Research theme 6: The behaviour of barnacles (Amphibalanus improvisus) and mussels (Mytilus edulis) to an increased temperature

Global seawater temperatures are predicted to rise due to climate change. We will study the effects of elevated temperature on barnacles and mussels in Tjärnö Bay by the mean of laboratory experiments. To quantify the feeding rates of both species, we will measure their clearance rates using a plankton cell count. In addition, we will visually observe their feeding behaviour in the presence of one another. Lastly, we will place clean substrate of different materials e.g. rock, beverage tin can and mussel in the tanks with barnacles present. In case settlement of barnacle larvae occurs, we will be able to observe substrate preference at ambient and elevated temperatures.

IMBRSea Summer School embarks in Tjärnö

The International Master of Science in Marine Biological Resources (IMBRSea - www.imbrsea.eu ), this year organizes the first summer schools at the Tjärnö Marine Laboratory in Sweden. From 1 till 11 August 39 students and 10 teachers are working on seven challenging research projects. Follow the adventures of the seven research teams in the coming weeks via this blog!

Once upon a time in a land far far north…

Hello fellow marine science lovers! This is the first of a series of blogposts in which we will tell you about our time at Tjarno Marine Station, in Sweden, as part of the Joint School module of IMBRSea master’s programme. Our group is formed of 5 intrepid ocean researchers-to-be from very diverse backgrounds both in terms of our previous studies and country of origin. The aim of the Joint School module is to replicate the process of producing a research paper, therefore we will be planning, designing, executing and hopefully succeeding at producing a great study! This is our crew looking very confused during our first brainstorming meeting!     Getting to know the new lands... Our proposed study is, on broad terms, about the fauna (we chose snails!) we find in the microtidal zone along the West Coast of the Swedish Baltic sea. Microtidal refers to the fact that the tidal movements here are very small, a lot less than what most of us were used to in central w...

The beginning of 10 intense days

It’s August 1, 2018 and there are a lot of enthusiastic students in the normally quiet Tjärnö. The reason for their excitement is the beginning of the Joint School. For ten days they will work together in groups at the Sven Lovén Centre for Marine Infrastructure to conduct a small research project. Of course, they are also very excited to see each other again after one month of separation. As the day passes by, it gets more and more active on the island. And soon the little groups start to chat about a possible research topic. There is a welcome presentation and a nice first dinner, and after, the groups start brainstorming. This blog will follow a particular group of students. Our group consists of six students that want to dedicate these ten days to rocky shores, and more importantly what lives on these shores. That’s why we call ourselves ‘The Rockers’. As it gets darker and some are seeking for b e e r, our plan starts to form. The second day is a whole day dedicated to writing...
