Think ＂ Big＂ and become ＂ Big＂ ： On the architectureand space of an urban museum

Nowadays many urban museums are situated in ever-changing cities face with problems regardingspace and architecture. The main question this paper wants to discuss is how the museum could achieve accessibilityand inclusiveness to a greater extent via rethinking and reshaping its space, both physically and vir -tually,Based on practices conducted by the Museum of London since its establishment in the 20th century, Iendeavour to understand how the museum architecture was established during the negotiation and compro -mise among different individuals and parties and to extend the conception by exploring the possibilities of expanding out of the traditional realm of the museum architecture.

Effect of Two Substrate Types on Feeding Efficiency by Juvenile Chinese Sturgeon Acipenser sinensis on Barcheek Goby Rhinogobius giurinus

We conducted experiments in an artificial stream tank with wild juvenile Chinese sturgeon Acipenser sinensis captured in the Yangtze Estuary to test the null hypothesis that their feeding efficiency on Barcheek goby Rhinogobius giurinus was not affected by sand vs. smooth glass substrate. Gobies are among the most common prey eaten by wild juvenile A. sinensis in the estuary. Test results found neither substrate type significantly affected feeding efficiency by juveniles. Previous research found a strong innate habitat preference of A. sinensis for sand substrate. The present results indicate that the preference for sand is not related to efficiently capturing R. giurinus on sand, but is an adaptation predisposing juvenile A. sinensis to seek sandy substrate where R. giurinus and other benthic forage are the most abundant in the Yangtze Estuary.

Rhinogobius immaculatus, a new species of freshwater goby (Teleostei Gobiidae) from the Qiantang River, China

A new freshwater goby, Rhinogobius immaculatus sp. nov., is described here from the Qiantang River in China. It is distinguished from all congeners by the following combination of characters： second dorsal-fin rays I, 7-9; anal-fin rays I, 6-8; pectoral-fin rays 14-15; longitudinal scales 29-31; transverse scales 7-9; predorsal scales 2-5; vertebrae 27 （rarely 28）; preopercular canal absent or with two pores; a red oblique stripe below eye in males; branchiostegal membrane mostly reddish-orange, with 3-6 irregular discrete or connected red blotches on posterior branchiostegal membrane and lower operculum in males; caudal-fin base with a median black spot; and no black blotch on anterior part of first dorsal fin in males.

Genetic diversity and population structure of a Sichuan sika deer(Cervus sichuanicus) population in Tiebu Nature Reserve based on microsatellite variation

Cervus sichuanicus is a species of sika deer （Cervus nippon Group）. To date, research has mainly focused on quantity surveying and behavior studies, with genetic information on this species currently deficient. To provide scientific evidence to assist in the protection of this species, we collected Sichuan sika deer fecal samples from the Sichuan Tiebu Nature Reserve （TNR） and extracted DNA from those samples. Microsatellite loci of bovine were used for PCR amplification. After GeneScan, the genotype data were used to analyze the genetic diversity and population structure of the Sichuan sika deer in TNR. Results showed that the average expected heterozygosity of the Sichuan sika deer population in TNR was 0.562, equivalent to the average expected heterozygosity of endangered animals, such as Procapra przewalsldi. Furthermore, 8 of 9 microsatellite loci significantly deviated from the Hardy-Weinberg equilibrium and two groups existed within the Sichuan sika deer TNR population. This genetic structure may be caused by a group of Manchurian sika deer （Cervus hortulorum） released in TNR.

New species of Paratullbergia and Pongeiella(Collembola: Tullbergiidae) from northwest China

Two new species of Tullbergiidae, Paratullbergia qilianensis sp. nov. from Gansu and Pongeiella yinchuanensis sp. nov. from Ningxia, northwest China are described. Paratullbergia qilianensis is characterized by the presence of one pair of pseudocelli on thoracic segment Ⅰ, with two pairs of pseudocelli on each of thoracic segments Ⅱand Ⅲ, seta px present on abdominal segment Ⅳ, setae a2 and p4 on abdominal segment V as macrosetae, and a less differentiated sensillum p3 on abdominal segment Ⅴ.Pongeiella yinchuanensis is characterized by the pseudocelli of type Ⅲ, the presence of seta p3 on Th.Ⅱ and Ⅲ, five thickened sensilla on Ant.Ⅳ with four of them having distinct basal heels and seta oc2 on head as macroseta.
