11. The Effect of Snow on Plants and Their Interactions with Herbivores
Sammanfattning : The ongoing climate changes are predicted to accelerate fast in arctic regions with increases in both temperatures and precipitation. Although the duration of snow cover is generally expected to decrease in the future, snow depth may paradoxically increase in those areas where a large amount of the elevated precipitation will fall as snow.

12. Phytoplankton and Physical Disturbance : Seasonal dynamics in temperate Lake Erken, Sweden
Sammanfattning : Phytoplankton mirrors changes in the environment and plays an important role in biogeochemical processes. Phytoplankton dynamics is the outcome of both autogenic succession and external disturbances. LÄS MER
13. On the intra-seasonal to decadal climate variability over South-Asia
Sammanfattning : South Asia, a land of contrasting landscapes, seasons and climates, is highly vulnerable to climate variability over intra-seasonal to decadal time scales. In winter, precipitation over the western parts of south Asia and fog over the Indo-Gangetic (IG) plains are the two major climatic features. LÄS MER
14. Nutrient limitation and elemental ratios in Baltic Sea plankton
Sammanfattning : Phytoplankton growth is frequently limited by the supply of nitrogen (N), phosphorus (P), or sometimes other elements. N2-fixing cyanobacteria are favoured by N limitation, which they may alleviate by adding new N to the ecosystem. LÄS MER
15. Palsa Growth and Decay in Northern Sweden : Climatic and Environmental Controls
Sammanfattning : This thesis outlines the development and decay of palsas in northern Sweden in relation to climatic and environmental factors. Palsas were investigated on morphology, vegetation, peat porosity, ground temperature and local climate in four bogs situated on a north-south gradient in northern Sweden. LÄS MER
