Invasoras
Muchas especies introducidas en nuevos entornos no pueden sobrevivir en su nuevo entorno. Sin embargo, un porcentaje de estas especies pueden expandir el área que infestan e impactar negativamente la economía, la salud humana o la ecología de una región, las cuales se denominan invasoras. La alteración del hábitat y los impactos de las especies invasoras han sido la principal causa de extinción de especies en los últimos cientos de años, aumentando la tasa de extinción en aproximadamente un 1000 por ciento. Aunque en el pasado, muchas de estas pérdidas no se registraron, en la actualidad, existe una comprensión cada vez mayor de los costos ecológicos de la invasión biológica en términos de pérdida irrecuperable de la biodiversidad nativa y degradación del funcionamiento de los ecosistemas. Si bien las causas subyacentes de las amenazas de las especies invasoras son importantes y de naturaleza global, estas amenazas se pueden abordar de manera eficaz mediante esfuerzos de colaboración a nivel regional y local, en especial mediante la prevención, la detección temprana y la respuesta rápida.

5 July 2017 - Removing the flowers of an invasive shrub from mosquito-prone areas might be a simple way to help reduce malaria transmission, according to anew study published in the open access Malaria Journal.Removing the flowers from villages in Mali decreased the local mosquito vector...
- Of all the ways that have been tried to control malaria, one of the easiest could also be among the most effective, a new study suggests. Yet the idea of cutting back on the regular food supply of mosquitoes has been neglected, possibly because it just seemed too simple to work. Malaria is...

Abstract, Transactions of the Royal Society of South Africa, 2018 With a few exceptions, comprehensive lists of alien plants that invade natural ecosystems are lacking in sub-Saharan Africa. Some available lists are either preliminary or localised, or focus on agricultural weeds. This study set...
- Developing countries, with high dependence on natural resources and some of the last remaining biodiversity hotspots, are especially vulnerable to weed destruction. The IPM Innovation Lab, recognizing the current and future threat, has helped secure permits to introduce biological control against...
