    • Meiofauna as a valuable bioindicator of climate change in the polar regions 

      Leasi, Francesca; Sevigny, Joseph L.; Hassett, Brandon (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-14)
      Establishing robust estimates of polar marine biodiversity is important for interpreting future changes in the Arctic; however, despite a recent increase in scientific expeditions, this region remains relatively underexplored. Particularly overlooked in biodiversity assessments are small species, such as protists, fungi, and many small invertebrates that are collectively known as meiofauna. These ...
    • New species of aquatic chytrids from Oman 

      Hassett, Brandon; Al-Shaibi, Badriya K.; Al-Nabhani, Abdulrahman; Al-Sadi, Abdullah M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-12)
      Oman is a desert country in the south of the Middle East. Springs and other water sources that harbor aquatic organisms can be separated by hundreds of kilometers. In Oct 2019, we isolated four freshwater aquatic fungi (Chytridiomycota) from benthic detritus baited with pine pollen on a general nutrient medium near Salalah, Oman. Database queries of nuc 28S rRNA (28S) and internal transcribed spacer ...
    • The occurrence of Nematoda in coastal sea ice on Svalbard (European Arctic) determined with the 18S small subunit rRNA gene 

      Pitusi, Vanessa; Søreide, Janne; Hassett, Brandon; Marquardt, Miriam; Andreasen, Magnus Heide (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-06)
      Understanding the diversity and functioning of Arctic sea ice ecosystems is vital to evaluate and predict the impact of current and future climate change. In the microscopic communities inhabiting the brine channels inside sea ice, nematodes often dominate numerically and act as bacterivores and herbivores. Despite nematodes great abundances and known ecological roles, molecular tools have not been ...
    • A Widely Distributed Thraustochytrid Parasite of Diatoms Isolated from the Arctic Represents a gen. and sp. nov. 

      Hassett, Brandon (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-06)
      A unicellular, heterotrophic, eukaryotic parasite was isolated from nearshore Arctic marine sediment in association with the diatom <i>Pleurosigma</i> sp. The parasite possessed ectoplasmic threads that could penetrate diatom frustules. Healthy and reproducing <i>Pleurosigma</i> cultures would begin to collapse within a week following the introduction of this parasite. The parasite (2–10 μm diameter) ...
