Emerging directions in freshwater food-web research involve integrating individual-level variation and information on traits into food-web studies. This is allowing a growing understanding of the ways in which food webs can be used to integrate community, evolutionary and population processes into ...
A freshwater food web model for the combined effects of nutrients and insecticide stress and subsequent recovery. ( 2004 ). “ A freshwater food web model for the combined effects of nutrients and insecticide stress and subsequent recovery .” Environmental toxicology ... TP Traas,JH Janse,PJ ...
Recent efforts to clarify how food web interactions differ from food chain interactions have emphasized the various, often subtle, repercussions of top predators on communities. Predators can modify community structure not only through directly imposed death rates, but also through direct and indirect ...
Isotopic analysis of three food web theories in constricted and floodplain regions of a large river Analyses of stable isotope (未13C and 未15N) and C:N ratios of food webs within a floodplain and a constricted-channel region of the Ohio River during Octo......
Trophic transfer of metals along freshwater food webs: Evidence of cadmium biomagnification in nature.We conducted a study with cadmium (Cd) and copper (Cu) in the delta of San Francisco Bay, using nitrogen and carbon stable isotopes to identify trophic position and food web structure. Cadmium ...
This data set presents a comprehensive food web for Quick Pond, a northern California pond ecosystem. The web includes organisms from all regions of the pond (i.e., littoral, limnetic, profundal, and benthic zones) as well as terrestrial organisms that interact with the aquatic community or ha...
RATIONALEDorsal white muscle is the standard tissue analysed in fish trophic studies using stable isotope analyses. However, sampling white muscle often implies the sacrifice of fish. Thus, we examined whether the non-lethal sampling of fin tissue can substitute muscle sampling in food web studies....
Food webIkpoba RiverPesticidesThe study assessed pesticide contamination transfer in Ikpoba River, an important tropical freshwater ecosystem in Southern Nigeria. The study quantified concentrations, bioaccumulation and biomagnification of pesticides in Ikpoba River's food web, with emphasis on less ...
Food web typologyPlanktonSpring bloomWater renewalAnthropogenic controlWe conducted a weekly survey at two stations of a French coastal marsh during the transition from winter to spring, when the sea lock gates were closed. Field measurements and laboratory experiments were combined in order to ...
food webs in certain regions of the estuary (Howe and Simenstad2007; Grimaldo et al.2009; Howe and Simenstad2011; Schroeter et al.2015), little is known about the trophic support provided by different habitat types in the North Delta. Elucidating the food web structure of this region is ...
