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

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 ...

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 ...

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 ...

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 ...

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.

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 ...

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.
