Landscapes, space and equilibrium: shifting viewpoints
The classical view of ecological systems has been one that assumes a state of equilibrium and stability; this is encapsulated in the ‘balance of nature’ paradigm. Over the last 30 years ecologists and biogeographers have rejected the view that ecological systems are inherently stable or at some sort of equilibrium. Instead a nonequilibrium view, emphasizing the role of chance events such as dis...
متن کاملDeep Learning Design for Sustainable Innovation within Shifting Learning Landscapes
Changes in the underpinning technologies for TEL is occurring at a pace that we have never before experienced, and this is unlikely to slow down. This necessitates a broader and more profound understanding of design that needs to be more future-proof than relying on the latest or emerging technologies and yet embraces the collaborative, multimodal and ubiquitous nature of learning in 21C. In ad...
متن کاملShifting fitness landscapes in response to altered environments.
The role of adaptation in molecular evolution has been contentious for decades. Here, we shed light on the adaptive potential in Saccharomyces cerevisiae by presenting systematic fitness measurements for all possible point mutations in a region of Hsp90 under four environmental conditions. Under elevated salinity, we observe numerous beneficial mutations with growth advantages up to 7% relative...
متن کاملTropical amphibians in shifting thermal landscapes under land-use and climate change.
Land-cover and climate change are both expected to alter species distributions and contribute to future biodiversity loss. However, the combined effects of land-cover and climate change on assemblages, especially at the landscape scale, remain understudied. Lowland tropical amphibians may be particularly susceptible to changes in land cover and climate warming because many species have narrow t...
متن کاملForests as landscapes of social inequality: tropical forest cover and land distribution among shifting cultivators
Can social inequality be seen imprinted in a forest landscape? We studied the relationship between land holding, land use, and inequality in a peasant community in the Peruvian Amazon where farmers practice swidden-fallow cultivation. Longitudinal data on land holding, land use, and land cover were gathered through field-level surveys (n = 316) and household interviews (n = 51) in 1994/1995 and...
