Analysis of Phenolic Plant Metabolites
TLDR
The formation, structure and nomenclature of phenolic compounds, and the importance of phenolics in ecological studies - past and future. Expand
Determinants of Variation in Tropical Forest Primate Biomass: New Evidence from West Africa
TLDR
It is argued that a wide range of environmental factors affect primate population densities, and that nutrient-poor soils and high tannin levels in tree foliage do not necessarily produce a low primate (or colobine) biomass, as some earlier studies had suggested. Expand
Food selection by two South-east Asian colobine monkeys (Presbytis rubicunda and Presbytis melalophos) in relation to plant chemistry.
TLDR
The biochemical profiles of the young leaf diet of these two monkeys were compared with previously published information on two African and one south Indian colobines and showed marked similarities between different animals, considering contrasts in their habitats. Expand
A critical analysis of techniques for measuring tannins in ecological studies
TLDR
It is concluded that whilst the overall level of phenolics in extracts can be estimated with some confidence the information imparted by more specific assays is very dependent on the procedures employed, particularly when dealing with extracts from taxonomically highly diverse sources. Expand
Food selection by the South Indian leaf-monkey, Presbytis johnii, in relation to leaf chemistry
TLDR
Additional data on mature leaf petioles and young leaves suggest that the high ratio of cell-sap to cell-wall in these items, and their related high digestibility, explain the high relative abundance of these items in the P. johnii diet. Expand
Dietary and foraging strategies of baboons.
TLDR
This paper develops and test multivariate models of the basis of diet selection for populations of montane and savannah baboons and indicates convergence on lower degrees of variation than exist in superficial foodstuff profiles. Expand
A comparison of the floristics and leaf chemistry of the tree flora in two Malaysian rain forests and the influence of leaf chemistry on populations of colobine monkeys in the Old World
A comparative floristic survey of lowland tropical rain forest at Kuala Lompat, Krau Game Reserve, West Malaysia and at Sepilok Virgin Jungle Reserve, Sabah, East Malaysia, revealed significant… Expand
Food selection by black colobus monkeys (Colobus satanas) in relation to plant chemistry
TLDR
It is proposed that relative importance of digestion-inhibitors, low nutrient content and toxins as constraints on food selection by generalist herbivores will vary greatly among forests with different nutrient and secondary chemistry profiles. Expand
Potent antimalarial activity of the alkaloid nitidine, isolated from a Kenyan herbal remedy
TLDR
Bioassay-guided fractionation of extracts of Toddalia asiatica, a plant used by the Pokot tribe of Kenya to treat fevers, has yielded the alkaloid nitidine as the major antimalarial component, and results show a lack of cross-resistance between chloroquine and nitidine. Expand
The influence of topography and soil phosphorus on the vegetation of Korup Forest Reserve, Cameroun
All living trees (≥30 cm gbh) were enumerated in 135 80×80 m plots, each subdivided into four 40×40 m subplots, and arranged along four 5 km transect lines in the Korup Forest Reserve, Cameroun. For… Expand
