Aim Invasive alien species (IAS) can cause profound impacts on ecosystem function and diversity, human health, well-being livelihoods. Climate change is an important driver of biological invasions, so it critical to develop models climate-driven scenarios IAS range shifts establish preventive measures. In this study, we analyse how projected changes in the frequency magnitude climate extreme ev...

The taxonomic status of Forbes' parakeet has remained unresolved for several decades. With the advent of modern molecular biological techniques, it has become possible to augment traditional taxonomic practices (i.e. those based on morphology) with DNA data analysis. The conservation status of Forbes' parakeet (presently listed by as "critically threatened") warrants urgent research into its ge...

Researcher William Haseltine, head of Human Genome Sciences Inc. in Rockville, Maryland, likes to claim that knowledge from the human genome, combined with a few technology breakthroughs, will someday enable humans to live forever. Most researchers who study aging have more modest expectations--for example, trolling the genome for new insights into genes involved in so-called oxidative damage t...

The complete genome sequence of a virulent Newcastle disease virus (vNDV) strain isolated from an exotic parakeet (Melopsittacus undulatus) is described here. The virulent strain parakeet/Pak/R-Pindi/SFR-16/2016 was isolated from a bird reared as a pet in the province of Punjab in the northern region of Pakistan in 2016. Phylogenetic analysis classified the isolate as a member of NDV class II, ...

In general, non-native bird species may competitively exclude native species from nest sites. The potential resource conflict between a native and an introduced bird species, the native European Starling (Sturnus vulgaris) and the introduced Asian Ring-necked Parakeet (Psittacula krameri), was inferred from hole occupancy in parks of the German Upper Rhine Valley (Wiesbaden, Mannheim, Schwetzin...
