Global threats from invasive alien species in the twenty-first century and national response capacities

Publicado on Mié, 24 Ago 2016, 11:26

Invasive alien species (IAS) threaten human livelihoods and biodiversity globally. Increasing globalization facilitates IAS arrival, and environmental changes, including climate change, facilitate IAS establishment. Here we provide the first global, spatial analysis of the terrestrial threat from IAS in light of twenty-first century globalization and environmental change, and evaluate national capacities to prevent and manage species invasions. We find that one-sixth of the global land surface is highly vulnerable to invasion, including substantial areas in developing economies and biodiversity hotspots. The dominant invasion vectors differ between high-income countries (imports, particularly of plants and pets) and low-income countries (air travel). Uniting ...

Scientists gear up to battle invasive species

Publicado on Mié, 24 Ago 2016, 08:34

A research programme to tackle invasive species that kill plants and sicken animals is getting under way at the United Kingdom’s Centre for Agriculture and Bioscience International (CABI). The programme, worth US$50 million, aims to find scientific solution that help farmers to either defeat or adapt to the presence of invasive species. The goal is to tackle the devastating economic impact of such species, estimated to be around $183 billion in lost crops and revenue in Sub-Saharan Africa, South Asia and South-East Asia every year.

Amenazas de especies invasoras: causa de extinción de las plantas

Publicado on Mar, 10 May 2016, 18:04

Una quinta parte de las especies vegetales del mundo corre peligro de extinción, advirtieron unos investigadores británicos este martes en un censo mundial sin precedentes del reino vegetal. El estudio de la organización británica Royal Botanic Gardens, Kew, de Londres, indica que el 21% de las especies vegetales están en peligro. Este informe, el primero de su tipo, pretende convertirse en un punto de referencia mundial para el estudio de las plantas.

El estudio, que estima que hay un total de 390,900 plantas conocidas para la ciencia, observó que la agricultura representa la mayor amenaza de extinción. La tala ...
