Subject: Seasonal Diversity Of The Finfish Community In A Tropical Estuary, South-East Coast Of India, Tamil Nadu
Keywords: Estuarine ecosystem, diversity indices, physicochemical parameters, management.
Abstract: Efficacious management and health assessment of estuarine ecosystems is augmented when comprehensive data on biodiversity is accessible. Correlations between species diversity and physicochemical factors are core information for directing management tactics and conservation planning. Present study was conducted from January to December 2023 to evaluate the measures of finfish diversity in the Muthupet estuary as a component of the Ramsar site, Point Calimere wetland complex. The diversity indices were unraveled monthly and seasonally (post-monsoon, summer, pre-monsoon, and monsoon). The ranges of Shannon-Wiener diversity (H’), Margalef’s richness (d), Pielou’s evenness (J’), Simpson diversity (1- λ), Taxonomic diversity (∆),Taxonomic distinctness (∆*), Average taxonomic distinctness (∆+) and Total phylogenetic diversity (sPhi+) were 2.467 to 3.858, 3.945 to 10.935, 0.935 to 0.977, 0.934 to 0.984, 69.290 to 76.551, 74.158 to 77.787, 74.066 to 78.519 and 800 to 3060 respectively for monthly gillnet finfish samples and 3.34 to 4.26, 6.82 to 15.43, 0.956 to 0.963, 0.970 to 0.987, 73.798 to 76.114, 76.045 to 77.092, 76.129 to 78.014, and 1800 to 4420 respectively for seasonal data. The Bray-Curtis similarity was zenithal between the pre-monsoon and summer, at 64.93%. The monthly and seasonal fluctuations in diversity were analysed using nonmetric multidimensional scaling (NMDS), which showed 40% resemblance across the monthly samples and indicating that the monsoon unveiled the highest species richness. The temporal oscillations in diversity were influenced by various environmental drivers, such as rainfall, tidal fluctuations, freshwater influx and seasons. Effective management inputs, such as ecological monitoring and assessment, community participation and governance, policy and regulatory frameworks, capacity building and education, economic incentives, and infrastructure and technology, are essential for sustaining resources that enhance the livelihoods of local people in this estuary.

Subject: Distribuion and habitat use by shola birds of the Nilgiris
Keywords: Endemic birds, forest specialists, habitat use, land-use , land-cover, shola
Abstract: Economic development and food security have led to significant land-use changes worldwide, posing challenges for conserving biodiversity and natural systems. Protected areas offer a safe refuge for wildlife, but their coverage is often inadequate. In the Western Ghats biodiversity hotspot, habitat loss and fragmentation threaten endemic and endangered bird species. The most at risk are restricted-range species such as shola specialists of the high elevations. This study assessed bird diversity and abundance in the montane Nilgiris landscape by conducting point counts across a complex habitat matrix, emphasizing the shola bird community. Field work was carried out from March 2023 to June 2023.Natural forests and urban parks showed high species richness. But when obligate commensals like crows and pigeons were excluded, bird abundance decreased significantly in settlements and parks. Urban parks appeared to play a role in providing refuge and improving connectivity for birds in the landscape. Shila birds were mostly seen in natural forests and timber plantations, with the Nilgiri laughingthrush being partial to natural forests. Our mapping , exercise also showed that the potential habitat available to high-altitude shola birds beyond Mukurthi National Park in the montane Nilgiris is around 500 sq.km. The role of different land cover types and landscape contexts in shaping avian communities in human-dominated landscapes is emphasized .Protecting natural habitats and restoring other potential habitats can benefit endangered species like the Nilgiri laughingthrush and Nilgiri sholakili. The need for sustainable land-use practices in conservation efforts to secure the future of montane shola birds in the Nilgiris is highlighted.

