Genomics‐informed management of ex situ populations

Conservation Biology, EarlyView.
Abstract The European Association of Zoos and Aquariums (EAZA) manages insurance populations for hundreds of species through its EAZA ex situ programs (EEPs). EEPs help safeguard against extinction in the wild and provide source populations for genetic rescue programs.

A framework to assess trajectories of societal and biological extinction

Conservation Biology, EarlyView.
Abstract Threatened species that are societally extinct, which refers to the loss of a species’ presence in human societies, are less likely to receive conservation attention, potentially resulting in their biological extinction going unnoticed. However, little is known about the process and forms of such extinction.

A systematic review of deforestation outcomes in potential other effective area‐based conservation measures across Latin America

Conservation Biology, EarlyView.
Abstract Recognizing conservation contributions from areas outside protected areas (PAs), including other effective area‐based conservation measures (OECMs), is increasingly central to meeting global biodiversity targets. However, little is known about which areas could qualify as OECMs and whether they support forest conservation.

An update on hatchery success of olive ridley turtles (Lepidochelys olivacea) at Playa San Miguel, Costa Rica

Conservation Science and Practice, EarlyView.
This study aims to elucidate and update the impacts of nest temperatures and rainfall on the San Miguel olive ridley hatchery success from 2019 to 2022 sea turtle seasons. Nest sand temperatures significantly affect nest failures (Estimate = 0.123 ± 0.059 SE, z = 2.088, p = .037) while nesting seasons also significantly affect nest failures with lower ...

Embryonic and larval development of the endangered Chiapas killifish Tlaloc hildebrandi (Cyprinodontiformes: Profundulidae)

Journal of Fish Biology, EarlyView.
Abstract The early ontogeny of endemic freshwater fishes provides essential baseline biological information for conservation and management, particularly in species with restricted distributions and high vulnerability to habitat degradation, environmental change and population decline. This study presents the first detailed description of embryonic and

Subsistence hunting shapes the spatial variation of jaguar densities in community‐managed forests

Journal of Zoology, EarlyView.
Jaguars and people can coexist in community‐managed forests, but distance matters. In Guatemala's Maya Biosphere Reserve, jaguar numbers increased markedly in areas harder to reach on foot, yet jaguars were still found near communities, showing that responsibly managed forests can support jaguar populations while allowing people to maintain traditional

Evolutionary history and taxonomy of the genus Zea

American Journal of Botany, Volume 113, Issue 10, October 2026.
Abstract Premise Taxonomic differentiation of teosinte species (Zea spp.), the closest relatives of maize (Z. mays) is crucial for understanding their distribution, ecology, and evolutionary history. Resolving the taxonomic uncertainties is of scientific interest and has practical implications for biodiversity management, preservation, and utilization.
