Regional geochemistry of rubber plantation in Hainan Island, China
The geochemical characteristics of the soils and economic crops on Hainan Island are different from place to place. Formulation of an overall planning is urgently required for the development of agriculture, including the cultivation of rubber

Micrometeorological characteristics of a rubber plantation on Hainan Island, China
In this paper, the micrometeorological characteristics of rubber tree stands, heat balance, radiative and aerodynamic properties are analyzed with data for three years (April 1986 to March 1989).

Cost-return analysis of the substitution of food crops for rubber in the small holder cropping system of Southern Nigeria : a case study of Bendel State
Monetary return food crops enterprise compares favourably with returns from other economic activities while that from rubber does not. It is estimated that by 1991 rubber plantations may be eliminated in this study area if the present trend

Case studies of the sediment record in the Atlantic for two species of planktonic Foraminifera, left-coiling Neogloboquadrina pachyderma (Ehrenberg) and Globigerinoides ruber (d'Orbigny), illustrate seasonal bias in environmental data reported
by the relative abundances of species in deep-sea sediments. In addition, the study of G. ruber illustrates the operation of two oceanographic parameters in controlling a species distribution. These examples demonstrate that the environmental signal

Disappearance of pink-pigmented Globigerinoides ruber at 120,000 yr BP in the Indian and Pacific Oceans
The planktonic foraminiferal species Globigerinoides ruber with pink-pigmented tests occupied a worldwide warm water belt during much of the Pleistocene. This variety was exterminated from the Indian and Pacific Oceans at about 120,000 yr BP, based

and the results extrapolated over large, inaccessible areas. This technique is applied to part of the Rub' Al Khali in the northern United Arab Emirates. Trend surface analysis of the results suggests that the sand sea at this location can be modelled as an east

Rubber plantation and its relationship with topographical factors in the border region of China, Laos and Myanmar
The AA. examine the rubber plantation and its relationship with topographical factors in the border region of China, Laos and Myanmar. They show that for the period of time study, it expanded further in all directions with Jinghong City
as the center. Also, a great proportion of rubber plantation concentrated in the appropriate elevation gradients between 600 and 1000 m. They also demonstrate that there in an increase in area at higher elevations and steeper slopes in China, while there were
large appropriate topographical gradients for rubber plantation in Laos and Myanmar which benefited China for rubber trans-boundary expansion.

Tubing on the Apple River: a new industry ?

The Apple River in northwest Wisconsin, USA, has become popular as a place to float downstream in the clean water on rubber tubes. A new recreational activity has had a significant economic impact on the local area. - (DWG)
