Effects of nutrient addition on vegetation and carbon cycling in an ombrotrophic bog

We measured net ecosystem CO2 exchange (NEE), plant biomass and growth, species composition, peat microclimate, and litter decomposition in a fertilization experiment at Mer Bleue Bog, Ottawa, Ontario. The bog is located in the zone with the highest atmospheric nitrogen deposition for Canada, estimated at 0.8–1.2 g N m 2 yr 1 (wet deposition as NH4 and NO3). To establish the effect of nutrient ...

Vegetation feedbacks of nutrient addition lead to a weaker carbon sink in an ombrotrophic bog.

To study vegetation feedbacks of nutrient addition on carbon sequestration capacity, we investigated vegetation and ecosystem CO2 exchange at Mer Bleue Bog, Canada in plots that had been fertilized with nitrogen (N) or with N plus phosphorus (P) and potassium (K) for 7-12 years. Gross photosynthesis, ecosystem respiration, and net CO2 exchange were measured weekly during May-September 2011 usin...

Abiotic Stresses to Vegetation Re-establishment in a Cutover Bog Contaminated with Seawater

I hereby declare that I am the sole author of this thesis. This is the true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. Abstract Part of a cutover bog in Pokesudie Island, New Brunswick, Canada was contaminated with seawater and was still largely devoid of vegetation 5 ye...

Deciding ike Humans Do

With the objective of building robots that accompany humans in daily life, it might be favourable that such robots act humanlike so that humans are able to predict their behaviour without effort. Decision making is one crucial aspect of daily life. As Damasio demonstrated, human decisions are often based on emotions. Earlier work thus developed a decision making framework for artificial intelli...
