1 Lennart Nilsen -3 studenter Prosjekt/Project 1. Spredning av innførte plantearter, -en komparativ studie av Vårpengeurt (Noccaea caerulescens) og Tromsøpalmen (Heracleum persicum). I dette masterstudiet skal spredningsmønster til vårpengeurt og tromsøpalmen analyseres i tid og rom ved bruk av geografisk informasjonssystem (GIS). Informasjon fra Universitetsmuseenes herbariedatabase skal kobles sammen med geografisk temadata i GIS. I tillegg skal det samles inn data om fordeling av artene på tromsøya og omkringliggende områder. Formålet med studiet er å forsøke å avdekke spredningsmønster og hastighet til artene, samt prøve å identifisere hovedbetingelser som bidrar til spredning av artene. Studiet kan passe som et samarbeidsprosjekt for 2 masterstudenter. The spread of introduced plant species, a comparative study of alpine pennycress (Noccaea caerulescens) and hogweed (Heracleum persicum). In this master study spread pattern of alpine pennycress and hogweed will be analyzed in time and space through the application of geographic information system (GIS). Information from Tromsø museum herbaria database will be linked with other thematic data layers in GIS. In addition, distribution pattern of the species will be mapped in detail on Tromsøya and the surrounding areas. The purpose of the study is to analyze spread pattern and speed of the species, and try to identify the main conditions that contribute to the spread of the species. The program can fit as a joint project for two master's students. Veiledteam/Superviser team: Dr. Lennart Nilsen, Dr. Inger G. Alsos and Dilli Prasad Rijal (PhD.). Prosjekt 2. Anvendelse av fjernmålingsteknikk for å dokumentere plantenes fenologiske utvikling: En studie av interaksjon vegetasjon-miljø ved hjelp av et fastmontert digitalt kamera og feltbasert innsamling av floristiske data. Formålet med prosjektet er å (1) beskrive hvordan fysiske betingelser som lengden av snødekke, temperatur og jordfuktighet bestemmer plantesamfunnenes romlig fordeling og de sesongmessige mønstre i plantenes fenologisk dynamikk. (2) anvende fjernmålingsdata for å klassifisere plantesamfunn og overvåke plantefenologi på landskapsnivå. Application of remote sensing techniques to track phenologic events: Studying vegetationenvironment interaction using a mounted digital camera and floristic field sampling on Svalbard, High Arctic.

2 The project aims are to (1) describe how annual physical conditions like duration of snow cover, temperature and soil moisture determines the plant community spatial distributions and seasonal pattern of plant phenology dynamics (2) apply remote sensing data for plant community classification and monitoring plant phenology at landscape level. Veilederteam/Supervisor team: Dr. Lennart Nilsen, Dr. Elisabeth Cooper and Philipp Semenchuk (PhD.) Prosjekt 3. Snødekkets betydning for plantediversitet i det alpine landskap. Prosjektets hovedmål er å studere sammenhengen mellom geografisk fordeling av plantediversitet og snømengde i det alpine landskapet i Troms fylke. Prosjektet vil gjøre utstrakt bruk av geografiske informasjonssystem (GIS) og satelittbasert fjernmålingsdata. Samtidig er det en fin anledning til å bli kjent med fjellfloraen i fylket. Prosjektet kan tilpasses en eller to masterstudenter, for eksempel med en sammenlignende studie på Svalbard. Snow covers impact on plant diversity in alpine landscapes. The main purpose is to study the relationship between geographical distribution of plant diversity and snow cover duration in mountain areas of Troms County. The master project relies heavily on the use of geographical information system (GIS) and satellite based remote sensing data. This is also a good opportunity to get known with the alpine vascular flora of Troms County. The design can be fit as a joint project for two master's students, for instance as a comparative study with areas on Svalbard. Veileder/Supervisor: Dr. Lennart Nilsen Vera Hausner 2-3 studenter Master thesis: Greening and grazing of the arctic tundra: a remote sensing study With climate change the growing season in the arctic tundra is getting longer and warmer. As a consequence, willow shrubs are predicted to expand and the forest is predicted to move northwards. Increased growth of willow thickets has been documented in several places in the Arctic, notably in Alaska. Shrub expansion and greening may however be counteracted by intense grazing. Semidomestic reindeer are numerous in some tundra areas and have a considerable impact on the vegetation, limiting growth and reducing the extent of willow shrubs. Grazing has also been shown to affect the tree-line. In this thesis we propose to analyze changes in the extent of willow thickets and the forest tundra transition during in the areas surrounding a set of model settlements. Historical aerial and high resolution satellite photographs ( Corona images ) will be compared with present day

