… state 0 through state 1 to state 2 on a single branch); hence, branch support is best expressed
in terms of character state changes (increase in length required to lose a branch; Bremer, …

Amino acid sequence data are available for ribulose biphosphate carboxylase, plastocyanin,
cytochrome c, and ferredoxin for a number of angiosperm families. Cladistic analysis of the …

Asterids comprise 1/4–1/3 of all flowering plants and are classified in 10 orders and >100
families. The phylogeny of asterids is here explored with jackknife parsimony analysis of …

Oogenesis in Drosophila involves specification of both germ cells and the surrounding
somatic follicle cells, as well as the determination of oocyte polarity. We found that two …

This is a detailed study of understanding in a second language, related to the actual lives of
minority workers. The focus is on everyday interactions between these workers and the …

… We find Cyperaceae 36 Myr older than did Bremer, a difference probably due to differences
in sampling. Bremer sampled eight taxa of Cyperaceae compared with 48 in our analysis. …

The search for centers of origin has fallen into disrepute because of unfounded assumptions
and spurious criteria. Nevertheless, a proper approach to understanding ancestral areas …

Background The aim of this pilot study was to investigate the effects of four weeks of an oral
health optimized diet on periodontal clinical parameters in a randomized controlled trial. …

A new method, PATHd8, for estimating ultrametric trees from trees with edge (branch) lengths
proportional to the number of substitutions is proposed. The method allows for an arbitrary …

… These methods postulate some small number k > 1 of fixed but different rates and place
each branch into one of these k rate categories (Hasegawa et al., 1989; Uyenoyama, 1995; …
