Impact of global change on the distribution of mountain mammals and birds
Conservation Biology, EarlyView.Abstract Climate change and land‐use changes are key drivers of global biodiversity loss. Many species are shifting to higher elevations or latitudes in response to global warming, often encountering unfavorable land‐use conditions during the shift. These changes can lead to reduced range size and increased extinction risks, particularly for mountain ...

, 2012 Teniendo como punto de partida la Convención de la Diversidad biológica de 1992, desde la segunda mitad del siglo XX las perspectivas en política y gestión medioambiental han dado un giro sin precedentes. Variables intangibles, difíciles de medir, como es la biodiversidad, son cada vez más importantes para la sociedad.

, 2009 The majority of forested area in Portugal was planted in 20th century. Extended plantations were performed with maritime pine and with the fast-growing exotic species Eucalyptus globulus make up a large proportion of the forest land (60%). Opinions differ as to the value of the new forests for biodiversity, but numerous studies have highlighted the ...

Identifying hotspots of faunal data deficiency to direct urgent research and monitoring
Conservation Biology, EarlyView.Abstract Data deficiency is a substantial challenge for extinction risk assessments because incomplete data means we cannot accurately identify priority protected areas for conservation. Here, we use the International Union for Conservation of Nature (IUCN) distributions of amphibians, sharks and rays, fish, mammals, birds, and reptiles to identify ...

Conservation Biology, EarlyView.Abstract Reversing ongoing biodiversity loss requires effectively managing anthropogenic threats. Although conservation actions can mitigate these threats, prioritizing and targeting such actions remain challenging because species respond differently depending on the nature of the threats and their biological traits.

, 2008 Este trabajo pretende actualizar el número de especies arbóreas y sus categorías taxonómicas subordinadas presentes en Misiones, en el marco de las últimas revisiones taxonómicas realizadas en el país. La valoración de la biodiversidad de cualquier componente boscoso, está estrechamente ligada a la ordenación forestal sustentable.
