Lögunar og erfðafræðilegur breytileiki milli bleikjuafbrigða í tengdum stöðuvötnum

Leave a Comment / Greinasafn / /

Fyrr á þessu ári var grein birt í tímaritinu Molecular Ecology (eða Sameindavistfræði). Þessi grein var skrifuð af Han Xiao og meðhöfundundum hans, þeim Arnari Pálssyni, Zophoníasi O. Jónssyni og Sigurði S. Snorrasyni. Fjallar hún um lögunar og erfðafræðilegan mun á milli bleikjuafbrigða sem lifa í tveimur nágranna stöðuvötnum hérlendis. Rannsakendurnir söfnuðu ólíkum bleikjuafbrigðum frá […]

Genetic and Shape Differences of Arctic Charr Morphs in Connected Lakes

Leave a Comment / Publication feature / /

Earlier this year Han Xiao along with co-authors Arnar Pálsson, Zophonías O. Jónsson and Sigurður S. Snorrason published a paper in the journal Molecular Ecology. In this paper they explored genetic and shape differences between Arctic charr morphs in two neighbouring lakes in Iceland. They collected different Arctic charr morphs from lake Þingvallavatn and lake

Er ég skrifa þennan pistil er ég stödd í Kanada, hér er ég búin að vera í næstum fimm og hálfa viku. Ég er búin að vera að heimsækja rannsóknarstofu Benedikt Hallgrímssonar (https://hallgrimssonlab.ca/) við Háskólann í Calgary (University of Calgary) í Alberta fylki í Kanada. Þau á rannsóknarstofunni sérhæfa sig í erfða- og formfræðilegum rannsóknum

Let’s micro-CT scan some fish heads

Leave a Comment / Discovery zone / /

As I’m writing this, it is the last week of my five and a half weeks stay at the Benedikt Hallgrímson lab (https://hallgrimssonlab.ca/) at the University of Calgary in Alberta Canada. They specialize in genetic morphometric analysis exploring complex traits in zebrafish, mice, and humans. However, I’m here to micro-CT scan some Arctic charrs. Maybe

Where are the baby Brown trout and Arctic charr?

Leave a Comment / Publication feature / /

  Nursery grounds are habitats mainly used by juvenile (baby) fish. As the name suggests these habitats are like nurseries for fish. Nursery grounds are very important for the fish species using them. Since they provide protection and food for the young. Therefore, knowing where they are and how they are holding up is important.

Halló, ég heiti Guðbjörg og er nýr meðlimur Ice Fish Research. Ég er fædd og uppalin hér á Íslandi. Einmitt núna er ég að stunda doktorsnám í Líffræði við Háskóla Íslands þar sem ég er að rannsaka fjölbreytileika í bleikjum.   Bíddu það elska ekki allir náttúrufræði? Ég ætlaði mér nú aldrei að vera líffræðingur.

Hello, my name is Guðbjörg and I’m a new member of Ice Fish Research. I was born and raised in Iceland. Currently I’m working on my PhD in Biology at the University of Iceland where I research diversity in Arctic charr.   Wait, doesn’t everyone love natural science? I was never going to be a
