Life history strategies affect climate based spatial synchrony in population dynamics of West African freshwater fishes
Article Abstract:
The degree of synchrony induced by a Moran effect among several tropical freshwater fish species belonging to the periodic and equilibrium strategies are compared from two different drainage basins of Ivory Coast. The degree of inter-specific synchrony of periodic species is high as the reproduction depends on hydrology, whereas for equilibrium species, local habitat conditions favorable for reproduction can vary between sites and species, presumably resulting in lower inter-specific synchrony.

Spatial synchrony in population fluctuations: Extending the Moran theorem to cope with spatially heterogeneous dynamics
Article Abstract:
The population dynamics is described by linear and stationary autoregressive progress to show that the observed spatial synchrony between two populations can be decomposed into two multiplicative components. The Moran theorem has corresponded to the special case where the demographic component equals unity, also showing that the spatial variability in population dynamics might substantially contribute to the spatial variability of population synchrony.

Synchrony in brown trout, Salmo trutta, population dynamics: a 'Moran effect' on early-life stages
Article Abstract:
The study analyses the spatio-temporal patterns of fluctuation of 57 brown trout populations across France, over a period of five years. The influence of dispersal and auto-correlated climatic factors (the 'Moran effect') is discussed.
