In order to understand how communities of rock-inhabiting micro-organisms are spatially organized, rock samples and environmental variables were collected from five cliff sites in Ontario, Canada. Algae and cyanobacteria were extracted from the epili

Thuja occidentalis is the dominant tree of ancient, stunted cliff‐face forests of the Niagara Escarpment, Ontario, Canada, and in Michigan and Wisconsin, U.S.A. Previous field research has shown that nutrient and water limitations at the sapling st

Thuja occidentalis shows slow growth, strip-bark morphology, and extreme longevity when growing on cliffs of the Niagara Escarpment, Ontario, Canada. To test whether these features could result from sectored radial architecture, dye-infusion experime

Cliffs of the Niagara Escarpment, southern Ontario, Canada support a presettlement forest of stunted, long-lived, and grossly deformed Thuja occidentalis showing pronounced strip-bark growth. Previous studies had suggested that longevity and axis asy

This study was carried out to determine if the desiccation-tolerant fernPolypodium virgimanum L. ecologically resembles lower plants by absorbing atmospheric water through its fronds and actively growing in early spring when the soil along cliff edge

Thuja occidentalis L. and Acer saccharum Marsh, show mutually exclusive distribution patterns along forested cliff edges of the Niagara Escarpment; T. occidentalis occurs at the cliff edge and on the cliff face, whereas A. saccharum occurs with incre

The effects of both seed source and fungal species on the formation of beads in roots of Piceamariana (Mill.) B.S.P. were examined. Seed was collected from two sites near Chapleau, Ontario. One provenance was an upland site with sandy soil, the secon

In cliff-edge forests along the Niagara Escarpment, an array of species, including Thuja occidentals, is restricted to the cliff edge while different species, including Acer saccharum, are increasingly dominant away from the cliff on the plateau. Thi
