ABSTRACT

Abstract speciesLink is a large-scale biodiversity information portal that exists thanks to a broad collaborative network of people and institutions. CRIA's involvement with the scientific community of Brazil and other countries is responsible for the significant results achieved, currently reaching more than 15 million primary biodiversity data records, 95% of which are associated with preserved specimens and about 25% with high-quality digital images. The network provides data on over 200,000 species, of which over 110,000 occur in Brazil. This article describes thematic networks within speciesLink, as well as some of the most useful tools developed. The importance and contributions of speciesLink are outlined, as are concerns about securing stable budgetary support for such biodiversity data e-infrastructures. Here we review the value of speciesLink as a major source of biodiversity information for research, education, informed decision-making, policy development, and bioeconomy.


Resumo speciesLink é um portal de informações em larga escala sobre biodiversidade, que existe graças a uma ampla rede colaborativa de pessoas e instituições. O envolvimento do CRIA com a comunidade científica do Brasil e de outros países é responsável pelos resultados expressivos alcançados, atingindo atualmente mais de 15 milhões de registros de dados primários de biodiversidade, sendo 95% associados a espécimes preservados e cerca de 25% a imagens digitais de alta qualidade. A rede fornece dados sobre mais de 200.000 espécies, das quais mais de 110.000 ocorrem no Brasil. Este artigo descreve as redes temáticas do speciesLink, bem como algumas das ferramentas mais úteis desenvolvidas. A importância e as contribuições do speciesLink são destacadas, assim como as preocupações em garantir um apoio financeiro estável para e-infraestruturas de dados sobre biodiversidade. Aqui revisamos o valor do speciesLink como uma das principais fontes de informação sobre biodiversidade para pesquisa, educação, tomada de decisão, desenvolvimento de políticas e bioeconomia.

ABSTRACT

The fatty acid profiles of several fungi of the order Mucorales (Zygomycetes), including "Backusella lamprospora" (Lendner) Benny and R. K. Benj., "Benjamiella youngii" P.M. Kirk, "Circinella simplex" van Tieghem, "Cunninghamella blakesleeana" Lendner, "Mortierella ramanniana" (Möller) Linnem., "Mucor circineloides" f. "janssenii" (Lendner) Schipper, "Mycotypha microspora"Fenner, "Rhizomucor miehei" (Cooney and R. Emerson) Schipper and "Rhizomucor pusillus"(Lindt) Schipper, and of "Volutella"sp. Fr., from the class Ascomycetes, were qualitatively analysed by gas-liquid chromatography in order to determine the taxonomic value of these chemotaxonomic markers. The fatty acids present in all strains were palmitic (16:0), oleic (18:1), linoleic (18:2) and kappa-linoleic (18:3) acid, with the exception that the later was not found in "Volutella" sp. Chemotaxonomic markers for some species and genera were obtained, including a non-identified fatty acid, FAME8 (minimum and maximum of 16.53 and 16.61 minutes) for "Benjaminiella youngii CCT4121. Thechemotaxonomic marker of the order Mucorales was the fatty acid 18:3ômega6, confirming previous data from literature. The results of the present study that qualitative fatty acid analysis can be an important chemotaxonomic tool for the classification of the fungi assigned to the order Mucorales (Zygomycetes).
