云南茶树上的附生地衣

对云南茶叶农场中的附生地衣进行调查发现: 附生在茶树上的地衣有25 属, 51 种; 其中, 45 种是首次报道附生在茶树上, 包括2 个中国新记录种: 癞屑衣( Lepraria lobificans) 和阿曼原胚衣( Protoblastenia amagiensis) , 以及20 个云南新分布种。壳状地衣的共生菌丝侵入茶叶树干外皮层组织, 在生长过程中产生地衣酸, 一定程度的加速了农场中茶树的老化; 靠近茶树发芽点生长的壳状地衣和叶状地衣, 造成芽体发育不良, 对茶叶的产量和品质有一定影响。

A latest Ordovician Hirnantia brachiopod fauna from western Yunnan,Southwest China and its paleobiogeographic significance

A new, high-diversity, latest Ordovician brachiopod fauna of nearly 800 brachiopod specimens was collected from the Wanyaoshu Formation (Hirnantian) in the Shaodihe section, Mangshi City, western Yunnan, Southwest China. Altogether 22 genera and two undetermined taxa were identified; dominant are Aegiromena, Anisopleurella, Fardenia, Dalmanella, Hirnantia and Hindella, less common, Paromalomena, Leptaena, Eostropheodonta, Cliftonia, Kinnella, Templeella and Plectothyrella, together with some rare Petrocrania, Xenocrania, Pseudopholidops, Palaeoleptostrophia, Skenidioides, Giraldibella, Draborthis, Dolerorthis and Toxorthis. This is one of the most diverse typical Hirnantia faunas, associated with the Kosov Province. The paleobiogeographic relationships between western Yunnan (Southwest China), Myanmar, Yichang (Central China), Tibet (Southwest China) and Kazakhstan are clarified using Network Analysis and NMDS. The fauna studied is most similar to that of Myanmar; both resided on the Sibumasu terrane. However, the recalculated network diagram, when including the data of Hirnantia fauna from the Prague Basin, indicates that the latter is more closely linked to that of western Yunnan, a testament to the very weak brachiopod provincialism during the Hirnantian, mainly due to the influence of dominant cosmopolitan taxa. Some species of the fauna display significant population variation. Two of the dominant taxa, Aegiromena and Anisopleurella are systematically described, whereas the other two common taxa, Fardenia and Hirnantia are measured and their outlines and internal structures analyzed.

云南南涧凤凰山秋季迁移鸟迁移时序与数量变化

2002年9月16日—11月28日和2003年9月9日—11月26日,在云南南涧凤凰山共网捕秋季迁移鸟176种6677只,分属13目29科。凤凰山鸟类夜间迁移时间开始于8月上旬,至11月中旬结束,可分为开始期、高峰期和结束期。高峰期出现于9月中旬—10月上旬,迁移波峰出现在10月初;高峰期间受圆月影响,中间出现2个网捕低谷。候鸟夜间迁移在日落后约1小时开始,在20:30—24:00出现第1个迁移高峰;随后鸟类迁移数量逐渐减少;到次日4:00左右又开始增多,出现当夜的第2个高峰;在凌晨5:30左右再度减少直到日出前为止。白天迁移主要出现在迁移后期,开始于10月中旬左右,10月下旬、11月中旬达到白天迁移高峰,随后逐渐减少,一直持续到11月下旬,1甚至到12月上旬。白昼迁移鸟在日出前约1小时开始迁过,8:30左右达到白昼迁移高峰,11:00后停止。凤凰山秋季迁移鸟的迁徙期持续约100天。夜间迁徙鸟在西南风无月有雾之夜在22:00过境高峰后,还会在午夜、凌晨和黎明前出现另外3个过境高峰,而其他天气仅在22:00出现1次过境高峰。     

