Natural disturbances and human activities can alter the benthic composition of coral reefs and other marine ecosystems. Reef fishes that associate with particular structures on the sea floor, such as coral heads, may be vulnerable to perturbations of those habitats. The spread of a newly discovered crustose alga (Ramicrusta sp.)...

In his Nick Adams stories, Ernest Hemingway traces the life of a single man as he moves from boyhood to adolescence to adulthood to fatherhood. From the beginning of Nick Adams life, it is clear that he does not fit into the role of the traditional hero. In addition, Nick...
Cinder cones are useful geomorphic features for geological analysis because they generally have known initial states and follow a similar pattern of degradation as they are exposed to erosive processes. This is largely because cinder cones are produced by monogenetic eruptions. Characterizing large cinder cone fields in terms of age...
Provides information about complexity of watersheds. Outlines ways to form partnerships, to develop strategies for enhancing watershed resources, and to implement enhancement projects.

In late 18th century Britain, Adam Smith was the most influential thinker and writer to offer policy advice on fishery subsidies. In The Wealth of Nations, Smith scoffed at the so-called white herring bounties. He used data from 1771-1781 to argue that the bounties had raised the price of locally-caught...
Magnetotellurics is used in two geologic settings on scales ranging from 1000-km tectonic structures to local features hundreds of meters wide. These areas are the Midcontinent Rift System (MRS) and its related mantle plume in the northern Midwestern United States and Newberry Volcano in central Oregon.
The MRS study uses...
A simplified model of the combined particle convective and
radiative components of heat transfer between large-particle gas-fluidized
beds and immersed surfaces was developed. This analytical
model was based on the single particle formulation of Adams and Welty
[4,9], with the added assumptions of one-dimensional heat conduction
in the particle and...
Silicic caldera-forming eruptions are some of the largest and most destructive volcanic eruptions known, and present significant local and global hazards. The underlying processes within crustal magma plumbing systems that lead to the accumulation and eruption of large volumes of evolved magma remain enigmatic, yet there is broad consensus that...
Demanding task environments (e.g., supervising a remotely piloted aircraft) require performing tasks quickly and accurately; however, periods of low and high operator workload can decrease task performance. Intelligent modulation of the system’s demands and interaction modality in response to changes in operator workload state may increase performance by avoiding undesirable...
