Research theme 4: Effect of temperature on the feeding behaviour of shrimp (Palaemon sp.) in the presence of a predator and a competitor.

Animal behavior can vary depending on many factors. Temperature, competition, and predation risk are only a few of the drivers that can influence the behavior of animals. The aim of this project is to assess the feeding behaviors of Palaemon sp. in response to competition, predation risk, and a projected increase in water temperature. Therefore, specimen collected in the coastal waters of Tjärnö will be transplanted into experimental tanks where they will be exposed to eight different treatments of varying behavioral drivers. Temperature rise will be simulated by increasing the temperature of the water in half of the tanks to 30°C. Competition will be simulated by exposing half of the shrimp to a competitor of the same species. Finally, a specimen of Carcinus maenas serves as a predator. Eight replications of each treatment will be conducted and feeding behavior and intra- and interspecific interaction will be recorded.

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...
