Phylogenetic Analysis and Fossil Plants
Stein Jr., W.E., 1987. Phylogenetic analysis and fossil plants. Rev. Palaeobot. Palynol., 50:31 61. This paper presents a perspective on the relat ionship between cladistic methods and the study of fossil plants. Paleobotany has been slow in evaluat ing the potent ial of these and other explicit methods compared to other branches of systematics. However, the unique or part icular ly difficult p...
متن کاملComparative Assessments of Fossil Fuel Power Plants
Studies of CO2 capture and storage (CCS) costs necessarily employ a host of technical and economic assumptions regarding the particular technology or system of interest, including details regarding the capture technology design, the power plant or gas stream treated, and the methods of CO2 transport and storage. Because the specific assumptions employed can dramatically affect the results of an...
متن کاملFossil Plants of the Group Cycadofilices
filices " embraces a number of Paleozoic generic types combining structural characters of the ferns and of the gymnosperms. As originally established by Potonie 1 it was confined chiefly to genera founded on petrified trunks, petioles, and roots, with the provisional reference of several frond types. Subsequent research has established the correlation of the fronds of several of the members, an...

متن کاملAtmospheric benzenoid emissions from plants rival those from fossil fuels
Despite the known biochemical production of a range of aromatic compounds by plants and the presence of benzenoids in floral scents, the emissions of only a few benzenoid compounds have been reported from the biosphere to the atmosphere. Here, using evidence from measurements at aircraft, ecosystem, tree, branch and leaf scales, with complementary isotopic labeling experiments, we show that veg...
