Redevelopment of Al-Gor Shoe Mill : Rochester, New Hampshire
As stated in the thesis project, "Rochester, New Hampshire is a small city of about 30,000 residents. It is located on the east border of New Hampshire, abutting Lebanon, Maine. Rochester is approximately 100 miles due north of Boston, Massachusetts. In years past, the driving forces of Rochester have included industries of shoe and leather production, agriculture, and services. Many of the commercial interests have moved to climates friendlier in temperature and labor. Others have simply folded....The primary goal of this project was to obtain development rights of the Al-Gor Shoe Mill in Rochester, New Hampshire. Secondary goals included utilizing the mill buildings and creating affordable housing and commercial space." (Library-derived description)Robblee, D. A. (1992).

Connecting life history stages of the Pink Shrimp from Dry Tortugas, Florida, USA [Poster abstract]
Variability in supply and cross-shelf transport of pink shrimp (Farfantepenaeus duorarum) postlarvae into western Florida Bay
The variability in the supply of pink shrimp (Farfantepenaeus duorarum) postlarvae and the transport mechanisms of planktonic stages were investigated with field data and simulations of transport. Postlarvae entering the nursery grounds of Florida Bay were collected for three consecutive years at channels that connect the Bay with the Gulf of Mexico, and in channels of the Middle Florida Keys that connect the southeastern margin of the Bay with the Atlantic Ocean. The influx of postlarvae in the Middle Florida Keys was low in magnitude and varied seasonally and among years. In contrast, the greater postlarval influx occurred at the northwestern border of the Bay, where there was a strong seasonal pattern with peaks in influx from July through September each year. Planktonic stages need to travel up to 150 km eastward between spawning grounds (northeast of Dry Tortugas) and nursery grounds (western Florida Bay) in about 30 days, the estimated time of planktonic development for this species. A Lagrangian trajectory model was developed to estimate the drift of planktonic stages across the SW Florida shelf. The model simulated the maximal distance traveled by planktonic stages under various assumptions of behavior. Simulation
results indicated that larvae traveling with the instantaneous current and exhibiting a diel behavior travel up to 65 km and 75% of the larvae travel only 30 km. However, the eastward distance traveled increased substantially when a larval response to tides was added to the behavioral variable (distance increased to 200 km and 85% of larvae traveled 150 km). The question is, when during larval development, and where on the shallow SW Florida shelf, does the tidal response become incorporated into the behavior of pink shrimp
Community Structure and Production in a Marsh on the Southern Branch of the Elizabeth River, Virginia
Four different plant communities occur on the Southern Branch of the Elizabeth River, Virginia, 1. Spartina alterniflora, 2. Distichlis spicata - Spartina patens - Juncus roemerianus, J. Baccharis halimifolia - Iva frutescens and 4. Spartina cynosuroides. The cordgrasses s. alterniflora and S. cynosuroides dominate the marsh.
Based-on standing crop estimates S. alterniflora produced 1218.6 grams dry wt/m2 and S.cynosuroides 1681.3 grams dry wt/m2, which is much higher than generally assumed for Virginia marshes. Evidence for the presence of two crops of S. alterniflora on the marsh during the growing season is-presented.
Two animal associations, composed of typically marsh associated invertebrates, were defined. The low marsh association was dominated by Uca minax, Modiolus demissus, Sesarma reticulatum, Uca pugnax, Littorina irrorata and Polymesoda caroliniana, and the high marsh by Uca minax. Sesarma cinereum and Melampus bidentatus. Uca minax was the major dominant throughout the marsh.
Frequency of tidal inundation was thought to be the principal factor delineating plant and animal communities. This factor and salinity appeared to be the primary regulator of the density of marsh invertebrates.
Comment is made on communities present in the adjacent river and the influence of the marsh on these waters
