The microalga incorporated photobioreactor is a highly efficient biological system for converting CO2 into biomass. Using microalgal photobioreactor as CO2 mitigation system is a practical approach for elimination of waste gas from the CO2 emission. In this study, the marine microalga Chlorella sp. was cultured in a photobioreactor to assess biomass, lipid productivity and CO2 reduction. We als...

We estimated the phylogenetic position of the pseudosegmented ribbon worm Annulonemertes minusculus to test proposed evolutionary hypotheses to explain these body constrictions. The analysis is based on 18S rDNA sequences and shows that the species belongs to an apomorphic clade of hoplonemertean species. The segmentation has no phylogenetic bearing as previously discussed, but is a derived cha...

A parasitological survey was carried out on a sample of sixty mutton snappers (Lutjanus analis) that were caught on the coast of Alagoas, northeastern Brazil. The parasite diversity and infection levels were low. The ectoparasite Rocinela signata Schioedte & Meinert, 1879 (Isopoda: Aegidae), and larvae of two endoparasites, Trypanorhyncha gen. sp. and Hysterothylacium sp. (Nematoda: Anisakidae)...

The endoparasite fauna of Astyanax fasciatus from the upper São Francisco river was investigated and ecological parameters and morphological and morphometric data on the parasites are presented. A total of 74 specimens of banded astyanax were collected downstream from the Três Marias dam, municipality of Três Marias, Minas Gerais (18°12'32"S, 45°15'41"W) in January 2011 and January 2012. Eleven...

Executive Summary A preliminary trial was undertaken to determine if there are appropriate parasites in broadbill swordfish (Xiphias gladius) for testing residency hypotheses and stock relationships. The gills and guts of 34 swordfish, eight from New Caledonia, 10 from Australia (Queensland), and 16 from New Zealand, were examined for parasites. Three species of monogenean were found on the gil...

Between January and August 2012, thirty specimens of Cynoscion guatucupa (Cuvier, 1830) caught off coast of the municipality of Itajaí, state of Santa Catarina, Brazil (26° 54' 28″ S and 48° 39' 43″ W) and commercialized in the state of Rio de Janeiro were investigated for the presence of zoonotic nematodes. In total 853 larvae of four nematode parasite species were found. There were three spec...

The anthelminthic activity of the essential oil (EO) of Piper aduncum L. was tested in vitro on eggs and larvae of resistant (Embrapa2010) and susceptible (McMaster) isolates of Haemonchus contortus. The EO was obtained by steam distillation and its components identified by chromatography. EO concentrations of 12.5 to 0.02 mg/mL were used in the egg hatch test (EHT) and concentrations of 3.12 t...
