Charles Drost
Charles Drost's work focuses on biological inventory studies and on the population status, population dynamics, and population genetics of a wide variety of animal species.
Most of this work has been on threatened or rare species on lands managed by Federal agencies in the southwest U.S., including the southern California Channel Islands and on National Park lands in California, Arizona, New Mexico, and Utah. Many of the concerns of conservation and land management are focused on the population status, habitat relationships and, ultimately, long-term protection and restoration of plant and animal species. Charles Drost works on biological inventory studies and on the population status, population dynamics, and population genetics of a wide variety of animal species. Most of these studies are on threatened or rare species on lands managed by Federal agencies. Inventory studies have covered the southern California Channel Islands, National Park lands in the Southwest, and the southwestern states as a whole, as part of the National GAP program. Current studies include:
- Amphibian populations and amphibian declines, particularly the northern leopard frog, in the U.S. Southwest.
- Population ecology and population trends of the island night lizard on the California Channel Islands.
- Inventories, population status and distribution, and habitat relationships of rare land snails in the southern California coastal region and offshore islands.

Biogeographic and ecological regulation of disease: Prevalence of Sin Nombre virus in island mice is related to island area, precipitation, and predator richness
The relative roles of top-down and bottom-up forces in affecting disease prevalence in wild hosts is important for understanding disease dynamics and human disease risk. We found that the prevalence of Sin Nombre virus (SNV), the agent of a severe disease in humans (hantavirus pulmonary syndrome), in island deer mice from the eight California Channel Islands was greater with increased precipitatioAuthorsJohn L. Orrock, Brian F. Allan, Charles A. DrostMammal Inventory of the Mojave Network Parks-Death Valley and Joshua Tree National Parks, Lake Mead National Recreation Area, Manzanar National Historic Site, and Mojave National Preserve
This report describes the results of a mammal inventory study of National Park Service units in the Mojave Desert Network, including Death Valley National Park, Joshua Tree National Park, Lake Mead National Recreation Area, Manzanar National Historic Site, and Mojave National Preserve. Fieldwork for the inventory focused on small mammals, primarily rodents and bats. Fieldwork for terrestrial smallAuthorsCharles A. Drost, Jan HartStatus of the Island Night Lizard and Two Non-Native Lizards on Outlying Landing Field San Nicolas Island, California
More than 900 individually marked island night lizards (Xantusia riversiana) were captured on San Nicolas Island, California, between 1984 and 2007 as part of an ongoing study to monitor the status of this threatened species. Our data suggest that at least a few lizards are probably more than 20 years old, and one lizard would be 31.5 years old if it grew at an average rate for the population. AgeAuthorsGary M. Fellers, Charles A. Drost, Thomas G. MurpheyVascular Plant and Vertebrate Inventory of Montezuma Castle National Monument
Executive Summary We summarize past inventory efforts for vascular plants and vertebrates at Montezuma Castle National Monument (NM) in Arizona. We used data from previous research to compile complete species lists for the monument and to assess inventory completeness. There have been 784 species recorded at Montezuma Castle NM, of which 85 (11%) are non-native. In each taxon-specific chaAuthorsCecilia A. Schmidt, Charles A. Drost, William Lee HalvorsonFood habits of the southwestern willow flycatcher during the nesting season
The food habits and prey base of the endangered Southwestern Willow Flycatcher (Empidonax traillii extimus) are not well known. We analyzed prey remains in 59 fecal samples from an intensively-studied population of this flycatcher at the Kern River Preserve in southern California. These samples were collected during the nesting season in 1996 and 1997 from adults caught in mist nets, and from nestAuthorsCharles A. Drost, Eben H. Paxton, Mark K. Sogge, Mary J.

Non-native plants and animals have become part of our surroundings, in cities, agricultural areas, and wildlands. While there are many beneficial purposes for non-native animals, such as for food and sport hunting and as agricultural animals, the introduction of some has had major negative economic consequences (Palmer 1899), and adverse effects on native wildlife, plants, and habitats.
