Area and the rapid radiation of Hawaiian Bidens (Asteraceae)
Remote islands have played a central role in the development of evolutionary theory, particularly with regard to the factors responsible for speciation and adaptive radiation (Darwin, 1859; Lack, 1947; Carlquist, 1974; Schluter, 2000). The Hawaiian Islands (about 4000 km from the nearest land mass) are noteworthy in this regard, as adaptive radiation is Department of Biology, Stanford Universit...
متن کاملRevision of endemic Marquesas Islands Bidens (Asteraceae, Coreopsideae)
During the preparation of the Vascular Flora of the Marquesas Islands four new species of Bidens (Coreopsideae, Asteraceae) have come to light and are described herein: Bidens woodii W.L. Wagner, J.R. Clark & Lorence, sp. nov. from Ua Pou, and Bidens microcephala W.L. Wagner, J.R. Clark & Lorence sp. nov., Bidens evapelliana W.L. Wagner, J.R.

متن کاملMicrosatellite markers for the invasive species Bidens alba (Asteraceae)1
UNLABELLED PREMISE OF THE STUDY Microsatellite markers were developed in the invasive species Bidens alba (Asteraceae) to assess its population structure and to facilitate tracking its expansion in China. • METHODS AND RESULTS Using 454 pyrosequencing, 20 microsatellite primer sets were developed for B. alba. The markers were tested on one population of B. alba (30 individuals) and one pop...
متن کاملGenetics of adaptive radiation in Hawaiian and Cook Islands species of Tetramolopium (Asteraceae; Astereae). I. Nuclear RFLP marker diversity.
Thirty-three nuclear RFLP (restriction fragment length polymorphism) probes were used to study genetic diversity in Hawaiian and Cook Islands species of Tetramolopium for comparison with previous morphological and isozyme studies and to provide greater resolution of the events associated with adaptive radiation in the genus. Levels of RFLP diversity are greater than those reported for isozymes,...
متن کاملBidens meyeri (Asteraceae, Coreopsideae): a new critically endangered species from Rapa, Austral Islands
Bidensmeyeri (Asteraceae/Compositae) is described and illustrated from Rapa, Austral Islands, (French Polynesia). This new species is presumed to be most closely related to Bidenssaint-johniana from nearby Marotiri Island. Bidensmeyeri may be distinguished from Bidenssaint-johniana based on the length of the peduncle (3 cm versus 10 cm), apex of the inner involucral bracts (glabrous vs. puberul...
