because of their positions at the top of food webs. They are some of the world's most …

Large carnivores are frequently presented as saviours of biodiversity and ecosystem
functioning through their creation of trophic cascades, an idea largely based on studies …

During the last century humans have dramatically accelerated alterations and loss of
biodiversity worldwide. Changes to our planet's ecosystems by Humans go back tens of …

Biotic and abiotic factors are increasingly acknowledged to synergistically shape broad-
scale species distributions. However, the relative importance of biotic and abiotic factors in …

INTRODUCTION A surprisingly general pattern at very large scales casts light on the link
between ecosystem structure and function. We show a robust scaling law that emerges …

Background Livestock grazing and 'overabundance'of large wild herbivores in forested
areas have long been perceived as conflicting with the aims of both silviculture and forest …

Wildlife management systems face growing challenges to cope with increasingly complex
interactions between wildlife populations, the environment and human activities. In this …

There is a lack of scientific consensus about how top-down and bottom-up forces interact to
structure terrestrial ecosystems. This is especially true for systems with large carnivore and …

Broad scale population estimates of declining species are desired for conservation efforts.
However, for many secretive species including large carnivores, such estimates are often …

Understanding the interaction among predators and between predation and climate is
critical to understanding the mechanisms for compensatory mortality. We used data from …
