11. 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

12. Effects of restoration on instream bryophyte communities : Monitoring of two different restoration techniques in the Vindel River system
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Ecological restoration is the practice of assisting the recovery of a degraded, damaged or destroyed ecosystem. The aim of this study was to analyse the effects of two different restoration techniques on instream bryophyte abundance, species richness and diversity as well as community composition, in streams channelized for timber-floating.

13. Climate change effects on freezing damage in three subarctic bryophytes : A snow manipulation field experiment in a tundra ecosystem in Abisko, Sweden
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Climate change is expected to have a large impact on northern ecosystems. Increased temperatures and altered precipitation and snow cover patterns will have a great impact on subarctic tundra. Bryophytes form an important component of tundra ecosystems because of their high abundance and their importance in many ecological processes. READ MORE

14. Phippsia concinna in Sweden : Exploring ecological dependencies in a regionally endangered plant species that occurs in alpine snowbeds
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : The purpose of this study is to 1: Get an updated population estimate for the regionally endangered alpine specialist plant Phippsia concinna in Sweden and 2: Explore the ecological dependencies that limits the distributions of this species to late melt-out alpine snowbeds on calcareous soils, and 3: Explore if climate change in the southern part of the Scandes mountain range is causing a decline in the population numbers of P. concinna.

15. Restoration of a Rich Fen by Top Soil Removal : Temporal and Spatial Responses among Vascular Plants, Bryophytes and Land Snails during 15 years
University essay from Institutionen för biologisk grundutbildningAbstract : Rich fens are calcareous and nutrient poor wetlands with a rich flora of orchids, sedges and mosses. As many as one hundred plant species are rich fen specialists. Many wetlands have been drained historically, and transformed to agricultural land or production forests. Today rich fens cover only 2-3% of the total mire area in Sweden. READ MORE
