“…They predicted that elements {a) and {d} would predominate in the region. Humm (1969) characterized the region as a long transition zone between a Caribbean centered, tropical flora and a North Atlanticcentred, cool/cold water flora. He said that elements of each flora extended different distances into or across the region, but recognized no species with a distribution centred in the region.…”

“…Study of the seaweeds ° * of the mid-Atlantic coast of the United States has resulted in an increasing number of papers on seaweed biogeography in the region during the course of this century (Hoyt, 1920;Stephenson & Stephenson, 1952;Humm, 1969;van den Hoek, 1975;Schneider, 1976;Kapraun, 1980;Searles & Schneider, 1980).

ABSTRACT:The northern boundary of the warm temperate region of the mid-Atlantic coast of the United States is set at Cape Hatteras; the southern boundary lies at Cape Canaveral. There is some spillover of cool temperate species south of Cape Hatteras into North Carolina and spillover of warm temperate species south of Cape Canaveral toward Palm Beach. Elements of the warm temperate flora also extend into the northern Gulf of Mexico, but precise limits to the flora cannot be drawn there. Thirty-one species are endemic to the warm temperate flora. The inshore waters of North Carolina include approximately equal numbers of species with northern and southern centres of distribution; the species of the offshore waters have predominantly southern affinities, but also include most of the endemic species. Seasonal changes in the shallow water flora of North Carolina reflect eurythermal cool temperate and tropical elements in winter and summer respectively and a year-round warm temperate element. These groupings have been verified by experimental studies in which light and temperature were varied. The deep water flora is a summer flora dominated by perennial species. The inshore, eurythermal cool temperate and tropical species have a variety of cryptic stages by which they persist throughout the year.

“…TampaBay is considered by some authors (Hedgpeth 1953, Rehder 1954, Earle 1969, Humm 1969 to be the boundary between the warm-temperate Carolinean province and the tropical Antillean province for marine organisms along the Gulf coast of Florida. The hermit crab fauna ofthe TampaBay area reflects the transition between these 2 provinces.…”

Fourteen species of hermit crabs, belonging to 5 genera, were identified from 35 stations in Tampa Bay and adjacent continental shelf waters. Ninety-two samples were taken from the intertidal zone to 15 m with a variety of gear including dip nets, trawls, dredges, and hand collections using SCUBA. Pagurus maclaughlinae, Pagurus longicarpus, and Pagurus pollicaris were distributed throughout the bay. These species were often sympatric, and were commonly found in seagrass beds, sandy substrates, and sand/mud substrates, respectively. Clibanarius vittatus, Pagurusgymnodactylus, and Pagurus stimpsoni inhabited the higher salinity waters of the bay entrance. Paguristes sp., Paguristes hummi, Pagurus impressus and Petrochirus diogenes were collected from the lower bay to offshore on hard substrates and sand. Paguristes puncticeps, Paguristes sericeus and Pagurus carolinensis were collected only offshore on hard substrates. The latter species is reported from the Gulf of Mexico for the first time. Isocheles wurdemanni appears to be restricted to high energy beaches. An illustrated key as well as information on distribution, reproductive biology, taxonomic problems, symbionts, and coloration are presented.

“…Species of the genus Fucus are generally cold water plants; their geographical distribution is widely controlled by temperature (Set&ell, 1920;Hut&ins, 1947;Scagel, 1963;Humm, 1969;Gessner, 1970). Some fucoids are able to extend into estuaries and salinity is a further deciding factor for their local distribution (e.g.…”

Combined effects of temperature and salinity on growth rates of germlings of threeFucus species from iceland, helgoland and the north adriatic sea

The growth rate of germlings of three Fucus species (F. distichus subsp, edentatus from Iceland, F. vesiculosus from Helgoland, North Sea, and F. virsoides from the North Adriatic Sea) has been investigated under different temperature and salinity conditions. The highest growth rate and the maximum elongation factor were found at 9 ° C for F. distichus; in the other two species growth increased with increasing temperature. Growth decreases with dilution in the three species under consideration. A rather low tolerance to dilution was observed in F. vesiculosus germlings. In view of the overall distribution of the latter species the opposite was expected. It seems likely, however, that susceptible strains have developed at Helgoland, where salinity rarely drops below 30 %o.
