Biochar or charcoal has a porous physical structure, and thus increases oxygen diffusion into the soil and creates aerobic conditions providing a suitable habitat for aerobic soil microorganisms, and potentially reducing the activity of anaerobic denitrifying bacteria.
Biologists find new genetic interdependence between mothers and their offspring October 2, A team of biologists has discovered that the distinctive genetic processes of early development help explain patterns of animal development in nature and across the evolutionary tree.
Each identification method has disadvantages. A large number of research papers have been published regarding the diversity studies of earthworms using molecular markers where, the emphasis was given on the individual markers.
Shylesh Chandran et al. That is because the level of public understanding of benefits provided by biodiversity is still inadequate Van Noordwijk and Hairiah, The diversity and distribution of terrestrial earthworms in Sakaerat environmental research station and adjacent areas, Nakhon Ratchasima, Thailand.
Ecosystem processes are the changes or reactions occurring in an ecosystem, such as, for instance, biophysical processes decomposition, production, nutrient cycling, energy, and nutrient fluxes Crossman et al.
The study focusing on agricultural intensification at 60 places of four European countries with different climate and soil types showed that areas with highly intensive land management have lower diversity and biomass of soil organisms including earthworms than areas with lower agricultural intensity De Vries et al.
Earthworms make continuous channels from the soil surface to the deeper layers, so that water can infiltrate quickly into the subsoil.
A taxonomic approach implies studying earthworm diversity based on the number and identity of different species species richnessregardless of their ecological role. To study the diversity of earthworms in different parts of the world, it is necessary for earthworm experts to train inexperienced earthworm taxonomists.
Hence, the effect of earthworms on greenhouse gas balance is still unclear and needs further understanding. Such earthworm species usually live in one region, in contrast to species that have been introduced by human activity. However, the importance of below-ground biodiversity, and earthworm biodiversity in particular, has not received much attention.
Reproductive strategies of earthworm population are the main indicators that help to determine the genetic diversity of these creatures. The role of earthworm for assessment of sustainability and as bioindicators. The importance of the Latin American meetings on oligochaete ecology and taxonomy.
Epigeic earthworms eat and live on rich litter surface layer and do not form burrows; they have small size body cm body length at maturityand bright color Jones, Suthar S Earthworm biodiversity in western arid and semiarid lands of India.
Currently, there are only few professional taxonomists in the world. However, many soils undergo degradation processes Lavelle et al. Indian Scenario A number of the biologists all over the world are studying the earthworm biodiversity Tsai et al. Morphological differences and effects of interspecific interactions.
A taxonomic approach implies studying earthworm diversity based on the number and identity of different species species richnessregardless of their ecological role.
Additionally, a broad range of distinct, restricted vegetation developments, including seasonally flooded grasslands, lowland floodplain swamps, and mangroves.
They maintain good soil health through the comminution of organic debris, enhance microbial activity, and contribute to the increase of nutrient availability in soil and mineral absorption by plants. Moreover, earthworm diversity studies have mostly focused on taxonomy and have not evaluated the association with ecosystem services.
The density and biomass of earthworms in the sugarcane areas were increased mainly by the organic matter inputs however the density and the biomass was still lower than that of the forest area.
Identification of earthworm species on the basis of morphology is difficult the reason being the lack of the stable and easily scorable diagnostic morphometric characters Pop et al. Earthworm life is also affected by predators, and especially birds Lee.
Earthworm Biodiversity in an Arid Region of Rajasthan, India Research Paper The biodiversity of earthworms is influenced by physical, chemical and biological properties of soil and climatic conditions of habitats. Earthworm’s biodiversity is directly affected by soil characteristics (Edwards and Lofty, ).
The earthworm species diversity, abundances and importance of soil organic pool in earthworm colonization were also assessed in some selected sites of northwestern arid and semiarid land of India.
2. Earthworm diversity and habitat preferences in arid of regions Rajasthan. The entire observations clearly indicate the richness of earthworm biodiversity in the arid region of Rajasthan. Hand out: Biodiversity Biological Diversity or Biodiversity - is the variety (diversity) of all life forms on earth, encompassing all plants, animals, microorganisms and the intricate ecosystems they form.
- the totality of ecosystems, species, and genes within the area. Levels of Biodiversity 1. Species Diversity (Different Life Forms) 2. mate the current status of earthworm biodiversity in western arid and semiarid lands of India.
A total of different locations (rural, urban, and sub-urban localities) arid land.
Earthworm fauna of this region showed a patchy distribution pattern and the majority of the species were.
Abstract. Efforts have been made in this study to estimate the current status of earthworm biodiversity in western arid and semiarid lands of India.Earthworm biodiversity in an arid region
