Populationversusspecies data:Most large-scale ecophysiological research is based on modellingonemeasurement of heat tolerance per species (typically representing one population and/or physiological assay) over hundreds to thousands of species covering broad geographical, phylogenetic, and climatic gradients...
. Environmental fate and effects of radiation has ranged from observable DNA damage of the cell to the fare on tissues, individual(s), population (s), community and ecosystems. One of the key issues to judge the benchmark exposures of radiation for environmental protection is : What is the ...
This has created a bias in the ecotoxicology literature that can compromise inferences about effects at higher levels of biological organization such as the population, ecological community, or ecosystem levels. Despite this bias, the methods described herein can and are used pragmatically to infer ...

Community Ecotoxicology Ecotoxicology is the study of the effects of toxicants on ecological systems. Ecological effects of contaminants may occur at several levels of biological organisation, from individual organisms to the entire biosphere. Communities consi...

(n = 2212). Second, we conducted stratified probabilistic sampling. This technique is used to select a sample in each stratum independently, maintaining the representation of the population in each stratum (Thompson2012). The total sample size was determined using the equation in Appendix 1 ...