3 high resolution satellite images to identify changes, which will be related to different grazing regimes and climatic zones. This thesis will be a part of the project TUNDRAscape (terrestrial flagship of the Fram centre) and of the project TUNDRA ( TUNDRA is an interdisciplinary and international project aiming at determining how governance systems and socioeconomic conditions in arctic regions determine direct human impact on the tundra ecosystem and the services it provides to local residents. TUNDRAscape uses remote sensing to investigate how grazing regime, present habitat transformation and historic use together with climate determine vegetation states in areas surrounding 34 settlements situated in the tundra or forest tundra regions of Norway, Russia, Alaska and Canada. Veilederkomité/Supervisor team: Dorothee Ehrich (AMB), Vera Hausner (AMB), Hans Tømmervik (NINA) og Per Fauchald (NINA) Project MAP- Forvaltning av alpine verneområder 1-2 masterstudenter kan tilknyttes prosjektet MAP. Dette er et prosjekt som har som formål å utvikle metoder for overvåkning og evaluering av alpine verneområder. Studenter kan jobbe med datamateriale som er innsamlet fra 11 parker i Norge, eventuelt koble det med fjernmåling eller innsamling av feltdata fra et begrenset utvalg av parker. Denne delen av MAP gjøres i samarbeid med Lorena Munoz som skal jobbe med disse dataene høsten MAP prosjektet inneholder også en del som kan utvides til sammenliknende forvaltningsanalyse av alpine områder i andre land. Prosjektbeskrivelse utformes i samarbeid med hovedveileder, Vera Hausner. Eventuelle biveiledere vil avhenge av studentens målsetninger med oppgaven. Project MAP- Management of protected areas in Alpine areas (MAP) 1-2 masterstudents could work on the project MAP which aims to develop methods for monitoring and evaluation of alpine protected areas. Students could work with the data material already collected in 11 parks in Norway, or combine the data with remote sensing or field data in a smaller sample of the parks. The student will collaborate with Lorena Munoz who will also work with these data. Parts of MAP could also be extended to alpine areas in other countries for comparative analysis of protected areas management. Project description will be developed in collaboration with the main supervisor, Vera Hausner, and assistant supervisors will be included depending on the students interests.

Students should contact the project leader Ingunn Tombre (ingunn.tombre@nina.no) and Einar Eythorssen, who would develop the project in cooperation with the student. Vera Hausner is the main supervisor at AMB. Rolf Ims 1 student Responses of passerine bird communities to geometrid moth outbreaks Aim: The mountain birch forest of northern Fennoscandia is regularly ravaged by intense outbreak of geometrid moth larvae that may completely defoliate the trees. These outbreaks seem recently to have become intensified by a warmer climate. How this affects biodiversity has yet been little explored. In this project we will investigate how the community of passerine birds responds to such outbreaks by comparing forest affected and unaffected by moth outbreaks. Point transect methodology will be used to census the bird communities and recent developments within probabilistic habitat occupancy modeling will be used to estimate species-specific occupancy rate and community level species richness. Field work will be conducted in June in the vicinity of Tromsø in areas where there are presently an ongoing moth outbreak. Requirements: The student need to have good prior experience in identifying bird species based on the songs/calls. Main supervisor: Rolf A. Ims Ivar Folstad 1-2 studenter Jeg har oppgaver innen adferdsbiologi og evolusjonær psykologi.
