With a total of 75 species the odonate diversity in the Namibian desert is surprisingly high. Based on their distribution characteristics, invasion patterns, and breeding success, there are six well-defined categories of Odonata: widespread species – (1) permanently living in the desert, and desert biased, (2) permanently living in the desert, but not desert-biased; (3)…
Climate change brings with it unprecedented rates of increase in environmental temperature, which will have major consequences for the earth’s flora and fauna. The Odonata represent a taxon that has many strong links to this abiotic factor due to its tropical evolutionary history and adaptations to temperate climates. Temperature is known to affect odonate physiology…
This paper, a companion to Part I which treated status and distribution of Numidian Odonata, summarizes current knowledge of their seasonal ecology and identifies areas where promising research avenues exist. Annual patterns of adult occurrence and reproductive activity are used to infer life cycles, with particular reference to strategies that enable species to bridge the…
Orthetrum julia (Kirby 1900), subspecies falsum Longfield 1955, is reported for the first time from Yemen and the Arabian Peninsula (1 male, Wadi al-Ahjar, 15°27’53″N 43°52’32″E). The specimen is described and compared with specimens from Africa; taxonomically relevant structures are figured. The total number of species known from Yemen is raised to 37, from the…
