“…The actual sample size (obtained from eld sampling) acts as a reference sample to construct a sample size-based rarefaction and extrapolation curve(Budka et al 2019). In this study, Sample-based rarefaction approaches (three times the lowest reference samples with 1000 times randomization) have been considered for biodiversity estimation (rarefaction and extrapolation with Hill numbers)(Chao et al 2014;Mahata and Palita 2023). The analysis was carried out using package 'iNEXT' in R 3.4.3(Hsieh et al 2016).…”

To understand the impact of soil properties and land use systems on earthworm diversity in the biodiversity-rich Eastern Ghats Highlands of India, the present study was carried out in six land use systems i.e., moist deciduous forest, dry deciduous forest, fallow land, cropland, compost pit, and, sewage soil. The study area has been divided into 10 × 10 km 2 grids and 25% grids were randomly selected for sampling from May to December 2022. A total of 16 species of earthworms under 14 genera and 8 families were recorded in this study, out of which 15 species are new records for the region. The most taxonomically rich family was the Megascolecidae. The most abundant species are endogeic followed by epigeic and anecic. Based on Hill numbers, the highest values of Shannon index ( 1 D= 9.89) and Simpson diversity ( 2 D= 9.14) were found for the fallow land. Earthworm abundance showed a signi cant difference among six land use systems [F (5,84) = 3.25, p = 0.01]. Furthermore, earthworms showed a signi cant positive relationship with moisture (r = 0.22, p < 0.05), organic Carbon (r = 0.25, p < 0.05), available Nitrogen (r = 0.22, p < 0.05), and clay content (r = 0.43, p < 0.01), whereas negatively correlate with sand content (r = 0.32, p < 0.01) of soil. High species richness was observed in cropland due to the high moisture, pH, organic Carbon, Potassium, and, Phosphorus content of the soil.The presence of a high number of native species urges their conservation in this region through land management.

To understand the effects of local landscape factors on functional species composition and phenology of butter ies across multiple spatial scales, a study was carried out in a tropical dry forest of the northern highlands of the Eastern Ghats of India from November 2016 to October 2017. A total of 3343 individuals of butter ies were recorded, including 88 species of butter ies under 62 genera, 18 subfamilies, and 6 families in three different forest types (open, riparian, dense). Butter y species richness showed no signi cant deviations, but diversity patterns varied across transects. Beta diversity indicated differences in common species populations, likely due to uneven resource distribution in study site forests. The contribution of β transect to gamma diversity was greater than that of β elevation, except for specialists. Specialists were favoured by landscape attributes over forest type. Butter y abundance peaks in April for open and dense forests, and May for riparian forests. Results show variation in seasonal patterns across different forest types (F = 15.92, P < 0.001). Generalists and versatilists are more prevalent in April and February, while specialists are more abundant from October to November. Relative humidity, shrub density, and temperature were the major contributors (40.2%) for richness whereas relative humidity and shrub density contributed 26.3% for abundance. The relative humidity was predominant over temperature for species richness and is a major predictor for assemblages of generalist species. Resource utilization based on elevation plays an important role for habitat specialist species and highlights the importance of the spatial levels of elevation zones in conservation planning.
