Abstract Introduction: The Aedes vittatus mosquito is an important vector of yellow fever in Africa, with vectorial competence for dengue, chikungunya and Zika. Its presence has been reported in some places in Africa, Asia, Europe, and -recently- America. However, information on its distribution is fragmented, with limited descriptions of the specific characteristics of its habitats. Objective: To compile records of its occurrence, describe the ecological characteristics of its habitat and estimate its current and future global potential invasion. Methods: We employed both first-record data and global occurrence records to describe its habitat. Additionally, we used an ecological niche model, specifically the MaxEnt algorithm, with bioclimatic variable layers to estimate potential invasion areas. Since the native range of A. vittatus is unknown, we calibrated accessible areas using two hypotheses, Africa and Asia, based on available genetic information. Results: Regardless of its native area, A. vittatus appears to be distributed in tropical and subtropical areas in all continents with potential to reach even currently colder climates as global climate change. It is found mainly in tropical and urban areas, likely through transcontinental and terrestrial passive transport. Conclusions: The mosquito can be found on all continents, ranging from sea level to 2 500 m.a.s.l., at temperatures between 15 and 30 °C, and has the potential for further expansion.

Resumen Introducción: El mosquito Aedes vittatus es un importante vector de la fiebre amarilla en África, con competencia vectorial para el dengue, la chikungunya y el Zika. Se ha informado de su presencia en algunas áreas de África, Asia, Europa y, recientemente, América. Sin embargo, la información sobre su distribución es fragmentada, con descripciones limitadas de las características específicas de sus hábitats. Objetivo: Recopilar registros de su presencia, describir las características ecológicas de su hábitat y estimar su potencial de invasión actual y futuro a nivel mundial. Métodos: Utilizamos datos de primeros registros y registros de presencia a nivel global para describir su hábitat. Además, empleamos un modelo de nicho ecológico, específicamente el algoritmo MaxEnt, con capas de variables bioclimáticas para estimar las áreas de potencial invasión. Dado que se desconoce el área nativa de A. vittatus, calibramos áreas accesibles bajo dos hipótesis, África y Asia, basadas en la información genética disponible. Resultados: Independientemente de su área nativa, A. vittatus parece distribuirse en regiones tropicales y subtropicales en todos los continentes, con el potencial de expandirse incluso hacia climas actualmente más fríos debido al cambio climático global. Se encuentra principalmente en áreas tropicales y urbanas, posiblemente a través del transporte pasivo transcontinental y terrestre. Conclusiones: El mosquito se puede encontrar en todos los continentes, desde el nivel del mar hasta altitudes de 2 500 m.s.n.m., a temperaturas que oscilan entre 15 y 30 °C, y presenta el potencial para una mayor expansión geográfica.

Pinguicula crassifolia, P. michoacana, P. tlahuica y P. zamudioana son endémicas de la FVTM.

Abstract Background: The genus Pinguicula harbors 110 species, of which 53 are distributed in Mexico. The formation of the Mexican mountains has favored the Pinguicula diversification. Pinguicula specimens collected in the State of México, along the Trans-Mexican Volcanic Belt (TMVB) do not correspond with any known species. Questions: Do the collected specimens belong to a new species? What is its conservation status? How many Pinguicula species are there along the TMVB and how do they differentiate? How is the Pinguicula species richness distributed? Studied species: Pinguicula. Study site and dates: TMVB, 2005-2023. Methods: Based on herbarium specimens and recently collected material, a morphological analysis and description were made. Conservation status was assessed following IUCN Red List Categories and Criteria. Herbarium specimens and digital records of Pinguicula from the TMVB were examined to generate a list and key. We analyzed the richness distribution of Pinguicula by states, vegetation types, elevation ranges, and grid cells. Results: Pinguicula tlahuica is proposed as a new species. It is distinguished by the linear-spatulate summer leaves. The new species falls into the Endangered (EN) category. Along the TMVB, 16 species of Pinguicula are distributed. The State of México, Hidalgo and Michoacán, and the pine-oak forest were the richest. Pinguicula appeared between 759-3,427 m asl. The grid cell analyses revealed different areas with high richness. Conclusions: Along the TMVB, the Pinguicula species richness centered on the Eastern and Western sectors. Pinguicula crassifolia, P. michoacana, P. tlahuica, and P. zamudioana are endemic to the TMVB.

