Ecological Factors and Diversification among Neotropical Characiforms

International Journal of Ecology, Volume 2012, Issue 1, 2012., 2012
Morphological and DNA sequence data has been used to propose hypotheses of relationships within the Characiformes with minimal comparative discussion of causes underpinning the major intraordinal diversification patterns. We explore potential primary morphological factors controlling the early diversification process in some Neotropical characiforms as
