Subject: Digital Morphometrics of Leaf Shape and its Application to Species Differentiation in some Species of Argyreia Lour. (Convolvulaceae)
Keywords: Morphometric analysis, Elliptical fourier descriptors, Leaf shape, PCA.
Abstract: Genus Argyreia belongs to the family Convolvulaceae and comprises flowering plants commonly known as silvervine or elephant creeper. These plants are native to tropical and subtropical regions, including parts of Africa, Asia, and Australia. Argyreia species are known for their large, attractive flowers and are often cultivated for ornamental purposes. Argyreia plants typically have simple and alternate, large, broad leaves. The leaves can vary in shape, often being ovate or cordate, and have prominent veins. Morphometric analysis of the leaves of eight (8) species of the genus Argyreia was carried out using Elliptic Fourier Analysis (EFA). Principal component analysis (PCA) was performed based on variance-covariance matrix. Resulting PCs are utilized to create a dendrogram via neighbour joining method using Euclidean distance. The dendrogram revealed three major groups among the presently analysed species of Argyreia. Group-I was comprised of four species i.e., A. pilosa, A. nervosa, A. boseana and A. sharadchandrajii. A. setosa, A. sericea and A. elliptica formed the second group. Due to different leaf shape A. cuneata has been placed in last group. Present study reveals the importance of morphometric analysis in species differentiation based on leaf shape and structure and can be used as additional identification tool when combined with other methods.

Subject: Fuelwood Burning : Utilization Trends for Forest Sustainability in the Cold Desert of Trans Indian Himalaya
Keywords: Trans-Himalayas, Fuel wood, Energy, Resource use index, Lahaul valley.
Abstract: In the Indian Himalayan region, heat energy consumption in terms of fuelwood is always given importance. This study has highlighted qualitative and quantitative consumption trends of fuelwood species utilized by people in the Lahaul Valley, a cold desert in the Trans-Indian Himalaya. For each plant species, the average quantum collection, probability of utilization, and Resource Use Index were assessed. The study revealed a diversity of 42 fuelwood species used by the tribal population. Among all the species, maximum Resource Use Index value and preference were recorded for Salix fragilis, followed by Juniperus polycarpos, and Pinus wallichiana. The study also highlighted the available stock of fuelwood species. In recent years, consumption pressure on fuelwood from the forests showed a declining trend, it could be the adoption of sustainable harvesting practices which will save energy by burning fuelwood. Of the total species, the higher dependence on native species (57.14%); near-endemic species (30.95%); and endemic species (2.38%) were recorded, this indicated the importance of these species for conservation. Hence, regular monitoring for extraction trends with changing attitudes of the people is required.

Keywords: Prosopis juliflora, Root suckers, Coppice shoots, Seedlings, Plantation, Invasive species.
Abstract: A safe and effective method is lacking for ecorestoration of forest area affected by Prosopis juliflora. Studies were conducted on root suckering and coppicing behaviour of this species. Lateral roots of the standing plants of P. juliflora were not found to have a natural tendency to produce root suckers. Young plants (<20 cm height) were found to be growing randomly at 0.3 to 6.1 plants/m2 plant density on the forest floor; these plants were of seed origin and were not connected with the roots of existing plants. Coppice shoots of P. juliflora arose from the junction between stem and root or slightly above this region. To undertake pilot trial, it was suggested that P. juliflora plants be removed by severing the tap root about 50 cm below the ground level and cutting off the lateral roots close to the plant without digging out the lateral roots. In order to physically suppress and outgrow the new P. juliflora, it was suggested to place, in the beginning of monsoon season, 1-2 tufts of Saccharum spontaneum, S. bengalense, Chrysopogon fulvus, Eulaliopsis binata or other hardy local grasses along with soil over the pit created by removal of P. juliflora. A mixture of native tree or shrub species should be planted at a density of 2,500 plants/ha to establish tree cover in the area to create a permanent tree canopy.

