ABSTRACT The level of knowledge on the hornwort and liverwort flora of Serbia has increased in recent decades. Based on a thorough review of the literature and herbarium data, an updated list of the hepatic and liverwort taxa present in Serbia is compiled and presented. Taking into account recent taxonomic and nomenclatural changes, totals of 133 species and six infraspecific taxa are reported for the country. An additional eight species are rejected with explanatory annotations. The list includes data on the presence of taxa in separate regions and counties of the country.

ABSTRACT A taxonomic revision of the liverwort family Aneuraceae in eastern Africa is presented based on the results of an integrative approach. Molecular and morphological data lead to the recognition of fourteen species in eastern Africa, in three genera: eleven species in Riccardia Gray, two in Aneura Dumort. and one in Afroriccardia Reeb & Gradst. One further species, R. multifida, may be expected in eastern Africa and is included in this treatment. Keys, descriptions and illustrations are provided for the accepted species together with data on types, synonymy, geographical distribution, habitat and differentiating characters. A knowledge database was built using Xper3 and an interactive key was generated using the Xper3 platform tools. Riccardia gasparii sp. nov., R. martinii sp. nov. and R. vohimanensis sp. nov. are described as new to science. A comparison with other regions of the world shows that Africa has relatively few Aneuraceae taxa; only the Holarctic region, with the exception of East Asia, has fewer species. Moreover, dendroid taxa and species with cuticular ornamentation are lacking in Africa. On the other hand, Africa stands out by the presence of the endemic genus Afroriccardia. More collecting is needed in future to clarify the species ranges, the status of questionable taxa and the knowledge of local floras.

ABSTRACT Riella affinis Howe & Underwood is a rare species that is thus far known from eight populations worldwide. Only half of these were recorded in the last 50 years and none were recollected since first reported. Study of a Spanish population of R. cossoniana Trab., recorded in 2002 from Las Lomas, Malaga province, revealed that it belongs to R. affinis. The correct identity of the populations, which had not been available for study, was already suggested by reproductive and ecological characteristics of the plants mentioned in the original publication. The three main lagoons from the Las Lomas endorheic system, where the plants had been recorded, were sampled and living plants of R. affinis were found in Viso lagoon whereas culture of sediments yielded plants of this species from Viso and Caja lagoons. Riella affinis is new to continental Europe and the new Spanish populations are described and illustrated in detail. Riella cossoniana is excluded from Malaga province. Riella affinis is classified as critically endangered (CR) globally and for Spain; the new Iberian populations should be targeted for conservation. An identification key to the currently recognised European species of Riella Mont. is included.

ABSTRACT Studies of the Tunisian bryoflora are disparate and mostly quite outdated. In order to enhance and update our knowledge, a survey of Anthocerotophyta and Marchantiophyta of Kroumiria was carried out in May 1-5, 2017, recording two hornworts and 30 liverworts including Riccia gougetiana Durieu & Mont. var. armatissima Levier ex Müll.Frib., new to the area. The liverwort and hornwort flora of Kroumiria now stands at 80 reliably recorded taxa, of which 22 species may be threatened. Numerical analyses were used to specify the requirements of the 32 listed taxa for substrate, light, temperature and humidity and to distinguish seven different ecological groups ranging from the hydro-thermo-photophile to the mesohygro-sciaphile.

ABSTRACT Hornworts are globally the least diverse bryophyte group with respect to species number, with only eight species known from Europe. As for Croatia, only two species are listed in the available literature, with most recent record being more than 85 years old. Our study carried out in Central Croatia identified three new species for the hornwort flora, including two new genera – Notothylas Sull. ex. A. Gray and Anthoceros L. Our finding of very rare Natura 2000 species Notothylas orbicularis (Schwein.) A. Gray, reported hitherto only from four Central European countries, is the first in Southeast Europe and the southernmost in Europe. Furthermore, we recorded Anthoceros agrestis Paton and Phaeoceros carolinianus (Michx.) Prosk., which are either very rare or, more likely, overlooked and understudied in Southeast Europe.

