1. Characterization of Mitilysin Pores by Cryo-electron Microscopy
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : Pore forming toxins (PFTs) are a large group of proteins found mainly in bacteria with some exceptions found in animals. They bind and form pores in their target membranes and form pores, which leads to cell death. Among these are cholesterol-dependent cytolysins (CDC), which require the presence of cholesterol to bind target membranes. READ MORE

2. Applying LPJ-GUESS on the Arctic: A model evaluation and benchmarking study
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Warming in the Arctic occurs at a much higher rate than the global average, which has a considerable impact on the Arctic terrestrial carbon cycle. Permafrost thawing can release substantial amounts of carbon, whilst tundra shrubification and tree-line advance, on the other hand, may compensate for this. READ MORE

3. A detailed study on Amazon Forest structure and mortality rates through LPJ-GUESS vegetation model
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Nowadays it has become relevant for scientists to understand the impact of tropical forest structure on the Global Carbon Cycle. Dynamic vegetation models have been developed to pursue this issue, specifically by improving algorithms that could analyze the allometry, biomass content and mortality rate of each singular simulated plant individual and how this responds to climate change, management and rising CO2 concentrations.

4. Modelling vegetation dynamics and carbon fluxes in a high Arctic mire
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : High Arctic wetlands are an important component of the global climate system. Nevertheless estimations of their expected response to climate change and associated climate-feedbacks have large uncertainties. Improving models for vegetation and carbon dynamics of ecosystems is an important step towards making predictions more accurate. READ MORE

5. Impacts of Climate Change on Abies spectabilis : an approach integrating a Species Distribution Model (MaxEnt) and a Dynamic Vegetation Model (LPJ-GUESS)
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Recent global warming trends, particularly in the arctic regions and Himalayas are modifying forest structure and function, notably biogeographical changes in tree species distribution together with alteration in Net Primary Production (NPP), Leaf Area Index (LAI) and Carbon biomass. These alterations are most pronounced in mountain environments, carrying significant impacts on woody species which are more sensitive to temperature changes. READ MORE
