The impacts of habitat disturbance on adult and larval dragonflies (Odonata) in rainforest streams in Sabah, Malaysian Borneo [PDF]

open access: yes, 2017
Summary Dragonfly assemblages (Odonata: comprising damselflies, Zygoptera; and dragonflies, Anisoptera) in Southeast Asian rainforests are extremely diverse but increasingly threatened by habitat disturbance, including logging and conversion of forest ...

Response of adult dragonflies to artificial prey of different size and colour.

open access: yesPLoS ONE, 2017
Aposematism is an evolved, cross-species association between a preys' unprofitability and the presence of conspicuous signals. Avian predators have been widely employed to understand the evolution of these warning signals However, insect predators are ...

Flight of the dragonflies and damselflies [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2016
This work is a synthesis of our current understanding of the mechanics, aerodynamics and visually mediated control of dragonfly and damselfly flight, with the addition of new experimental and computational data in several key areas.

Evolutionary history and divergence times of Odonata (dragonflies and damselflies) revealed through transcriptomics

open access: yesiScience, 2021
Summary Dragonflies and damselflies are among the earliest flying insects with extant representatives. However, unraveling details of their long evolutionary history, such as egg laying (oviposition) strategies, is impeded by unresolved phylogenetic ...

Diversity of Nearctic Dragonflies and Damselflies (Odonata)

open access: yesDiversity, 2022
Rarely have studies assessed Odonata diversity for the entire Nearctic realm by including Canada, the United States, and Mexico. For the first time, we explored Odonata diversity in this region according to a definition of natural community assemblages ...

Sex-specific ornament evolution is a consistent feature of climatic adaptation across space and time in dragonflies

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2021
Significance One of biology’s most pressing goals is to understand how organisms adapt to their climates. Researchers have greatly clarified the ways that organisms evolve to improve their survival in warmer climates, yet a major gap in our knowledge ...

A Review of the Impacts and Opportunities for African Urban Dragonflies

open access: yesInsects, 2021
Simple Summary The expansion of urban areas in combination with climate change places great pressure on species found in freshwater habitats. Dragonflies are iconic freshwater organisms due to their large body sizes and striking coloration.

Comparative phylogeography uncovers evolutionary past of Holarctic dragonflies

open access: yesPeerJ, 2021
Here, we investigate the evolutionary history of five northern dragonfly species to evaluate what role the last glaciation period may have played in their current distributions.
