Consensus is growing that agriculture is vulnerable to climate change and adaptation responses are necessary to minimize impacts. Nonetheless, the diversity of potential impacts, agro-ecological contexts and regional capacity for change make understanding adaptation behaviors challenging and ensure that climate change adaptation will not be the same across all contexts. Considering this heterog...
Climate-related changes in glacierized watersheds are widely documented, stimulating adaptive responses among the 370 million people living in glacier-influenced watersheds as well as aquatic and riparian ecosystems. The situation denotes important interdependencies between science, society, and ecosystems, yet integrative approaches to the study of adaptation to such changes remain scarce in b...
Local adaptation is often obvious when gene flow is impeded, such as observed at large spatial scales and across strong ecological contrasts. However, it becomes less certain at small scales such as between adjacent populations or across weak ecological contrasts, when gene flow is strong. While studies on genomic adaptation tend to focus on the former, less is known about the genomic targets o...
Human societies are remarkably variable in terms of their size, complexity, social structure, marriage systems and norms. This diversity has sometimes been raised as an obstacle to taking an evolutionary approach to human behaviour. However, a substantial proportion of the variation between human societies might represent local adaptation to ecological conditions and would thus be very much ame...
This paper compares systematically the two theoretical models of adaptation, ecological and evolutionary. Using notions from innovation, learning, and balanced change, the two models are contrasted in the context of 73 European, Japanese, and U.S. industrial robotics firms that introduced new robotics products in 1984-1997. A hybrid of ecological and evolutionary views is found to predict innov...
