First national assessment of wildlife mortality in Ecuador: An effort from citizens and academia to collect roadkill data at country scale. [PDF]

Ecol Evol, 2023
The first national assessment of wildlife mortality caused by road traffic in Ecuador. A comprehensive roadkill dataset with more than 5000 roadkill records in Ecuador that includes threatened and poorly known species. A joint effort of citizens and academia to collect roadkill data at a country scale.

Wintering Together: Do Migrants Impact Residents? A Literature Review. [PDF]

Ecol Evol
This review examines the overlooked impacts of interspecific competition on resident tropical birds during the overwintering period, highlighting the need for a deeper understanding of their interactions with migratory species. By evaluating the literature through the lens of competition theory, we identify critical gaps in knowledge and suggest that ...

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

Conservation 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

Conservation 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

Biotropica, 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

Aquatic 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 ...

Repeated asynchronous evolution of single‐species endemics of ivies (Hedera L.) in Macaronesian archipelagos

Journal of Biogeography, Volume 50, Issue 10, Page 1763-1777, October 2023., 2023
Abstract Aim Evolutionary studies of oceanic island endemics are usually focused on lineages that have experienced in situ radiation, while those that speciated once on the island or archipelago but have not further diversified (single‐species endemics) remain understudied.

Neutral‐based processes overrule niche‐based processes in shaping tropical montane orchid communities across spatial scales

Journal of Ecology, Volume 111, Issue 8, Page 1614-1628, August 2023., 2023
High compositional turnover, even across habitats with the highest degree of human intervention, suggests that both forest‐dwelling and open‐habitat species do not easily disperse across habitats. Species dispersal is the major force of orchid community turnover and might be strongly dependent upon macroevolutionary processes and species life‐history ...

Chilean bee diversity: Contrasting patterns of species and phylogenetic turnover along a large‐scale ecological gradient

Ecosphere, Volume 14, Issue 5, May 2023., 2023
Abstract Chile's isolation and varied climates have driven the evolution of a unique biodiversity with a high degree of endemism. As a result, Chile encompasses diverse environments, including the Mediterranean‐type ecosystem, a global biodiversity hotspot.

Patrones de distribución y zonas prioritarias para la conservación de la avifauna de la costa del Pacífico de Guerrero, México

Revista Mexicana de Biodiversidad, 2017
Se modelaron las condiciones de idoneidad ambiental asociada a la presencia de 370 especies de aves en la costa del Pacífico del estado de Guerrero. Con estos modelos se obtuvieron los patrones de riqueza, de endemismo y de acumulación de especies de ...
