Genetic analysis of Ximenia Americana under natural conditions
Cross-species hybridization approaches have been used for genetic analysis of species that do not have complete genome arrays available. The study used the cross-species DNA-DNA hybridization approach to characterize Ximenia americana biological processes. Preliminary micro-array studies done in …

Nuclear and cytoplasmic genetic variation in Picea: DNA markers for evaluating past migration, introgression and evolutionary history
… three monophyletic groups that were nearly 100% species-specific. These results strongly refute a previously proposed progenitor/derivative relationship of black/red spruce. Red and black spruce were estimated to have diverged from their common ancestor ∼0.6--3.5 million years ago. …

Assessing the Phylogenetic and Cultural Content of Learned Song
… learned by a juvenile from a tutor of the same species, in a pattern that is analogous to human language, and likewise has the potential to change over time by cultural evolution. The similarities between human languages have been studied for centuries, but historically the relationships between …

Population Genomics, Ecology and Conservation of <i>Asterias</i> Sea Stars in the North Atlantic
<p>Uncovering how species respond to environmental change is a central question in biology (Ehrlén & Morris 2015; Habibullah <em>et al.</em> 2022). It is the key to elucidating the past, understanding the present and predicting the future of species’ population dynamics. This dissertation …

Role of Hybridization in a Biological Invasion: An Experimental Study with Silene Latifolia
… leading cause of loss of biodiversity. Recently, hybridization has been hypothesized as a mechanism for invasion success. The combination of individuals from different gene pools may create novel genotypes having increased invisibility. The goal of my research was to examine the role that …
