi confirmado pela técnica de ionização por dessorção a laser assistida por matriz com analisador por tempo de voo (MALDI-TOF) associada aos achados anatomopatológicos e microbiológicos observados neste caso.

RESUMO Lontra longicaudis é um predador semi-aquático com dieta principal a base de peixes e crustáceos, mas que oportunisticamente pode predar mamíferos, aves e répteis. Na Amazônia, essa espécie ocorre em simpatria com Paleosuchus trigonatus, uma das menores espécies de crocodilianos, apresentando como possível meio de defesa uma pele extremamente rígida, o que faz com que adultos tenham poucos predadores. Aqui nós relatamos o primeiro caso documentado de predação de P. trigonatus por L. longicaudis. semiaquático semi aquático crustáceos mamíferos répteis Amazônia crocodilianos rígida predadores P L

ABSTRACT Lontra longicaudis is a semi-aquatic predator which mainly feeds on fish and crustaceans, but which can opportunistically predate mammals, birds, and reptiles. In the Amazon, this species is sympatric with Paleosuchus trigonatus, one of the smallest species of crocodilians, whose possible means of defense is a very rigid skin, which causes adults to have few predators. Here we report the first documented case of predation of P. trigonatus by L. longicaudis. semiaquatic semi aquatic crustaceans mammals birds reptiles Amazon crocodilians skin predators P L

Resumen Se analizó la dieta de gatos (Felis silvestris catus) y perros (Canis lupus familiaris) errantes de la Reserva Ecológica del Pedregal de San Ángel (REPSA), Ciudad Universitaria, UNAM, Ciudad de México. Se examinaron 12 muestras de gatos y 55 de perros obtenidas mediante el Programa de Remediación de Fauna Feral, Secretaría Ejecutiva de la REPSA. La determinación de las especies consumidas se realizó comparando el material con ejemplares depositados en colecciones científicas; adicionalmente para mamíferos, se utilizaron patrones morfológicos de la cutícula y médula del pelo. El análisis mostró que la dieta de gatos y perros está compuesta, principalmente, de mamíferos medianos (Bassariscus astutus, Didelphis virginiana, Otospermophilus variegatus, Spilogale angustifrons y Sylvilagus floridanus) y pequeños (Mus musculus, Neotoma mexicana, Peromyscus gratus, Rattus norvegicus, Reithrodontomys fulvescens y Sorex saussurei), en menor proporción de reptiles e insectos, y material alimenticio de consumo humano. Los mamíferos nativos son más consumidos que los introducidos y que la dieta de gatos y perros incluye especies endémicas de México (S. saussurei, P. gratus y Peromyscus melanophrys) o en alguna categoría de riesgo (S. saussurei y la lagartija Sceloporus grammicus). Estos resultados proveen información para justificar y desarrollar alternativas de conservación en reservas ecológicas urbanas.

Abstract Diet analysis was performed on free ranging cats (Felis silvestris catus) and dogs (Canis lupus familiaris) from Reserva Ecológica del Pedregal de San Ángel (REPSA), Ciudad Universitaria, UNAM, Mexico City. Twelve samples of cats and 55 of dogs were analyzed as part of the Wildlife Remediation Program of the REPSA’s Executive Secretariat. The determination of consumed species was made by comparing the obtained remains with specimens deposited in scientific collections; additionally, for mammals, morphological scales patterns and hair marrow were examined. Our results showed that the diet of cats and dogs is mainly composed of medium-size mammals (Bassariscus astutus, Didelphis virginiana, Otospermophilus variegatus, Spilogale angustifrons, and Sylvilagus floridanus) and small mammals (Mus musculus, Neotoma mexicana, Peromyscus gratus, Rattus norvegicus, Reithrodontomys fulvescens, and Sorex saussurei), with a smaller proportion of reptiles and insects and food material for human consumption. The native mammals are consumed more than introduced mammals, and that diet of cats and dogs includes species endemic to Mexico (S. saussurei, P. gratus, and Peromyscus melanophrys) or in any risk category (S. saussurei and the lizard Sceloporus grammicus). These results provide information for justify and developing conservation alternatives in urban ecological reserves.
