Ecological Entomology, Volume 45, Issue 6, Page 1457-1465, December 2020., 2020 Approximately 15% of Cordulegaster heros larvae are capable of surviving 3 weeks without surface water under laboratory conditions. The survival probability was significantly increased if animals burrowed into the sediment. Survival probability was higher on fine substrate material. Size of the larvae only affected the burrowing depth.

A cost-effective method to quantify biological surface sediment reworking [PDF]
, 2013 We propose a simple and inexpensive method to determine the rate and pattern of surface sediment reworking by benthic organisms. Unlike many existing methods commonly used in bioturbation studies, which usually require sediment sampling, our approach is ...

The development of sexual differences in body size in Odonata in relation to mating systems
European Journal of Entomology, 2007 Adult body size is the result of important environmental, maternal and/or genetic effects acting on animals during development. Here we investigate how sexual size dimorphism (SSD) develops in seven species of Odonata: Anax imperator, Cordulegaster ...

Fragmenta Naturae, 2023 Paper presents the first record in the Stołowe Mountains of a rare, protected by law Golden-ringed Dragonfly Cordulegaster boltonii. One specimen was hunted by a domestic cat in 2022 in Łężyce village. The presented locality (c. 600m a.s.l.) is one of the most elevated localities of this species in Poland.

Morphological adaptations of the mouthparts to the ectoparasitic lifestyle of the biting midge Forcipomyia paludis (Diptera: Ceratopogonidae), specialized in Odonata [PDF]
, 2022 Damselflies and dragonflies are well-known hosts of the West Palaearctic biting midge Forcipomyia paludis. Females of this ectoparasitic dipteran mainly cling to the host’s wings, sucking hemolymph from the wing veins.

The influence of relief morphometric characteristics upon the occurrence of the species Cordulegaster bidentata in the particular conditions of the Western Carpathians [PDF]
, 2021 The study concerns a monitoring survey of Cordulegaster bidentata Selys, 1843 (Odonata, Cordulegastridae), which is considered near threatened in the European Red List of Dragonflies, in order to show its habitat preferences and clarify the influence of ...

Biological Invasion and Coexistence in Intraguild Predation
Journal of Applied Mathematics, Volume 2013, Issue 1, 2013., 2013 Invasion of an exotic species initiated by its local introduction is considered subject to intraguild predation (IGP). Mathematically, the system dynamics is described by three nonlinear diffusion‐reaction equations in two spatial dimensions. The key factors that determine successful invasion are investigated by means of extensive numerical simulations.
