Sensitivity of greenback cutthroat trout to acidic pH and elevated aluminum Sensitivity of greenback cutthroat trout to acidic pH and elevated aluminum
The greenback cutthroat trout Oncorhynchus clarki stomias is a threatened subspecies native to the upper South Platte and Arkansas rivers between Denver and Fort Collins, Colorado, an area also susceptible to acid deposition. In laboratory studies, we exposed this subspecies to nominal pHs of 4.5–6.5 and to nominal aluminum concentrations of 0, 50, 100, and 300 μg/L; the control was pH 6...

Role of exposure mode in the bioavailability of triphenyl phosphate to aquatic organisms Role of exposure mode in the bioavailability of triphenyl phosphate to aquatic organisms
A laboratory study was conducted to investigate the role of the route of triphenyl phosphate (TPP) entry on its aquatic bioavailability and acute biological effects. Three TPP treatments were used for exposures of fish and invertebrates. These consisted of TPP dosed directly into water with and without clean sediment and TPP spiked onto sediment prior to aqueous exposures. Results of...

Geographic and temporal variation in the diet of Yellow-headed Blackbirds Geographic and temporal variation in the diet of Yellow-headed Blackbirds
Yellow-headed Blackbirds (Xanthocephalus xanthocephalus) are presumed predators of sunflower (Helianthus annuus) in the northern Great Plains. Their esophageal contents varied temporally and among three provinces and three states in relation to regional agricultural bases but males contained more sunflower and small grains than females whereas females contained more weed seeds and...

H4IIE rat hepatoma cell bioassay-derived 2,3,7,8-tetrachlorodibenzo-p-dioxin equivalents in colonial fish-eating waterbird eggs from the Great Lakes H4IIE rat hepatoma cell bioassay-derived 2,3,7,8-tetrachlorodibenzo-p-dioxin equivalents in colonial fish-eating waterbird eggs from the Great Lakes
Fish-eating waterbirds from the Great Lakes of North America have shown symptoms of poisoning similar to those observed in laboratory exposures of various avian species to planar halogenated hydrocarbons (PHHs). PHHs, include among others, polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs), and polychlorinated dibenzofurans (PCDFs) and have been implicated in...

The measurement of mangrove characteristics in southwest Florida using spot multispectral data The measurement of mangrove characteristics in southwest Florida using spot multispectral data
An intensive in situ sampling program near Marco Island, Florida during 19–23 October 1988 collected information on mangrove type, maximum canopy height, and percent canopy closure. These data were correlated with selected vegetation index information derived from analysis of SPOT multispectral (XS) data obtained on 21 October 1988. The Normalized Difference (ND) vegetation index...

Decreased survival of rainbow trout exposed to no. 2 fuel oil caused by sublethal preexposure Decreased survival of rainbow trout exposed to no. 2 fuel oil caused by sublethal preexposure
Rainbow trout (Oncorhynchus mykiss) were exposed for 21 d to sublethal levels of No. 2 fuel oil (2FO). The four exposure concentrations ranged from 12 to 100 mg/L 2FO dispersed in water and resulted in 0 to 12% mortality. Following this exposure period (preexposure) the ability of preexposed trout to survive exposure to acutely lethal levels of 2FO was observed. Preexposure to either 50...
