影响舟山群岛蛙类物种多样性的主要因素分析

分析了面积、海拔高度、离物种源的最小距离、岛屿形状和人类活动对舟山群岛蛙类物种多样性的影响。结果显示,物种多样性与岛屿面积和最高海拔明显相关。但物种多样性与离物种源的最小距离没有显著相关性,这说明岛屿形成后蛙类在岛屿间（或岛屿和大陆间）很少发生迁移和再定居,物种数处于“非平衡”状态。岛屿形状不影响物种多样性。人类活动对物种多样性影响较小,原因是舟山群岛没有专一性的林栖种类,除淡肩角蟾外,其余种类均能生活于农田栖息地。我们认为,岛屿面积是舟山群岛蛙类物种多样性的主要决定因素和最佳预测者。

A study on interaspecific biodiversity of eight groups of silkworm （Bombyx mori） by biochemical markers

The recognition of biodiversity in different races and lines of silkworm (Bombyx mori) is very useful for breeding programs and production of high efficiency hybrids. In this study eight groups of silkworm were selected including 103, 107, Xihang 1 and 2 of Japanese origin and 104, 110, Koming 1 and 2 of Chinese origin. The activity levels of three enzymes including alkaline phosphatase, alanine aminotransferase and aspartate aminotransferase in haemolymph of fifth instar larva were measured. Moreover, the quantitative amount of total protein, cholesterol and glucose of haemolymph was evaluated.The data reveal that the activity level of measured macromolecules except for alkaline phosphatase were significantly different in all the groups. Hierarchical agglomerative clustering under UPGMA model separated line 104 from other groups. Two groups of Koming 1 and Xihang 1 had the most intergroup similarities.     

Sexual Dimorphism in Mass of the Hindlimb Muscles of the Piebald Odorous Frog （Odorrana schmackeri）

Male-biased sexual dimorphism in hind limb muscles is widespread in anuran species where scramble competition is common among males. Such sexual difference is thought to result from sexual selection. In this view, we tested the differences in muscle mass between the sexes and between amplectant and non-amplectant males by quantifying the mass of four hindlimb muscles （triceps femoris, sartorius, gracilis and plantaris longus） of females and males of Odorrana schmackeri. The results showed that females significantly exceeded males for muscle triceps femoris, gracilis, plantaris longus and total mass when controlled for body size. There are no significant differences between amplectant and non-amplectant males. It is probable that the maintenance of the amplectant position in O. schmackeri may depend on the strength of hindlimb muscles in females to support the pair.

Analysis of forestry impacts and biodiversity in two Pyrenean forests through a comparison of moth communities （Lepidoptera, Heterocera）

We have compared the biodiversity variations in moth communities between unmanaged forests and commercial forests in a mountainous environment （Pyrenees France）. The aim was to evaluate the impact of forestry activities on moth diversity. The data collected from the insects were analysed with a Bayesian specific similarity index （noted SSP index） and by statistical biodiversity indexes comparison. It was seen that diversity and richness were decreased in the plantation compared to the unmanaged forest. Interestingly, the composition of the communities of moths was shown to be not only related to the presence/absence of host plants, but also to be in relation with changes in the differences in forest architecture （i.e. the relative coverage by the different vegetation levels）. However, the moth community in the commercial forest still has a high capacity to converge with the moth community present in more natural forests. We report here a list of 177 species of moths, providing information on the distribution of some uncommon species, poorly studied as yet in the Pyrenees.     

The nest architecture of the ant, Pheidole oxyops Forel, 1908 （Hymenoptera： Formicidae）

Pheidole oxyops builds subterranean nests, with an external architecture that is distinctive and easily recognizable by its wide and specific entrance hole, measuring up to 12.2 cm in diameter, denoting a pitfall-trap. In order to study the nests＇ internal architecture, seven nests were excavated; four were identified with neutral talc, while the others were cast in cement and then excavated. Measurements were made in order to gain a better understand- ing of their structures, and a photographic documentation was obtained as well. The excavations revealed that the nests are perpendicular relative to the ground, beginning with a cylindrical channel with a mean length of 13.5 cm, containing irregular formations, and whose diameter becomes progressively narrower until the first chamber is formed. As the channel continues, dish-like chambers appear, interconnected by channels that become progressively narrower and longer, while the chambers are arranged at greater distances from each other as nest depth increases. Both channels and chambers are located on the vertical projection of the entrance hole. Nests may reach a depth of up to 5.09 m, with a number of chambers ranging between 4 and 14.

The Functional Role of the Hollow Region of the Butterfly Pyrameis atalanta （L.） Scale

Questions concerning the functional role of the hollow region of the butterfly Pyrameis atalanta （L.） scale are experimentally investigated. Attention was initially directed to this problem by observation of the complex microstrucmre of the butterfly scale as well as other studies indicating higher lift on butterfly wings covered with scale. The aerodynamic forces were measured for two oscillating scale models. Results indicated that the air cavity of an oscillating model of the Pyrameis atalanta （L.） scale increased the lift by a factor of 1.15 and reduced the damping coefficients by a factor of 1.38. The modification of the aerodynamic effects on the model of butterfly scale was due to an increase of the virtual air mass, which influenced the body. The hollow region of the scale increased the virtual air mass by a factor of 1.2. The virtual mass of the butterfly scale with the hollow region was represented as the sum of air mass of two imaginary geometrical figures： a circular cylinder around the scale and a right-angled parallelepiped within the hollow region. The interaction mechanism of the butterfly Pyrameis atalanta （L.） scale with a flow was described. This novel interaction mechanism explained most geometrical features of the airpermeable butterfly scale （inverted V-profile of the ridges, nozzle of the tip edge, hollow region, and openings of the upper lamina） and their arrangement.     

