Abstract. We evaluated the taxonomic status of specimens representing two listed rare species of Pannaria in the Pacific Northwest, P. rubiginosa and P. rubiginella, based on DNA sequences of recently collected samples. We combined those data with new sequences for other Pannaria species in North America and South America as well as all available sequences from the P. rubiginosa and P. lurida groups plus closely related P. hookeri, based on results from initial analyses. Historically, P. rubiginosa and P. rubiginella have been separated in the Pacific Northwest based on the paraphenylenediamine (P) reaction of the cortex versus the medulla. Phylogenetic reconstruction based on ITS sequences demonstrated that both chemotypes belong to a single well-supported clade, and that it belongs to neither P. rubiginosa nor P. rubiginella. Instead, the Pacific Northwest material appears to belong to an undescribed species very similar morphologically to P. rubiginosa, but genetically and geographically distinct from that species and with smaller spores. We describe this new species as Pannaria oregonensis, assigning all of the material from the Pacific Northwest to this taxon, regardless of the location of the P+ reaction. This conclusion is supported by phylogenetic analysis of co-occurring populations of different chemotypes. We recommend removing P. rubiginella from the North American checklist. We also provide a revised key to the North American species of Pannaria, based on our current understanding. Furthermore, based on new sampling of Pannaria species from North and South America, we show a need for revision of the isidiate species of Pannaria, in particular P. tavaresii in the broad sense.
摘要根据最近收集的样本的DNA序列,我们评估了太平洋西北部两个被列入名录的罕见Pannaria物种——P.rubiginosa和P.rubijinella的标本的分类地位。根据初步分析的结果,我们将这些数据与北美和南美洲其他Pannaria物种的新序列,以及来自P.rubiginosa和P.lurida群以及密切相关的P.hookeri的所有可用序列相结合。从历史上看,根据皮质与髓质的对苯二胺(P)反应,P.rubiginosa和P.rubijinella在太平洋西北部被分离。基于ITS序列的系统发育重建表明,这两种化学型都属于一个支持良好的分支,既不属于P.rubiginosa也不属于P.rubiginella。相反,太平洋西北部的物质似乎属于一个未描述的物种,在形态上与P.rubiginosa非常相似,但在基因和地理上与该物种不同,孢子较小。我们将这个新物种描述为Pannaria oregonensis,将太平洋西北部的所有物质都分配给这个分类单元,而不考虑P+反应的位置。这一结论得到了不同化学型共存种群系统发育分析的支持。我们建议将P.rubiginella从北美清单中删除。根据我们目前的了解,我们还提供了一个修订后的Pannaria北美物种的密钥。此外,基于对北美洲和南美洲Pannaria物种的新采样,我们表明有必要对Pannaria的中间物种,特别是广义的P.tavaresii进行修订。

Abstract. Sciaromiopsis comprises a single species, S. sinensis, endemic to China. The genus is currently placed in the Amblystegiaceae, solely on the basis of gametophytic characters since its sporophytes are unknown. As a semiaquatic plant, the character of a strong leaf costa and marginal borders can aid S. sinensis to adapt drought as while as aquatic conditions. In this study, the phylogenetic position of Sciaromiopsis was revisited based on morphological and molecular phylogentic evidences of three datasets, the plastid rps4 dataset with 346 mosses species, the ITS dataset with 104 moss species and 82 plastid protein-coding gene dataset with 32 moss species. According to the morphological characters of gametophyte, the stable pattern of pseudoparaphyllia, leaf cells smooth and single costa of Sciaromiopsis are consistent with key characteristics of the Brachytheciaceae, the ovate-lanceolate leaves, differentiated alar cells and rhomboidal median leaf cells are consistent with key characteristics of the Brachythecium. Maximum likelihood and Bayesian analyses of both datasets of the rps4 gene and the 82 plastid protein-coding genes clearly indicated that Sciaromiopsis is a member of Brachytheciaceae. Sciaromiopsis sinensis is either clustered in a well supported clade among species of Brachythecium, Koponeniella and Myuroclada in the rps4 tree, or strongly supported as the sister to Brachythecium rivulare in plastid 82 gene tree. Maximum likelihood analysis of the nuclear ITS locus suggested that S. sinensis is nested within Brachythecium with moderate support. Thus, S. sinensis should be considered as a member of the Brachythecium, the diagnostic character of its leaf margin bordered by 5–8 rows of linear cells making it an easy distinction from other species of Brachythecium.
摘要Sciaromiopsis包括一种,S. sinensis,中国特有。由于其孢子体尚不清楚,因此目前仅根据配子体特征将其归入无孢子菌科。作为一种半水生植物,强叶缘和边缘缘的特征有助于紫荆适应干旱和水生环境。本研究基于346种苔藓质体rps4数据集、104种苔藓质体ITS数据集和32种苔藓质体蛋白编码基因数据集3个数据集的形态和分子系统发育证据,重新审视了香体藓属的系统发育位置。从配子体的形态特征来看,剑齿苋的假葡萄叶形态稳定、叶细胞光滑、叶脉单一等特征与短叶子科的关键特征相一致,卵形披针形叶、分化的翼细胞和菱形中间叶细胞与短叶子科的关键特征相一致。rps4基因和82个质体蛋白编码基因的最大似然分析和贝叶斯分析表明,Sciaromiopsis属短叶蝉科。在rps4基因树中,中华Sciaromiopsis可能与Brachythecium、Koponeniella和Myuroclada属于一个支持良好的分支,或者在plastid 82基因树中,中华Sciaromiopsis与Brachythecium rivulare为姊妹分支。核ITS基因座的最大似然分析表明,中华沙棘在短叶鞘内嵌套,支持度适中。因此,sinensis应该被认为是短枝属植物的一个成员,其叶缘以5-8行线状细胞为界的诊断特征使其易于与其他短枝属植物区分。

