Odonata are the bioindicators of freshwater ecosystem health and is recognised as an excellent ‘flagship’ group among insects. Baseline knowledge on diversity distribution odonates over spatiotemporal scale key to biodiversity conservation. Rani Reserve Forest Assam a mosaic all habitat types suitable for odonates. The present work aims at studying Odonates in Forest. study was carried out from...

This baseline field study carried out from April 2019 to September 2020, in the Pulwama district of Kashmir Himalayan Region reported a total 11 species Odonata- under two suborders namely Anisoptera (Dragonflies: 7 genera and 9 species) Zygoptera (Damselflies: 2 each). Family Libellulidae, suborder (Dragonflies) with seven distributed five was most dominant family. Pantala flavescens common sp...

The diversity and abundance of the Odonata documented from Gangetic plain West Bengal covering two types habitats revealed its primarily aquatic nature (Oxbow Lake, Purbasthali). other sites were predominantly grasslands, with smaller water bodies around (RRS, Chinsurah DVC canal, Baidyabati). A total 40 species belonging to 31 genera 5 families, dominant families under suborders Anisoptera Zyg...

Erythrodiplax ana sp. nov. (male holotype, six male and three female paratypes), collected in Vereda wetlands (a unique Neotropical savanna environment) in Uberlândia (Minas Gerais) and Chapada dos Guimarães (Mato Grosso), Brazil, is described and illustrated. The new species fits in Borror's Basalis Group, and can be distinguished from other species by the combination of the following traits: ...

The aim of this project was to obtain a baseline understanding and investigate the concentration of mercury (Hg) in the tissue of terrestrial arthropods. The 4-month sampling campaign took place around Monterey Bay, California. Total mercury (HgT) concentrations (x ± SD, dry weight) for the captured specimens ranged from 22 to 188 ng g(-1) in the Jerusalem crickets (Orthoptera: Stenopelmatidae)...

We present estimates of lifetime reproductive success in Plathemis lydia, a territorial dragonfly. We partition the opportunity for selection into multiplicative episodes using the techniques of Arnold and Wade (1984a, 1984b) and measure selection on several morphological and behavioral characters. For both sexes, variance in survivorship was the largest contribution to variance in lifetime rep...
