Abstract

Biodiversity refers to all the population species and communities in defined area. According to the recent studies, the spider plays an important role in ecological balance and considered to be the ecological indicators. Spiders are the group of terrestrial predators and complicated by their wide biodiversity strategies. There high abundance and diversity of microhabitats allow for their effective in the environment. Arthropods are mainly representing the largest number of the biotic diversity in the world. This study to focused the spider population as they represented as a invertebrate from this ecosystem. They are the important of biological indicators, they have a habitat modification due to the short generation, temperature and moisture changes. This study is attempted to investigates the identified the status of spider population and their species. The selected area in Kanyakumari district is depend on the spider fauna diversity is more or less natural habitat without much human intervention and rich in floral communities. Spiders are observed and the photograph were taken and recorded. The study was made from August to November 2022. From the study area have 60 species belonging to 25 families and 42 genera in the class of Arachnidae. Family diversity of spider species were recorded Araneidae (11 species), Sparassidae (8 species), Salticidae (8 species), Pisauridae (4 species), Lycosidae (4 species), Scycotidae (2 species), Agelenidae (2 species), Thomisidae (2 species), Theraphosidae (2 species), Oxyopidae (2 species). The study revealed that study area is consist of spider species are highest number in Araneidae family, and remaining the families are sparassidae and salticidae. The results of the study indicated the need of the conservation of biodiversity in a selected area. Spiders are an essential part of the ecosystem. They are crucial in controlling insect populations in every ecosystem and help in the crop land from predators and acts like a biological indicator. The challenges of this study could be the impact of urbanisation and urban habitats not preferable for different biological communities compared to natural habitats. Ashuman populations changing their natural habitats, the importance of spiders in natural habitat reduced the survival of spiders.

Conclusion

Spider are playing a very important role in the ecosystem. Spiders are high abundance and diversity of microhabitats allow their effect in the environment. They serve as important connection between trophic level and several are important indicators of changing the environment. Spiders are occupied by a considerable portion of animal life of the diversity of group. Arthropods are mainly representing the largest number of the biotic diversity in the world. This investigation on terrestrial spider diversity in selected area of Kanyakumari district, one with rich vegetation and another with less vegetation area proved that faunal diversity is depends to the flora diversity.
