The type of impact depends on the
herbivore, with possums becoming markedly more ground-active and frequently damaging or killing trees, and all
herbivores inhibiting canopy tree seedling recruitment.
Due to those large-bodied
herbivores (nature's grass and brush mowers) wildfires were infrequent, relatively small with low intensity and short-lived; nothing like the catastrophic wildfires we are experiencing today.
urticae, is a polyphagous
herbivore of great economic importance in many crops, having a host range of more than 1,100 species of plants (Grbic et al., 2011).
Table 2 shows the number of cattle and wild
herbivore events in each land-use type used in the analysis.
2006) or
herbivore numbers (Letourneau & Barbosa 1999), facilitating effective pollination (Oliveira 1997; Holland et al.
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?
Experimental manipulation of predation risk and food quality: effect on grazing behaviour in a central-place foraging
herbivore.--Oecologia 146: 157-167.
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., 2010; Fritz et al., 2011).
In turn, fire influences patterns of
herbivore selection of forage sites, as plant nutrient content, digestibility, and the availability of forage plants can temporarily increase following burning (Carlson et al., 1993; Mixon et al., 2009).
For the dataset of
herbivore stress, we classified our data into Asteraceae, Fabaceae, Plantaginaceae, Poaceae, and Rosaceae; for the dataset of nematode stress, we classified our data into Asteraceae, Cucurbitaceae, Fabaceae, Malvaceae, Oleaceae, Passifloraceae, Poaceae, Rosaceae, Rutaceae, Solanaceae, and Vitaceae; for the dataset of fungal pathogen stress, we classified our data into Cucurbitaceae, Fabaceae, Lamiaceae, Malvaceae, Poaceae, Rosaceae, Rutaceae, and Solanaceae.
The researchers' experiments were conducted using a control group (consisting of grass and perennial herbs only), a plant and
herbivore group (which included grasshoppers), and a plant,
herbivore and carnivore group (which included spiders).
Herbivore feeding guilds may thus respond differently to the same habitat conditions due to, mainly, level of specialization and life history constraints (Denno & Roderick 1991, Vehvilainen et al.
