Partial migration: niche shift versus sexual maturation in fishes
Many fish populations have both resident and migratory individuals. Migrants usually grow
larger and have higher reproductive potential but lower survival than resident conspecifics …

Evolutionary significance of resource polymorphisms in fishes, amphibians, and birds
▪ Abstract Resource polymorphism in vertebrates is generally underappreciated as a
diversifying force and is probably more common than is currently recognized. Research …

The evolution of threshold traits in animals
DA Roff - The Quarterly Review of Biology, 1996 - journals.uchicago.edu
Within a population there are frequently several discrete morphs. While in some cases,
particularly color polymorphisms, this variation can be explained by simple Mendelian …
