Description of the final instar larva of argia serva hagein selys, 1865 (Odonata coenagrionidae) [PDF]

, 2018
The American genus Argia, with more than 100 species described, is the most speciose genus of Odonata in the world. In this contribution, the final stadium larva of Argia serva, the southernmost distributed species of Argia, is described and diagnosed ...

Colonization and extinction mediate environmental effects on the phylogenetic diversity of invertebrate communities

Ecology, Volume 107, Issue 5, May 2026.
Abstract Phylogeny offers a powerful framework for understanding mechanisms driving community assembly. Yet, most empirical studies in community phylogenetics rely on observational approaches. In this study, we explore how two important drivers of community assembly—habitat size and predator presence—shape species richness and phylogenetic relatedness ...

Demography and Behaviour of Teinopodagrion oscillans (Odonata: Megapodagrionidae) in a Protected Area of the Colombian Andean Region

Insects
The demography and behaviour of Teinopodagrion oscillans was studied in a protected area in the Andean region of Colombia. Adult damselflies were individually marked, and using their recapture histories, we estimated survival, longevity, sex ratio, and ...

X-ray phase contrast imaging of biological specimens with tabletop synchrotron radiation [PDF]

, 2011
Since their discovery in 1896, x-rays have had a profound impact on science, medicine and technology. Here we show that the x-rays from a novel tabletop source of bright coherent synchrotron radiation can be applied to phase contrast imaging of ...

Exposure of Larvae of the Solitary Bee Osmia bicornis to the Honey Bee Pathogen Nosema ceranae Affects Life History [PDF]

, 2019
Wild bees are important pollinators of wild plants and agricultural crops and they are threatened by several environmental stressors including emerging pathogens. Honey bees have been suggested as a potential source of pathogen spillover.

When Similar Individuals Don't Attract: Absence of Assortative Mating by Coloration in a Damselfly With Honest Signaling

Ethology, Volume 132, Issue 5, Page 305-316, May 2026.
In Acanthagrion lancea damselflies, both sexes display blue ornamentation, but do they choose mates based on it? We tested whether mutual mate choice and time constraints influence ornament evolution. Blue coloration correlated with individual quality, but individuals did not choose mates based on color, and this was unaffected by time constraints over

Water availability and land‐use shape the diversity of Odonata in the Middle East

Insect Conservation and Diversity, Volume 19, Issue 3, Page 621-633, May 2026.
Odonata diversity in the Middle East depends on the availability of long‐lasting waters, emphasizing the importance of preserving stable aquatic habitats for biodiversity conservation under climate change‐driven droughts. Agricultural expansion is associated with increased Odonata species richness, but overall trait diversity remains limited ...
