Voltinism of Calopteryx haemorrhoidalis, (Vander Linden) in the Sierra Morena Mountains, Southern Spain (Zygoptera: Calopterygidae): A preliminary study

Small sweep-net samples of larvae of Calopteryx haemorrhoidalis, obtained during five consecutive years from a permanent stream in the Sierra Morena Mountains, southern Spain, were combined according to month to infer the voltinism during the study period. Detailed records of head width, wing-sheath length and metamorphosis status for individual larvae are consistent with the population…

Effect of forest fires on a Mediterranean Odonata assemblage

Large-scale forest fires have shaped the Mediterranean landscape for millennia, causing a recurrent disturbance that constitutes a serious environmental issue. Following a devastating forest fire, changes in the Odonata larvae assemblage of a headwater stream were analysed during six consecutive years.

The importance of tropical mountain forests for the conservation of dragonfly biodiversity: A case from the Colombian Western Andes

Forests have been widely recognized as key habitats for odonate (dragonflies and damselflies) biodiversity, but the importance of forests for holding odonate biodiversity remains understudied in tropical mountains, one of the most diverse ecosystems on the planet. Here we describe the odonate assemblage composition along the elevation gradient in the Tatamá Mountains (Colombian Cordillera Occidental).
