Scholarcy highlights

  • Niche; Species distributions; Community composition; Extinction; Adaptation; Demography; Climate envelope models; Uncertainty; Forecasting; Prediction; Conservation; Species translocations
  • The body of knowledge about how the world works, must be re-evaluated before being accepted or rejected. It is through such judgment that scientists hone scientific knowledge. This knowledge is always abounded at the edges by uncertainty
  • 15-37% of terrestrial species may be ‘committed to extinction’ by 2050
  • This balance is upset during mass extinctions: the loss of more than three-quarters of species in a geologically short interval
  • Uncertainty in climate projections grows exponentially when downscaling from global to seasonal patterns. This discrepancy generates two main uncertainty issues when predicting species responses to climate change: species respond to local climate but it will require substantial advances in physical science to model local climate with certainty; and species performance is regulated by multiple factors, and the control exerted by each factor varies with environment
  • It is clear that we will be powerless to assess and predict ecological responses to climate change if we focus only on correlations between species distributions and environmental factors
