  1. 16. P-cycling in sub-Arctic lakes – the importance of sediment release and retention

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Hanna Ravry; [2022]
    Keywords : phosphorus; sediment; oligotrophication;

    Abstract : Oligotrophication is generally caused by a decreased nutrient availability, usually due to phosphorous limitation. This is a phenomenon impacting the entire food web and at worst causing cascading alterations within an ecosystem. Lakes of the Northern Hemisphere have lately been documented to be subjected to oligotrophication (e.g. READ MORE

  3. 17. Spatial resolution of methane production and ebullition in Lake Alsta

    University essay from Uppsala universitet/Limnologi; Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Evelina Hiltunen; [2021]
    Keywords : methane; ebullition; TN;

    Abstract : Freshwater ecosystems cover about 4 % of the Earth’s surface. Yet they are important components in the global C cycle, as they in addition to their within-lake primary production, receive and process organic matter loads originating from terrestrial environments. The boreal forest biome has the highest density of lakes globally. READ MORE

  4. 18. The kinetic characterization of mutated cyanobacterial dual-functioning fructose/sedoheptulose bisphosphate using a malachite green colorimetric assay

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Albert Jousif Anis; [2021]
    Keywords : Cyanobacteria; carbon fixation; metabolic engineering; protein engineering; colorimetric enzyme assay; rational design; enzyme kinetics; applied microbiology; Biology and Life Sciences;

    Abstract : The increased human dependence on fossil-based fuels, industrial chemicals, and structural materials has caused a drastic increase in atmospheric CO2 levels during the past 50 years. Consequences of this have been observed in the disruption of terrestrial and aquatic ecosystems. READ MORE

  5. 19. Impact of different light sources on the responses of moth

    University essay from Högskolan i Halmstad

    Author : Yanhe Zhou; [2021]
    Keywords : Artificial light at night ALAN ; Greater wax moth; Light Attraction; light emitting diodes; LED; Galleria mellonella;

    Abstract : In recent decades, the negative effects of artificial light at night on natural ecosystems have attracted the attention of ecologists. Studies have shown that artificial light at night leads to a considerable reduction in insects and has a worrying impact on terrestrial ecosystems, including nocturnal insects (e.g. Lepidoptera) such as moths.

  6. 20. A detailed study on Amazon Forest structure and mortality rates through LPJ-GUESS vegetation model

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Sara Mazzuoli; [2021]
    Keywords : Amazon s Forest; LPJ-GUESS; simulation; TEAM-NETWORK; dynamic vegetation model; observation; mortality; allometry; tree stand structure; biomass; cohort; PFTs; plant functional types; NPP; Earth and Environmental Sciences;

    Abstract : 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.
