The A. discusses the application of landscape ecological principles to a specific and pressing issue: nature reserve design and functioning. He reviews 5 landscape ecological themes with relevance to reserve design and management. He studies
: the role that landscape ecological theories may have in integrating existing principles from applied biogeography and population biology; the unique insights provided by a landscape ecological approach. Finally, he argues that biogeographers need to be more
active in the development and advancement of landscape ecological theory.
Medical-ecological problems of the eastern Aral-land
Aral Region ; Drinking water ; Ecological catastrophe ; Ecosystem ; Epidemiology ; Former USSR ; Health ; Hydrology ; Pesticide ; Pollution ; Salinity ; Soviet Central Asia ; Water quality
The Aral region is taken as an example of a region of ecological disaster. The processes and phenomena of people's health deterioration caused by the deformation of the environment in connection with hydrological changes are discussed. The situation
in Aral region is regarded as a model of large-scale ecological disaster with a medical-ecological dominant.
Ecological perspectives on rock surface weathering: towards a conceptuual model

A wide range of information is now available on the ecology of rock surface microorganisms and lichens and their role in weathering in particular locations. External environmental conditions as well as rock characteristics determine the type of rock
This article endeavours to show how indices used for estimating biodiversity in ecology may also be employed to determine the diversity of soil landscapes.
Brief ecological description of the Dakata valley, a granitic mountainous area in the Harerge region. It is an elephant sanctuary believed to contain most of the last 300 individuals of the endemic subspecies, Loxondonta africana orleansi. Somali
ecological factors, namely: soil type, air humidity, temperature and vegetation. Based on temporal change in dominance, palaeoecological periods were discerned.

The current ecological crisis in the Aral basin is a result of a number of factors, including specific features of the history of economic actvity of the local population. Interaction of sedentory farmers of oases and nomads of steppes and deserts
This study conducted above 3700 m at Piedras Blancas in the northwestern Venezuelan Andes examined variation of soils and the micro-distribution of two paramo species of plants. Results indicated that the greatest geo-ecological impact on rosette
The agroforestry system is an organic combination of agriculture and forestry, ecology and economy, product variation and scientific management. The AA. point out that agroforestry system can be divided into different structural levels. The benefits
of four kinds of structures are compared. The hedge row agroforestry system on slopeland is an effective way to realize coordinate development of ecology and economy.

This article discusses the development of predictive vegetation mapping especially in the context of remote sensing-based vegetation mapping. The A. will illustrate the dependence of predictive vegetation mapping on ecological niche theory, and show
