The Problem of the Lechwe (Kobus leche) on the Kafue Flats [PDF]
Most of the information in this article refers to the south bank of the Kafue Flats, though much will doubtless be applicable to other areas where lechwe occur. Ansell (1955) refers to the lechwe on the Kafue Flats as “red lechwe”, and it has indeed been customary to apply this term to all lechwe in Northern Rhodesia, except those found on the plains ...

Abstract Invasive species typically establish in areas outside their natural distribution through accidental introduction and accidental release or escape. Some species are introduced legally for economic and social benefits such as recreational hunting, the pet trade and research through established permitting processes driven by appropriate laws and ...

Evolution of ungulate mating systems: Integrating social and environmental factors
We provide a new approach to understanding mating systems in ungulates. We integrate both social and environmental factors in doing so. We develop a predictive model to help understand the evolution of these unique behaviors, which should help to direct future studies.

Infomap Bioregions: Interactive mapping of biogeographical regions from species distributions [PDF]
Biogeographical regions (bioregions) reveal how different sets of species are spatially grouped and therefore are important units for conservation, historical biogeography, ecology and evolution. Several methods have been developed to identify bioregions

Dental functional morphology predicts the scaling of chewing rate in mammals [PDF]
How food intake and mastication scale to satisfy the metabolic needs of mammals has been the subject of considerable scientific debate. Existing theory suggests that the negative allometric scaling of metabolic rate with body mass is compensated by a ...

Foraging investment in a long‐lived herbivore and vulnerability to coursing and stalking predators
Foraging is necessary for herbivores to grow and reproduce, but foraging also causes tooth erosion, which shortens life span. How herbivores negotiate this trade‐off has been primarily explored in systems without large predators. When selecting prey, coursing and stalking carnivores exploit unique vulnerabilities that might arise from variable ...
