    Coastal Marine Eutrophication

    Eutrophication is a complex process that turns low-nutrient, clear water sea to a murky, high-nutrient sea. Marine eutrophication processes differ from lakes due to the open physical structure of the sea, higher diversity of biotic habitats and more ... Read More

    Common pool resource harvesting

    A community derives ecosystem services by extracting from a renewable resource such as water, fish, or forest. If a harvester is overharvesting (a defector), he/she is ostracised by the community, for example by obstructing their access to necessary ... Read More

    Mangrove transitions

    Mangroves are ecosystems adapted to the mixture of salt and fresh water in coastal areas. They provide important ecosystem services such as carbon storage, storm protection, ground fields for several marine species, water cleansing, and wood for cons ... Read More

    Fisheries collapse

    A fishery collapses when the structure of the marine community (i.e. its species composition) changes radically, trapping the fishery into a regime in which high-valued commercial species cannot recover. These dynamics are often characterized by casc ... Read More

    Marine food webs

    A characteristic regime shift in aquatic systems involves an abrupt increase in the dominance of lower trophic level groups within aquatic food webs. This regime shift involves a change from an ecosystem with high numbers of predatory fish to one dom ... Read More

    Coniferous to deciduous boreal forest

    This regime shift has been well studied in the interior Alaska where the coniferous dominated boreal forest are being replaced by deciduous trees due to recent climate warming and changes in the wildlife regime. Coniferous trees thrive in cold, ... Read More

    Thermokarst lake to terrestrial ecosystem

    Thermokarst lake dominated landscapes are transforming into terrestrial ecosystems (e.g.: tundra). There is a natural fluctuation between these two ecosystems. However, the rate and scale at which those fluctuations are occurring are increasing due t ... Read More

    Steppe to Tundra

    Steppe (a grassland) to tundra (mosses and shrubs growing in waterlogged soils) is a regime shift that can occur in cold terrestrial ecosystems.  Tundra and steppe regime shift is typically found where permafrost occurs.  Steppe and tundra ... Read More
