Copy Number Variation Regions Differing in Segregation Patterns Span Different Sets of Genes
Animals, 2023 Copy number variations regions (CNVRs) can be classified either as segregating, when found in both parents, and offspring, or non-segregating. A total of 65 segregating and 31 non-segregating CNVRs identified in at least 10 individuals within a dense ...

Advancing conservation breeding programs for marine invertebrates
Conservation Biology, EarlyView.Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

Translocation effects on regional and local population viability and connectivity
Conservation Biology, EarlyView.Abstract Translocations and reintroductions aim to improve the viability of isolated populations and promote connectivity for large carnivores. However, there is no established framework for assessing their success. We used the Eurasian lynx (Lynx lynx) in western and central Europe to assess the impact of translocations on the viability of six ...

Contrasting mechanisms driving the northward expansion of African raptors in Europe
Journal of Zoology, EarlyView.Recent climate warming and landscape changes are enabling African raptors to reach Europe through contrasting mechanisms. Using species distribution models, we show that the Atlas Long‐legged Buzzard expands northward following climatic suitability, whereas African vultures reach Europe despite low climatic favourability through socially mediated ...
