After decades of debate, biologists today largely agree that most speciation events require
an allopatric phase (that is, geographic separation), but the role of adaptive ecological …

Plants are widely recognized as chemical factories, with each species producing dozens to
hundreds of unique secondary metabolites. These compounds shape the interactions …

Coexisting (sympatric) pairs of closely related species are often characterized by
exaggerated trait differences. This widespread pattern is consistent with adaptation for …

Determining the link between genomic and phenotypic change is a fundamental goal in
evolutionary biology. Insights into this link can be gained by using a phylogenetic approach …

Premise A switch in pollinator can occur when a plant lineage enters a new habitat where
the ancestral pollinator is less common, and a novel pollinator is more common. Because …

Aim The remarkable ecomorphological diversity of the bat superfamily Noctilionoidea is the
result of a diet‐mediated adaptive radiation. Stemming from a putatively insectivorous …

Plants carry genetic material in three separate compartments, the nuclear, mitochondrial,
and chloroplast genomes. These genomes interact with each other to various degrees and …

In this thesis I attempt to better understand the general role played by adaptive ecological
divergence in the evolution of new species. For the past two decades, evolutionary …
