Extinction risk from climate change

TLDR
Estimates of extinction risks for sample regions that cover some 20% of the Earth's terrestrial surface show the importance of rapid implementation of technologies to decrease greenhouse gas emissions and strategies for carbon sequestration.
Abstract
Climate change over the past approximately 30 years has produced numerous shifts in the distributions and abundances of species and has been implicated in one species-level extinction. Using projections of species' distributions for future climate scenarios, we assess extinction risks for sample regions that cover some 20% of the Earth's terrestrial surface. Exploring three approaches in which the estimated probability of extinction shows a power-law relationship with geographical range size, we predict, on the basis of mid-range climate-warming scenarios for 2050, that 15-37% of species in our sample of regions and taxa will be 'committed to extinction'. When the average of the three methods and two dispersal scenarios is taken, minimal climate-warming scenarios produce lower projections of species committed to extinction ( approximately 18%) than mid-range ( approximately 24%) and maximum-change ( approximately 35%) scenarios. These estimates show the importance of rapid implementation of technologies to decrease greenhouse gas emissions and strategies for carbon sequestration.

Maximum entropy modeling of species geographic distributions

TL;DR: In this paper, the use of the maximum entropy method (Maxent) for modeling species geographic distributions with presence-only data was introduced, which is a general-purpose machine learning method with a simple and precise mathematical formulation.

Modeling of species distributions with Maxent: new extensions and a comprehensive evaluation

TL;DR: This paper presents a tuning method that uses presence-only data for parameter tuning, and introduces several concepts that improve the predictive accuracy and running time of Maxent and describes a new logistic output format that gives an estimate of probability of presence.

Rapid Range Shifts of Species Associated with High Levels of Climate Warming

TL;DR: A meta-analysis shows that species are shifting their distributions in response to climate change at an accelerating rate, and that the range shift of each species depends on multiple internal species traits and external drivers of change.

Deforestation Predicts the Number of Threatened Birds in Insular Southeast Asia

TL;DR: In this article, the authors mapped the percentage of deforestation on the islands of the Philippines and Indonesia and counted the num- ber of bird species found only on these islands, and then used the species-area relationship to calculate the number of species predicted to become globally extinct following deforestation.

Potential changes in the distributions of latitudinally restricted Australian butterfly species in response to climate change

TL;DR: This paper assessed potential changes in the distributions of Australian butterfly species in response to global warming and found that the majority of these species had fairly wide climatic ranges in comparison to other taxa, with only 8% of butterfly species having a mean annual temperature range spanning less than 3°C.

The impact of temperature on the northern distribution limits of the introduced species Fallopia japonica and Impatiens glandulifera in north-west Europe

TL;DR: Testing the predictions of sensitivity on two matrix population growth models, for annual and perennial vegetation, found the northern distri- bution limit of F. japonica was found to be controlled by two climatic variables-the length of the growing season, measured in day-degrees, and the minimum temperature- while for I. glandulifera only the length ofthe growing season was critical.
