Population structure, body mass, activity, and orientation of an aquatic snake (Seminatrix pygaea) during a drought Population structure, body mass, activity, and orientation of an aquatic snake (Seminatrix pygaea) during a drought

The snout – vent length, tail length, weight, sex, activity, and orientation of a population of swamp snakes (Seminatrix pygaea) in north – central Florida were recorded from 1985 through 1990. A small temporary pond was monitored for 1343 days, using a drift fence – pitfall trap sampling regime. I captured 123 different snakes, plus 45 recaptures. Juveniles comprised 89% of the snakes...

Use of mesocosm data to predict effects in aquatic ecosystems: Limits to interpretation: Chapter 16 Use of mesocosm data to predict effects in aquatic ecosystems: Limits to interpretation: Chapter 16

Aquatic mesocosm studies are being used to refute a presumption of risk derived from laboratory toxicity tests conducted under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Mesocosm studies incorporate many biological, chemical and physical characteristics of natural ecosystems. Hence, they serve as realistic surrogates of natural ecosystems and allow tests of...

Ground-water conditions in Pecos County, Texas, 1987 Ground-water conditions in Pecos County, Texas, 1987

A comparison of 1987 water levels with historical (1940-49) water levels in the Edwards-Trinity (Plateau) aquifer indicated that water levels declined more than 50 feet in three locations in the Leon-Belding irrigation area, in an area north of Fort Stockton, and in a well east of Bakersfield. Maximum measured declines were 54 and 82 feet in the Leon-Belding irrigation area. The maximum...

Hydrogeologic framework of U.S. Marine Corps Base at Camp Lejeune, North Carolina Hydrogeologic framework of U.S. Marine Corps Base at Camp Lejeune, North Carolina

The hydrogeologic framework at Camp Lejeune consists of the surficial, Castle Hayne, Beaufort, and Peedee aquifers and intervening confining units. The Castle Hayne aquifer furnishes about 7 million gallons of water per day to Camp Lejeune, but the surficial, Beaufort, and Peedee aquifers, which contain freshwater in places, are not used for supply. The Castle Hayne aquifer is composed...

Reconnaissance investigation of the geology and hydrogeology of Lackland Air Force Base, San Antonio, Texas Reconnaissance investigation of the geology and hydrogeology of Lackland Air Force Base, San Antonio, Texas

An investigation at Lackland Air Force Base and Lackland Air Force Base Training Annex (Medina Base) was conducted from May to September 1988 to delineate the subsurface geology, to describe the hydrogeology within the study area, and to determine possible migration pathways for contaminants. Data from this investigation supplement data collected in conjunction with other Air Training...
