    Description: A total of 213 holothurians, representing 16 species, was collected during Project Hourglass, a28-month systematic survey of ten stations along two transects (6-73 m) off central western Florida.This material, supplemented with 8 1 additional Gulf of Mexico specimens supplied by the FloridaDepartment of Natural Resources, brings the total number of species reported in this paper to 20. Ofthese species, 19 have previously been reported from the Gulf of Mexico. One, Allothyone mexicana,can be considered endemic to the Gulf of Mexico, and another, Thyone crassidisca, was recentlydescribed from material including Hourglass specimens. Systematic accounts, pertinent ecologicaldata and line drawings of taxonomically important skeletal elements are included for each species.Keys to all 60 holothurian species known from the Gulf of Mexico are provided. Range extensionsfor several species are noted. (Document contains 79 pages.)

    Description: We evaluated the use of strip-transect survey methods for manatees through aseries of replicate aerial surveys in the Banana River, Brevard County, Florida, duringsummer 1993 and summer 1994. Transect methods sample a representative portion ofthe total study area, thus allowing for statistical extrapolation to the total area. Otheradvantages of transect methods are less flight time and less cost than total coverage, easeof navigation, and reduced likelihood of double-counting.Our objectives were: (1) to identify visibility biases associated with the transectsurvey method and to adjust the counts accordingly; (2) to derive a population estimatewith known variance for the Banana River during summer; and (3) to evaluate thepotential value of this survey method for monitoring trends in manatee population sizeover time.

    Description: The following discussion presents information on human-made reefs and their role--as one tool of many--in the management of both fisheries and habitat. Principal subjects covered in this paper include a definition of marine habitat improvement and determination of its attainment, the present applications of reef construction technology to environmental situations both generally and in three case-studies, and suggested desirable attributes for incorporation into future use of this technology. (PDF has 11 pages.)
    Description: Authors’ note: This document was the basis for a keynote presentation at the 2004 World Fisheries Congress, in a session on Marine Fisheries Habitat Improvement. Several of the slides shown there are included here, without captions.
