The Oracle of Delphi—a molecular phylogenetic approach to Greek Cordulegaster Leach in Brewster, 1815 (Odonata: Anisoptera: Cordulegastridae) [PDF]
Zootaxa, 2022 Taxonomy of the genus Cordulegaster Leach in Brewster, 1815 in Greece is not completely understood. The taxonomic status of the subspecies C. helladica buchholzi (Lohmann, 1993), C. helladica kastalia (Lohmann, 1993), and C. heros pelionensis Theischinger, 1979 was still unclear.

International Journal of Odonatology, 2023 Some structural characters, such as wing venation, have been used in odonates to differentiate taxa. In Cordulegaster boltonii, a species widely distributed throughout the western Palaearctic, the main characteristics of its wing venation have not been quantified until now.

Ecology and Evolution, Volume 10, Issue 16, Page 8936-8948, August 2020., 2020 We quantified the color lightness and body volume of 99 European dragon‐ and damselflies (Odonata) and combined this trait information with survey data for 518 local assemblages across Europe to test whether trait‐environment relationships previously reported at coarse spatial scales also hold for spatially explicit local assemblages.

International Journal of Odonatology, 2022 Within wide geographical areas, Odonata populations can show biometric differences as a consequence of both biotic (e.g., predation, competition) and abiotic factors (mainly temperature). These differences can occur in the larval stage, although reliable characters are needed to detect differences. We analyzed whether Cordulegaster boltonii larvae from

A dark colour form of Cordulegaster heros (Odonata: Cordulegastridae) [PDF]
Casopis slezského zemského muzea (A), 2011 A dark colour form of Cordulegaster heros (Odonata: Cordulegastridae) In July 2010 a dark colour form of the male of Cordulegaster heros was recorded at the Kamenný potok stream in the village of Modra-Piesok in the southern part of the Malé Karpaty Mts. in Slovakia.

Ecology and Evolution, Volume 9, Issue 3, Page 1410-1430, February 2019., 2019 Predator–prey relationships are important ecological interactions, affecting biotic community composition and energy flow through a system. This study used sequences from the 18S V9 rRNA barcoding region to identify prey items in the gastrointestinal (GI) tracts of predators taken from the Black River, Cheboygan Co., MI (n = 367 samples, 12 predator ...
