Michael J Adams

I lead the USGS Amphibian Research and Monitoring Initiative (ARMI) and the Herpetological Research Team at the Forest and Rangeland Science Center in Corvallis, Oregon

Research in my lab focuses on amphibian conservation issues. We are currently addressing issues such as invasive species, disease, land use change, and long-term monitoring design for amphibians in North America. We use a combination of comparative surveys and manipulative experiments to understand the factors affecting amphibian distribution and abundance.

Herpetological research at the USGS FRESC

Herpetological Research Team (FRESC)

The Herpetological Research Team focuses on issues related to conservation and management of amphibians and other aquatic and semi-aquatic species. Among our current studies are effects of invasive species, disease, and land use change on the dynamics of amphibian communities to inform conservation and management decision making.

A Protocol for Aging Anurans Using Skeletochronology A Protocol for Aging Anurans Using Skeletochronology

Age distribution information can be an important part of understanding the biology of any population. Age estimates collected from the annual growth rings found in tooth and bone cross sections, often referred to as Lines of Arrested Growth (LAGs), have been used in the study of various animals. In this manual, we describe in detail all necessary steps required to obtain estimates of age...

Analytical Results for Municipal Biosolids Samples from a Monitoring Program Near Deer Trail, Colorado (USA), 1999 through 2006 Analytical Results for Municipal Biosolids Samples from a Monitoring Program Near Deer Trail, Colorado (USA), 1999 through 2006

Since late 1993, Metro Wastewater Reclamation District of Denver (Metro District), a large wastewater treatment plant in Denver, Colorado, has applied Grade I, Class B biosolids to about 52,000 acres of non-irrigated farmland and rangeland near Deer Trail, Colorado. In cooperation with the Metro District in 1993, the U.S. Geological Survey (USGS) began monitoring ground water at part of...

Range-wide phylogeographic analysis of the spotted frog complex (Rana luteiventris and Rana pretiosa) in northwestern North America Range-wide phylogeographic analysis of the spotted frog complex (Rana luteiventris and Rana pretiosa) in northwestern North America

The dynamic geological and climatic history of northwestern North America has made it a focal region for phylogeography. We conducted a range-wide phylogeographic analysis of the spotted frog complex (Rana luteiventris and Rana pretiosa) across its range in northwestern North America to understand its evolutionary history and the distribution of clades to inform conservation of R...

Demography and movement in a relocated population of Oregon Spotted Frogs (Rana pretiosa): Influence of season and gender Demography and movement in a relocated population of Oregon Spotted Frogs (Rana pretiosa): Influence of season and gender

We used five years of recapture data and Bayesian estimation to assess seasonal survival, movement, and growth of Oregon Spotted Frogs (Rana pretiosa) relocated into created ponds at Dilman Meadow in Oregon, USA. We evaluate hypotheses specific to the relocation and elucidate aspects of R. pretiosa life history that are poorly known. The odds of survival of relocated individuals during...
