Primeiro registro de peixe anual endêmico de ambiente semiárido no Nordeste do Brasil

Studies focusing the biology of annual fish are still scarce, and in the case of threatened species, research, as well as the adoption of protective measures for these populations, are needed. We present herein the first record of Hypsolebias antenori (Cyprinodontiformes: Cynolebiidae) in temporary pools of Lajedo de Soledade, located in a semiarid region, in Northeastern Brazil. Five individuals (two males and three females) were captured in three temporary pools in May 2017. For the capture, a sieve (50 x 50 cm) with a 4 mm of mesh size was used. The males showed a total length ranging from 3.5 to 4.7 cm (average: 4.1 cm) and body mass amplitude between 0.38 to 0.94 g (average: 0.66 g). The females had a total length from 3.5 to 3.9 cm (average: 3.67 cm) and body mass amplitude of 0.55 to 0.70 g (average: 0.64). Considering that the collection area is one of the most important archaeological sites in Brazil, this endemic species of Caatinga demonstrates the importance of conservation of the environment and serves to support the preservation of the present area that is not recognized and registered as cultural and environmental patrimony.Keywords: Karst, Jandaíra Formation, Caatinga, temporary pools, Cynolebiidae, Hypsolebias antenori.Estudos que enfocam a biologia de peixes anuais ainda são escassos e, no caso de espécies ameaçadas, são necessárias pesquisas, bem como a adoção de medidas de proteção para essas populações. Apresenta-se, neste trabalho, o primeiro registro de Hypsolebias antenori (Cyprinodontiformes: Cynolebiidae) em poças temporárias do Lajedo de Soledade, localizado em uma região semiárida, no Nordeste do Brasil. Cinco indivíduos (dois machos e três fêmeas) foram capturados em três piscinas temporárias em maio de 2017. Para a captura, foi utilizada uma peneira (50 x 50 cm) com 4 mm de tamanho de malha. Os machos apresentaram comprimento total variando de 3,5 a 4,7 cm (média: 4,1 cm) e amplitude de massa corporal entre 0,38 a 0,94 g (média: 0,66 g). As fêmeas tinham comprimento total de 3,5 a 3,9 cm (média: 3,67 cm) e amplitude de massa corporal de 0,55 a 0,70 g (média: 0,64). Considerando que a área de coleta é um dos mais importantes sítios arqueológicos do Brasil, essa espécie endêmica da Caatinga demonstra a importância da conservação do meio ambiente e serve para apoiar a preservação da área atual que não é reconhecida e registrada como patrimônio cultural e ambiental.

FungalTraits:A user-friendly traits database of fungi and fungus-like stramenopiles

The cryptic lifestyle of most fungi necessitates molecular identification of the guild in environmental studies. Over the past decades, rapid development and affordability of molecular tools have tremendously improved insights of the fungal diversity in all ecosystems and habitats. Yet, in spite of the progress of molecular methods, knowledge about functional properties of the fungal taxa is vague and interpretation of environmental studies in an ecologically meaningful manner remains challenging. In order to facilitate functional assignments and ecological interpretation of environmental studies we introduce a user friendly traits and character database FungalTraits operating at genus and species hypothesis levels. Combining the information from previous efforts such as FUNGuild and Fun(Fun) together with involvement of expert knowledge, we reannotated 10,210 and 151 fungal and Stramenopila genera, respectively. This resulted in a stand-alone spreadsheet dataset covering 17 lifestyle related traits of fungal and Stramenopila genera, designed for rapid functional assignments of environmental studies. In order to assign the trait states to fungal species hypotheses, the scientific community of experts manually categorised and assigned available trait information to 697,413 fungal ITS sequences. On the basis of those sequences we were able to summarise trait and host information into 92,623 fungal species hypotheses at 1% dissimilarity threshold

Arbuscular mycorrhizal fungi and indolebutyric acid alter rooting rate and physiological characteristics of Lantana camara L. (Verbenaceae)?

