Samuel C. Gomides, Talita M. Machado, Jôine C. Evangelista‐Vale, Angele Tatiane Martins‐Oliveira, more

Conservation Biology > 35 > 6 > 1821 - 1832

The reintroduction of a species that is extinct in the wild demands caution because reintroduction locations may be associated with threats, such as hunting, poor‐quality habitat, and climate change. This is the case for Cyanopsitta spixii (Spix's Macaw), which has been extinct in the wild since 2000. The few living individuals were created in captivity and will be used in a reintroduction project...

P. J. Taillie, S. R. Jolly, L. R. Bobay, S. Sneckenberger, more

Animal Conservation > 24 > 2 > 280 - 290

Wildlife is increasingly threatened by a suite of anthropogenic factors including climate change, habitat loss from human development, and invasive species. These threats are particularly pronounced on islands where species are more likely to go extinct. To better understand how native and invasive species on islands might respond to these threats, we compared habitat use between the endangered silver...

Barn owls as biological control agents: potential risks to non‐target rare and endangered species

M. Zaitzove ‐ Raz, O. Comay, Y. Motro, T. Dayan

Animal Conservation > 23 > 6 > 646 - 659

Rodent agricultural pests cause significant food loss every year. Attempts at mitigation via chemical pest control may cause secondary poisoning and harm non‐target species. Biological pest control by bolstering barn owl Tyto alba populations through the provision of artificial nest boxes is in use in several countries. The national biological pest control project of Israel began in the early 1980s...

Tirupathi Rao Golla, Leishe Pieterse, Candice M. Jooste, Peter R. Teske

Diversity and Distributions > 26 > 12 > 1825 - 1832

Aim Biogeographical transition zones are areas of overlap between the faunas of adjacent biogeographical entities. Particularly the well‐defined transition zones along linear coastlines are interesting natural laboratories to study dispersal and incipient speciation. Few studies have explored whether marine biogeographical transition zones harbour biodiversity that is distinct from that of the biogeographical...

Snapshot isolation and isolation history challenge the analogy between mountains and islands used to understand endemism

Suzette G. A. Flantua, Davnah Payne, Michael K. Borregaard, Carl Beierkuhnlein, more

Global Ecology and Biogeography > 29 > 10 > 1651 - 1673

Aim Mountains and islands are both well known for their high endemism. To explain this similarity, parallels have been drawn between the insularity of “true islands” (land surrounded by water) and the isolation of habitats within mountains (so‐called “mountain islands”). However, parallels rarely go much beyond the observation that mountaintops are isolated from one another, as are true islands....