Subject: Spatial patterns of sea urchin diversity and their relationship to ecosystem health in the gulf of Mannar
Keywords: Sea urchin diversity, Gulf of Mannar, species richness, benthic habitat, conservation
Abstract: Th Gulf of mannar, a marine biodiversity hotspot, is home to diverse ecosystems, including significant sea urchin populations.A survey conducted from July 2023 to October 2024 across 13 islands in the Gulf of Mannar, a marine biodiversity hotspot, identified six a sea urchin species. Hare island exhibited the highest species richness, hosting five species (Salmacis virgulata, Temnopleursu toreumaticus, Gymnechinus sp., Brissopsis alta and Lovenia elongata) with a total of 110 individuals, alongside diverse macroalgae and coral. This island displayed high biodiversity (Simpson's D'=0.6774, Shannon-Wiener H'=1.2340) and even species distribution (evenness Index E=0.7667).Notably, Gymechinus sp. was recorded for the first time in the Hare Island region. The Vhaan Island showed moderate diversity with three species (S.virgulata, S.bicolor, and T.toruematicus) and 36 individuals. The Kasuwari Island had the lowest diversity, with only two species (S.virgulata and S.bicolor) and nine individuals, resulting in lower-diversity indices (D'=0.3457, H'=0.5297) and uneven distribution (E=0.7642) due to the dominance of S.virgulata. The sea urchin distribution correlated with specific macroalgae and coral species, emphasizing the importance of healthy benthic habitat. This study highlights the need for conservation measures, including bycatch reduction, predator monitoring, and long-term population tracking, to protect sea urchin populations and overall ecosystems health in the Gulf of Mannar

Subject: Comprehensive analysis of Road kills in Tamil Nadu Highway network:identifying hotspots and suggesting mitigation measures
Keywords: Animal-vehicle collision, conservation strategies, wildlife mortaity, protected areas, road network
Abstract: The expansion of road networks profoundly influences the environment and biodiversity. Roads often led to animal-vehicle collisions and act as a barrier to animal movement, thus increasing animal mortality. This study analysed roadkill hotspots within Tamil Nadu's extensive road network, spanning 1,99,040 km. The research aimed to identify spatial and temporal trends, compile species-specific roadkill data, identify vulnerable areas, and suggest appropriate mitigation strategies. Tamil Nadu is a biodiversity hotspot with 26,451 sq.km of forest cover. Roadkill data were collected between 2018 and 2023 from 45 forest divisions through questionnaire surveys, online sources (e.g., iNaturalist, Indian Biodiversity Portal etc.) and incidental sampling was used during road surveys. Hotspots were identified using QGIS, and road characteristics were evaluated at each hotspot. The collected data were evaluated using spatial, temporal and division-wise hotspots. The study documented 1,552 roadkill incidents involving 68 species across mammals (69%), birds (27%) and reptiles (4%). Spotted deer (47%) and Pefowl (27%) were the most frequently encountered species, followed by Bonnet macaque (5%) and Wild pig (5%).Spatially, the Tiruchirapalli Forest Division had the highest incidents, with agricultural land being the primary hotspot. Temporal analysis revealed that the roadkill incident increased annually, peaking in 2022.Dry seasons witnessed higher mammal roadkill, while avian and reptile collisiions peaked in west season. In hotspot analysis, National and State highways were the most involved in animal road accidents. Tiruchirappalli, Perambalur, Villupuram, Tirunelveli and Dindugal forest divisions are the most roadkill hotspots.

Subject: Conservation of tropical dry evergreen forest (TDEF) within Tamil Nadu
Keywords: Tropical dry evergreen forest, sacred groves, ecological status, biodiversity conservation, rapid assessment survey, conservation strategies.
Abstract: Sacred groves, remnants of the Tropical Dry Evergreen Forests (TDEF), are ecologically and culturally significant, serving as biodiversity reservoirs and spiritual sites. This study was conducted from 2021 to 2022.We examined 58 sacred groves through an integrated methodology, including field surveys, GIS mapping and historical satellite imagery analysis, to assess their size, canopy cover, species diversity and ecological health. The findings revealed a steady decline in vegetative cover, with 58 % of groves experiencing canopy loss over the past two decades. Key drivers of degradation include temple expansion, deforestation, understory clearing and waste accumulation. Despite these challenges the groves continue to support rare and vulnerable plant species highlighting their role as biodiversity banks. The study emphasizes the urgent need for conservation efforts, awareness initiatives and sustainable management strategies to protect these fragile ecosystems and preserve their ecological and cultural value.

