RESUMO
A list of amphibian and reptile species that occur in open and forested areas of the Atlantic Forest in the municipality of Cruz das Almas, in the Recôncavo Baiano, eastern Brazil is presented. Field sampling occurred between January 2015 to March 2019, totalling 117 samples distributed in three areas: Parque Florestal Mata de Cazuzinha, Mata da Cascalheira, and Riacho do Machado. A total of 1,848 individuals of 69 species (31 anurans, 14 lizards, 19 snakes, two amphisbaenians, and three testudines) was recorded. Additionally, one individual of Ophiodesstriatus was found in Mata da Cascalheira after the end of sampling, totalling 15 lizard species and 70 herpetofaunal species. The prevalence of open-area species and the presence of Phyllopezuslutzae, Diploglossuslessonae, and Dryadosauranordestina in interior forest patches are discussed. Additionally, a new record of the invasive terrapin Trachemysdorbigni in the State of Bahia is reported.
RESUMO
Two methods for the extraction, identification and quantification of the highest occurrence and lowest perception threshold off-flavours in fifteen different samples of Brazilian Pilsner beers were developed. For this purpose, headspace solid phase microextraction in combination with a gas chromatography coupled to a mass spectrometric detection (HS-SPME-GC-MS) as well as headspace extraction in combination with a gas chromatography coupled to electron capture detection (HS-GC-ECD) were evaluated. The first and the second methods were used for esters and vicinal diketones analysis, respectively. All data were comprehended below the taster's threshold detection limit: ethyl acetate 39.48 ng mL(-1) (RSD mean value 4.2%), isoamyl acetate 3.88 ng mL(-1) (RSD mean value 3.4%), ethyl hexanoate 0.61 ng mL(-1) (RSD mean value 3.1%) and 2,3-butanedione 0.10 ng mL(-1) (RSD mean value 2.9%). The validated method demonstrated to be useful for the analysis of highest incidence beer off-flavours.
