Climate Risk Polycentricity And The Iad Framework, Troy D. Abel, Mark Stephan, Dorothy Daley Jan 2014

Climate Risk Polycentricity And The Iad Framework, Troy D. Abel, Mark Stephan, Dorothy Daley

Troy D. Abel

Climate change is commonly cast as a significant governance challenge demanding national and international actions. Subsequently, political science research tends to focus on the policy and politics of nation-states, their domestic institutions, and/or their interplay in international venues. However, thousands of industrial facilities and hundreds of subnational US governments are active in American climate risk governance. Therefore, we argue that more research should attend to climate governance’s subnational policy and politics, their promise, and their performance. In the vacuum of national policies to mitigate and adapt to climate-change, subnational arrangements offer an ideal opportunity to study not only the spontaneity …

Thicker Host Tissues Moderate Light Stress In A Cnidarian Endosymbiont, James L. Dimond, Benjamin J. Holzman, Brian L. Bingham Jul 2012

Thicker Host Tissues Moderate Light Stress In A Cnidarian Endosymbiont, James L. Dimond, Benjamin J. Holzman, Brian L. Bingham

Brian L. Bingham

The susceptibility of algal-cnidarian holobionts to environmental stress is dependent on attributes of both host and symbiont, but the role of the host is often unclear. We examined the influence of the host on symbiont light stress, comparing the photophysiology of the chlorophyte symbiont Elliptochloris marina in two species of sea anemones in the genus Anthopleura. After 3 months of acclimation in outdoor tanks, polyp photoprotective contraction behavior was similar between the two host species, but photochemical efficiency was 1.5 times higher in A. xanthogrammica than in A. elegantissima. Maximum relative electron transport rates, derived from rapid light curves, were …


Recent Unprecedented Tree-Ring Growth In Bristlecone Pine At The Highest Elevations And Possible Causes, Matthew W. Salzer, Malcolm K. Hughes, Andrew G. Bunn, Kurt F. Kipfmueller Dec 2009

Recent Unprecedented Tree-Ring Growth In Bristlecone Pine At The Highest Elevations And Possible Causes, Matthew W. Salzer, Malcolm K. Hughes, Andrew G. Bunn, Kurt F. Kipfmueller

Andrew G. Bunn

Great Basin bristlecone pine (Pinus longaeva) at 3 sites in western North America near the upper elevation limit of tree growth showed ring growth in the second half of the 20th century that was greater than during any other 50-year period in the last 3,700 years. The accelerated growth is suggestive of an environmental change unprecedented in millennia. The high growth is not overestimated because of standardization techniques, and it is unlikely that it is a result of a change in tree growth form or that it is predominantly caused by CO2 fertilization. The growth surge has occurred only in …
