Quail (Coturnix coturnix) Science Article 6
abstract
The existence of interannual variations in the richness and abundance of bird species breeding in pseudo-steppic Mediterranean areas is analysed and related to the important fluctuations that take place in rainfall, which in turn deeply influence vegetation growth. The hypothesis of food limitation as a key factor in determining population sizes, allows the prediction of the existence of positive correlations between these parameters.
