Phylogenetic Evidence for the Gain and Loss of a Sexually Selected Trait in Sailfin Mollies [PDF]

International Scholarly Research Notices, Volume 2011, Issue 1, 2011., 2011
A phylogenetic comparative approach was used to examine the evolution of the enlarged “sailfin,” characteristic of the monophyletic lineage of sailfin mollies (Poecilia: Mollienesia), but absent in one of its species, P. latipunctata. Ancestral character state reconstructions demonstrated that the ancestral sailfin molly possessed the enlarged sailfin,

Contrasting genetic structure in two codistributed freshwater fish species of highly seasonal systems Estructura genética contrastante en dos especies codistribuidas de peces de agua dulce que habitan sistemas marcadamente estacionales

Revista Mexicana de Biodiversidad, 2009
Given the seasonal nature of ecosystems such as permanent sinkholes ('cenotes') and temporary wetlands, their fish fauna experience yearly local extinction and colonization processes, with strong fluctuations in population size.
