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 ...

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.

Dragonfly functional connectivity responses are dynamic relative to drought

open access: yesInsect Conservation and Diversity, EarlyView.
During drought, dragonfly species richness decreases. Yet, dragonfly assemblages show a higher propensity for dispersal during drought. Dispersal pathways vary among the wet and dry periods, and relative to temporal changes in the landscape. While some dragonfly species can traverse plantation compartments, conservation corridors facilitate functional ...

Interplay of Diet, Heat Stress, and the Microbiome Shapes Health and Escape Behaviour in Amphibian Larvae

open access: yesEnvironmental Microbiology, Volume 28, Issue 6, June 2026.
Diet and temperature jointly shape the gut microbiome and host performance in amphibian larvae. In a multifactorial experiment with Rana temporaria, diet quality, rearing temperature, and heatwave exposure altered microbial communities and predicted metabolic pathways, while host health remained largely stable, suggesting microbiome plasticity and ...

Diverse root trait syndromes underlie species' nutrient acquisition strategies in a phosphorus‐limited forest

open access: yesEcosphere, Volume 17, Issue 5, May 2026.
Abstract Plants allocate finite carbon‐based photosynthates into root construction, mycorrhizal symbiosis, and exudate production for nutrient acquisition. Global syntheses suggest these belowground allocation constraints shape species' root trait expression and trade‐offs, yet whether similar root trait relationships occur in phosphorus (P)‐limited ...

Visual Cues Can Alter the Behavioural Responses of Dragonfly Larvae to Chemical Alarm Cues

open access: yesEthology, Volume 132, Issue 5, Page 349-358, May 2026.
Using a controlled experimental approach, we examined how chemical and visual cues influence antipredator behaviour in Aeshna cyanea larvae and tested whether risk‐related information can be socially transmitted among nearby conspecifics. Our results show that dragonfly larvae do not copy the antipredator responses of others, but visual cues alter how ...
