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. On the basis of these diversity maps of total, lentic and lotic diversity for the whole of the Palaearctic (excluding China and the Himalayan region) are presented.

The Importance of Different Biomes (Atlantic Forest, Cerrado, and Caatinga) in the Regional Structuring of Neotropical Dragonfly Assemblages

open access: yesDiversity
Understanding how assemblages are structured is important for ecology, especially in tropical regions that exhibit high biodiversity and are currently experiencing high rates of loss and modification of natural environments caused by anthropogenic ...

Additions to the Odonata (Insecta) fauna of Asansol-Durgapur Industrial Area, West Bengal, India

open access: yesJournal of Threatened Taxa, 2020
Previously, a total of 57 species of Odonata were reported from the Asansol-Durgapur Industrial Area, India.  In this present attempt the author reports an additional six species occurring from the same region.

Evolution determines how global warming and pesticide exposure will shape predator‐prey interactions with vector mosquitoes [PDF]

open access: yes, 2016
How evolution may mitigate the effects of global warming and pesticide exposure on predator–prey interactions is directly relevant for vector control.

Impacts of Habitat Management on Larvae of the Damselfly Coenagrion mercuriale (Coenagrionidae, Odonata)—A Laboratory Study

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Habitat management of small lotic waterbodies is essential to maintain flow and the quality of the habitats. For this purpose, aquatic plants are typically removed by authorities. This is done in a more or less disruptive manner, depending on the risk of interference with the bed.

Compensatory growth and oxidative stress in a damselfly [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2008
Physiological costs of compensatory growth are poorly understood, yet may be the key components in explaining why growth rates are typically submaximal. Here we tested the hypothesized direct costs of compensatory growth in terms of oxidative stress. We assessed oxidative stress in a study where we generated compensatory growth in body mass by exposing

Complete mitochondrial genomes of two damselfly species in coenagrionidae and phylogenetic implications

open access: yesMitochondrial DNA. Part B. Resources, 2021
Agriocnemis femina (Brauer, 1868) and Ischnura senegalensis (Rambur, 1842) are two damselflies inhabiting paddy lands. As an intermediate predator, they play an important role in controlling certain crop pest and mosquitoes.

Competition for food affects the strength of reproductive interference and its consequences for species coexistence

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Competition for food and reproductive interference (negative interspecific sexual interactions) have been identified as major drivers of species exclusion. Still, how these biotic interactions jointly determine competitive dominance remains largely unknown.

Cannibalism by damselflies increases with rising temperature [PDF]

open access: yesBiology Letters, 2017
Trophic interactions are likely to change under climate warming. These interactions can be altered directly by changing consumption rates, or indirectly by altering growth rates and size asymmetries among individuals that in turn affect feeding.
