1. 1. IDENTIFICATION OF ENVIRONMENTALLY RELEVANT BENTHIC FORAMINIFERA FROM THE SKAGERRAK FJORDS BY DEEP LEARNING IMAGE MODELING

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Marko Plavetic; [2023-06-26]
   Keywords : benthic foraminifera; deep learning; environmental monitoring; YOLOv7;

   Abstract : Over the several past decades, there has been increasing interest in using foraminifera as environmental indicators for coastal marine environments. As compared to macrofauna, which are currently used in environmental studies, foraminifera offer several distinct advantages as bioindicators, including short generation times, a high number of individuals per small sample volume, hard and durable tests with high preservation potential, and low cost of sample extraction.

3. 2. Temperature Optimum for Biomass Production of two Species of Benthic Diatoms

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Vilmer Jansson; [2023-06-22]
   Keywords : ;

   Abstract : Diatoms and other algae can be cultivated and beneficially used in several sectors with applications ranging from nutrient recycling to production of high-valued biomaterials used by the green energy industries, in pharmaceutical products or as food supplements. In this experimental study, the temperature optimum for biomass production was tested for two species of benthic diatoms, Diatoma sp. READ MORE

4. 3. INFLUENCE OF TEMPERATURE ON BIOMASS AND GROWTH RATE OF BENTHIC DIATOMS

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Evelina Hansson; [2023-06-21]
   Keywords : benthic; diatoms; cultivation; thermal performance; photosynthetic pigments;

   Abstract : Temperature has a significant impact on structure and abundance of microalgal community as well as on physiology (Sheehan et al., 2020). READ MORE

5. 4. Response of foraminifera Ammonia confertitesta (T6) to ocean acidification, warming, and deoxygenation - An experimental approach

   University essay from Lunds universitet/Geologiska institutionen

   Author : Elsa Muller; [2023]
   Keywords : Acidification; Warming; Deoxygenation; Foraminifera; Ammonia confertitesta T6 ; Culture Experiment; Trace elements; Earth and Environmental Sciences;

   Abstract : Ocean acidification, warmer temperatures, and the expansion of hypoxic zones in coastal areas are direct consequences of the increase in anthropogenic activities. However, so far, the combined effects of these stressors on calcium carbonate-secreting marine microorganisms - foraminifera are complex and poorly understood. READ MORE

6. 5. Evaluation of restoration efforts in Dalälven - conditions for survival rate of Salmo trutta and Salmo salar

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Ville Svärd; [2023]
   Keywords : Restoration; river; salmonids; benthic fauna;

   Abstract : Rivers are among the most anthropogenically affected ecosystems in the world by irrigation, transportation, channelizing, and hydropower. Habitat restorations have become a popular method to restore the heterogeneity and complexity of rivers aiming for improvement of biodiversity. READ MORE
