Abstract The Madras hedgehog (Paraechinus nudiventris) is a less-known insectivorous mammal, endemic to southern India, and known from the states of Tamil Nadu, Kerala, Karnataka, Andhra Pradesh and Telangana. The nocturnal habit, small body size and elusive nature of P. nudiventris have resulted in limited studies on its habitat selection and ecology. The confirmed locations of P. nudiventris from our field surveys and existing sight records were pooled. These geocoordinates were then used as the “occurrence location” to predict the potential distribution range of P. nudiventris in southern India based on a set of climatic and terrain variables using the MaxEnt algorithm. The predicted model shows the suitable ecological conditions in the districts of Erode, Tirunelveli, Tuticorin, Coimbatore and Tiruppur in Tamil Nadu, making them highly probable sites for its presence. Most of the predicted suitable range and high potential range fall in the non-protected semi-dry zones characterized by low annual rainfall with sparse savanna vegetation, lowland [0–750 m above sea level (asl)] and the rural areas of southern Tamil Nadu. Our findings establish the potential distribution range of this species in parts of Karnataka, Andhra Pradesh, Kerala and most of Tamil Nadu.

Eucalyptus Camaldulensis Dehnh

Abstract A total of 188 open-pollinated families of Eucalyptus camaldulensis Dehnh. from 18 Australian natural provenances and 15 selected Indian families of the “Mysore Gum” land race were evaluated in three provenance- family trials at contrasting sites in southern India. At two years of age, the fastest growth was recorded at the driest site in Tamil Nadu, where E. camaldulensis provenances from Queensland were superior to those from Northern Territory and Western Australia, and the Indian land race. Provenance differences were less pronounced at the two higher-rainfall sites in Andhra Pradesh and Kerala. Interaction of provenance performance with site was significant. Within- provenance individual-tree heritabilities for height and diameter at breast height (dbh) were low at the three individual sites, ranging from 0.08 ± 0.05 to 0.19 ± 0.05 for height and 0.10 ± 0.05 to 0.19 ± 0.04 for dbh. Across-site heritabilities, 0.07 ± 0.02 for both height and dbh, were lower than those at individual sites. Phenotypically superior trees were selected from these trials and seven other plantings of E. camaldulensis and Eucalyptus tereticornis Smith in southern India and cloned from basal coppice. A total of 78 E. camaldulensis and 27 E. tereticornis selections, together with thirteen commercially planted Eucalyptus clones and five superior natural provenance seedlots, were tested in clonal trials at three sites in southern India, the different individual treatments being tested at from one to three sites. Three years after planting, most clones selected from E. camaldulensis trials and the commercial Eucalyptus clones were superior in volume production to E. tereticornis clones and seedling controls at a dry site in Tamil Nadu. A smaller number of clones, particularly those of E. camaldulensis, were also superior to seedling controls at an intermediate-rainfall site in Andhra Pradesh. At a third high-rainfall site in Kerala, seedling controls were superior to all but four of 46 clones tested. Significant clone-by-site interaction was observed for growth traits. At the dry site in Tamil Nadu, clones varied widely in their wood basic density from 450 to 700 kg m-3, and there was no significant correlation of clonal values for growth and wood density. The results confirm that clones are best selected and tested in environments similar to those where they will be deployed.

The study was conducted to evolve Gloriosa superba for yield characters and alkalodi content for selecting elite genotypes for comercial exploitatio n. The genotypes were sowm in Variyankaval village, Udayarpalayam taluk of Ariyalur district, Tamil Nadu. The highest mean value for fresh and dry seed yield was observed in Chittor local. The genotype Mulanur local has recorded the highest mean value for number of pods per plant and number of seeds per pod and Arupukotai local excelled the general mean for the traits seeds per pod, fresh and dry seed yield and also for tuber characters. An investigation was carried out to quantify the colchicine (alkaloid) present in tubers by High Performance Liquid Chromatography (HPLC) method. The genotypes collected from Arupukotai recorded the highest colchicine content (0.760 mg/g) followed by Chittoor (0.578 mg/g) and Mulanur (0.496 mg/g) and there by these three genotypes were utilized for further crop improvement.

