Creator:: Lachenbruch, Barbara and McCulloh, Katherine A.
Abstract:: This review presents a framework for evaluating how cells, tissues, organs, and whole plants perform both hydraulic and mechanical functions. The morphological alterations that affect dual functionality are varied: individual cells can have altered morphology; tissues can have altered partitioning to functions or altered cell alignment; and organs and whole...

Creator:: Lagerquist, Barbara A. and Mate, Bruce R.
Abstract:: The Oregon coast has been identified as an area with great potential for production of electricity from wave and wind energy, and development of marine renewable energy facilities are being discussed for several locations along the Oregon coast. The potential impact of this development on eastern gray whales is largely...

Abstract:: People of all ages are intrigued by the ocean, its inhabitants, dynamics and future. Our knowledge grows, but we change the ocean as we use its resources thus creating environmental problems and management challenges. When this volume is published, the Gulf of Mexico will not have recovered from the Deepwater...

Creator:: Chaffin, Brian C., Gosnell, Hannah, and Cosens, Barbara A.
Abstract:: Adaptive governance is an emergent form of environmental governance that is increasingly called upon by scholars and practitioners to coordinate resource management regimes in the face of the complexity and uncertainty associated with rapid environmental change. Although the term “adaptive governance” is not exclusively applied to the governance of social-ecological...

Creator:: Wada, Sugae, Kennedy, James A., and Reed, Barbara M.
Abstract:: Rubus seed has a deep double dormancy that restricts germination due to seed coat structure and chemical composition. Improved germination of diverse Rubus species required for breeding improved blackberry and raspberry cultivars is partly dependent on the seed coat structure. This study evaluated the seed coat structure of three species...

Abstract:: Wildlife epidemiological outcomes can depend strongly on the composition of an ecological community, particularly when multiple host species are affected by the same pathogen. However, the relationship between host species richness and disease risk can vary with community context and with the degree of spillover transmission that occurs among co-occurring...

Abstract:: • Premise of the study: The pathway of radial water movement in tree stems presents an unknown with respect to whole-tree hydraulics. Radial profi les have shown substantial axial sap fl ow in deeper layers of sapwood (that may lack direct connection to transpiring leaves), which suggests the existence of...

Abstract:: Ambient ultraviolet-B radiation can harm amphibian eggs, larvae and adults. However, some amphibians avoid UV-B radiation when given the opportunity. The strawberry poison dart frog, Oophaga pumilio, is diurnal and males vocalize throughout the day in light gaps under forest canopies that expose them to solar radiation. Previous studies have...

Abstract:: Given the fundamental importance of xylem safety and efficiency for plant survival and fitness, it is not surprising that these are among the most commonly studied features of hydraulic architecture. However, much remains to be learned about the nature and universality of conflicts between hydraulic safety and efficiency. Although selection...

Abstract:: Premise of the study: The Pacific Northwest of North America experiences relatively mild winters and dry summers. For the tall coniferous trees that grow in this region, we predicted that loss in the hydraulic conductivity of uppermost branches would be avoided because of difficulty reversing accumulated emboli in xylem that...
