Weather variation affects the dispersal of grasshoppers beyond their elevational ranges

Understanding how abiotic conditions influence dispersal patterns of
organisms is important for understanding the degree to which species can
track and persist in the face of changing climate. The goal of
this study was to understand how weather conditions (temperature,
precipitation and wind patterns) influence the dispersal
patterns of multiple non-migratory grasshopper species from lower
elevation grassland habitats in which they ­­complete their life-cycles to
higher elevations that extend beyond their range limits. The study also
explored the role of weather factors (temperature and precipitation) in
influencing the population sizes of species found at lower
elevations.
