Spatial and Temporal Dynamics of Human–Wildlife Conflicts in the Kenya Greater Tsavo Ecosystem
(Peer reviewed; Journal article, 2020)Biodiversity conservation in developing countries is faced with many and mounting challenges, including increasing human–wildlife conflicts (HWCs). In Africa and other developing countries, increasing HWCs, particularly ... -
Spatial and Temporal Genetic Structure in Landrace Cereals
(Doctoral thesis at NTNU;2015:37, Doctoral thesis, 2015)Genetic variation exists both on a geographical and a temporal scale. By tracing patterns in variation through time and space it is possible to explore the history of species. Since domestication, crop plants have diverged ... -
Spatial and temporal genetic structure of a river-resident Atlantic salmon (Salmo salar) after millennia of isolation
(Journal article; Peer reviewed, 2014)The river-resident Salmo salar (“småblank”) has been isolated from other Atlantic salmon populations for 9,500 years in upper River Namsen, Norway. This is the only European Atlantic salmon population accomplishing its ... -
Spatial and temporal variation in herbivore resources at northern latitudes
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:144, Doctoral thesis, 2007)Herbivores may affect plants directly through foraging, trampling and fertilization or indirectly through altered competitive relationships between plant species. In addition, herbivores may cause indirect interactions ... -
Spatial and temporal variation in hippoboscid parasitism by Ornithomya chloropus on house sparrows (Passer domesticus) and its effect on survival
(Master thesis, 2013)1. I examined how the Hippoboscidae Ornithomya chloropus is spatially and temporally distributed in an insular metapopulation of house sparrows in northern Norway from 2004-2011, whether there were demographic differences ... -
Spatial and Temporal Variation in Moose- (Alces alces) Road Crossings
(Master thesis, 2012)This study examined what separates a crossing site from an available crossing site and investigate when and where roads are more likely to be crossed by moose (Alces alces). Five seasonal models for two sexes were selected ... -
Spatial assessment of ecosystem services in Ghana: Using an ethnobotanical approach
(Master thesis, 2019)Ecosystem services support countless livelihoods worldwide. These include the provisioning of medicines, food, fuelwood, livestock fodder, building materials and cultural artefacts that have been documented in ethnobotanical ... -
Spatial consistency in drivers of population dynamics of a declining migratory bird
(Peer reviewed; Journal article, 2022)1. Many migratory species are in decline across their geographical ranges. Single-population studies can provide important insights into drivers at a local scale, but effective conservation requires multi-population ... -
Spatial consistency in drivers of population dynamics of a declining migratory bird
(Peer reviewed; Journal article, 2022)1. Many migratory species are in decline across their geographical ranges. Single-population studies can provide important insights into drivers at a local scale, but effective conservation requires multi-population ... -
Spatial covariation of competing species in a fluctuating environment
(Journal article; Peer reviewed, 2020)Understanding how stochastic fluctuations in the environment influence population dynamics is crucial for sustainable management of biological diversity. However, because species do not live in isolation, this requires ... -
Spatial cumulant models enable spatially informed treatment strategies and analysis of local interactions in cancer systems
(Peer reviewed; Journal article, 2023)Theoretical and applied cancer studies that use individual-based models (IBMs) have been limited by the lack of a mathematical formulation that enables rigorous analysis of these models. However, spatial cumulant models ... -
Spatial distributions and productivity in salmonid populations
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:235, Doctoral thesis, 2013)This thesis presents analysis and fieldwork investigating how the effect spatial distributions and spatial relationships have on population growth in two anadromous salmonid species, Atlantic salmon and brown trout. The ... -
Spatial Ecology of Wolverines in Scandinavia
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:161, Doctoral thesis, 2007) -
Spatial genetic structure in Northern European Sphagnum squarrosum Crome in relation to its Arctic morph
(Master thesis, 2021)Den arktiske morfen til Sphagnum squarrosum skiller seg fra den typiske Boreale morfen og har morfologiske likheter med S. teres som er nært beslektet og kan ligne på S. squarrosum når den vokser under spesifikke forhold. ... -
Spatial heterogeneity in climate change effects decouples the long‐term dynamics of wild reindeer populations in the high Arctic
(Journal article; Peer reviewed, 2019)The ‘Moran effect’ predicts that dynamics of populations of a species are synchronized over similar distances as their environmental drivers. Strong population synchrony reduces species viability, but spatial heterogeneity ... -
Spatial patterns and drivers of the functional diversity of cannrivore communities in the Arctic
(Master thesis, 2021)Å kunne forstår diversitetsmønsteret og hvilke faktorer som driver disse er avgjørende for å bedre kunne forutsi økosystemets respons til tap av biodiversitet og klimaendringer. Artsrikhet har tradisjonelt blitt brukt i ... -
Spatial patterns of phylogenetic diversity of Mexican mammals for biodiversity conservation
(Master thesis, 2020)Phylogenetic diversity (PD) is a biodiversity measurement that describes the total amount of evolutionary history contained by the taxonomic units in a particular region. PD has proven to be an important metric for determining ... -
Spatial scales of population synchrony in predator-prey systems
(Peer reviewed; Journal article, 2020)Many species show synchronous fluctuations in population size over large geographical areas, which are likely to increase their regional extinction risk. Here we examine how the degree of spatial synchrony in population ... -
Spatial scaling of population synchrony in marine fish depends on their life history
(Peer reviewed; Journal article, 2019)The synchrony of population dynamics in space has important implications for ecological processes, for example affecting the spread of diseases, spatial distributions and risk of extinction. Here, we studied the relationship ... -
Spatial structure and dispersal dynamics in a house sparrow metapopulation
(Peer reviewed; Journal article, 2021)The effects of spatial structure on metapopulation dynamics depend upon the interaction between local population dynamics and dispersal, and how this relationship is affected by the geographical isolation and spatial ...
