Effects of Temperature and Rainfall Pattern on The Abundance of Orthopteran Insects in Coal Mines Ecological Restoration Areas of Jharia Coal Fields, Jharkhand, India

Abstract

Ecological restoration on coal mines' overburden dumps provides a suitable environment for the study of primary succession. The Abundance and diversity study of orthopteran insects and their diversity pattern with temperature and rainfall provides a lot about the stage of succession and ecosystem complexity in the area. Orthopteran diversity of two sites covering ten years of plantation having different types of vegetation were monitored. Tropical conditions like changes in rainfall and temperature influence the abundance of insects. An increase in monsoon increases the abundance whereas as the temperature increases the abundance decreases. In herbaceous habitats, insects’ diversity increases which gives a recolonization pattern for the ecosystem. This helps to increase the livelihood and conservation of the ecosystem and directs to sustain the SDG 15 goal.
