Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal

Conservation Biology, EarlyView.
Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...

Evaluación del efecto de las temperaturas de almacenamiento sobre los parámetros de vigor en semillas de Neltuma caldenia Burkart

Ab Intus
Los bosques de "caldén" en el Distrito del Caldén, región fitogeográfica del Espinal, se encuentran muy modificados por el efecto de la explotación forestal, desmontes, incendios y el pastoreo excesivo.

To release or not to release? A call for caution when considering wildlife reintroductions

Conservation Science and Practice, EarlyView.
Conservation efforts often focus on flagship species and short‐term measures such as captive breeding and reintroductions, yet these approaches may benefit from being complemented with a broader view of the factors that influence long‐term recovery. Using examples from management programs in the Iberian Peninsula, we highlight the value of considering ...

Employing a Hysteresis Approach to Analyze Shifts in Tree Physiological Thresholds in Response to Drought

Plant, Cell &Environment, EarlyView.
ABSTRACT Drought‐induced tree mortality underscores the need for improved physiological models to predict tree responses to water stress. We employed a hysteresis modelling approach analyzing diel water absorption and desorption cycles to understand drought‐induced shifts in physiological thresholds.

Differences in characteristics between naturalized threatened plants and other threatened plants

Conservation Biology, Volume 40, Issue 3, June 2026.
Abstract Many non‐native plant species introduced by humans have become naturalized. At the same time many species are threatened in their native range. However, the number of plant species threatened in their native range that are naturalized elsewhere remains unknown.

Los jardines botánicos y la crisis de la biodiversidad

Botan‪ical Sciences, 2013
Históricamente, los jardines botánicos se enfocaban sobre especies con interés económico, y no había mención alguna de la conservación hasta mediados del siglo XX. La destrucción de las selvas y bosques, pérdida de biodiversidad y el cambio climático son
