Confirmed Outbreaks of Streptococcosis Caused by Streptococcus agalactiae Serotype Ia in Nile Tilapia Culture From Campeche, MexicoNARA Subscribed
Streptococcus agalactiae was confirmed as the etiologic agent of streptococcosis in Nile tilapia ( Oreochromis niloticus ) from Campeche, Mexico, during a cross‐sectional investigation of eight semi‐intensive farms (2021–2022) that yielded virulent strains in a challenge assay. Standard bacteriology, histopathology, API‐20 Strep phenotyping, one‐step PCR, and real‐time PCR confirmed S. agalactiae in five farms (62.5%). Gross a...
Farming-associated variation in chytrid infection and shedding dynamics in invasive American bullfrogsNARA Subscribed
The global amphibian decline caused by the chytrid fungus Batrachochytrium dendrobatidis (Bd) threatens biodiversity. Some species, such as the bullfrog ( Aquarana catesbeiana ), can persist with infection without overt disease, yet the processes underlying this response remain unclear. Because bullfrogs are farmed worldwide under high-density conditions, understanding how production environments influence infection dynamics a...
Interpretable deep learning reveals spatiotemporal MRI features of brain aging that align with neurodegenerationNARA Subscribed
Cortical thinning and atrophy are hallmarks of brain aging that have been characterized using magnetic resonance imaging (MRI). Brain aging involves many neuroanatomic features whose effects on brain structure remain unexplored. To address this challenge, we trained interpretable deep neural networks (DNNs) to estimate brain age (BA) from T 1 -weighted ( T 1 w) MRI. By identifying MRI features unapparent to humans, DNNs can fi...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
A new gecko (Phyllodactylidae: Homonota whitii group) from the Diaguita highlands, Argentina, with an updated phylogeny for the genusNARA Subscribed
The South American Transition Zone (SATZ) connects the Neotropical and Andean regions, stretching from western Venezuela to northern Chile and central‐western Argentina. In Argentina, the northwestern Altoandina Cuyana province includes arid and semi‐arid ecosystems, particularly the Diaguita District, spanning Catamarca, La Rioja and northern San Juan. This mountainous region, including the Sierra de Famatina and Cordillera F...
Our primary objective was to compile a comprehensive dataset on bird–window collisions throughout the Neotropical region, including both published and unpublished sources. On May 12, 2020, we extensively disseminated invitations to provide data via email and social media platforms. By providing a template worksheet, we required standardized information from collaborators to complete and register their data. To better understan...
Whale carcasses create habitats in the deep sea which are colonized by organisms related to other chemosynthetic environments suggesting that whale falls may act as intermediate refugia for the dispersal and evolution of deep-sea organisms. Such evidence comes mainly from macrofaunal organisms whereas for the smaller meiofauna, data on whalebone assemblages is lacking. In this study, we investigated nematode colonization of wh...
AMAZONIA CAMTRAP: A data set of mammal, bird, and reptile species recorded with camera traps in the Amazon forestNARA Subscribed
The Amazon forest has the highest biodiversity on Earth. However, information on Amazonian vertebrate diversity is still deficient and scattered across the published, peer‐reviewed, and gray literature and in unpublished raw data. Camera traps are an effective non‐invasive method of surveying vertebrates, applicable to different scales of time and space. In this study, we organized and standardized camera trap records from dif...
