    • Energetics of whiskered bats in comparison to other bats of the family Vespertilionidae 

      Skåra, Karoline Hansen; Bech, Claus; Fjelldal, Mari Aas; van der Kooij, Jeroen; Sørås, Rune; Stawski, Clare (Peer reviewed; Journal article, 2021)
      Bats inhabit a variety of climate types, ranging from tropical to temperate zones, and environmental differences may therefore affect the basal metabolic rate (BMR) of bats from different populations. In the present study, ...

    • Family planning in the high Arctic: earlier spring onset advances age at first successful reproduction in barnacle geese 

      Fjelldal, Mari Aas (Master thesis, 2018)
      I en verden under oppvarming der arter møter nye miljøforandringer er evalueringen av klimaeffekter på individnivå gjennom livshistorie egenskaper viktig for å forstå langtids- utsiktene til naturlige populasjoner. ...

    • Physiological and ecological challenges faced by small bats in summer 

      Fjelldal, Mari Aas (Doctoral theses at NTNU;2023:89, Doctoral thesis, 2023)
      Summary of thesis: A majority of bat species are small, insectivorous and strictly nocturnal. With temporally restricted foraging opportunities, a food source that varies with weather fluctuations, and high energetic ...

    • State dependence of arousal from torpor in brown long-eared bats (Plecotus auritus) 

      Sørås, Rune; Fjelldal, Mari Aas; Bech, Claus; van der Kooij, Jeroen; Skåra, Karoline Hansen; Eldegard, Katrine; Stawski, Clare (Peer reviewed; Journal article, 2022)
      To cope with periods of low food availability and unsuitable environmental conditions (e.g., short photoperiod or challenging weather), many heterothermic mammals can readily go into torpor to save energy. However, torpor ...

    • Torpor arousal rates in northern bats (Eptesicus nilssonii) 

      Skauge, Silje Huse (Master thesis, 2022)
      Endoterme dyr holder ofte kroppstemperaturen sin høy og stabil i møte med mange miljøbetingelser, noe som krever mye energi. For å unngå energiutfordringene bruker mange pattedyr torpor, en prosess hvor kroppstemperatur, ...

    • Universality of Torpor Expression in Bats 

      Fjelldal, Mari Aas; Sørås, Rune; Stawski, Clare (Peer reviewed; Journal article, 2022)
      Although heterothermy is employed by species at a global level within the order of Chiroptera (bats), the possibility of torpor being expressed in bat species inhabiting warmer climate zones has been explored only in the ...
