Cold hardiness in relation to environmental factors and the underlying mechanisms that help plants in maintaining or reacquiring cold hardiness is discussed in this extensive review. Deacclimation and reacclimation of cold-hardy plants: current understanding and emerging concepts Kalberer et. al., Plant Science 2006, 171: 3-16
Underlying cellular mechanisms of how deacclimation and reacclimation capacities are affected by environmental changes is discussed in : Winter survival and deacclimation of perennials under warming climate: physiological perspectives. Pagter and Arora. Physiologia Plantarum 2013. 147: 75-87
Temperature is the most important ecological filter for range shift in species and populations. Under warmer climate, temperate vegetation may replace boreal vegetation. Read more about potential affects of global warming on vegetation of northern latitudes in Causes, impact and solutions to global warming: Chapter 1 by Taulavuori. 2013, pp 3-16
For voracious readers: Science special issue 2, August 2013 focuses on the current state of knowledge about the effects of climate change on natural systems, with particular emphasis on how knowledge of the past is helping us to understand potential biological impacts and improve predictive power. Natural systems in changing climate.
