Journal article (peer-reviewed)abstract
- Human land use such as pastoralism may be a key determinant of wildlife populations. We studied the influence of land use on wildlife and livestock in south-western Kalahari, Botswana, during the wet and dry seasons. We included two types of livestock areas and two types of wildlife protection areas. Wild and domestic mammals >0.2 kg were sampled by distance technique. Small mammals <0.2 kg were trapped and a vegetation survey was performed. Livestock and some medium-sized wildlife species were most abundant in livestock areas, while large-sized wildlife species were mainly restricted to wildlife areas. Most red-listed species were confined to the national park. The influence of land use on abundances changed moderately between seasons. However, cattle moved into wildlife areas during the wet season. Differences in species richness and diversity were most pronounced during the dry season. The trapping frequency of small mammals was highest in the national park. Differences in vegetation structure included sparser field layer and higher cover of an invasive shrub in livestock areas. Our study shows the importance of protected areas for many wildlife species in the Kalahari. It also shows the value of a multi-species approach for investigating the effects of land use on wildlife communities.

Mammal community structure in relation to disturbance and resource gradients in southern Africa
- 2009
-
In: African Journal of Ecology. - : Wiley. - 0141-6707 .- 1365-2028. ; 47:1, s. 20-31
-
Journal article (peer-reviewed)abstract
- The arrangements of mammals differ along environmental gradients, such as of disturbance and resources. We examined how mammal community composition in the Kalahari, Botswana, varied in relation to disturbance and resource gradients. We predicted that livestock-keeping villages are disturbances and pans are resources for wildlife, that the responses of mammals to disturbance and resources depend on their functional types and that increased disturbance over time has reduced the numbers and distributions of wildlife. The methods involved road-side counts of mammals > 0.2 kg and trapping of small mammals, < 0.2 kg. The disturbance gradient was more important than the resource gradient for explaining the distribution of mammals > 0.2 kg. Communities in low disturbance-high resource areas were most diverse regarding species and functional types. Small mammal species richness and abundances were unaffected by villages, but increased with distance from pans. Villages were particularly deterring to large wild herbivores, functionally similar to livestock. Most large wild herbivores had decreased since 1975-1983. We conclude that large and medium-sized mammals are highly affected by large-scale disturbance gradients, while small mammals are most dependent on small-scale variation in resources, probably shelter and food. Increased disturbance over time leads to decreasing ranges and numbers of the large wild herbivores.

Forage availability and moose winter browsing in forest landscapes
- 2018
-
In: Forest Ecology and Management. - : Elsevier BV. - 0378-1127 .- 1872-7042. ; 419-420, s. 170-178
-
Journal article (peer-reviewed)abstract
- In a large-scale survey, comprising 38 landscapes throughout Sweden, we measured winter forage availability and use by moose within different forest- and land types, and also at three different spatial scales: plot, tract and area.Measured as percent cover of browse species within moose browsing range, young forests contained significantly more browse (16.5 +/- 1.20%: mean +/- SE) compared with older forests (6.7 +/- 0.57%) or non-forest land (5.9 +/- 0.67%). Total cover of browse species increased with increasing mean tree height in forests, and peaked at around 22% when the trees were 3-5 m. The relative consumption was highest in young forests (9.2 +/- 0.98%) compared with non-forest land (7.8 +/- 1.40%) or older forests (5.8 +/- 0.78%). The selection order did not vary much among forest- or land types, with aspen, willows, rowan and oak being the most selected species.A multiple regression, including four independent variables (moose index, cover of Scots pine, cover of other species and temperature sum) explained 45% (young forests), 18% (older forests) and 36% (non-forest land) of the variation in relative consumption. In young forests, moose index and cover of Scots pine accounted for 40 and 44%, respectively, of the explained variation. Model selection, using AICc, further emphasized the importance of moose index and cover of Scots pine, as these variables were included in the most parsimonious models for all forest- and land types.At the tract level, we recorded a proportional relationship between total cover of browse species and absolute consumption, suggesting an ideal free distribution. Taking into account the availability of forage, the degree of browsing and the proportion of each land type in the landscape, we calculated that 44.3% of the total forage consumption occurred in young forests, 42.3% in older forests and 13.4% in non-forest land.Our main conclusions are that moose conform to an ideal free distribution based on availability of forage within the landscape, and that all forest- and land types, not just young forests, are important as sources of browse for moose. Thus, it may be possible to release the browsing pressure on damage-sensitive young forests by increasing the food supply in other forest- and land types. Furthermore, managers needs to consider both the size of the moose population and the amounts of browse in the landscape when deciding on prudent management actions.

