ABSTRACT The moss family Orthotrichaceae is still poorly known in the southern extreme of South America. This is especially true regarding the morphological variability, geographical distribution, and ecological affinities of the species restricted to the Andean-Patagonian area. These deficiencies are addressed for Orthotrichum gigantosporum Lewinsky, one of the least known and most interesting endemics of the area. After examining the rich collections made by our team in southern Chile and Argentina, we have found numerous new localities for the species. Orthotrichum gigantosporum has proven to be a widespread moss in the forests and scrublands of the northern sector of the Andean-Patagonian area. In the light of new morphological data, an updated description of the species is presented and the characteristics that allow its differentiation are discussed and illustrated. The ecological data obtained on the populations also help to characterise the distribution of this moss in relation to various environmental factors. An updated list of the accepted species of Orthotrichaceae present in the Andean-Patagonian area is also provided, facilitating an estimate of endemicity rates within each genus.
在南美洲的最南端,藓科植物仍然鲜为人知。这一点在安第斯-巴塔哥尼亚地区物种的形态变异、地理分布和生态亲和性方面尤其如此。莱温斯基正藓属(Orthotrichum gigantosporum Lewinsky)是该地区最不为人知和最有趣的地方性植物之一,这些缺陷都得到了解决。在检查了我们的团队在智利南部和阿根廷收集的丰富标本后,我们发现了该物种的许多新地点。在安第斯-巴塔哥尼亚地区北部的森林和灌木丛中,巨孢藓已经被证明是一种广泛存在的苔藓。根据新的形态学资料,提出了一种更新的物种描述,并讨论和说明了允许其分化的特征。获得的种群生态数据也有助于描述这种苔藓的分布与各种环境因素的关系。还提供了安第斯-巴塔哥尼亚地区存在的公认的原木科物种的最新清单,以便估计每个属内的特有率。

ABSTRACT The epiphytic bryophyte communities of the Altindere Valley (Maçka, Trabzon, Turkey) were studied. A total of 59 relevés, taken from living tree trunks in different vegetation periods of 2018 and 2020, were analysed according to the Braun-Blanquet methodology, and the relevés were also ordinated and classified using the Detrended Correspondence Analysis (DECORANA) and the Two-Way Indicator Species Analysis (TWINSPAN). As a result of the analyses, Alleniella besseri-Leucodontetum immersi as. nov., Plagiomnio undulati-Raduletum lindbergianae typicum and P.-R. leucodontetosum sciuroidis subas. nov. (Neckerion complanatae) were described and characterised as a new epiphytic. Mnietum cuspidati, Homalothecio sericei-Neckeretum besseri and Brachythecietum populei-isothecietosum alopecuroidis were also described as new to Turkey, whereas Brachythecietum populei typicum was recorded for the second time in Turkey.

Does the Removal of Non-Photosynthetic Sections Lead to a Down-Regulation of Photosynthesis in Mosses? A First Experiment 非光合部分的去除会导致苔藓植物光合作用的下调吗?第一次实验

ABSTRACT When measuring photosynthesis in mosses, the non-photosynthetic (brown) sections are usually removed and only the green sections are measured. However, how this pretreatment affects photosynthesis rates is unclear. Therefore, we studied the effect of removing the non-photosynthetic sections in three moss species with distinct morphological and stem-anatomical structures, comparing net CO2 assimilation rates (AN) of detached green and brown sections to those of intact shoots. Right after separation, the summed AN of the separated sections was significantly lower than those of the intact shoots for Pogonatum nudiusculum Mitt. and Pleuroziopsis ruthenica (Weinm.) Kindb. ex E. Britton, while no significant difference was found for Actinothuidium hookeri (Mitt.) Broth. However, AN recovered within a day, and the progressive reduction of AN expected if carbon-sink removal was an important mechanism was not observed. Our study indicates that removal of non-photosynthetic sections results in an underestimation of the photosynthetic capacity of the green moss sections, but only for the species with relatively complex internal transport structures, and only immediately after the separation. The fast and transient response suggests a mechanism via an electrical signal induced by wounding or reduced hydraulic integrity, rather than through a reduced carbon-sink strength. More comprehensive investigations on signaling and other mechanisms regulating moss photosynthesis will contribute to more accurate measurement methods as well as a deeper understanding of moss ecophysiology and the contribution of mosses to carbon fluxes in terrestrial ecosystems.
在测量苔藓的光合作用时,通常会去掉非光合作用(棕色)部分,只测量绿色部分。然而,这种预处理如何影响光合作用速率尚不清楚。因此,我们研究了三种形态和茎解剖结构不同的苔藓物种去除非光合部分的效果,比较了分离的绿色和棕色部分与完整枝条的净CO2同化率(AN)。刚分离后,裸子嫩枝的总氮显著低于完整嫩枝的总氮。和鲁thenica (Weinm.)Kindb。例如E. Britton,而Actinothuidium hookeri (Mitt.)没有发现显著差异。汤。然而,AN在一天内恢复,如果碳汇去除是重要机制,则未观察到AN的逐步减少。我们的研究表明,去除非光合部分会导致低估青苔部分的光合能力,但仅适用于内部运输结构相对复杂的物种,并且仅在分离后立即进行。快速而短暂的响应表明,这种机制是由损伤或液压完整性降低引起的电信号引起的,而不是碳汇强度降低。对苔藓光合作用的信号和其他调节机制进行更全面的研究,将有助于提供更准确的测量方法,以及更深入地了解苔藓的生态生理和苔藓对陆地生态系统碳通量的贡献。

