“…My results corroborate the significance of the relationship between species composition and the water depth gradient in wetlands (Graham and Henry 1933;Hutchinson 1975;Keddy 1983Keddy , 1984aKeddy , 1984bKeddy and Constabel 1986;Keddy and Ellis 1985;Seabloom et al 1998;Spence 1982;Wilson and Keddy 1985) and in coastal plain ponds (Zaremba and Lamont 1993). Elevation along the water-depth gradient was the only local-scale environmental variable within the boundaries of a coastal plain 208 Rhodora [Vol.…”

“…Early lakeshore studies observed that the water-depth gradient provides the most obvious correlation with the formation of sequenced communities, also referred to as coenoclines (Graham and Henry 1933;Hutchinson 1975;Spence 1982). Researchers have since demonstrated that water depth affects seedling community composition along lakeshores (Keddy and Constabel 1986;Keddy and Ellis 1985), and species richness and stem density in prairie wetlands (Seabloom et al 1998).…”

“…This successional development of the coastal environment ultimately climaxes in salt-marsh systems, unless harsh hydrodynamic conditions prevent the peat accumulation necessary for marsh development. Such an interface between successional species interactions and environmental limitations can lead to 'arrested succession', which is succession terminated by local environmental circumstances (Graham & Henry 1933). In our study system, the hydrodynamic conditions along the environmental gradient effectively determine prevailing species interactions, which combine with positive feedbacks to generate distinct habitats from a common pool of potential component species.…”

Though species interactions across local environmental gradients are well studied, the way in which species interactions shift between different habitats on a landscape scale has received less attention. We hypothesised that interactions among a suite of shoreline plant species shift across a hydrodynamic-exposure gradient, leading to generation of apparently distinct habitat types (e.g. bare cobble beaches, vegetated cobble beaches, fringing marshes and salt marshes). We examined hydrodynamic forcing and found that it was strongly correlated with shoreline habitat type. A transplant experiment revealed that all plants were rapidly crushed and abraded in bare cobble areas with high hydrodynamic energy and were out-competed by grasses in the low-energy salt marshes. Vegetated cobble beaches are inhabited by the largest amount of plant species under intermediate conditions, where hydrodynamic energy is sufficiently low to allow the establishment of the ecosystem engineer Spartina and sufficiently high to prevent the monopolisation of space by competitively dominant, but stress intolerant grasses. Experimentally reducing physical and biotic stresses (hydrodynamics and interspecific competition) on bare cobble beaches and salt marshes, respectively, enabled forbs to persist across the whole gradient. These results demonstrate that the outcome of interspecific interactions at landscape scales is driven by background physical conditions, and that this can result in the development of what are considered distinct habitats.

Les platières sont des tabliers organo-minéraux occupant la rive de plusieurs grands lacs de la toundra forestière du Québec. La végétation qu'elles portent est périodiquement affectée par l'activité des vagues et les poussées glacielles. Le maintien de ces végétaux dans des habitats hautement dynamiques soulève plusieurs questions d'intérêt écologique et géomorphologique qui ont été étudiées au lac à l'Eau Claire, en Hudsonie. Les platières comportent une mosaïque de parcelles végétales en voie de régression ou de croissance, selon l'exposition aux perturbations allogènes. Bien qu'il existe un étagement des espèces en fonction du gradient d'immersion et d'exposition, la zonation en bandes subparallèles à la rive habituellement observée en périphérie des lacs tempérés, est ici peu prononcée. On trouve la diversité floristique optimale dans des sites présentant des conditions intermédiaires d'exposition où le bilan sédimentaire est très variable. Le développement des platières en région subarctique est stimulé par des fluctuations très irrégulières du niveau lacustre d'une année à l'autre, probablement en réponse aux variations interannuelles des précipitations de neige. La dénivellation du plan d'eau au cours de la saison de végétation influence l'intensité de l'activité géomorphologique des glaces et des vagues sur les rives et détermine ainsi les modalités de la succession écologique.Around most large lakes of the forest tundra zone in Québec, vegetation colonizes sheltered shores periodically affected by storm waves and ice pushes. Many questions of ecological and geomorphological interest arise from the existence of these vegetation forms within particularly dynamic habitats. In the Lac à l'Eau Claire area, vegetated platforms comprise a mosaic of regressive and progressive mats, resulting from exposure to varying degrees of geomorphic disturbance and prolonged drowning. The species occupy different vertical positions according to immersion and exposure gradients, but zonation patterns parallel to the shoreline, typical of other regions are uncommon here. Species richness is highest in intermediate disturbance conditions, that is along shores where the sedimentary environment is most unstable. Water level during growth period controls the position reached by ice-pushes and waves along the shores and affect the plant succession process. Water level changes from year to year are probably caused by annual variations in snow fall amounts.Am Ufer von mehreren grossen Seen der Wald-Tundra Québecs befinden sich organisch-mineralische Plattformen.
