Results showed that seasonal variation of species composition was not remarkable. The species whose dominance was the highest in those seasons were Sagitta enflata in summer, Sagitta nagae in winter and spring and Sagitta bedoti in autumn.

结果表明，毛颚类优势种季节交替不明显，优势度最高的种分别是：夏季肥胖箭虫、冬、春季海龙箭虫和秋季百陶箭虫。

Seed germination rate and germination speed and seedling root length are more sensitive to the extract than the other index. Allelopathy on Ligularia sagitta is different among the species tested in this study, Thermopsis lanceolata, Stellera chamaejasme, Aconitum sinomontanum, Ipornoea cairica, Ajania tenuifolia and Wedelia trilobata show better result. New natural herbicides may be developed from these 6 species.

不同供体植物对箭叶橐吾化感抑制程度不同，披针叶黄华、狼毒、高乌头、五爪金龙、细叶亚菊和南美彭琪菊的作用效果非常显著（综合化感效应指数M0.50），这6种植物有望开发天然除草剂。

In the second section, we describe two novel species that were isolated from the Chigu and Szutsao saltern. On the basis of phenotypic, phylogenetic and genetic analyses, these two strains were considered to represent a novel species of the genus Virgibacillus and Marinobacter, and were named Virgibacillus chiguensis and Marinobacter szutsaonensis according to Chigu and Szutsao saltern.

本研究亦从盐田分离出两株极端耐盐菌，经由型态、生理、生化及分子演化等多重分析比对，确认这两株菌株为新菌种，分别依其分离之盐田命名为七股菌与四草菌，并寄存於菌种保存研究中心。

About 25 species: tropical Asia ranging through India to Samoa; four species in China.

It is caused by Malassezia spp., which is the normal human saprophyte. Under certain conditions, both exogenous and endogenous, the fungus can convert from a yeast to a pathogenic mycelial form. Since the taxonomy of Malassezia spp. has recently been modified to include 7 species, there are several reports on the species from the PV scales, but the results are different.

在一定外源性和内源性因素下可引起花斑癣(Pityriasis Versicolor， PV)，新的分类方法将马拉色菌分为7个种以来，从PV患者分离到菌种构成的研究国内外均有报道，但结果很不一致，以往的研究方法多为培养法，受不同菌种的生长速度不同，以及存在菌种的覆盖和培养基选择性等因素的影响。

A total of 803 sawfly specimen belonging to 121 species, 58 genera and 3 families were collected, and the dominant and widespread species were Claremontia sinobirmana Malaise and Nesoselandria southa Wei.

统计分析表明，异鳞纹眶叶蜂(Claremontia sinobirmana Malaise)和南华平缝叶蜂为优势种和广布种。
