    • Distribution, Population Biology, and Trophic Ecology of the Deepwater Demersal Fish Halosauropsis macrochir (Pisces: Halosauridae) on the Mid-Atlantic Ridge 

      Bergstad, Odd Aksel; Clark, Laura; Hansen, Hege Ø.; Cousins, Nicola (Journal article; Peer reviewed, 2012-02-22)
      Halosauropsis macrochir ranked amongst the most abundant and widespread demersal fishes on the mid-Atlantic Ridge of the North Atlantic (Iceland-Azores) with greatest abundance at 1700–3500 m. All sizes, ranging from 10–76 ...

    • Habitat choice by marine zooplankton in a high-latitude ecosystem 

      Fossheim, Maria; Primicerio, Raul (Journal article; Peer reviewed, 2008-07-29)
      According to habitat choice theory, zooplanktonic prey should choose a depth habitat that maximizes food intake while minimizing predation risk. Body size affects competitive ability and vulnerability in zooplankton, ...
