För den som vill fiska i Strömmen är det bara att ta sitt fiskespö och gå dit, fisket har varit fritt för allmänheten sedan 1436. Men sportfisket är inte okontroversiellt, all lax och öring i Strömmen är inplanterad och hotar de naturliga fiskbestånden i länet. Och man bör akta sig - fiske kan vara beroendeframkallande.

Ammerån which is a small forest river in eastern Jämtland is a well-known river that has been a popular fishing river for a long time. The actual Ammerån begins downstream the lake Solbergsvattnet at Hammerdal and flows into the Indalsälven 10 km upstream Hammarstrand. The river environment switches between forests with wilderness feeling and open agricultural land. The entire Ammerån is today a nature reserve and protected from hydropower development. Fishing in Ammerån has mainly been focused on trout and grayling, and is so even today. There are many indications that the grayling and trout stocks declined if compared to the data since the mid 1900’s. There are two major reasons to that the fish are reduced in number and size that I can see. One is the cleanup of the river for rafting in the early 1900’s where man simply excavated and dug out of the river into a canal with even waterflow and also blew away a lot of rock. The other reason is forestry industrialization from the late 1950’s and onwards which meant that many of the trout’s spawning creeks where destroyed. Also the increased fishing pressure would have made the fishing in the river worse. The fishing for pike and other fish in the calm areas of the river that is wintering areas for salmonids has decreased a lot and that may also have contributed to the decline in populations of grayling and trout.Today, Ammeråns ecological status shall be considered as relatively good. Samples from SLU's sampling station shows that the pH value is high and has been since records began in 1966 and the chemical quality is in general very high. The number and density of insects and other aquatic organisms that is food for grayling and trout is quite high.Ammerån has been restored to look like it did before the rafting, and one has posted stone to create habitat for the fish and restore the river to what it looked like before the rafting period. Some of Ammeråns tributaries that was cleared for rafting has been restored and spawning areas has been made for the trout. Within these two fields there is still much to be done and I will make suggestions for further recovery actions.Ammerån has great potential to develop as a fishing river. The river is already visited by a lot of fishing tourists, but many find that the stocks of trout and grayling are sparse and small in stature. Studies show that with change in regulations and habitat care it would be possible to make Ammerån a fishing water of much higher quality than today, with both more and larger fish. Higher quality of fishing would make Ammerån even more popular to fishing tourists and would make them willing to pay more to fish there. This would make it possible to provide even better service to the anglers and provide income to the area. In this report I want to suggest both biotope conservation measures and fishing regulations that has demonstrated good efficacy in populations of grayling and trout in running water.

Drönarteknik inom skogsuppskattning blir allt vanligare. Klave har alltid varit det vanliga verktyget att använda för diametermätning i brösthöjd av träd. Ny teknik har gjort det möjligt att mäta brösthöjdsdiameter genom att filma träden med drönare. Från filmen skapas ett skalenligt tredimensionellt punktmoln där brösthöjdsdiameter kan utvinnas, processen kallas för videogrammetri. Denna studie undersöker precisionen hos diametermätning genom videogrammetri från drönare.

I skogsplantskolor har styrolit länge använts som täckmaterial på nysådda plantor. Styroliten skyddar fröet och gör så att torven behåller fukten bättre. Styrolit har en baksida, det är ett icke förnybart material tillverkat av olja och materialet följer med plantorna ut i skogen. Ersättare för styrolit finns men dess effekt på plantproduktionen är inte helt kartlagd. Syftet med denna studuie var att jämföra effekterna av styrolit och sågspån som täckmaterial och se vilken påverkan de har på grobarhet, tillväxt och vitalitet. Resultatet av studien visade att täckning med sågspån gav en bättre total grobarhet än täckning med styrolit. Studien visade också att höjdtillväxten hämmas av ett tjockare sågspånslager. Indikationer fanns på att grövre fraktioner av sågspån gav bättre tillväxt hos tall än täckning med finare fraktioner.

O objetivo específico desta dissertação é comparar dois programas de pesquisa rivais que descrevem a cognição social conforme a teoria de Fiske. Duas explicações diferentes sobre a Teoria dos Modelos Relacionais de Fiske são apresentadas por dois programas de pesquisa concorrentes. O primeiro, defendido por Bolender, incorpora campos da física, biologia, filosofia da linguagem e entende que, sendo as quatro escalas de medida fundamentais para as quatro formas elementares de sociabilidade, é possível que elas tenham origem em um gerador central de padrões único. O segundo, defendido por Favre e Sornette, utiliza matemática e lógica para mostrar como podem surgir as quatro formas elementares de sociabilidade sem fazer menção às quatro escalas de medida. Utilizaremos metateorias filosóficas para avaliar ambos programas de pesquisa. A importância de avaliar os dois programas consiste em um esforço no sentido de aprofundar o entendimento acerca da Teoria dos Modelos Relacionais. / The main goal of this dissertation is to study the theory about human sociability according to Fiske. The specific goal of this dissertation is to compare two rival research programs that describe the social cognition as defended by Fiske. Two different explanations about the Relational Models Theory from Fiske are presented by two rival research programs. The first, defended by Bolender, incorporates fields from physics, biology, philosophy of language and states that, being the four measurement scales fundamental to the four elementary forms of sociality, it is possible that they have its base on a central pattern generator. The second, defended by Favre and Sornette, utilizes math and logic to show how the four elementary forms of sociality appear and does not mention the four measurement scales. We will apply philosophical metatheories to evaluate both research programs. The importance of evaluating both programs consists in an effort towards deepening the understanding of the Relational Models Theory.
