The Dragonflies and Damselflies (Odonata) of Utah [PDF]

open access: yesMonographs of the Western North American Naturalist, 2016
Abstract. An updated faunal list containing 94 species of Odonata (60 Anisoptera and 34 Zygoptera) for Utah is pre - sented. Of the 95 Odonata species recorded in past publications as being from Utah, 8 have been removed from the Utah Odonata list, while 7 new state records have been added.

Improving the Accuracy of Species Identification by Combining Deep Learning With Field Occurrence Records

open access: yesFrontiers in Ecology and Evolution, 2021
Citizen science is essential for nationwide ecological surveys of species distribution. While the accuracy of the information collected by beginner participants is not guaranteed, it is important to develop an automated system to assist 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.

THE DRAGONFLIES AND DAMSELFLIES OF NEBRASKA

open access: yesZea Books, 2019
Odonates of Nebraska The Nebraska odonate list has 109 species in two suborders, damselflies (Zygoptera) with 47 species and dragonflies (Anisoptera) with 62 species. Nebraska had been very poorly surveyed prior to 2005 and 63 counties had fewer than 10 records.

Allozyme and mitochondrial DNA variability within the New Zealand damselfly genera Xanthocnemis, Austrolestes, and Ischnura (Odonata) [PDF]

open access: yes, 2007
We collected larval damselflies from 17 sites in the North, South and Chatham Islands, and tested the hypotheses that: (1) genetic markers (e.g., allozymes, mtDNA) would successfully ¬discriminate taxa; and (2) the dispersal capabilities of adult ...

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.

Recent progress on the flight of dragonflies and damselflies [PDF]

open access: yesInternational Journal of Odonatology, 2020
Remarkable flight performance is key to the survival of adult Odonata. They integrate varied three-dimensional architectures and kinematics of the wings, unsteady aerodynamics, and sensory feedback control in order to achieve agile flight. Therefore, a diverse range of approaches are necessary to understand their flight strategy comprehensively ...

Historical changes in the phenology of British Odonata are related to climate [PDF]

open access: yes, 2007
Responses of biota to climate change take a number of forms including distributional shifts, behavioural changes and life history changes. This study examined an extensive set of biological records to investigate changes in the timing of life history ...
