Scientific meeting raises awareness of amphibian decline in Asia Scientific meeting raises awareness of amphibian decline in Asia
Blood samples from 433 Peregrine Falcons (Falco peregrinus) during fall and spring migrations, 1976-80, indicated that most of their pesticide burden, primarily DDE, was accumulated on wintering grounds in Latin America. DDE in spring migrants returning from Latin America for the first time declined significantly from 1979 to 1980. Only about 10% of breeding-age females contained...

Variability of bed mobility in natural, gravel‐bed channels and adjustments to sediment load at local and reach scales Variability of bed mobility in natural, gravel‐bed channels and adjustments to sediment load at local and reach scales
Local variations in boundary shear stress acting on bed‐surface particles control patterns of bed load transport and channel evolution during varying stream discharges. At the reach scale a channel adjusts to imposed water and sediment supply through mutual interactions among channel form, local grain size, and local flow dynamics that govern bed mobility. In order to explore these...

Preliminary observations of the behavior of male, flat-tailed horned lizards before and after an off-highway vehicle race in California Preliminary observations of the behavior of male, flat-tailed horned lizards before and after an off-highway vehicle race in California
Animal movements are influenced by many factors, including he need for food and other resources necessary for survival; searching for mates or nest and brood sites; and response to stress, including escape from predators and environmental extremes. Although it is often difficult to determine the exact cause for particular movements by animals, movement, nonetheless, reflects an organism...

Estimating the magnitude of decline of the Florida torreya (Torreya taxifolia Arn.) Estimating the magnitude of decline of the Florida torreya (Torreya taxifolia Arn.)
Torreya taxifolia is a coniferous tree that is endemic to the 35 km stretch of bluffs and ravines along the east side of the Apalachicola River in northern Florida and adjacent southern Georgia. This formerly locally abundant tree declined during the 1950s and 1960s as a result of disease and is currently on the US Endangered Species list. For sparsely distributed species it can often be...
