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.read more

Modelling greenhouse gas emissions for municipal solid waste management strategies in Ottawa, Ontario, Canada
TL;DR: In this article, a modelling exercise was performed to determine greenhouse gas emissions from the waste sector using the waste disposal, recycling, and composting data from Ottawa, Ontario, Canada for the year 2003, as well as the results of an audit of residential units performed in the same year.

Lessons Learned While Integrating Habitat, Dispersal, Disturbance, and Life-History Traits into Species Habitat Models Under Climate Change
TL;DR: In this article, the authors present an approach to modeling potential climate-driven changes in habitat for tree and bird species in the eastern United States using an empirical-statistical modeling approach, using random forests with species abundance data from national inventories combined with soil, climate, and landscape variables.

Coping with the cold: predictors of survival in wild Barbary macaques, Macaca sylvanus
TL;DR: These findings support the view that sociality is directly related to an individual's fitness, and that factors promoting the establishment and maintenance of social relationships are favoured by natural selection.

TL;DR: Analysis of long-term, community-wide monitoring data from two sites in high-arctic Greenland and how a collapse in collared lemming cyclicity affects the population dynamics of the predator guild shows population extinctions and community restructuring of this arctic endemic predator guild are likely if the lemsing dynamics are maintained at the current non-cyclic, low-density state.
