Welcome! Visit the UPRM-INVCOL Blog.

Welcome to the Insect Systematics & Evolution laboratory of the University of Puerto Rico at Mayagüez (UPRM). Our lab started at UPRM in 2006. Current research activities include a range of practical and conceptual themes, with a primary focus on the systematics, evolution, and natural history of weevils (Coleoptera: Curculionoidea) in the Caribbean and greater Neotropical region. Additional interests include the systematics and natural history of Puerto Rican beetles, in particular herbivorous taxa such as the Phytophaga and their host plant associations. Although many islands are only moderate in local biodiversity, the Caribbean region in its entirety still holds many interesting discoveries in the insect world, and to a degree these hidden treasures affect our evolving research program.

One major and ongoing project focuses on the systematics, molecular evolution, and historical biogeography of broad-nosed weevils (Entiminae) in the Caribbean and Neotropical region (DEB-0641231). Recently our lab has expanded its taxonomic emphasis to include Neotropical staphylinids, hoverflies, and cockroaches, among other insect lineages.

This webpage contains information on lab members, courses offered, a call for prospective students, and links to PDFs of our publications including CURCULIO - an international newsletter for weevil research. For further inquiries please contact us directly.

 

UPRM Invertebrate Collection

UPRM's campus houses the second largest invertebrate collection on the island (click here for the larger MEBT-MC collection), with approximately 135,000 specimens. The collection was initiated by the renown ornithologist and natural historian Stuart Danforth in the 1920s. Subsequent major contributors include José Ramos and Jenaro Maldonado Capriles (Hemiptera), Stuart Ramos (Lepidoptera), and José Mari Mutt (Collembola). After several years of relative inactivity, the collection is now being inventoried and improved in numerous regards. In March 2008 we received an award from the National Science Foundation - Biogical Research Collections program (DBI-0749434) to significantly upgrade the collection infrastructure.
