| Results indicated that juveniles and adults did not show exogenous regulation, while recruitment was negatively related to winter rainfall and positively to spring rainfall. A clear cohort effect was detected affecting the density of juvenile age class. However, effect of the density of juveniles during the previous year on the density of adults at a given year was not detected. Adults were only positively related to adult abundance in the previous year. Winter rainfall was the main environmental factor causing synchrony on recruitment through a Moran effect. The greater the difference among their altitude, distance to upper limit (DUL), Fluvial Habitat Index (IHF) and geographical position, the lower the similarity of response to winter rainfall, and consequently the lower the Moran effect. Once identified, this asynchronizing habitat features should be preserved (or restored) in order to guarantee the lack of demographic synchrony among demes within a given metapopulation, since according to Heino et al. (1997), it is asynchrony, not chaos, what reduces the probability of global extinctions. | |
