Synthesizing the effects of large, wild herbivore exclusion on ecosystem function
Wild large herbivores are declining worldwide. Despite extensive use of exclosure
experiments to investigate herbivore impacts, there is little consensus on the effects of wild …

Determinants of woody encroachment and cover in African savannas
Savanna ecosystems are an integral part of the African landscape and sustain the
livelihoods of millions of people. Woody encroachment in savannas is a widespread …

[ספר][B] Trophic cascades: predators, prey, and the changing dynamics of nature
J Terborgh, JA Estes - 2013 - books.google.com
Trophic cascades—the top-down regulation of ecosystems by predators—are an essential
aspect of ecosystem function and well-being. Trophic cascades are often drastically …

Herbivore-initiated interaction cascades and their modulation by productivity in an African savanna
Despite conceptual recognition that indirect effects initiated by large herbivores are likely to
have profound impacts on ecological community structure and function, the existing …

A meta‐analysis of the impact of African elephants on savanna vegetation
Large herbivores such as elephants (Loxodonta africana) apparently have a negative
impact on woody vegetation at moderate to high population densities. The confounding …

Native ungulates of diverse body sizes collectively regulate long‐term woody plant demography and structure of a semi‐arid savanna
Large mammalian herbivores are well recognized to play important roles in regulating
woody cover and biomass in savannas, but the extent to which browsing ungulates are …

Large herbivores may alter vegetation structure of semi-arid savannas through soil nutrient mediation
In savannas, the tree–grass balance is governed by water, nutrients, fire and herbivory, and
their interactions. We studied the hypothesis that herbivores indirectly affect vegetation …

[ספר][B] The ecology of browsing and grazing
About fifty years ago, when I, as a young comparative anatomist, first looked at a wild
ruminant–the European roe deer–the basic thinking concerning the ecology, behaviour …

Cascading consequences of the loss of large mammals in an African savanna
African savannas are home to an abundant and diverse assemblage of wild herbivores, but
the very grasses that sustain these wild herds also make savannas attractive to humans and …

[ספר][B] Ecology of woodlands and forests: description, dynamics and diversity
P Thomas, J Packham - 2007 - books.google.com
Taking a functional rather than an ecosystem or a utilitarian approach, Thomas and
Packham provide a concise account of the structure of woodlands and forests. Using …