Keywords: Conservation, Genetic Diversity, Morphotypes, Rohida, Start codon targeted markers.
Abstract: Tecomella undulata commonly known as Rohida is an important timberyielding tree species of arid and semi-arid regions. It has become victim of overexploitation for its high quality timber and medicinal values because of which the species is categorized under threatened plants. Three different flower colour morphotypes viz., yellow, red and orange were recorded in the species. Flowers of Rohida are recognised as state flower of Rajasthan. To investigate the variation exists among these three different flower colour morphotypes of Rohida, Start Codon Targeted Polymorphism marker system was used. In the present study, 63 SCoT primers were tested, out of which 14 primers were found to be polymorphic generating 1045 scorable bands. Scorable bands per primer were obtained in the range of 20-118. The PIC and RP values of the primers ranged between 0.27-0.45 and 2.80-16.86. The estimated Jaccard similarity coefficient ranged from 0.038 to 0.579. The dendrogram constructed using Jaccard's coefficient resulted into two clusters, the first cluster including yellow morphotypes and the second cluster including red and orange flower colour morphotypes.

Subject: Forest Fire Risk Zone Mapping with Prediction of Forest Fire through Support Vector Machines (SVM) for Kothagudem, Telangana, India
Keywords: Forest fire, Machine learning model (MLM), Support vector machine (SVM), Forest fire risk index, Forest litter.
Abstract: Forest fire is major man-made and/or natural disaster in which the destruction is multifaceted. This risk required timely detection and need to be curbed before fire occurred as prevention. It is therefore essential to make fire risk zonation map so that the fire can be watched and controlled timely. For risk map in study area, factors that are assumed to be affecting forest fire are land use and land cover (LULC), distance from road, litter weight, aspect, elevation and slope using suitable, weight, rank and assigning an index which was further represented under low, moderate and high risk. The thematic layers of all these factors were constructed in Geographical Information System (GIS) and overlaid to delineate the fire risk zone map. The low-risk zones are in scrub-shrub, orchards, moist deciduous and agriculture while high and moderate risk of forest fire exist in dry-deciduous and degraded-dry deciduous forest area. The area under low risk is 35.94%, moderate risk is 47.18% and 16.88% under high risk. The forest fire vulnerable areas were also integrated with SVM classification model to predict the fire and non-fire points, with an accuracy of more than 80% for each zone and precision, recall and f1-score during testing phase for each zone gave good results. The predicted instances were mapped onto vulnerable areas and the analysis showed that SVM are able to classify fire points. The integration of remote sensing and machine learning models can help in delineating more accurate status of region and more precise information useful for monitoring and mitigation of forest fire.

Keywords: Biocontrol agent, earwig, frugivorous, molecular identification, powdery mildew
Abstract: Earwigs, with their frugivorous behaviour, consume fungi as part of their diet, but the specific fungal species and ecological implications vary. The present study specifically investigates the interaction between the black field earwig, Nala lividipes and powdery mildew fungus Golovinomyces cichoracearum that affects dahlias. The earwig was molecularly identified (accession number-OQ102948) as N. lividipes, with 99.70% similarity. The morphological examination of the fungi aligns with characteristics of powdery mildew attributed to G. cichoracearum, including upright and segmented conidiophores (195–239 × 11–16 µm) bearing three to four short chains of conidia in a basipetal arrangement. The conidia, which are hyaline, single celled, ovoid, and barrel-shaped (31–48 × 13–17 µm), exhibited no fibrosin bodies. The present study provides insight into the fungivorous association of N. lividipes with G. cichoracearum, highlighting its potential and feasibility as a future biocontrol agent.

