Catálogo de los briófitos epífitos que crecen en bosques de quercíneas del cuadrante noroccidental ibérico

[ES] En las últimas décadas se han producido importantes avances en el conocimiento de la brioflora ibérica. Gracias a ello se puede decir que hoy día la flora muscinal ibérica se conoce relativamente bien a nivel taxonómico. Sin embargo, en cuanto a las distribuciones de las especies aún queda mucho trabajo por hacer. La mayor parte de los estudios se han centrado en zonas montanas y/o singulares o bien en los entornos de las residencias de los especialistas. Esto ha producido un importante sesgo en el conocimiento de las distribuciones que es necesario solventar realizando estudios sistemáticos centrados en conseguir una muestra representativa de los principales gradientes ambientales y geográficos de la Península. Precisamente, el objetivo del presente trabajo es contribuir a reducir de forma significativa las lagunas en el conocimiento de la distribución de los briófitos epífitos ibéricos. Para ello, se ha estudiado buena parte de las mesetas centrales, incluyendo las porciones españolas de las cuencas del Duero y del Tajo, dos de las regiones menos exploradas de la Península Ibérica. El catálogo resultante incluye 89 especies de briófitos, entre las que hay 9 hepáticas y 80 musgos. El presente estudio aporta además 72 nuevas citas provinciales y amplía significativamente la distribución conocida de un buen número de especies. Queda patente la importancia de llevar a cabo muestreos sistemáticos representativos de los gradientes ambientales y geográficos en zonas poco exploradas de modo que se vayan rellenando los huecos en el conocimiento de las distribuciones de los briófitos ibéricos.[EN] Knowledge on the diversity and distributions of the Iberian bryophytes has experienced a remarkable progress in the last decades. As a consequence, the taxonomy of the Iberian bryophytes is relatively well known. However, regarding the distribution and abundance of species across the territory large knowledge gaps e xist. To date, most of the studies have been centered either in mountainous regions or in singular areas or accessible sites in the vicinity of specialist's residences. This has produced important sampling biases in the knowledge on the species distributions. Thus, to improve the quality of the data at hand, it is necessary to perform systematic surveys focused on attaining a representative sample of the main geographic and environmental gradients of the Iberian Peninsula. Within this broad objective the specific aim of this work is to contribute to significantly reduce the knowledge gaps on the distribution of Iberian epiphytic bryophytes. To do so, we have studied a large part of the Iberian plateaus including the Duero and Tajo basins within the Spanish territory, two of the least explored regions within the Iberian Peninsula. The obtained catalogue includes 89 bryophyte species including 9 liverworts and 80 mosses. Besides, we provide 72 provincial novelties that significantly enlarge the known distribution of a number of species. Altogether these results evidence that to fill in current knowledge gaps it is necessary to perform systematic survey campaigns aimed at representing the geographic and environmental variability of the territory.Este trabajo ha sido financiado por los proyectos concedidos por el Ministerio de Economía y Competitividad (CGL2013-43246-P) y el Ministerio de Ciencia e Innovación (CGL2011-28857/BOS) españoles.

Epiphytic bryophytes of Quercus forests in Central and North inland Iberian Peninsula

Frontiers of Biogeography 7.1 (2015): 21-28 This Document is Protected by copyright and was first published by Frontiers. All rights reserved. It is reproduced with permissionDiversity patterns are governed by a complex network of interacting factors. Studies directed to disentangle the most important factors affecting diversity have frequently shown divergent results, which has encouraged a rewarding debate about the relative importance of each factor. Scale dependency has been identified as a direct cause of at least part of such divergences. However, studies with spatially-explicit measurements at different scales are costly and therefore they are relatively scarce despite their importance. Here, we present a database to disentangle the cross-scale variation in the importance of factors affecting the diversity of epiphytic bryophyte communities in Quercus dominated forests (Quercus ilex L., Quercus pyrenaica Willd. and Quercus faginea Lam.) in the North-western region of the Iberian Peninsula. We provide species-per-site abundance information with more than 9000 entries and an environmental table containing 20 in situ measured variables at three different scales (forest, stand, and sample). The database will help to advance the research of cross-scale effects of diversity patterns while at the same time providing valuable information on the distribution of a poorly known group of organismsThe fieldwork was funded by the Spanish Government through grants CGL2007-61389, CGL2010-15693 and CGL2011-28857.

The long journey of Orthotrichum shevockii (Orthotrichaceae, Bryopsida): From California to Macaronesia

This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. Biogeography, systematics and taxonomy are complementary scientific disciplines. To understand a species' origin, migration routes, distribution and evolutionary history, it is first necessary to establish its taxonomic boundaries. Here, we use an integrative approach that takes advantage of complementary disciplines to resolve an intriguing scientific question. Populations of an unknown moss found in the Canary Islands (Tenerife Island) resembled two different Californian endemic species: Orthotrichum shevockii and O. kellmanii. To determine whether this moss belongs to either of these species and, if so, to explain its presence on this distant oceanic island, we combined the evaluation of morphological qualitative characters, statistical morphometric analyses of quantitative traits, and molecular phylogenetic inferences. Our results suggest that the two Californian mosses are conspecific, and that the Canarian populations belong to this putative species, with only one taxon thus involved. Orthotrichum shevockii (the priority name) is therefore recognized as a morphologically variable species that exhibits a transcontinental disjunction between western North America and the Canary Islands. Within its distribution range, the area of occupancy is limited, a notable feature among bryophytes at the intraspecific level. To explain this disjunction, divergence time and ancestral area estimation analyses are carried out and further support the hypothesis of a long-distance dispersal event from California to Tenerife IslandThis research was funded by the Spanish Ministry of Education and Science (CGL2007- 61389/BOS) to F.L., the Spanish Ministry of Science and Innovation (CGL2011-28857/BOS) to V.M., the Spanish Ministry of Economy and Competitiveness (CGL2013-43246-P) to R.G., and the Spanish Ministry of Economy, Industry and Competitiveness (CGL2016-80772-P) to I.D. and the Spanish Ministry of Economy and Competitiveness (grants IJCI-2014-19691 and RYC-2016-20506) to J.P.