Taxonomic reevaluation of the Japanese Marchantia taxa belonging to sect. Papillatae of subg. Chlamidium (Marchantiaceae) 日本Marchantia分类群的分类学再评价。亚属的Papillatae。Chlamidium(马钱科)

Abstract. The Japanese Marchantia taxa belonging to sect. Papillatae of subg. Chlamidium have been taxonomically ambiguous for a long time because many species and infraspecific taxa have been described based on their broad morphological variation. In order to resolve this taxonomic problem, nearly 200 specimens including type material of names placed in the section were morphologically examined. Among them, 45 specimens collected during our recent field work in Japan were newly sequenced for phylogenetic analysis. The molecular analysis showed that Japanese plants belonging to sect. Papillatae should be partitioned into two distinct clades. The plants belonging to the two clades were distinguishable by the presence or absence of a dark median band on the thallus and the morphology of the appendage of ventral scales and gametangiophores. Geographic distribution and ecological habitats in Japan also support the partitioning into two distinct clades. We propose the new combination M. emarginata subsp. cuneiloba (≡ M. cuneiloba). We also suggest that M. emarginata subsp. cuneiloba and M. papillata subsp. grossibarba are the appropriate names for the plants belonging to each clade. The species previously described from Japan (e.g., M. radiata Horik., M. tosana Steph. and M. tosayamensis Steph.) were synonymized for both of them.
摘要日本Marchantia分类群属于门。亚属的Papillatae。长期以来,Chlamidium在分类学上一直不明确,因为许多物种和种下分类群都是基于其广泛的形态变异来描述的。为了解决这个分类学问题,对近200个标本进行了形态学检查,其中包括放置在切片中的名称的模式材料。其中,我们最近在日本实地工作期间收集的45个标本被新测序用于系统发育分析。分子分析表明,日本植物属于门。Papillatae应该分为两个不同的分支。属于这两个分支的植物可以通过铊上是否存在深色中间带以及腹侧鳞片和配子血管载体附属物的形态来区分。日本的地理分布和生态栖息地也支持将其划分为两个不同的分支。我们提出了新的组合M.emarginata subsp。cuneiloba。我们还认为,M.emarginata subsp。cuneiloba和乳头分枝杆菌亚种。grossibarba是属于每个分支的植物的合适名称。先前从日本描述的物种(例如M.radiata Horik、M.tosana Stephen和M.tosayamensis Stephen)是它们的同义词。

