Introduction
I currently am a postdoc in the Department of Wildlife and Fisheries Sciences, Texas A&M University. My research interests include systematics, evolutionary biology, and host-parasite coevolution particularly of diurnal birds of prey and their associated ectoparasites.

Article
Full-text available
South Texas is a highly variable region encompassing multiple habitat types and harboring a wide diversity of organisms. However, the parasite fauna in this region is poorly known, especially for avian ectoparasites such as lice. To better understand avian louse diversity and host associations in South Texas, we examined a total of 507 birds for ch...
Article
More than one-third of the bird species found in the Caribbean are endemic to a set of neighboring islands or a single island. However, we have little knowledge of the evolutionary history of the Caribbean avifauna, and the lack of phylogenetic studies limits our understanding of the extent of endemism in the region. The Sharp-shinned Hawk (Accipit...

Megascops is the most species-rich owl genus in the New World, with 21 species currently recognized. Phylogenetic relationships within this genus are notoriously difficult to establish due to the considerable plumage similarity among species and polymorphism within species. Previous studies have suggested that the widespread lowland Amazonian M. wa...
Article
Unlike most bird species, individual kingfisher species (Aves: Alcedinidae) are typically parasitized by only a single genus of louse ( Alcedoffula , Alcedoecus , or Emersoniella ). These louse genera are typically specific to a particular kingfisher subfamily. Specifically, Alcedoecus and Emersoniella parasitize Halcyoninae, whereas Alcedoffula pa...

Aligning sequences for phylogenetic analysis (multiple sequence alignment; MSA) is an important, but increasingly computationally expensive step with the recent surge in DNA sequence data. Much of this sequence data is publicly available, but can be extremely fragmentary (i.e., a combination of full genomes and genomic fragments), which can compoun...
Article
Full-text available
The diversity of permanent ectoparasites is likely underestimated due to the difficulty of collecting samples. Lice (Insecta: Phthiraptera) are permanent ectoparasites of birds and mammals; there are approximately 5,000 species described and many more undescribed, particularly in the Neotropics. We document the louse genera collected from birds sam...

Full-text available
The phylogenetic status and relationships of the globally distributed grassland leafhopper tribe Hecalini were explored by analyzing a DNA sequence dataset comprising three gene regions (nuclear 28S rDNA, histone H3, 12S mtDNA) for 14 genera and 29 species plus 9 outgroups. Bayesian, maximum likelihood, and maximum parsimony analyses recovered simi...
Article
Full-text available
Managers are a strength of policy implementation in the changing and complex landscape of natural resources management. We argue future managers will require additional educational emphases such as coursework in evolution to confront emerging issues in this dynamic profession. An emphasis on more management-oriented evolution education at the colle...
Article
Full-text available
The chewing louse genus Colpocephalum parasitizes nearly a dozen distantly related orders of birds. Such a broad host distribution is relatively unusual in lice. However, the monophyly of the genus Colpocephalum has never been tested using molecular characters. Using one nuclear and one mitochondrial gene, we inferred a phylogeny for 54 lice from t...
Article
Although diurnal birds of prey have historically been placed in a single order due to a number of morphological characters, recent molecular phylogenies have suggested that this is a case of convergence rather than homology, with hawks (Accipitridae) and falcons (Falconidae) forming two distantly related groups within birds. The feather lice of bir...
Article
The use of intuitive or explicit biogeographical reconstruction techniques to estimate the timing of species radiations on the Hawaiian Islands, while often incorporating evidence on the timing of island formation, may be misleading if the effects of extinction are overlooked. Using phylogenies of the bark louse genus Ptycta (Psocidae), we compared...
Article
A phylogenetic analysis of Xyphon was completed using 45 adult morphological characters and 1,076 base pairs of the mtDNA gene NADH dehydrogenase 1. Multiple specimens, representative of the range of morphological variation found in each previously described species, were scored for the morphological data matrix to test the monophyly of each specie...

Conference Paper
Patterns of grassland biogeography were inferred using 3 tribes of leafhoppers (Deltocephalini, Paralimnini, and Hecalini) and a family of planthoppers (Caliscelidae). Previous biogeographic study of this biome has been based on ungulates or other groups which have either limited distributions, or a small number of taxa. Although little is known ab...
Conference Paper
Paralimnini Distant 1908 is distributed worldwide and currently contains 127 genera and about 500 species. Most members of the tribe are closely associated with grass dominated habitats including North America prairies, pampas in South America, the steppes of central Asia, and African savannahs. Based on both morphological and molecular data Parali...
Article
Based on museum-held and field-collected specimens new data are presented regarding the distribution, adult phenology and first-instar larva of the uncommon green lacewing Abachrysa eureka. It was found that this species is broadly distributed across the southeastern United States, from Texas to the east coast south to Florida and north to South Ca...

Leafhoppers (Hemiptera:Cicadellidae) are common plant-feeding insects. The leafhopper fauna of Dominica, West Indies, has not been surveyed. This paper is a starting point at describing Dominica's leafhopper community. Leafhoppers were collected daily from 23 May 2006 to 12 June 2006 using a variety of techniques and then sorted into morphogroups....

Fulgoroid planthoppers (Hemiptera: Fulgoroidea) are common plant-feeding insects. Although the planthopper fauna of Dominica, West Indies, has been studied and is fairly well-known, this study was conducted in hopes of building on the previous work. Planthoppers were collected daily from 23 May 2006 to 12 June 2006 using a variety of techniques and...