An NGS-based phylogeny of Orthotricheae (Orthotrichaceae, Bryophyta) with the proposal of the new genus Rehubryum from Zealandia

Phylogenomic data increase the possibilities of resolving the evolutionary and systematic relationships among taxa. This is especially valuable in groups with few and homoplasious morphological characters, in which systematic and taxonomical delimitations have been traditionally difficult. Such is the case of several lineages within Bryophyta, like Orthotrichaceae, the second most diverse family of mosses. Members of tribe Orthotricheae are common in temperate and cold regions, as well as in high tropical mountains. In extratropical areas, they represent one of the main components of epiphytic communities, both in dry and oceanic or hyperoceanic conditions. The epiphytic environment is considered a hostile one for plant development, mainly due to its low capacity of moisture retention. Thus, the diversification of the Orthotrichaceae in this environment could be seen as striking. Over the last two decades, great taxonomic and systematic progresses have led to a rearrangement at the generic level in this tribe, providing a new framework to link environment to patterns of diversification. Here, we use nuclear loci targeted with the GoFlag 408 enrichment probe set to generate a well-sampled phylogeny with well-supported suprageneric taxa and increasing the phylogenetic resolution within the two recognized subtribes. Specifically, we show that several genera with Ulota-like morphology jointly constitute an independent lineage. Within this lineage, the recently described Atlantichella from Macaronesia and Western Europe appears as the sister group of Ulota bellii from Zealandia. This latter species is here segregated in the new genus Rehubryum. Assessment of the ecological and biogeographical affinities of the species within the phylogenetic framework suggests that niche adaptation (including climate and substrate) may be a key evolutionary driver that shaped the high diversification of Orthotrichea

A miniature world in decline: European Red List of Mosses, Liverworts and Hornworts

AimThis Red List is a summary of the conservation status of the European species of mosses, liverworts and hornworts, collectively known as bryophytes, evaluated according to IUCN’s Guidelines for Application of IUCN Red List Criteria at Regional Level. It provides the first comprehensive, region-wide assessment of bryophytes and it identifies those species that are threatened with extinction at a European level, so that appropriate policy measures and conservation actions, based on the best available evidence, can be taken to improve their status.ScopeAll bryophytes native to or naturalised in Europe (a total of 1,817 species), have been included in this Red List. In Europe, 1,796 species were assessed, with the remaining 21 species considered Not Applicable (NA). For the EU 28, 1,728 species were assessed, with a remaining 20 species considered NA and 69 species considered Not Evaluated (NE). The geographical scope is continentwide, extending from Iceland in the west to the Urals in the east, and from Franz Josef Land in the north to theCanary Islands in the south. The Caucasus region is not included. Red List assessments were made at two regional levels: for geographical Europe and for the 28 Member States of the European Union.ResultsOverall, 22.5% of European bryophyte species assessed in this study are considered threatened in Europe, with two species classified as Extinct and six assessed as Regionally Extinct (RE). A further 9.6% (173 species) are considered Near Threatened and 63.5% (1,140 species) are assessed as Least Concern. For 93 species (5.3%), there was insufficient information available to be able to evaluate their risk of extinction and thus they were classified as Data Deficient (DD). The main threats identified were natural system modifications (i.e., dam construction, increases in fire frequency/intensity, and water management/use), climate change (mainly increasing frequency of droughts and temperature extremes), agriculture (including pollution from agricultural effluents) and aquaculture.RecommendationsPolicy measures• Use the European Red List as the scientific basis to inform regional/national lists of rare and threatened species and to identify priorities for conservation action in addition to the requirements of the Habitats Directive, thereby highlighting the conservation status of bryophytes at the regional/local level.• Use the European Red List to support the integration of conservation policy with the Common Agricultural Policy (CAP) and other national and international policies. For example, CAP Strategic Plans should include biodiversity recovery commitments that could anticipate, among others, the creation of Important Bryophyte Areas. An increased involvement of national environmental agencies in the preparation of these strategic plans, and more broadly in ongoing discussions on the Future CAP Green Architecture, would likely also ensure the design of conservation measures better tailored to conserve bryophytes in agricultural landscapes.• Update the European Red List every decade to ensure that the data remains current and relevant.• Develop Key Biodiversity Areas for bryophytes in Europe with a view to ensuring adequate site-based protection for bryophytes.Research and monitoring• Use the European Red List as a basis for future targeted fieldwork on possibly extinct and understudied species.• Establish a monitoring programme for targeted species (for example, threatened species and/or arable bryophytes).• Use the European Red List to obtain funding for research into the biology and ecology of key targeted species.Action on the ground• Use the European Red List as evidence to support multi-scale conservation initiatives, including designation of protected areas, reform of agricultural practices and land management, habitat restoration and rewilding, and pollution reduction measures.• Use the European Red List as a tool to target species that would benefit the most from the widespread implementation of the solutions offered by the 1991 Nitrates Directive (Council Directive 91/676/EEC), including the application of correct amounts of nutrients for each crop, only in periods of crop growth under suitable climatic conditions and never during periods of heavy rainfall or on frozen ground, and the creation of buffer zones to protect waters from run-off from the application of fertilizers.Ex situ conservation• Undertake ex situ conservation of species of conservation concern in botanic gardens and spore and gene banks, with a view to reintroduction where appropriate.</p
