Matsutake Trade in Yunnan Province,China: An Overview

Matsutake Trade in Yunnan Province, China: An Overview. Matsutake are economically important wild mushrooms that contribute greatly to rural livelihoods and local economies in many parts of the northern hemisphere. This paper provides an overview of the matsutake trade in Yunnan province, China, where increased attention is being given to the sustainable utilization of nontimber forest products. Topics covered include the distribution, production, and export of matsutake in Yunnan, and the market chain for matsutake in Yunnan, whereby matsutake are harvested from the wild and exported to Japan within 48 hours.     

云南菜食花植物资源与食花文化调查

为了摸清云南省菜食花植物资源种类、自然分布与食用地区、食用方法等土著知识,对云南省16个地州102个县(市)农贸市场、地方菜餐馆、民间食花者进行了访问调查,对菜食花植物进行了植物学实地鉴定。调查到云南省菜食花植物140种,隶属52科108属,其中木本植物82种,草本植物58种;人工栽培76种,人工驯化栽培14种,野生资源50种。首次报道苦绳(Dregea sinensis Hemsl.)、云南山楂(Crataegus scabrifolia(Franch.)Rehder)、滇海水仙花(Primula pseudodenticulata Pax)、长毛黄葵(Abelmoschus crinitus Wall.)、尖叶美容杜鹃(Rhododendron caloplytum var.openshawianum(Rehd.et Wils.)Chamb.)、大纽子花(Vallaris indecora(Baill.)Tsiang et P.T.Li)、大花虫豆(Cajanus grandiflorus(Benth.ex Baker)Maesen Vaniot der Maesen)、须弥葛(Pueraria wallichii DC.)、白花灯笼(Clerodendrum fortunatum L.)等9种植物的花可以做菜食用。菜食花植物自然分布区与食用地区并非完全重叠,食用地区一般分布有该植物,而分布有该植物的地区不一定食用;食用种类具有从南向北逐渐减少的特点,与食花植物丰富度和少数民族有一定的关系;食花习俗具有一定的民族性,主要体现食花的种类和烹饪口味上。不同菜食花食用的部位不同,烹饪方式也呈多样化。本文针对食用花传统文化的消失与野生菜食花资源的开发利用提出了相关建议。     

The Houses That Matsutake Built<Superscript>1</Superscript>

The Houses That Matsutake Built. In the mountains of northwest Yunnan, China, a valuable mushroom, matsutake or song rong (Tricholoma matsutake) was commodified in the 1980s. Since that time, it has been exported in large quantities to Japan. The sale of matsutake now contributes more to the income of Shangri-la County (Diqing Autonomous Tibetan Prefecture) than any other crop, including timber and livestock. During the 1980s and 1990s, villagers in this remote region used their mushroom earnings to build spacious, beautiful new houses in the traditional local (Kham) style, and in some cases to buy motor vehicles or open businesses. In villages with access to productive matsutake habitat, virtually every household was able to build a new house; entire villages were transformed. During the 1990s, several villages developed locally based management regimes to enhance production and to address the problems and conflicts that arose from the harvest of such a valuable product. More recently, government agencies and NGOs have played a highly visible role in promoting “sustainable” harvest policies. The implications of their involvement are briefly examined and the future of matsutake harvest in Yunnan is discussed.     

Chewing lice from high‐altitude and migrating birds in Yunnan,China, with descriptions of two new species of Guimaraesiella

In total, 366 birds representing 55 species in 24 families and eight orders, were examined for chewing lice (Phthiraptera: Amblycera, Ischnocera) in two high‐altitude localities in Yunnan Province, China. In Ailaoshan, almost all of the birds examined were resident passeriforms, of which 36% were parasitized by chewing lice. In Jinshanyakou, most birds were on migration, and included both passerine and non‐passerine birds. Of the passerine birds caught in Jinshanyakou, only one bird (0.7%) was parasitized by chewing lice. The prevalence of Myrsidea and Brueelia‐complex lice on birds caught in Ailaoshan was higher than in previous reports. Of the chewing lice identifiable to species level, three represent new records for China: Actornithophilus hoplopteri (Mjöberg, 1910), Maculinirmus ljosalfar Gustafsson & Bush, 2017 and Quadraceps sinensis Timmermann, 1954. In total, 17 new host records are included, of which we describe two as new species in the Brueelia‐complex: Guimaraesiella (Cicchinella) ailaoshanensis sp. nov. ex Schoeniparus dubius dubius (Hume, 1874) and G. (C.) montisodalis sp. nov. ex Fulvetta manipurensis tonkinensis Delacour & Jabouille, 1930.

