1998, Book chapter, Status and trends of the nation's biological resources
Rocky Mountain elk are native to northcentral New Mexico, including the Jemez Mountains, whereas a different subspecies, Merriam’s elk, inhabited southern New Mexico, east-central Arizona, and the Mexican border region (Hall 1981). Merriam’s elk went extinct around 1900 in New Mexico, and native Rocky Mountain elk were extirpated by 1909...
Similar rates of decrease of persistent, hydrophobic and particle-reactive contaminants in riverine systems
Peter C. Van Metre, Jennifer T. Wilson, Edward Callender, Christopher C. Fuller
1998, Environmental Science & Technology (32) 3312-3317
Although it is well-known that concentrations of anthropogenic radionuclides and organochlorine compounds in aquatic systems have decreased since their widespread release has stopped in the United States, the magnitude and variability of rates of decrease are not well-known. Paleolimnological studies of reservoirs provide a tool for evaluating these long-term trends...
Movement patterns and the conservation of amphibians breeding in small, temporary wetlands
C.K. Dodd Jr., B.S. Cade
1998, Conservation Biology (12) 331-339
Many amphibians breed in water but live most of their lives in terrestrial habitats. Little is known, however, about the spatial distribution of these habitats or of the distances and directions amphibians move to reach breeding sites. The amphibian community at a small, temporary pond in northcentral Florida was monitored...
