The first emerging records of a dragonfly in the dark zone of subterranean ecosystems: Exuviae and newly emerged adults of Hyrcanian Goldenring, Cordulegaster vanbrinkae in Danial Cave, northern Iran. [PDF]

Ecol Evol
The paper is about the first emerging records of an Odonata species in the dark zones of subterranean ecosystems. According to the scientific literature, the records are new for the order Odonata. Also, the study considered some behaviors of Hyrcanian Goldenring, Cordulegaster vanbrinkae in darkness.

Landscape of fear in freshwater ecotones: How predation risk and light conditions affect mesopredator activity and foraging in springs

Freshwater Biology, Volume 68, Issue 10, Page 1716-1725, October 2023., 2023
Abstract Springs are environments that can provide general insights into factors favouring diversity in ecotones, but they are often neglected in freshwater studies. One of the challenging processes acting in ecotones is the landscape of fear (LOF), the space–time variation of perceived predation risk.

Species‐specific functional traits rather than phylogenetic relatedness better predict future range‐shift responses of odonates

Insect Conservation and Diversity, Volume 16, Issue 5, Page 574-587, September 2023., 2023
The modelling results for 66 Iberian and Moroccan Odonata species predict that an increase in temperature and drought events will have a clear impact on their distribution. Species‐specific functional traits can anticipate the range‐shift responses of Odonata species, while phylogenetic relatedness is a poor predictor of their future distributions ...

What to do if streams go dry? Behaviour of Balkan Goldenring (Cordulegaster heros, Odonata) larvae in a simulated drought experiment in SW Hungary

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 ...

Litter identity mediates predator impacts on the functioning of an aquatic detritus-based food web [PDF]

, 2014
During past decades, several mechanisms such as resource quality and habitat complexity have been proposed to explain variations in the strength of trophic cascades across ecosystems.

Pierwsze stwierdzenie szklarnika leśnego Cordulegaster boltonii (Donovan, 1807) (Odonata: Cordulegastridae) w Górach Stołowych

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.

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.