Abstract. Sarcogyne similis is found to produce psoromic acid, a substance previously known from only one other species in the family Acarosporaceae. Study of more than one hundred specimens from throughout the range of S. similis confirms the species is widely distributed from Nova Scotia, Canada, south throughout much of the eastern United States, and westward through the Sonoran Desert to southern California, where it occurs on non-calcareous rocks, especially sandstone. The recently proposed synonymy with S. reebiae is confirmed. Sarcogyne similis f. convexa is lectotypified with material that contains psoromic acid. The type of S. californica, currently treated as a synonym of S. similis, does not produce psoromic acid and may belong to a separate taxon. The distribution of S. dakotensis, which produces norstictic acid, appears to be nearly allopatric with S. similis.
摘要Sarcogyne similis被发现能产生补骨脂酸,这种物质以前只从Acarosporaceae的其他一个物种中已知。对来自整个类似S.similis地区的100多个标本的研究证实,该物种广泛分布于加拿大新斯科舍省、美国东部大部分地区以南、向西穿过索诺兰沙漠到加利福尼亚州南部,在那里它出现在非钙质岩石上,尤其是砂岩上。最近提出的与S.reebiae的同义词得到了证实。用含有补骨脂酸的材料对类似于康氏肉瘤的Sarcogyne进行了筛选。加利福尼亚S.californica的类型,目前被视为类似S.similis的同义词,不产生补骨脂酸,可能属于一个单独的分类单元。达科特链霉菌(S.dakotensis)的分布与类似链霉菌(S.similis)几乎是异基因的。

Abstract. A long and steep elevational gradient presents the opportunity to study the niches of a large number of species within a small geographic area. Along such a gradient in the Sierra Nevada of California, all bryophytes were recorded in 253 plots. Along with species occurrence, the wetness, incline, shadiness and substrate type of the spot where each bryophyte was living were recorded. The average of these ecological traits (i.e., the central tendency of the species niche) was tabulated along with a determination of whether the species was a specialist or generalist for that niche dimension. Moving to guilds, co-occurrence in plots was used to aggregate species into ecological coalitions using the program RCLUS. These coalitions occupy different parts of an ordination of species, but they reveal more subtlety than the ordination itself. An ecotone was evident between the foothill bryophyte vegetation zone and a higher elevation zone. Other ecotones were not obvious; for example, we did not detect a sharp boundary between a conifer zone and a subalpine zone, rather the turnover of species was incremental and individualistic. For naturalists who know the species, being able to characterize them ecologically contributes to thoughts of the assembly of communities and the conservatism of clades.
摘要一个长而陡峭的海拔梯度为在一个小的地理区域内研究大量物种的生态位提供了机会。在加利福尼亚内华达山脉沿此梯度,记录了253个样地的所有苔藓植物。随着物种的发生,记录了苔藓植物生长地点的湿度、倾斜度、遮荫度和底物类型。将这些生态特征的平均值(即物种生态位的集中趋势)制成表格,并确定该物种是该生态位维度的专家还是通才。再转向行会,使用RCLUS程序,利用地块中的共生现象将物种聚集到生态联盟中。这些联盟占据了物种协调的不同部分,但它们揭示了比协调本身更微妙的东西。山麓苔藓植被带与高海拔苔藓植被带之间存在明显的过渡带。其他交错带不明显;例如,我们没有发现针叶林带和亚高山带之间有明显的界限,而是物种的更替是增量的和个人的。对于了解该物种的博物学家来说,能够从生态学上描述它们的特征有助于思考群落的聚集性和进化支的保守性。

Abstract. Incongruence among morphological and different molecular data sets can be troublesome for species and genus circumscriptions and may cause problems in interpreting intraspecific relationships. Based on the nuclear ITS1 and 2, and the plastid rpl16, trnG and trnL-trnF, it is shown that while such incongruence is not detected if the individual species Loeskypnum badium, Sarmentypnum exannulatum or Warnstorfia fluitans are studied, it may be striking when analyzed in a wider context within the Calliergonaceae. The wider context did not affect the interpretation of internal relationships within L. badium, but many specimens of the other two species were suggested to belong to different species by either marker set. For a large minority of S. exannulatum (8% of specimens), ITS suggested W. fluitans and for 28% of W. fluitans the plastid markers suggested S. exannulatum or (one case) S. sarmentosum. The found pattern agrees with a scenario where archegonia of female plants of S. exannulatum or S. sarmentosum were fertilized by W. fluitans spermatozoids. The produced spores all have the maternally inherited Sarmentypnum plastids, but nuclear genome portions from either the involved Sarmentypnum species or W. fluitans. If foreign plastids affect the functionality of plants less than foreign nuclear portions in plants with mixed genomes, morphological W. fluitans plants with Sarmentypnum plastids should survive to a higher degree than vice versa.
摘要形态学和不同分子数据集之间的不一致可能会给种和属的界定带来麻烦,并可能导致解释种内关系的问题。基于核ITS1和2,以及质体rpl16、trnG和trnL-trnF,研究表明,虽然在单独研究Loeskypnum badium、Sarmentypnum exannulatum或Warnstorfia fluitans时没有检测到这种不一致性,但在更广泛的背景下分析Calliergonaceae时,这种不一致性可能是惊人的。更广泛的背景没有影响L. badium内部关系的解释,但其他两个物种的许多标本被认为属于不同的物种。对于绝大多数(8%的标本),ITS提示为流感芽孢杆菌,而对于28%的流感芽孢杆菌,质体标记提示为exannulatum或smentosum(1例)。发现的模式与沙芽草或沙芽草雌性植物的卵母细胞被W. fluitans的精子受精的情况一致。产生的孢子都有母系遗传的沙门菌质体,但核基因组部分来自相关的沙门菌或W. fluitans。在混合基因组的植物中,如果外源质体对植物功能的影响小于外源核部分的影响,那么带有沙门属质体的形态氟霉属植物的存活率要高于反之。

