Veteran trees are keystone structures and play vital roles in ecosystems. Tree hollows, which filled with a mix of leaves wood that is transformed by the biotic community into mould, represent an important microhabitat. hollow communities consist three major groups organisms: microbes, mesofauna (nematodes, mites springtails) macrofauna (beetles, millipedes other insects). Little known about in...

The Corn an important role in agriculture, and can be used both human animal food, production of ethanol, medicines glue. However, is verified cultivation practices soil inappropriate management have led to deterioration. Thus, the importance vegetation cover incorporation organic matter these cultivated soils. objective this work was evaluate effect Carnauba bagana maintained on as mulch incor...

Biodiversity and distribution of benthic Meiobenthos in the sediments of the Southern Caspian Sea) Mazandaran) was studied in order to introduce and determine their relationship with the environmental factors. From 12 stations (ranging in depths 5, 10, 20 and 50 meters), sediment samples were gathered in four seasons (2012). Environmental factors of water near the bottom including temperature, ...

Cover crops and reduced tillage are two elements of conservation agriculture with potential to support larger more diverse soil biological communities. Soil macrofauna can be indicators quality regulate multiple functions, but their response cover crop adoption in temperate regions is not well studied. We evaluated communities related metrics a 16-year winter trial located the San Joaquin Valle...

The Albian- Cenomanian (Kazhdumi Formation) sediments from northeast of Shiraz, Zagros Basin, represents a carbonate sedimentary succession and contain diverse gastropods and bivalves. Detailed studies on 80 samples of invertebrate macrofauna on two stratigraphic sections led to recognized 2 species and 5 genera of gastropods and 7 species and 13 genera of bivalves assemblages. The abscence of ...

Soil is the most basic resource for sustainable agricultural production; it promotes water quality, is a key component of the biogeochemical cycles and hosts a huge diversity of organisms. However, we are not paying enough attention to soil degradation produced by land use. Modern agriculture has been successful in increasing yields but has also caused extensive environmental damage, particular...
