Flight of the dragonflies and damselflies [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2016
This work is a synthesis of our current understanding of the mechanics, aerodynamics and visually mediated control of dragonfly and damselfly flight, with the addition of new experimental and computational data in several key areas.

Male coercion and convenience polyandry in a calopterygid damselfly [PDF]

Journal of Insect Science, 2002
Copulation in odonates requires female cooperation because females must raise their abdomen to allow intromission. Nevertheless in Calopteryx haemorrhoidalis haemorrhoidalis (Odonata) males commonly grasp ovipositing females and apparently force copulations.

Nonadaptive radiation in damselflies [PDF]

Evolutionary Applications, 2015
AbstractAdaptive radiations have long served as living libraries to study the build‐up of species richness; however, they do not provide good models for radiations that exhibit negligible adaptive disparity. Here, we review work on damselflies to argue that nonadaptive mechanisms were predominant in the radiation of this group and have driven species ...

European database of the life-history, morphological and habitat characteristics of dragonflies (Odonata)

European Journal of Entomology, 2020
Climate change and an ever-increasing effect of humans on the great majority of freshwater ecosystems have affected not only individual organisms but also the links between them. In order to effectively protect communities or entire freshwater ecosystems,

The dragonflies and damselflies (Odonata) of Angola [PDF]

African Invertebrates, 2017
Prior to 2012, only 158 species of Odonata were known from Angola. Surveys in 2012 and 2013 added 76 species and two further additions in 2016 brought the national total to 236 species. We provide a revised checklist with taxonomic notes and discuss the history of research, the biogeography of the fauna, and the potential for further discoveries.

Molecular and Morphological Analyses Support Different Taxonomic Units for Asian and Australo-Pacific Forms of Ischnura aurora (Odonata, Coenagrionidae)

Diversity, 2022
Despite the great technological progress that has aided taxonomical identification, taxonomical issues remain for certain species found in remote and/or understudied geographical areas. The damselfly species Ischnura aurora has been the subject of a long-

A List of the Odonata of the La Rue-pine Hills Ecological Area [PDF]

, 2017
A survey of the adult odonate fauna of the La Rue-Pine Hills Ecological Area, Union County, Illinois, was conducted during 1983-1985. Thirty six. species were collected including the damselfly Telebasis byersi Westfall; this damselfly is known to occur ...

Damselfly eggs alter their development rate in the presence of an invasive alien cue but not a native predator cue

Ecology and Evolution, 2021
Biological invasions are a serious problem in natural ecosystems. Local species that are potential prey of invasive alien predators can be threatened by their inability to recognize invasive predator cues.

Study design and mark-recapture estimates of dispersal: A case study with the endangered damselfly Coenagrion mercuriale [PDF]

, 2012
Accurate data on dispersal ability are vital to the understanding of how species are affected by fragmented landscapes. However, three factors may limit the ability of field studies to detect a representative sample of dispersal events: (1) the number of

The impacts of environmental warming on Odonata: a review [PDF]

, 2008
Climate change brings with it unprecedented rates of increase in environmental temperature, which will have major consequences for the earth's flora and fauna.