ABSTRACT The objective of this study was to evaluate the rooting and some physiological characteristics of Lantana camara L. (Verbenaceae) stakes in different concentrations of indolebutyric acid (IBA) and its association with the arbuscular mycorrhizal fungi (AMF) Claroideoglomus etunicatum (W.N. Becker & Gerd.) C. Walker & A. Schüssler e Gigaspora albida N.C. Schenck & G.S. Sm. The experimental design was completely randomized in a 3x3 factorial scheme with three replicates, where the first factor was the AMF and the second factor by doses of IBA (0; 1.0 and 1.5 mg .mL-1). The results showed that the presence of AMF in the substrate, as well as the IBA, isolated or in association stimulates the rooting and some physiological characters of L. camara cuttings

La taxonomie et l’analyse phylogénétique révèlent un nouveau genre et trois nouvelles espèces dans Inonotus s.l. (Hymenochaetaceae) du Brésil

During surveys in the Brazilian Amazon, Atlantic Forest and Caatinga, several species of poroid Hymenochaetaceae were collected. Of the collected specimens, ITS and LSU sequences were generated and phylogenetic analyses performed. From morphological and phylogenetic inferences, Sclerotus Xavier de Lima, gen. nov. is described based on collections of Phellinus extensus, while Inonotus parvisetus V.R.T. Oliveira, Xavier de Lima & Gibertoni, sp. nov., Tropicoporus flabellatus V.R.T. Oliveira, J.R.C. Oliveira-Filho, Xavier de Lima & Gibertoni, sp. nov and T. nullisetus Xavier de Lima, V.R.T. Oliveira & Gibertoni, sp. nov. are described as new species. Sclerotus gen. nov. is characterized by the strongly ventricose hymenial setae and the black line that is exposed as a dark crust. Inonotus parvisetum can be differentiated from similar species of the genus by the smaller tramal setae. Tropicoporus flabellatus sp. nov. produces the thinnest basidiomata in the genus, and does not develop a dark crust in the pileus surface, while in T. nullisetus sp. nov. hymenial setae is absent. The other specimens clustered within I. micantissimus (Rick) Rajchemb., I. rickii (Pat.) Reid, T. linteus (Berk. & M.A.Curtis) L.W.Zhou & Y.C.Dai, T. stratificans G.Coelho & Yurchenko and T. tropicalis (M.J.Larsen & Lombard) L.W.Zhou & Y.C.Dai. Here T. stratificans is recorded for the first time outside the type locality. Illustrations of the species and keys for Inonotus sensu lato are provided.Au cours de prospections en Amazonie brésilienne, dans la forêt atlantique et la Caatinga, plusieurs espèces de Hymenochaetaceae poroïdes ont été collectées. Des séquences ITS et LSU ont été générées à partir des spécimens collectés et des analyses phylogénétiques ont été eff ectuées. À partir de déductions morphologiques et phylogénétiques, Sclerotus Xavier de Lima, gen. nov. est décrit sur la base de collections de Phellinus extensus, tandis qu’Inonotus parvisetus V.R.T. Oliveira, Xavier de Lima & Gibertoni, sp. nov., Tropicoporus fl abellatus V.R.T. Oliveira, J.R.C. Oliveira-Filho, Xavier de Lima & Gibertoni, sp. nov et T. nullisetus Xavier de Lima, V.R.T. Oliveira & Gibertoni, sp. nov. sont décrites comme de nouvelles espèces. Sclerotus gen. nov. est caractérisé par les soies hyméniales fortement ventriculaires et la ligne noire qui est exposée comme une croûte sombre. Inonotus parvisetum peut être diff érencié des espèces similaires du genre par les soies tramales plus petites. Tropicoporus fl abellatus sp. nov. produit les basidiomes les plus minces du genre et ne développe pas de croûte sombre à la surface du chapeau, tandis que dans T. nullisetus sp. nov., les soies hyméniales sont absentes. Les autres spécimens étaient regroupés dans I. micantissimus (Rick) Rajchemb., I. rickii (Pat.)
