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.

Site and Survey Data for Amphibian Surveys in Yosemite National Park, 2018 Site and Survey Data for Amphibian Surveys in Yosemite National Park, 2018
These data represent occupancy surveys conducted in long-term monitoring sites in Yosemite National Park in 2018 for three anurans, the Yosemite Toad (Anaxyrus canorus), the Sierran Treefrog (Pseudacris sierra), and the Sierra Nevada Yellow-legged Frog (Rana sierrae). The data include independent double-observer surveys and time-to-detection data to calculate detection probabilities and...
Code and Data to Fit an Integrated Population Model for the Foothill Yellow-legged Frog, Rana boylii, in Northern California Code and Data to Fit an Integrated Population Model for the Foothill Yellow-legged Frog, Rana boylii, in Northern California
These data include egg mass counts and adult capture-mark-recapture histories for Foothill Yellow-legged frogs (Rana boylii) at two streams in northern California. Data were collected from the South Fork Eel River and its tributary, Fox Creek, from 1993-2019. Data from Hurdygurdy Creek were collected from 2002-2008. This code and data support the following publication: Rose, JP...

This dataset provides the results of a national survey of the conterminous U.S. for the salamander chytrid fungus Batrachochytrium salamandrivorans (Bsal) conducted by the U.S. Geological Survey Amphibian Research and Monitoring Initiative from May 2014 to August 2017. Sites were sampled by capturing amphibians by hand or by traps or nets that were then swabbed individually using methods...
Time to detection data for Point Reyes pond-breeding amphibians, 2017 Time to detection data for Point Reyes pond-breeding amphibians, 2017
Occupancy models provide a reliable method of estimating species distributions while accounting for imperfect detectability. The cost of accounting for false absences is that detection and nondetection surveys typically require repeated visits to a site or multiple-observer techniques. More efficient methods of collecting data to estimate detection probabilities would allow additional...
Occurrence of Amphibians in Northern California Coastal Dune Drainages Occurrence of Amphibians in Northern California Coastal Dune Drainages
Many coastal dune ecosystems have been degraded by non-native dune vegetation, but these systems might still provide valuable habitat for some taxa, including amphibians. Because restoration of degraded dune systems is occurring and likely to continue, we examined the occurrence of amphibians in drainages associated with a coastal dune ecosystem degraded by invasive plants (European...

Time-to-detection occupancy methods: Performance and utility for improving efficiency of surveys Time-to-detection occupancy methods: Performance and utility for improving efficiency of surveys
Occupancy methods propelled the quantitative study of species distributions forward by separating the observation process, or the imperfect detectability of species, from the ecological processes of interest governing species distributions. Occupancy studies come at a cost, however: the collection of additional data to account for nondetections at sites where the species is present. The...

Batrachochytrium salamandrivorans (Bsal) not detected in an intensive survey of wild North American amphibians Batrachochytrium salamandrivorans (Bsal) not detected in an intensive survey of wild North American amphibians
The salamander chytrid fungus (Batrachochytrium salamandrivorans [Bsal]) is causing massive mortality of salamanders in Europe. The potential for spread via international trade into North America and the high diversity of salamanders has catalyzed concern about Bsal in the U.S. Surveillance programs for invading pathogens must initially meet challenges that include low rates of...

Monitoring protocol development and assessment for narrowly endemic toads in Nevada, 2018 Monitoring protocol development and assessment for narrowly endemic toads in Nevada, 2018
Several species and subspecies of toads are endemic to small spring systems in the Great Basin, and their restricted ranges and habitat extent make them vulnerable to environmental perturbations. Very little is known about several of these toad populations, so a group of stakeholders including the U.S. Geological Survey, U.S. Fish and Wildlife Service, Bureau of Land Management, Nevada...

Effect of amphibian chytrid fungus (Batrachochytrium dendrobatidis) on apparent survival of frogs and toads in the western USA Effect of amphibian chytrid fungus (Batrachochytrium dendrobatidis) on apparent survival of frogs and toads in the western USA
Despite increasing interest in determining the population-level effects of emerging infectious diseases on wildlife, estimating effects of disease on survival rates remains difficult. Even for a well-studied disease such as amphibian chytridiomycosis (caused by the fungus Batrachochytrium dendrobatidis [Bd]), there are few estimates of how survival of wild hosts is affected. We applied

Linking variability in climate to wetland habitat suitability: Is it possible to forecast regional responses from simple climate measures? Linking variability in climate to wetland habitat suitability: Is it possible to forecast regional responses from simple climate measures?
Temporary wetlands have value to both ecological and social systems. Interactions between local climate and the surrounding landscape result in patterns of hydrology that are unique to temporary wetlands. These seasonal and annual fluctuations in wetland inundation contribute to community composition and richness. Thus, predicting wetland community responses to environmental change is...
