An overview is given of the present knowledge and current research on the Odonata fauna of Turkey, Iran, and the Caucasus. The occurrence of endemic taxa and of rare and possibly threatened species is discussed. The use of water from various aquatic habitats is reviewed in order to gain insight in existing and potential problems,…
Recent studies have indicated that frequent anthropogenic disturbances in tropical developing countries are primary drivers of reduction in community diversity and local extinction of many arthropods, including dragonflies. We assessed the impact of anthropogenic disturbances on odonate assemblages across three different land use types, in a biodiverse nature reserve in Ghana. A total of 37…
Oviposition behaviour by Sympetrum frequens, a species endemic to Japan, has been observed throughout its entire breeding season, which extended for about one month after the harvest of rice. Approximately 50% of oviposition events occurred during the first week of the reproduction period. Sunny oviposition sites were preferentially selected by ovipositing pairs. The starting time…
