The Return of the Giants: Ecological Effects of an Increasing Elephant Population
TLDR
Investigating the interactions between the increasing elephant population and other ecosystem components and processes in northern Botswana confirms that the ecosystem is changing following the increase in elephant and ungulate populations, and developing towards a situation resembling that before the reduction of large herbivores.
Methods for Locating African Lion Kills Using Global Positioning System Movement Data
TLDR
Implementation of GLMs within an adaptive sampling framework can considerably increase efficiency of locating kill sites, providing a cost-effective method for increasing sample sizes of kill data.
Functional significance of ungulate diversity in African savannas and the ecological implications of the spread of pastoralism
TLDR
In selected regions where potential still exists, African savanna biodiversity and human economic development will both be best served by the integration of sustainable wildlife utilization into multispecies animal production systems.
Coexistence between People and Elephants in African Savannas
Abstract: The decline in the range and numbers of elephants as a result of expanding human activity in Africa is recognized as one of the continent’s more serious conservation problems. Understanding
Body Size, Population Metabolism, and Habitat Specialization Among Large African Herbivores
TLDR
Results are presented confirming that among African savanna herbivores, population metabolism scales positively with body mass, and a hypothesis is presented to explain this, on the basis of patterns of habitat use.
Estimating carnivoran diets using a combination of carcass observations and scats from GPS clusters.
TLDR
It is shown that an approach that supplements carcass observations with scats that enables the identification of potentially missed feeding events increases the estimates of food intake rates for large carnivorans, with possible ramifications for predator-prey interaction studies dealing with biomass intake rate.
Generalities in grazing and browsing ecology: using across-guild comparisons to control contingencies
TLDR
One trophic guild is used as a “control” for the other to identify generalities that are not contingent upon specific consumer-resource interactions to resolve contingencies in community processes.
Sustaining Natural and Human Capital: Villagers and Scientists
Community-based natural resource management (CBNRM) is a rural development paradigm that combines biological conservation and sustainable use of natural resources. In southern Africa, CBNRM has
Translocation stress and faecal glucocorticoid metabolite levels in free-ranging African savanna elephants
TLDR
It is found that translocation resulted in a significant increase in faecal glucocorticoid metabolite levels compared to pre-translocation levels in this group, and levels measured in undisturbed ‘control’ groups in the area.
Winning by a Neck: Tall Giraffes Avoid Competing with Shorter Browsers
TLDR
It is concluded that giraffes preferentially browse at high levels in the canopy to avoid competition with smaller browsers, providing the first experimental support for the classic evolutionary hypothesis that vertical elongation of the giraffe body is an outcome of competition within the browsing ungulate guild.
