Distinct mtDNA lineages in free-ranging Ammotragus(aoudad) from the United States indicate multiple introductions from northern Africa. [PDF]
Ecol Evol, 2022 This manuscript explains that human‐mediated translocations of aoudad into the United States were a result of multiple introductions with putative subspecies identification as A. l. sahariensis and/or A. l. blainei and A. l. lervia. Two major clades were identified using phylogenetic, network, and divergence analyses, in which genetic distances ranged ...

Assessing the levels of intraspecific admixture and interspecific hybridization in Iberian wild goats (Capra pyrenaica). [PDF]
Evol Appl, 2021 Abstract Iberian wild goats (Capra pyrenaica, also known as Iberian ibex, Spanish ibex, and Spanish wild goat) underwent strong genetic bottlenecks during the 19th and 20th centuries due to overhunting and habitat destruction. From the 1970s to 1990s, augmentation translocations were frequently carried out to restock Iberian wild goat populations (very

Population growth lags in introduced species. [PDF]
Ecol Evol, 2021 Abstract When introduced to new ecosystems, species' populations often grow immediately postrelease. Some introduced species, however, maintain a low population size for years or decades before sudden, rapid population growth is observed. Because exponential population growth always starts slowly, it can be difficult to distinguish species experiencing

Pedigree analysis in the mhorr gazelle (Nanger dama mhorr): Genetic variability evolution of the captive population. [PDF]
Ecol EvolThis paper describes the genetic characterization of the mhorr gazelle population in captivity obtained through pedigree analysis. The genetic variability evolution shows how the mating strategy used has allowed maximizing the genetic potential of the population despite the low number of founders.

Microscopy Research and Technique, Volume 86, Issue 9, Page 1206-1233, September 2023., 2023 Exploring the Vomeronasal Organ in the Dama Gazelle, an Endangered Mammal Abstract Dama gazelle is a threatened and rarely studied species found primarily in northern Africa. Human pressure has depleted the dama gazelle population from tens of thousands to a few hundred individuals.

Molecular Ecology, Volume 31, Issue 18, Page 4593-4606, September 2022., 2022 Abstract Host‐specialist parasites of endangered large vertebrates are in many cases more endangered than their hosts. In particular, low host population densities and reduced among‐host transmission rates are expected to lead to inbreeding within parasite infrapopulations living on single host individuals. Furthermore, spatial population structures of

Oikos, Volume 2022, Issue 8, August 2022., 2022 Despite its recognized importance for understanding the evolution of animal sociality as well as for conservation, long term analysis of social networks of animal populations is still relatively uncommon. We investigated social network dynamics in males of a gregarious mountain ungulate (Alpine ibex, Capra ibex) over ten years focusing on groups, sub ...

Molecular Ecology, Volume 31, Issue 13, Page 3548-3565, July 2022., 2022 Abstract Population bottlenecks can have dramatic consequences for the health and long‐term survival of a species. Understanding of historic population size and standing genetic variation prior to a contraction allows estimating the impact of a bottleneck on the species' genetic diversity.

Review of European, Comparative &International Environmental Law, Volume 31, Issue 2, Page 182-198, July 2022., 2022 Abstract Restoring functional ecosystems in Europe inter alia requires restoring large mammal (megafauna) diversity and densities to levels well above the current downgraded state, which results from a human‐driven wave of megafauna extinctions and extirpations in the Late Pleistocene and Holocene.

Sex‐specific inbreeding depression: A meta‐analysis
Ecology Letters, Volume 25, Issue 4, Page 1009-1026, April 2022., 2022 Our meta‐analysis across experimental studies found evidence for general inbreeding depression for both males and females and, although the difference between the sexes was not substantial, females were slightly more sensitive to inbreeding depression than males.
