Personal BioBlitz: A New Way to Encourage Biodiversity Discovery and Knowledge in K-99 Education and Outreach
No full textBroad and detailed knowledge about common species in everyday life has decreased among the public. Even biology researchers may be largely unaware of our everyday biodiversity. To counter such 'species blindness' and create long-term excitement and learning about the biodiversity we see every day, we arranged 76-day BioBlitzes at Rutgers University (New Jersey, USA) in 2014 and 2015 where participants identified and listed all species they discovered. The result was 7270/11748 observations from 30/78 participants and 7/13 countries, including 3458/3057 unique taxa, 91%/99.9% identified to species and 80%/54% listed only by one person (2014/2015). Observations of organismal groups did not strongly correspond to number of estimated species worldwide, but appeared to be related to perceived charisma, body size, and organism mobility. Participants reported increased ability to 'see' species and to identify new groups, learning new tools of species identification and strongly increasing their biodiversity knowledge and eagerness to learn more.Peer reviewe
The hmc-Operon of Desulfovibrio vulgaris Hildenborough encodes a potential transmembrane redox channel.
No full textThe nucleotide sequence of the hmc operon from Desulfovibrio vulgaris subsp. vulgaris Hildenborough indicated the presence of eight open reading frames, encoding proteins Orf1 to Orf6, Rrf1, and Rrf2. Orf1 is the periplasmic, high-molecular-weight cytochrome (Hmc) containing 16 c-type hemes and described before (W. B. R. Pollock, M. Loutfi, M. Bruschi, B. J. Rapp-Giles, J. D. Wall, and G. Voordouw, J. Bacteriol. 173:220-228, 1991). Orf2 is a transmembrane redox protein with four iron-sulfur clusters, as indicated by its similarity to DmsB from Escherichia coli. Orf3, Orf4, and Orf5 are all highly hydrophobic, integral membrane proteins with similarities to subunits of NADH dehydrogenase or cytochrome c reductase. Orf6 is a cytoplasmic redox protein containing two iron-sulfur clusters, as indicated by its similarity to the ferredoxin domain of [Fe] hydrogenase from Desulfovibrio species. Rrf1 belongs to the family of response regulator proteins, while the function of Rrf2 cannot be derived from the gene sequence. The expression of individual genes in E. coli with the T7 system confirmed the open reading frames for Orf2, Orf6, and Rrf1. Deletion of 0.4 kb upstream from orf1 abolished the expression of Hmc in D. desulfuricans G200, indicating this region to contain the hmc operon promoter. The expression of two truncated hmc genes in D. desulfuricans G200 resulted in stable periplasmic c-type cytochromes, confirming the domain structure of Hmc. We propose that Hmc and Orf2 to Orf6 form a transmembrane protein complex that allows electron flow from the periplasmic hydrogenases to the cytoplasmic enzymes that catalyze the reduction of sulfate. The domain structure of Hmc may be required to allow interaction with multiple hydrogenases
Contribution to the knowledge of the endemic Australian genus Binburrum Pollock, 1995 (Coleoptera: Pyrochroidae: Pilipalpinae), with description of three new species
No full textBinburrum Pollock, 1995 is a small group of fire-coloured beetles (Tenebrionoidea: Pyrochroidae: Pilipalpinae) endemic to Australia with five described species. Herein, three new species of Binburrum – B. articuno (southeastern South Australia), B. moltres (northeastern Queensland, Australia), and B. zapdos (northeastern Queensland) – are described based on comparative anatomy, highlighting the underestimated diversity of this genus. Binburrum angusticollis Pollock, 1995 is newly recorded from New South Wales, Australia. Descriptions of new species are supplemented with digital photographs and scientific illustrations of habitus and salient structures. A key for the identification of Binburrum is provided
