Partition and adsorption on soil and mobility of organic pollutants and pesticides
The mechanism for sorption of organic pollutants and pesticides by soil has long been a subject of profound interest because of its direct impacts on the mobility and activity of the compounds in soil. Although a large volume of laboratory and field data on many aspects of soil behavior had been gathered between the 1950s and 1970s, during which period the use of organic pesticides was increased,

Rice prairies
Pesticide contamination of rice prairie waterfowl habitat and acute pesticide poisoning of wintering and migrating waterfowl on the rice prairies has been reduced in recent years. Some problems still exist.

Thermal and cementation histories of Permian shelf-edge carbonate rocks in the Nanpanjiang Basin, South China
As of 1984, the Nanpanjiang Basin of South China has had almost no exploration by drilling although oil seeps exist among its margins and producing wells occur in adjacent basins. however, cooperative studies by petroleum geologists and geochemists of the United States and the People's Republic of China (1982-1984) show that calcite-cemented reef and fore-reef carbonate rocks near Ziyun contain b

Gopherus agassizii: Desert tortoise
The desert tortoise is one of four allopatric North American tortoises. It occurs in the Mojave and Sonoran deserts of the southwestern United States and Mexico.Auffenberg (1976) divided the genus Gopherus (consisting of four species, G. agassizi, G. berlandieri, G.flavomarginatus, and G. polyphemus) in two osteological groups. Bramble (1982), using morphological and palaeontological data, divided

A coded tracking telemetry system
We describe the general characteristics of an automated radio telemetry system designed to operate for prolonged periods on a single frequency. Each transmitter sends a unique coded signal to a receiving system that encodes and records only the appropriater, pre-programmed codes. A record of the time of each reception is stored on diskettes in a micro-computer. This system enables continuous mo

Aerial tracking of radio-marked white-tailed tropicbirds over the Caribbean Sea
We radio-marked nesting white-tailed tropicbirds at Culebra National Wildlife Refuge, Puerto Rico, and tracked them from a Cessna 182 during flights over the open sea. Locations of the birds were determined using standard aerial telemetry techniques for side-facing Yagi antennas. We used strut-mounted, 4-element Yagi antennas connected to a switchbox and scanning receiver. By recording bearing

Anadarko Basin conodont studies
Preliminary analysis of early Paleozoic conodonts from the subsurface within and adjacent to the Anadarko basin demonstrates their utility in stratigraphic and thermal evolution studies in the basin. More than 100 samples from 30 drill holes produced conodonts that can be correlated with faunas known from rock sequences exposed along the southern flanks of the basin. For the Middle Ordovician to D
