Patrick M Kleeman
Patrick Kleeman is a Supervisory Ecologist at the Western Ecological Research Center.
Patrick Kleeman's research focuses on the ecology and conservation biology of amphibians. Topics of study within these categories include population demography through capture-mark-recapture methods, habitat use by using radiotelemetry, and phenology of breeding as evidenced by vocalizations. His research also examines what role stressors such as environmental contaminants, disease, and climate may have on amphibian populations. In addition to amphibians, he also works with island night lizards (Xantusia riversiana) on San Nicolas Island and Townsend's big-eared bats (Corynorhinus townsendii) at Point Reyes National Seashore.

Wetland occupancy of pond-breeding amphibians in Yosemite National Park, USA Wetland occupancy of pond-breeding amphibians in Yosemite National Park, USA
We estimated wetland occupancy and population trends for three species of pond-breeding anurans in Yosemite National Park from 2007-2011. We used a double survey technique in which two observers independently surveyed each site on the same day. Double surveys allowed us to calculate detectability for the three most common anurans within the park: Rana sierrae, Anaxyrus canorus, and...

Pesticides in amphibian habitats of Central and Northern California, USA Pesticides in amphibian habitats of Central and Northern California, USA
Previous studies have indicated that toxicity from pesticide exposure may be contributing to amphibian declines in California and that atmospheric deposition could be a primary pathway for pesticides to enter amphibian habitats. We report on a survey of California wetlands sampled along transects associated with Lassen Volcanic National Park, Lake Tahoe, Yosemite National Park, and...

A network extension of species occupancy models in a patchy environment applied to the Yosemite toad (Anaxyrus canorus) A network extension of species occupancy models in a patchy environment applied to the Yosemite toad (Anaxyrus canorus)
A central challenge of conservation biology is using limited data to predict rare species occurrence and identify conservation areas that play a disproportionate role in regional persistence. Where species occupy discrete patches in a landscape, such predictions require data about environmental quality of individual patches and the connectivity among high quality patches. We present a...

Accumulation of pesticides in pacific chorus frogs (Pseudacris regilla) from California's Sierra Nevada Mountains, USA Accumulation of pesticides in pacific chorus frogs (Pseudacris regilla) from California's Sierra Nevada Mountains, USA
Pesticides are receiving increasing attention as potential causes of amphibian declines, acting singly or in combination with other stressors, but limited information is available on the accumulation of current-use pesticides in tissue. The authors examined potential exposure and accumulation of currently used pesticides in pond-breeding frogs (Pseudacris regilla) collected from 7 high...

Expression analysis and identification of antimicrobial peptide transcripts from six North American frog species Expression analysis and identification of antimicrobial peptide transcripts from six North American frog species
Frogs secrete antimicrobial peptides onto their skin. We describe an assay to preserve and analyze antimicrobial peptide transcripts from field-collected skin secretions that will complement existing methods for peptide analysis. We collected skin secretions from 4 North American species in the field in California and 2 species in the laboratory. Most frogs appeared healthy after release...
