The prevalence of Hepatocystis kochi in African green monkeys.

The prevalence of Hepatocystis kochi was studied in 178 African green monkeys from Kenya and 61 from Ethiopia. Examinations of blood smears for gametocytes and examinations of the livers for merocysts were performed to determine the presence of infection in these animals. The overall prevalence of infection was 29%. No significant difference in infection rate was found between monkeys from the different geographic areas or between males and females.

云南白马雪山自然保护区猕猴和滇金丝猴的生态位分离(英文)

原则上,食叶的滇金丝猴(Rhinopithecus bieti)和杂食的猕猴(Macaca mulatta)是可以同地共栖的,但这两种灵长类究竟是如何同地共存却一直是一个鲜见涉足的问题。该文初步通过分析它们的食性和生境需求来阐明两者共存的可能性。在猕猴取食约22种植物中,有16种也是滇金丝猴的取食对象。两种灵长类都显示出喜食果实。人们尚未发现滇金丝猴涉足人类作物等相关资源,但发现猕猴经常侵食庄稼。这与其生活海拔不同有关:滇金丝猴一般生活在平均海拔为3218m的山林中,而猕猴活动在平均海拔为2995m的林地。猕猴也会涉足牧场,而滇金丝猴回避这种场地。对于这两个种,混合的落叶阔叶/针叶林是最频繁使用的森林类型;滇金丝猴很少进入常绿阔叶林(青冈属群落,利用率仅3%),而猕猴相对进入这类林型的机会远比滇金丝猴高(36%)。两个物种的群体间常相互远离(2.4km)。当其相遇时,常是猕猴主动回避。上述结果提示滇金丝猴和猕猴是通过大生境分化利用和空间避让来共存的。尽管不同的生境利用策略一定程度上会反映种间竞争的存在,但这种不同更可能反映着它们不同的生理/生态需求。     

Hoya tengchongensis sp. nov. (Apocynaceae,Asclepiadoideae) from Yunnan,China

Hoya tengchongensis, a new species of Apocynaceae, subfamily Asclepiadoideae from Yunnan, China, is described and illustrated. The new species is morphologically similar to Hoya serpens in its creeping habit, bearing small and suborbicular leaves, and adaxially tomentose corolla. However, H. tengchongensis differs from H. serpens in corolla size (ca 7 mm versus ca 12 mm in diam) and corona morphology (corona lobes slightly ascending versus erect).     

Pterygiella trichosepala (Orobanchaceae), sp. nov. from Yunnan,southwest China

Pterygiella trichosepala (Orobanchaceae) is described and illustrated as a new species endemic to Yunnan, southwest China. It grows in calcareous grasslands or scrubs at elevations of 2000–2600 m a.s.l. This new species is closely related to P. nigrescens Oliv., but clearly differs from the latter by being pilose–hirsute throughout, with stems simple or rarely branched, 10–30 cm tall, and leaves 10–20 mm long and 3–6 mm wide (with L/W ratio 3.5–5.0), racemose inflorescences, and calyx 13–20 mm long and 8–13 mm in diameter; moreover its seed micromorphological features are significantly different from those of P. nigrescens.     

Calanthe yaoshanensis sp. nov. (Orchidaceae) from northeastern Yunnan,China

A new species of Orchidaceae, Calanthe yaoshanensis Z. X. Ren & H. Wang from northeastern Yunnan, China, is described and illustrated. It is morphologically similar to C. brevicornu Lindley, from which it differs by having a glabrous column and an elliptical middle lobe with three triangular lamellae. The morphological differences between C. yaoshanensis and related species are discussed. The habitat was investigated and its conservation status was assessed as a ‘Critically Endangered’ (CR).     

Kineococcus glutineturens sp. nov., isolated from soil in Yunnan, south-west China

An orange-coloured, non-spore-forming, motile and coccus-shaped actinobacterium, designated YIM 75677^T, was isolated from a soil sample collected from a dry-hot river valley in Dongchuan county, Yunnan Province, south-west China and its taxonomic position was investigated. Growth of strain YIM 75677^T occurred at 12–55 °C, pH 6.0–9.0 and NaCl tolerance up to 2 % (w/v). Cells adhered to agar media and were agglutinated tightly together. The peptidoglycan contained meso-diaminopimelic acid, alanine and glutamic acid. The whole-cell hydrolysates mainly contained glucose, galactose, mannose and ribose. The predominant menaquinone was MK-9 (H₂) and the major fatty acids were anteiso-C_15:0 and iso-C_15:0. Mycolic acids were not present. The DNA G+C content of strain YIM 75677^T was 74.8 mol%. Phylogenetic analyses based on 16S rRNA gene sequence comparisons clearly revealed that strain YIM 75677^T represents a novel member of the genus Kineococcus and is closely related to Kineococcus xinjiangensis S2-20^T (level of similarity, 98.6 %). Meanwhile, the result of DNA–DNA hybridization between strain YIM 75677^T and K. xinjiangensis S2-20^T demonstrated that this isolate represented a different genomic species in the genus Kineococcus. On the basis of phylogenetic, phenotypic and chemotaxonomic characteristics, strain YIM 75677^T represents a novel species of the genus Kineococcus, for which the name Kineococcus glutineturens sp. nov. is proposed. The type strain is YIM 75677^T (=CCTCC AA 209075^T = JCM 18126^T).

Virological survey of rhesus monkeys in China

A virological survey of rhesus monkeys captured in China for 13 viruses and/or antibodies was performed. Antigens used were SFV, SF40, HSV-1, Sa11, measles, vaccinia, epidemic or simian hemorrhagic fever, Langat, Kunming, poliomyelitis, HIV, SV41 and rubella. Monkeys were from Sichuan, Hunan, Guizhou, Yunnan and Guangxi provinces. Antibody was detected to all the listed viruses except HIV, SV41 and rubella. Both SFV and SV40 were recovered from monkeys, but H. simiae, LCM and coxsackieviruses were not.
