Biogeographic regionalization of Odonata (Insecta) in the Neotropics: contrasting Anisoptera and Zygoptera spatial patterns [PDF]

open access: yesFrontiers of Biogeography
The Neotropical region stands as a significant hotspot for Odonata diversity, yet comprehensive spatial patterns have remained less elucidated. This study aimed to provide a comprehensive biogeographical regionalization of the order Odonata across the ...

Nuevos Zygoptera y Anisoptera (Insecta: Odonata) en el Cretácico inferior de España

open access: yesEstudios Geologicos, 1993
El estudio de nuevos insectos cretácicos hallados en los yacimientos de calizas litográficas españoles ha dado como resultado el reconocimiento de tres nuevas formas de odonatos (Insecta, Odonata).

Setting boundaries: Environmental and spatial effects on Odonata larvae distribution (Insecta)

open access: yesAnais da Academia Brasileira de Ciências, 2015
Environmental characteristics and spatial distances between sites have been used to explain species distribution in the environment, through Neutral (space) and Niche theory (environment) predictions. We evaluated the effects of spatial and environmental

The development of sexual differences in body size in Odonata in relation to mating systems

open access: yesEuropean Journal of Entomology, 2007
Adult body size is the result of important environmental, maternal and/or genetic effects acting on animals during development. Here we investigate how sexual size dimorphism (SSD) develops in seven species of Odonata: Anax imperator, Cordulegaster ...

Material composition of the mouthpart cuticle in a damselfly larva (Insecta: Odonata) and its biomechanical significance [PDF]

open access: yesRoyal Society Open Science, 2018
Odonata larvae are key predators in their habitats. They catch prey with a unique and highly efficient apparatus, the prehensile mask. The mandibles and maxillae, however, play the lead in handling and crushing the food.

Odonata (Insecta) Communities in a Lowland Mixed Mosaic Forest in Central Kalimantan, Indonesia

open access: yesEcologies, 2023
Assessing a taxon’s response to change in environmental variables is fundamental knowledge to understanding trends in species diversity, abundance, and distribution patterns.

Structuring of Dragonfly Communities (Insecta: Odonata) in Eastern Amazon: Effects of Environmental and Spatial Factors in Preserved and Altered Streams

open access: yesInsects, 2019
The evaluation of the effects of environmental factors on natural communities has been one of the principal approaches in ecology; although, over the past decade, increasing importance has been given to spatial factors.

Preference of larvae of Enallagma cyathigerum (Odonata: Coenagrionidae) for habitats of varying structural complexity

open access: yesEuropean Journal of Entomology, 2012
In macrophyte-rich lentic ecosystems, higher numbers of damselfly larvae occur in areas where there is structurally complex vegetation than in those where the plant architecture is relatively simple.

Climate Change Is Driving Shifts in Dragonfly Species Richness across Europe via Differential Dynamics of Taxonomic and Biogeographic Groups

open access: yesDiversity, 2022
Understanding how changes in species richness pattern correlate with range changes in different taxonomic and biogeographic groups is important for conservation because it allows for generalizations about which species are at greatest risk.

Effects of geographic distance and abiotic variables on larval Odonata assemblages in western Amazon savannah lakes

open access: yesAnais da Academia Brasileira de Ciências
Odonata, comprising the suborders Anisoptera and Zygoptera, are important bioindicators of aquatic ecosystem health due to their sensitivity to environmental changes.
