Diagnostic Efficacy of Morphological Characters of Larval \u3ci\u3eTramea Lacerata\u3c/i\u3e Hagen and \u3ci\u3eTramea Onusta\u3c/i\u3e Hagen (Odonata: Libellulidae) in the Prairie Region of Missouri [PDF]

, 2018
Distinguishing among species of larvae of the dragonfly genus Tramea historically has been problematic, largely due to conflicting characterizations of the larvae of T. lacerata Hagen and T. onusta Hagen (Odonata: Libellulidae) in the literature.

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.

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,

Efficacy of Morphological Characters for Distinguishing Nymphs of \u3ci\u3eEpitheca Cynosura\u3c/i\u3e and \u3ci\u3eEpitheca Spinigera\u3c/i\u3e (Odonata: Corduliidae) in Wisconsin [PDF]

, 2018
Attempts to distinguish exuviae and last-instar nymphs of Epitheca cynosura (Say) and Epitheca spinigera (Selys) (Odonata: Corduliidae) using lateral spine characters have proven to be unreliable, and recent use of setae counts on only one side of the ...
