Potential Adaptive Introgression From Dogs in Iberian Grey Wolves (Canis lupus)
Molecular Ecology, Volume 34, Issue 12, June 2025.ABSTRACT Invading species along with increased anthropogenization may lead to hybridization events between wild species and closely related domesticates. As a consequence, wild species may carry introgressed alleles from domestic species, which is generally assumed to yield adverse effects in wild populations.

Ecology and Evolution, Volume 15, Issue 5, May 2025.We aim to uncover the current and historic effective dispersal distances and characterize fine‐scale genetic structure in the forest tree species Nothofagus pumilio. Short seed dispersal distances mean N. pumilio distribution expansion capacity may be limited, especially in the context of global change.

Delineating ecologically distinct groups for annual cycle management of a declining shorebird
Journal of Applied Ecology, Volume 62, Issue 5, Page 1152-1165, May 2025.Using measurements of migratory connectivity in concert with expert opinion can define ecologically distinct groups for wildlife management that differ in the environmental conditions they experience across seasons of the annual cycle, which is a key component for understanding and reversing declines of migratory species. Abstract Patterns of migratory

Island restoration to rebuild seabird populations and amplify coral reef functioning
Conservation Biology, Volume 39, Issue 1, February 2025.Abstract Mobile organisms like seabirds can provide important nutrient flows between ecosystems, but this connectivity has been interrupted by the degradation of island ecosystems. Island restoration (via invasive species eradications and the restoration of native vegetation) can reestablish seabird populations and their nutrient transfers between ...

Integrating adult occurrence and reproduction data to identify conservation measures for amphibians
Conservation Biology, Volume 39, Issue 1, February 2025.Abstract Monitoring programs are pivotal to establishing sound management. Due to economic, logistic, and time limitations, monitoring programs often overlook differences among life‐history stages. However, species occurrence does not necessarily mean population viability, and it is unclear to what extent monitoring programs that do not consider ...

Conservation Biology, Volume 39, Issue 1, February 2025.Abstract Biodiversity is critical for maintaining ecosystem function but is threatened by increasing anthropogenic pressures. In the Southern Ocean, a highly biologically productive region containing many endemic species, proactive management is urgently needed to mitigate increasing pressures from fishing, climate change, and tourism.

The Journal of Latin American and Caribbean Anthropology, Volume 29, Issue 4, Page 352-363, December 2024.Abstract This paper explores selective aspects of the historical processes of organization of the kichwa peasantry in the Andes of Ecuador. Based on the analysis of two representative cases of confrontation between peasants and landowners over access to land in the province of Chimborazo, it discusses the relevance of the concept of “gamonalismo” as ...
