Latest food webs Stories
Managing fish in human-altered rivers is a challenge because their food webs are sensitive to environmental disturbance.
A recent study featuring work by several UC Santa Barbara scientists focuses on the impact parasites have on food webs, with findings that are expected to alter our picture of who-eats-who.
Parasites comprise a large proportion of the diversity of species in every ecosystem.
At first glance, pitcher plants appear to be simple carnivorous plants that entrap and digest hapless insects that fall into them. However, a closer look reveals a complex food web of fly larvae, rotifers, midge larvae, and bacteria that exist within the plants’ pitcher.
Animals like foxes and raccoons are highly adaptable. They move around and eat everything from insects to eggs. They and other “generalist feeders” like them may also be crucial to sustaining biological diversity.
A new study by researchers at the Virginia Institute of Marine Science (VIMS) shows that jellyfish are more than a nuisance to bathers and boaters, drastically altering marine food webs by shunting food energy from fish toward bacteria.
New research shows that nature and humans are leaving an indelible mark on rivers and streams, which are affecting the intricate food webs they support.
Projects address concern for acidifying marine ecosystems.
Findings advance understanding of how complete food webs function.
The findings, published in this week's issue of Science, conclude that food-web stability is enhanced when many diverse predator-prey links connect high and intermediate trophic levels.
