Evaluating Conservation Corridor Success for Rare and Common Dragonflies Using Zeta Diversity. [PDF]

open access: yesEcol Evol
This study applied the zeta diversity framework to evaluate how conservation corridors in South African timber plantations impact dragonfly assemblages, finding that corridors function similarly to natural habitats. The research findings showed that dragonfly species richness was higher in corridors than in natural areas, consistently declining with ...

Unexpected Evolutionary Divergence of Tachykinin-Positive Neurons Innervating the Central Complex in Hexapods. [PDF]

open access: yesJ Comp Neurol
The central complex is a group of midline‐spanning neuropils in the brain of insects with a key role in goal‐directed orientation and navigation. Immunolabeling in 25 species, ranging from bristletails to flies, shows that neurons containing peptides of the tachykinin family of neuropeptides are present in most species studied.

Macroevolution of Steep Interspecific Metabolic Allometry in an Old Insect Order. [PDF]

open access: yesEcol Lett
We investigated the macroevolution of metabolic allometry in an old insect order (Odonata: dragonflies and damselflies) to test the hypothesis that metabolic scaling exponents reflect evolutionary constraints and a general slope of 0.75 on a log–log scale.

Metacommunity patterns of Amazonian Odonata: the role of environmental gradients and major rivers [PDF]

open access: yesPeerJ, 2019
Background We identified and classified damselfly (Zygoptera) and dragonfly (Anisoptera) metacommunities in Brazilian Amazonia, relating species distribution patterns to known biological gradients and biogeographical history.

The odonatan insects from the Paleocene of Menat, central France [PDF]

open access: yesActa Palaeontologica Polonica, 2022
The current knowledge on the Paleocene Odonata is rather limited despite the fact that it is a crucial period for the history of this order. An overview of the fossil odonatans from the Paleocene of Menat (France) is provided.

First record of Odonata nymphs from Karun River, south-west Iran [PDF]

open access: yesIranian Journal of Animal Biosystematics, 2014
Odonata fauna is poorly known in Iran and most of the previous studies deal with northern parts of the country, studying adult specimens. We sampled Karun River for aquatic insects in the city of Ahvaz in south-west of Iran during 2009–2011. As a result,

Diversity of Palaearctic Dragonflies and Damselflies (Odonata)

open access: yesDiversity, 2022
More than 1.2 million distribution records were used to create species distribution models for 402 Palaearctic species of dragonflies and damselflies.

The use of crotalaria as possible indirect agent to control Aedes aegypti L. (Diptera: Culicidae)

open access: yesEntomoBrasilis, 2020
Aedes aegypti L. (Diptera: Culicidae) is a vector of arboviruses associated with dengue, chikungunya, zika and yellow fever. Based on empirical knowledge, plants belonging to genus Crotalaria (Fabaceae) attract dragonflies, which are the main natural ...