Checklist of the Liverworts and Hornworts of French Polynesia 法属波利尼西亚的苔属和角属植物名录

ABSTRACT The present publication is the first modern catalogue of the liverworts and hornworts of French Polynesia and accepts 161 species of liverworts and 5 species of hornworts. In addition, 40 species are doubtful records of French Polynesia and 45 species are excluded. The checklist is mainly based on a compilation of published records; a few unpublished new records are included as well. The region has been explored very unevenly and liverwort and hornwort records are available for only ten islands of French Polynesia. Several islands of considerable surface area and elevation such as Futa Hiva, Tahuata, Ua Pou and Ua Huka in the Marquesas, and Huahine and Tahaa in the Society Islands remain completely unexplored. In the Tuamotu Archipelago, only one atoll of the 60 has been surveyed (Makemo) and the number of reports for Gambier islands is quite low. The hepatic flora of French Polynesia appears to be relatively poor in species as compared to other Pacific island groups, such as the Fiji Islands (301 spp.) and New Caledonia (475 spp.) which are large continental islands (over 18 000 km2). Nevertheless, their floras show strong similarities at the family level. One species, Treubia tahitensis (Nadeaud) Besch., is only known from French Polynesia and may be considered endemic. The lack of endemic hepatic species in French Polynesia may be explained by the relatively small size, rather low elevation, low habitat diversity and recent geological age of the islands. It supports the notion that oceanic barriers do not operate as a major impediment to bryophyte dispersal.
本出版物是法属波利尼西亚的第一个苔类和角苔类现代目录,收录了161种苔类和5种角苔类。此外,法属波利尼西亚有可疑记录的有40种,已排除的有45种。核对表主要基于已发表记录的汇编;一些未发表的新记录也包括在内。该地区的勘探非常不均匀,只有法属波利尼西亚的十个岛屿有苔类和角苔类的记录。一些面积和海拔相当大的岛屿,如马克萨斯群岛的Futa Hiva、Tahuata、Ua Pou和Ua Huka,以及社会群岛的Huahine和Tahaa,仍然完全没有被勘探过。在土阿莫土群岛,60个环礁中只有一个(Makemo)被调查过,而甘比尔岛的报告数量相当少。与斐济群岛(301种)和新喀里多尼亚(475种)等其他太平洋岛屿群(超过1.8万平方公里)相比,法属波利尼西亚的肝脏菌群似乎相对较少。然而,它们的植物区系在科水平上表现出强烈的相似性。塔希提Treubia tahitensis (Nadeaud) Besch一种。仅在法属波利尼西亚发现,可能被认为是地方性的。法属波利尼西亚缺乏特有的肝脏物种可能是由于岛屿面积相对较小、海拔较低、栖息地多样性低和地质年代较近。它支持这样一种观点,即海洋屏障不是苔藓植物扩散的主要障碍。

