1. 1. Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Duncan Jones; [2023]
   Keywords : Geography; Geographical Information Systems; GIS; Habitat Modelling; Harbour Porpoise; MaxEnt; Tidal Processes; Conservation; Earth and Environmental Sciences;

   Abstract : Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall Abstract Unintentional by-catch in fishing gear is a significant cause of mortality of harbour porpoises in UK waters. Understanding the spatial distribution of harbour porpoises at fine scales and how this changes over time is essential when trying to understand where these lethal interactions might occur.

3. 2. Influence of surface water availability on the distribution of White Rhinoceros in central Greater Kruger

   University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

   Author : Julie Mauguiere; [2022]
   Keywords : White Rhinoceros; Ceratotherium simum; water provisioning; artificial water; ecological processes; habitat selection; spatial ecology; landscape use; KNP; APNR; SAWC;

   Abstract : The population of white rhinoceros (Ceratotherium simum simum) is now declining in the Kruger National Park (KNP) in South Africa due to the intense poaching crisis ongoing since the early 2000s. The need for an efficient conservation effort has never been greater and requires a better understanding of white rhinoceros distribution in the landscape. READ MORE

4. 3. Assessment of the Agroecological Potential of Biostimulatory Effects : originating from Effective Microorganisms (EM) in terms of Environmental and Socioeconomic Aspects

   University essay from SLU/Dept. of Biosystems and Technology (from 130101)

   Author : Tania Schwarzer; [2022]
   Keywords : effective microorganisms; agroecology; biostimulants; beneficial microorganisms; lactic acid bacteria; bokashi; semi-structured interviews; interpretative phenomenological approach;

   Abstract : Environmental pollution, resource depletion and climate change are related to imbalances in the farming system. Effective microorganisms are seen as a possible solution to these problems. READ MORE

5. 4. Long-term phosphorus trends in Swedish rivers and streams : widespread and persistent nutrient decline

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

   Author : Sara Camiolo; [2021]
   Keywords : eutrophication; rivers; streams; phosphorus;

   Abstract : Phosphorus (P) is often considered the limiting nutrient for freshwater productivity because of its relevant role in regulating algal production and determining community composition. The concern for increasing anthropogenic P inputs registered since the last century has shaped environmental policies around the world to limit the effects of algal bloom (also known as eutrophication) in freshwater ecosystems through the establishment of maximum threshold nutrient concentrations.

6. 5. Anaerobic degradation of volatile fatty acids in continuous biogas reactors at very short hydraulic retention times.

   University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

   Author : Anna Lea Auguste Weimer; [2019]
   Keywords : Anaerobic digestion; hydraulic retention time; organic loading rate; biogas; applied microbiology; teknisk mikrobiologi; Technology and Engineering;

   Abstract : There is an increasing demand for safe, affordable and above allsustainable energy, due to the exhaustion of fossil fuels and increasing greenhousegas emissions. In this context, anaerobic digestion is of growing interest, as it enablesthe production of the versatile renewable energy source biogas from various types oforganic wastes. READ MORE
