Phylogeny and morphology of Nemalionopsis shawii (Thoreales,Rhodophyta), a new generic record from mainland China

The freshwater red alga Nemalionopsis shawii Skuja is first reported for mainland China from specimens collected in Guangdong and Yunnan Province. Morphological observations and molecular sequences of rbcL and cox1 genes were used to identify and analyze the phylogenetic position of the samples. Samples from China formed a monophyletic clade with other N. shawii samples from Japan, Indonesia, and Nepal with robust support values. The pairwise genetic distances for N. shawii between the samples from China and other samples were 0.2–1.5% and 1.0–2.4% for rbcL and cox1, respectively. Both male and female reproductive structures were observed in the specimens from Guangdong, but only monosporangia in the specimen from Yunnan. The samples from China increase the diversity of morphological measurements for N. shawii. The discovery of this genus in mainland China results in a new record of a freshwater red alga for this country.     

First record of Isocapnia (Plecoptera: Capniidae) from China with description of a new species

Summary

The winter stonefly genus Isocapnia Banks, 1938??? is mainly distributed in western North America and eastern Asia, but has never been reported from China. In this paper, we report, describe and illustrate a new species of this genus, I. anguis n. sp. from Sichuan Province of China. This is the first record for the genus Isocapnia from China, extending the distribution of Isocapnia into the southwestern China. An identification key to all the Isocapnia species from Asia is provided.???     

The Aphelocheirid Bugs of China (Heteroptera: Aphelocheiridae)

A total of 14 species of genus Aphelocheirus Westw. from China are listed in this paper. One new species, Aphelocheirus brunneus sp. n., is described from Hubei Province. Aphelocheirus carinatus (Royer, 1920) is reported from China for the first time. The type specimens are deposited in the Department of Biology, Nankai University, Tianjin (300071), China.     

Demographic expansion and genetic load of the halophyte model plant Eutrema salsugineum

The halophyte model plant Eutrema salsugineum (Brassicaceae) disjunctly occurs in temperate to subarctic Asia and North America. This vast, yet extremely discontinuous distribution constitutes an ideal system to examine long‐distance dispersal and the ensuing accumulation of deleterious mutations as expected in expanding populations of selfing plants. In this study, we resequenced individuals from 23 populations across the range of E. salsugineum. Our population genomic data indicate that E. salsugineum migrated “out of the Altai region” at least three times to colonize northern China, northeast Russia and western China. It then expanded its distribution into North America independently from northeast Russia and northern China, respectively. The species colonized northern China around 33.7 thousand years ago (kya) and underwent a considerable expansion in range size approximately 7–8 kya. The western China lineage is likely a hybrid derivative of the northern China and Altai lineages, originating approximately 25–30 kya. Deleterious alleles accumulated in a stepwise manner from (a) Altai to northern China and North America and (b) Altai to northeast Russia and North America. In summary, E. salsugineum dispersed from Asia to North America and deleterious mutations accumulated in a stepwise manner during the expansion of the species’ distribution.     

新疆千里光Senecio jacobaea在中国的适生区预测

【背景】菊科植物新疆千里光原产于欧亚大陆,在北美和澳洲为入侵植物,目前在中国只有新疆有分布记录。新疆千里光一旦成为入侵植物,将对农业、畜牧业和人类健康都可能产生危害,所以需要评估其在中国的扩散趋势。【方法】搜集新疆千里光在中国和世界其他地区的分布记录,结合当前和未来(2050年)气候条件下19种生物气候变量,应用Maxent模型和Diva Gis软件,定量预测新疆千里光在中国目前和未来的潜在分布区域;并通过接受者操作特征曲线(ROC)分析法对模型进行精度检验。另外,通过Maxent给出新疆千里光在欧洲(原产地)、北美洲和大洋洲(入侵地)以及中国等4个分布区的年均温度和年均降水量的气候阈值。【结果】用中国和全球分布的数据预测的结果有些差异。前者结果表明除了新疆地区,其他省份几乎没有新疆千里光的适生区;而后者显示在中国其他几个省份也有可能分布,且在甘肃四川交界处有较高适生性。前者模型精确度较高,但2个结果都显示新疆千里光在中国目前和未来的分布区大部分还是在新疆地区。中国分布区年均温度和年均降水量的阈值比其他2个地区都低。【结论与意义】新疆千里光在当前和未来气候条件下在中国未来的扩散趋势较弱,基本局限于新疆地区。用中国分布数据预测优于全球分布数据预测结果,新疆千里光不同分布区的气候阈值的差异揭示分布于中国的新疆千里光与其他地区的种群的生态位有所不同,可能是一个新的亚种,希望未来能进行进一步的研究。

Mitochondrial DNA Distinction of Northeastern China Roe Deer, Siberian Roe Deer, and European Roe Deer, to Clarify the Taxonomic Status of Northeastern China Roe Deer

Partial sequences of the mitochondrial control region of northeastern China roe deer were analyzed to determine the degree of genetic diversity. Fourteen haplotypes were observed. The haplotype diversity was high (h = 0.872), nucleotide diversity was medium (p _i = 0.0108), and the average Tamura–Nei nucleotide distance among them was 1.9%, indicating that genetic diversity of roe deer from northeastern China was relatively high and that the effective population size was large historically. To clarify the northeastern China roe deer's taxonomic status, these 14 haplotypes were compared with 31 haplotypes published in Genbank from Europe, Siberia, and Korea. The average genetic distance between haplogroups of northeastern China and European roe deer (5.8%) was more than twice that between northeastern China and Siberian roe deer (2.7%), indicating sufficient variation to consider roe deer of northeastern China and Siberia as a single species (Capreolus pygargus), distinct from European roe deer (Capreolus capreolus). This is the first presentation of mtDNA data for roe deer in northeastern China, which will be helpful in investigations of genetic diversity and clarifications of the taxonomic status of roe deer in the whole of China.     

Yunotrechus diannanensis n. gen., n. sp., the first troglobitic trechine (Coleoptera: Carabidae) from a tropical area of China

In the present paper Yunotrechus diannanensis n. gen., n. sp. is described and illustrated from two limestone caves which are close to each other in Wenshan and Maguan counties of southern Yunnan Province, southwestern China. Yunotrechus is an anophthalmoid, not directly related to any hypogean trechine genera hitherto known in Yunnan or in southeastern Asian countries because all of them are aphaenopsoids, with elongated prothorax and tumid propleura. The phylogenetic position of Yunotrechus within Trechinae in China or southeastern Asia remains unclear, although it may be related to Superbotrechus Deuve & Tian 2009, which was recorded from western Hubei Province, central China, and Sichuanotrechus Deuve 2006, which was recorded from northern Sichuan Province, southwestern China. Y. diannanensis n. sp. is the first troglobitic trechine beetle discovered in a tropical area of China.
