The breadth of a species' climatic niche is an important ecological trait that allows adaptation to climate change, but human activities often reduce realised by impacting species distributions. Some life-history traits, such as dispersal ability and reproductive speed, allow cope with both impact change. But how do these traits interact pressure determine change? Here we investigate the patter...

Species ranges are mediated by physiology, environmental factors, and competition with other organisms. The allopatric distribution of five species of northern Californian pocket gophers (Thomomys spp.) is hypothesized to result from competitive exclusion. The five species in this environmentally heterogeneous region separate into two subgenera, Thomomys or Megascapheus, which have divergent di...

Expansive soils can be found in many parts of the world particularly in arid and semi-arid regions. These soilspose a significant hazard to civil engineering structures due to its high swelling and shrinkage potential. This paperpresents the results of an experimental program developed to investigate the effect of cyclic drying and wetting on theswelling potential of expansive soils with variou...
