Calopteryx Damselfly Dispersions Arising from Multiscale Responses to Landscape Structure

open access: yesEcology and Society, 2000
Using spatially explicit simulation models, we explored the extent to which fine-scale (i.e., meters to tens of meters) movement behaviors could be used to predict broader scale patterns of distribution on heterogeneous landscapes.

Dragonflies and damselflies of the St Katherine Protectorate

open access: yesEgyptian Journal of Biology, 2015
The indigenous Bedouin tribes of South Sinai (Egypt) irrigate small gardens for agricultural purposes and this has been shown to boost the biodiversity of plants, birds and insects, including dragonflies (Odonata). The gardens offer water-related resources normally in short supply in arid regions.

Plant structural complexity and mechanical defenses mediate predator-prey interactions in an odonate-bird system. [PDF]

open access: yes, 2017
Habitat-forming species provide refuges for a variety of associating species; these refuges may mediate interactions between species differently depending on the functional traits of the habitat-forming species.

Spectral Sensitivities and Color Signals in a Polymorphic Damselfly

open access: yesPLoS ONE, 2014
Animal communication relies on conspicuous signals and compatible signal perception abilities. Good signal perception abilities are particularly important for polymorphic animals where mate choice can be a challenge. Behavioral studies suggest that polymorphic damselflies use their varying body colorations and/or color patterns as communication signal ...
