1. Do OTC warming effects on ecosystem processes depend on moss species identity, precipitation, and moss removal?
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Long-term warming experiments in arctic tundra have resulted in reduced moss cover and increased vascular plant cover. As mosses have a major impact on microclimatic conditions, changes in community composition can potentially alter direct and indirect drivers of productivity and decomposition, which are low in arctic ecosystems.

2. Drivers of decomposition across Sphagnum bog margins
Master-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)Sammanfattning : Peatlands provide multiple ecosystem services, including extensive carbon sequestration and storage, yet many peatlands have been degraded or destroyed. Peatlands carbon storage capacity is connected to inherently low decomposition rates, causing the build-up of organic matter. LÄS MER
3. Weight losses of Green tea and Rooibos tea in an aquatic environment : The importance of leaching when estimating decomposition rates
Kandidat-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)Sammanfattning : Leaching is one of the major processes occurring when organic litter is decomposed and is often completed within a few days when litter enters aquatic environments. It is important that leaching is addressed when studying microbial and invertebrate decomposition rates in order to avoid overestimations. LÄS MER
4. Tea time for soils : decomposition experiments in Swedish long-term field trials
Master-uppsats, SLU/Dept. of EcologySammanfattning : Abstract Soils represent a large carbon pool, with almost twice the amount contained in living plant biomass and the atmosphere combined. Consequently, soil has a significant impact on the global C cycle and it is suggested that soil organic C (SOC) sequestration is one of the most cost-effective alternatives to counteract climate change.