Brejos Nordestinos (northeastern highland wet forests) is a unique ecosystem within the Northeastern Atlantic Forest. This area encompasses a mosaic of humid forests above 600 meters in the semi-arid region, forming an ecotone area. These environmental conditions create an optimal ecosystem for the diversification of plants, including ferns. Pico do Jabre in Paraíba state, with an elevation of 1,208 meters above sea level, is an example of Brejo Nordestino. This study reports the occurrence of Pleopeltis pleopeltidis in the Northeastern Atlantic Forest, particularly at Pico do Jabre, a new record of P. pleopeltifolia for Paraíba state, and the local fern flora. Additional records of P. pleopeltidis were found in the municipalities of Triunfo, and Floresta, in Pernambuco state, which are also classified as Brejos Nordestinos with elevations exceeding 1,000 meters above sea level. These findings extend the species' known extent of occurrence by approximately 40%. The conservation status of P. pleopeltidis is suggested as Vulnerable (VU) across its entire range and Endangered (EN) in Northeast Brazil. The distance between populations in the Northeastern Atlantic Forest and the nearest populations in Bahia state ranges from 763-931 km, indicating a potential disjunction. Although the species occurs in three relatively close Brejos Nordestinos, the fragmented nature of the Northeastern Atlantic Forest results in isolated populations on these biogeographical islands, surrounded by a Caatinga (seasonally dry tropical forest) matrix.

Los Brejos Nordestinos (bosques húmedos de tierras altas del noreste) son un ecosistema único dentro del Bosque Atlántico del Nordeste. Esta área abarca un mosaico de bosques húmedos por encima de los 600 metros en la región semiárida, formando una zona de ecotono. Estas condiciones ambientales crean un ecosistema óptimo para la diversificación de plantas, incluidos los helechos. El Pico do Jabre, en el estado de Paraíba, con una altitud de 1208 metros sobre el nivel del mar, es un ejemplo de Brejo Nordestino. Este estudio reporta la ocurrencia de Pleopeltis pleopeltidis en el Bosque Atlántico del Nordeste, particularmente en el Pico do Jabre, un nuevo registro de P. pleopeltifolia para el estado de Paraíba, y en la flora local de helechos. Se encontraron registros adicionales de P. pleopeltidis en los municipios de Triunfo y Floresta, en el estado de Pernambuco, que también están clasificados como Brejos Nordestinos con elevaciones superiores a los 1000 metros sobre el nivel del mar. Estos hallazgos amplían la extensión conocida de ocurrencia de la especie en aproximadamente un 40%. Se sugiere que el estado de conservación de P. pleopeltidis sea vulnerable (VU) en toda su área de distribución y en peligro (EN) en el noreste de Brasil. La distancia entre las poblaciones del Bosque Atlántico del Nordeste y las poblaciones más cercanas en el estado de Bahía varía entre 763 y 931 km, lo que indica una posible disyunción. Aunque la especie ocurre en tres Brejos Nordestinos relativamente cercanos, la naturaleza fragmentada del Bosque Atlántico del Nordeste da como resultado poblaciones aisladas en estas islas biogeográficas, rodeadas por una matriz de Caatinga (bosque tropical seco estacionalmente).

Resumen Los reportes del exceso de mortalidad durante la pandemia por COVID-19 en Argentina han sido parcia les y fragmentados hasta el momento. Este estudio se propuso cuantificar el exceso de muertes y explorar su distribución demográfica, temporal y geográfica durante el periodo 2020-2022. Utilizando datos de 1 192 963 registros de muertes de estadísticas vitales y proyecciones poblacionales, se estimó la mortalidad esperada mediante modelos de regresión. El exceso de muertes se calculó como la diferencia entre la mortalidad observada y la esperada. Se estimó un exceso de 160 676 muertes (IC 95% 146 861 a 174 491), representando una tasa de 116.9 muer tes (IC 95% 115.5 a 118.3) adicionales por cada 100 000 personas-año. Se verificó una significativa heterogenei dad entre las distintas provincias argentinas. Los resultados indican un impacto desigual de la pandemia, con mayores tasas de exceso de mortalidad en algunas regiones y grupos de edad más vulnerables. Estos patrones sugieren la necesidad de estrategias diferenciadas de respuesta sanitaria y apoyo a las poblaciones más vulnerables en escenarios de nuevas epidemias.

