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.
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)
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.
Following the previous report on this subject, published in 2007, there has been a very substantial increase in publications relevant to landscape ecology. The continuing identity crisis of landscape ecology is described and recent literature
in the field is then summarized under the following headings : Landscape ecology and climate research; Alternatives to fragmentation and the patch-based model - the links between pattern and process; Fragmentation research; Methodology and techniques
in landscape ecology; and Connectivity and graph theoretical approaches. The review concludes that landscape ecology now represents one important focus within biogeography, linked to ecological biogeography, and takes its place alongside other key foci

the coastal sites of the plant. However there are differences between the coastal and inland growing sites : electrolyte content, chemical analyses of the plants. Thus the occurrence in Kuusamo poses several ecological and palaeoecological problems.
of spatio-temporal changes in the fluvial response, the assessment of the system as one of the last untapped regional palaeo-ecological archives, and the chronological integration into the existing climato-stratigraphic models of the southwestern Chad Basin
. A lithostratigraphical data base was created and supplemented by age determinations. The morphogenetic information was derived from palaeo-geographical and -hydrological interpretations of diverse remote sensing data.

on the archaeological record from this period; and then to identify broad spatial and temporal trends in human adaptations of this period, and assess the manner in which foragers responded to those climatic, ecological, and hydrological conditions.
This paper assesses the preservation of biogenic isotopic composition of the collagen fraction of mammal bone and tooth from the uppermost well-defined layer of the cave (numbered 1A) and determines the ecological basis for interspecific differences
. The objectives of this paper are to reconstruct Holocene environmental changes in this ecotonal region using multiple paleoecological data and to discuss the ecological mechanism and driving factors of Holocene desertification in southeastern Inner Mongolia.

What is surprising, especially as we observe the development of biogeography over the last decade or so, is that macro-problems are increasingly being answered by micro-methods. Just as biology and ecology are increasingly moving into and drawing
