Odonata: Who They Are and What They Have Done for Us Lately: Classification and Ecosystem Services of Dragonflies

Insects, 2019
Odonata (dragonflies and damselflies) are well-known but often poorly understood insects. Their phylogeny and classification have proved difficult to understand but, through use of modern morphological and molecular techniques, is becoming better ...

Diversity and Community Structure of Dragonfly and Damselfly (Odonata) at the Selorejo Waterfall Area, Ponorogo Regency, East Java Indonesia

Jurnal Riset Biologi dan Aplikasinya, 2021
Selorejo Waterfall is a natural tourism area that is quite far from downtown Ponorogo and directly adjacent to the Gunung Sigogor Nature Reserve. Hence, this area has the potential as a natural habitat for dragonfly and damselfly.

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

Diversity, 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 ...

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

Arthropods, 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.

Odonate species occupancy frequency distribution and abundance–occupancy relationship patterns in temporal and permanent water bodies in a subtropical area

Ecology 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.

The Importance of Different Biomes (Atlantic Forest, Cerrado, and Caatinga) in the Regional Structuring of Neotropical Dragonfly Assemblages

Diversity
Understanding how assemblages are structured is important for ecology, especially in tropical regions that exhibit high biodiversity and are currently experiencing high rates of loss and modification of natural environments caused by anthropogenic ...

The First Mitochondrial Genome of an Odonata Endemic to South America, Chalcopteryx rutilans (Rambur, 1842) (Odonata: Polythoridae), and Its Implications for the Phylogeny of the Zygoptera

Diversity, 2023
Chalcopteryx rutilans Rambur, 1842 (Polythoridae, Odonata) is a species widely distributed in central Amazonia. Due to its sensitivity to environmental changes, it is a bioindicator species used to evaluate the environmental conditions of streams in ...

Regional variations in occupancy frequency distribution patterns between odonate assemblages in Fennoscandia

Ecosphere, 2018
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.

Sex- and morph-specific predation risk: Colour or behaviour dependency?

European Journal of Entomology, 2004
The coexistence of discrete morphs within a species, with one morph more conspicuous than the other(s) is often thought to result from both sexual selection and predation.

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

Ecology 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.
