Our understanding of the long-lasting effects of human land use on soil fungal communities in tropical forests is limited. Yet, over 70% of all remaining tropical forests are growing in former agricultural or logged areas. We investigated the relationship among land use history, biotic and abiotic factors, and soil fungal community composition and diversity in a second-growth tropical forest in...
Serpentine is formed during chemical transformation of ultrabasic magmatic rocks. The characteristics of serpenti ne soi l are its high Mg and low Ca contenI. Various factors have lead to the formation of specific serpentine flora and vegetation. In the serpentine flora both basophi10us and acidophilous plant species are present, and a small number of families and often genera predominate. Most...

the effect of planted saltbush (atriplex lentiformis) on edaphic factors in grazed and ungrazed area
re-vegetation of bare soil is believed to increase, or at least maintain the organic matter levels of soil. the aim of this study was to investigate the soil characteristics changes, nutrient pool sizes and their availability under mid canopy, and canopy gap positions of saltbush in an area re-vegetated with atriplex lentiformis. some of the physical and chemical soil characteristics (the parti...
