  2. 1. Grasslands in a changing climate : Summer drought and winter warming effects on grassland vegetation

    Author : Nina Roth; Sara A. O. Cousins; Carly Stevens; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biodiversity; climate change; compost; floral resources; grasslands; in-situ experiments; mowing; nectar; open-top chambers; plants; rain-out shelters; sheep grazing; soil amendments; summer drought; winter warming; naturgeografi; Physical Geography;

    Abstract : Grasslands harbour a high biodiversity of both plants and animals, and they provide many ecosystem services such as fodder production, pollination, and carbon storage. Climate change is likely to alter grassland ecosystems, with the effects varying according to the exact nature and timing of changes. READ MORE

  4. 2. Climate change impacts on aquatic consumer communities

    Author : Shuntaro Koizumi; Pär Byström; Ryan Sponseller; Jonathan Shurin; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; warming; browning; aquatic consumers; zooplankton; benthic insects; fish; ecosystem experiment; environmental science; miljövetenskap;

    Abstract : Climate change represents a serious threat to aquatic ecosystems, with an increase in lake temperatures already observed that is expected to continue in the near future. Aside from the direct effects of warming, climate change is also partially responsible for the browning of lakes. READ MORE

  5. 3. Climate Change sensitivity of Photosynthesis and Respiration in Tropical Trees

    Author : Myriam Mujawamariya; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon dioxide; Climate change; Drought; Elevation gradient; Photosynthesis; Respiration; Tropical montane forest; Tropical trees; Warming;

    Abstract : Tropical climate is getting warmer, with more pronounced dry periods in large areas. The productivity and climate feedbacks of future tropical forests depend on the ability of trees to acclimate their physiological processes, such as photosynthesis and leaf respiration, to these new conditions.

  6. 4. Uncertainties in tropical precipitation and radiative feedbacks under climate change

    Author : Alejandro Uribe Cortes; Thorsten Mauritsen; Frida Bender; Caroline Muller; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Climate change; radiative feedback; tropical precipitation; tropical extreme precipitation; climate modeling; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Abstract : Clouds have a significant impact on climate. They contribute to controlling the planetary energy balance, and the precipitation distribution. Global Climate Models (GCMs) designed to reproduce the state of the climate system, however, have difficulties representing clouds. READ MORE

  7. 5. Atmospheric & Oceanic Applications of Eulerian and Lagrangian Transport Modelling

    Author : Joakim Kjellsson; Kristofer Döös; Jonas Nycander; Joseph LaCasce; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Eulerian; Lagrangian; trajectory; climate; atmosphere; ocean; modelling; drifter; thermodynamic; climate change; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : This thesis presents several ways to understand transports of air and water masses in the atmosphere and ocean, and the transports of energy that they imply. It presents work using various kinds of observations as well as computer simulations of the atmosphere and oceans. READ MORE
