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.

California Red-Legged Frogs in Point Reyes Coastal Dune Drainages (2015) California Red-Legged Frogs in Point Reyes Coastal Dune Drainages (2015)
California Red-legged Frogs (Rana draytonii) are typically regarded as inhabitants of permanent ponds, marshes, and slow-moving streams, but their ecology in other habitats, including coastal dunes, remains obscure. To avoid and minimize potential negative effects of dune restoration activities, we studied the spatial ecology, habitat selection, and survival of California Red-legged...

Distribution, habitat, and population size of Island Night Lizards on San Nicolas Island, California Distribution, habitat, and population size of Island Night Lizards on San Nicolas Island, California
The Island Night Lizard (Xantusia riversiana) was removed from the federal list of threatened species in May 2014. This strongly differentiated species is endemic to 3 of the southern California Channel Islands—San Clemente, San Nicolas, and Santa Barbara. Suitable habitat for Island Night Lizards is extensive on San Clemente Island, and the species is abundant there. Habitat is limited...

Quantifying climate sensitivity and climate-driven change in North American amphibian communities Quantifying climate sensitivity and climate-driven change in North American amphibian communities
Changing climate will impact species’ ranges only when environmental variability directly impacts the demography of local populations. However, measurement of demographic responses to climate change has largely been limited to single species and locations. Here we show that amphibian communities are responsive to climatic variability, using >500,000 time-series observations for 81...

Population trends, survival, and sampling methodologies for a population of Rana draytonii Population trends, survival, and sampling methodologies for a population of Rana draytonii
Estimating population trends provides valuable information for resource managers, but monitoring programs face trade-offs between the quality and quantity of information gained and the number of sites surveyed. We compared the effectiveness of monitoring techniques for estimating population trends of Rana draytonii (California Red-legged Frog) at Point Reyes National Seashore, California...

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...

Frogs on the beach: Ecology of California Red-legged Frogs (Rana draytonii) in coastal dune drainages Frogs on the beach: Ecology of California Red-legged Frogs (Rana draytonii) in coastal dune drainages
California Red-legged Frogs (Rana draytonii) are typically regarded as inhabitants of permanent ponds, marshes, and slow-moving streams, but their ecology in other habitats, such as drainages among coastal dunes, remains obscure. Because coastal dune ecosystems have been degraded by development, off-highway vehicle use, stabilization, and invasive species, these unique ecosystems are the...

Large-scale recovery of an endangered amphibian despite ongoing exposure to multiple stressors Large-scale recovery of an endangered amphibian despite ongoing exposure to multiple stressors
Amphibians are one of the most threatened animal groups, with 32% of species at risk for extinction. Given this imperiled status, is the disappearance of a large fraction of the Earth’s amphibians inevitable, or are some declining species more resilient than is generally assumed? We address this question in a species that is emblematic of many declining amphibians, the endangered Sierra...
