Abstract: Eucalyptus is a versatile genus with a particular significance for paper pulp, and it is extensively cultivated in India's marginal lands. Eucalyptus camaldulensis and E. tereticornis are highly preferred due to its optimal pulp yield, excellent fibre quality and good abiotic stress tolerance properties. Marker-assisted selections have played a major role in eucalyptus breeding programs. The use of genotyping-by-sequencing (GBS) approach for a largescale single nucleotide polymorphism (SNP) discovery and genotyping of an inter-specific mapping population, Eucalyptus tereticornis × E. camaldulensis are reported in this study. Reduced representation libraries of 81 F1 progeny were sequenced and number of SNPs considered for linkage analysis was 96,377 single nucleotide substitutions, most of which (54.03%) represented transition events. Totally, 1999 and 4206 SNP markers were mapped to female (Eucalyptus tereticornis) and male (Eucalyptus camaldulensis) map, respectively. Consensus map consisting of 4844 markers were placed on a linkage map, which spanned 1367.6 cM and had an average of one marker every 0.29 cM corresponding to a physical distance of about 0.66 Mb. The map was utilized to identify six quantitative trait loci (QTLs) associated with adventitious rooting traits of stem cuttings accounting for phenotypic variations ranging from 7.18% to 9.17%. Analysis of the genomic sequence corresponding to six QTLs led to the identification of 201 putative candidate genes and 4 key genes were related to adventitious rooting specific expression. The integrated strategy utilizing the identified QTLs along with the available genome could serve as a platform for candidate gene identification for molecular breeding of eucalypts.

Keywords: Tree Species, Mass Multiplication, Mini Clonal Technology.
Abstract: The growing importance on promotion of plantation and agroforestry in India demands production of quality planting materials to satisfy the demands of tree growing farmers and wood based industries. The National Forest and Agroforestry policies also prioritized ensuring quality seedling production for successful establishment of forestry and agroforestry plantations. As of now, most plantation activities in the country are carried out through seed based seedling production barring few exceptions which exhibited wide variations in growth, yield, productivity and adoptability. Under such circumstances, The Forest College and Research Institute (TNAU) has developed species specific mini clonal technology for wide range of pulpwood, plywood and timber species viz., Eucalyptus, Casuarina, Melia, Teak, African Mahagony, Toon and Kadam. This innovative mass multiplication technology exhibits greater potential of adoption across regions towards mass multiplication of wide range of species and to ensure quality seedling production as envisaged in National Agroforestry policy. The rapid multiplication coupled with increased rooting efficiency in a short duration and elimination of epigenetic variation attracts this technology as a most promising in forestry and agroforestry plantation development program.

Abstract: Red sanders are one of the highly valued tree species in the world, native to south parts of Eastern Ghats (Andhra Pradesh and Tamil Nadu). As the success of any tree improvement depends upon the amount of variations found in heritable traits of populations and is basis for future genetic improvement, the present study was carried out to assess the variations in growth traits, bark, sap- and heartwood of different populations of red sanders in Karnataka. Hullikere (43 years), K.Settihalli (47 years), Jharakabande (32 years), Nallal (42 years), Yeshwanpur -A (42 years) and Yeshwanpur-B (42 years) in Karnataka. Significant variability found in growth traits viz., girth, straightness, tree height and sap- and heartwood content of the Red sanders. Time of heartwood formation varies within and between trees as well as between the populations. Both content and colour of heartwood vary even in the trees of same girth in a stand. No heartwood was found in trees which had girth <37, <41, <44, <46 and <48cm at breast height in Jharakabande, Hullikere and Yeshwanpur-B, Yeshwanpur A, Nallal and K.Settihalli plantations, respectively. The heartwood formation was not depicted any trend with tree size and age of trees in the Redsanders populations.

