Climate-Associated Regime Shifts Drive Decadal-Scale Variability in Recovery of North Atlantic Right Whale Population
Climate-Associated Decadal-Scale Variability North Atlantic Right Whale Population
2015/7/20
Despite an elevated mortality rate from lethal interactions with humans, the North Atlantic right whale population has continued to grow during the first decade of the new millennium. This unexpected ...
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...
Shifts in limiting nutrients in an estuary caused by mixing and biological activity
limiting nutrients mixing biological activity
2014/4/8
Simple general equations are used to show that when riverine water mixes with seawater, the N : P ratio is a
nonlinear function of salinity. Thus, a shift in the limiting-nutrient status at a particu...
Temporal dynamics of seston: A recurring nighttime peak and seasonal shifts in composition in a stream ecosystem
A recurring nighttime peak seasonal shifts
2014/4/17
We measured the baseflow concentration and composition of seston and suspended particulate organic carbon
(POC) over a 1-yr period in White Clay Creek, a third-order stream in the southeastern Pennsy...
Frequent regime shifts in trophic states in shallow lakes on the Boreal Plain: Alternative ‘‘unstable’’ states?
trophic states shallow lakes
2014/4/22
Shallow lakes are known to exhibit alternative states in their biotic structure. Lakes dominated by submersed
aquatic vegetation (SAV) are ‘‘clear,’’ while lakes dominated by algae (high concentratio...
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...
Mysis relicta in a eutrophic lake: Consequences of obligatory habitat shifts
Mysis relicta eutrophic lake obligatory habitat shifts
2014/5/20
Low numbers of mysids in eutrophic lakes have usually been related to their poor tolerance to low oxygen. In eutrophic Lake Hiidenvesi, we studied the possibility that water quality indirectly affects...
Climatic warming causes regime shifts in lake foodwebs
Climatic warming regime shifts lake food webs
2014/6/10
Spring clear water phases caused by grazing of zooplankton on algae are among the most spectacular and well-studied events in lake plankton dynamics. Such clear water phases are also important as wind...
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...
