Factors affecting the dynamics and regulation of coral-reef fish populations

Creator:: Webster, Michael Scott
Abstract:: Ecologists have long questioned why fluctuating populations tend to persist rather than go extinct. Populations that persist indefinitely are regulated by mechanisms that cause demographic density dependence, which works to bound fluctuation above zero. In a series of studies, I have sought to determine the processes and mechanisms that regulate...

An optical method for rapid examination of check development in decorative plywood panels

Creator:: Burnard, Michael David, Muszynski, Lech, Leavengood, Scott, and Ganio, Lisa
Abstract:: Common methods for assessment of surface checking in decorative plywood panels rely on manual handling and visual inspection of specimens, a laborious procedure practically limiting the number of materials and variables that may be considered within one project. In this study, a new automated optical method for detection and measurement...

TopCAT – Topographical Compartment Analysis Tool to analyze seacliff and beach change in GIS

Creator:: Olsen, Michael J., Young, Adam P., and Ashford, Scott A.
Abstract:: This paper discusses the development of a new GIS extension named the Topographic Compartment Analysis Tool (TopCAT), which compares sequential digital elevation models (DEMs) and provides a quantitative and statistical analysis of the alongshore topographical change. TopCAT was specifically designed for the morphological analysis of seacliffs and beaches but may...

Unconditioned Response to a Naturally Aversive Stimulus is Associated with Sensitized Defensive Responding and Self-Reported Fearful Traits in a PTSD Sample

Creator:: Lewis, Michael W., Bradford, Daniel E., Rauch, Scott L., and Rosso, Isabelle M.
Abstract:: Unconditioned responding (UCR) to a naturally aversive stimulus is associated with defensive responding to a conditioned threat cue (CS+) and a conditioned safety cue (CS-) in trauma-exposed individuals during fear acquisition. However, the relationships of UCR with defensive responding during extinction training, posttraumatic stress disorder (PTSD) symptom severity, and fearful...

Creator:: Stoklosa, Jakub, Daly, Christopher, Foster, Scott D., Ashcroft, Michael B., and Warton, David I.
Abstract:: 1. Spatial climate variables are routinely used in species distribution models (SDMs) without accounting for the fact that they have been predicted with uncertainty, which can lead to biased estimates, erroneous inference and poor performances when predicting to new settings – for example under climate change scenarios. 2. We show...

Cryptolepiota, a new sequestrate genus in the Agaricaceae with evidence for adaptive radiation in western North America

Creator:: Kropp, Bradley R., Albee-Scott, Steve, Castellano, Michael A., and Trappe, James M.
Abstract:: Phylogenetic analyses based on nLSU and ITS sequence data indicate that the sequestrate genus Gigasperma is polyphyletic. Gigasperma cryptica, which is known only from New Zealand, has affinities with the Cortinariaceae whereas G. americanum and two additional undescribed taxa from western North America are derived from Lepiota within the Agaricaceae....

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...

Spectral particulate attenuation and particle size distribution in the bottom boundary layer of a continental shelf

Creator:: Boss, Emmanuel, Pegau, W. Scott, Gardner, Wilford D., Zaneveld, J. Ronald, Barnard, Andrew H., Twardowski, Michael S., Chang, G. C., and Dickey, T. D.
Abstract:: Spectral attenuation and absorption coefficients of particulate matter and collocated hydrographic measurements were obtained in the Mid-Atlantic Bight during the fall of 1996 and the spring of 1997 as part of the Coastal Mixing and Optics experiment. Within the bottom boundary layer (BBL) the magnitude of the beam attenuation decreased...
