Population structure of the lizard Ecpleopus gaudichaudii coincides with a biogeographic barrier - the Doce River
… Atlantic Forest of Brazil. For that, I assembled ddRadseq sequences from 48 individuals across much of the range of the <em>E. gaudichaudii </em>and analyzed its population structure. I created an intraspecific phylogeny for this group utilizing RAxML and conducted a principal component analysis …

Taxonomic Revision of the Pirate Perches (Percopsiformes: Aphredoderidae) Reveals Three New Species and Elevates Two Subspecies
… Atlantic drainages. I use morphology and ddRADseq from specimens spanning the entire range of the genus to determine species limits within Aphredoderus. I find evidence of five species, four of which exhibit widespread sympatry in the Southeastern United States. I elevate A. sayanus …

The Evolutionary Causes and Consequences of Mammalian Hybridization
… I generated mitochondrial haplotypes and ddRADSeq data from tissues from museum collections to show that (1) there are two main genetic linages of cottontails in Colorado (eastern and desert cottontails), (2) that both species are hybridizing in urban areas, and (3) that these species are …

A multidisciplinary approach to informing conservation decisions for the threatened frog Mantella cowanii
… during 2015–2024. Genomic analyses using ddRADseq data revealed low to no inbreeding, limited population structure among sites, and evidence of hybridization with the closely related M. baroni. The hybrid populations clustered more closely with M. baroni than M. cowanii, and admixture was …

Cryptobenthic Coral Reef Fishes: Resolving Critical Gaps in Species Delimitation, Sampling Techniques, and Phylogenetic relationships
… digest restriction site associated sequencing (ddRADseq), in combination with morphological data to infer the number of species in the E. sigillata complex. Specifically, I constructed phylogenetic trees and conducted several types of single-locus and multilocus species delimitation analyses and …

A Genomics Approach to Conservation, Systematics, and Phylogeography to Understand Two Lineages of Lamiales
… Using a next-generation sequencing approach (ddRADseq), this study (1) estimates a wellsampled phylogeny of the tribe, (2) tests genera and sub-generic groups for monophyly, (3) identifies morphological characters that support monophyletic groups, (4) examines patterns of biogeography and …

Old World Serpents and New World Dragons: The Evolutionary Dynamics of Pythons and Liolaemid Lizards
… Single Nucleotide Polymorphisms (SNPs) using ddRADSeq, and used cutting edge phylogenetic reconstruction methods to resolve the evolutionary history of the group. I find very high levels of discordance between mitochondrial and nuclear data, suggesting extensive past introgression between …
