Selectivity by planktivorous fish at different prey densities, heterogeneities, and spatial scales
different prey densities heterogeneities spatial scales
2014/4/2
Studies in artificially confined, small-scale experimental systems with a homogeneous prey distribution suggest
that selectivity in planktivorous fish for more conspicuous and rewarding prey (such as...
Patch exploitation by planktivorous fish and the concept of aggregation as an antipredation defense in zooplankton
zooplankton antipredation defense
2014/4/2
Contrary to the suggestion that swarming can be used as an antipredation defense in zooplankton, the
individual risk of a planktonic prey (Daphnia) increased rather than decreased with prey density u...
Climatic forcing of zooplankton dynamics is stronger during low densities of planktivorous fish
Climatic forcing of zooplankton dynamics planktivorous fish
2014/4/18
We analyze interannual variation in zooplankton biomass in the southwestern Barents Sea in spring (May) and
summer (June–July) 1959–1993. Using a threshold modeling approach, we quantify spatial, cli...
Nutrient limitation of primary producers affects planktivorous fish condition
Nutrient limitation planktivorous fish condition
2014/4/22
We investigated whether nutrient limitations of primary producers act upward through food webs only in
terms of density effects or if there is a second pathway for nutrient limitation signals channel...
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...

In this study, Lake Eymir, Eymir inflow 1, Kışlakçı brook and Eymir outflow were sampled monthly betwen March 1997and April 1998 for physico-chemical and biological parameters. W...
