Freshwater pearl mussel as indicators of Swedish streams - a comparison between freshwater pearl mussel and biological quality elements

The freshwater pearl mussel (Margaritifera margaritifera) is a large freshwater mussel. Because of its sensitivity to human impact, such as eutrophication, acidification and alterations of hydromorphology, the species is considered as a robust indicator of stream water quality and biodiversity. Moreover, due to the species complex life cycle, including a larval stage on the gills of salmon and trout, and sensitivity of early life stages, regeneration is often used as an indicator. The freshwater pearl mussel is also used in the expert judgement of status classification of benthic invertebrates according to the European Water Framework Directive. The purpose of this study was to gain a deeper understanding of the freshwater pearl mussel as an indicator for Swedish streams. It was made with two types of association analyses.

Löpmagsförskjutning hos mjölkkor : en besättningsutredning för att identifiera riskfaktorer för metaboliska störningar

The purpose of this study was to find possible explanations to why the studied herd had an increased incidence of abomasal displacements. The incidence of abomasal displacement in the herd was three times higher than the incidence of an average Swedish herd. The cows in this study were fed a total mixed ration. The different parameters studied were: energy content in food, nutritional content in food, body condition scoring, concomitant other diseases, and blood parameters of glucose, fructosamine, cholesterol, insulin, betahydroxybutyrat and free fatty acids. The author?s suggestions to decrease the problems are to decrease the energy content in the TMR to lower the cows? body condition scores in the dry period and changing the content in the TMR to increase the amount of NDF and adding structure in the form of chopped straw.

Use of dogs as odour detectors : a review of the scientific literture

A lot of various substances can be detected by dogs, as oestrous in cows, endangered species or non-biological substances like accelerants, narcotics, explosives, mines and pollutions and biological substances like identity (suspects), cancer (breast, lung, colorectal and bladder cancer), human remains (cadaver), bacteria and mould in buildings. The dogs are trained using non-scientific methods and not much research in detection training exists. This is a review of different types of dog detection, with focus on new research..

Ajuourhållning av ungskogsdata med hjälp av digitala flygbilder :

The purpose of this study is to investigate whether it is possible for SCA to update their stand register with use of digital aerial photos photographed with a Zeiss/Intergraph DMC. ?Updating? in this study implies the delineation of stands and estimating stand variables such as average stand height, volume density, stand volume, and tree species composition in order to identify stands which can be of current interest for thinning. The study also includes how the aerial photo material and experience of the interpreter can influence the quality of the interpreted variables. The aerial photo interpretations were made by both experienced and inexperienced interpreters.

Rådjur (Capreolus Capreolus) på Gotland : populationsutveckling och spridningsmönster

Gotland is an island in the Baltic Sea where man has introduced roe deer. The last successful reintroduction was in the 1980s and is the base of the viable roe deer population of today.The aim of this study was to estimate the roe deer population density in 2012 and the species population dynamic since the time when studies on the population started. The result indicates a population size of 850 roe deer in 2012. There was no significant population dynamic, which may be due to insufficient data. The population occurs basically over the whole island but have not yet been established in all suitable areas.

Habitat preferences and reproductive success forthe threatened longhorn beetle Plagionotusdetritus

Plagionotus detritus is a threatend longhorn beetle that only exists at one site in Sweden. It is saproxylic and depending on recently dead coarse oak wood for its larval development. Trees at Djurgården, Stockholm that have been colonized by Plagionotus detritus has been studied 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 success was measured in two ways, the larval mortality and the size of the hatching holes.

Effekter av predationsrisk på sånglärkors (Alauda arvensis) habitatval på åkermark

Along with other European farmland birds, the skylark (Alauda arvensis) has declined rapidly since the 1970?s. Between 1975 and 2003, the Swedish population of skylarks declined with 64 %. In Britain, the decline is often explained by alterations in farming practices in general and the shift from spring-sown to winter-sown cereals in particular. The dense vegetation structure of winter cereals is limiting the number of breeding attempts possible, causing the entire population to decline.

Nätverkskommunikation för jämställdhet

AbstractTitle: Network communication for equal opportunities (Nätverkskommunikation för jämställdhet)Number of pages: 47 (54 with enclosures)Author: Hillevi GoodTutor: Ylva EkströmCourse: Media and Communication Studies DPeriod: Spring Semester 2007University: Division of Media and Communication, Department of Information Science, Uppsala UniversityAim: The aim of this essay is to study the possibilities to bring about change by the means of communication in two networks, focusing on the implementation of the Swedish Equal Opportunities Act.Material and method: The study draws on data collected in an electronic survey among representatives of two networks consisting of representatives from trade unions and employer?s associations. The material is analyzed using descriptive tools, cross tables and correlation matrices in which general characteristics as well as individual understandings of the network communication are presented and discussed.Main results: The general results indicate that the network communication serves important purposes, such as providing support and motivation for the members and changing attitudes towards equal opportunities. The analysis suggests that the network members have good communicative possibilities to serve as agents of change within their organisations. Moreover, there is an observed relation between, on the one hand, organizational context and, on the other hand, the network members? own communicational behaviour and their experienced possibility to influence their organizations.Keywords: network communication, diffusion of innovations, behaviour change, Equal Opportunities Act.

Fodrets inverkan på resultatet vid undersökning av förekomst av ockult blod i avföringen hos hund :

Hemoplus® (Sarstedt, Nümbrecht, Tyskland) is a guaiac-based fecal occult blood test developed for human medicine. Guaiac-based tests make use of the pseudoperoxidase activity of hemoglobin so the test is not specific for human hemoglobin and can therefore be used in veterinary medicine. Peroxidase-containing foods such as meat (hemoglobin and myoglobin) can cause false-positive results of the test. To ensure that a positive result is not caused by diet, it has been suggested that canine patients should be fed a meatless diet for a few days prior to fecal occult blood testing. The aim of this study was to evaluate the effect of commercial dog food on guaiac-based tests. In this study fecal samples from healthy dogs were analyzed with Hemoplus®.

The age division is quite even with one peak at the turn of the century, one during the ?60s and another during the ?90s.

Strategier vid generationsskifte : ekonomiska implikationer för olika intressenter

A large number of farms within the agricultural sector will shortly be facing a point of time where the farm will be transferred to the next generation. The grantor can choose between totally 8 different strategies to transfer the farm, of which purchase, gift and a mixed form of these are the most common. During 2007 almost 10 000 transfers of agricultural estates occurred in Sweden and the expectation for the coming years is that about 15 000 estates will be transferred each year. By the time a transfer is about to materialize there are usually several stakeholders that in one way or another is trying to influence the outcome of the transfer. The choice of transfer method affects the conditions and possibilities for compensating the siblings.
