Dragonflies and damselflies are a charismatic, medium-sized insect order (~6300 species) with unique potential to approach comparative research questions. Their taxonomy many ecological traits for large fraction of extant species relatively well understood. However, until now, the lack large-scale phylogeny based on high throughput data connect both perspectives has precluded evolutionary quest...

The odonates shape into an order of paleopteran insects that play important role in ecosystems as they are generalist predators and some their species considered bioindicators the quality environments. establishment, care growth scientific collections include this group can promote study. To end, creation collection (COD-UAEH) Biological Research Center Autonomous University State Hidalgo is an...

This study monitors the forest ecology in Himchari National Park, Teknaf Wildlife Sanctuary, and between areas Cox's Bazar district, Bangladesh. The area has a rich biodiversity, including globally endangered species such as Asian Elephants (Elephas maximus) Boilam Trees (Anisoptera scaphula), which are threatened by anthropogenic development, newly refugees’ unplanned settlements their use of ...

Assessing a taxon’s response to change in environmental variables is fundamental knowledge understanding trends species diversity, abundance, and distribution patterns. This particularly needed on Borneo, where Odonata populations different habitats poor. To address this gap, we present the first study investigating relationship between morphology of communities heath (kerangas)-dominated mixed...

during a survey of sindh and punjab provinces of pakistan, two dragonfly genera were collected and identified for the first time from the country. anaciaeshna(family aeshnidae) is a genus of large dragonflies. representatives were collectedfrom gujjo, district thatta (sindh) in august 2008 and were identified as anaciaeshna jaspidea (burmeister). the second genus was epophthalmia (family cordul...

Cordulegaster heros is included in the EN category on IUCN Red List for territory of Czech Republic, where it inhabits an area approximately 100 km2. All localities are located forest complex Chřiby hills, and all forests fall into management forests. Most stands have a high very degree naturalness; they natural stands. The predominant units Nutrient sites middle elevations (78.2% area) Oligotr...

The number of prey killed by diverse predator communities is determined by complementarity and interference among predators, and by traits of particular predator species. However, it is less clear how predators' nonconsumptive effects (NCEs) scale with increasing predator biodiversity. We examined NCEs exerted on Culex mosquitoes by a diverse community of aquatic predators. In the field, mosqui...
