Introducción: Los estudios de coral negro en Centroamérica son escasos. No se ha publicado nada sobre las especies, hábitats, distribución e importancia del El Salvador. A pesar que Antipathes sido reportado como uno los géneros sucumbido a la presión antrópica. Objetivos: Identificar especies corales negros Cóbanos, Salvador, y caracterizar cualitativamente abundancia el tamaño colonias; ident...

The genus Cellulophaga is composed of obligate aerobic Gram-negative bacteria commonly found in association with marine algae. We report the approximately 4.42-Mbp draft genome sequence of Cellulophaga sp. E6, which inhibits N-(3-oxododecanoyl)-l-homoserine lactone (3-oxo-C12-HSL)-mediated quorum sensing (QS), lasB transcription, and biofilm formation by Pseudomonas aeruginosa.

The Lower Miocene deposits in Gabal Gharra, Cairo – Suez District, unconformably overlies the Oligocene and Eocene deposits. They consist predominantly of regressive and transgressive mixed siliciclastic / carbonate sediments of shallow marine environments. The Lower Miocene deposits are represented lithostratigraphically by the Gharra Formation that comprises four members, from base to top: Ag...

The recently described epizoic sponge-sponge symbioses between Xestospongia deweerdtae and two species of Plakortis present an unusual series of sponge interactions. Sponges from the genus Plakortis are fierce allelopathic competitors, rich in cytotoxic secondary metabolites, and yet X. deweerdtae flourishes as an epizoic encrustation on Plakortis deweerdtaephila and Plakortis symbiotica. Our o...

Sea turtles are known to host diverse communities of plants and invertebrate animals (Caine 1986; Kitsos et al. 2005; Robinson et al. 2017). Past analyses of the size, abundance, and/or species composition of the organisms present on an individual turtle have provided insight into the health (e.g. Flint et al. 2009), habitat use (e.g. Pfaller et al. 2014), and movement (e.g. Killingley and Lutc...

Because seaweeds uncontrolled by herbivores can overgrow and kill corals, competition can exclude corals from temperate latitudes where herbivores generally fail to control seaweed biomass. In this study, we show that the coral Oculina arbuscula persists on reefs in temperate North Carolina where seaweeds are common by harboring the omnivorous crab Mithrax forceps, which removes seaweeds and in...

The health status of 83 loggerhead sea turtles (Caretta caretta; 39 foraging, 31 nesting, and 13 stranded turtles) was analyzed using physical examinations, hematology, plasma biochemistry, plasma protein electrophoresis, and toxicologic parameters. Significant differences were noted in a number of health parameters between turtles exhibiting each of these behaviors. On physical examinations, s...
