- Abstract:
- ... Assessments of environmental impacts are being subject to greater scientific and legal scrutiny than ever before. The application of traditional statistical decision‐making criteria to questions of environmental impacts has become increasingly inadequate as society demands greater environmental accountability from economic development. In particular, impact assessment has inherited a preoccupation ...

- Abstract:
- ... The basic claims of The Bell Curve are contradicted. Studies are reviewed indicating that consensus does not exist that IQ tests measure intelligence. When sociocultural environment was held constant, differences in measured intelligence between groups were not present. Claims of 60% within group heritability are based on twin studies where a significant number of separated twins were reared in si ...

This dimension is additional to purely environmental and socio-economic considerations in the election of specific environmental objectives and instruments. Given the vague and complex nature of most environmental problems, the 'environment' is easily deployed as a vehicle for transferring power from the nation ...

The other three are social pressure, regulations, and division of the resource into private sections. In theory, having a common resource used exclusively by a community, rather than by private parties, eliminates the personal profit motive, thereby opening up possibilities for more ...

A large body of literature, both theoretical and applied, has grown up over the years proposing a variety of options and methods for internalising environmental costs. However, most of these theories and metho ...

With increase in temperature the gammaLnn content was found to increase along with biomass. The optimum temperatu ...

The foraminiferal content of seven piston and three vibrocores were analysed. Radiocarbon dates were obtained from four of the cores. Relatively warm water masses occurred in the shallow a ...

- Abstract:
- ... The main purpose of this study was to monitor exposure to lead and cadmium in wild birds in Murcia, a southeastern region of Spain on the Mediterranean coast. This region lies on one of the African-European flyways. Samples of liver, kidney, brain, bone, and whole blood from several species of wild birds were obtained during 1993. We found a clear relationship between cadmium and lead concentratio ...

- Abstract:

The development and distribution of Northern mires, including minerotrophic fens and ombrotrophic raised bogs, frequently are presumed to be strongly controlled by the interplay of regional climate and site geomorphology and history. Investigations of these relationships provide insights into long—term trends in ecosystem development by linking geological and landscape—scale processes. In this stu ...

Migratory white-throated sparrows (Zonotrichia albicollis) were exposed to acephate (acetylphosphoramidothioic acid O,S-dimethyl ester), an organophosphorus pesticide, to determine its effects on migratory orientation and behavior. Birds were also exposed to polarizer sheets to determine the mechanism by which acephate may affect migratory orientation. Adult birds exposed to 256 ppm acephate a.i. ...

Because studies of environmental accidents must be initiated after the fact and because the accidents cannot (or should not) be replicated, sampling cannot be entirely randomized, and investigations involve some degree of confounding and pseudoreplication. The study designs that can be used carry methodological limitations and ecological assumptions, which must be considered in evaluating results. ...

In this paper we explore the hypothesis that the accumulation of environmental pressures, including erosion, salinization, soil exhaustion, and degradation of the local environment, may be partially responsible ...

Enriching the environment through the use of foraging devices has been one method and a study was designed to evaluate the short-term effect of a new foraging device on singly-housed cynomolgus monkeys. The study was divided into 3 one- ...

Neither breed was affected by stable fly feeding from 85 d u ...

We studied the acclimation of plants from alpine or lowland areas and asked two questions: (1) do plants acclimate to a change in temperature and does acclimation depend on the plants' origin: and (2) have alpine plants adapted to low ...

During the 36 h of measurement, significant changes were seen in walked distance, mean velocity, and turning rate. It is concluded that these end points provide a sensitive measure of toxic stress. ...
