- Hydraulic traits are influenced by phylogenetic history in the drought-resistant, invasive genus Juniperus (Cupressaceae)
[作者:Willson, CJ; Manos, PS; Jackson, RB,期刊:American Journal of Botany, 页码:299-314 , 文章类型: Article,,卷期:2008年95-3]
- In the conifer genus Juniperus (Cupressaceae), many species are increasing rapidly in distribution, abundance, and dominance in and and semiarid regions. To help understand the success of junipers in drier habitats, we s...

- A new species of aquatic plant, Scutifolium jordanicum gen. et sp. nov., Taylor, Brenner & Basha, is described from the Albian of Jordan. The leaves are microphyllous with a symmetrical, elliptical to suborbiculate shape...
- AFLP markers as a tool to reconstruct complex relationships: A case study in Rosa (Rosaceae)
[作者:Koopman, WJM; Wissemann, V; De Cock, K; Van Huylenbroeck, J; De Riek, J; Sabatlno, GJH; Visser, D; Vosman, B; Ritz, CM; Maes, B; Werlemark, G; Nybom, H; Debener, T; Linde, M; Smulders, MJA,期刊:American Journal of Botany, 页码:353-366 , 文章类型: Article,,卷期:2008年95-3]
- The genus Rosa has a complex evolutionary history caused by several factors, often in conjunction: extensive hybridization, recent radiation, incomplete lineage sorting, and multiple events of polyploidy. We examined the...
- An AFLP marker approach to lower-level systematics in Eucalyptus (Myrtaceae)
[作者:McKinnon, GE; Vaillancourt, RE; Steane, DA; Potts, BM,期刊:American Journal of Botany, 页码:368-380 , 文章类型: Article,,卷期:2008年95-3]
- Genus Eucalyptus, with over 700 species, presents a number of systematic difficulties including taxa that hybridize or intergrade across environmental gradients. To date, no DNA marker has been found capable of resolving...
- Dispersal limitations, rather than bottlenecks or habitat specificity, can restrict the distribution of rare and endemic rainforest trees
[作者:Rossetto, M; Kooyman, R; Sherwin, W; Jones, R,期刊:American Journal of Botany, 页码:321-329 , 文章类型: Article,,卷期:2008年95-3]
- Despite their narrow distribution, Australian rainforests still contain considerable levels of diversity and include many ancient, but often rare, lineages. Very little is known about the general biology of rainforest sp...
- Todea from the lower cretaceous of western North America: Implications for the phylogeny, systematics and evolution of modern Osmundaceae
[作者:Jud, NA; Rothwell, GW; Stockey, RA,期刊:American Journal of Botany, 页码:330-339 , 文章类型: Article,,卷期:2008年95-3]
- The first fossil evidence for the fern genus Todea has been recovered from the Lower Cretaceous of British Columbia, Canada, providing paleontological data to strengthen hypotheses regarding patterns of evolution and phy...
- Growth pattern and age determination for Cecropia sciadophylla (Urticaceae)
[作者:Zalamea, PC; Stevenson, PR; Madrinan, S; Aubert, PM; Heuret, P,期刊:American Journal of Botany, 页码:263-271 , 文章类型: Article,,卷期:2008年95-3]
- Cecropia species, ranging from Mexico to northern Argentina and the West Indies, are pioneer trees that colonize cleared areas with high light. To determine their ages to help pinpoint the date of the area's disturbance,...
