福建省数种杯叶科吸虫研究及一新属三新种的叙述(鸮形目:杯叶科)

杯叶科是食鱼的爬行类、鸟类、哺乳类寄生的吸虫。本文修订了以往在福建报道的虫种,叙述了一个新属三个新种,取消了前此所定的一个属及种[Tangiella parovipara(Faust and Tang,1938)],认为是存疑的种。本文还报道了盖前冠吸虫 Prosostephanus Tubangu,1922的终末宿主河獭,从而作者(Tang,1941)完成了其生活史的研究。本文比较了从河獭所得的标本与从描、犬所获标本各器官的测量数据,发现由最佳的终末宿住所得标本,其个体及各器官和卵子的测量数据均较大。

Interspecific relations of African crocidurine shrews (Mammalia: Soricidae) based on multivariate analysis of mandibular data

Eighteen graded non-metric characters and 30 measurements of the mandible and lower dentition were used to investigate the grouping of African species of the genera Crocidura, Suncus and Sylvisorex. Seventy-seven taxa (species, subspecies and synonyms), including four European species, were represented by one to nine mandibles (147 mandibles in all), and the means of four Pleistocene African species were also included. The metric data were subjected to principal component and canonical variate analyses, and the non-metric data to principal component analysis. Grouping was detected by comparing the results of the three analyses. Six groups are recognized within the genus Crocidura , typified by C. fumosa, C. turba, C. russula, C. fuscomurina, C. hirta and C. flavescens. Sylvisorex is divisible into two groups, typified by S. lunaris and S. granti. The African species of Suncus (but not the introduced species, S. murinus ) form a single group, which is linked to the Sylvisorex granti group. Suncus is closely related to, or convergent with, the Crocidura fuscomurina group. The first non-metric principal component, the second metric principal component and the second canonical variate are significantly correlated. It is considered that these together represent a general trend of evolutionary advance. Phylogenetic relations are discussed in the light of this; Crocidura may be diphylefic.     

Uptake of volatilen-alkanes byPseudomonas PG-I

Using a bacterial speciesPseudomonas PG-1, evidence has been obtained which indicates that uptake ofn-pentane ton-octane by microbial cells takes place primarily from the gas phase either directly orvia the aqueous phase. Specific growth rate increased along with the increase in substrate concentration but above the alkane concentration of 0.3% by volume, specific growth rate decreased indicating substrate inhibition of growth. In the case of less volatile alkanes,n-nonane andn-decane, substrate transfer is predominantly through substrate solubilization system elaborated by the cells. EDTA, a strong inhibitor of hydrocarbon solubilization by the cells, inhibited growth on these two alkanes but had negligible effect on growth onn-pentane ton-octane.

农业生态系统中新物种引进的初步探讨

在现有的农业生态系统中,引进某些新物种,往往可以使整个系统的功能发生变化。如果新物种引进得当,则可产生良好的效果,系统功能得以改善,效益提高;反之,则会造成人力、物力、财力的损失,削弱系统的功能,甚至可能遗患无穷。因此,对农业生态系统中
