Material composition of the mouthpart cuticle in a damselfly larva (Insecta: Odonata) and its biomechanical significance [PDF]

open access: yesRoyal Society Open Science, 2018
Odonata larvae are key predators in their habitats. They catch prey with a unique and highly efficient apparatus, the prehensile mask. The mandibles and maxillae, however, play the lead in handling and crushing the food.

\u3ci\u3eArchilestes Grandis\u3c/i\u3e in Wisconsin (Odonata: Lestidae) [PDF]

open access: yes, 2017
(excerpt) Archilestes grandis (Rambur) is the largest damselfly that occurs in America north of Mexico. Its distribution in the United States was reported by Muttkowski (1910) as Lower Sonoran, Washington to Baja California, and ...

Structuring of Dragonfly Communities (Insecta: Odonata) in Eastern Amazon: Effects of Environmental and Spatial Factors in Preserved and Altered Streams

open access: yesInsects, 2019
The evaluation of the effects of environmental factors on natural communities has been one of the principal approaches in ecology; although, over the past decade, increasing importance has been given to spatial factors.

The impacts of habitat disturbance on adult and larval dragonflies (Odonata) in rainforest streams in Sabah, Malaysian Borneo [PDF]

open access: yes, 2017
$\textbf{1.}$ Dragonfly assemblages (Odonata: comprising damselflies, Zygoptera; and dragonflies, Anisoptera) in Southeast Asian rainforests are extremely diverse but increasingly threatened by habitat disturbance, including logging and conversion of ...

Preference of larvae of Enallagma cyathigerum (Odonata: Coenagrionidae) for habitats of varying structural complexity

open access: yesEuropean Journal of Entomology, 2012
In macrophyte-rich lentic ecosystems, higher numbers of damselfly larvae occur in areas where there is structurally complex vegetation than in those where the plant architecture is relatively simple.

iNaturalist and Structured Mammal Surveys Reflect Similar Species Richness but Capture Different Species Pools Across the United States. [PDF]

open access: yesEcol Evol
iNaturalist data is widely used in ecology, but is known to contain spatial and taxa‐specific biases. We compared species richness and species pools using data from iNaturalist and structured surveys (i.e., camera traps and acoustic bat surveys) across the United States. We found that iNaturalist and structured surveys generally report similar richness,

Climate Change Is Driving Shifts in Dragonfly Species Richness across Europe via Differential Dynamics of Taxonomic and Biogeographic Groups

open access: yesDiversity, 2022
Understanding how changes in species richness pattern correlate with range changes in different taxonomic and biogeographic groups is important for conservation because it allows for generalizations about which species are at greatest risk.
