Effect of altitude on woody vegetation along slopes of a volcanic, tropical mountain
(Master thesis, 2017)This study was initiated to investigate the effects of altitude on woody vegetation on the eastern slopes of Mount Meru, Tanzania. Changes in vegetation along altitudinal gradients are related to climate factors, soil ... -
The effect of aqueous aluminium on mortality and respiration in the amphipod Gammarus lacustris
(Master thesis, 2021)The literature covering freshwater acidification and Al-toxicity in aquatic organisms has mainly focused on fish species sensitivity to acidic Al-rich water. A thorough review of the literature shows that knowledge is far ... -
The effect of aqueous aluminium on mortality and respiration of the isopoda Asellus aquaticus
(Master thesis, 2022)The present study investigates the effect of aqueous aluminium (Al) and acidic water on mortality and respiration in the isopoda Asellus aquaticus. I conducted one mortality experiment lasting 22 days exposing A. aquaticus ... -
The effect of rut and hunting activity on movement in female moose with and without calves
(Master thesis, 2009)Moose (Alces alces) in Norway are exposed to intensive hunting pressure each autumn. Besides the rut, already an energetically costly period of the year, we may expect disturbance to moose by hunters to trigger anti-predator ... -
The effects of artificial water holes on the distribution of elephants and other mammalian herbivores in Savuti, Northern Botswana
(Master thesis, 2010)It has been argued that the wide-scale provision of artificial surface water in semi-arid savannas may result in homogenisation of foraging habitats, compromising biodiversity and ecosystem resilience. This study looks ... -
Effects of different scarification intensities on bilberry abundance
(Master thesis, 2014-09-29)In the boreal forest bilberry (Vaccinium myrtillus) plays an important role for a large variety of insects, birds and mammals, and it is especially important for moose (Alces alces) in autumn and spring. Bilberry is commonly ... -
Effects of GPS-collars on Svalbard reindeer survival and body condition
(Master thesis, 2020)Modern wildlife and conservation research often relies on GPS collars and on the assumption that collared animals are representative of the study population, but this assumption is rarely tested in the wild. These collars ... -
Effects of increased intensity of soil scarification on natural regeneration of Scots pine Pinus sylvestris and birch Betula spp.
(Master thesis, 2016)In this study I tested the effect of high intensity of soil scarification on density and growth of young pine and birch seedlings in natural pine regenerations in Hedmark County, South-eastern Norway. The reason for testing ... -
Effects of moose density and supplementary feeding on field layer vegetation
(Master thesis, 2011)English: Large mammalian herbivores have the potential to directly and indirectly affect the ecosystem they live in, such as plant structure and dynamics of vascular plants. The present study experimentally estimated the ... -
Effects of reduced liming on brown trout (Salmo trutta L.) in four small tributaries in eastern Norway.
(Master thesis, 2020)Acidification of surface waters due to acidic precipitation has led to a reduction in biological diversity. Through international conventions, emissions causing the acidic precipitation has decreased. The hallenges associated ... -
Eradicating the American bullfrog with the sterile triploid method: methods and application
(Master thesis, 2021)The American bullfrog, an invasive species present all around the world, causes many problems in ecosystems. They are very hard to eradicate because of their complex developmental stages, their abundance, high fertility, ... -
Estimating ungulate carrion biomass and possible ecological effects on red fox (Vulpes vulpes) in central Norway
(Master thesis, 2014)Ungulates constitute the bulk of carrion in many terrestrial ecosystems. Knowledge of carrion availability is paramount to understand its ecological effects and I aimed to estimate carrion availability in Nord-Trøndelag ... -
Eurasian lynx ( Lynx lynx ) and wolverine ( Gulo gulo ) response to seasonal variation in prey availability: influences on space use, seasonal site fidelity and reproduction
(Master thesis, 2015)In systems with migratory prey, resource availability varies seasonally and can modify the spatialorganization of carnivores. Pred ators within these systems must therefore adopt a strategy to deal with prey movements when ... -
Evaluating potential drivers of four different types of moose browsing damage in a cross-border context
(Master thesis, 2022)Moose (Alces alces) in Scandinavia rely on commercially valuable Scots pine (Pinus sylvestris) as a winter food source. Browsing impacts to forest resources are labeled as “damage” and have become especially important along ... -
Fantastic beavers (Castor fiber) and where to find them: Using availability of suitable habitat to estimate beaver populations sizes
(Master thesis, 2022)The Eurasian beaver was significantly over harvested for its pelt and for what is called castoreum, and the global population was estimated to be 1200 individuals. Today, the Eurasian beaver population is estimated to be ... -
Food preferences by spring migrating Pink-footed geese (Anser brachyryhnchus) in Central Norway
(Master thesis, 2013)The spring migrating Svalbard population of Pink - footed geese (Anser brachyrhynchus) stages in Central - Norway from mid - April to mid - May. They feed on agriculture fields mainly on a menu of grain and ... -
Foraging by elephant, giraffe and impala during wet and dry season in rich and poor savanna, Tanzania
(Master thesis, 2015)Plant have evolved traits in response to herbivory and these traits depends on soil nutrient status, plants in nutrient rich soils have evolved tolerance to herbivory by being palatable and those in nutrient poor have ... -
Gastrointestinal parasites in moose (Alces alces); which ones and what consequences?
(Master thesis, 2014-09-29)Even though the moose in Norway represents such an important game species, this is one of the first studies of their gastrointestinal parasites. The moose population density in Hedmark county remains at a high level, and ... -
Gastrointestinal parasites in sympatric reindeer (Rangifer tarandus) and sheep (Ovis aries) - Evidence of spillover and consequences thereof
(Master thesis, 2020)Understanding the role of gastrointestinal parasites for ecosystems and their potential impact on their hosts is valuable knowledge within wildlife management. In Norway, there is a long tradition mountain grazing for ... -
Gone to the dogs : Comparison of approaches to livestock protection against large carnivores in Slovakia and Norway
(Master thesis, 2015)The use of livestock guardian dogs (LGDs) to prevent depredation is considered to be a powerful conservation strategy for the mitigation of conflicts between farmers and wildlife, and is currently on the rise worldwide. ...
