3. 2. Mercury accumulation in lake sediments on different time scales – the influence of algal primary production

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Anne Rebotzke; [2023]
   Keywords : mercury; lake sediment; primary productivity; algal scavenging; biogenic silica; diatom proxy; chlorophyll-a; organic matter;

   Abstract : The aim of this work is to test the proposed approach of algal scavenging as a driver of sediment mercury (Hg) on different time scales and to gain a better understanding of the mechanisms of Hg accumulation in lake sediments. A 3000-year sediment record from Nylandssjön in northern Sweden was analysed for this purpose, as well as a 20-year sediment record from the seasonal sediment traps of this lake. READ MORE

4. 3. Can cellular osmolarity be used as a predictor for drought tolerance in common bean?

   University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

   Author : Ella Köster; [2022-08-16]
   Keywords : ;

   Abstract : Common bean, Phaseolus vulgaris, is a protein and nutrient rich food source grown around the world. Rwanda has one of the highest per capita consumption rates in the world. With climate change threatening food security, the need for more adaptable crops is rising. READ MORE

5. 4. CAN LEAF LEVEL GAS EXCHANGE BE USED AS A PREDICTOR FOR DROUGHT TOLERANCE IN COMMON BEAN (PHASEOLUS VULGARIS)?

   University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

   Author : Villemo Holmberg; [2022-08-16]
   Keywords : ;

   Abstract : This study aimed to examine drought tolerance among a variety of landraces of the species Phaseolus vulgaris to discover whether leaf level gas exchange can be used as a predictor for drought tolerance. Beans of different landraces from Rwanda were planted and when they had grown for four weeks a leaf-level gas exchange analysis was carried out, measuring one leaf from each plant both during the day and night.

6. 5. Design and implementation of embedded system for chl-a fluorescence detection

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Anargyros Katsogridakis; [2021]
   Keywords : Embedded systems; Microcontrollers; Harmful algal bloom; Climate change; chl-a fluorescence; Inbyggda system; mikrokontroller; skadlig algblomning; klimatförändring; chl-a-fluorescens;

   Abstract : Over the last decades, the effects of climate change have become increasingly evident across natural environments. Apart from other areas, climate change poses a serious threat on water quality. READ MORE
