update

An updated write-up about my experiences with Crenicichla celidochilus can be found here.

However, it will be updated further in the near future!

Current Research (Updated February 2014)

My research deals with ecological diversification among Neotropical cichlids (Teleostei: Cichlidae: Cichlinae), with particular emphasis on Crenicichla (Cichlidae) in subtropical South America. I am interested in the evolution of body shape and lower pharyngeal jaw shape among major lineages, particularly, shifts in rates of evolution and convergence. To address these interests, I using next generation sequencing, geometric morphometrics, stable isotope ratios and organismal stoichiometry.

Secondly, I am interested in the comparative functional ecology of four freshwater crustacean lineages in subtropical South America: Paractacidae ("crayfish"), Trichodactylidae ("crabs"), Palaemonidae ("shrimps"), and Aeglidae. I am particularly interested in how the apparent intermediate morphology of Aeglidae (between crayfishes/shrimps and crabs) manifests itself from a functional perspective.

Lastly, I am interested in the functional roles and trophic relationships among sympatric minnows in the Southeastern US (Cyprinidae). Particularly, morphological-ecological associations and linkages between species identity and ecosystem function.

Crenicichla celidochilus pair with fry

It's been a big week in the fish room. I've been trying to breed these for about a year and a half.

It's summertime again, which for me means working with golden-winged and blue winged warblers. All these photos are from Roan Mountain, TN.
