Food web consequences of size-based predation and vertical migration of an invertebrate predator (Leptodora kindtii)
size-based predation an invertebrate predator
2014/4/2
In an intensive study of the vertical and horizontal distribution of zooplankton in a eutrophic lake (Katepwa
Lake), we found that only adult Leptodora kindtii (. 5 mm in body size) exhibited diel ve...
High incidence of invertebrate–chemoautotroph symbioses in benthic communities of the New Zealand fjords
High incidence invertebrate–chemoautotroph symbioses benthic communities the New Zealand fjords
2014/4/16
In the New Zealand fjords, hydrogen sulfide production from decomposing forest litter is used by chemoautotrophs to fix CO2[aq]and support benthic food webs. We used quantitative surveys and stable is...
Two-step dialogue between the cladoceranBosminaand invertebrate predators: Induction and natural selection
Two-step dialogue cladocera Bosmina invertebrate predators: Induction natural selection
2014/4/16
Aquatic prey species respond to predators with fast (developmental) and slow (selective) feedbacks. Natural selection is assumed to fashion details of induction and to modify baseline morphology, but ...
Efficacy of open-ocean ballast water exchange as a means of preventing invertebrate invasions between freshwater ports
open-ocean ballast water exchange preventing invertebrate invasion freshwater ports
2014/4/21
Ballast water is a major vector of nonindigenous species invasion globally. Mandatory ballast water exchange (BWE) was implemented for vessels carrying ballast water into the Great Lakes in 1993. Desp...
Spatial and temporal variation in trace elemental fingerprints of mytilid mussel shells: A precursor to invertebrate larval tracking
Spatial and temporal variation trace elemental fingerprints mytilus mussel shells invertebrate larval tracking
2014/5/8
Elements incorporated into developing hard parts of planktonic larvae record the environmental conditions experienced during growth. These chemical signatures, termed elemental fingerprints, potential...
Evidence for a residual post-glacial founder effect in a highly dispersive freshwater invertebrate
residual post-glacial founder effect highly dispersive freshwater invertebrate
2014/5/14
In the northern hemisphere, glacial periods have had profound and lasting effects on the population genetics of numerous species, with founder effects often persisting for many generations in formerly...
Viability of invertebrate diapausing eggs collected from residual ballast sediment
invertebrate diapausing eggs residual ballast sediment
2014/5/21
Natural or anthropogenic movement of sediments may be an important vector for the dispersal of invertebrate
resting stages between water bodies. Here we record the presence of invertebrate diapausing...
Reach-scale manipulations show invertebrate grazers depress algal resources in streams
Reach-scale manipulations show invertebrate grazers depress algal resources in streams
2014/5/27
Experimental tools that enable manipulations of organisms at larger scales allow for comparisons of processes across multiple spatial scales and expand our ability to make predictions about ecological...
Landscape effects of climate, agriculture, and urbanization on benthic invertebrate communities of Canadian prairie lakes
Landscape effects of climate, agriculture, and urbanization benthic invertebrate communities Canadian prairie lakes
2014/5/26
Paleoecological analyses of fossil chironomid assemblages from eight lakes of the Qu’Appelle Valley, Saskatchewan, Canada, were used to quantify the relative influence of climate, resource use, a...
