Diversity of Nearctic Dragonflies and Damselflies (Odonata)
Diversity, 2022 Rarely have studies assessed Odonata diversity for the entire Nearctic realm by including Canada, the United States, and Mexico. For the first time, we explored Odonata diversity in this region according to a definition of natural community assemblages and generated species distribution models (SDMs). Species occurrence data were assembled by reviewing

X-ray phase contrast imaging of biological specimens with tabletop synchrotron radiation [PDF]
, 2011 Since their discovery in 1896, x-rays have had a profound impact on science, medicine and technology. Here we show that the x-rays from a novel tabletop source of bright coherent synchrotron radiation can be applied to phase contrast imaging of ...

Urban developmental environments alter tadpole phenotypes depending on origin
Journal of Animal Ecology, EarlyView.Urbanisation has rapidly altered the ecological and evolutionary contexts for many species. Using a reciprocal transplant experiment with frog larvae, we find that urban environments can alter morphological, developmental and behavioural traits at both ecological and evolutionary scales.

Signature of ecological partitioning in the maintenance of damselfly diversity [PDF]
Journal of Animal Ecology, 2011 1. Ecological differences among co-occurring taxa are often invoked as an explanation for the maintenance of biodiversity. Whether these differences facilitate coexistence, which allows unequal competitors to remain in systems and thus maintain biodiversity, is still unclear. 2.

Diversity of UV Reflection Patterns in Odonata
Frontiers in Ecology and Evolution, 2020 Dragonflies and damselflies (Odonata) are large-eyed diurnal insects that exhibit a variety of color patterns on their wings and/or bodies. Because Odonata can perceive light with wavelengths extending from ultraviolet (UV) to red, the color patterns ...

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 ...

Isolating the role of the matrix at patch and landscape scales
Journal of Animal Ecology, EarlyView.This is the first experimental test of the spatial scales of matrix effects. Both patch‐scale and landscape‐scale matrix influence populations through a cross‐scale interaction altering survival, reproduction, and movement. Conservation in fragmentated landscapes should consider the matrix context of patches while focusing on local matrix due to its ...

Dragonflies and Damselflies (Insecta: Odonata)
EDIS, 2019 The order Odonata contains the dragonflies and damselflies and is one of the most popular insect groups. Odonates are popular with both the amateur and professional because they are large, colorful, easily observable and have exceptionally charismatic behaviors.
