Why Environmental Policy Nightmares Recur - Steven L. Yaffee (Conservation Biology, 1997)
Many natural resource and environmental policy issues evidence recurring choices, made with considerable effort, whose temporary solutions never seem to deal with the underlying problems. Drawing on examples from endangered species policy, I describe five behavioral tendencies of humans and human institutions that result in recurrent environmental policy problems, including poor long‐term direction, delays, impasses, and piecemeal solutions to crosscutting problems. These tendencies are short‐term rationality outcompeting long‐term rationality, competitive behavior driving out cooperative behavior, fragmentation of interests and values, fragmentation of responsibilities and authorities, and fragmentation of information and knowledge. By understanding these tendencies, it is possible to frame policy solutions to them. This paper identifies a set of necessary responses including finding ways to bind current decisionmakers to the future, promoting creativity and risk‐taking on the part of public resource management organizations, utilizing alternative dispute resolution mechanisms that foster cooperation, building political concurrence, utilizing coordinating mechanisms, instituting clear performance measures, and implementing ways to promote information flows between organizations.

Visualization of seawater flow around morphologically distinct forms of the giant kelp Macrocystis integrifolia from wave‐sheltered and exposed sites - Catriona L. Hurd; Craig L. Stevens; Bernard E. Lava; G. A. Lawrence; P. J. Harrison (Limnology and Oceanography, 1997)
Our objective was to determine whether blades of Macrocystis integrifolia from a wave‐sheltered site possess morphological features that “trip” velocity boundary layers (VBL) from laminar to turbulent in conditions of low water motion, compared to blades from a wave‐exposed site. The movement of seawater around morphologically distinct blades of M. integrifolia from wave‐sheltered and exposed sites was visualized in a recirculating flow tank in which seawater flow was initially laminar at velocities up to 8 cm s −1 . Turbulent VBLs were observed for both blade morphologies at free‐stream seawater velocities of 2 cm s −1 , and at a Reynolds numbers of between 10 2 and 10 4 , which is lower than that predicted from boundary layer theory. Flow around blades from a wave‐sheltered site was dominated by separation induced by large edge undulations. For the wave‐exposed morphology, the flow pattern was similar to that along a smooth, flat plate, but the observed thickness of the VBL was up to a factor of 2 greater than that predicted from laminar or turbulent boundary layer theory. There were no obvious differences in how structural features such as marginal spines and bulbs affected seawater flow around the different blade morphologies.

Methyl iodide production from marine phytoplankton cultures - Steven L. Manley; John L. de la Cuesta (Limnology and Oceanography, 1997)
Unialgal cultures of 15 species of marine phytoplankton were examined for the production of methyliodide (CH 3 I). CH 3 I production was quantified during log and stationary phases of phytoplankton growth in f/2 medium and compared to CH 3 I levels in control vessels. Significant increases in CH 3 I production were seen in five cultures. Phytoplankton CH 3 I production varied from a low of 10 −4 amol CH 3 I cell −1 d −1 to a high of 8 × 10 3 amol CH 3 I cell −1 d −1 . In three diatom cultures, the increase in total CH 3 I and cell‐based CH 3 I production rates were much higher during the log phase than during the stationary phase, even though the bacterial numbers continued to increase, supporting the premise of phytoplankton CH 3 I production. In two cultures, it was more difficult to distinguish between phytoplankton and bacterial production. Additional biotic and abiotic sources and sinks of CH 3 I were considered in the analysis, including bacterial consumption, chemical removal, and photochemical production. The only significant CH 3 I sink during the course of the experiment was its nucleophilic substitution with Cl − .
