Polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and nonand mono-ortho-substituted polychlorinated biphenyls (dioxin-like PCBs) was analyzed in earthworms, plants, insects, field mouse and birds collected in Kanagawa Prefecture and their accumulation in the terrestrial ecosystem was studied. TEQ was highest in raptor species and followed by mouse liver, other bir...
we examined the diet and trophic level of sphyrna lewini in the gulf of california (gc) during 2001 and in the gulf of tehuantepec (gt) during 2005 using data from stomach content and stable isotope analysis of δ15n and δ13c. s. lewini diet was represented by pelagic and benthic prey species where the most important in weight was scomber japonicus (27.70±4.54%) in gc, while in gt it was auxis s...
Detritivory is the dominant trophic paradigm in most terrestrial, aquatic, and marine ecosystems, yet accurate measurement of consumer trophic position within detrital (="brown") food webs has remained unresolved.
