Thirty-nine moss species occur on Kent Island, New Brunswick. Two-thirds of the moss species found on the island have mainly boreal ranges, which reflects the cool growing season and generally boreal character of the Bay of Fundy's vegetation. One species, Rhytidiadelphus loreus, has been recorded only once previously in the province. Most moss species showed distinctive habitat distributions. ...

Mosses (Musci, Bryophytaea) are one of the oldest groups of land plants present among the earth’s flora. They originated 500 million years ago (for a recent discussion of the time scale involved, see Heckman et al., 2001) and are currently represented by approximately 10,000 species that colonize diverse habitats that range from high mountains to deep forests and from Antarctica to deserts. Evo...

Unlike animals, which produce single-celled gametes directly from meiotic products, plants have generations which alternate between the diploid sporophyte and haploid gametophyte (Figure 1A). The diploid sporophytic generation develops from the zygote, the fusion product of haploid gametes. Sporophytic cells undergo meiosis to produce haploid spores, which divide mitotically to form the multice...

Introduction Glacial refugia have likely been important in shaping diversity gradients outside the tropics. Many taxa that high extratropical present day, such as mosses, may persisted glacial refugia. However, biogeographical histories of most species within remain unclear. Location Haida Gwaii archipelago, north-west coast British Columbia, Canada. Taxa Bryophyta (mosses). Methods We reconstr...

In 2004, we surveyed the vegetation on Mount St. Helens to document changes since 1992. We asked how communities differentiate and if they develop predictable relationships with local environments. We sought evidence from links between species and environment and changes in community structure in 271 250-m(2) plots. The habitats of the seven community types (CTs) overlapped broadly. Ordination ...
