International trade in ivory is banned in order to protect the African elephant. The trade ban is supported by some range states, because it is seen as an effective means for protecting a ‘flagship’ species, but is opposed by states, mainly in southern Africa, because populations exceed the carrying capacity of local ecosystems. Issues concerning the ivory trade ban are addressed in this paper ...

THE PREVAILING INCREASE IN ELEPHANT numbers across areas of southern Africa raises concern for their impact on biological diversity. Several approaches to elephant management focus on limiting numbers to alleviate these consequences. However, landscape fragmentation, fences, water supplementation as well as the shape and size of some conservation areas restrict range use and intensify the effec...

Africa can stir wild and fanciful notions in the casual visitor; one of these is the tale of inebriated wild elephants. The suggestion that the African elephant (Loxodonta africana) becomes intoxicated from eating the fruit of the marula tree (Sclerocarya birrea) is an attractive, established, and persistent tale. This idea now permeates the African tourist industry, historical travelogues, the...

BACKGROUND In marine pelagic ecosystems, the spatial distribution of biomass is heterogeneous and dynamic. At large scales, physical processes are the main driving forces of biomass distribution. At fine scales, both biotic and abiotic parameters are likely to be key determinants in the horizontal and vertical distribution of biomass, with direct consequences on the foraging behaviour of diving...

Parasitic lice (order Phthiraptera) infest birds and mammals. The typical animal mitochondrial (mt) genome organization, which consists of a single chromosome with 37 genes, was found in chewing lice in the suborders Amblycera and Ischnocera. The sucking lice (suborder Anoplura) known, however, have fragmented mt genomes with 9-20 minichromosomes. We sequenced the mt genome of the elephant lous...

Increasingly, habitat fragmentation caused by agricultural and human development has forced Sumatran elephants into relatively small areas, but there is little information on how elephants use these areas and thus, how habitats can be managed to sustain elephants in the future. Using a Global Positioning System (GPS) collar and a land cover map developed from TM imagery, we identified the habit...

We provide here unique data on elephant skeletal ontogeny. We focus on the sequence of cranial and post-cranial ossification events during growth in the African elephant (Loxodonta africana). Previous analyses on ossification sequences in mammals have focused on monotremes, marsupials, boreoeutherian and xenarthran placentals. Here, we add data on ossification sequences in an afrotherian. We us...

An understanding of the interaction between spittlebugs and forage grasses is essential for establishing factors that favor productive pastures. In the present study, we evaluated the protein profiles of the spittle of Mahanarva spectabilis (Distant, 1909) (Hemiptera: Cercopidae) fed various elephant grass genotypes. Each plant was infested with a single fifth-instar M. spectabilis. After 24 h,...
