In this issue

Monkey puzzle phylogeny

Setoguchi et al., using rbcL sequences obtained from nearly all species of Araucariaceae, combine molecular and paleobotanical data to argue the phylogeny, evolutionary trends in morphological characteristics, and biogeography of this facinating Southern Hemisphere family. (see p. 1507)

Origins of marine fungi

Spatafora et al. investigated marine-terrestrial evolutionary transitions among the ascomycetes by testing the phylogenetic origins of the largest order of marine and aquatic species, the Halosphaeriales. Molecular phylogenetic analyses of the SSU (small subunit) and LSU (large subunit) rDNA strongly support multiple origins of the order from terrestrial ascomycate ancestors. (see p. 1569)

Rare invader threatens common native

The studies of Anttila et al. suggest the dark specter of a rare alien species, smooth cordgrass (Spartina alterniflora), menacing a common native, California cordgrass (S. foliosa), with hybridization. The pollen of smooth cordgrass, introduced from the Atlantic, overwhelms the stigmas of native California cordgrass, which then yield mainly hybrid seed. (see p. 1597)

Effects of wind

Cipollini characterizes the introduction of soluble peroxidase activity in leaves of bean seedings by wind-induced mechanical pertubation. The numerous ecologically important effects of wind on plant physiology are only slowly being recognized. (see p. 1586)
