The purpose of this paper is to discuss the significance of magnetotactic bacteria with respect to biomineralization, ecology, sediment magnetism, and their potential use as environmental indicators.
A new attempt at an ecological classification of land utilization systems
Classification ; Ecology ; Farming system ; Farming;Agriculture ; Land use ; Nutrient ; Taxonomy
After a brief review of previous classifications, the A. advocates an approach for an ecologically-based classification of utilization systems, consisting of two elements : one describing the productive environment, and the other describing the main

The A. concludes, that during the interglacial periods of the Pleistocene, though as a function of the current macro-climatic features, but in a given period regionally highly differentiated ecological conditions were characteristics, like today
. Landscape ecological studies also show that the anthropogenic interventions generate occasionally completely new environmental conditions. - (JS)
This review begins with a brief summary of the biology, taxonomy and ecology of ostracods. It then reviews recent research on Quaternary nonmarine ostracods, and outlines some of the more important literarure on the subject.
Behaviour ; Ecology ; Environment ; Man-environment relations ; Perception ; Social theory
The A. starts by documenting development of environment-based theories such as those which focus upon ecology, environmental learning, and the influence of societal structures. He explores the person-environment integration that may be found