Abstract: This study documents the morphological deformities in Brevitrygon imbricata (Bengal whipray) and Chiloscyllium arabicum (Arabian carpetshark) from the Indian coast. Notable deformities include a rostral irregularity in B. imbricata, resulting in a horn-like expansion, and a bifurcated second dorsal fin in C. arabicum. These findings highlight the need for further research into the causes of such deformities, which could be linked to various environmental stressors. The study emphasises the importance of monitoring these deformities for conservation and fisheries management

Abstract: Source apportionment of particulate matter samples using the chemical mass balance (CMB) approach is undertaken from a known set of information regarding chemical species present in the sources. The chemical species data pertaining to a particular source often would contain interfering chemical species originating from other sources due to the mixed state of its presence in the actual state. Such mixed source profiles, when used in the CMB analysis, result in collinearity and induce several errors in source apportionment analysis. To ensure the reliability of the source apportionment process, collinearity is to be eliminated by refining the source profiles used in the source apportionment process. The utility of synthetic datasets to refine the source profile in a source apportionment process is demonstrated for the particulate matter sampled from a non-urban region in the South Indian state of Kerala. To bring out cleaner source profiles, a large sample of receptor datasets that closely resemble the field data is generated using the artificial neural network module conditional tabular generative adversarial network(CTGAN) and principal component analysis/multi linear regression (PCA/MLR) approaches are further applied to isolate various combined sources, and the source profile information is refined using published information. The effectiveness of the refined source profile information in a CMB analysis is demonstrated using the field receptor data.

Subject: The magma-mixed granitoid system, Eastern Dharwar Craton, India: evidences from the mafic enclaves and syn-plutonic dykes from Madugulapalli
Keywords: Fractional crystallisation, granitoid system, heterogenies, magma mixing and mingling, subduction
Abstract: To understand the fundamental processes for the generation of granites, associated rock types and compositional diversity, we studied the Madugulapalli granitoids that constitute a part of the Eastern Dharwar Craton (EDC) of southern India. The Madugulapalli area consists of three rock types, including a host granitic rock (GN, syeno-monzogranite), mafic microgranular enclaves (MME) and syn-plutonic dykes (SPD). The MME and SPD are characterised by (a) spherical and ellipsoidal shapes with associated chilled margins, (b) the presence of megacrysts of K-feldspar and plagioclase and (c) the presence of acicular apatite, ocellar quartz and plagioclase with oscillatory zoning and resorption surfaces, all suggesting that they are globules of mafic magma derived from the mantle sources and SPD are injected into the crystal mush of the felsic host. Geochemical analyses suggest that MME and SPD are derived from the mixing of a partial melt from heterogeneous mantle and crustal source. The MME and SPD exhibit colinear compositions with the host GN, suggesting that they are the products generated by magma mixing in different proportions of injected mafic melts and the host granite. During various stages of crystallisation, granitic magma interacted with a smaller amount of mafic magma. Based on mixing calculations, a mass fraction of felsic magma (xA = 0.71) mingled with mafic magma to generate hybrid rocks in the Madugulapalli region. Field, petrographic and geochemical evidence suggests that they are generated in a subduction environment in which large-scale mantle and crustal-derived magmas are produced and mixed at the crustal emplacement level. Hence, the Madugulapalli rocks represent a magma-mixed granitoid system from the EDC

Subject: Preserving breeding habitats in socio-ecological systems: insights from the stenotopic toad species Duttaphrynus hololius
Keywords: Amphibians, common land, Eastern Ghats, endemic, ephemeral-pools, land conversion
Abstract: Amphibians that depend on both aquatic and terrestrial environments for their life cycle (lentic water breeders) utilise lentic water systems across diverse habitats like rivers, rocks, farms and forests. Successful breeding in these sites relies on natural water regimes, but anthropogenic alterations pose a significant threat. In the present study, we examined the impact of agricultural practices, small-scale granite mining and silt accumulation on the breeding cycle of the range–restricted and stenotopic Duttaphrynus hololius. We hypothesised that alterations to breeding pools, such as siltation and reduced water availability, would negatively impact the breeding success of this toad species. Our findings indicate that agriculture and grazing did not have a negative impact on breeding activities. Nevertheless, silt accumulation and granite mining were identified as major factors leading to unsuccessful breeding cycles. These results highlight the importance of conserving breeding habitats within socio-ecological landscapes for the persistence of this amphibian. Sustainable management practices are crucial to ensure the survival of D. hololius, particularly those that mitigate the negative impacts of silt accumulation and small-scale granite mining.
