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

Ecol 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]

J 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]

Ecol 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.

A checklist of chromosome numbers and a review of karyotype variation in Odonata of the world [PDF]

Comparative Cytogenetics, 2020
The ancient insect order Odonata is divided into three suborders: Anisoptera and Zygoptera with approximately 3000 species worldwide each, and Anisozygoptera with only four extant species in the relict family Epiophlebiidae.

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

PeerJ, 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]

Acta 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]

Iranian 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,

Aeshna affinis Vander Linden, 1820 (Odonata: Aeshnidae) in the Iberian Peninsula: A review of past and recent records, and a larval biometric study

Revista Chilena de Entomología, 2023
Aeshna affinis, known as “Southern Migrant Hawker, Blue-eyed Hawker” is a native odonate species uncommon in many areas of the Iberian Peninsula. Field observations in Andalusia, the southernmost peninsular region, are notably scarce. Several photographs
