Fitness consequences and ancestry loss in the Apennine brown bear after a simulated genetic rescue intervention

open access: yesConservation Biology, Volume 37, Issue 6, December 2023., 2023
Abstract Reduction in population size, with its predicted effects on population fitness, is the most alarming anthropogenic impact on endangered species. By introducing compatible individuals, genetic rescue (GR) is a promising but debated approach for reducing the genetic load unmasked by inbreeding and for restoring the fitness of declining ...

Sensitivity of tropical montane birds to anthropogenic disturbance and management strategies for their conservation in agricultural landscapes

open access: yesConservation Biology, Volume 37, Issue 6, December 2023., 2023
Abstract Tropical montane bird communities are hypothesized to be highly sensitive to anthropogenic disturbance because species are adapted to a narrow range of environmental conditions and display high rates of endemism. We assessed avian sensitivity at regional and continental scales for a global epicenter of montane bird biodiversity, the tropical ...

Identifying Mozambique's most critical areas for plant conservation: An evaluation of protected areas and Important Plant Areas

open access: yesBiotropica, Volume 55, Issue 6, Page 1183-1194, November 2023., 2023
Plants are often overlooked in conservation planning. In Mozambique, we find that the richest areas for rare and threatened plant species are poorly represented within the protected area network. We use Important Plant Areas and the Weighted Endemism including Global Endangerment (WEGE) index to identify opportunities to better conserve Mozambique's ...

Population status of the world's largest limpet, Scutellastra mexicana (Mollusca: Patellidae), on María Madre Island, Mexico: Possible last bastion of a species facing global extinction

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 33, Issue 10, Page 1049-1060, October 2023., 2023
Abstract Scutellastra mexicana is the largest patellid in the world, with records of up to 35.5 cm in length, and is one of the most endangered marine invertebrates from tropical Pacific rocky shores. The decline of this species occurred during the 20th century, when fishing cooperatives reported the capture of millions of specimens in less than 2 ...
