Most organisms live in a seasonal environment. During their life cycles, some species face seasons of cold and heat, aridity abundant rainfall, migration stable residence, breeding nonbreeding. Populations grow decline as supplies materials essential to survival wax wane. Such qualitative truths these flow obviously from field observations. In this original monograph, Stephen Fretwell analyzes the highly complex interaction between population regularly varying environment an attempt define...
Breeding bird censuses were made in Puerto Rico, Panama, and temperate United States, a profile of foliage density was for each. Using information theory formulae both diversity indices measurements difference between habitats can be made. Based on these, the following verified directly from data: 1. Rico has nearly as many species per layer Panama regions, but Rican appear to recognize fewer layers certainly subdivide much less. Thus different are likely have quite similar unlike States.
1 Dramatic reductions in dispersal potential are characteristic of many diverse taxa, both plants and animals, on oceanic islands. This paper documents the same trend reduced ability over course just a few generations some weedy, short-lived wind-dispersed inshore islands British Columbia, Canada. 2 We measured dispersal-related morphological characteristics diaspores from island populations known ages, mainland populations. In two three species with sufficiently large sample sizes, older...

Ecological isolating mechanisms based on differences in size or breeding season operate many groups of related sympatric seabirds, but not the alcid species (Aves: Fam. Alcidae) found together Washington State. At least three six coexisting have similar diets, and all breed at same time year. They differ, however, their foraging zones sea appear to reduced interspecific competition by this means. Diverse aspects biology, behavior morphology ecology these alcids can be explained reference two...