Keywords: Empirical Formula, Girth at Breast Height (GBH), Timber, Volume.
Abstract: The standing tree volume is a measurement of the amount of merchantable volume and available growing stock in forests and trees outside forest areas. The precise estimation of the tree log volume plays an important role in sustainable forest management and also in trees outside forest areas. Several scientists have derived various tree log volume calculation formulae, which are used in estimating standing tree volume. The Gujarat State has very rich forest biodiversity. The forest department has done very good work in conserving existing forests and achieved outstanding success in planting and raising trees outside forest areas through a successful social forestry program in the State. The efforts through public participation have resulted in to increase in forest cover of the State. The present investigation was carried out at Gujarat Forest Research & Training Institute, Gandhinagar campus to develop an empirical formula for estimating standing timber availability from different selective tree species of Gujarat. The attempt has been made to measure Girth at Breast Height (GBH), Clean Bole Height (CBH) of selected tree species, and round log volume was calculated using a quarter girth formula assuming it to be a cylinder. Considering principal factors behind tree growth that 1) the height is a function of girth, 2) young, aged tree grows at a double rate that in middle age and 3) mature tree hardly puts any height or girth, a general growth formula has been derived. The general growth formula was validated for different species based on actual measurement of effective height. Finally, the empirical formulas were developed based on the Regression of derived formula V = A G2 10-5ebG for different tree species.

Abstract: Eight clones of Casuarina (four of Casuarina junghuhniana and four of interspecific hybrids of Casuarina equisetifolia × C. junghuhniana) were subjected to saline water irrigation with different concentrations of NaCl viz., 0, 40, 80 and ;120 mM. After twelve months of study period, plant height, collar diameter, plant fresh weight, root length, proline, total soluble sugars reducing sugars, relative leaf water content, and Na+/K+ ratio showed high and positive correlation with plant dry weight. Path analysis revealed that collar diameter, root length, reducing sugars and relative leaf water content had the highest direct effect on plant dry weight and can be collectively used as selection criteria for improvement of Casuarina for increasing biomass.

Abstract: Acacia auriculiformis A.Cunn.ex Benth is one of the fast-growing exotic timber species. Thorough understanding of mating systems is influencing towards an efficient tree breeding design. Thus, plant mating systems play an important role in shaping the genetic composition of progeny generations. Institute of Forest Genetics & Tree Breeding (IFGTB), Coimbatore has established Seedling Seed Orchards of Acacia auriculiformis in Southern States (Tamil Nadu and Kerala) of India. Two successive generations of this species were studied for its mating system based on microsatellite markers. Five microsatellite loci were studied among the three hundred half-sib progenies of both first and second orchard populations. Out-crossing rate was estimated The range of the maternal, paternal genotypes among the individuals in the family was also studied in the orchards. The present study indicated high out-crossing rate in first- and second-generation orchards population and it reflects that this species is highly out-crossed. The gene frequency estimates of the first- and second-generation progenies were studied that there was no significant variation in the pollen and ovule gene frequency estimate in both generations. The range of the maternal genotypes was 1 to 2 among the individuals in the family. The high out-crossing rate (tm=0.98; SE= 0.05; tm=1.0; SE=0.02) in the orchards indicated that the species is predominantly out-crossed.

Keywords: Rhododendron arboreum, Cotyledonary Leaves, Charcoal, Genomic DNA.
Abstract: The extraction of high-quality DNA from different plant source is a limiting factor in genetic diversity studies of any tree species. DNA extraction is the preliminary and essential step for almost all molecular marker based genetic studies. High-quality DNA extraction from cotyledonary and mature leaves of Rhododendron arboreum is extremely difficult due to the presence of high concentration of polyphenols and polysaccharides. These contaminants, if present in the extracted DNA severely affects the PCR amplification. Therefore, a method of DNA extraction from the cotyledonary and mature leaves has been developed. Solubility of polysaccharides was minimised with high salt concentrations (3M) and polyphenols removed by adding, Polyvinylpyrrolidone (2%) and activated charcoal (1%) in the DNA extraction buffer. Additionally, RNase-H was used to remove RNA contamination. The extracted DNA was quantified using bio-spectrophotometer. DNA was obtained with concentration ranging from 2.30 to 4.70μg with the absorbance ratio of 1.80 to 1.88, per milligram of cotyledonary leaves and 4.25 to 7.70μg with the absorbance ratio of 1.80 to 1.88, per milligram of mature leaves. Further, quality of extracted genomic DNA was assessed by random amplified fragment length polymorphism (RAnd simplePD) a sequence repeat (SSR) markers.

