Diversity of two families Libellulidae and Coenagrionidae (Odonata) in Regional Institute of Education Campus, Bhubaneswar, Odisha, India

Journal of Threatened Taxa, 2017
Libellulidae and Coenagrionidae are the most dominant families among dragonflies and damselflies.  The present study deals with the diversity, occurrence and present status of libellulids and coenagrionids within the Regional Institute of Education ...

Differential genetic variability at two mtDNA COI regions does not imply mismatches in Odonata molecular identification performances

The European Zoological Journal, 2021
Molecular-based approaches for species identification and delimitation strongly rely, in terms of universality and efficiency, on the selected markers. Conventionally, when adopting a DNA barcoding approach to discriminate (or identify) metazoans species,

Unexpected Evolutionary Divergence of Tachykinin‐Positive Neurons Innervating the Central Complex in Hexapods [PDF]

J Comp Neurol
The central complex is a group of midline‐spanning neuropils in the brain of insects with a key role in goal‐directed orientation and navigation. Immunolabeling in 25 species, ranging from bristletails to flies, shows that neurons containing peptides of the tachykinin family of neuropeptides are present in most species studied.

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

Ecol 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,

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

Insects, 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.

Effects of geographic distance and abiotic variables on larval Odonata assemblages in western Amazon savannah lakes

Anais da Academia Brasileira de Ciências
Odonata, comprising the suborders Anisoptera and Zygoptera, are important bioindicators of aquatic ecosystem health due to their sensitivity to environmental changes.
