The high Andes, gene flow and a stable hybrid zone shape the genetic structure of a wide-ranging South American parrot

Abstract Background While the gene flow in some organisms is strongly affected by physical barriers and geographical distance, other highly mobile species are able to overcome such constraints.In southern South America, the Andes (here up to 6,900 m) may constitute a formidable barrier to dispersal.In addition, this region was affected by cycles of

Exposure of insects to current use pesticide residues in soil and vegetation along spatial and temporal distribution in agricultural sites

Abstract Current use pesticides (CUPs) are recognised as the largest deliberate input of bioactive substances into terrestrial ecosystems and one of the main factors responsible for the current decline in insects in agricultural areas.To quantify seasonal insect exposure in the landscape at a regional scale (Rhineland-Palatine Flood Free Inlet Hose