Subject: Study on the impact of ocean acidification on the aragonite saturation state (ῺAR) in the coral reef ecosystem of the gulf of Mannar and Palk bay and mapping blue carbon hotspots for harnessing ecosystem-based services as well s climate change mitigation
Keywords: Aragonite saturation state, ocean acidification, coral reef ecosystem, gulf of Mannar, Palk Bay
Abstract: Ocean acidification (OA), driven by atmospheric Carbon dioxide (CO2) absorption, poses significant risks to coral reef ecosystems and calcifying organisms worldwide. OA reduces the availability of aragonite, which is essential for coral calcification and ultimately weakens coral structures and reduces reef growth. The Gulf of Mannar (GoM) and Palk Bay (PB), located on the southeast coast of India, ae vital marine regions providing critical ecosystem services, including biodiversity support, carbon sequestration, and fisheries production. Between January 2023 and September 2024, we conducted a pilot study to assess the aragonite saturation state (ῺAR) across 24 stations in these coastal waters, alongside measurements of pH, temperature, salinity, nutrients, and carbonate parameters following the Global Ocean Acidification Observing Network (GOA-ON) protocol. The results revealed PB exhibited higher pH (mean ± SD of pH 8.08 ± 0.02), with ῺAR values ranging from 2.64 in GoM-indicative of marginal calcification conditions to 6.71 in PB, signifying optimal conditions for calcifiers. The findings highlighted lower ῺAR values in GoM, suggesting an alarming trend towards marginal calcification conditions, which could compromise coral reef growth and resilience. This aligns with observed global trends where increased anthropogenic CO2 emissions exacerbate acidification in nearshore environments. This study underscores the importance of regular monitoring of OA parameters in these regions and hi9ghlights the need form cooumnity-ased conservation strategies to protect these critical ecosystems and their associated services.

Subject: Anaysis on genetic diversity of threatened medicinal epiphyte pleione maculata from different geographical habitats using RAPD and ISSR marker
Keywords: Pleione maculata, RAPD, ISSR, Genetic diversity
Abstract: Pleione maculata is a threatened medicinal epiphyte, as pseudobulbs are used to cure headaches, stomachaches and liver diseases. There are currently no reports on genetic diversity studies of P.maculata utilizing a molecular marker system that is relevant for conservation and breeding. Therefore, patterns of genetic variability and intrspecific similarities across P.maculata from the three different geographical distributions were assessed in this study using Random Amplified Polymorphic DNA (RAPD) and Inter Simple Sequence Repeat (ISSR) markers. From the 16 RAPD and 2 ISSR markers evaluated, a total of 96 distinct and reproducible DNA amplicons were generated. The morphological dissimilarity matrix was calculated using the Mantel test and Nei's genetic diversity coefficient. The highest computed PIC value for RAPD was 0.44, whereas the highest PIC values for ISSR were 0.48. The two sets of molecular markers used were highly correlated, with a correlation Mantel statistic (r) of 0.79, indicating high marker efficiency in population genetic studies. The results of this study will provide a basis for understanding genetic link, genetic variation and strategies for establishing a germplasm collection for the species conservation, Managment, breeding, and hybrid production within the P.maculata population.

Subject: First report of Sap sucking insect pests on Dalbergia latifolia (Roxb).from nonnatural growing region of India
Keywords: Dalbergia latifolia, Rosewood, Defoliators, New records, Sap suckers
Abstract: Insect pests infesting Dalbergia latifolia were documented within plantations located in non-native regions of India. Although D.latifolia has been introduced to various regions in India, there is lack of comprehensive research on insect pest record. To evaluate the prevalence of insect pests in newly established growth areas of D.latifolia, systematic observations were conducted in Uttarakhand. Many insect pests infesting D.latifolia were recorded so far, through infestation of four insect pests, namely Ricania speculum, Leptocorisa acuta, Leptocentrus taurus, and Dorsicha stebbingi on Dalbergia latifolia were exhibited for the first time. The research also uncovered the nature of the damage inflicted by these insect pests and their seasonal occurrence patterns. This periodic data on insect pest infestations can prove invaluable for the sustainable management of insect pests and the preservation of D.latifolia in the region.

Subject: Assessment of threatened tree species of the Nilgiri Biosphere Reserve (NBR), Southern Western Ghats, India
Keywords: Conservation status, Economic importance, Protected areas, Environmental sustainability
Abstract: The Western Ghats is the world's second-most significant refuge for species at risk. The Nilgiri Biospehere Reserve, a part of the southern Western Ghats region is one of the richest biogeographic regions in the Indian subcontinent. The present study documented a total of 68 taxa belonging to 50 genera and 35 families. Certain threatened factors, like overexploitation of natural resources and other anthropogenic activities, adversely affect the existing ecosystem and lead to the rarity of many species in the future. Therefore, the study suggests that there is need to protect ecologically sensitive forest patches due to the occurrence of many endemic and threatened species in this region.