中国云南高原鳅属洞穴盲鱼一新种——邱北盲高原鳅

2002年和2006年,在云南省邱北县腻脚村一喀斯特洞穴深处各采到一批盲鳅标本,经鉴定,为高原鳅属(Triplophysa)一未记录的新种--邱北盲高原鳅。新种具有的特殊头形及可数性状等特征,与中国已记录的穴居高原鳅均不同,而与分布于金沙江水系的前鳍高原鳅(T.anterodorsalis Cao et Zhu)相近,但新种有下列特征可与之相区别:1)无眼vs.眼正常;2)背鳍分枝鳍条7vs.8-9;3)尾叉形vs.尾微凹。新种与同水系(南盘江)的大斑高原鳅(T.macromaculata Yang)也较相近,但可与之相区别:1)无眼vs.有眼;2)无色素vs.有斑;3)尾叉形vs.尾微凹。

Abundances and host relationships of chigger mites in Yunnan Province,China

This paper reports on ectoparasitic chigger mites found on small mammals in Yunnan Province, southwest China. Data were accumulated from 19 investigation sites (counties) between 2001 and 2009. A total of 10 222 small mammal hosts were captured and identified; these represented 62 species, 34 genera and 11 families in five orders. From the body surfaces of these 10 222 hosts, a total of 92 990 chigger mites were collected and identified microscopically. These represented 224 species, 22 genera and three subfamilies in the family Trombiculidae (Trombidiformes). Small mammals were commonly found to be infested by chigger mites and most host species harboured several species of mite. The species diversity of chigger mites in Yunnan was much higher than diversities reported previously in other provinces of China and in other countries. A single species of rodent, Eothenomys miletus (Rodentia: Cricetidae), carried 111 species of chigger mite, thus demonstrating the highest species diversity and heaviest mite infestation of all recorded hosts. This diversity is exceptional compared with that of other ectoparasites. Of the total 224 mite species, 21 species accounted for 82.2% of all mites counted. Two species acting as major vectors for scrub typhus (tsutsugamushi disease), Leptotrombidium scutellare and Leptotrombidium deliense, were identified as the dominant mite species in this sample. In addition to these two major vectors, 12 potential or suspected vector species were found. Most species of chigger mite had a wide range of hosts and low host specificity. For example, L. scutellare parasitized 30 species of host. The low host specificity of chigger mites may increase their probability of encountering humans, as well as their transmission of scrub typhus among different hosts. Hierarchical clustering analysis showed that similarities between different chigger mite communities on the 18 main species of small mammal host did not accord with the taxonomic affinity of the hosts. This suggests that the distribution of chigger mites may be strongly influenced by the environment in which hosts live.     

云南丽江-大理地区现代表土花粉垂直分布特征

文章主要研究云南丽江-大理地区不同海拔高度表土花粉。虽然松属花粉在各个植被带都占有优势，但是建群种花粉含量相对较高。降趋对应分析法（detrended correspondenc eanalysis，简称DCA）分析显示，表土花粉的分布和海拔之间具有非常密切的关系，DCA第一轴的值和海拔高度之间的线性相关系数达0．82（r^2=0．82）。此次研究表明，在云南山地，可以通过含量相对较高的花粉来重建古植被。     

云南亚热带南部表土孢粉组合与植被间的定量关系

以云南亚热带南部沿温度带分布的35个表土孢粉样品和7个植被样方调查为基础，计算了代表性孢粉类型的百分比和孢粉浓度，及常见孢粉的R值，并分析了影响R值的因素；同时，研究了植物群落和样方内孢粉组合的相似度。结果表明，云南亚热带南部表土样品孢粉产量丰富，蕨类植物孢子产量较高，具有典型的亚热带特征，且山地垂直分异显著；木本、草本植物花粉基本代表了区域内乔木和草本植物特征，蕨类植物孢子则具有超代表性；表土孢粉组合与植物群落间的相似系数绝大部分都在70％以上，表土孢粉组合基本上可以反映植物群落面貌；表明云南亚热带地区表土孢粉与现代植被之间具有较好的对应关系，这对在该区利用化石孢粉资料定量恢复古植被和重建古气候有重要意义。
