  1. 1. Swedish seagrass ecosystems in a changing climate Coastal connectivity and global change sensitivity

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

    Author : Diana Perry; Martin Gullström; Jason Hall-Spencer; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; coastal seascape; shallow-water ecosystems; fish assemblages; connectivity; global change; climate change; multiple stressors; seagrass; Zostera marina; temperate region; marin ekologi; Marine Ecology;

    Abstract : Coastal shallow-water ecosystems are essential for providing several goods and services globally, with seagrasses as an important contributor for maintaining high biodiversity and productivity within the nearshore seascape. The temperate species Zostera marina serves as a vital habitat for many species, including ecologically and economically important juvenile fish. READ MORE

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

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

    Author : Rushingisha George; Mats Björk; Martin Gullström; Teresa Alcoverro Pedrola; [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

  3. 3. Developmental switches in a family of temperate phages

    University dissertation from Stockholm : Institutionen för genetik, mikrobiologi och toxikologi

    Author : Alexandra Ahlgren Berg; Elisabeth Haggård-Ljungquist; Gianni Dehò; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology Cell and molecular biology Genetics; NATURVETENSKAP Biologi Cell- och molekylärbiologi Genetik;

    Abstract : P2 is the prototype phage of the non-lambdoid P2 family of temperate phages. A developmental switch determines whether a temperate phage will grow lytically or form lysogeny after infection. P2 related phages have two face-to-face located promoters controlling the lysogenic and the lytic operon respectively, and two repressors. READ MORE

  4. 4. The long-term history of temperate broadleaves in southern Sweden

    University dissertation from ; Southern Swedish Forest Research Centre, Swedish University of Agricultural Sciences

    Author : Tove Hultberg; Sveriges lantbruksuniversitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Temperate broadleaves used to be abundant in the primeval forests in southern Sweden, yet today they cover only fractions of the forest land. Considering the present small area of the forest type, the habitat is of considerable interest for biodiversity, and knowledge about the history of temperate broadleaves is crucial for forest conservation and management.

  5. 5. Old-Growth Forests in the High Coast Region in Sweden and Active Management in Forest Set-Asides

    University dissertation from Sundsvall : Mid Sweden University

    Author : Jennie Sandström; Bengt-Gunnar Jonsson; Mattias Edman; Mikael Ohlson; [2018]

    Abstract : In today´s intensively managed landscape, very few forests with old-growth characteristics and little human impact exist. One of the rare exceptions is pine forests on rocky soils, a forest type which has probably escaped extensive human use because of its low productivity. READ MORE
