Firstly, an invasive species must be invasive enough in itself or has some biological distinction, such as quantitative and qualitative differences in the genome, or patterns of recombination. Secondly, to invade successfully, a new environment for an invasive species must be invasible, and this we may call the ecological basis of invasion. An invasive species may need to establish new interactions with other species, especially those mutualistic relations such as animal related pollination, seed dispersal by animals, mycorrhizal fungi, and symbioses between plants and nitrogen fixing bacteria.

首先从其自身来说，需要有足够的入侵性，这可以认为是入侵种的生物学基础，可能表现为具有多倍性、一定的遗传变异、杂合性或表型可塑性，以及不同的交配系统等；其次一个物种的入侵成功还取决于入侵生境的可入侵性，这可以认为是入侵种的生态学基础，而新的种间关系的形成，尤其是入侵种与其他种类的互惠共生关系的建成是关键。

U 2+, Co 2+ and Mn 2+ whose concentrations were 40, 40, 20μg·L -1 respectively could increase the AKP activity significantly in mysis, but higher con...

o2 +在 2 0μg·L-1时明显提高两种酶的活性。而Ni2 +只使两种酶活性降低。鉴于碱性磷酸酶和ATPase与生长发育直接相关，金属离子对对虾幼体生长的影响与对两种酶活性的影响基本一致，因此体内这两种酶活性的高低可作为判别环境因素是否适合对虾幼体生存的指标。

In D3 gene with 5 site mutations. There exists individual variation in the COII gene, but this variation is less than that among other members of Myzomyia Series such as An. aconitus, An. jeyporiensis, etc. In addition, one haplotype different from both An. minimus A and C was found in these 3 genes studied.②The genetic distance between An. minimus A and An. minimus C is less than that among other members of Myzomyia Series. Molecular trees based on different genes and different methods show that An.

种系发生研究表明，微小按蚊复合体亲缘种A、C间的遗传距离远小于与之近缘的同系其它成员间的距离。2个分子标记3种方法构建的基因树显示，微小按蚊A、C的种系地位非常固定，不同地域来源、不同变异类型的微小按蚊始终在同一分&枝&上，与迈蚊系其它成员相比，呈现其相对稳固的单源性。

In this work, venoms were collected from adult Naja atra in Zhejiang Province and Naja kaouthia in Yunnan Province, well identified by morphological characters and cytochromeb gene analysis in summer season to avoid age and seasonal variation in the venom composition.

该工作首先采集夏季的眼镜蛇种，进行分类学的鉴定，以排除因为种属分类、季节和年龄而导致的不确定因素对蛇毒成分产生影响。再从鉴定好的成年浙江舟山种和云南孟加拉种眼镜蛇蛇毒中分离获得短链神经毒素；同时采用RT PCR方法得到相应的基因。

Ophyra aenescens (Wiedemann,1830),which distributed in Palaearctic,Nearctic,Australia and Neotropic Regions,but not known to China before,was recently found in Shanghai,China.It was also intercepted from waste paper in a cargo from America and Australia.The present paper deals with the diagnostics,biology,distribution and others of the species.

2001年3月在浦东国际机场附近一孔雀尸体上发现1种中国前所未见的黑蝇，被疑为近年从境外传入，该种黑蝇被鉴定为古铜黑蝇〔 Ophyra aenescens (Wiedemann，1830)〕，原产于美洲，可携带脊髓灰质炎病毒、沙门菌、志贺菌等，是一种重要的病媒性蝇类；2002～2004年在上海其他地区的调查中，也采到了该种；上海口岸于2003年12月22日从美国和2005年4月22日从澳大利亚的入境废纸中先后截获该蝇。

Based on above studies, some main conclusions were obtained as follows : 1 the diatoms forming mats in low latitude west pacific is"shade flora"diatom Ethmodiscus rex Hendey; 2 the sites found diatom mats are zone distributed, the direction is NW-SE and most distribute in the deep water area with flat seafloor, between 17°N～20°N and the water depth 4837-6150 m below Carbonate Compensation Depth (CCD 3) AMS 14C dates show that the sediments rich in diatom mats occurred during 16.0 ~ 28.6 ka B.P., which means the bloom mainly occurred in last glacial maximum, while there are not diatom mats deposits in other layers; 4 A total of 101 diatom taxa belonging to 40 genera had been identified from the 155 samples in the two cores WPD 03 and WPD 12, and the relative percentage of Thalassionema frauenfeldii are the highest, Thalassionema nitzschioides、Azpeitia nodulifera、Hemidiscus cuneiformis、Nitzschia marina take the second place.

14C年期间，即&勃发&发生于末次冰期最盛期；4在WPD 03和WPD 12两个岩芯共155个样品中共鉴定硅藻40属101种，且Thalassionema frauenfeldii的相对百分含量最高，Thalassionema nitzschioides、Azpeitia nodulifera、Nitzschia marina、Hemidiscus cuneiformis等次之，这五种硅藻占整个硅藻物种相对百分含量的85%左右，说明在该海域表层水体硅藻席沉积过程中，这五种硅藻最容易与成席硅藻在同时期的环境中生存，形成勃发；5MIS3期的晚期，该区域表层海水盐度降低，这有助于该区水体的成层化，从而使&树荫种&硅藻开始勃发，导致&秋季倾泻&；6末次冰期由于南极中层水北扩，南大洋中层水将富含硅酸盐的海水带入了研究区，即南大洋的&硅溢漏&作用，使该区域硅藻得以勃发，同时，铁输入的增多，可能也是造成硅藻勃发的主要原因之一。

In this study, isobaric tags for relative and absolute quantification labeling coupled with two-dimensional liquid chromatography-tandem mass spectrometry (2D-LC-MS/MS) was employed to compare the differential protein expressions in MCF7 cells upon 17β-oestradiol (E2) stimulation or serum deprivation versus in normal conditions. A total of 576 proteins with the confidential level of ≥95% were identified, 26 proteins among the 576 proteins were found to be differentially expressed after E2 stimulation or serum deprivation, and among them 10 proteins were up-regulated and 16 proteins were down-regulated by more than two folds.
