Examining shifts in zooplankton community variability following biological invasion
Examining shifts zooplankton community variability following biological invasion
2014/4/2
We examined 20 yr of zooplankton samples from Harp Lake for shifts in zooplankton variability following invasion by zooplankton predator Bythotrephes longimanus, using organism body size—as measured a...
Threshold-driven shifts in two copepod species: Testing ecological theory with observational data
Threshold-driven shifts two copepod species Testing ecological theory observational data
2014/4/2
We used an observed abrupt shift in the dominance pattern of two coexisting copepod species in Müggelsee, a shallow eutrophic lake in Germany, to investigate mechanisms leading to this shift, by embed...
A behavioral cascade: Top-predator induced behavioral shifts in planktivorous fish and zooplankton
Top-predator planktivorous fish zooplankton
2014/5/21
It is well known that the effects of direct (lethal) predator-prey interactions propagate through food webs (the trophic cascade). However, in the present study we show for the first time that, parall...
Shifts in habitat templates for lotic microalgae linked to interannual variation in snowmelt intensity
habitat templates logic microalgae linked interannual variation snowmelt intensity
2014/6/9
We investigated the importance of snowmelt as an organizing factor for epilithic microalgae in a high-altitude montane stream during 3 yr (1995-1997) of differing melt characteristics. Changes in alga...
