Questions: Is the introduced timber species Fraxinus uhdei invasive in Hawai‘i? Has logging disturbance facilitated the spread of Fraxinus and other alien species? Location: Windward Mauna Kea, island of Hawai‘i. Methods: We surveyed 29 plots which were established before selective logging of the native tree Acacia koa in 1971 to determine if Fraxinus spread beyond the borders of an existing pl...

The traps of many carnivorous plants are red in colour. This has been widely hypothesized to serve a prey attraction function; colour has also been hypothesized to function as camouflage, preventing prey avoidance. We tested these two hypotheses in situ for the carnivorous plant Drosera rotundifolia. We conducted three separate studies: (i) prey attraction to artificial traps to isolate the inf...

UNLABELLED PREMISE OF THE STUDY Microsatellite loci were developed for Vitex rotundifolia, an endangered species isolated to Lake Biwa, to investigate its genetic diversity and population structure. • METHODS AND RESULTS Ten primer sets were identified in Japanese populations of V. rotundifolia. The number of alleles per locus ranged from one to six and gene diversity per locus ranged from...

Since 1934, the rotundifolia complex of Amblycorypha has consisted of two named species:AmblycoryphaparvipennisStal, occurring fromtheMississippiRiverwestward into theeastern edges of the Great Plains, and Amblycorypha rotundifolia, occurring in most of the eastern United States. The latter entity is here shown to consist of at least three species with distinctive calling songs and different bu...
