Incongruence between morphological and molecular data.
Ongoing Research Projects:
important result of this work regards the invasive
species P. griseola. Previously it
was believed that there was a single invasive
Praticolella species, my work found
there are actually three species of
Praticolella invasive in the
Phyloclimatics is a new area of evolutionary biology that brings together spatial analyses and systematics. My postdoctoral research builds on my previous work on the systematic relationships in Praticolella to examine phylogenetic niche conservatism. I am using the phylogenetic relationships of snails to examine the evolution of morphology and environmental niche in replicate pairs of sister-taxa. Contrary to the expectation of niche conservatism, results so far indicate that in these snails sister-taxa have non-overlapping geographical and niche envelopes as well as distinct morphologies.
I am also building on the framework provided by my previous research and expanding this work into the entire family Polygyridae, an important North American group of land snails.
