Acting through links between four trophic levels and across two ecosystems, purple loosestrife altered life in nearby ponds
A new study has found that each step of the marine food chain is clearly controlled by the trophic level below it – and the driving factor influencing that relationship is not the abundance of prey, but how that prey is distributed.
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.
Catalan researchers have studied the marine trophic network in Mauritania, on the north west coast of Africa, which is an extremely heavily exploited fishing area, as well as being home to two of the world's most threatened species of marine mammal â€“ the monk seal and the Atlantic hump-backed dolphin.
A measure widely advocated as a means of assessing the health of marine ecosystems is an ineffective guide to trends in biodiversity, and more direct monitoring is needed, a new study has found.
The most widely adopted measure for assessing the state of the world's oceans and fisheries led to inaccurate conclusions in nearly half the ecosystems where it was applied.
The most widely adopted measure for assessing the state of the world's oceans and fisheries led to inaccurate conclusions in nearly half the ecosystems where it was applied according to new analysis by an international team led by a University of Washington fisheries scientist.
People who fish for a living pursue top profits, not necessarily top predators.
One of the main objectives of marine biology is to understand the trophic food chains involving microbian plankton.
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.
