Accounting for interspecific competition and age structure in demographic analyses of density dependence improves predictions of fluctuations in population size.

abstract：:Latitudinal gradients in biotic interactions have been suggested as causes of global patterns of biodiversity and phenotypic variation. Plant biologists have long speculated that outcrossing mating systems are more common at low than high latitudes owing to a greater predictability of plant-pollinator interactions in ...
