A study led by the Doñana Biological Station reveals that species richness and diversity of ants and bees could increase after a wildfire. Some of these positive effects could persist over the long term.

An international scientific team led by the CSIC cuantifies the effects of the invasion of these insects in agriculture and public health
This work takes data from Invacost, the first database that compiles economic costs associated with biological invasions worldwide.

A scientific team at the Doñana Biological Station – CSIC studied the competitive interactions between several ant communities in three different habitats in Doñana.

Invasive species have major impacts on biodiversity and are one of the primary causes of amphibian decline and extinction. Unlike other top ant invaders that negatively affect larger fauna via chemical defensive compounds, the Argentine ant (Linepithema humile) does not have a functional sting. Nonetheless, it deploys defensive compounds against competitors and adversaries. Levels of ant aggression toward 3 native terrestrial amphibians were estimated by challenging juveniles in field ant...

The consequences of ant invasions on ecosystems may only become apparent after long periods. In addition, predicting how sensitive native fauna will respond is only possible if the underlying proximate mechanisms of their impact are identified. The attraction of the native and invasive ant community to artificial bird nests was studied, together with reproduction of a wild native songbird over five consecutive breeding seasons in relation to the presence of an invasive ant species. Biometric,...
