“…[4,14,16]). The concern is that exotic earthworms modify forest floor structure, soil characteristics and element cycling [3,15], which results in change in other soil biota and loss of native rare understory plant species [12,13,19].…”

“…There are studies about changes in abundance, presence or absence and biomass of earthworms observed under destructive activities or diverse management types in different regions (Hendrix and Bonlen 2002;Aubert et al 2003;Haynes et al 2003;Rombke et al 2005 ;Ammer et al 2006). Yet, previous studies have seldom been focused on both soil physiochemical properties and earthworms under destruction and short-or long -term conservation management conditions.…”

There has been observed widespread destruction of natural ecosystems around the world due to population growth, land use change and clear cutting which have affected soil properties. Different management strategies have been so far implemented to reduce this crisis in various regions of the world, such as e.g. short-term and long-term conservation management in the Zagros region. However, any management approach should be evaluated with appropriate measures to determine how managed areas respond. The main objective of the present study was to evaluate the potential of earthworms as an indicator for different forest management strategies and human disturbances in Zagros oak (Quercus persica Jaub. and Spach) forest. The sites selected included undisturbed one as the control (Un), the sites under five-year conservation management (FCM) and twenty-year conservation management (TCM) as well as the disturbed site (D). The results of principal component analysis (PCA) showed that different regions separated into the components: PC1 and PC2. Un and TCM sites gathered together and represented higher values of the factors such as pH, K available , OC, clay content, P available , CEC, overstory tree canopy, N tot , biomass and abundance of earthworms. The positive direction of the first axis reflected a gradient of EC, BD and P tot . According to the logistic model, NH 4 -N and EC played the most important role in earthworm presence and absence in Zagros forest ecosystem. Earthworm abundance and biomass could be a good indicator to evaluate different forest management strategies in the study area.

“…A recent study determined that earthworms alter carbon: nitrogen ratios, phosphorus fractions, and the distribution and function of fine roots and microbes (Doube and Brown 1998). While these effects may be beneficial to agricultural systems, they may be harmful to forest ecosystems over long periods of time if the forest is composed of plant species which have evolved or succeeded in the absence of earthworms (Bohlen et al 2002, Hendrix and.…”

A preliminary survey on earthworm species from north Karnataka region, Gulbarga district, Karnataka state, India, has been conducted from January 2012 to December 2013. Survey was conducted in three regions of Gulbarga district i.e. Afzalpur, Chittapur, and Sedam taluk. Six species of earthworms were identified belonging to four families namely lumbricidae, Octochaetidae, Megascolecidae and Eudrilidae. Eisenia fetida belonging to family lumbricidae, Dichogaster bolaui belong to family Octochaetidae, Polypheretima elongate, Perionyx sansibaricus and Perionyx excavates belong to family Megascolecidae and Eudrilus eugeniae belonging to family Eudrilidae. Among the species, Eudrilus eugeniae does not occur naturally and are produced from external sources for vermicomposting units.
