T he inSpace project is an interdisciplinary collaboration between the Georgia Institute of Technology and Steelcase, bringing together expertise in humancomputer interaction, ubiquitous computing infrastructure, industrial design, furniture and interior design, and architecture. InSpace has two central goals. The first is to understand how guiding principles in the design of the physical world...
We examine the logic of designing nature reserves to understand better how to integrate the concepts of representativeness and persistence. Simple models of viability are used to evaluate how the expected number of species in the reserve system changes with variation in the risk of extinction among species, their rate of occurrence, and the distribution of species. The optimal size of individua...
Benjamin S. Halpern* and Robert R. Warner Department of Ecology, Evolution, and Marine Biology, University of California, Santa Barbara, CA, 93106, U.S.A. *Correspondence: E-mail: [email protected] Abstract Marine reserves are becoming a popular tool for marine conservation and resource management worldwide. In the past, reserves have been created with little understanding of how they ac...
CFTR is a transmembrane protein that reaches the cell surface via the conventional Golgi mediated secretion pathway. Interestingly, ER-to-Golgi blockade or ER stress induces alternative GRASP-mediated, Golgi-bypassing unconventional trafficking of wild-type CFTR and the disease-causing ΔF508-CFTR, which has folding and trafficking defects. Here, we show that Sec16A, the key regulator of convent...
Marine reserves are an effective tool for protecting biodiversity locally, with potential economic benefits including enhancement of local fisheries, increased tourism, and maintenance of ecosystem services. However, fishing communities often fear short-term income losses associated with closures, and thus may oppose marine reserves. Here we review empirical data and develop bioeconomic models ...
Active participation of demand-side resources in power system control tasks, i.e., demand response, is expected to facilitate the integration of renewable energy sources in the grid. In this paper, we present a novel hierarchical control scheme to enable provision of frequency control reserves by a pool of office buildings managed by an aggregator. The reserves are provided by controlling the c...
No-take marine reserves show great promise as conservation tools, yet the integration of reserves into assessment models for data-limited fisheries management is just emerging. We develop a framework for integrating marine reserves into two data-limited assessment models: spawning potential ratio (SPR) and yield per recruit (YPR). We use Monte Carlo simulation to test the applicability of the f...
Marine reserves are widely used throughout the world to prevent overfishing and conserve biodiversity, but uncertainties remain about their optimal design. The effects of marine reserves are heterogeneous. Despite theoretical findings, empirical studies have previously found no effect of size on the effectiveness of marine reserves in protecting commercial fish stocks. Using 58 datasets from 19...
We have used an end-to-end ecosystem model to explore responses over 30 years to coastal no-take reserves covering up to 6% of the fifty thousand square kilometres of continental shelf and slope off the coast of New South Wales (Australia). The model is based on the Atlantis framework, which includes a deterministic, spatially resolved three-dimensional biophysical model that tracks nutrient fl...
Models for marine reserve design have been developed primarily with 'reef fish' life histories in mind: sedentary adults in patches connected by larval dispersal. However, many fished species undertake ontogenetic migrations, such as from nursery grounds to adult spawning habitats, and current theory does not fully address the range of reserve options posed by that situation. I modelled a gener...
