• Conditions favouring hard seededness as a dispersal and predator escape strategy 

      Paulsen, Torbjørn Rage; Högstedt, Göran; Ken, Thompson; Vandvik, Vigdis; Eliassen, Sigrunn (Peer reviewed; Journal article, 2014-09-16)
      1. The water-impermeable seed coat of ‘hard’ seeds is commonly considered a dormancy trait. Seed smell is, however, strongly correlated with seed water content, and hard seeds are therefore olfactionally cryptic ...
    • The crypsis hypothesis explained: a reply to Jayasuriya et al. (2015) 

      Paulsen, Torbjørn Rage; Colville, Louise; Daws, Matthew I.; Eliassen, Sigrunn; Högstedt, Göran; Kranner, Ilse; Thompson, Ken; Vandvik, Vigdis (Peer reviewed; Journal article, 2015-08-18)
      In imbibing seeds, resumption of metabolism leads to the unavoidable release of volatile by-products that are perceived as cues by rodent seed predators. The crypsis hypothesis proposes that the primary function of a ...
    • Nest distribution and nest habitat of the Tibetan Partridge ( Perdix hodgsoniae ) near Lhasa, Tibet 

      Dorge, Tsering; Högstedt, Göran; Lislevand, Terje (Peer reviewed; Journal article, 2014-10-10)
      Background: Little is hitherto known about the breeding ecology of the Tibetan Partridge (Perdix hodgsoniae) which is endemic to the Tibetan plateau. Here we describe nest densities, inter-nest distances and general nest ...

    • Period lenght in cyclic animal populations 

      Högstedt, Göran; Seldal, Tarald; Breistøl, Arild (Peer reviewed; Journal article, 2005)
      Although cyclic animal dynamics have long been a focus of scientific interest, the variable cycle lengths are poorly understood. Based on a review of the literature, we suggest that period length in animals showing multiannual ...
    • When to reproduce? A new answer to an old question 

      Skorping, Arne; Jensen, Knut Helge; Mennerat, Adele; Högstedt, Göran (Peer reviewed; Journal article, 2016-04)
      We present a life-history model based on the assumptions that juvenile survival follows a negative exponential function and that fecundity gain increases linearly with time to maturity. This model predicts that the optimal ...
