“…The often conspicuous presence of spores of coprophilous fungi in peat and lake sediments is usually explained by concomitant influx of dung of large herbivores, wild or domesticated (Pals et al 1980, Van Geel et al 1981, 1983, Witte 6r Van Geel 1985, Davis et al 1977, 1984.…”

“…The complement of spores recovered from lake and peat sediments is, in general, limited in number and diversity, and rather constant in composition as far as the representative morphological spore-types or even taxa are concerned. This no longer surprises (Wolf 19660) in the light of evidence that spores in lake sediments are derived from fungi associated with local, lake-side rather than regional vegetation (Wolf 19676, 1967c;Witte & Van Geel 1985), and that those in peats largely represent fungi growing on peat bog vegetation as saprobes or weak parasites ( Van Geel 1978). Dcspite all appearances, the spores of most fungi do not blow around in the wind but rather depend on less haphazard agencies of dispersal.…”

“…According to a palaeoecological study of pollen and peat deposits, the swamps of the Dutch coastal region were dominated by P. australis from around 4500 BP until approximately 800 BP, when the area became less eutrophic (Witte and van Geel 1985).…”

-common reed, is a perennial, emergent aquatic plant with annual cane-like stems developed from an extensive rhizome system. It grows in low-lying wet areas such as fresh and salt-water marshes, drainage ditches, shallow lake edges, sandy banks, roadsides, woodlands and rocky places. Stems can reach up to 6.0 m in height, vary in diameter from 4 to10 mm and have 10 to 25 cm long hollow internodes. Clones are extended by perennial rhizomes with extensive aerenchymatous tissue that supplies oxygen. Roots develop from rhizomes and other submerged parts of shoots. Leaves are smooth, alternate with narrow-lanceolate laminae, 20 to 70 cm long and 1 to 5 cm broad, and tapering to long slender points. The inflorescence is a terminal panicle, often 30 cm long, dull purple to yellow, with main branches bearing many spikelets. Seed production and germination are extremely variable and comparatively rare in many populations. Phragmites australis carries out photosynthesis through the C 3 pathway (or a variation thereof). Studies of genetic variation through isozyme and other molecular methods suggest that the populations are very closely related, and that variation in the metapopulation is small. Chloroplast DNA sequences of two non-coding regions indicate that non-native introduced genotypes of P. australis have displaced native genotypes in parts of North America. Phragmites australis often forms extensive monocultures in North America. As a consequence, habitat quality and species diversity have been documented to decline. However, in roadside populations it is effective in taking up many typical heavy metals that originate from nearby highways and buildings. Phragmites australis is found in all Canadian provinces and the Northwest Territories, but not in the Yukon Territory or Nunavut. The infestation of P. australis is most severe in the Great Lakes region and its migration is primarily mediated through rivers, canals and waterways but roadways are increasingly becoming important. Changes in the water regime have been linked to its success and could ultimately result in changes to the floristic composition of a habitat. Rodeo™, an aqueous solution of the isopropylamine salt of glyphosate, is most frequently used to control P. australis populations. Other methods of control include cutting, burning, and drainage of the species' habitat. As P. australis is considered to be invasive in North America, introduction of biological control agents is now being investigated. Can. J. Plant Sci. 84: 365-396. Le roseau commun Phragmites australis (Cav.) Trin. ex Steud. est une vivace aquatique dont le vaste système de rhizomes donne chaque année des tiges ressemblant à des cannes. L'espèce pousse dans les dépressions humides comme les marais d'eau douce et salants, les fossés de drainage, la rive des lacs peu profonds, les berges sablonneuses, le bord des routes, les boisés et les endroits rocailleux. Les tiges atteignent parfois jusqu'à 6,0 m de hauteur et leur diamètre varie de 4 à 10 mm, avec de longues sections creuses de 10 à ...

“…Les concentrations polliniques (grains/cm 3 ) furent calculées par l'ajout d'un volume connu d'une suspension de pollen d'Eucalyptus globulus de concentration connue (Benninghoff, 1962). Les concentrations polliniques des taxons extra-tourbicoles furent calculées séparément afin de retracer des fluctuations du rythme d'accumulation sédimentaire net de la tourbe, de fortes concentrations polliniques pouvant signifier un ralentissement du rythme d'accumulation, et vice-versa (Middeldorp, 1982 ;Witte et Van Geel, 1985). Lorsqu'ils étaient présents, les rhizopodes et les rotifères furent identifiés sur les mêmes préparations microscopiques que celles utilisées pour le dénombrement du pollen et des spores.…”
