1. Factors affecting outcomes of territorial contests in the Formosan Damselflies, Euphaea formosa
Euphaea formosa (Odonata: Zygoptera: Euphaeidae) is an endemic damselfly species with wide distribution in streams of Taiwan. In this study, the first aim is to describe in details of territorial behavior in this species. We conducted behavioral observations between July and September 2006 and 2007 in Wu Chen River, near Lian Hwa Chih of central Taiwan. The results indicates that the frequency of territorial fights was at peak around 09:00-12:00 and positively correlated with temperature. There are four distinct behavioral stages in a typical male-male encounter: aggression, hover, chase, and flight in 8-shape. Our second aim is to investigate what factors affect the outcome of a territorial contest. The results indicate that residents of a territory win significantly more fights than intruders. Body size, wing area, percentage of pigmentation on hindwings, body fat, and flight muscle ratios were not significantly different between winners and losers.
2. The Tempo and Mode of Pronotal Evolution in Membracis Treehoppers
Cope’s rule refers to a phyletic trend of increase in body size over geological time. Despite the rule has been proposed more than a century ago, its validity is still controversial. Treehoppers in the Neotropical genus, Membracis (Insecta: Membracidae) have an enlarged, laterally flattened pronotum which is an ideal trait for studying character evolution. Our preliminary results showed that phylogenetic history has a minimal effect on pronotal shape. Evolution of pronotal shape was directly proportional to tree branch lengths, and the mode of pronotal evolution is gradual. Our current view of how pronota evolved needs further revisions with additional data.
