Salt marshes often contain remarkable spatial heterogeneity at multiple scales across the landscape. A combination of advanced remote-sensing approaches (hyperspectral imagery and lidar) and conventio...
Chemical and agronomical control of volunteer plants is difficult, especially in reduced-input cropping systems where feeding by natural herbivores may become an important cause of their mortality. ...
Growth plays an important roll in the survival of individual salmonid fish. Diet inevitably plays a significant role in the determination of salmonid growth, with these diets consisting primarily of a...

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...
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...
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 ...
Climate warming can affect ecological food chains directly by increasing the rates of physiological processes and indirectly by changing habitat use and altering predator-prey interactions. In Lake Ma...
In the Aleutian Islands, crustose coralline algae can be widespread in the low intertidal and shallow subtidal regions, and cover most available hard substrates. Subtidal habitats dominated by crusto...
Variations in macroinvertebrate drift and benthic invertebrate abundance were assessed in 30 upland Welsh streams of varying acidity (pH < 5.7 or pH.> 6.0) and riparian land-use (conifer, moorland or ...
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...
Invertebrate Survival Journal (ISJ) is an international and open access journal devoted to prompt and innovative studies on the basic defense mechanisms in invertebrates, in particular with a view to ...
Macrobenthic Invertebrate Fauna of Lake Eğrigöl (Gündoğmuş - Antalya).
Elements incorporated into developing hard parts of planktonic larvae record the environmental conditions experienced during growth. These chemical signatures, termed elemental fingerprints, potential...
