Spiracle Control in Adult Dragonflies (odonata)
Hoyle (i960) has recently shown that carbon dioxide has a direct action on the closer muscle of spiracle 2 of the desert locust, Schistocerca gregaria Forskal, reducing the electrical responses and the tension developed. Nevertheless, except in flight, the valve movements are nearly always synchronized with ventilation, and it seems unlikely that this action of carbon dioxide plays much part in...
متن کاملDragonflies (Odonata) from South-Eastern Iran
Twenty-seven species of Odonata were collected in the present survey in the freshwaters of South-Eastern Iran, Kerman province, in contrast to 11 species that were recorded previously from this region. In this study, 528 specimens were collected from more than 30 sites in Kerman province during 2006-2008. It seems that in this region due to its special biogeographic conditions, species diversit...
متن کاملDiverse circular ssDNA viruses discovered in dragonflies (Odonata: Epiprocta).
Viruses with circular ssDNA genomes that encode a replication initiator protein (Rep) are among the smallest viruses known to infect both eukaryotic and prokaryotic organisms. In the past few years an overwhelming diversity of novel circular Rep-encoding ssDNA (CRESS-DNA) viruses has been unearthed from various hosts and environmental sources. Since there is limited information regarding CRESS-...

In the first place I must express my regret that he should be unable to complete the wori^ so admirably begun, and my appreciation of my own inadequacy to continue the ser...
متن کاملThermal ecology of Interior Alaska dragonflies (Odonata: Anisoptera)
1. We examined the thermal ecology of Interior Alaska dragonflies (Odonata: Anisoptera). The relationships between mass and passive cooling rate, wing loading, minimum flight temperature (MFT) and thermoregulating ability were examined. These properties were also compared between the behavioural classes: perchers and fliers. All factors with the addition of seasonal and daily flight activity we...