Abstract Reports of excess mortality during the COVID-19 pan demic in Argentina have been partial and fragmented so far. This study aimed to quantify excess deaths and explore their demographic, temporal, and geographic distribution during the period 2020-2022. Using data from 1 192 963 death records from vital statistics and population projections, expected mortality was estimated using regression models. Excess death was calculated as the difference between observed and expected mortality. An excess of 160 676 deaths (95% CI 146 861 to 174 491) was estimated, representing a rate of 116.9 (95% CI 115.5 to 118.3) additional deaths per 100 000 person-years. Significant heterogeneity was found among the different argentine provinces. The results indicate an uneven impact of the pan demic, with higher excess mortality rates in some re gions and more vulnerable age groups. These patterns suggest the need for differentiated strategies of health care response and support to the most vulnerable popu lations in scenarios of new epidemics.

Summary: The speciesSida cerradoensisKrapov. is reported for the first time for the Colombian flora, expanding its distribution to the northernmost limit known so far. This species can be recognized by the presence of: long, and retrorse-barbaded mericarp spines, purplish-red sepal lobes margin, irregularly dentate and purplish-red leafs margins, (9-)10-11 mericarps and verrucous stems. It is compared with other species of sect.Cordifoliaeocurring in the country.

ABSTRACT The ecology, distribution, and taxonomy of bopyrid isopod species are often omitted from studies not systematically addressed to crustaceans. From a wider study of zooplankton in coastal and reef waters of the Mexican Caribbean Sea, two bopyrid species were collected, Probopyrinella latreuticola, attached to the branchial chamber of Latreutes fucorum andProbopyrus pandalicola parasitizing the branchial chamber of Palaemon northropi. For both parasite-host associations, these records represent a new locality and the southernmost record in the Mexican Caribbean. A map and a list of the bopyrid species belonging to Bopyridae recorded in the Mexican Caribbean are provided.

Abstract The genus Isonychia groups mayflies with large nymphs present in lotic ecosystems. This genus has a very wide distribution, despite of this, in Mexico the records are very scarce and these do not refer to the environmental characteristics of the sites where they were found. The objective of this work is to report for the first time the genus Isonychia in Durango state, as well as to characterize some physicochemical parameters of water associated with its distribution. A total of 19 Isonychia nymphs, which probably correspond to the species I. sicca, were recorded in seven sites within the Nazas River basin. This extends the distribution range of the genus Isonychia for Mexico. The specimens were recorded in environments with moderate current speed and an acceptable water quality compared to other riparian systems, in terms of dissolved oxygen, electrical conductivity, total dissolved solids, pH, temperature and ammonium.

Resumen El género Isonychia agrupa efímeras con ninfas de gran tamaño presentes en ecosistemas lóticos. Este género tiene una distribución muy amplia, a pesar de ello, en México los registros son muy escasos y éstas no refieren las características ambientales de los sitios donde fueron encontradas. El objetivo de este trabajo es reportar por primera vez el género Isonychia en el estado de Durango, así como caracterizar algunos parámetros fisicoquímicos del agua asociados a su distribución. Se registraron 19 ninfas de Isonychia, que probablemente corresponden a la especie I. sicca, en siete sitios dentro de la cuenca del río Nazas. Esto amplía el rango de distribución del género Isonychia para México. Los ejemplares se registraron en ambientes con velocidad de corriente moderada y una calidad del agua aceptable en comparación con otros sistemas riparios, en términos de oxígeno disuelto, conductividad eléctrica, sólidos disueltos totales, pH, temperatura y amonio.

