Genetic origins and climate‐induced erosion in economically important Asian walnuts
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract The global climate is undergoing unprecedented changes, posing significant threats to species persistence. However, the spatiotemporal impacts on genetic diversity remain poorly understood, hindering species conservation and management. Walnuts, generally referred to as Juglans regia and J. sigillata, are economically vital in Asia, but little

Poliformismo isoenzimático de seis poblaciones naturales de Raigrás inglés de Galicia
Pastos, 2011 El polimorfismo de siete sistemas isoenzimáticos (PGI, GOT, ACP, PGM, 6-PGD, SHDH y EST) se ha estudiado en seis poblaciones naturales de Lolium perenne representativas de dos grupos clasificados de acuerdo con características agronómicas, con objeto de comparar la adecuación entre la clasificación agronómica y otros parámetros de variabilidad genética.

Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Spatial segregation in at‐sea distribution is frequently observed in seabirds and can have important implications for conservation and management. Globally, many albatross and petrel populations are declining due to bycatch in fisheries. In South Georgia, the decrease in wandering albatrosses (Diomedea exulans) differs among breeding sites ...

Detecting mass mortality events in wildlife populations
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Reports in the literature of mass mortality events (MMEs) involving diverse animal taxa are increasing. Yet, many likely go unobserved due to imperfect detection and infrequent sampling. MMEs involving small, cryptic species, for instance, can be difficult to detect even during the event, and degradation and scavenging of carcasses can make ...

Evolution of research on global amphibian declines
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract In the late 1980s, the scientific community became aware of severe, enigmatic amphibian population declines. These declines triggered a wave of research focused on quantifying their extent and identifying key drivers. We used text‐analysis techniques, including topic modeling and geoparsing, to examine the evolution of research focused on ...
