Nonadaptive radiation in damselflies [PDF]

open access: yesEvolutionary 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 ...

Flight of the dragonflies and damselflies [PDF]

open access: yesPhilosophical 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. These are: the diversity of dragonfly wing morphologies, the aerodynamics of gliding flight, force generation in flapping

Inter-annual variation in prevalence and intensity of mite parasitism relates to appearance and expression of damselfly resistance

open access: yesBMC Ecology, 2010
Background Insects can resist parasites using the costly process of melanotic encapsulation. This form of physiological resistance has been studied under laboratory conditions, but the abiotic and biotic factors affecting resistance in natural insect ...

Odonata (Insecta) diversity of Kuldiha Wildlife Sanctuary and its adjoining areas, Odisha, eastern India

open access: yesJournal of Threatened Taxa, 2018
A study was carried out to assess the Odonata fauna of Kuldiha Wildlife Sanctuary, Odisha, eastern India from November 2012 to October 2013.  During the study a total of 54 species of odonates including 37 species of dragonflies (Anisoptera) and 17 ...

Interaction between juvenile narrow-claw crayfish, Astacus leptodactylus (Eschscholtz), and common water frog, Rana esculenta (L.), tadpoles or common blue damselfly, Enallagma cyathigerum (Charpentier), larvae during rearing under controlled conditions

open access: yesArchives of Polish Fisheries, 2014
Interactions were studied among juvenile narrow-claw crayfish, Astacus leptodactylus (Eschscholtz), and common water frog, Rana esculenta (L.), tadpoles and common blue damselfly, Enallagma cyathigerum (Charpentier), larvae during rearing under ...

Odonata of Maludam National Park, Sarawak, Malaysia

open access: yesJournal of Threatened Taxa, 2015
This paper presents records of Odonata collected in July 2012 in Maludam National Park, Sarawak, Malaysia. A total of 48 species from nine families were collected. Three species were new to science, one of which has already been described as Prodasineura

Analysis of adult damselfly fecal material aids in the estimation of antibiotic-resistant Enterobacterales contamination of the local environment [PDF]

open access: yesPeerJ, 2018
Because damselflies are ubiquitously but focally present in natural environments and play a critical role as predators of other insect species, the fecal matter of damselflies may be useful for investigating antibiotic-resistant bacterial populations ...

Aquatic Macrophyte Vegetation Promotes Taxonomic and Functional Diversity of Odonata Assemblages in Intermittent Karst Rivers in the Mediterranean

open access: yesDiversity, 2022
Assemblages of adult Odonata were studied in four intermittent karst rivers encompassing macrophyte-rich (MRH) and macrophyte-poor habitats (MPH) in southern Europe, where temporary lotic habitats are the predominant freshwater type but are still ...

Age-dependent induction of immunity and subsequent survival costs in males and females of a temperate damselfly

open access: yesBMC Ecology, 2006
Background To understand variation in resistance to parasites within host populations, researchers have examined conditions under which immunity is induced and/or is costly.

A Bibliometric Analysis of the Global Research in Odonata: Trends and Gaps

open access: yesDiversity, 2022
Insects of the order Odonata have been used as indicators of environmental quality in different aquatic systems around the world. In this context, we conducted a bibliometric analysis to understand the general patterns of research on Odonata published in