Abstract. Environmental factors in saxicolous lichen communities are scale dependent, yet the influence of scale is not often specifically addressed in ecological studies. This study examined three scales [micro (cm), meso (meters–10s of meters), macro (km)] in granite rock communities and compared species assemblages and disturbance regimes in Lake Superior shoreline and inland habitats. Percent cover of lichens and environmental variables were measured in 1280 20 × 20-cm plots across 16 sites (8 lakeshore and 8 inland). A perMANOVA analysis showed that the composition of lakeshore and inland lichen communities was significantly different (F=17.2, df=1,4, P <0.001). Adjacent lakeshore sites were more similar (F=8.550; df = 1, 26; p=0.007) to each other than they were to sites further away, while inland sites were not (F=0.545; df=1, 26; p=0.467). Variation in disturbance is likely more important in determining inter-site variation in inland areas. Mesoscale environmental variables such as solar radiation, height above Lake Superior, and an aspect/slope index were better predictors of species assemblages than microscale variables. However, individual species differed greatly in their associations with specific habitat variables. A host of microhabitats were discovered, with some lichens specializing on rock overhangs, quartz veins, cracks, subtle variations in rock texture, and mafic intrusions within granite.
摘要沙囊地衣群落的环境因子依赖于尺度,但尺度的影响在生态学研究中往往没有得到具体的解决。本研究考察了花岗岩群落的三个尺度[微观(厘米)、中观(米- 10米)和宏观(公里)],并比较了苏必利尔湖岸线和内陆栖息地的物种组合和干扰制度。对16个样地(8个湖滨和8个内陆)1280个20 × 20 cm样地的地衣覆盖度和环境变量进行了测量。perMANOVA分析显示,湖岸与内陆地衣群落组成差异显著(F=17.2, df=1,4, P <0.001)。邻近湖滨站点更相似(F=8.550;Df = 1,26;p=0.007),而内陆地区则没有(F=0.545;df = 1, 26岁;p = 0.467)。在确定内陆地区的站点间变化时,扰动的变化可能更为重要。中尺度环境变量如太阳辐射、苏必利尔湖以上高度和坡向指数比微尺度变量更能预测物种组合。然而,不同物种与特定生境变量的关联存在很大差异。发现了许多微栖息地,一些地衣专门生长在岩石悬垂、石英脉、裂缝、岩石纹理的细微变化和花岗岩内的基性侵入物上。

Abstract. Japanese gardens emphasize on the aesthetic value of bryophytes, a major ground cover in moss gardens. Using medieval and early modern documents, this study analyzed the evolution of moss gardens and their aesthetic value by elucidating how moss usage changed over time. Twenty documents written from the 11th to the 19th centuries were surveyed. According to these documents, mosses were used as supplemental ground cover around the 11th century. After the 15th century, mosses were intentionally selected and planted in Zen gardens (gardens established at Zen temples) and Roji (gardens attached to tea ceremony rooms). Zen gardens provide monks with a feeling of being deep in the mountains. Roji particularly emphasizes Wabi-Sabi aesthetics, which embrace the opposite of conventional beauty, such as aging processes and tranquility. These concepts in Zen and Roji gardens are associated with bryophyte-covered landscapes. This is because these landscapes suggest a mountain-like ambiance, the passage of time, and tranquility in Japan. These associations suggest that the importance of bryophyte cover in gardens might have increased with the development of Zen and Roji gardens—specifically, mosses came to be used as major ground cover after the establishment of Roji. Moreover, given that Zen Buddhism underlies the establishment of Wabi-Sabi aesthetics, it might have been the impetus for the development of moss gardens.
摘要日本园林强调苔藓植物的美学价值,苔藓植物是苔藓花园的主要地被植物。本研究利用中世纪和现代早期的文献,通过阐明苔藓的使用是如何随着时间的推移而变化的,分析了苔藓花园的演变及其美学价值。调查了11世纪至19世纪的20份文献。根据这些文献,苔藓在11世纪左右被用作补充地被植物。15世纪以后,人们有意在禅宗花园(在禅宗寺庙建立的花园)和Roji(附属于茶道室的花园)中选择并种植苔藓。禅宗花园为僧侣们提供了一种身处深山的感觉。Roji特别强调Wabi Sabi美学,它与传统美相反,如衰老过程和宁静。禅宗和罗济园林中的这些概念与苔藓植物覆盖的景观有关。这是因为这些景观暗示了日本的山脉般的氛围、时间的流逝和宁静。这些关联表明,苔藓植物覆盖在花园中的重要性可能随着禅宗和罗济花园的发展而增加——特别是,在罗济建立后,苔藓开始被用作主要的地面覆盖物。此外,考虑到禅宗是瓦比沙比美学的基础,它可能是苔藓花园发展的动力。