ABSTRACT In this study, three deadwood-dependent liverwort species (Calypogeia suecica (Arnell & J.Perss.) Müll. Frib., Crossocalyx hellerianus (Nees ex Lindenb.) Meyl. and Scapania apiculata Spruce) are reported upon from forests of North-western Anatolia for the first time for Turkey and Southwest Asia. The results concluded an increasing number of Scapania species to 17, Calypogeia species to six for these areas. Also, Crossocalyx is a new genus record for Turkey and Southwest Asia. All three new records are approximately at the southernmost limit of these species' distribution of Western Asia; also records of C. hellerianus and S. apiculata are at the southern limit of their Mediterranean distribution. Morphological descriptions, microphotographs, ecological aspects, distinctive taxonomical features, and Turkish conservation suggestions of the new records are presented. In addition, some remarkable deadwood-dependent bryophyte species (Buxbaumia viridis (Moug. ex Lam. & DC.) Brid. ex Moug. & Nestl., Fuscocephaloziopsis lunulifolia (Dumort.) Váňa & L.Söderstr. and Lophozia guttulata (Lindb. & Arnell) A.Evans.) in Turkey are discussed.
在本研究中,三种依赖枯木的苔类植物Calypogeia suecica (Arnell & J.Perss.)考虑。Frib。,向日葵交叉花萼(同属植物)Meyl。和Scapania apiculata云杉)是土耳其和西南亚首次在安纳托利亚西北部的森林中报道的。结果表明,该地区Scapania种增加到17种,Calypogeia种增加到6种。此外,Crossocalyx是土耳其和西南亚的新属记录。这三个新记录大约都位于这些物种在西亚分布的最南端;在地中海分布的南端也有记录的C. hellerianus和S. apiculata。介绍了新记录的形态描述、显微照片、生态方面、独特的分类特征和土耳其保护建议。此外,一些显著的依赖枯木的苔藓植物(黄腐草(Buxbaumia viridis);前女友。和直流。)Brid。Moug交货。& Nestl。、褐头藻(Dumort.)Váňa & L.Söderstr。和Lophozia guttulata (Lindb.;& Arnell) A.Evans.)在土耳其进行了讨论。

ABSTRACT Frullania diversitexta Steph. currently occupies its own subgenus, subg. Diversitextae (Kamim.) S.Hatt., although its taxonomic placement is somewhat enigmatic. The habit of the species, as well as the position and shape of the lobules, are morphologically comparable to species in subg. Diastaloba Spruce and subg. Frullania Spruce, whereas its tuberculate perianth ornamentation is reminiscent of species in subg. Trachycolea Spruce. Here, molecular sequence data resolves F. diversitexta within subg. Trachycolea in a relationship with F. plana Sull. (sect. Planae R.M.Schust.). Frullania diversitexta and F. plana have a similar branching pattern, leaf lobe shape, leaf cell areolation, stylus, lobule position, underleaf shape and primary branch appendages that often have two saccate lobules. Differences in their lobule shape, sexuality, position of the gynoecia and perianth ornamentation, however, decidedly warrant the placement of F. diversitexta in its own section, sect. Diversitextae (Kamim.) J.J.Atwood, Vilnet & Mamontov, stat. nov. Lectotypes are designated for F. diversitexta and its three synonyms: F. abducens Steph., F. sendaica Steph. and F. tosana Horik. (replaced synonym of F. tenella Steph., hom. illeg.). Frullania ignatovii Sofronova, Mamontov & Potemkin, having obovoid, skull shaped lobules with an unusual bilabiate mouth, is also resolved within subg. Trachycolea, in a sister relationship with F. davurica Hampe and F. jackii Gottsche.
frulania diversitextextsteph .;目前占据了它自己的亚属,subg。Diversitextae (Kamim)。S.Hatt。尽管它的分类位置有些神秘。该物种的习性,以及小叶的位置和形状,在形态学上与subg中的物种相似。隔片瓣云杉和近瓣。frulania云杉,而其具结核的花被装饰是在subg的忆及种。Trachycolea云杉。这里,分子序列数据在subg中解析了F. diversitextra。与F. plana Sull的关系。(Planae r.m.s ust节)。牛油果和牛油果具有相似的分枝模式、叶片形状、叶细胞环折、茎尖、小叶位置、叶下形状和常有两个囊状小叶的初级分枝附属物。然而,它们在小叶形状、性别、雌蕊位置和花被装饰上的差异,明确地保证了F. diversitexa在其自己的部分,节。Diversitextae (Kamim)的位置。J.J.Atwood, Vilnet & Mamontov, stat11 . Lectotypes被指定为F. diversitextra和它的三个同义词:F. abducens Steph。, F. sendaica Steph。和F. tosana Horik。(取代了F. tenella Steph的同义词。力宏。illeg)。Frullania ignatovii Sofronova, Mamontov & Potemkin,具有倒卵形头骨状小叶和不寻常的双唇嘴,也在subg中被解决。气管菌,与F. davurica Hampe和F. jackii Gottsche有姐妹关系。