Keywords: Anisopterans, Zygopterans, Stream, Lakes, Coimbatore.
Abstract: A study was conducted to assess the diversity of odonata in the rural and urban wetlands of Coimbatore, Tamil Nadu, India from August 2018 to January 2019. A total of 4 wetlands from rural and urban were surveyed with a total of 8 families of 32 genera and 45 species were recorded. Among them, 8 families of 21 genera and 26 species from Kallar a tributary stream and 4 families of 20 genera and 25 species from Ukkulam lake of rural whereas 4 families of 15 genera and 18 species from Singanallur lake and 3 families of 9 genera and 10 species from Kurichi lake of urban. Among the anisopterans, Brachythemis contaminata (Fabricius, 1793) was abundant in the urban lakes, Pantala flavescens (Fabricius, 1798) in the rural stream and Diplacodes trivialis (Rambur, 1842) in the rural lake whereas in the zygopterans, Neurobasis chinensis (Linnaeus, 1758) dominated in the rural stream, and Ischnura aurora (Brauer, 1865) dominated over the lakes.

Subject: Ecological Studies on the Population Composition, Group Size and Diurnal Activity Pattern of Blackbuck, Antilope cervicapra (Linnaeus, 1758) (Mammalia: Cetartiodactyla: Bovidae) in Western Haryana, India
Keywords: Activity Pattern, Blackbuck, Group Size, Population Composition, Threats.
Abstract: Population composition, group size and diurnal activity patterns of Blackbuck, Antilope cervicapra were monitored in significant population at Lalpur Jheel, Dobhi Village of district Hisar (Haryana) and the relevant data was collected following scan sampling method, during March, 2017 to February, 2019. Population structure data revealed that the population was dominated by adult female. In comparison to adult individuals, greater number of sub-adults and young were recorded. The overall mean group size ± S.E. recorded from March, 2017 to February, 2019 was 13.19±1.29 in 130 sightings, comprising of 1716 individuals sighting. Diurnal activity data reflected that standing was the highest annual mean per cent activity recorded during both the study years. Variation in the highest mean per cent activity between same seasons of first (March, 2017 to February, 2018) and second year (March, 2018 to February, 2019) were noticed. Habitat fragmentation caused by construction of road, disturbance caused by plying of vehicles, increased grazing pressure caused by construction of gaushala were the major factors responsible for changes in the diurnal activity pattern between first and second year.

Subject: Forage Plants of Gaur (Bos gaurus H. Smith, 1827) in Tropical Forest of Southern India
Keywords: Gaur, Bos gaurus, Diet Composition, Forage Plant Species, Mudumalai Tiger Reserve.
Abstract: Forage plant species of Gaur (Bos gaurus) were studied by direct observation using focal sampling (90 hours) about 30 hours of sampling in three major habitats (Tropical dry deciduous forest, Moist deciduous forest and Thorn forest) in Mudumalai Tiger Reserve, Southern India from Jan-2003 to Aug-2004, also studied by feeding trail plots (924 1m2 plots and 495 5m2 plots) sampled in all the habitats. Gaur was observed to forage on 155 species of plants belonging to 38 families under 23 orders. Among different plant, physiognomic types trees and shrubs constituted a greater proportion by orders Rosales and Malvales. Herbs constituted 32% of the overall plant selected and consisted of 49 species in 17 orders and dominated by Asterales. The plant families such as Poaceae, Fabaceae, Asteraceae and Malvaceae collectively formed the major food species. Among the different species 29 grass, 9 herb species, 9 shrubs and 11 tree species were having more than one preference value. Gaur prefers to forage on Cenchrus purpureus, Axonopus compressus, Sprobolus diander, Themeda triandra, Oplismenus undulatifolius among grasses and Asystasia chelonoides and Sida cordifolia among herbs. The forage plant species of gaur was compared and discussed with other habitats of gaur distributional range.
