Hefur þú einhvertíman pælt í því hvernig fyllst er með fari laxfiska upp árnar, og af hverju það skiptir máli? Talningar á fiskum hjálpa líffræðingum að meta heilsu fiskistofns, hvort verndunar aðgerðir séu að virka og hvernig vistkerfið er að breytast með tímanum. Hvernig þetta er gert núna, þá þarf fólk að horfa á […]

Have you ever wondered how salmonids migrating up a river get tracked? And why this matters? Fish counts help biologists understand whether fish populations are healthy, whether conservation efforts are working, and how ecosystems change over time. Right now, this often means people are spending hours watching video from underwater cameras. The work is

Hvað eiga flóðhestar og fiskar sameiginlegt? Þeir geta verið mjög litlir! Lífverur geta með tímanum þróast að verða alltaf með smærri og smærri líkama, á ensku kallast þetta fyrirbrigði „miniaturisation“. Það á sér oft stað á eygjum eða á svæðum þar sem stofnar eru aðskildir frá öðrum stofnum. Vísindamenn skilja enn ekki til fulls hvers

What do a hippo and a fish have in common? They come in small sizes! Miniaturisation is when animals evolve to be smaller over time. This often happens on islands or in places where populations are cut off from others. Scientists still don’t fully understand why this happens. Dr. Kalina Kapralova and other researchers
From fishing for Pacific salmon with her dad in the United States to earning her MSc at the University of Iceland, Kenedy Williams has always followed her passion for biology. Her master’s research explored craniofacial adaptations in salmonid fishes, comparing jaws and teeth across populations to understand how diet shapes bone structure. The project combined fieldwork, lab work, and detailed computer-based landmarking. Now a graduate, Kenedy continues working with her lab while assisting in teaching. Her advice to aspiring scientists? Start early, send the email, and never be afraid to try — you never get what you don’t ask for.

Bottom trawling is harmful to life on the ocean floor. Many people agree with this. But we still need to learn more about how and why it causes damage. Mason Kenny wanted to better understand the impact of bottom trawling gear on the seafloor. During his Master’s in Environmental and Natural Resources at The

Botnvörpuveiðar eru skaðlegar fyrir lífið á hafsbotninum. Margir eru sammála þessari staðhæfingu. En það er enn margt ólært um hvernig og hvers vegna þær valda skaða. Mason Kenny vildi skilja betur áhrif botnvörpuveiðarfæra á hafsbotninn. Sem hann kannaði nánar í meistaranáminu sínu í Umhverfis og auðlindafræði við Háskóla Íslands. Mason vann í samstarfi

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
