Modeling Implantable Passive Mechanisms for Modifying the Transmission of Forces and Movements Between Muscle and Tendons

Creator:: Homayouni, Taymaz, Underwood, Kelsey N., Beyer, Kamin C., Martin, Elon R., Allan, Christopher H., and Balasubramanian, Ravi
Abstract:: This paper explores the development of biomechanical models for evaluating a new class of passive mechanical implants for orthopedic surgery. The proposed implants take the form of passive engineered mechanisms, and will be used to improve the functional attachment of muscles to tendons and bone by modifying the transmission of...

Evaluating spatial patterns of drought-induced tree mortality in a coastal California pine forest

Creator:: Baguskas, Sara A., Peterson, Seth H., Bookhagen, Bodo, and Still, Christopher J.
Abstract:: In a coastal, fog-influenced forest on Santa Cruz Island in southern California, we observed mortality of Bishop pine (Pinus muricata D.Don) trees following a brief (2 year), yet intense, drought. While anecdotal evidence indicates that drought-induced Bishop pine mortality has occurred in the past in the stand we studied, this...

Spatial Ecological Processes and Local Factors Predict the Distribution and Abundance of Spawning by Steelhead (Oncorhynchus mykiss) across a Complex Riverscape

Creator:: Falke, Jeffrey A., Dunham, Jason B., Jordan, Christopher E., McNyset, Kristina M., and Reeves, Gordon H.
Abstract:: Processes that influence habitat selection in landscapes involve the interaction of habitat composition and configuration and are particularly important for species with complex life cycles. We assessed the relative influence of landscape spatial processes and local habitat characteristics on patterns in the distribution and abundance of spawning steelhead (Oncorhynchus mykiss),...

The Plant Actin Cytoskeleton Responds to Signals from Microbe-Associated Molecular Patterns

Creator:: Henty-Ridilla, Jessica L., Shimono, Masaki, Li, Jiejie, Chang, Jeff H., Day, Brad, and Staiger, Christopher J.
Abstract:: Plants are constantly exposed to a large and diverse array of microbes; however, most plants are immune to the majority of potential invaders and susceptible to only a small subset of pathogens. The cytoskeleton comprises a dynamic intracellular framework that responds rapidly to biotic stresses and supports numerous fundamental cellular...

Switching Hemispheres: A New Migration Strategy for the Disjunct Argentinean Breeding Population of Barn Swallow (Hirundo rustica)

Creator:: Garcia-Perez, Belen, Hobson, Keith A., Powell, Rebecca L., Still, Christopher J., and Huber, Gernot H.
Abstract:: Background: Barn Swallows (Hirundo rustica) breed almost exclusively in the Northern Hemisphere. However, since the early 1980's, a small disjunct breeding population has become established in eastern Argentina, presumably by birds previously derived from those breeding in North America. Currently, it is unknown where these individuals go following breeding and...

Air-Sea Interactions from Westerly Wind Bursts During the November 2011 MJO in the Indian Ocean

Creator:: Moum, James N., de Szoeke, Simon P., Smyth, William D., Edson, James B., DeWitt, H. Langley, Moulin, Aurélie J., Thompson, Elizabeth J., Zappa, Christopher J., Rutledge, Steven A., Johnson, Richard H., and Fairall, Christopher W.
Abstract:: The life cycles of three Madden–Julian oscillation (MJO) events were observed over the Indian Ocean as part of the Dynamics of the MJO (DYNAMO) experiment. During November 2011 near 0°, 80°E, the site of the research vessel Roger Revelle, the authors observed intense multiscale interactions within an MJO convective envelope,...

Leaf processing behaviour in Atta leafcutter ants: 90% of leaf cutting takes place inside the nest, and ants select pieces that require less cutting

Creator:: Garrett, Ryan W., Carlson, Katherine A., Goggans, Matthew Scott, Nesson, Michael H., Shepard, Christopher A., and Schofield, Robert M. S.
Abstract:: Leafcutter ants cut trimmings from plants, carry them to their underground nests and cut them into smaller pieces before inoculating them with a fungus that serves as a primary food source for the colony. Cutting is energetically costly, so the amount of cutting is important in understanding foraging energetics. Estimates...

Micromechanics of cellularized biopolymer networks

Creator:: Jones, Christopher A. R., Cibula, Matthew, Feng, Jingchen, Krnacik, Emma A., McIntyre, David H., Levine, Herbert, and Sun, Bo
Abstract:: Collagen gels are widely used in experiments on cell mechanics because they mimic the extracellular matrix in physiological conditions. Collagen gels are often characterized by their bulk rheology; however, variations in the collagen fiber microstructure and cell adhesion forces cause the mechanical properties to be inhomogeneous at the cellular scale....

Reduction in carbon uptake during turn of the century drought in western North America

Creator:: Schwalm, Christopher R., Williams, Christopher A., Schaefer, Kevin, Baldocchi, Dennis D., Black, T. Andrew, Goldstein, Allen H., Law, Beverly E., Oechel, Walter C., Paw U, Kyaw Tha, and Scott, Russel L.
Abstract:: Fossil fuel emissions aside, temperate North America is a net sink of carbon dioxide at present¹⁻³. Year-to-year variations in this carbon sink are linked to variations in hydroclimate that affect net ecosystem productivity³,⁴. The severity and incidence of climatic extremes, including drought, have increased as a result of climate warming⁵⁻⁸....

Systematic Temporal Patterns in the Relationship Between Housing Development and Forest Bird Biodiversity

Creator:: Pidgeon, Anna M., Flather, Curtis H., Radeloff, Volker C., Lepczyk, Christopher A., Keuler, Nicholas S., Wood, Eric M., Stewart, Susan I., and Hammer, Roger B.
Abstract:: As people encroach increasingly on natural areas, one question is how this affects avian biodiversity. The answer to this is partly scale-dependent. At broad scales, human populations and biodiversity concentrate in the same areas and are positively associated, but at local scales people and biodiversity are negatively associated with biodiversity....
