十二种地卷目地衣固氮活性的种间差异

地卷目地衣是对许多生态系统的氮素循环具有重要影响的固氮类群,但其固氮活性的种间差异研究甚少。将不同产地和不同馆藏时间的12种地卷目地衣于相同条件下培养,即：亚石胶衣Collema subflaccidum、亚黑胶衣C. subnigrescens、坚韧胶衣C. tenax、裸果猫耳衣Leptogium hildenbrandii、猫耳衣L. menziesii、柄猫耳衣L. pedicellatum、土星猫耳衣L. saturninum、黑猫耳衣L. trichophorum、犬地卷Peltigera canina、分指地卷P. didactyla、裂芽地卷P. praetextata和地卷P. rufescens。以乙炔还原法（acetylene reduction assay）于培养1d、10d和15d测定其固氮活性,结果显示所有地衣的固氮活性在培养10d与15d之间差异不显著,表明经过至多10d的培养后地衣固氮活性即可完全恢复;培养10d和15d的固氮活性平均值表现出显著的种间差异（P＜0.001）：黑猫耳衣Leptogium trichophorum固氮活性最高[（4.532±0.368）μmol C2H4/gdw·h],约为犬地卷Peltigera canina的2倍[（2.349±0.223）μmol C2H4/gdw·h];其他10种地衣固氮活性大致相近。显示地衣固氮作用的可塑性较大,是地衣具有较强适应能力的又一例证。

A Preliminary Study on the Floristic Features of the Genus Burmannia in China

The genus Burmannaia is one of the largest genera in the Burmanniaceae, of which 12 species have been recorded in China. It is mainly a tropical genus. The species in China are all confined to the region south of Yangtze River. They are distributed chiefly in the provinces Guangdong (9 species) and Yunnan (6 species). After having studied the areas of all the species in China, we are able to classify them into following 4 area-types: 1. Area-type of Tropical Asia to Tropical Australia. The two non-saprophytic species (Burmannia disticha, B. caelestis) and one saprophytic (B. championii) belong to this area-type. It is an ancient type. The plants of this type mostly have a wide ecological amplitude, for example, B. disticha may be found in tropical and subtropical regions. The plants occur not only in evergreen forests, in bushs, but also in rather arid herbosa and on the side of streams (Fig. 2). 2. Area-type of Tropical SE Asia. In the type are 3 saprophytic species i.e. B. oblonga, B. wallichii and B. nepalensis. 3. Area-type of E. Asia. (Fig. 3) Burmannia in China with E. Asian distribution is poor in species. There are only 2 saprophytic species. B. cryptopetala is distri-buted in Haina (China), Kyushu and Honshu (Japan); B. itoana occurs in Taiwan (China), Riukiu and Kyushu (Japan). They are known only on the islands of E. Asia. Such a pattern of distribution may suggest connection of these islands once in the prehistoric time in spite of their present isolation. 4. Endemic area-type. (Fig. 4). Here are 3 saprophytic species and one variety with green leaves. B. nana occurs only in E. Taiwan. One of the two new species described by present author in this paper, B. fadouensis, is known from Xichou Xiao, S. E. Yunnan, to Longzhou Xian of the province Gaunxi; the other one, B. pingbienensis occurs only in Pinbien Xian of S. E. Yunnan. The last species is endemic to China. B. pusilla var. hongkongensis is non-saprophytic and known from the province Guangdong and its bordering islands. Both B. fadouensis and B. pingbienensis are characterized by the axillary bulbils, which enable them to adapt to rather arid and cold condi-tions in northern part of the tropical region.     

Cryptic bumblebee species: consequences for conservation and the trade in greenhouse pollinators

Commercial greenhouse growers in both Japan and China are increasingly using reared orange-tailed bumblebees known previously as Bombus hypocrita Pérez as pollinators. Phylogenetic analysis of the DNA (COI) barcodes with Bayesian methods shows that this "species" is a long-standing confusion of two cryptic species. We find that the orange-tailed bumblebees in North China are actually part of the widespread Russian (otherwise white-tailed) B. patagiatus Nylander (as B. patagiatus ganjsuensis Skorikov, n. comb.), whereas the orange-tailed bees in Japan are true B. hypocrita. This situation has been further complicated because two other cryptic species from North China that were previously confused with the Russian B. patagiatus are now recognised as separate: B. lantschouensis Vogt n. stat. and B. minshanensis Bischoff n. stat.. As demand for pollination services by greenhouse growers inevitably increases, these bees are more likely to be transported between countries. In order to conserve genetic resources of pollinator species for their option value for future food security, we advocate preventing trade and movement of B. patagiatus from China into Japan and of B. hypocrita from Japan into China.
