The Physiological Implications Of Bleaching Of Corals Off Southeast Florida, C. J. Reese, G. S. Kleppel, Richard E. Dodge

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

As part of an ongoing study of coral bleaching, observations were made of corals on reefs (ca. 8m) off John U. Lloyd Beach, Dania, FL, in December, 1987. Bleaching was evident in approximately 50% of Montastrea annularis, the dominant scleractinian coral species. Quantitative pigment measurements by HPLC show that bleached corals contained

Decline Of Coral Growth Rates At Negril, Jamaica, T. J. Goreau, Richard E. Dodge, P. D. Goreau

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Montastrea annularis heads were collected near Negril, Jamaica, along transects from open, normal reef conditions into the mouths of rivers draining the Negril Morass. Corals subject to turbidity (particulate peat and dissolved humic compouonds near rivers, re-suspended reef sediments away from them) were growing more slowly than those in normal circumstances. Surprisingly, corals growing fastest were slowing the most, and the slowest growers increasing growth rate. Linear regression analysis of growth trends over the past two decades revealed stable limit-cycle behavior: change of growth was inversely proportional to growth rate, with a very significant correlation coefficient of -0.92. We suggest …

Elasmopus Balkomanus, A New Species From The Florida Keys (Crustacea, Amphipoda), James Darwin Thomas, J. L. Barnard

Marine & Environmental Sciences Faculty Articles

Elasmopus balkomanus is described from Looe Key Reef in the Florida Keys. The species is very close to the eastern Pacific E. antennatus but in the male has equally extending rami on uropod 3, only 2 (versus 4-6) spines on each lobe of the tel son in adults, a lateral ridge on the propodus of male gnathopod 2 and very heavily armed flagella of antenna 2 in the male.

This species lives in a short-tufted algal turf community on coral rubble but apparently is rare because it has only been collected once in 10 years of sampling in the Florida …

Vadosiapus Copacabanus, A New Genus And Species Of Exoedicerotidae From Brazil (Crustacea, Amphipoda), J. L. Barnard, James Darwin Thomas

Marine & Environmental Sciences Faculty Articles

Vadosiapus copacabanus, n. gen. is described from the surf zone on the beach at Copacabana, Rio de Janeiro, Brazil. The genus and unique species is related to the three known species of Bathyporeiapus, which range southward from Brazil through the Magellan region of South America. Vadosiapus is distinguished from Bathyporeiapus in the odd phoxocephalid-like article 3 of the mandibular palp, the nonsinuate epimeron 2, the broadened tel son bearing only midsagittal armaments and the enlarged dactyl of gnathopod 2.

Ipanemidae, New Family, Ipanema Talpa, New Genus And Species, From The Surf Zone Of Brazil (Crustacea: Amphipoda: Haustorioidea), J. L. Barnard, James Darwin Thomas

Marine & Environmental Sciences Faculty Articles

A new family of haustorioid Amphipoda resembling the Phoxocephalopsidae and Urothoidae has been discovered in sands of the surf zone off Rio de Janeiro, Brazil. Like the recently described Cheidae, the new speciesgenus- family combines various characters of haustorioids in a unique manner and bears one unprecedented apomorphic character: an alate, uncleft telson.

The new taxon has the following characters of Urothoidae: antenna 2, head, and distal parts of pereopods but has a distinctive antenna I, coxae 1-2, mandibular palp, telson and epimera 1-2. Ipanema has the following characters of Phoxocephalopsidae: coxae, mandibles, and uropod I but has distinctive antennae …
