Ultrastructure of Spermatozoa of Eumeces elegans

The sperm ultrastructure of E.elegans is similar to that of the species within the Sphenomorphus and the Egernia groups, but evidence of spermatozoal autapomorphies is not found in E. elegans.

Ontogenetic Changes of Sexual Dimorphism in Head Size and Food Habit in Grass Lizard,Takydromus septentrionalis

It is supported that sexual selection is the main evolutionary source of smaller heads in female T.septentrionalis and that no direct evidence shows a substantial contribution of the divergence in head size to the segregation of food niche between males and females.

The comparative study on the macrobenthic community ecology between the mangrove swamp and the naked tidal flat at the Yueqing Bay

The biodiversity indexes(S H′) and the Pielou index of the mangrove swamp were highest, the Simpson index was the lowest at three kind of habitat types, it maybe relate to the habitat complication at mangroves swamp.

Morphological variations and discriminant analysis of different geographical populations of Tegillarca granosa

Based on nine morphological characters of populations of Tegillarca granosa from Guangxi, Zhejiang, Shandong,of China and Lishui, Korea, multivariate morphometrics was used to investigate their…

The isozymes in different populations of clam Meretrix meretrix

No significant differences in the isozymes phenotypes in SOD,AMY,CAT,ME, and MDH was observed between populations of S and G, but EST demonstrated a significantly different at isozyme phenotypes between S andG, showing distinct specific of geographical population.

A New Species and A New Record of Freshwater leeches From China (Arhynchobdellida:Salifidae)

The description of a new species named Barbronia yunnanensis sp.nov.and the diagnosis of Salifa lateroculata (Kaburaki,1921) which is a new record in China is gaves.

Inter-population Differences in Reproductive Life-history Traits of Blue-tailed Skinks ( Eumeces elegans ) from Hangzhou and Ningde, Eastern China

In E. elegans, reproductive life histories differ significantly between the two populations, and maternal body size accounts for a large quantity of such inter-population differences, suggesting that the reproductive strategies for this species change from a high-latitudinal population to a low- latitudinal population.

ULTRASTRUCTURAL STUDIES ON SPERMIOGENESIS OF TAKYDROMUS SEPTENTRIONALIS

It has great significance of nucleus and cell organelle as taxonomic character of Squamate lizard in the ultrastructure of spermiogenesis of Takydromus septentrionalis.

Karyotypes Analysis of Different Geographical Populations in the Chinese Skink ( Eumeces chinensis)

It was demonstrated that Eumeces chinensis from the four different geographicl populations have 2n=26=18m+4sm+4t, NF=48, and the second chromosome (2q) was the SAT-chromosome.

Study on community structure of invertebrates in rocky intertidal zone of Beiji Islands

The community types and structures of invertebrates of Beiji Islands were investigated from July 1997 to April 1998. The Shannon-Wiener diversity index (H′), Pielous species uniform index (J),…
