dissolved organic matter dynamics A review
2014/4/17
The biochemical composition of dissolved organic matter (DOM) strongly influences its biogeochemical role in
freshwater ecosystems, yet DOM composition measurements are not routinely incorporated int...
Interspecies differences in calcium content and requirement in four freshwater cladocerans explained by biokinetic parameters
Interspecies differences in calcium content in four freshwater cladocerans explained biokinetic parameters
2014/4/17
We tested the hypothesis that cladocerans with higher calcium (Ca) content are more susceptible to Ca limitation by conducting life table experiments using four cladoceran species with contrasting Ca ...
We examined the dispersal of larvae (glochidia) of a common unionid mussel species, Actinonaias ligamentina,
which need to attach to a host fish in order to develop into juveniles, in a lowland river...
