Nitrogen loading from developed watersheds to aquatic ecosystems can stimulate microbial denitrification, a
process that reduces nitrate (NO{

We measured the concentration and the stable isotope ratios of dissolved oxygen in the water column in the Estuary and Gulf of St. Lawrence to determine the relative importance of pelagic and benthic ...

We estimated the contributions of sedimentation and cell lysis to the loss of two large phytoplankton species
(Fragilaria crotonensis and Staurastrum dorsidentiferum) in Lake Biwa. Major loss process...
Siliceous sponges as a silicon sink: An overlooked aspect of the benthopelagic coupling in the marine silicon cycle
Siliceous sponges silicon sink bathypelagic coupling marine silicon cycle

2014/5/9
Our current understanding of the silicon (Si) cycle in the ocean assumes that diatoms dominate not only the uptake of silicic acid, but also the production and recycling of biogenic silica (BSi), and ...
To sink or swim: Variable diapause strategies among Daphnia species

2014/5/16
Although dormancy is assumed to be fundamental to population persistence in temporary ponds, it has been
suggested that diapause may be less frequent in populations that inhabit permanent lakes. We c...
