Dr. Armbruster is  particularly interested in reconstructing the evolution of the genera of the South American suckermouth armored catfishes or plecos (Loricariidae) using morphological characteristics. I also explore in detail various types of morphological systems such as those related to wood-eating in some loricariid catfishes and accessory respiratory structures. Wood-eating is found in two genera of loricariid catfishes and is accompanied by changes in the bones and the evolution of large spoon-shaped teeth. Many loricariids breathe air and there is a large number of adaptations the fishes use to do so including what appears to be a unique evolution of a lung and a unique evolution of a swim-bladder from that lung. I am also involved in taxonomic revisions of many groups of loricariids as well as other fishes . In addition, I am active in exploring the biodiversity of the planet, particularly that of South America. Studies are underway in Venezuela and Guyana (photo above is taken at Kaiteur Falls in Guyana) to determine what fish species are there and what impact humans may be having on them.

Dr. Chavez studies Pterygoplichthys species that was introduced in the Philippines as an ornamental fish. Because of its perceived ability to clean dirty water of its algae content, this fish was released in a number of waterways in the Philippines and has been proliferating in the second largest lake in Asia--the Laguna de Bay. Its introduction already has caused economic damage to many fisher folks but its ecological impact is yet to be elucidated. For now, we do know there are two species of the fish living in almost the same waterways leading to Laguna de Bay whereas they live in separate regions in the their original range in South America.

Dr. German is an ecophysiologist interested in digestive mechanisms, microbial processes, and more recently, global change.  Much of my work during my graduate career was focused on the digestive physiology of fishes.

Dr. Lujan is most interested in the interplay between intrinsic and extrinsic diversification mechanisms of primary consumers in tropical rivers and streams. My research to date has focused on the Neotropical suckermouth armored catfishes (Loricariidae), for which I have employed an interdisciplinary approach combining relatively traditional methods of describing jaw functional morphology with modern and/or novel methods of describing community trophic structure and historical biogeography.

These researchers are currently or have recently finished working with loricariids.  If research information was provided, it was typically removed from the website of the person in question.

If you are currently conducting research on native or invasive populations of loricariids, and would like to add your information to the webpage please fill out the following form:

 

The goal of this section of the PlecoInvasion is to create a center of information for expertise and on-going investigations of loricariids. We are interested in gathering information from people working with both native and invasive populations of armored catfish in order to understand as much as we can about these fishes. Names of researchers appear in alphabetical order.
