-damaged seeds were counted as any seeds with obvious herbivore
damage, along with empty seed chambers that contained seed debris.
A post hoc LSD test revealed that the ash content (%) of herbivore
, carnivore and omnivores were significantly different from each other (Fig.
Scenario two: trophic rewilding What would happen if instead of just abandoning the land, populations of large herbivores
such as bison, wild horse, European elk (aka moose) or wild boar were established, along with their predators lynx, wolf and bear?
Our results provide a functional basis for using PSMs, specifically monoterpenes, as predictors of suitable habitats and use for a specialist mammalian herbivore
The Mana floodplain has been severely impacted over the years by large herbivores
, and the Exclosure--clearly visible from the air and in satellite imagery--lies a few hundred metres to the southeast of Nyamepi camp; it is visible on the right from the road between Nyamepi and Mana river mouth.
Recent studies have explored the interplay between environmental gradients, herbivore
body size, and predation pressure in several savanna ecosystems (Beauchamp, 2010; Hopcraft et al.
Even in low numbers, the presence of one or a few species of herbivores
can lead to higher leaf damage (Coley and Barone, 1996), since even low abundance in a herbivore
is able to spend more time in the plant and feeding access a large number of plants when it finds its natural enemy, increasing your damage (Beckerman et al.
damage and plant characteristics were recorded for the five legume species.
The aim of this study was to investigate how forest canopy structure affects insect herbivore
species richness and abundance depending on feeding guilds' specificities.
Key words: diet, Erethizon dorsatum, facultative specialist, generalist, herbivore
, nutrition, Porcupine, selectivity
are therefore crucial for the seed dispersal of many plants, as they either drop or regurgitate their food, or defecate later on.
Deer, elk and other big herbivores
cause surprisingly extensive damage to forests and streams when their populations surge as a result of killings of their natural predators such as wolves and bears, says a new study by two Oregon State University professors.
