Physical aspects of Hurricane Hugo in Puerto Rico
On 18 September 1989 the western part ofHurricane Hugo crossed eastern Puerto Rico and the Luquillo Experimental Forest (LEF). Storm-facing slopes on the northeastern part of the island that were within 15 km of the eye and received greater than 200 mm of rain were most affected by the storm. In the LEF and nearby area, recurrence intervals associated with Hurricane Hugo were 50 yr for wind veloci

Decreased survival of rainbow trout exposed to no. 2 fuel oil caused by sublethal preexposure
Rainbow trout (Oncorhynchus mykiss) were exposed for 21 d to sublethal levels of No. 2 fuel oil (2FO). The four exposure concentrations ranged from 12 to 100 mg/L 2FO dispersed in water and resulted in 0 to 12% mortality. Following this exposure period (preexposure) the ability of preexposed trout to survive exposure to acutely lethal levels of 2FO was observed. Preexposure to either 50 or 100 mg/

Simulation of the effects of proposed tide gates on circulation, flushing, and water quality in residential canals, Cape Coral, Florida
Decades of dredging and filling of Florida's low-lying coastal wetlands have produced thousands of miles of residential tidal canals and adjacent waterfront property. Typically, these canals are poorly flushed, and over time, accumulated organic-rich bottom materials, contribute to an increasingly severe degraded water quality. One-dimensional hydrodynamic and constituent-transport models were app

Additions to the ichthyofauna of the Bahama Islands, with comments on endemic species
Literature records or other documentation are given for 57 species of shorefishes added to the Bahaman ichthyofauna since publication of Fishes of the Bahamas; included are 32 new species described or discovered since 1967. Known distribution is specified for each species, including extralimital ranges of non-endemics. Fourteen species are listed as known only from the Bahamas although some likely
