新兴都邑赋与城市文化传承

新兴都邑赋具有传承城市文化的重要意义：以文学方式集中展演当代城市的群体形象，以延续或补白的方式传承城市文化遗产，以个体视角充分体现对当代城市的复杂感知，以发掘民族、地域文化彰显城市个性。中国当代城市化进程、有识之士的提倡与参与、赋体自身的文体特性是都邑赋复兴的综合成因。

一类单种群差分模型的混沌控制

针对一类具有物种流动时特定区域内的种群增长差分方程模型,采用数值模拟方法给出了Lyapunov指数随参数变化的图形,验证了混沌现象的存在.采取OGY参数微扰法进行混沌控制,使种群稳定到不动点和周期2轨道,消除了种群的混沌现象.仿真结果验证了控制的有效性.     

四合木花石油醚提取物的化学成分分析

以石油醚为溶剂,采用热回流法得到四合木花石油醚提取物,利用GC-MS联用技术分析鉴定其化学成分,共鉴定出24种化合物,其中烷烃类化合物10种、羧酸类化合物5种、酯类化合物3种、萜类化合物3种、甾体类化合物3种,共占样品总量的85.19%.四合木花石油醚提取物中相对含量最高的成分是Tetratetracontane（18.08%）,其次为Eicosane（15.77%）,再次是Nonacosane（13.43%）.这些化学成分的组成和含量在一定程度上反映了四合木对花期气候和分布区生态环境的适应性.     

Classical Biological Control of Bemisia tabaci in the United States. By Juli Gould,Kim Hoelmer & John Goolsby

ABSTRACT

The present study describes two new genera, six new species and three new records from the Sea of Marmara. The new genus Marmara gen. nov. belonging to the family Sagartiidae is mainly characterized by having conspicuous muscular belts along the column and the absence of suckers and tenaculi on the body wall. The genus Charisactis gen. nov. belonging to the family Condylanthidae is mainly characterized by having an atypical mesentery arrangement, single siphonoglyph and homotrichs in tentacles. The other species newly described from the Sea of Marmara belong to the families Diadumenidae (one species from deep waters), Halcampoididae (one species from shallow waters), Edwardsiidae (one species from shallow waters) and Epizoanthidae (one species from deep waters). Three species, namely Epizoanthus arenaceus (family Epizoanthidae), Rolandia coralloides (family Clavulariidae) and Virgularia sp. (family Virgulariidae) are reported for the first time from the Sea of Marmara. The external and internal anatomical features as well as cnidom structures of the species are presented and discussed with the closely related species. http://www.zoobank.org/urn:lsid:zoobank.org:pub:51DA9869-D786-4A8A-8C1F-62DC1BB67923

Stegana castanea species group (Diptera,Drosophilidae) from the Oriental region

The Stegana castanea species group is established as a morphological group within the subgenus Steganina, based on two known and six new species from the Oriental region: Stegana (Steganina) bacilla Chen and Aotsuka, 2004 Chen, HW and Aotsuka, T. 2004. A survey of the genus Stegana Meigen from southern Japan (Diptera, Drosophilidae). J Nat Hist., 38: 2779–2788.

Family Drosophilidae (Diptera) from the Lund University Ceylon Expedition in 1962 and Borneo collections in 1978–1979. Entomol Scand (suppl)., 30: 109–149.  [Google Scholar]; S. (S.) reni sp. nov.; S. (S.) tiani sp. nov.; S. (S.) tongi sp. nov.; S. (S.) wangi sp. nov., S. (S.) weiqiuzhangi sp. nov. and S. (S.) xui sp. nov. from southern China. A key to all the species of this group is provided.     

A new species of the pseudoscorpion genus Megachernes (Pseudoscorpiones: Chernetidae) associated with a threatened Sri Lankan rainforest rodent,with a review of host associations of Megachernes

Most species of the Old World pseudoscorpion genus Megachernes are associated with mammals, either within their nests or in their pelage, whereas others are found in cave systems, usually in bat guano. The first Sri Lankan species of the genus, Megachernes kanneliyensis, is described from the fur of an endemic, threatened Sri Lankan mouse, Mus mayori pococki from the Kanneliya rainforest. The species is compared with other species of the genus. Host associations of all named and several unnamed species of Megachernes are reviewed, with two main habitat types, those found in mammal nests and in their pelage, and those found in bat guano. Based on similarities with Megachernes, Chiridiochernes is transferred to Lamprochernetinae as the spermathecae are T-shaped, the sole diagnostic feature of the subfamily.
