The title of my PhD project, which I started in November 2010, is "Trees, carbon and groundwater: trade-off or synergy for water resources in the semi-arid tropics". The main aim is to reveal the conditions under which increased tree cover leads to both higher carbon storage and better adaptative capacity to climate change, particularly groundwater recharge, in the semiarid tropics. The field-work of the project is conducted in a Vitellaria paradoxa (shea-butter tree) parkland in central Burkina Faso.

I am holding a MSc degree with a major in Soil Science from the Swedish University of Agricultural Sciences (SLU) and a Msc in Forestry from Universitat de Lleida, Spain.

Master thesis: Water infiltration in the Nyando River basin, Kenya.

Supervisors
My main supervisor is Ulrik Ilstedt. Assistant supervisors are Anders Malmer, Hjalmar Laudon and Gert Nyberg

Berg_A_webb"Sami forest use and industrial forestry - coexsistence, resource use and conflicts 1800-2000" is the title of my PhD project. I study how the reindeer herders in northern Sweden have used the forest before the middle of the 19th century when modern forestry was introduced in the area, and how modern forestry have affected the reindeer herders since then. Lars Östlund is my supervisor.

I am a PhD-student interested in the carbon balance of mires. My research focuses on the exchange of greenhouse gases between the mire and the atmosphere and carbon exported in the mire discharge. The research is conducted at a mire with one of the longest complete year data records on CO2 net ecosystem exchange in the world, Degerö Stormyr, situated about 70 kilometres from the city of Umeå, northern Sweden. The main objective of my research is to understand what major factors control the net carbon exchange of this boreal oligotrophic minerogenic mire. I am especially interested in the major carbon exchange routes during the different seasons of the year and how weather conditions affect the exchange routes.

Stuiver_B_webbI started my PhD in February 2011. My PhD topic is the "Effect of understory vegetation on forest regeneration and response to disturbance".

I will be looking at the way the understory vegetation affects the regeneration of four coniferous tree species (pine, spruce, larch and contorta pine), with focus on the mosses and dwarf-shrubs. Both positive and negative effects are of interest. When is there a window of opportunity for the regeneration of the previous named tree species?
The first experiment is planning to be situated along a fire disturbance gradient in northern Sweden.

We will also expand the research to production forests.

Previously I have been working for the Swedish Forest Agency.

My supervirsor is Marie-Charlotte Nilsson Hegethorn.
Co-supervisors are David Wardle and Michael Gundale.

erhagen_b_webbI was born in the beautiful city of Örebro, and moved up to Umeå in 2003 for my undergraduate studies. I am holding a Master of Science with a major in soil science from SLU, Umeå. My PhD project; Temperature control of microbial turnover of organic carbon at SLU started in January 2008.

The focus of my research is to specify how the degradation of soil organic matter in the boreal forest is influenced by possible temperature changes as, e.g. by increasing air and soil temperatures due to climate change.

I have recently completed my PhD working with David Wardle and Marie-Charlotte Nilsson in the Department of Forest Ecology and Management and in collaboration with Duane Peltzer in New Zealand.
My PhD thesis is titled: Regulation of litter decomposition and nutrient availability in Swedish and New Zealand forest ecosystems. Acta Universitatis Agriculturae Sueciae 2012:96
This research has involved conducting field and laboratory based investigations examining how plant species and plant functional traits influence the decomposition of plant litter. My work is divided between two study systems, the boreal forests in northern Sweden and the temperate rainforests on the west coast of New Zealand.

bay_gI am a PhD student since August 2008 and I am working on the role of nitrogen fixing cyanobacteria in feather mosses on nitrogen input to boreal forest ecosystems.
This PhD is focusing on the biodiversity of cyanobacteria living within three different mosses found in boreal forest, about the diversity of cyanobacteria and the rate of nitrogen fixation performed by these bacteria in the field and in the lab, as well as how the composition of cyanobacteria living in association with mosses affect the resistance and resilience of nitrogen fixation to external perturbations.

I am a PhD student with SLU since 2009. I am holding a Diplom (Msc) in Hydrology from the University of Freiburg, Germany. My recent work is mainly focusing on the impact of forestry on hydrology and water quality in streams of the boreal landscape.

A major part of my research is conducted to the 'Balsjö Experimental Area', a paired catchment study which is located approximately 70km from the city of Umeå in northern Sweden. I am responsible for all field activities at this research site. My special interest there is the interaction of hydrological and biochemical processes affecting the dynamic of Dissolved Organic Carbon (DOC) concentrations in streamwater.
