    Human population expansion and associated degradation of the habitat of many wildlife species cause loss of biodiversity and species extinctions. The small Simen Mountains National Park in Ethiopia is one of the last ...
  • Unknown author (Research report / Forskningsrapport, 1955)
    Field note books Notebooks from a sampling project: collecting marine benthic invertebrates in the Oslofjord during the years 1951-1955. The project was organised from the Biological Station in Drøbak, University of ...
  • K, Supriya; Rowe, Melissah; Laskemoen, Terje; Mohan, Dhananjai; Price, Trevor; Lifjeld, Jan Terje (Journal article / Tidsskriftartikkel / SubmittedVersion, 2016)
    Sperm morphological traits are highly variable among species and are commonly thought to evolve by post-copulatory sexual selection. However, little is known about the evolutionary dynamics of sperm morphology, and whether ...
