The Arctic Tundra and adjacent Boreal Forest or Taiga support the most cold-adapted flora and fauna on Earth. The evolutionary capacity of both plants and animals to adapt to these thermally limiting conditions has always attracted biological investi

New sequencing technologies allow development of genome-wide markers for any genus of ecological interest, including plant genera such as Betula (birch) that have previously proved difficult to study due to widespread polyploidy and hybridization. We

Background: The fringe saltmarsh in the Eden Estuary is suffering severe erosion and its die-back will expose the shoreline to an increase in wave and tidal energy, especially given rising sea levels. Aims: To investigate the effect of vegetative tra

Proximity to the ocean can have both positive and negative effects for tree survival. Across the world relict forests that were once trans-continental in their distribution depend for their continued survival on coastal refugia. The tree species that

Summary Long-term survival is a feature of plant life in the Arctic both for individuals and species. Stems of willow can be centuries old and vegetatively reproducing clones can have their ages counted in millennia. Circum-polar examination of chlor

The indigenous North American Cranberry (Vaccinium macrocarpon), when cultivated in specially constructed cranberry bogs, is normally flooded in winter to prevent frost injury. This protection under ice can give rise to prolonged periods of anoxia, w

Examination of temperature variations over the past century for Europe and the Arctic from northern Norway to Siberia suggests that variations in the North Atlantic Oscillation are associated with an increase in oceanicity in certain maritime regions
