Primary production: Terrestrial ecosystemsSpringer Science and Business Media LLC - Tập 1 - Trang 303-332 - 1973
Helmut Lieth
The history of growth in understanding of primary productivity and in making estimates of biosphere production is reviewed. Two approaches to estimation of land production are discussed. Production may first be estimated by mean values for ecosystem types and the areas of these. A total production of 100×10
9 tons/year is thus estimated for the continents, making up 29% of the earth's surface. Th...... hiện toàn bộ

Wild yams revisited: Is independence from agriculture possible for rain forest hunter-gatherers?Springer Science and Business Media LLC - Tập 19 - Trang 213-243 - 1991
Serge Bahuchet, Doyle McKey, Igor de Garine
The hypothesis that energy-rich wild plant foods are too scarce in rain forest to allow subsistence by foraging peoples independently of agriculture lacks a firm empirical basis. Data on availability of wild plant foods such as wild yams are sorely lacking, and where quantitative information is provided to support the hypothesis, it usually concerns extent of use of wild plant foods: low availabi...... hiện toàn bộ