Abstract. We used data on epiphytic lichen communities in 1215, 0.4-ha plots in the Southwest U.S.A. collected by the Forest Inventory and Analysis (FIA) program to analyze relationships with climate. We sought the climate variables most strongly associated with differences in epiphytic macrolichen communities and described the nature of those relationships, including diversity, community composition, and patterns in individual species. Five lichen community groups were strongly related to temperature and elevation gradients, overall moisture, and summer rain. Lichen abundance was highest in the wettest groups and lowest in the hottest and driest groups. Warm summer monsoonal climates supported the greatest number of species across all plots and within plots. The monsoonal pattern did not occupy a discrete geographic area, but instead formed a gradient, strongest in the southern part of our study area, diminishing to the north and west. In contrast, hot summer monsoonal climates had much lower within-plot richness. Hot, dry climates had the most variation in species composition among plots, but the fewest species within each plot and across all plots. Lichen community gradients had nonlinear relationships with combinations of climate variables rather than strong linear relationships with any single variable, including those derivative climate variables meant to have direct biological relevance. Relationships between air quality and community gradients were weak, potentially overwhelmed by regional climatic variation and complex topographic gradients. Richness of particular functional groups was more strongly related to climate than was overall species richness; functional groups have their own climatic tolerances, owing to the physiological consequences of growth form and photobiont. Presumably species in different functional groups have experienced their own evolutionary tradeoffs, developing peak performance in different climates. On the other hand, overall richness was driven by an even more complex combination of performances relative to climate and was in some functional groups more strongly related to geographic coordinates than to climate variables. Because climatic variables are themselves geographically structured, stronger model fit for geographic coordinates than for climate implies some influence of large-scale historical factors (i.e., factors not clearly expressed in modern climates, such as past climates, vegetation structure, or disturbance regimes).
摘要本文利用美国西南部森林资源调查与分析(FIA)项目收集的1215个0.4 ha样地附生地衣群落数据,分析其与气候的关系。我们寻找与附生大地衣群落差异最密切相关的气候变量,并描述了这些关系的本质,包括多样性、群落组成和单个物种的模式。5个地衣群落群与温度和海拔梯度、总湿度和夏季降雨密切相关。地衣丰度在最潮湿组最高,在最炎热和最干燥组最低。温暖的夏季季风气候在各样地和样地内支持的物种数量最多。季风模式并没有占据一个离散的地理区域,而是形成了一个梯度,在研究区南部最强,向北和向西减弱。相反,炎热夏季季风气候的样内丰富度要低得多。炎热、干燥气候的样地间物种组成差异最大,但样地内和样地间物种组成差异最小。地衣群落梯度与气候变量的组合呈非线性关系,而与任何单一变量(包括那些具有直接生物学相关性的衍生气候变量)均呈强线性关系。空气质量与群落梯度之间的关系较弱,可能被区域气候变化和复杂的地形梯度所掩盖。与总体物种丰富度相比,特定功能群丰富度与气候的相关性更强;由于生长形式和光生物的生理影响,官能团有自己的气候耐受性。据推测,不同功能群的物种经历了自己的进化权衡,在不同的气候条件下发展出最佳表现。另一方面,总体丰富度是由与气候相关的更复杂的表现组合驱动的,并且在一些功能组中与地理坐标的关系比与气候变量的关系更强。由于气候变量本身具有地理结构,因此对地理坐标的模式拟合强于对气候的模式拟合,意味着大尺度历史因素(即,在现代气候中未明确表达的因素,如过去的气候、植被结构或扰动制度)的一些影响。
