-Comparable regional scale estimates for the carbon balance of forests are needed for scientific and political purposes. We developed a method for deriving these estimates from readily available forest inventory data by using statistical biomass models and dynamic modelling of litter and soil. Here, we demonstrate this method and apply it to Finland's forests between 1922 and 2004. The method was reliable, since the results obtained were comparable to independent data. The amount of carbon stored in the forests increased by 29%, 79% of which was found in the biomass and 21% in the litter and soil. The carbon balance varied annually, depending on the climate and level of harvesting, with each of these factors having effects on the biomass differing from those on the litter and soil. Our results demonstrate the importance of accounting for all forest carbon pools to avoid misleading pictures of short-and long-term forest carbon balance.carbon inventory / forest biomass / greenhouse gas inventory / litter / soil modelling Résumé -Accumulation de carbone dans les forêts finlandaises entre 1922 et 2004, une estimation obtenue en combinant les données de l'inventaire forestier avec une modélisation de la biomasse de la litière et du sol. Une estimation comparable à l'échelle régionale du bilan de carbone des forêts était nécessaire pour des objectifs scientifiques et politiques. Nous avons développé une méthode pour déduire ces estimations de données facilement disponibles de l'inventaire forestier en utilisant des modèles statistique de la biomasse et une modélisation dynamique de la litière et du sol. Ici nous présentons cette méthode et l'appliquons aux forêts de Finlande entre 1922 et 2004. La méthode a été fiable, puisque les résultats obtenus ont été comparables à des données indépendantes. La quantité de carbone accumulée dans les forêts s'est accrue de 29 %,79 % de ce qui a été trouvé dans la biomasse et 21 % dans la litière et le sol. Le bilan de carbone varie annuellement, selon le climat et l'importance de la récolte, chacun de ces facteurs ayant des effets sur la biomasse différents de ceux qui agissent sur la litière et sur le sol. Nos résultats démontrent l'importance de comptabiliser tous les réservoirs de carbone en forêt pour éviter des images trompeuses du bilan de carbone des forêts à court et moyen terme.inventaire du carbone / biomasse forestière / inventaire des gaz à effet de serre / litière / sol

“…Among the most notable contributions of mosses are their capacity to support diverse, multitrophic, biological communities (Lindo & Gonzalez, 2010), influence nitrogen and phosphorus cycling at a landscape scale (Chapin III et al, 1987;Turetsky, 2003;Cornelissen et al, 2007;Rousk et al, 2014), augment abiotic soil conditions such as moisture, temperature, and redox potential , and make significant contributions to net primary productivity in many terrestrial systems (Longton, 1992;Gornall et al, 2007;Blok et al, 2011;Rousk et al, 2014). The role of mosses in global change biology is perhaps best documented in peatland systems where the genus Sphagnum dominates and is responsible for the storage of more than one third of the worlds terrestrial carbon (Loisel et al, 2012).…”

Sex-Specific Fungal Communities of the Dioicous Moss Ceratodon purpureus

Mosses display a number of hallmark life history traits that influence their ecology at the population and community level. The long lived separation of sexes observed in the haploid gametophyte (dioicy) is one such feature of particular importance, as it is observed in the majority of bryophytes and creates intraspecific specialization of male and female individuals.The prevalence of sexually dimorphic mosses raises the possibility of sex-specific interactions with fungi as observed in some vascular plants. Here I investigated how moss sex shapes fungal communities associated with gametophytic tissues of the ubiquitous moss, Ceratodon purpureus. Using greenhouse populations of C. purpureus grown in a common garden, I examined fungal community structure and overall abundance of fungal biomass associated with male and female individuals from multiple populations. I hypothesized that individual mosses would harbor unique fungal communities based on their sex, and that overall fungal biomass associated with host tissues would differ significantly due to differences in morphological and physiological characteristics between the sexes. I found that fungal community composition and overall abundance (i.e. biomass) differ between male and female individuals of C. purpureus, and that sex-specific patterns are retained across individuals from three different populations. This work provides a first glance at how genetically based sexual systems in early land plants influence affiliated fungal community composition.ii Acknowledgments

“…Bryophytes exhibit a high level of diversity and often form a conspicuous and important component in many terrestrial ecosystems throughout the world (Longton, 1984). Following angiosperms, they are the most diverse group of plants in the world: ~ 5,000 species of liverworts, 13,000 species of mosses and 150 species of hornworts (Crandall-Stotler et al, 2009;Goffinet et al, 2009;Renzaglia et al, 2009).…”

Bryophytes (liverworts, mosses and hornworts) are the closest living relatives of the first group of plants that successfully colonized land. This small but well-established group of plants is unique among other land plants in having a dominant gametophyte phase in their life cycle and a single unbranched sporophyte that depends on the dominant gametophyte plant. Bryophytes occur throughout the world in all continents, occupying an assortment of habitats, especially in moist shady places. Many species have broad geographic ranges that may span two or more continents. Dispersal of bryophytes is brought about by spores, vegetative propagules or by unspecialized fragments of the gametophyte.The bryophyte flora of Sri Lanka remains relatively poorly researched. According to checklists available, the Island harbours 560 mosses, 327 liverworts and five hornworts. Most of the collecting has been in the southern half of the country, especially in the Central Highlands. Exact locality details are missing for most of these specimens. There is no documentation for moss or liverwort Flora of Sri Lanka. Lack of a thorough taxonomic foundation is a major impediment to study the biogeography of Sri Lankan bryophytes. O'Shea (2003) presented a summary of current knowledge of biogeography of Sri Lankan mosses. According to his statistical analysis based on existing records Sri Lankan mosses show strong relationships with India, Indochina, and Malaysia but a much lower affinity with Africa.Here we conducted a similar study for liverworts and hornworts using Kroeber's percentage of similarity, which suggests that Sri Lankan liverworts and hornworts show a considerable similarity with those of Java, Malaysia, Thailand, and India. However, more and wider systematic field explorations and taxonomic studies are needed to understand the biogeography of Sri Lankan bryophytes. To address this, field explorations and phylogenetic studies are being carried out, and the results will contribute to elucidate the biogeographic affinities of Sri Lanka's bryophyte flora.
