The National Science Foundation has granted Professor Woodhams the prestigious Faculty Early Career Development Award.  The award will fund five years of research in the Woodhams Lab, focusing on Microbiome Regulation by Amphibian Skin Peptides, and will support a new course, Microbiome and Disease Ecology Lab, focused on authentic research experiences for undergraduates. Congratulations Dr. Woodhams!

Nature Ecology and Evolution publishes a new collaborative study with UMass Boston researchers

Nature Ecology and Evolution published a new collaborative study with UMass Boston researchers Jordan Kueneman, Molly Bletz, Rob Stevenson, and Doug Woodhams.  The study found that bioclimatic factors were important in shaping the skin microbiome of amphibians at a global scale. Samples from over 2,300 amphibians of 205 species were included in the study.

Science Magazine publishes Woodhams Lab findings

Science Magazine publishes a sweeping study including 15 years of Dr. Woodhams’ research. In collaboration with Jamie Voyles at University of Nevada, Reno, the study describes rebounding populations of amphibians in Panama. Rather than a weakening pathogen, the research shows that host skin defenses or biotic community factors may be responsible for creating conditions for coexistence of amphibians and the chytrid fungus.

New article, Fight Fungi with Fungi: Antifungal Properties of the Amphibian Mycobiome, published in Frontiers in Microbiology

Network analysis depicting the connectivity among sample for Bd inhibitory bacterial (A) and Bd-inhibitory/facilitating fungal (B) taxa.

In this new article published in Frontiers in Microbiology, the Woodhams Lab in collaboration with the New England Aquarium suggests that host associated fungi may work better than bacteria for amphibian skin probiotics against chytridiomycosis.

NIH-Bridges to Baccalaureate student George Khnaizir presents summer research

George Khnaizir presents his summer research, conducted at the Woodhams Lab under the mentorship of Dr. Andreas Hertz, at this year’s Annual Biomedical Research Conference for Minority Students in Pheonix, AZ.  The title of his research is Amphibian Mucosal Defenses Against an Emerging Fungal Disease: Testing for selection in recovering populations in upland Panama.

NPR’s Living On Earth interviews Dr. Woodhams: Good Bacteria Could Save Amphibians

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

Trends in MicroBiology 1

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.

EcoHealth publishes new study: Antimicrobial peptide activity against trematode parasites

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.
