| In this paper, we summarize the diversity of Polyphysaceae species in Todos os Santos Bay, in the state of Bahia, Brazil. On the basis of ten years of collections and the analysis of herbarium material, six species have been recorded for the area: Acetabularia caliculus J.V.Lamour. in Quoy & Gaimard; A. crenulata J.V.Lamour.; A. schenckii Möbius; Parvocaulis myriosporus (Joly & Cord.-Mar.) C.W.N.Moura & J.C.De Andrade comb. nov.; P. pusillus (M.Howe) Berger et al.; and P. parvulus (Solms) S. Berger et al. The last has a distribution extending to the southern Atlantic Ocean. Acetabularia myriospora was transferred to Parvocaulis (as P. myriosporus) on the basis of its short corrugated peduncles and lack of a lower corona in the... |

| Laboratory incubation experiments and shipboard measurements on the Southern Atlantic Ocean have provided the first evidence for marine production of monoterpenes. Nine marine phytoplankton monocultures were investigated using a GC-MS equipped with an enantiomerically-selective column and found to emit at rates, expressed as nmol C(10)H(16) (monoterpene) g [chlorophyll a](-1) day(-1), from 0.3 nmol g [chlorophyll a](-1) day(-1) for Skeletonema costatum and Emiliania huxleyi to 225.9 nmol g [chlorophyll a](-1) day(-1) for Dunaliella tertiolecta. Nine monoterpenes were identified in the sample and not in the control, namely: (-)-/(+)-pinene, myrcene, (+)-camphene, (-)-sabinene, (+)-3-carene, (-)-pinene, (-)-limonene and p-ocimene. In addition, shipboard... |