Reappraisal of Microtropis macrocarpa C.Y. Cheng ＆ T.C. Kao （Celastraceae）, a critically endangered species endemic to Yunnan,China

Microtropis macrocarpa C.Y. Cheng ＆ T.C. Kao has been treated as a synonym of Microtropis macrophylla Merr. ＆ Freeman in most taxonomic reports in China. According to our study, M. macrocarpa is an independent species endemic to Yunnan, China. Microtropis macrophylla and Microtropis pachyphylla Merr. ＆ Freeman should be treated as synonyms of Microtropis longifolia Wall. ex Kurz. M. macrocarpa is also identified as a critically endangered species, CR B lab （i,ii,iii,v）, based on the IUCN Red List Categories and Criteria. The foliar surface, anther and pollen structures were also observed with a scanning electron microscope.     

The human leucocyte differentiation antigens （HLDA） workshops： the evolving role of antibodies in research, diagnosis and therapy

The 8^th International Workshop on Human Leucocyte Differentiation Antigens （chaired by HZ and managed by BS） was run over a 4-year period and culminated in a conference in December 2004. Here we review the achievements of the HLDA Workshops and provide links to information on CD molecules and antibodies against them, including the 93 new CDs assigned in the 8^th Workshop. We consider what remains to be achieved （including an estimate of the number of leucocyte surface molecules still to be discovered）, and how the field can best move forward.

Association of aphid life stages using DNA sequences： A case study of tribe Eriosomatini （Hemiptera： Aphididae Pemphiginae）

Association of aphid life stages based on a portion of COI sequence was applied in Eriosomatini. Three aphid specimens, nos. 17496, 19265a, and 19265b collected on Gramineae roots all clustered with Tetraneura chinensis Mordvilko with strong support. The average pairwise p-distance among the four taxa was 0.001 （range, 0.000-0.002）, and that among all the ingroup taxa was 0.065 （range, 0.000-0.141）. This indicated that nos. 17496 and 19265 b were the secondary-host morphs of T. chinensis. In this paper the secondary host morph of T. chinensis is described for the first time. With the identification of more species＇ secondary-host morphs, aphids identification based on this morph will be made easily.     

2014年全球新药研发报告——第二部分：趋势和挑战（Ⅳ）

2014 年制药和生物技术行业继续保持着高活力。截至2014 年12 月23 日,全球共有55 个新的化学药物和生物制品首次进入市场, 另有29 个重要的延伸性新药获批,还有19 个药物首次获批,但尚未来得及上市。此外,在传统的年底冲刺期间,一些国家的监管机构在 年底最后一刻还批准了其他一些药物,因此,这些获批药物未能被收录在内,所以2014 年实际获批的新药数量应该大于前面提到的数字。 除了新药的成功开发、注册和上市外,还有其他一些可反映整个行业现状和发展趋势的风向标,例如,监管机构采取新措施以刺激难治性 疾病药物的开发、制药公司定期并务实地对其研发项目进行甄选以及通过并购整合研发管线、投资项目和销售队伍。     

Aggregation and mating success of Capnodis tenebrionis （Coleoptera： Buprestidae）

An understanding of the relative importance of extrinsic and intrinsic factors in determining the potential distribution and mating success of individuals is critical for the successful monitoring and management of pest species. Using a combination of field observations and a caged field experiment, we explored the roles of environmental and individual variation on the formation of mating aggregations and mating success in the buprestid beetle Capnodis tenebrionis （Linnaeus, 1767）, a pest species of stone fruit trees. Our field observations revealed that the formation of aggregations is influenced by a range of environmental factors including temperature, photoperiod, and population density. However, aggregations were not at random and were more likely to occur on the section of the plant with highest incidence of solar radiation and thus higher temperatures. Data from our experiment with caged beetles in the field further indicate that the reproductive behavior of this species varies with temperature. The probability of a successful mating occurring was also positively related to both male and female size. Females of C. tenebrionis mate several times over a 4-h period, but generally not with the same male. Information obtained from these studies is useful to define the most appropriate time for pest control, especially adopting strategies that interfere with reproduction.     

Water Striders： The Biomechanics of Water Locomotion and Functional Morphology of the Hydrophobic Surface （Insecta： Hemiptera-Heteroptera）

Water striders are insects living on the water surface, over which they can move very quickly and rarely get wetted. We measured the force of free walking in water striders, using a hair attached to their backs and a 3D strain gauge. The error was calculated by comparing force and data derived from geometry and was estimated as 13%. Females on average were stronger （1.32 mN） than males （0.87 mN）, however, the ratio of force to weight was not significantly different. Compared with other lighter species, Aquarius paludum seems stronger, but the ratio of force to weight is actually lower. A. paludum applies about 0.3 mN.cm^-1 to 0.4 mN.cm 1 with its mid-legs, thus avoiding penetrating the surface tension layer while propelling itself rapidly over the water surface. We also investigated the external morphology with SEM. The body is covered by effectively two layers of macro-and micro-hairs, which renders them hydrophobic. The setae are long （40 μm-60μm） and stiff, being responsible for waterproofing, and the microtrichia are much smaller （〈10μm）, slender, and flexible, holding a bubble over the body when submerged.
