Investigation of dispersal ecology and evolution using laboratory populations of Drosophila melanogaster

A MISHRA - 2020 - dr.iiserpune.ac.in

range expansions. The process underlying these phenomena (ie dispersal), however, is …

Selection for greater dispersal in early life leads to increased rate of age-dependent decline in locomotor activity and shorter lifespan

BG Ruchitha, N Kumar, C Sura, S Tung - bioRxiv, 2022 - biorxiv.org
Locomotor activity is one of the major traits that is affected by age. Greater locomotor activity
is also known to evolve in the course of dispersal evolution. However, the manner in which …

Dispersal evolution diminishes the negative density dependence in dispersal

A Mishra, PP Chakraborty, S Dey - Evolution, 2020 - academic.oup.com
In many organisms, dispersal varies with the local population density. Such patterns of
density-dependent dispersal (DDD) are expected to shape the dynamics, spatial spread …
