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.
Professional Experience
1997 - Present: USGS, Forest and Rangeland Ecosystem Science Center, Supervisory Research Ecologist, Corvallis, OR
Education and Certifications
Ph.D., Wildlife Science, University of Washington, Seattle, WA (1997)

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.

Chemical analyses of ground and surface waters, Ester Dome, central Alaska, 2000-2001 Chemical analyses of ground and surface waters, Ester Dome, central Alaska, 2000-2001
Water analyses are reported for ground and surface waters collected at 33 sites on and near Ester Dome, Fairbanks area, central Alaska during 2000-2001. This interdisciplinary study focused on documenting the temporal and spatial chemical variations in arsenic concentrations to elucidate the processes that lead to elevated arsenic concentrations in ground water. Field parameters and...

Optical characteristics of natural waters protect amphibians from UV-B in the U.S. Pacific Northwest Optical characteristics of natural waters protect amphibians from UV-B in the U.S. Pacific Northwest
Increased exposure to ultraviolet-B (UV-B) radiation has been proposed as a major environmental stressor leading to global amphibian declines. Prior experimental evidence from the U.S. Pacific Northwest (PNW) indicating the acute embryonic sensitivity of at least four amphibian species to UV-B has been central to the literature about amphibian decline. However, these results have not...

The endemic headwater stream amphibians of the American Northwest: Associations with environmental gradients in a large forested preserve The endemic headwater stream amphibians of the American Northwest: Associations with environmental gradients in a large forested preserve
We used a large forested preserve (Olympic National Park, USA) to examine the habitat associations of a unique and environmentally sensitive stream amphibian fauna: Ascaphus truei Stegneger, Rhyacotriton olympicus (Gaige) and Dicamptodon copei Nussbaum. We quantified the relative abundance of stream amphibians and compared them to physical, topographic, climatic and landscape variables...

Association of amphibians with attenuation of ultraviolet-b radiation in montane ponds Association of amphibians with attenuation of ultraviolet-b radiation in montane ponds
Ambient ultraviolet-b (UV-B) radiation (280–320 nm) has increased at north-temperate latitudes in the last two decades. UV-B can be detrimental to amphibians, and amphibians have shown declines in some areas during this same period. We documented the distribution of amphibians and salmonids in 42 remote, subalpine and alpine ponds in Olympic National Park, Washington, United States. We...

Response of hatchling and yearling turtles to thermal gradients: Comparison of Chelydra serpentina and Trachemys scripta Response of hatchling and yearling turtles to thermal gradients: Comparison of Chelydra serpentina and Trachemys scripta
In laboratory tests, young Chelydra serpentina and Trachemys scripta altered their distribution in the presence of a temperature gradient. Selection of temperatures in the gradient for hatchlings and yearlings showed that body temperatures (Tbs) of C. serpentina were lower than T. scripta, but the difference was insignificant. Relatively low Tbs could allow greater activity range and...

Pond permanence and the effects of exotic vertebrates on anurans Pond permanence and the effects of exotic vertebrates on anurans
In many permanent ponds throughout western North America, the introduction of a variety of exotic fish and bullfrogs (Rana catesbeiana) correlates with declines in native amphibians. Direct effects of exotics are suspected to be responsible for the rarity of some native amphibians and are one hypothesis to explain the prevalence of amphibian declines in western North America. However...

Amphibians of Olympic National Park Amphibians of Olympic National Park
Amphibians evolved from fishes about 360 million years ago and were the first vertebrates adapted to life on land. The word amphibian means "double life." It refers to the life history of many amphibians, which spend part of their life in water and part on land. There are three major groups of amphibians: salamanders, frogs, and toads, and caecilians. Salamanders, frogs, and toads can be...

Correlated factors in amphibian decline: Exotic species and habitat change in western Washington Correlated factors in amphibian decline: Exotic species and habitat change in western Washington
Amphibian declines may frequently be associated with multiple, correlated factors. In western North America, exotic species and hydrological changes are often correlated and are considered 2 of the greatest threats to freshwater systems. Bullfrog (Rana catesbeiana) introductions are frequently cited as a threat to lentic-breeding anurans native to western North America and are a...

Amphibian and reptile surveys of U.S. Navy lands on the Kitsap and Toandos Peninsulas, Washington Amphibian and reptile surveys of U.S. Navy lands on the Kitsap and Toandos Peninsulas, Washington
We inventoried amphibians and reptiles on 5 U.S. Naval holdings located on the Kitsap and Toandos Peninsulas, western Washington. Eight amphibians, including an introduced anuran, and 4 reptiles were detected, resulting in 87 new locality records. Six species were found on the Toandos Peninsula where no previous records exist. Of the species that historically or currently occur on the...
