Research

We utilize a combination of fieldwork, ecological data, genomics, and bioinformatics to study how organisms evolve across both geographic and genomic landscapes.


Avian Population Genomics

We are studying the diversification of birds at the population, landscape, and continental levels using whole-genome sequencing methods.

Current Projects:

  1. Population genomics and phylogeography in several avian taxa
  2. Landscape genomics of nuthatches
  3. Biodiversity genomics through time of Eastern African montane birds (currently NSF funded)

Relevant Products:

Ant-Microbe Co-Evolution

We are studying the codiversification of Camponotus carpenter ants and their Blochmannia endosymbionts using whole genome sequencing methods and ecological data. We are currently focusing on North American taxa.

Current Projects:

  1. Effects of host demography on endosymbiont genome evolution
  2. Landscape genomics of several North American Camponotus species
  3. Microbial community ecology in Camponotus hosts

Relevant Products:

  • Manthey JD, Girón JC & Hruska JP. (Preprint) Impact of host evolutionary history on endosymbiont genome evolution: a test in Camponotus carpenter ants and their Blochmannia endosymbionts. DOI: 10.22541/au.160689628.80980759/v1

Genome Evolution

We are using multiple sequencing types, including whole-genome and transcriptome data, to understand how structural variants and more specifically transposable elements (TEs) are evolving in genomes, as well as how these changes impact diversification in multiple organisms.

Current Projects:

  1. Effects of TEs on molecular evolution in woodpeckers
  2. Population genomics of TEs in multiple avian groups
  3. Landscape genomics of TEs in carpenter ants

Relevant Products:
