Carbon and nitrogen fluxes associated to marine and estuarine phytoplankton
(2018-05-14)Globally, mainly nitrogen or phosphorus is limiting the primary production. New nitrogen can enter estuarine ecosystems as nitrate from upwelling events, from river runoff, atmospheric deposition, or by nitrogen fixation. ... -
Dispersal of Microalgae- the role of Biological and Physical Barriers
(2015-09-04)Microalgae are only a few micrometres to a millimetre in size, yet they constitute the base for aquatic food webs and are extremely important drivers in elemental cycling. Long it has been assumed that small organisms (<1 ... -
Evolutionary and Ecological Effects of Metal Pollution on Coastal Diatoms
(2022-10-21)Oceans are changing rapidly in response to human activities, such as toxic pollution, eutrophication, and climate change. Diatoms are major primary producers in the oceans with short generation times, flexible reproductive ... -
From Sea to Society - Climate Change, Microbial Community Interactions and Assessing Climate Risk on Society
(2017-11-11)Unicellular organisms, microalgae and bacteria, less than one millimeter in size make the world go round. Phytoplankton and cyanobacteria, for example, plays an inevitable role contributing 50-85% to the world’s oxygen ... -
Genetic structuring in natural populations - the influence of life history strategies and asymmetric migration
(2016-09-09)In this thesis I investigate aspects of genetic differentiation and factors influencing the structure of populations. This is done with a special focus on life histories and dispersal strategies common in the marine ...
