Former Ph.D. student Leyla Davis (University of Zurich) publishes her research in Environmental Microbiology

Former Ph.D. student Leyla Davis (University of Zurich) and Doug Woodhams collect samples for project reported in Environmental Microbiology

We found that the response of tadpoles to microbial therapy depended on the initial microbial community structure.  Addition of Flavobacterium and Pseudomonas acted to increase survival of infected tadpoles.

Brandon LaBumbard honored for Outstanding Teaching.

Brandon LaBumbard received a Department of Biology Award for Outstanding Teaching. In addition to courses in Introductory Biology, and a January term Research Immersion course, Brandon is always teaching students in the lab.

Jonah Piovia-Scott and colleagues publish on bacteria diversity-function relationship in Microbial Ecology

Experimental biofilms with diverse bacterial communities.

Diversity-function relationships are a frontier of ecology research.  Here, we look at the function of bacterial communities to suppress chytrid fungus, and they do this better when at higher diversity.

Fighting the fungal diseases that have killed millions of frogs and other amphibians is a top priority, and new research suggests natural soil bacteria might provide protection. UMass Boston biology professor Doug Woodhams tells Living on Earth’s Helen Palmer how they work, and might help other species threatened by these illnesses.

Trends in Microbiology publishes new study: Managing Amphibian Disease with Skin Microbiota

In a section on Science and Society, Woodhams and colleagues describe state-of-the-art approaches for amphibian disease management.  These include probiotic bacteria that persist from aquatic tadpole to terrestrial adult frog stages, and bacteria that produce volatile compounds including hydrogen cyanide that can kill fungus from a distance and could be applied to soils. These management tools were announced on the heels of a moratorium on salamander trade to help prevent invasion by a new salamander chytrid.  This is the 50th peer-reviewed publication from new assistant professor Doug Woodhams, and was supported by the UMass Boston Endowed Faculty Career Development Award.

Amanda Peters, new IGERT fellow at the Woodhams lab.

Amanda Peters was selected as a Coasts and Communities IGERT fellow and joins the Woodhams lab in August 2016.  Amanda is graduating from Washington College in Maryland with a double major in Biology and Environmental Science. She will be involved on the project entitled, “Linking Microbiota and Ecotoxicology with Mosquito-Borne Disease Risk” supported by a seed grant from the Office of Research, Strategic Initiatives and Graduate Studies.

In this new article in EcoHealth, Dr. Woodhams with collaborators at University of Colorado Boulder suggests that antimicrobial peptide defenses do not play a significant role in defending larval amphibians against trematode cercariae, but that they could be one mechanism helping to prevent infection of post-metamorphic amphibians, particularly for highly aquatic species.
