Using the satellite-derived NDVI to assess ecological responses to environmental change.
The use of the NDVI in recent ecological studies is reviewed and its possible key role in future research of environmental change in an ecosystem context is outlined. Expand
Review article. Studying climate effects on ecology through the use of climate indices: the North Atlantic Oscillation, El Niño Southern Oscillation and beyond
This work identifies issues related to: (i) spatial variation; (ii) seasonality; (iii) non–stationarity; (iv) nonlinearity; and (v) lack of correlation in the relationship between global and local climate. Expand
Ecological Effects of Climate Fluctuations
This work reviews how two of the best-known climate phenomena—the North Atlantic Oscillation and the El Niño–Southern O oscillation—affect ecological patterns and processes in both marine and terrestrial systems. Expand
This work investigated the influences of large-scale climatic variability on plant phenology and ungulate population ecology by incorporating the NAO in statistical analyses of previously published data on the timing of flowering by plants in Norway and phenotypic and demographic variation in populations of northern ungulates.

Ecological mechanisms and landscape ecology
This work presents an approach to research that focuses on how individual-level mechanisms operating in a heterogeneous mosaic produce ecological patterns that are spatially dependent. Expand
Linking climate change to lemming cycles
It is shown that winter weather and snow conditions, together with density dependence in the net population growth rate, account for the observed population dynamics of the rodent community dominated by lemmings in an alpine Norwegian core habitat between 1970 and 1997, and predict the observed absence of rodent peak years after 1994.

Population cycles in voles and lemmings : density dependence and phase dependence in a stochastic world
It is concluded that multiannual population cycles seen in voles and lemmings will continue to be a strong source of conceptual and methodological developments within the field of population ecology. Expand
Bush cover and range condition assessments in relation to landscape and grazing in southern Ethiopia
Progressive growth of bush cover in dry savannahs is responsible for declines in range conditions. In southern Ethiopia, the Booran pastoralists assisted our understanding of spatial patterns of bushExpand
Fine‐scaled geographical population structuring in a highly mobile marine species: the Atlantic cod
Findings lend support to the notion that low levels of differentiation are due to passive transport of eggs or larvae by the ocean currents rather than to adult dispersal, the latter being strongly dependent on distance. Expand
Trait changes in a harvested population are driven by a dynamic tug-of-war between natural and harvest selection
This is the first study to demonstrate that a consideration of both natural selection and artificial selection is needed to fully explain time-varying trait dynamics in harvested populations. Expand
