Abstract:

Until recently in Earth history, very large herbivores (mammoths, ground sloths, diprotodons, and many others) occurred in most of the World’s terrestrial ecosystems, but the majority have gone extinct as part of the late-Quaternary extinctions. How has this large-scale removal of large herbivores affected landscape structure and ecosystem functioning? In this review, we combine paleo-data with information from modern exclosure experiments to assess the impact of large herbivores (and their disappearance) on woody species, landscape structure, and ecosystem functions.

Abstract:

Contradictory findings among scientific studies that address a particular issue may impede the conversion of science to management implementation. A systematic review of peer-reviewed studies to generate a single outcome may overcome this problem. The contentious topic of the impact that a megaherbivore such as the savanna elephant have for other species and their environment can benefit from such an approach. After some 68 years, 367 peer-reviewed papers covered the topic and 51 of these papers provided sufficient data to be included in a meta-analysis.

Abstract:

Woody encroachment in ‘open’ biomes like grasslands and savannahs is occurring globally. Both local and global drivers, including elevated CO2, have been implicated in these increases. The relative importance of different processes is unresolved as there are few multi-site, multi-land-use evaluations of woody plant encroachment.

Abstract:

The study of collective or group-level movement patterns can provide insight regarding the
socio-ecological interface, the evolution of self-organization and mechanisms of inter-individual
information exchange. The suite of drivers influencing coordinated movement trajectories
occur across scales, resulting from regular annual, seasonal and circadian stimuli and irregular
intra- or interspecific interactions and environmental encounters acting on individuals. Here,
we promote a conceptual framework with an associated statistical machinery to quantify the

Abstract:

Models of wildlife population dynamics are crucial for sustainable utilization and
management strategies. Fluctuating ecological conditions are often key factors influencing
both carrying capacity, mortality and reproductive rates in ungulates. To be reliable,
demographic models should preferably rely on easily obtainable variables that are
directly linked to the ecological processes regulating a population.
