Spatial segregation and bycatch risk as potential drivers of population trends of wandering albatrosses at South Georgia

open access: yesConservation 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

open access: yesConservation 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

open access: yesConservation 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 ...

Vulnerability of marine megafauna to global at‐sea anthropogenic threats

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

Extent of threats to marine fish from the online aquarium trade in the United States

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
The global marine aquarium hobby is a multibillion‐dollar industry, largely driven by demand from the United States. Much of this trade occurs online. We web scraped 4 major US‐based e‐commerce platforms selling marine aquarium fish to determine the retail price and source (wild capture, aquaculture, or both) of 13 families of ray‐finned marine fish ...

Understanding key population drivers of the spotted wing Drosophila in cultivated and natural areas in the Andes

open access: yesScientific Reports
The spotted-wing drosophila (SWD), Drosophila suzukii (Matsumara) (Diptera: Drosophilidae), is a serious global pest. Understanding the drivers for its success is fundamental to develop sustainable management tools.