Blood-brain barrier penetration of zolmitriptan--modelling of positron emission tomography data
- 2006
-
In: Journal of Pharmacokinetics and Pharmacodynamics. - : Springer Science and Business Media LLC. - 1567-567X .- 1573-8744. ; 33:1, s. 75-91
-
Journal article (peer-reviewed)abstract
- Positron emission tomography (PET) with the drug radiolabelled allows a direct measurement of brain or other organ kinetics, information which can be essential in drug development. Usually, however, a PET-tracer is administered intravenously (i.v.), whereas the therapeutic drug is mostly given orally or by a different route to the PET-tracer. In such cases, a recalculation is needed to make the PET data representative for the alternative administration route. To investigate the blood-brain barrier penetration of a drug (zolmitriptan) using dynamic PET and by PK modelling quantify the brain concentration of the drug after the nasal administration of a therapeutic dose. [11C]Zolmitriptan at tracer dose was administered as a short i.v. infusion and the brain tissue and venous blood kinetics of [11C]zolmitriptan was measured by PET in 7 healthy volunteers. One PET study was performed before and one 30 min after the administration of 5 mg zolmitriptan as nasal spray. At each of the instances, the brain radioactivity concentration after subtraction of the vascular component was determined up to 90 min after administration and compared to venous plasma radioactivity concentration after correction for radiolabelled metabolites. Convolution methods were used to describe the relationship between arterial and venous tracer concentrations, respectively between brain and arterial tracer concentration. Finally, the impulse response functions derived from the PET studies were applied on plasma PK data to estimate the brain zolmitriptan concentration after a nasal administration of a therapeutic dose. The studies shows that the PET data on brain kinetics could well be described as the convolution of venous tracer kinetics with an impulse response including terms for arterial-to-venous plasma and arterial-to-brain impulse responses. Application of the PET derived impulse responses on the plasma PK from nasal administration demonstrated that brain PK of zolmitriptan increased with time, achieving about 0.5 mg/ml at 30 min and close to a maximum of 1.5 mg/ml after 2 hr. A significant brain concentration was observed already after 5 min. The data support the notation of a rapid brain availability of zolmitriptan after nasal administration.

A twin-wire model gap former : design and evaluation methods

Journal article (peer-reviewed)abstract
- A one-sided model twin wire gap former, the KTH-former has been developed. The former consists of headbox with transparent gables, forming unit, including a forming roll with a transparent surface and outer forming wire and a reservoir system for water/fibre suspension handling. To allow the study of blade forming, a blade can be introduced against the outer wire to generate a pressure pulse. Two measurement techniques have been utilized to study the flow mechanisms of fibre suspension flow in the forming zone; A pressure sensor has been used to study the dewatering pressure along the forming zone. A high speed video system was used to visually study the suspension flow. The study was made with pulp fibres. Fibre floes were introduced in the center of the headbox at the beginning of the linear nozzle contraction, by an introduction tube with an inner diameter of 10 mm. The acceleration in the nozzle contraction was used to separate the fibre floes in the Suspension making them move individually, thus making the visualisations easier. To avoid the problem of floc break-down at nozzle exit when using a conventional linear nozzle with parrot's beak outlet, two Curved contraction blocs were inserted, giving a more constant acceleration profile, letting the floes keep their integrity in the emerging jet. The high speed video system had two main arrangements, for the Study of floc behaviour in the forming zone. A mirror installed on the machine structure visualised a certain area of the forming zone. Alternatively, a mirror fastened to the back plate of the forming roll followed a specific area of the wire (and roll), making it possible to follow the floes through the entire forming zone. It is then possible to detect any relative motion between floes and wire.

Effects of natural winter browsing and simulated summer browsing by moose on growth and shoot biomass of birch and its associated invertebrate fauna
- 2009
-
In: Annales Zoologici Fennici. - : Finnish Zoological and Botanical Publishing Board. - 0003-455X .- 1797-2450. ; 46, s. 63-74

