Odonata Diversity in Thadiyankudisai, Palni Hills of Western Ghats, Tamil Nadu

Abstract A total of 419 individuals under 5 families, 8 genera and 10 species of Odonata were recorded in the present study. Among them family Libellulidae had 6 species followed by Chlorocyphidae (2 species), and Coenagrionidae and Euphaeidae had1 species. The dominance order of Odonata was Pantala flavescens (44.40%) > Diplacodes trivialis (22.70%) > Orthetrum chrysis (7.40%) while rest of the fauna ranged from (1.40 to 6.90%). Pantala flavescens was maximum during NEM (50.0%) followed by summer and winter (43.8% each) and minimum during SWM (38.5%). Margalef Index of Species Richness was highest (2.00) during winter. Simpson Index of Diversity was highest (0.75) during SWM while Shannon-Wiener Index of Dominance was highest (1.75) during summer. The species were evenly distributed during summer with Pielou’s Evenness Index value of 0.76. The community change was 80.00 per cent change during January, 2018 and had a steep fall in February and April, 2018 and reached a peak of 66.67 per cent during March and November, 2018.

This study used plate count method to analyze the composition of the Spore-forming bacteria community in the soil in swamping wetland, alkaline land, and desert belt, all of which grow in the upstream, midstream and downstream of swamping wetland of Wuliangsuhai. In this process, the Shannon-Wiener index, Simpson index were used to analyze the index of diversity (H), the index of evenness (J), the index of richness (R) and the index of dominance (D) of the Spore-forming bacteria community. The results showed that: the diversity index of in soil of the swamping wetland and desert belt was the highest in the midstream, second in the upstream, and lowest in the downstream; that in soil of the alkaline land was the highest in the midstream, second in the downstream and lowest in the upstream, and showed significant differences between in the midstream and downstream and in upstream; that in soil of the desert belt showed significant differences between in the upstream and downstream and in midstream; in the same area, in the desert belt soil of Spore-forming bacteria more than swamping wetland and alkaline land.

The study of butterfly in the in Air Dingin Landfills needs to be carried out to find out what types of butterflies are in this area and how their diversity is, given the increasing area of Landfills that will change the surrounding environment into a place of rubbish heap. The study was conducted by implementing survey method with insect net. The collection of butterflies was carried out in 2 periods (2x6 = 12 days) in April-June 2019 during sunny weather from 09:00 – 12:00 of Western Indonesian Time. All butterflies were collected at ±5 m distance from the collector. The data was analysed to calculate abundance, relative abundance, frequency of the presence of butterfly, and determine diversity was conducted by using the Shannon-Wiener Index and Evenness index. The results obtained 5 families, 14 genera, 22 species, and 220 individuals consisting of 122 males and 98 females. The diversity index value obtained was 2.27 and categorised as the medium category it is mostly because, as assumed, the environmental conditions of the Air Dingin Landfills were still in good condition.

This study aimed to determine the types of Pteridophyta and to determine the index of diversity, dominance, and evenness in the Botak Hill. The research method used is descriptive quantitative. The data collection techniques in this study were exploratory methods and purposive sampling techniques. Based on the results of the study found as many as 1620 individual, consist of 24 species, 16 genera, 8 families and 4 orders. The results of the analysis of the diversity index of 2.851 (medium category), the dominance index value of 0.06 (low category), the evenness index of 0.679 (high category). There were 24 species of ferns found in Botak Hill, diversity was in the medium category, dominance was in the medium category and evenness was in the high category.

Rhizosphere Pseudomonas

We grew cucumber in pots in greenhouse for 9-successive cropping cycles and analyzed the rhizosphere Pseudomonas spp. community structure and abundance by PCR-denaturing gradient gel electrophoresis and quantitative PCR. Results showed that continuous monocropping changed the cucumber rhizosphere Pseudomonas spp. community. The number of DGGE bands, Shannon-Wiener index and Evenness index decreased during the 3rd cropping and thereafter, increased up to the 7th cropping, however, however, afterwards they decreased again. The abundance of Pseudomonas spp. increased up to the 5th successive cropping and then decreased gradually. These findings indicated that the structure and abundance of Pseudomonas spp. community changed with long-term cucumber monocropping, which might be linked to soil sickness caused by its continuous monocropping.

Distribution and habitat associations of the Critically Endangered frog Walkerana phrynoderma (Anura: Ranixalidae), with an assessment of potential threats, abundance, and morphology. Little is known about Walkerana phrynoderma, a frog endemic to the Anamalai Hills of the Western Ghats of India. Baseline information (i.e., distribution, threats, habitat characteristics, activity patterns, and relative abundance) is provided for this species, with the aim of improving our understanding of the status of the species in the wild. Visual-encounter, transect, and time-activity budget surveys were conducted in and around the Anamalai Hills of the Western Ghats. The frog skin was swabbed to determine the presence/absence of Batrachochytrium dendrobatidis, and habitat and environmental characteristics were recorded at sites where W. phrynoderma was found. These data were compared with those of sites apparently lacking this species that had suitable habitat. Walkerana phrynoderma is restricted to evergreen forests between 1300 and 1700 m a.s.l. in the Anamalai Tiger Reserve and at Munnar; thus, its range was extended from the state of Tamil Nadu to the adjoining state of Kerala. Pesticide runoff and human disturbance are the most severe threats to the species; B. dendrobatidis was not detected. This nocturnal anuran prefers forest edges and is associated with well-shaded forest foors in cool areas near freshwater streams. Walkerana phrynoderma is rarely encountered whereas its congener, W. leptodactyla, is more common. The impact of anthropogenic disturbances, especially waste disposal and development of tourism infrastructure, should be evaluated. The land that is owned by the Forest Department peripheral to the protected areas could be designated as eco-sensitive sites to prevent changes in land use that could have an adverse effect on W. phrynoderma.
