MOLECULAR TRANS-SPECIES POLYMORPHISMAnnual Reviews - Tập 29 Số 1 - Trang 1-21 - 1998

▪ Abstract Trans-species polymorphism (TSP) is the occurrence of similar alleles in related species. Excluding instances in which the similarity arose by convergent evolution, TSP is generated by the passage of alleles from ancestral to descendant species. Closely related, recently diverged species, such as those of the Lake Victoria cichlid flock, may share neutral alleles, but long-last...... hiện toàn bộ
The Ecology of Interfaces: Riparian ZonesAnnual Reviews - Tập 28 Số 1 - Trang 621-658 - 1997
Robert J. Naiman, Henri Décamps
Riparian zones possess an unusually diverse array of species and environmental processes. The ecological diversity is related to variable flood regimes, geographically unique channel processes, altitudinal climate shifts, and upland influences on the fluvial corridor. The resulting dynamic environment supports a variety of life-history strategies, biogeochemical cycles and rates, and orga...... hiện toàn bộ
