Sentences with phrase «herbivore populations»

A wild tomato plant, Solanum peruvianum, from field - study sites in the Rio Fortaleza Valley in the Ancash Province of Peru.The modeling study suggests that the herbivore - induced release of protective chemical compounds limits population growth of both the pollinator and the flowering plant, thereby temporarily and indirectly restricting the growth of herbivore populations and preventing extinction.

These patterns in turn may have implications for future C cycling and sequestration in tropical forests, as changes in environmental conditions lead to shifts in abundances of herbivore populations.

The modeling study suggests that the herbivore - induced release of protective chemical compounds limits population growth of both the pollinator and the flowering plant, thereby temporarily and indirectly restricting the growth of herbivore populations and preventing extinction.

Some of those studies predicted extinctions because growing herbivore populations would reduce the number of plants, limiting resources available to pollinators.

When it comes to non-native plants that are congeners — non-native plants with a close native relative, such as Norway maple and red maple — the researchers found that those seem to support herbivore populations across sites more similar to those on natives than the non-native plants that have no native relatives at all.

One of these, brought on by declines in herbivore populations on reefs, is a tendency to shift from dominance by live corals to dominance by macroalgae.

Glaum and Kessler developed a computer model showing that decreased growth of individual plants can benefit overall populations and community resilience by indirectly controlling herbivore population growth.

Not exact matches

Ashwin Alankar of Janus Henderson published his latest article «Brace for Steeper Yield Curves as the Wolves Return,» which highlighted grey wolf's role in maintaining a delicate balance in Yellowstone's ecosystem by keeping population of herbivores in - check, which in - turn reduced risks of overgrazing of young brush and trees in the park.

Building on his field studies of African herbivores, Owen - Smith develops a new modeling approach for studying the population dynamics of large mammals.

The researchers built a complex series of mathematical models to recreate the dynamic interaction between the main potential drivers of extinction (dingoes, climate and humans), the long - term response of herbivore prey, and the viability of the thylacine and devil populations.

Without large grazing herbivores to eat them, acacia trees suffer because of a shift in the ant populations they house

But Glaum and Kessler reached a different conclusion when they included herbivore - induced pollinator limitation (HIPL) in their model, which allowed them to examine broader, more indirect effects of herbivory on plant population persistence and community dynamics.

The Architecture of a Trophic Cascade: Predator - Herbivore - Vegetation When HSS formulated their hypothesis, the scientific community commonly accepted that bottom - up processes, mostly related to competition between species, were the primary forces shaping populations.

Current paradigms generally assume that increased plant nitrogen (N) should enhance herbivore performance by relieving protein limitation, increasing herbivorous insect populations.

Then, and as a consequence of this, there are native to Cedros herbivores, which on one hand compete with the goat population for food and presumably have kept it from increasing beyond carrying capacity, and on the other hand forced the native plants to keep their defenses against herbivores, unlike plants on megaherbivoreless islands which tend to lack those defenses.

They keep the population of certain benthic (sea floor) herbivores, particularly sea urchins, in check.

Herbivores are released from their usual population regulation, leading to over-grazing of kelp and other algae.