Distribution of gamasid mites on small mammals in Yunnan Province, China

An investigation of gamasid mites on the body surface of small mammals was carried out in Yunnan Province of China from 1990 to 2004. The small mammal hosts were captured from 25 counties which represent five geographical subregions, namely Middle Subregion of Hengduan Mountains, Southern Subregion of Hengduan Mountains, Eastern Plateau Subregion of Yunnan, Western Plateau Subregion of Yunnan and Southern Moun- tainous Subregion of Yunnan. The captured 10 803 small mammal hosts belong to nine families, 29 genera and 52 species in four orders （Rodentia, Insectivora, Scandentia and Lagomorpha）. A total of 68 571 gamasid mites were collected from the body surface of the captured small mammal hosts and all the gamasid mites were identified to 10 families, 33 genera and 112 species. This paper lists all the mite species, together with their taxonomic position （genera and families） and their corresponding hosts. Much more mite species were found in the Middle Subregion of Hengduan Mountains than in other geographical subregions. The total individuals of mites and small mammals in the Middle Subregion of Hengduan Mountains are also the most plentiful in the five geographical subregions. Three dominant mite species and three dominant small mammal hosts were determined as the dominant species in the investigated areas of Yunnan Province. The dominant hosts are Rattus flavipectus （which accounts for 34.85% of the total individuals）, Apodemus chevrieri （13.43%） and Rattus norvegicus （10.40%） while the dominant gamasid mite species are Laelaps nuttalli （Hirst, 1915） （27.84%）, Laelaps echidninus （Berlese, 1887） （18.38%） and Laelaps guizhouensis （Gu et Wang, 1981） （14.79%）. The results showed the high species diversity of gamasid mites in Yunnan Province and the uneven distribution feature in different subregions.     

Neogene Flora of Tengchong Basin in Western Yunnan,China

The specimens were collected by our expedition from the Neogene flora of Tengchong basin, i.e. 20 families, 29 genera and 35 species, four of which are described as new species, its show with characteristics as follows: 1. Tengehong basin flora developed from the Paleogene flora of Tethys sea and remains some eharaeters of the latter, for example, containing forest forms of Fagaeeae and Lauraeeae with evergreen boradleaves. Since Late Miocene the Himalayas uplifted, the Tecthys sea was recessive from the region, and this region had started aequiring its present day configuration. The climate became arid and cool. The flora was expanded with some deciduous elements. 2. The flora was expanded with Leguminosae elements which may indicate the climate changing to arid. The age of the flora is considered to Late Miocene- Early Plioeene. Its elements closely resemble with the modern ones of Yunnan flora.     

云南石林碳酸盐岩表面气生蓝藻(蓝细菌)研究

云南石林的黑石头及其颜色会随着天气的变化而变化的自然景观,是由于其碳酸盐岩表面长满黑色气生蓝藻（蓝细菌）之故。经鉴定,气生蓝藻共４目,１１科,３１届,１８８种。种类十分丰富。其优势种主要为寄生微囊藻、红色星球藻、伯氏伪枝藻和皮壳伪枝藻等;寄生微囊藻和红色星球藻呈面状分布,相对均衡,伯氏伪枝藻和皮壳伪枝藻呈点状分布,相对集中。这些气生蓝藻的胶被色泽鲜艳,宽厚而坚硬,是适宜高山岩石表面生活的典型进化特征。在野外肉限观察时,气生蓝藻还表现出不同形态的微群落;发现气生蓝藻能溶解石灰石,形成钻孔,加速岩石的溶蚀与风化。这些现象表明,气生蓝藻与云南石林岩石表面的微形态及整个石林景观的形成都有着十分密切的关系。     

First Thyreophoran Type Tracks from the Middle Jurassic Chuanjie Formation of Yunnan Province,China

Two tridactyl footprints from the Chuanjie Formation (Middle Jurassic) of Yunnan Province, China are morphological characteristics of thyreophoran tracks. They show some similarities to Shenmuichnus, known from the Early Jurassic strata of both Shaanxi and Yunnan provinces, but are somewhat larger, thereby resembling the ichnogenus Stegopodus. Based on their general morphology and size being congruent with this ichnogenus, they are tentatively assigned here to cf. Stegopodus. This is the fourth report of large ornithischian (probably thyreophoran) tracks from the Lower-Middle Jurassic of China that indicates relatively large trackmakers that were likely to be taxonomically distinct from much smaller and gracile Anomoepus trackmakers, also of ornithischian affinity. The larger tracks indicate a hitherto unreported abundance, size range and diversity of track types attributed to this group. The parallel orientation of the two best preserved trackways may indicate gregariousness.
