- doi:10.5061/dryad.7ng0h
- 摘要：
- xual and natural selection in a scrambling damselfly. In a field setting, natural selection (survival) favored individuals with long and slender forewings and short and broad
Data from: The relationship between microhabitat use, allometry, and functional variation in the eyes of Hawaiian Megalagrion damselflies

- DOI：
- doi:10.5061/dryad.t3b51
- 摘要：
- remains an understudied question in visual ecology. Here, we use closely-related species of damselflies in the Hawaiian genus Megalagrion which diffe
Data from: Body size evolution in an old insect order: no evidence for Cope’s Rule in spite of fitness benefits of large size

- 摘要：
- : odonates (“dragonflies and damselflies”). Fossil evidence for “Cope's Rule” in odonates is weak or non-existent since the last major extinction event 65 mil
Data from: Genetic divergence predicts reproductive isolation in damselflies

- 摘要：
- ection. First, we measure reproductive isolation and genetic divergence in eight damselfly genera (30 species pairs) and test for a positive correlation. Se
Data from: Dispersal barriers and climate determine the geographic distribution of the helicopter damselfly Mecistogaster modesta
- 负责人：
- DOI：
- doi:10.5061/dryad.8tp8n
- 摘要：
- species distributions still represents a major challenge for ecologists. The Neotropical damselfly Mecistogaster modesta (Coenagrionidae: Odonata) inhabits wet
Data from: Divergence in female damselfly sensory structures is consistent with a species recognition function but shows no evidence of

- 摘要：
- thoracic plates mediate mating decisions, but is has been difficult to test this idea. Here, we use North American damselflies in the genus Enallagma
Data from: Male biased sex ratio reduces the fecundity of one of three female morphs in a polymorphic damselfly
- 负责人：
- DOI：
- doi:10.5061/dryad.t81q9
- 摘要：
- Females of the damselfly Ischnura graellsii display 3 color morphs, a male-like androchrome morph and 2 other morphs, infuscans and aurantiaca, which
Data from: Pleistocene speciation with and without gene flow in Euphaea damselflies of subtropical and tropical East Asian islands

- 摘要：
- e of homogenizing gene flow, is relatively unclear. Here, we investigated geographical modes of speciation in four closely-related Euphaea damselfly species endemic