Abstract Introduction: The biological collections represent the foundation for the knowledge and management of the biodiversity of a region. However, regional collections focused on echinoderms are scarce in Mexico, particularly in the Central Mexican Pacific (CMP). The biological collection of the Laboratorio de Ecología Molecular, Microbiología y Taxonomía (LEMITAX) belongs to the Centro Universitario de Ciencias Biológicas y Agropecuarias of the Universidad de Guadalajara, Jalisco, Mexico and it aims to serve as a reference for the region’s marine biodiversity. Objective: To state the richness of echinoderms in the LEMITAX collection. Methods: The organisms deposited at the LEMITAX have been collected by SCUBA, free-diving, and bottom trawls with biological dredges in different areas of the Mexican Pacific. The specimens are wet-preserved (70 % ethanol; Asteroidea, Echinoidea, Holothuroidea, and Ophiuroidea) or dried (Asteroidea and Echinoidea). Results: The specimens are from the states of Sinaloa, Nayarit, Jalisco, and Colima, including two natural protected areas (NPAs), the Isabel Island National Park and the sanctuary of the Islands and Islets of Bahía de Chamela. The collection has 20 761 specimens of echinoderms distributed in 75 species (10 asteroids, 17 ophiuroids, 17 echinoids, and 31 holothuroids). The best-represented state is Jalisco (64 species), followed by Nayarit (31), Colima (20), and Sinaloa (11). Concerning the NPAs, Chamela is the best represented (60), followed by Isabel Island (22). Thirty-four new records are added; the largest contribution is for Chamela, with 14 new records, followed by the state of Jalisco (seven), Nayarit (four), Colima (three), and Isabel Island (three). For the CMP, the presence of Astropecten ornatissimus, Luidia phragma, Cucumaria crax, and Holothuria (Cystipus) casoae, is reported for the first time, updating the echinoderm richness to 197 species. The bathymetric distribution range of Ophiactis simplex, Ophiocomella alexandri, and Holothuria (Cystipus) casoae is extended, as well as the geographic range of Cucumaria crax. Conclusions: The biological collections deposited in the universities contribute substantially to the knowledge of biodiversity, as reflected in the LEMITAX collection, whose revision resulted in the updating of the echinoderm richness in the region.

Tiene como principal hospedador a equinos, por ende, esta garrapata adquiere importancia veterinaria por su rol como vector de microorganismos. Por lo antes mencionado, el objetivo del presente trabajo es aportar nuevos hallazgos de D. nitens para la provincia de Corrientes, Argentina ampliando así su distribución.

Abstract Echinodorus is the second largest genus of the aquatic plant family Alismataceae, comprising 28 species, of which 24 occur in Brazil. This study represents the first record of Echinodorus scaber Rataj for the State of Maranhão, based on material collected in the Municipality of Brejo, eastern Maranhão. Echinodorus scaber shares morphological similarities with E. macrophyllus (Kunth) Micheli, but it can be distinguished by (I) a highly branched inflorescence, (II) scabrous peduncles and petioles covered by stellate trichomes, and (II) small flowers with reflexed petals. This new record of E. scaber contributes to a better understanding of this genus’ diversity and distribution in Maranhão and underscores the necessity to broaden collection efforts for a better comprehension of the state’s flooded zones. Comprehensive collection efforts, with a special focus on aquatic plants and in locations far from the state’s main urban center, São Luís, may result in a significant knowledge increase of the flora, especially of the genus Echinodorus, which needs a broad taxonomic study. These recommendations may result in new records, range extensions, and species descriptions, contributing to the conservation of the aquatic environments of Maranhão.

Abstract Diseases in fish due to helminth parasites, especially Philometra species, are the primary worry in aquaculture. Philometra are responsible for health problem in fishes they directly affect fish growth and population parameters. A comprehensive survey was conducted involving the examination of the marine fish species Terapon jarbua, gathered from the coastal waters of Sindh, Pakistan In this research different Philometra species from marine fish Terapon jarbua during 2021 and 2022. Philometra nematodes, belonging to the family Philometridae, are common parasitic organisms inhabiting both marine and freshwater environments. Their prevalence, particularly when existing in high numbers within host organisms, can lead to severe and potentially lethal consequences. Employing light microscopy techniques, diverse species of Philometra were identified, including Philometra teraponi, P. jarbuai, P. arabiai, P. karachii, and P. awarii, localized primarily within the ovaries of the host fish. A total of 140 fish samples were examined and 76 were infected. The intensity of infected fish was 54.28%. The identification process encompassed meticulous analysis of crucial parameters, such as body size, esophagus length, positioning of the nerve ring, dimensions of the ventriculus, and ligament size. Intriguingly, the parasites were found in varying contexts; while some were free within the ovaries, others were embedded within tissues, inducing severe muscular dystrophy. This research presents novel findings of Philometra nematodes in the marine waters of Pakistan, extending their host and geographical distribution records. Future studies are needed to better evaluate and describe the dynamics and the epidemiology of Philometra infection in wild and cultured fish species aquaculture parameters Sindh 202 2022 Philometridae environments prevalence consequences techniques identified teraponi P jarbuai arabiai karachii awarii 14 7 5428 54 28 54.28% size length ring ventriculus Intriguingly contexts tissues dystrophy records 20 1 542 5 2 54.28 54.2 54.

