On the Trails: Herbivores and their plants

...Ecologists call this an increase of primary productivity, because the basic producers of energy and nutrients for the food web (namely, the plants) have increased. This kind of response to grazing can happen when the system is rich enough to...
To camp or not to camp? lucky we are ... When the salmon goes to sea, only two percent come home. The rest are all gone, part of the food web of Mother Nature. Look at every creature in here, and it's the same story. The quest for life and propagation is...
Study: Manmade carbon may be affecting ocean food web

...carbon can also be exported to ecosystems downstream from glaciers where it can be metabolized and become part of the food web."These findings show that glaciers like Mendenhall can provide us with novel information about how humans are altering...
My Turn: Real oil spill solution long overdue

...the ecosystem to support the many species that rely on it. As the council states, herring "are central to the marine food web providing food to marine mammals, birds, invertebrates and other fish."While the council sponsored many useful studies...
Whales may impact herring stocks' recovery

...whales) is so rich in nutrients that it contributes to the food web whatever it removes. This would mean that when whales eat krill, they actually enrich the food web for the existing herring."It's hard to figure out...

Ocean acidification threatens marine life telling yet if other plankton species are experiencing changes, too.So, to understand the future of the marine food web, government computer modelers have been studying how sea-chemistry changes could reverberate through the ocean. Their...
Revamping the rip rap

...birds, Hudson said. Even the leaf litter is important. "The leaf litter falls into the stream and fuels the benthic food web, where invertebrates process that leaf litter and turn it into insect biomass that then emerge and come back to the riparian...
