Historical changes in the phenology of British Odonata are related to climate [PDF]

, 2007
Responses of biota to climate change take a number of forms including distributional shifts, behavioural changes and life history changes. This study examined an extensive set of biological records to investigate changes in the timing of life history ...

Distribution trends of European dragonflies under climate change

Diversity and Distributions, Volume 25, Issue 6, Page 936-950, June 2019., 2019
Abstract Aim Poleward range shifts of species are among the most obvious effects of climate change on biodiversity. As a consequence of these range shifts, species communities are predicted to become increasingly composed of warm‐dwelling species, but this has only been studied for a limited number of taxa, mainly birds, butterflies and plants.

Effects of intraspecific competition on the life cycle of the stonefly, Nemurella pictetii (Plecoptera: Nemouridae) [PDF]

, 2008
Background: Considerable variation of life cycle duration in given insect species has been frequently recorded. Splitting of populations into cohorts with different life cycle lengths may occur, sometimes even between siblings from the same batch. Larval

Regional variations in occupancy frequency distribution patterns between odonate assemblages in Fennoscandia

Ecosphere, Volume 9, Issue 4, April 2018., 2018
Abstract Odonate (damselfly and dragonfly) species richness and species occupancy frequency distributions (SOFDs) were analyzed in relation to geographical location in standing waters (lakes and ponds) in Fennoscandia, from southern Sweden to central Finland. In total, 46 dragonfly and damselfly species were recorded from 292 waterbodies.

Biodiversity and ecosystem functioning in natural bog pools and those created by rewetting schemes

WIREs Water, Volume 2, Issue 2, Page 65-84, March/April 2015., 2015
Anthropogenic drainage and cutting over of peatlands have historically occurred worldwide leading to erosion, issues with water quality, loss of biodiversity, and reduced rates of carbon accumulation. In recent years, rewetting measures have attempted to address these issues.

Threats from the air: damselfly predation on diverse prey taxa [PDF]

, 2020
To understand the diversity and strength of predation in natural communities, researchers must quantify the total amount of prey species in the diet of predators.
