The problem of extinction in the sea has been recognized
only recently by the scientific community (Roberts and
Hawkins 1999). For the last decade, the American Fisheries
Society (AFS) has pursued an initiative to identify marine
fish stocks that may be at risk of extinction in North America
(Musick 1998;...
Much of the focus of digital collections has been and continues to be on rare and unique materials,
including monographs. A monograph may be made even rarer and more valuable by virtue of hand
written marginalia. Using technology to enhance scans of unique books and make previously
unreadable marginalia readable...
The article discusses how to bring the educational benefits that come from analyzing and interpreting physical materials to a bigger class environment and whether these benefits are worth the costs. It notes the growth of literature on instruction in special collections environments and the creative instructional methods presented by its...
Deciding which textbook to assign to students is often a very difficult decision. A textbook should offer more than just a synthesis of information, it should inspire curiosity, cause one to reflect, and provide a framework for making decisions. Most reviews reflect a single opinion, sometimes based on personal preferences....
In this paper, we describe a fusion approach to finding opinionated blog postings. Our approach to opinion blog retrieval consisted of first applying traditional IR methods to retrieve on-topic blogs and then boosting the ranks of opinionated blogs based on combined opinion scores generated by multiple assessment methods. Our opinion...
This paper supersedes and significantly revises my compilation of 1992. The focus remains on live birds seen on or from land, but special codes are now given for records of species only reported beached or at sea.
Additionally, confirmation codes are now listed for records of some rare species and...
I explore the proposition that evolutionary biology is
currently in the midst of its greatest period of synthesis. This period,
which I call the Ongoing Synthesis, began in 1963 and continues at
the present time. I use analysis of citations, conduct, and content to
compare the Ongoing Synthesis to widely...
We used a combination of seabird data (both fishery-dependent and fishery-independent) and fishing-effort data to evaluate the relative fisheries risk of five west coast groundfish fisheries and oneshrimp fishery to black-footed (Phoebastria nigripes), short-tailed (P. albatrus) and Laysan albatrosses(P. immutabilis). To assess risk, an overlap index was derived as the...
Terrestrial ecosystem-atmosphere exchange of carbon, water vapor, and energy has been measured for over a decade at many sites globally. To minimize measurement and analysis errors, quality assurance data have been collected over short periods along-side tower instruments at AmeriFlux research sites. Theoretical and empirical error and uncertainty values have...
Population dynamics of coral reef fishes and spiny lobster appear to be determined by variable recruitment interacting with post-settlement processes, particularly predation. The risk of predation may be modified by the scaling between prey and shelter size, which enhances the protective capacity of a reef. We experimentally tested these predictions...
