Evaluating the use of taxonomy in the IUCN Red List

Conservation Biology, EarlyView.
Abstract Taxonomy defines the units that conservationists strive to preserve for future generations. However, the discovery of new species and the taxonomic revision of existing species affect conservation efforts. Despite the importance of taxonomy for a species’ conservation, there is currently no overview of how those leading species extinction risk

Behavioral interventions to reduce demand for threatened freshwater turtles as pets

Conservation Biology, EarlyView.
Abstract Growing demand for freshwater turtles as pets has fueled illegal trade and accelerated wild population declines, underscoring the need for theory‐based demand‐reduction interventions. We conducted a three‐part randomized controlled trial with active turtle keepers (n = 1800) in China to test conservation‐ and legality‐framed messages by ...

Impact of global change on the distribution of mountain mammals and birds

Conservation Biology, EarlyView.
Abstract Climate change and land‐use changes are key drivers of global biodiversity loss. Many species are shifting to higher elevations or latitudes in response to global warming, often encountering unfavorable land‐use conditions during the shift. These changes can lead to reduced range size and increased extinction risks, particularly for mountain ...

Identifying hotspots of faunal data deficiency to direct urgent research and monitoring

Conservation Biology, EarlyView.
Abstract Data deficiency is a substantial challenge for extinction risk assessments because incomplete data means we cannot accurately identify priority protected areas for conservation. Here, we use the International Union for Conservation of Nature (IUCN) distributions of amphibians, sharks and rays, fish, mammals, birds, and reptiles to identify ...

Reaparición de una especie que se creía extinta: nuevos registros del tucán grande (Ramphastos toco) en la provincia de Tucumán, Argentina

Acta Zoológica Lilloana, 2011
El Tucán Grande (Ramphastos toco Statius Müller, 1776) se distribuye en selvas y bosques del Norte Argentino. Es una especie muy buscada como mascota, lo que sumado a la pérdida de hábitat, está provocando su disminución numérica.

Insights from three decades of IUCN Red List assessments catalyzing shark, ray, and chimaera conservation

Conservation Biology, EarlyView.
Abstract The International Union for Conservation of Nature (IUCN) Red List of Threatened Species is a critical measure of global aquatic and terrestrial biodiversity status. It is also the basis for the Red List Index, which tracks extinction risk over time.

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.
