Study design and mark-recapture estimates of dispersal: A case study with the endangered damselfly Coenagrion mercuriale [PDF]

, 2012
Accurate data on dispersal ability are vital to the understanding of how species are affected by fragmented landscapes. However, three factors may limit the ability of field studies to detect a representative sample of dispersal events: (1) the number of

Differing Impacts of Livestock Farming and Ranching on Aquatic Insect Biodiversity: A Global Meta‐Analysis

Global Change Biology, Volume 31, Issue 9, September 2025.
This meta‐analysis investigates the impact of livestock farming and ranching on the abundance and richness of major aquatic insect orders. Livestock farming significantly reduced the richness of Ephemeroptera, Plecoptera, and Trichoptera. However, livestock farming did not significantly impact abundance, suggesting finite shifts in aquatic insect ...

The complete mitochondrial genome of Ceriagrion fallax (Odonata: Zygoptera: Coenagrionidae) and phylogenetic analysis

Mitochondrial DNA. Part B. Resources, 2021
Ceriagrion fallax is ubiquitous in south China and is particularly easy be found in some rice fields. In this study, we sequenced and analyzed the complete mitochondrial genome (mitogenome) of C. fallax.

Golf courses and wetland fauna [PDF]

, 2009
Golf courses are often considered to be chemical-intensive ecosystems with negative impacts on fauna. Here we provide evidence that golf courses can contribute to the support and conservation of wetland fauna, i.e., amphibians and macroinvertebrates ...

Small whiteface (Leucorrhinia dubia: Odonata) reintroduction update highlights the importance of long‐term monitoring and regular habitat management

Insect Conservation and Diversity, Volume 18, Issue 5, Page 859-868, September 2025.
In 2001, 80 larvae of Leucorrhinia dubia were translocated from degraded raised bog in Slovakia to the newly created peatbog pools in Czechia, and the population has been regularly monitored. Based on the capture‐mark‐recapture and exuviae surveys in 2015 and 2024, the population size is stable, comprising ca.

Field estimates of reproductive success in a model insect: behavioural surrogates are poor predictors of fitness [PDF]

, 2011
Understanding, and therefore measuring, factors that determine fitness is a central problem in evolutionary biology. We studied a natural population of Coenagrion puella (Odonata: Zygoptera) over two entire breeding seasons, with over a thousand ...

Thermal Plasticity in a Cross‐Sexual Transfer Trait: Geographic Variation and Phenotypic Integration of Blue Wing Colour in Female Butterflies

Ecology Letters, Volume 28, Issue 8, August 2025.
We provide a first test whether female colour variation in common blue butterflies (a) has arisen through cross‐sexual transfer. Analyses of museum specimens (b) show that the distribution of females wing colour varies in a geographic mosaic pattern, and laboratory experiments (c) show that this variation is both genetically determined and impacted by ...

Diversity of odonata in Danau Kemiri Pagardewa and adjacent areas, Lubai Ulu, Muara Enim, South Sumatera [PDF]

BIO Web of Conferences
The existence and diversity of Odonata can provide information for habitat management planning, particularly regarding their role in the food chain and their potential as bioindicators in both aquatic and terrestrial habitats.

Fossil gaps inferred from phylogenies alter the apparent nature of diversification in dragonflies and their relatives [PDF]

, 2011
Background The fossil record has suggested that clade growth may differ in marine and terrestrial taxa, supporting equilibrial models in the former and expansionist models in the latter. However, incomplete sampling may bias findings based on fossil data

Assessing predation pressure of Vespa velutina on local fauna through DNA metabarcoding

Journal of Zoology, Volume 326, Issue 4, Page 329-338, August 2025.
This study investigates the predation pressure exerted by the invasive yellow‐legged hornet (Vespa velutina) on native insect populations in Mallorca, using DNA metabarcoding to analyze their diet. Results reveal a diverse prey spectrum, including key insect groups such as Apidae (bees), Calliphoridae (blowflies), and Vespidae (wasps), with no ...
