påverkar tidigare jakt CPUE?
… harvest the first eight days affect CPUE the third four day period. Density estimates of willow ptarmigan were obtained from ten areas in the southern most hunted part of the Swedish mountain range. There was a significant but weak positive relationship between density and …
… to find out the habitat preferences of the species and to see what affects the density of beetles in a tree. The bark of some trees and wood from the breeding project at Nordens Ark has also been studied to find out what affects the species reproductive success. The reproductive …
… cannibalism is that the cannibal and the potential victim meet, and besides density effects, the encounter rate between cannibals and their victims is therefore also largely dependent on habitat use and habitat heterogeneity. In this study I quantified and compared the potential …
… tree stands had the same tree age, but the tree species combination and the density varied. The harwarder in the study was a Valmet 801 combi modified for whole tree harvesting. Ten study units were created in the tree stands, each study unit was 1250 m2. The average density …
kvaliteten på urbana habitat och om beståndstäthet är ett bra mått på habitatkvalitet
… A common method for measuring habitat quality is to calculate the population density. This method is easy to use, but have been criticized during the last couple of years. In this study, data of population densities was compared with data on reproduction success. The results …
… components of winter wheat vary depending on genotype, environment, sowing density and date of sowing.Seven varieties were grown in four locations in Sweden with three different sowing densities and with an early and a late sowing date. On each experimental site, the surviving …

… area, interest rate, the average income in the municipality, the population density in the municipality, if the purchaser exercises the option to hunt and the distance to the nearest road.The coefficient of determination for the final model of the interest group was 70.2% with …
… by UPM, all of the sites had been pre-commercially thinned. The mean stem density before harvest was 2578 stems per ha and the mean stem volume was 0.074 m3solid over bark.On average 1518 stems/ha was harvested. The mean tree size was 0.077 m3s of harvested stems, which …
… were emphasized in this study; the optimal water content and maximum dry density, as well as changes of both. As a reference for the limestone features, a traditional 0/32 mm tonalite material (granite) from Vällstaverket was used relating to proctor investigation. Material's …
… establishment. There is no significant correlation between the change in sheep density in relation to the shift in forest and tree limit. The shift in reindeer density did not correspond to the shift of forest limit, but to the shift in tree limit. However the coefficient of …
… three week period (1-21 April 2012) when the water temperature was low and the density of migrating diving ducks was high. The experimental cages used included three out of four different treatments; general predation (open cages), bird exclusion (net with mesh size 90*45mm) and …
… studies was conducted in addition to the field study. The variation in plant density, height and stem base diameter was analyzed. The results from this study suggested that seeded plants had a higher plant density than naturally generated plants but the difference was not …
What makes the Swedish wild boar reproduce more or less successfully?
… the rate of increase. The third hypothesis was that a higher people and hunter density would mean a lower rate of increase. Analyses were done on the 14 counties where there is an established wild boar population. The programs used to carry out the analyses were ArcMap …
… experimental design on the lime filter examines three different parameters, density of incoming lime mud flow, speed of the filter and wash water flow to the filter. Through the variation of these three variables in a calculated pattern an optimum can be obtained. There are …
… of health care and minimizing travel costs. Sweden’s low population density and geographical configuration makes the advantages of telemedicine even more appealing. To illustrate the differences between the county councils? use of telemedicine and thus increasing the possibility …