Resumo Doenças em peixes causadas por parasitas helmintos, especialmente espécies de Philometra, são a principal preocupação na aquicultura. Philometra é responsável por problemas de saúde em peixes, pois afeta diretamente o crescimento destes e os parâmetros populacionais. Foi realizada uma pesquisa abrangente envolvendo o exame das espécies de peixes marinhos Terapon jarbua, coletadas nas águas costeiras de Sindh, Paquistão. Nesta pesquisa, foram identificadas diferentes espécies de Philometra em peixes marinhos Terapon jarbua durante 2021 e 2022. Nematoides Philometra, pertencentes à família Philometridae, são organismos parasitas comuns que habitam ambientes marinhos e de água doce. A sua prevalência, especialmente quando existe em grande número nos organismos hospedeiros, pode levar a consequências graves e potencialmente letais. Empregando técnicas de microscopia óptica, diversas espécies de Philometra foram identificadas, incluindo Philometra teraponi, P. jarbuai, P. arabiai, P. karachii e P. awarii, localizadas principalmente nos ovários do peixe hospedeiro. Um total de 140 amostras de peixes foram examinadas e 76 foram infectadas. A intensidade de peixes infectados foi de 54,28%. O processo de identificação envolveu análise meticulosa de parâmetros cruciais, como tamanho corporal, comprimento do esôfago, posicionamento do anel nervoso, dimensões do ventrículo e tamanho do ligamento. Curiosamente, os parasitas foram encontrados em contextos variados; enquanto alguns estavam livres nos ovários, outros estavam incorporados nos tecidos, induzindo distrofia muscular grave. Esta pesquisa apresenta novas descobertas de nematoides Philometra nas águas marinhas do Paquistão, ampliando seus registros de hospedeiros e distribuição geográfica.

ABSTRACT Objective: The aim of this study was to analyze the spatiotemporal evolution of the incidence rates of human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) in the state of Paraná, Brazil. Methods: An ecological study with an analytical component of time series analysis was conducted in the state of Paraná from 2007 to 2022. The data source was the Notifiable Diseases Information System. To study the trend, the Prais–Winsten generalized linear regression model was used by decomposing the time series, and for spatial analysis, the Moran's index was applied. Results: The total sample consisted of 50,676 HIV/AIDS records. The incidence rate showed an increasing trend, with an average growth of 2.14% [95% confidence interval – 95%CI 1.16–3.13] per month. From 2007 to 2014 and from 2015 to 2022, the average number of cases in the state was 105.64 and 159.20 per 100,000 inhabitants, respectively, with significant variation among municipalities. Spatial clusters of high risk persisted in the metropolitan region, the capital, and coastal areas, and a new cluster was observed in the northern region of the state. Conclusion: The incidence rates of HIV/AIDS showed an upward trend over time. The number of cases varied considerably in some municipalities, especially in the coastal region. Spatial analysis revealed geospatial patterns of high risk in the main metropolitan areas of Paraná: Curitiba (including the coastal area), Londrina, and Maringá, which share characteristics such as a high degree of urbanization and ongoing economic development.

