    • Aspects of spermatogenesis in immature and mature specimens of the long-lived Greenland shark: novelties concerning the germinal compartment’s assembly, complement of Sertoli cells and demise 

      McClusky, Leon Mendel; Nielsen, Julius; Christiansen, Jørgen Schou (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-06-07)
      Cystic spermatogenesis in the subadult, maturing and adult Greenland shark (Somniosus microcephalus) displays multiple novel features, characterized early on by an unorganized internal cellular environment of the spermatocysts (anatomically discrete follicle-like units containing a single germ cell stage and its complement of co-developing Sertoli cells). These typically show polar asymmetries due ...
    • Rapid Ice‐Wedge Collapse and Permafrost Carbon Loss Triggered by Increased Snow Depth and Surface Runoff 

      Parmentier, Frans-Jan W.; Nilsen, Lennart; Tømmervik, Hans; Meisel, Ove H.; Bröder, Lisa; Vonk, Jorien E.; Westermann, Sebastian; Semenchuk, Phillip R.; Cooper, Elisabeth J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-06-16)
      Thicker snow cover in permafrost areas causes deeper active layers and thaw subsidence, which alter local hydrology and may amplify the loss of soil carbon. However, the potential for changes in snow cover and surface runoff to mobilize permafrost carbon remains poorly quantified. In this study, we show that a snow fence experiment on High‐Arctic Svalbard inadvertently led to surface subsidence ...
