Pagamea Aubl. (Rubiaceae), From Species To Processes, Building The Bridge, Alberto Vicentini Jul 2007

Pagamea Aubl. (Rubiaceae), From Species To Processes, Building The Bridge, Alberto Vicentini

Dissertations

Species delimitation have a great impact in scientific, environmental and other human activities, and is fundamental for understanding evolution. Plant species are usually delimited based on morphology and rarely species concepts are stated and analysis of variation made explicit. Botanists do see species as ?segments of evolutionary lineages?, but reproductive isolation is rarely addressed. Yet, reproductive isolation is necessary for understanding species, because speciation is the process of acquiring reproductive barriers. Almost any lineage will have species at different stages of isolation, and a single type of data will be insufficient for species delimitation. In plants, other biological processes such …
