Odonata assemblages in anthropogenically impacted lotic habitats

Journal of Limnology, 2020
Increasing human pressures have a negative impact on freshwater habitats and their biota worldwide. To protect habitats and the species contained within them, ecological assessments over a gradient of near natural to degraded freshwater habitats are ...

Comparative analysis of immune responses in ovipositing and non‐ovipositing females of European earwig Analyse comparative de la réponse immunitaire avant et après la ponte chez le forficule européen

Physiological Entomology, EarlyView.
Oviposition and care decrease the total haemocyte concentration. Oviposition and care affect haemocyte type proportions. Serratia marcescens challenge does not affect the immune cell parameters. Abstract Reproduction and immunity are essential biological processes that compete for resources and energy.

Long‐Term Population Declines of Habitat‐Shifting Species in the City: A Living Planet Index Approach for Berlin, Germany

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
We applied two global biodiversity indices at a city scale and revealed significant declines in odonate and amphibian populations in freshwater systems over several decades. Our study demonstrates the effectiveness of both indices as a baseline for fulfil urban‐related biodiversity framework targets if suitable biodiversity time series are available ...

Eco‐evolutionary context modifies a destructive plant invader's response to climate

New Phytologist, Volume 251, Issue 5, Page 2980-2994, September 2026.
Abiotic environment–fitness relationships can be shaped by evolutionary, ecological, and eco‐evolutionary contexts. Summary Understanding the relationship between climate and fitness will be important when predicting how plant populations respond to climate change. We conducted a replicated common garden experiment (4 sites × 2 yr) with 96 genotypes (n

Diversity of Odonates (Odonata, Anisoptera & Zygoptera) in the Theniet El ‎Had National Park-North West of Algeria [PDF]

Journal of Insect Biodiversity and Systematics, 2023
The aim of this study is to make an inventory of the fauna of the Odonata in Theniet El Had National Park, which helps managers to make appropriate decisions for the conservation of these species. The site is entirely forested (Cedrus and Quercus species)

The Odonate fauna (Insecta: Odonata) of Belihuloya, southern intermediate zone of Sri Lanka: A preliminary assessment and conservation implications

Journal of Asia-Pacific Biodiversity, 2022
Belihuloya situated in a biogeographical transition zone in south-central Sri Lanka is being threatened by land-use changes. Establishing baseline biodiversity knowledge of an indicator taxon within this lesser explored area, the present study ...

Continental accumulation of fads2 copy numbers allows sticklebacks to thrive across a diversity of nutritional landscapes

Oikos, Volume 2026, Issue 8, August 2026.
Nutrients, including vital organic compounds, vary in availability across ecosystems, with the potential to act as a source of selection for traits that increase nutrient acquisition and biosynthesis. Compared to freshwaters, marine ecosystems are richer in the omega‐3 long‐chain polyunsaturated fatty acid (n‐3 LC‐PUFA) docosahexaenoic acid (DHA ...

BIMr2: Inference of migration rates and their drivers from multilocus genotypes

Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2330-2342, August 2026.
Abstract Understanding how environmental factors drive recent migration is crucial for predicting species' responses to habitat change and for informing conservation strategies. There is one method available (BIMr) aimed at identifying the environmental factors associated with migration patterns using genetic data.

An experimental examination of dispersal decisions made by flight‐capable heteropteran insects in urban stormwater pond conditions

Ecological Entomology, Volume 51, Issue 4, Page 672-689, August 2026.
Salty conditions in urban stormwater ponds can influence dispersal timing in species‐specific ways for actively dispersing aquatic heteropteran insects. Assaying multiple aspects of dispersal propensity, Hesperocorixa obliqua emigrated earlier in stormwater pond conditions while overall probabilities remained unchanged; Notonecta undulata emigration ...

A preliminary investigation on wing morphology, flight patterns, and flight heights of selected odonates

Journal of Threatened Taxa
Wing shape and its individual structural components are a major contributor to the flight performance of odonates. Two essential components of wing structure are the nodus and the pterostigma.
