Effets des pratiques agricoles et des infrastructures agro-écologiques sur la diversité des Chiroptères

Abstract : Agricultural intensification and landscape oversimplification would be the two major causes of european population bats declines. This study aim to find what variable of agricultural practices and landscape elements (AEI) influence strongly the diversity of bats on meadows. The taxonomic and functional diversity has been established with records sampled between June and July 2013. The plots of land were define along a gradient of land-use intensity and landscape structure and were chosen among 35 farmlands, designated in three different regions. A seasonal variation of plot visiting by bats were reported in comparison with the records taped in August/September 2012, due to a peak of activity during this stage. The bat activity measures (number of bat calls per hour) allow to classify the factors which have an effect on bat visiting. The activity of bat specialists could that way be fixed by the grass use of pasture land, one of the variables which has a significant impact on bat diversity. The frequence of mowing and the fertilization are also powerful elements for diversity. The AEI presence, in particular pond, hedgerow, scattered trees and forest density, seems to promote bat diversity.
