We examined whether occupancy and abundance models provided consistent threat status. Occupancy and abundance data suggested declines for the study species in the study area, but occupancy generally showed smaller proportional changes compared with abundance data. Leer más.
A pressing issue in historical biogeography for clades with long evolutionary histories and intercontinental distributions is the ever-changing position of tectonic plates. Over time, this shifting alters the proximity between areas, a factor that very few models can easily account. In addition, the absence of fossils from most molecular phylogenies often erases biogeographic signals not retained in trees of extant taxa. Leer más.
Ranaviruses pose major threats to biodiversity and human livelihoods, with mass mortalities and population collapse following disease outbreaks in both wild and farmed animals. This has led to all amphibian-infecting ranaviruses and Ranavirus perca1 in fish being included on the list of notifiable agents by the World Organization for Animal Health (WOAH). Leer más.

This review highlights the need for noninvasive sampling methods and long-term monitoring to guide conservation strategies and assess ecosystem and turtle health. Freshwater chelonians remain essential for understanding contamination dynamics and mitigating environmental degradation in aquatic habitats. Leer más.
