New lithological and whole rock compositional data show that the main platinum-group element (PGE) horizons of the Flatreef succession show strong compositional similarities to the Merensky and Bastard reefs of the western Bushveld Complex (WBC), notably in terms of many immobile and incompatible minor and trace elements such as TiO 2 , Zr, Y, and REE. However, Al 2 O 3 , CaO, and Na 2 O contents are markedly lower in the Flat...

Despite widespread recognition of the major threat to tropical forest biological diversity and local food security posed by unsustainable bushmeat hunting, virtually no long‐term studies tracking the socioecological dynamics of hunting systems have been conducted. We interviewed local hunters and collected detailed hunting data to investigate changes in offtake and hunter characteristics over 10 years (2001–2010) in Dibouka an...

Bushmeat hunting is an activity integral to rural forest communities that provides a high proportion of household incomes and protein requirements . An improved understanding of the relationship between bushmeat hunting and household wealth is vital to assess the potential effects of future policy interventions to regulate an increasingly unsustainable bushmeat trade . We investigated the relationship between hunting offtake a...

We investigated temporal changes in hybridization and introgression between native red deer ( Cervus elaphus ) and invasive Japanese sika ( Cervus nippon ) on the Kintyre Peninsula, Scotland, over 15 years, through analysis of 1513 samples of deer at 20 microsatellite loci and a mtDNA marker. We found no evidence that either the proportion of recent hybrids, or the levels of introgression had changed over the study period. Nev...

Mandrills ( Mandrillus sphinx ) are forest primates indigenous to western central Africa. Phylogenetic analysis of 267 base pairs (bp) of the cytochrome b gene from 53 mandrills of known and 17 of unknown provenance revealed two phylogeographical groups, with haplotypes differentiated by 2.6% comprising seven synonymous transitions. The distribution of the haplotypes suggests that the Ogooué River, Gabon, which bisects their r...

A methodology is described for measuring the opinions of rural people who are affected by water‐related development and conservation projects. The method is illustrated by results from three applications of the methodology at sites in Sri Lanka. Aspects of the technique, the preparation of questionnaires, and the analysis of findings, are discussed. Copyright © 2001 John Wiley & Sons, Ltd.