Extended Range

Eastern Ghats are discontinuous hill ranges passing through Orissa, Andhra Pradesh and Tamil Nadu located between 11⁰30' & 22⁰N latitude and 76⁰50' & 86⁰30'E longitude. Bryophyte flora of this region is still very less explored. During a recent field exploration to Eastern Ghats region of Tamil Nadu three moss taxa viz. Solmsiella biseriata (Austin) Steere, Aulacopilum glaucam Wilson and Groutiella tomentosa (Hornsch) Wijk & Marg. have been identified as new additions to moss flora of Eastern Ghats. The present study provides the information regarding extended range of distribution of these taxa in India and a compensable account of morpho-taxonomical details with earlier described taxa from other bryogeographical zones.

Economic Well Being

The outreach of micro-finance programme is considered to be a means enhance the economic well-being among the member means to enhance households through poverty alleviation. A wide cross-country variation in the outreach of micro-finance programme to the poor households is observed in the world. Despite the significant growth of micro-finance institutions and its active borrowers, the penetration of micro-finance lending services to the poor households in India is observed to be limited. In addition, there is a wide inter-state disparity in the achievement of micro-finance outreach in India especially among the poor households. A composite index has been constructed using the penetration, availability and usage indicators of micro-finance outreach to examine the interstate variations in the level of its achievement. Subsequently, attempt has been made to analyse the role of micro-finance in alleviating poverty across the states of India. The result shows that out of 27 states and Union Territories, only in seven states (Kerala, Andhra Pradesh, Tamil Nadu, Goa, Himachal Pradesh, Tripura, and Karnataka) outreach of micro-finance programme has made a significant impact on the reduction of poverty.

Leafhopper genera and species of the tribe Mukariini from the Indian subcontinent are revised. Nine genera and 22 species including two new genera, one new subgenus and 12 new species are dealt with. The new taxa described are Aalinga gen. nov. with its type species Aalinga brunoflava sp. nov. (India: Andaman Islands), Buloria indica sp. nov. (India: Karnataka). Buloria zeylanica sp. nov. (Sri Lanka), Flatfronta bella sp. nov. (India: Karnataka; Bangladesh), Mohunia bifurcata sp. nov. (Myanmar), Mukaria omani sp. nov. (India: Gujarat, Karnataka, Madhya Pradesh), Mukaria vakra sp. nov. (India: Karnataka), Mukariella gen. nov. with its type species Mukariella daii sp. nov. (India: Manipur), Myittana (Benglebra) cornuta sp. nov. (India: Karnataka), Myittana (Myittana) distincta sp. nov. (India: Karnataka), Myittana (Savasa) subgen. nov. with its type species Myittana (Savasa) constricta sp. nov. (India: Andhra Pradesh, Gujarat, Haryana, Himachal Pradesh, Karnataka, Madhya Pradesh, Punjab, Tamil Nadu, Uttarakhand) and Scaphotettix arcuatus sp. nov. (India: West Bengal, Meghalaya, Mizoram). Genera Buloria Distant (new placement), Crispina Distant (new placement) and Myittana Distant (new placement) are placed in the tribe Mukariini. Genus Mohunia is redefined based on the study of its type species. Benglebra Mahmood & Ahmed 1969 is synonymised with Myittana Distant 1908 and considered as its subgenus. Myittana (Benglebra) alami (Mahmood & Ahmed) comb. nov., Myittana (Savasa) bipunctata (Mahmood & Ahmed) comb. nov.. Myittana (Benglebra) introspina (Chen & Yang 2007) comb. nov. and Mukariella bambusana (Li & Chen) comb. nov. are proposed; the first two species were earlier placed in the genus Benglebra, the third species in the genus Mohunia and the fourth in the genus Mukaria. Genera Flatfronta Chen & Li and Myittana are new records for India and Scaphotettix striata Dai & Zhang is a new record for the Indian subcontinent and Sri Lanka. All taxa dealt with are described and illustrated and keys for genera and their species are also given.
