The Effects of Microplastics and Additives on Ecosystem Function, Structure, and Signaling

open access: yesGlobal Change Biology, Volume 32, Issue 8, August 2026.
Microplastics disrupt ecosystem signaling through olfactory traps, altering predator–prey signaling and disrupting microbial communication and quorum sensing. ABSTRACT Microplastics (MPs) and their associated chemical additives are pervasive contaminants whose ecological impacts extend beyond organismal toxicity to fundamentally alter ecosystem ...

The Transcriptomic Response Along an Urbanization Gradient Is Also Temperature‐Dependent in a Freshwater Insect

open access: yesMolecular Ecology, Volume 35, Issue 16, August 2026.
ABSTRACT Urbanization has become one of the leading causes of habitat transformation affecting ecosystem functioning. However, the transcriptomic response to urbanization remains poorly understood. Here, we conducted a transcriptomic analysis along an urbanization gradient under different warming temperatures.

The complete mitochondrial genome of Enallagma cyathigerum (Odonata: Coenagrionidae) and phylogenetic analysis

open access: yesMitochondrial DNA. Part B. Resources, 2017
To better understand the diversity and evolution of Odonata, we sequenced and annotated the complete mitochondrial genome (mitogenome) of Enallagma cyathigerum. This mitogenome was 16,661 bp in size and encoded the typical 37 genes, i.e.

Dragonflies and damselflies (Odonata) in urban ecosystems: A review

open access: yesEuropean Journal of Entomology, 2016
The expansion of urban areas is one of the most significant anthropogenic impacts on the natural landscape. Due to their sensitivity to stressors in both aquatic and terrestrial habitats, dragonflies and damselflies (the Odonata) may provide insights ...

Climatic drivers prevail in montane and lowland Odonata latitudinal diversity gradients, but human modification erodes lowland patterns

open access: yesEcography, Volume 2026, Issue 7, July 2026.
Latitudinal diversity gradients (LDGs) arise from the interplay of historical, ecological, and evolutionary processes, yet these drivers may differ across landforms. Mountains, with steep elevational and climatic gradients, often sustain distinct diversity dynamics compared with adjacent lowlands, where vertical climatic gradients are weak and human ...

Increased duration of extreme thermal events negatively affects cold acclimation ability in a high-latitude, freshwater ectotherm (Ischnura elegans; Odonata: Coenagrionidae)

open access: yesEuropean Journal of Entomology, 2020
Instances of heat waves and cold snaps are becoming more frequent and of increasing duration worldwide. It is well established that short exposure to high or low-temperatures, such as during extreme weather events, often results in adaptive (acclimation ...

Evidence consistent with local adaptation to predation shaping stabilizing effects underlying local coexistence

open access: yesEcosphere, Volume 17, Issue 7, July 2026.
Abstract Trait divergence in resource use and susceptibility to predation can promote local competitor coexistence if such divergence generates demographic advantages when species are rare, producing frequency‐dependent stabilizing effects. These effects may vary spatially as populations experience different ecological conditions shaping species ...

A global systematic review of the effects of hydromorphological floodplain restoration on biodiversity

open access: yesJournal of Applied Ecology, Volume 63, Issue 7, July 2026.
Our evidence synthesis reinforces the notion that hydromorphological floodplain restorations, as a biodiversity conservation measure or NbS, can significantly enhance local floodplain biodiversity. However, such benefits were often compromised at least in part by invasive species post‐restoration, highlighting the importance of sustained management ...
