Soil biodiversity means the range of creatures, various shapes and sizes, living in soils—from microorganisms to animals. diversity is extremely important and, protect it, we need know where potentially endangered soil organisms live. Unfortunately, do not have data on distribution most species. However, potential threats soils inhabitants. Therefore, identify areas risks are high try reduce th...

abstract soil contamination by heavy metals is yet one of the most important environmental concerns. among heavy metals, nickel and cadmium have dangerous influences on human, animals and plants. the objective of this study was to derive a new model for simultaneous phytoextraction of ni and cd from contaminated soils. consequently, a macroscopic model was derived by combining yield reduction f...

In behavioral experiments using monochromatic prey-patterns, larval salamanders (Salamandra salamandra) are able to discriminate colored from white light. In the retina only blue-yellow opponent-color ganglion cells were recorded. Thus the color vision in these animals is dichromatic.

Relationships between soils and their position in the landscape have been well established in most parts of the world. Such relationships are useful when mapping soils and geographically identifying soil classes based on a set of diagnostic soil characteristics and horizons. Human infl uence may alter the pattern, and here we report on a series of soilscapes in Wisconsin, USA that have been str...

A territorial isolation is a danger to the game population, causing deterioration called the inbreeding depression. The typical signs are anomalous body proportions, such as short lower jaw, shortened lifetime, weak physique and lower birth rate. This is caused by low number of game in the community. White colored deer is in the location of the CzechRepublicbred in separation since 18th century...

Introduction Nematodes are tiny, worm-like, multicellular animals adapted to living in water. The number of nematode species is estimated at half a mil lion, many of which are “free-living” types found in the oceans, in freshwater habitats, and in soils. Plant-parasitic species form a smaller group. Nematodes are common in soils all over the world (Dropkin, 1980; Yepsen, 1984). As a commentator...
