[Addition effects of co-expansion of two bamboos on plant diversity in broad-leaved forests].

The effects of Phyllostachys edulis and Oligostachyum oedogonatum expansion on species diversity of broad-leaved forests were investigated in Wuyishan National Nature Reserve, Jiangxi Province, China. Ph. edulis and/or O.

[Scaling relationships between twig size and leaf size of Pinus hwangshanensis along an altitudinal gradient in Wuyi Mountains, China.].

To analyze the tradeoff relationship between twigs and leaves, the traits of Pinus hwang-shanensis including leaf area, leaf number, twig length and twig diameter were investigated in Wuyi Mountains along an altitudinal gradient. The results indicated that leaf number, twig length, twig diameter, leafing intensity and twig stem cross-sectional area of P. hwangshanensis increased gra-dually with the increasing altitude, while individual leaf area decreased gradually.

Development of microsatellite loci for Cephalotaxus oliveri (Cephalotaxaceae) and cross-amplification in Cephalotaxus.

Premise Of The Study: Microsatellite loci were developed for Cephalotaxus oliveri, an endemic and endangered conifer in China, which will allow assessment of the levels of genetic diversity and a means to understand the genetic consequences of habitat fragmentation.

Methods And Results: Using the Fast Isolation by AFLP of Sequences COntaining (FIASCO) Repeats protocol, 19 microsatellite loci were identified in C. oliveri, 13 of which were polymorphic within a sample of 52 individuals representing five natural populations.
