The tiny shrimp-like creatures are one of the most important in the Antarctic food web
, eaten by species ranging from blue whales to Adelie, emperor and king penguins, elephant and fur seals and albatrosses.
Finding that methane and other forms of mostly invisible dissolved organic matter are the foundation of the food web
in these caves explains why cave-adapted animals are able to thrive in the water column in a habitat without visible evidence of food.
Nagelkerken's research, she said,"is not a prediction of the future, but it is nice proof that we can expect food web
reorganisation with continued ocean warming and acidification.
Thompson and colleagues discuss in some detail the relationship between food web
size (which is tightly correlated with species richness) and resolution.
Six SFOS researchers, along with staff, students, and international collaborators, will study oceanography and food web
dynamics in the northern Bering Sea and southern Chukchi Sea through the North Pacific Research Board's Arctic integrated Ecosystem Research Program with fieldwork in early spring 2017 and 2018.
Follow the lines of this food web
to see what they eat in each season.
This suggests a significant reduction or even possible loss of the ecological function of top predators, especially those at the adult stage, which could impact, in the short or medium term, the structure of the food web
in the study area.
structure, mediated by spatial and habitat differences, was examined in a subtropical estuary using stomach content and stable isotope analyses.
They export fish and invertebrate larvae, they influence the productivity of the sea grass bed through grazing and nutrient export and migrate adult fishes and invertebrates, and they export organic material and nutrients supporting the pelagic food web
There is potential for these carbonaceous particulates to enter watersheds and have deleterious effects on aquatic food web
Variation in food web
structure has been linked to a variety of trophic level and productivity patterns associated with freshwater communities (Carpenter et al.
Changes generally are driven by organisms at the bottom of the food web
called primary producers: the diatoms and other copious single-celled organisms that are grazed upon by small creatures.
