Can damselfly larvae serve as bioindicator species for assessing contamination of organophosphate esters in aquatic environments?

open access: yesEcological Indicators
Damselfly larvae have been widely used to evaluate the environmental quality of freshwater ecosystems. However, there have been limited studies on the pollution characteristics of organophosphate esters (OPEs) in damselfly larvae. This study investigated

Retrospection of Research on Dragonfly and Damselfly (Odonata) During Past Fifty Years: A Bibliometric Review [PDF]

open access: yesInsects
Dragonflies and damselflies (Odonata) play important roles in ecology and are used as model organisms in evolutionary studies, but a comprehensive overview of Odonata research has been lacking.

Similar Survival Rates of Territorial and Sneaker Males in a Polymorphic Damselfly: A Multi‐Year Study [PDF]

open access: yesEcology and Evolution
Male alternative reproductive tactics (ARTs) have been documented across diverse taxa and typically involve a male morph that defends resources to attract females and an alternate morph that exploits this behavior to obtain matings by stealth ...

Predatory Potential of Nymphal Odonates on Aedes aegypti Developing in Freshwater and Brackish Water Habitats [PDF]

open access: yesInsects
Aedes aegypti, the primary vector of dengue, undergoes preimaginal development in brackish water (BW). However, dengue vector control exclusively targets freshwater (FW) habitats.

Levels and Spatial Patterns of Effective Population Sizes in the Southern Damselfly (Coenagrion mercuriale): On the Need to Carefully Interpret Single‐Point and Temporal Estimations to Set Conservation Guidelines [PDF]

open access: yesEvolutionary Applications
The effective population size (Ne) is a key parameter in conservation and evolutionary biology, reflecting the strength of genetic drift and inbreeding.

A Comparison of Wing Shape and Size in Andromorph and Gynomorph Females with Males of Calopteryx Intermedia Using Geometric Morphometrics [PDF]

open access: yesتاکسونومی و بیوسیستماتیک, 2021
Female polymorphism is visible in some populations of Odonata species for unknown reasons. In general, one of the female forms which is more or less similar to males is called andromorph. Andromorph females show similar color patterns and sometimes, even

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 ...

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

open access: yesDiversity, 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-
