Higher gregarine parasitism often in sibling species of host damselflies with smaller geographical distributions [PDF]

open access: yes, 2012
1. This study investigated inter-specific variation in parasitism by gregarines (Eugregarinorida: Actinocephalidae), among sibling species of damselflies (Odonata: Zygoptera), in relation to relative size of geographical ranges of host species.

Impact of a small artificial water source on the diversity of odonates (Insecta : Odonata) in an urban landscape [PDF]

open access: yesArthropods, 2021
Rapid urbanisation is mainly responsible for the degradation and fragmentation of natural ecosystems in urban areas. Dragonflies and damselflies (Odonata) constitute an important part of urban biodiversity.

open access: yesEcology and Evolution, 2020
This paper investigates species richness and species occupancy frequency distributions (SOFD) as well as patterns of abundance–occupancy relationship (SAOR) in Odonata (dragonflies and damselflies) in a subtropical area.

Thermal response of two sexually dimorphic Calopteryx (Odonata) over an ambient temperature range

open access: yesEcology and Evolution, 2020
Organisms may internally or behaviorally regulate their body temperatures or conform to the ambient air temperatures. Previous evidence is mixed on whether wing pigmentation influences thermoregulation in various odonates.

Study design and mark-recapture estimates of dispersal: A case study with the endangered damselfly Coenagrion mercuriale [PDF]

open access: yes, 2012
Accurate data on dispersal ability are vital to the understanding of how species are affected by fragmented landscapes. However, three factors may limit the ability of field studies to detect a representative sample of dispersal events: (1) the number of

Sequence Analysis of the Cytochrome C Oxidase Subunit I Gene of Pseudagrion pilidorsum (Odonata: Coenagrionidae)

open access: yesMakara Journal of Science, 2017
Pseudagrion pilidorsum is 1 of over 140 species of Pseudagrion (in the family Coenagrionidae), the largest genus of damselfly. This species exhibits dimorphism due to the different body colorations of males and females, making them difficult to ...

First Record of Microsporidia Infection in the Damselfly Ischnura elegans Larvae: Temperature and Predator Cue Effects on the Host’s Life History

open access: yesDiversity, 2022
Here, we report, for the first time, a microsporidian infection in laboratory-reared larvae of the damselfly Ischnura elegans. Infected larvae originated from field-collected adult females, which were caught in southern Poland in August 2020 (the second ...
