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.

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.

It is proposed that theNAO effects may be classified as three types: direct, indirect and integrated, which will help the design and interpretation of analyses attempting to relate ecological changes to the NAO and, possibly, to climate in general.
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.
CLIMATIC VARIABILITY, PLANT PHENOLOGY, AND NORTHERN UNGULATES
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.

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.
North Atlantic Oscillation timing of long‐ and short‐distance migration
Summary 1 The timing of migration is associated with survival and reproductive risks of migrating species. Hence, variation in factors influencing this timing, such as climate, may have…
The genome sequence of Atlantic cod reveals a unique immune system
The genome sequence of Atlantic cod is presented, showing evidence for complex thermal adaptations in its haemoglobin gene cluster and an unusual immune architecture compared to other sequenced vertebrates.
