Marcos Lagunas and his collaborators from the University of Iceland and the Marine and Freshwater Institute teamed up for a project on the genetics of brown trout. Last year, they published an article where they looked into the genetic structure of different trout populations in Thingvallavatn and Ölfusá. The decline of trout in Thingvallavatn […]

But what is biodiversity, and why do we need to protect it? „Biodiversity“, a term that we are confronted with every day, whether we hear about it in the media or read about it in scientific articles. Simply said, biodiversity describes the variety of all living things on Earth, from plants and animals, to fungi
Can we protect biodiversity with fisheries laws? Read More »
Have you ever wondered about all the kinds of fish are out there in the deep oceans? Have you ever heard of the glacier lantern fish? In July, we introduced you to Charlotte Matthews, a marine biologist with a passion for the mesopelagic zone of the ocean. Since then, Charlotte has not only moved

Anja Nickel and her co-authors, Dr. Steven Campana and Dr. Guðbjörg Ásta Ólafsdóttir, published a paper this past summer in Journal of Fish Biology about the movement of juvenile Atlantic cod (Gadus morhua) and saithe (Pollachius virens) in the shallow coastal waters. With the use of acoustic telemetry, Anja and her team, investigated the effect

In the picture above Rakel is drilling a hole in the ice covering lake Garðsvatn in winter time. She collected a water sample and took basic measurements like temperature. Rakel Þorbjörnsdóttir is a curious and bubbly person that I have had the pleasure of working with throughout my PhD. Her curiosity and boundless

Today I get to talk about my own paper! Last year we published an article where we introduced a method we developed to detect and monitor Salmonid spawning grounds using a drone and machine learning. Spawning nests are where the fish release their eggs and the eggs develop until the fish hatch. You

In a recent publication, Theresa Henke and co-authors looked at what anglers think about European flounder (Platichthys flesus). Flounder is an alien species that has been swimming in Icelandic waters since around 1999 and can now be found in fjords, rivers and lakes in most regions of Iceland. In many regions flounder can be

Written with Guðbjörg Ósk Jónsdóttir. At the end of May Guðbjörg Ósk Jónsdóttir and her team published an article on the diversity of jaw bones in Arctic charr. They looked into the differences in the skull of the Arctic charr morphs in Thingvallavatn. A little bit of background on the Arctic charr

In April Sammi Lai and her team published an article about how the amount and variety of food affects young salmon. Their study sites were four rivers in Northeast Iceland (see map). They looked into which invertebrates (animals without a backbone) could be found in the rivers and by finding out what young salmon