Journal article (peer-reviewed)abstract
- Plant responses to mammalian herbivores can be manifold. Browsing by large mammals such as moose may change plant growth and morphology, which, in turn, will change the food quality and availability for e.g. invertebrate herbivores sharing the same forage plant. Furthermore, the intensity and timing of herbivory may affect plant responses and future herbivore attack. In a field experiment, we tested whether simulated summer browsing and natural winter browsing by moose affects growth and morphology of birch Betula pendula, and whether possible changes had effects on abundance and defoliation by herbivorous invertebrates. The simulated summer browsing treatment was applied in two intensities (50% and 100% defoliation of long shoots) during two different periods of the growth season (mid-June and mid-July). Simulated summer browsing delayed the timing of budburst, reduced height and diameter growth and resulted in reduced defoliation by invertebrate herbivores indicating an induced defence. Winter browsing by moose reduced diameter growth, leaf biomass of short shoots but increased height growth, the abundance of aphids and defoliation by insect herbivores. The effects of herbivory on the timing of budburst, leaf biomass of long and short shoots and the abundance of aphids were more pronounced when the birches were both browsed in winter and artificially stripped. The timing of the artificial leaf stripping treatment was important for nearly all tested variables. Concluding, summer and winter browsing by moose can have opposing or additive effects on plant morphology and growth. Therefore, also indirect effects of mammalian herbivory on invertebrate communities feeding on the same plant may differ, depending on the browsing intensity, the season of browsing and even the timing of browsing within the same season.

Fibre flocculation during twin-wire roll forming
- 2003
-
Licentiate thesis (other academic/artistic)abstract
- At the division of Paper Technology a forming unitconsisting of headbox, forming roll unit and reservoir systemfor suspension recirculation has been constructed, with themain purpose to experimentally study the paper forming event byvisually following the fibre flow phenomena in the formingzone.The effect of various running parameters upon the pressuredistribution, which is in correlation to the flow phenomenaoccuring during forming, has been studied with a flush mountedpressure sensor. Some combinations of running parametersresulted in highly oscillating pressure pulses, which wereevaluated by their wavelength.The visualisation was made with a high-speed video cameraand a pulsed laser light source. The forming zone was observedvia a mirror mounted on the forming roll, thus following aspecific small area of the forming zone. This made it possibleto follow floc motions relative to the forming roll/wire. Theflocs were found to move towards the wire due to the dewateringflow wereupon the bottom part of the floc was pinned to thewire. If the suspensionspeed is different from the wire speedthe floc will be stretched out, because the upper part of thefloc has a slightly different speed in comparison to the bottompart. If this speed difference is high enough, the flocs maysplit and thus contribute to fragmentation.The floc-floc interaction has been studied in a Couetteapparatus. It has been observed that voids in the suspensionplay a central role for the floc break-up process. The reasonis belived to be that voids induce movement inside thesuspension, which is a prerequisite for floc break-up. Thefloc-floc relative movements have been found to obey simplelaws of rack-and-pinion principles.

Fibre flow mechanisms
- 2005
-
Doctoral thesis (other academic/artistic)abstract
- The flow behaviour, and primarily the floc-floc interaction, of pulp paper suspensions have been studied visually. Analogy models based on these observations have been developed as well as the identification of important parameters of floc break-up in low shear rate flow fields. Floc compressions and the locations of voids (areas of lower fibre concentration) where found to influence the floc splitting mechanism. Based on this investigation an equipment for measuring the load carrying ability of fibre flocs and networks was designed, and the effect of measurement geometry, network structure and fibre suspension concentration was investigated. The load carrying ability with concentration increases rapidly when going from 1% to 2% in initial suspension concentration. A model handling the fibre floc behaviour during extension and compression has been developed, and some basic flocculated flow mechanisms are discussed on an analogy basis. A modified Voigt element is use, describing mainly the compressional behaviour and plastic behaviour of loose fibre network structures. Further the pos- sibility of stress chain formation is discussed on a fibre level as well as on a floc level. The effect of fibre flow (shear field) occurring in the forming zone of a roll former has been studied in detail. Basic forming mechanisms on floc scale has been investi- gated, and the effect of running parameters like dewatering pressure and jet-to-wire speed difference as well as the fibre type and concentration of the pulp suspension has been evaluated. It is evident that floc elongation increases with shear rate (jet-to-wire speed difference) and lower dewatering rate. The latter is because the fibre floc is subjected to the shear field longer due to slower immobilisation. Shorter fibre tends to create weaker networks, which promotes a higher elongation of the flocs.

Impacts of moose (Alces alces) at different simulated densities on eco-morphological groups of soil mesofauna
- 2010
-
In: Entomologica Fennica. - 0785-8760. ; 21, s. 168-180
-
Journal article (peer-reviewed)abstract
- We experimentally tested the impact of browsing, defecation and urination corresponding to four different levels of moose population density on abundance and number of eco-morphological groups of soil mesofauna in a Swedish boreal forest. The study was carried out in three fenced exclosures representing different levels of productivity (from nutrient-rich to nutrient-poor). Moose impact on soil communities was evaluated by analysing abundance, richness and diversity of mesofaunal groups, and by means of a multi-taxa index based on ecomorphological groups, the Biological Soil Quality index (QBS). There was a negative impact of high moose densities on the abundance and richness of soil mesofauna. Furthermore, low-moderate moose densities had a positive impact on abundance and number of eco-morphological groups. We conclude that moose can have a large impact on soil-living mesofauna, and therefore probably soil decomposition processes and biological soil quality, in young boreal forest stands.

