Effects of weather and hunting on wild reindeer population dynamics in Hardangervidda National Park
Bargmann, Tessa; Wheatcrof, Edward; Imperio, Simona; Vetaas, Ole Reidar (Peer reviewed; Journal article, 2020)Wild reindeer have a range that extends across the circumpolar region. In the last few decades, however, populations of wild reindeer have been on the decline. The reasons for these declines are poorly understood, but are ... -
Life after fire: smoke and ash as germination cues in ericads, herbs and graminoids of northern heathlands
Bargmann, Tessa; Måren, Inger Elisabeth; Vandvik, Vigdis (Peer reviewed; Journal article, 2014-05-02)Question: What is the impact of the fire cues smoke and ash on seed germination of important functional groups in the heathland system, namely ericads, herbs and graminoids? We predict that if germination from heathland ... -
Life after fire: the impact of fire on species composition and diversity in coastal heathlands
Bargmann, Tessa (Doctoral thesis, 2015-09-11)Fire prone coastal heathlands are widespread, and range from naturally fire prone Mediterranean-type heathlands, to the anthropogenic heathlands of north-west Europe. Regardless of its source, fire is an important disturbance ... -
Species trait selection along a prescribed fire chronosequence
Bargmann, Tessa; Heegaard, Einar; Hatteland, Bjørn Arild; Chipperfield, Joseph; Grytnes, John-Arvid (Peer reviewed; Journal article, 2016-09)1. Fire is a widespread management practice used in the maintenance of European heathland. Frequent prescribed burns in small patches have been shown to benefit carabid communities; however, how fire favours specific ... -
Transition from heathland to scrub in south-eastern Tasmania: extent of change since the 1970s, floristic depletion and management implications
Bargmann, Tessa; Kirkpatrick, Jamie B. (Peer reviewed; Journal article, 2015-02)Heathland is a speciose and floriferous vegetation type, defined by its stature (<2 m) and dominance by scleromorphic shrubs. Heathland has been in decline globally, and much of its loss has been due to less frequent fire, ...
