Enhanced fish detection sensitivity in aquatic systems using environmental RNA

Methods in Ecology and Evolution, EarlyView.
Abstract Environmental RNA (eRNA) can potentially augment the biological monitoring ability of the established environmental DNA (eDNA) application in conservation. Despite faster degradation, environmental RNA could offer unique advantages: it may help reduce the legacy signal compared to eDNA, provide insights into physiological status through gene ...

Impacts of weather events on the effectiveness of climate adaptation interventions for threatened species

Conservation Biology, EarlyView.
Abstract Climate change is driving increasingly frequent and severe weather events that can undermine the effectiveness of conservation interventions for threatened species, yet the extent and mechanisms of such impacts remain poorly understood. We assessed both peer‐reviewed and gray literature to determine how climate adaptation interventions have ...

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