Journal article (peer-reviewed)abstract
- Spines in plants have evolved to reduce mammalian herbivory, and their main function may be to protect twigs more than photosynthetic tissue. Type and frequency of spines vary at different scales. We hypothesised that different types of spines affect animal foraging through different mechanisms. We studied feeding behaviour by twig-browsing goats in relation to two types of spines of Acacia tortilis using experimental manipulation of the occurrence of spines. Feeding time, number of biting actions, number and diameter of bites on trees (post-trial) and total intake were recorded. The removal of either long straight spines or short hooked spines resulted in no feeding responses by goats. The removal of both types of spines tended to increase feeding time resulting in more and larger bites with larger bite diameters and in increased total intake and utilisation compared to control branches. The removal of spines had no effects on feeding rate, expressed as biting actions per minute, number of twigs bitten per minute or intake rate (grams per minute). Both types of spines reduced total intake and utilisation of browse, but the functional mechanisms were different with the long straight spines mainly influencing bite size and short hooked spines mainly affecting number of bites.

Anti-browsing effects of birch bark extract on fallow deer
- 2013
-
In: European Journal of Forest Research. - : Springer Science and Business Media LLC. - 1612-4669 .- 1612-4677. ; 132:5-6, s. 717-725

Journal article (peer-reviewed)abstract
- A major problem within forest industry is unwanted browsing on seedlings from mammalian herbivores. The aim of this study was to evaluate the effects of birch bark extracts as repellents towards fallow deer. Birch bark was extracted in a conventional way with ethanol as solvent at ambient temperature and with a new method, liquid CO2 extraction. An analysis of the ethanol-extracted birch bark showed that it contained large amounts of terpenoids, of which the most abundant was betulin. In seven different treatment trials, we used 15 individually handled fallow deer. To investigate the binary taste preferences, birch bark extract was added to food and presented in two bowls in typical two-choice tests. We found that the amount of a food type consumed during a trial and the number of shifts between food bowls were dependent on the amount of the birch extract the food contained. Concentrations of above 1 % by dry weight of birch extract acted as a repellent. In addition, such concentrations produced shorter feeding bouts by a greater willingness to change bowls. Therefore, our conclusion is that birch bark extract acts as a repellent towards fallow deer and is therefore likely to act as a repellent against other deer species. In addition, we show that birch bark extract produced by the new and more environmentally sustainable method employing liquid CO2 mixed with ethanol has the same repellent effect as the traditional ethanol extraction.

Mapping potential location for bilberry picking with remote sensing, local field data andphone application
- 2023
-
Conference paper (other academic/artistic)abstract
- The aim of the study was to create a practical method for identifying potential locations for bilberry picking with help of remote sensing, local field data and phone application to support the development of the local berry value chain. Local field data w as collected 2021 and 2022 and consisted 503 and 525 plots from a study area of circa 25x45km in Västerbotten, Sweden. The potential for bilberry production was evaluated by measuring the shrub cover and amount of raw berries. Wall to wall remote sensing d ata included a Sentinel 2 image from same summer, airborne laser scanning data from 2020 and other map products. We created classification models for bilberry shrub and yield using both logistic regression (2 classes) and ordinal regression (3 classes) mod els using 2021 data, and validated and calibrated models with 2022 data. Predictor variables consisted of spectral metrics from satellite data; structural metrics from laser data; existing raster maps of tree species, stand attributes, site index, soil moi sture and land use classes. The 2 class models performed better than three class models, delivering the AUC 0.73, overall accuracy 0.83 and kappa value 0.51 for best bilberry shrub model and 0.75, 0.77 and 0.50 respectively for best bilberry yield model. T he best models included both laser based structural metrics describing e.g canopy closure and spectral metrics, but also e.g. volume of pine, soil moisture and site index were found significant predictor variables. Calibration of the models improved annual predictions and the validation of the 2021 raster maps with 2022 data produced similar AUC, OA, and kappa values for bilberry yield (0.73, 0.74 and 0.46), but lower for bilberry shrub (0.61, 0.68 and 0.24). A dedicated phone application was developed duri ng the project, which was used both for collecting the field data and for presenting the potential locations of berry yields. Local berry maps can help berry pickers easier to find the berries in forest landscape and therefore support local berry value cha in. This study is part of the FAIRCHAIN project, which has received funding from the European Union’s funding programme H2020 research and innovation programme under grand agreement 101000723.
