All samples of aquatic bryophytes had detectable concentrations of Cd, Cu, Pb and Zn. The greatest diversity is at tropical and subtropical latitudes. Principal components analysis of chemical and physical properties classified sites into three groups. The Irish aquatic macrophyte communities have some unique attri-butes, for example, the high representation of bryophyte flora. Aquatic Bryophytes Heather Lintz Botany and Plant Pathology Oregon State University I. We explored the relationship between aquatic bryophytes and fine sediment cover, and their relative importance to biological communities (leaf-decaying fungi, diatoms, macroinvertebrates) and leaf breakdown rate in boreal headwater streams. Periphyton was scraped from artificial substrata placed 2 months previously at the open site (Suren 1990).
In: Glime, J. M. Bryophyte Ecology. Aquatic bryophytes are used to assess the ecological status. Big picture What is a bryophyteWhat is a bryophyte? They are a stress-tolerant group, and many species have a wide trophic range. Amongst these were three lakes where bryophytes were recorded at greater than 50 m depth, with a reported depth of 65 m for Lake Geneva (Switzerland), 120 m for Crater Lake (United States), and … sity of Illinois bryophytes and the variety of microhabitats in which they grow.
Bryophytes (especially the moss Sphagnum) dominate the vegetation of peatland in extensive areas …
Aquatic insects: Bryophyte roles as habitats. Bryophyte Examples The three main types of bryophytes consist of the liverworts, mosses, and hornworts, each of which encompasses several hundred different species. Chapt. Bryological Interaction. * Text words inbold are defined in the glossary.
Bryophytes are most abundant in climates that are constantly humid and equable. Volume 2, Chapter 11-2: Aquatic Insects: Bryophyte Roles as Habitats. Biology-Life Cycle-Major Groups-Adaptations III. Aquatic vegetation classification systems elsewhere rarely consider bryophytes in a comprehensive manner but instead focus mainly on the vascu-lar plant composition (e.g., Rodwell et al., 1995; Chytrý et al., 2011; Examples of important genera would be Drepanocladus, Hamatocaulis, Warnstorfia, Meesia, Campylium, Calliergon, and Scorpidium. True mosses dominate the ground layer of rich fens, especially a series of species that are red-brown in color and often termed ‘brown mosses’. Glime, J. M. 2017. The most significant of the bog bryophytes are the mosses in the genus Sphagnum. II. The distribution of bryophyte assemblages included lakes from Antarctica, Western Europe, United Kingdom, South-East Asia, and both North and South America. of beech (Nothofagus), and samples of trapped benthic detritus were taken from the shaded site. 11-2. The major conservation concern for bryophytes is loss of microhabitat diversity. permanently aquatic environments. Alpha radioactivity was found to bear an inverse relationship to the uranium content of many bryophytes. Sphagnum bogs are estimated to cover between 1% and 2% of the world's land surface (more than the area covered by any other single plant genus) and have significant ecological roles. Aquatic bryophytes growing in streams were used for biogeo- chemical prospecting for uranium in the Buller Gorge area of New Zealand. Aquatic bryophytes as ecological indicators of the water quality status in the Tiber River basin (Italy)
Aquatic Bryophytes as Indicators of Uranium Mineralization' NEIL E. WHITEHEAD AND ROBERT R. BROOKS2 Abstract. A few bryophytes are aquatic. Places such as streams, lakes and bogs are home to many species of bryophytes.
