- 摘要:
- remains an understudied question in visual ecology. Here, we use closely-related species of damselflies in the Hawaiian genus Megalagrion which diffe

- 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

- 摘要:
- species distributions still represents a major challenge for ecologists. The Neotropical damselfly Mecistogaster modesta (Coenagrionidae: Odonata) inhabits wet

- 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

- 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
