11. Nitrogen fixation by cyanobacteria associated to feathermosses : a comparison between Scots pine and Norway spruce stands
University essay from SLU/Dept. of Forest Ecology and ManagementAbstract : The limitations of available nutrients are strong in the boreal forest, especially of nitrogen (N). Due to slow mineralization rate of organic soil nitrogen, caused by low temperatures and acidic soils. Few organisms can fixate atmospheric nitrogen. Among those who have the ability there are some that are common in the boreal forest. READ MORE

12. Effects of altered precipitation regimes on bryophyte carbon dynamics in a Peruvian tropical montane cloud forest
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Tropical montane cloud forests (TMCF) are unique ecosystems that are frequently surrounded by clouds which increase humidity and promote the growth of bryophytes. Several dimensions of humidity are important for the carbon dynamics of bryophytes. Climate change is therefore projected to have a large impact on them as well as on the TMCF itself. READ MORE

15. Nitrogen fixation among boreal feather mosses along a clear-cut chronosequence
University essay from SLU/Dept. of Forest Ecology and ManagementAbstract : The Swedish boreal forests are limited by nitrogen (N) availability. While biological N2 fixation by cyanobacteria hosted by pleurocarpous feather mosses are important sources of N input to natural boreal forest ecosystems, little is known about the patterns of N2 fixation in silvicultural systems.
