Artificial wetlands to augment use by estuarine birds Artificial wetlands to augment use by estuarine birds
The value of natural wetlands to bird populations is well-recognized, and declines in waterfowl numbers are often attributed to losses in wetland area. if the destruction of wetland reduces bird populations, then adding wetland habitats might improve the situation. This idea was tested in Tijuana Estuary in the late 1980s.

Developing a criterion for delisting the southern sea otter under the U.S. Endangered Species Act Developing a criterion for delisting the southern sea otter under the U.S. Endangered Species Act
Recent surveys of recovery plans indicate that criteria, such as population sizes, for delisting species from the U.S. Endangered Species Act (ESA) are often unrealistically low by scientific standards. We describe the delisting criterion for the threatened southern sea otter (Enhydra lutris nereis) developed by the Southern Sea Otter Recovery Team. A major oil spill is the most serious...

A new assay for quantifying brown algal phlorotannins and comparisons to previous methods A new assay for quantifying brown algal phlorotannins and comparisons to previous methods
Quantitative measurement of phlorotannins (polyphenolics) in brown algae (Phaeophyta) by colorimetric assays can be confounded because: (1) most such assays also react to nonphlorotannin substances (interferences) and (2) the appropriate reference compound for such assays is not always clear, although phloroglucinol is typically used. We developed a new assay in which 2,4...
