Abstract

Studies addressing the influence of climatic and ecological factors in speciation has become more common in recent years. One of the issues explored is the niche conservatism (CN), which is the tendency of species and clades may have in maintaining ecological characteristics over time. The CN can help clarify questions about speciation, and thus our study will be directed to investigate whether CN can explain the allopatric speciation. As a group model for the study will use the Clade criuva (Clusia, Clusiaceae), composed of six sections. The Clade criuva has a strong variation in floral morphology, which may have been driven by different pollinators that could have occupied distinct climatic niches. For our study, first we will carry out a taxonomic revision of the Clade criuva and assemble a database of species occurrence and characteristics of the local climate. From ITS sequences (plus others to be identified), rebuild the phylogeny of Clade criuva. When the phylogenetic analysis and database are complete, we will make ecological niche modeling and examine patterns of niche conservatism or divergence in the light of the phylogeny of Clade criuva and complementaremos discussions with data from reproductive biology. Our study is part of a line of modern research and still under construction, and thus our work can directly contribute to the solidification of the theory of niche conservatism. As final products, we intend to publish a taxonomic revision for Clade Criuva, a phylogenetic analysis for the clade and a research niche conservatism, and articles with descriptions of new species.
