  1. 1. Seagrasses in warming oceans physiological and biogeochemical responses

    University dissertation from Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : Rushingisha George; Stockholms universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Global warming; greenhouse gas; warming oceans; temperate; tropical; coastal waters; Western Indian Ocean WIO ; tidal variability; seagrass; photosynthesis; respiration; photorespiration; biogeochemical processes; sulphide; methane; nitrous oxide; carbon dioxide; växtfysiologi; Plant Physiology;

    Abstract : The exponential increase of atmospheric greenhouse gas concentrations over the past 50 years has caused a rise in the global average temperature by more than 1ºC above pre-industrial levels. Ninety-three percent of this heat energy has been absorbed and stored by the oceans, increasing their temperatures, particularly in surface waters. READ MORE

  2. 2. Effects of warming and browning on benthic and pelagic ecosystem components in shallow lakes

    University dissertation from Umeå : Umeå Universitet

    Author : Francisco Rivera Vasconcelos; Umeå universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; benthic; pelagic; algae; consumers; browning; warming; shallow lakes; food web; dissolved organic matter;

    Abstract : The majority of lakes on Earth are shallow, unproductive and located at high latitudes. These lakes are experiencing big changes due to climate change, where two environmental drivers operate simultaneously, browning and warming. How they affect lake ecosystems is not well understood.

  3. 3. Effects of warming on the ecology of algal-dominated phytobenthic communities in the Baltic Sea

    University dissertation from Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : Filip Svensson; Stockholms universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; climate change; warming; photosynthesis; trophic cascades; pigments; community traits; temperature gradient; invasive mussel; marin ekologi; Marine Ecology;

    Abstract : Through climate change, the global average air and surface water temperature has risen 0.85°C during the last 100 years. The Baltic Sea experienced one of the most rapid increase in temperature recorded of marine ecosystems. READ MORE

  4. 4. Effects of warming and nutrient enrichment on feeding behavior, population stability and persistence of consumers and their resources

    University dissertation from Umeå : Umeå University

    Author : Wojciech Uszko; Umeå universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; consumer-resource; Daphnia; functional response; nutrient enrichment; parameter estimation; persistence; plankton; predator-prey; stability; temperature; type II; type III; warming;

    Abstract : Consumer-resource interactions are the basic building blocks of every food web. In spite of being a central research theme of longstanding interest in ecology, the mechanisms governing the stability and persistence of consumer-resource interactions are still not entirely understood.

  5. 5. Global Warming and Our Natural Duties of Justice A cosmopolitan political conception of justice

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Aaron Maltais; Uppsala universitet.; [2008]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Political science; Global warming; climate change; global justice; natural duties; political conception; contractualism; intergenerational; political duty; political authority; collective action; public goods; John Rawls; Thomas Nagel; Statsvetenskap; SOCIAL SCIENCES Social sciences Political science; SAMHÄLLSVETENSKAP Socialvetenskap Statsvetenskap; Statskunskap; Political Science;

    Abstract : Compelling research in international relations and international political economy on global warming suggests that one part of any meaningful effort to radically reverse current trends of increasing green house gas (GHG) emissions is shared policies among states that generate costs for such emissions in many if not most of the world’s regions. Effectively employing such policies involves gaining much more extensive global commitments and developing much stronger compliance mechanism than those currently found in the Kyoto Protocol.
