Vertical mixing processes and thermal structure of large lakes can impact the biological processes both through vertical transport processes and the exponential decay of light with depth. I investigated the role of these issues in algal consumption, production and influence on oxygen dynamics. The impact of a benthic filter feeder limited by physical transport of algae to the benthos. Hydrodyna...

• We studied bathymetric zonation of benthos in the Central Arctic over a depth range spanning 14–5416 m. Our analyses indicated faunal boundaries at depths 650–950 m and 2600–3000 m, delineating sublittoral bathyal fauna abyssal faunas, respectively. original previously published data collectively suggest uniform patterns overturn benthic assemblages throughout entire continental slope plain. ...

Lake Tanganyika’s many endemic species are under threat by impacts from human development and land use changes. Anthropogenic sediment inputs into the lake have increased, with a suite of negative effects on the benthic fauna. Sedimentation reduces habitat heterogeneity, alters cycling of nutrients, interferes with visibility, and interferes with photosynthesis. For fauna of the rocky benthos, ...

We examined the habitat of juvenile haddock on the eastern Scotian Shelf (off Nova Scotia, Canada) in relation to grab-sampled benthic macrofaunal invertebrate species assemblages in order to determine whether there were significant differences in benthic macrofauna between areas of historically persistent high and low juvenile haddock abundance. Our analyses were conducted over two spatial sca...
