Extreme Measures Imagining what the earth might look like in the year 802701 seems absurd. The date is unfathomably distant: some 160 times longer than the roughly 5, 000 years that comprise all of recorded human history. What could we hope to know about such a remote moment in time? What methods could we use to speculate so far into the future?
Aug 18, 2009 · In Chapter 1, I proposed a definition of extreme organisms by reference to the life boxes of organisms: the range of physical conditions under which they exist (the non-biological features of their ecological niche). I also proposed that we could recognise two groups of extreme organisms.

Organismal distribution limits and responses to climate change depend on how physiological performance varies as the environment shifts between optimal and extreme conditions.
Outstanding examples are evolutionary diversification following mass extinctions caused by extreme volcanism or asteroid impact. The evolution of organisms in contemporary time is typically viewed as a gradual and incremental process that results from genetic change, environmental perturbation or both.
These organisms have an extreme biology, which involves many aspects of their physiology, ecology and evolution. In this captivating account, the reader is taken on a tour of extreme environments, and shown the remarkable abilities of organisms to survive a range of extreme conditions, such as high and low temperatures and desiccation.
May 8, 2017 · Here, we assess the extent to which extreme population responses are individualistic (i.e. whether there is an agreement among species about which years are ‘extreme’), and evaluate whether extreme population responses are important determinants of species' long-term population trends.