Resultados: A amostra total foi composta de 50.676 registros de HIV/AIDS. A taxa de incidência apresentou tendência crescente, com crescimento médio de 2,14% (intervalo de confiança de 95% — IC95% 1,16–3,13) ao mês. Nos períodos de 2007 a 2014 e 2015 a 2022, a média de casos no estado foi de 105,64 e 159,20 a cada 100 mil habitantes, respectivamente, com importantes variações entre os municípios. Agrupamentos espaciais de alto risco permaneceram na região metropolitana à capital e litoral e um novo agrupamento foi observado à região norte do estado. Conclusão: As taxas de incidência do HIV/AIDS apresentaram tendência temporal crescente. O número de casos variou substancialmente em alguns municípios, principalmente naqueles localizados na região litorânea. A análise espacial revelou padrões geoespaciais de alto risco nas principais regiões metropolitanas do Paraná: Curitiba (abrange o litoral), Londrina e Maringá, as quais compartilham características como elevado grau de urbanização e constante desenvolvimento econômico.

ABSTRACT Changes in Neotropical bat taxonomy in the past two decades have caused significant shifts in our understanding of the diversity and distribution of the group. Taxonomic revisions have shown that the once widespread Platyrrhinus helleri (Peters, 1866) represented a species complex, which resulted in the elevation of Platyrrhinus helleri incarum (Thomas, 1912) to the species level for cis-Andean South America and the restriction of P. helleri to Central America and northern South America west of the Andes. Nevertheless, some studies still mention P. helleri for Brazil. Aiming to investigate if P. helleri occurs in Brazil, we collected specimens of small-sized Platyrrhinus in the Cerrado and Pantanal ecosystems, and revised vouchers in museum collections. Based on DNA sequence data and analysis of the pelage and craniodental morphology, we confirm that the only small Platyrrhinus species occurring in Cerrado and Pantanal of central Brazil corresponds to P. incarum. This is the first study to provide sequence data for Brazilian P. incarum. We also provide new records of P. incarum, extending its range by 390 km to southeast and 480 km to the east in Brazil. group Peters, Peters (Peters 1866 complex Thomas, Thomas (Thomas 1912 cisAndean cis Andean P Andes Nevertheless smallsized sized ecosystems collections morphology 39 48 186 191 3 4 18 19 1

Abstract This study presents a survey of small-stream fish species from the Purus-Madeira interfluve, collected in four streams near Humaitá on the highway BR-319. The results reveal a rich and diversified ichthyofauna with 3016 collected individuals distributed in 84 species, six orders, 25 families, and 60 genera. Of all the specimens collected, the Characiformes was the most representative, with eight families, 26 genera, and 42 species, followed Siluriformes, with nine families, 20 genera, and 23 species. In terms of families, Characidae had the highest number of species (25), followed by Loricariidae (9), and Cichlidae (8). Among the 95 captured species,s 11 are the first records for the region, evidencing a high diversity in these environments. Of the 84 species recorded in this study, 15 have not been assessed by the IUCN, while the remaining 62 include 23 listed as Least Concern (LC), three as data deficient (DD), and one as Near Threatened (NT). The southeastern Amazon region still has few fish surveys, especially in the region comprising the Purus-Madeira Interfluve, which highlights the importance of surveys to fill gaps and understand the biodiversity distribution patterns in the region. smallstream small stream PurusMadeira Purus Madeira interfluve BR319.

Resumo Este estudo apresenta um levantamento das espécies de peixes de pequenos riachos do interflúvio Purus-Madeira, coletadas em quatro riachos perto de Huimaitá na rodovia BR-319. Os resultados revelam uma ictiofauna rica e diversificada com 3016 indivíduos distribuídos em 84 espécies, seis ordens, 25 famílias e 60 gêneros. De todos os espécimes coletados, Characiformes foi a mais representativa, com oito famílias, 26 gêneros e 42 espécies, seguida da Siluriformes, com 9 famílias, 20 gêneros e 23 espécies. Em termos de famílias, Characidae apresentou o maior número de espécies (25), seguida de Loricariidae (9) e Cichlidae (8). Dentre as espécies capturadas, do total de 84 espécies, 11 são o primeiro registro da região, evidenciando uma alta diversidade nesses ambientes. Das 84 espécies registradas neste trabalho, 15 não foram avaliadas pela IUCN, 63 listadas como Menos Preocupante (LC), quatro como Deficientes em Dados (DD) e uma como Quase Ameaçada (NT). A região sudoeste da Amazônia ainda conta com poucos levantamentos de peixes, principalmente na região que compreende o Interflúvio Purus-Madeira, por isso é importante realizar levantamentos para preencher lacunas de coletas e compreender padrões de distribuição da biodiversidade da região.
