A biotic agent promotes large‐scale catastrophic change in the coastal marshes of Hudson Bay
Summary 1 Herbivores may initiate small changes to plant–soil systems that trigger positive feedbacks leading to rapid catastrophic shifts in vegetative states, including irreversible changesExpand
Prediction of reproductive success and failure in lesser snow geese based on early season climatic variables
Both the multiple regression analyses and the redundancy analyses confirm the high degree of predictability of goose reproductive variables from selected climatic variables. Expand
Soil microbial and nutrient dynamics in a wet Arctic sedge meadow in late winter and early spring
Abstract Microbial activity is known to continue during the winter months in cold alpine and Arctic soils often resulting in high microbial biomass. Complex soil nutrient dynamics characterize theExpand
The Effects of Grazing by Lesser Snow Geese on the Vegetation of a Sub- Arctic Salt Marsh
Les resultats obtenus dans un marais domine par Puccinellia phryganodes et Carex subspathacea a La Perouse Bay (Canada) suggerent que le pâturage stimule la production primaire en accelerant le cycleExpand
Increases in the net above-ground primary production of a salt marsh forage grass: a test of the predictions of the herbivore-optimization model.
The effects of grazing by captive goslings of the lesser snow goose on the vegetation of the La Perouse Bay salt marsh were investigated. On seven separate occasions during the summers of 1986 andExpand
Vertebrate Herbivores and Northern Plant Communities: Reciprocal Influences and Responses
Overall, herbivores do not appear to influence plant species assemblages in the different communities in the long term or alter the trajectory of plant succession at the landscape level, but they may have considerable short-term effects on vegetation, particularly at fine spatial scales (1-20 m). Expand
The dynamics of landscape change and snow geese in mid‐continent North America
The Mid-Continent Population of the lesser snow goose, which breeds in the eastern and central Canadian Arctic and sub-Arctic, and winters in the southern United States and northern Mexico hasExpand
Arctic ecosystems in a changing climate : an ecophysiological perspective
F.S. Chapin III, R.L. Jefferies, J.F. Reynolds, G.R. Shaver, and J. Svoboda, Arctic Plant Physiological Ecology: A Challenge for the Future. The Arctic System: B. Maxwell, Arctic Climate: PotentialExpand
Destruction of wetland habitats by lesser snow geese: a keystone species on the west coast of Hudson Bay.
SUMMARY (1) Large numbers of lesser snow geese breed in colonies in coastal brackish and freshwater marshes in the lowlands along the west coast of Hudson Bay. Where colonies are present, the geeseExpand
Saltmarsh erosion and restoration in south-east England: squeezing the evidence requires realignment: Saltmarsh erosion and restoration
A literature review of physical and biological processes relevant to saltmarsh erosion and the combination of strong winds, high tides and increased wave height appears to be responsible for the increased rate of marsh erosion and creek dissection recorded in the 1970s. Expand
