(Mal)adaptation in exotic parakeets

In this network funded by COST (European Commision  + European Science Foundation), I co-coordinate the activities in one of its four working groups, dealing with evolutionary change and prediction of invasion. In addition, together with former MSc student Alvaro Luna and collaborators across Europe, we have investigated to what extent the timing of reproduction in the Ring-necked parakeet may prevent establishment or reduce population growth in certain parts of Europe. In the north, eggs appear to be laid too early in the year when food may be limiting for young chicks early in spring. We are also reanalysing what current snapshots of population genetic structure and composition can tell us about past founding population sizes versus continued influx of additional (released or escaped) birds. We are also working on a paper on the social perception of the parakeet in Seville and other cities in Europe, and on conceptual and practical papers aiming to clarify and improve the assessment of invasion by biological invaders.