ABSTRACT Cinclidotus confertus Lüth was described in 2002 from Greece and has to date only been recorded from the type locality. The taxon was supposed to differ from the widespread C. riparius (Host ex Brid.) Arn. in the red and papillose peristome teeth, as opposed to yellow and smooth peristome teeth of C. riparius. However, we found that the peristome of C. riparius was inconsistently described in the bryological literature, with some authors admitting reddish and papillose peristome teeth as well. To clarify the peristome characteristics of C. riparius and the taxonomic identity of C. confertus we studied both taxa morphologically and molecularly. Sporophyte characteristics of C. riparius are variable, but most specimens have red and papillose peristome teeth, and no other morphological difference could be found between plants assigned to C. confertus and C. riparius. The many erroneous or incomplete descriptions of the peristome characteristics of C. riparius may be related to the fact that in central Europe sporophytes are rarely produced and that the fragile peristome easily erodes. Furthermore, the phylogenetic analysis of chloroplast rps4 and nuclear ITS2 loci failed to segregate specimens assigned to C. riparius from those assigned to C. confertus, including material from the type locality and further newly discovered localities of the latter taxon. Consequently, we propose the synonymy of both taxa.
cclinlidotus conftus l于2002年在希腊被描述，迄今为止仅在模式地点有记录。该分类群被认为不同于广泛分布的C. riparius (Host ex Brid.)。在攻击。在红色和乳头状的壁壁牙中，相对于黄色和光滑的河滨草的壁壁牙。然而，我们发现，在苔藓学文献中，对河鼠胃壁的描述并不一致，一些作者也承认其胃壁有红色和乳头状的牙齿。为进一步阐明河青的肠壁特征和河青的分类特性，从形态学和分子生物学两方面对河青进行了研究。河青的孢子体特征各不相同，但大多数标本具有红色和乳突状的壁壁齿，在其他形态上没有发现河青与河青的区别。关于河柳叶枯壁特征的许多错误或不完整的描述可能与中欧很少产生孢子体和脆弱的枯壁容易被侵蚀有关。此外，叶绿体rps4和核ITS2基因座的系统发育分析也无法区分出河青(C. riparius)和孔丘(C. contus)的标本，包括来自模式地的材料和新发现的孔丘的材料。因此，我们提出这两个分类群的同义词。

ABSTRACT Trematodonl laetevirens Hakelier & J.-P. Frahm is here added to the Russian bryoflora based on records from the Khibiny Mts. (Murmansk Region, North-West Russia), Anadyr' River Basin (Chukotka Autonomous Region) and the Ushkovsky volcano (Kamchatka Peninsula). The Khibiny moss population, earlier defined as T. brevicollis Hornsch., is attributed to T. laetevirens. We reaffirmed that the East Sayan samples belong to T. brevicollis, so, currently only one locality of T. brevicollis is known in Russia. The revision of T. longicollis Michx. samples from the Kamchatka Peninsula, and Kunashir Island (the Kuril Islands) confirmed their affiliation to this species, despite some deviations in morphological features. The taxonomical concepts inferred from variation in morphological traits are supported by for the first molecular-phylogenetic analyses of the genus Trematodon based on the nucleotide sequence data of ITS2 nrDNA and trnL-F cpDNA. At present, four species of the genus Trematodon Michx. are known from Russia: T. ambiguus (Hedw.) Hornsch., T. brevicollis, T. laetevirens and T. longicollis. A key to Russian Trematodon species is provided.
[摘要]龋病防治[j]。根据来自希比尼山脉(俄罗斯西北部摩尔曼斯克地区)、阿纳德尔河流域(楚科奇自治区)和乌什科夫斯基火山(堪察加半岛)的记录，弗拉姆被添加到俄罗斯苔藓植物中。希比尼苔藓种群，早先被定义为T. brevicollis Hornsch。这是由T. laetevirens引起的。我们确认东萨扬的样本属于短链绦虫，因此，目前在俄罗斯只知道一个短链绦虫的地点。长鼻绦虫的修订。堪察加半岛和库纳希尔岛(千岛群岛)的标本证实了它们属于这个物种，尽管在形态特征上有一些偏差。基于ITS2 nrDNA和trl - f cpDNA的核苷酸序列数据，首次对吸虫属进行了分子系统发育分析，支持了从形态特征变异推断的分类概念。目前发现吸虫属4种。来自俄罗斯:T. ambiguus (Hedw.)Hornsch。短支绦虫、长支绦虫和长支绦虫。提供了俄罗斯吸虫种类的分类表。

ABSTRACT Elevational gradients can serve as powerful tools for testing ecological relationships between species richness versus environmental variables. Although the patterns be usually from positive to humped-shaped, elevational gradients may run in a negative way with the species richness decreasing in relation to the altitude. The floristic gradient may vary according species biology, site and, scale for analyses. Therefore, elevational gradient can be useful for detecting points for biological conservation and may be analized by using sensitive species as approach for others species including banner-species. Along an elevational gradient in a harsh semiarid environment we are showing a negative relationship between bryophyte species richness and increasing elevation. The observed floristic gradient reflects environmental constraints related to light requirements and low humidity as environmental conditions become more severe at higher altitudes, where anthropogenic activities such as farming dramatically alter the vegetation covering. The diversity of bryophytes in terms of their light requirements makes them excellent bioindicators of environmental quality. We provide data that will be useful for conservation planning and management, and report species with rare distributions in Brazil and others not yet recorded as occurring in dry forests.
