Using functional traits and phylogeny to understand local extinction risk in dragonflies and damselflies (Odonata). [PDF]

Ecol Evol, 2022
Our results from phylogenetic generalized least squares (PGLS) models indicated that the geographical range size of species was negatively related to local extinction risk of odonates. In contrast, habitat specialist species had lower local extinction rates than habitat generalist species, and it was independent from the relatedness of species.

De status van de speerwaterjuffer Coenagrion hastulatum in Nederland, een karakteristieke libel van niet aangetaste vennen (Odonata)

, 2002
The status of the northern damselfly Coenagrion hastulatum in the Netherlands, a characteristic dragonfly of non-disturbed shallow lakes (Odonata) The northern damselfly Coenagrion hastulatum is a rare and endangered dragonfly in The Netherlands. In the period 1998-2001 extensive research had been conducted on the distribution of this species in the ...

Effects of water temperature on freshwater macroinvertebrates: a systematic review. [PDF]

Biol Rev Camb Philos Soc, 2023
ABSTRACT Water temperature is one of the main abiotic factors affecting the structure and functioning of aquatic ecosystems and its alteration can have important effects on biological communities. Macroinvertebrates are excellent bio‐indicators and have been used for decades to assess the status of aquatic ecosystems as a result of environmental ...

Highly Conserved Ecosystems Facing Climate Change: Rapid Shifts in Odonata Assemblages of Central European Bogs. [PDF]

Glob Chang Biol
This study investigated how climate change has affected species richness, composition, taxonomic diversity, functional traits, and phylogenetic patterns of species turnover of odonatofauna of Central European raised and transitional bogs over the past 25 years.

Leveraging Massive Opportunistically Collected Datasets to Study Species Communities in Space and Time. [PDF]

Ecol Lett
We present a spatiotemporal joint species distribution model to analyse large‐scale opportunistically collected biodiversity data. Our model addresses variable detection probabilities across visits and species by modelling phenological patterns and by extending the use of latent variables to characterise observer‐specific detection and reporting ...

A new statistical approach for identifying rare species under imperfect detection

Diversity and Distributions, Volume 28, Issue 5, Page 882-893, May 2022., 2022
Abstract Aim Species rarity is often used as a measure to assess the risk of extinction of species, and thus, different methods have been developed to describe the composition of rare species in biological communities. These methods usually depend on species attributes that are not always available and very often ignore imperfect species detection.

Winners and losers over 35 years of dragonfly and damselfly distributional change in Germany

Diversity and Distributions, Volume 27, Issue 8, Page 1353-1366, August 2021., 2021
Abstract Aim Recent studies suggest insect declines in parts of Europe; however, the generality of these trends across different taxa and regions remains unclear. Standardized data are not available to assess large‐scale, long‐term changes for most insect groups but opportunistic citizen science data are widespread for some.

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.

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.
