Genetic structure of the ornamental tetra fish species Piabucus melanostomus Holmberg, 1891 (CHARACIDAE, IGUANODECTINAE) in the Brazilian Pantanal wetlands inferred by mitochondrial DNA sequences
(Biota Neotropica, 2013-03-01) [Artigo]
A subfamília Iguanodectinae compreende um grupo de pequenos peixes neotropicais composta de dois gêneros e 11 espécies nominais amplamente distribuídas nas drenagens do Atlântico da América do Sul. Piabucus é o único gênero ...
Alteration in cellular viability, pro-inflammatory cytokines and nitric oxide production in nephrotoxicity generation by Amphotericin B: Involvement of PKA pathway signaling
(Journal of Applied Toxicology, 2013-10-11) [Artigo]
Amphotericin B is one of the most effective antifungal agents; however, its use is often limited owing to adverse effects, especially nephrotoxicity. The purpose of this study was to evaluate the effect of inhibiting the ...
Germination of Styrax camporum Pohl. seeds in response to substrate types, moisture contents and the seed morphology
(Anais da Academia Brasileira de Ciências, 2013-03-01) [Artigo]
Este estudo avaliou a contribuição da morfologia da semente de Styrax camporum (tamanho de sementes, presença ou ausência do endocarpo aderido à semente), diferentes substratos (papel filtro, vermiculita, areia e solo: ...
In vivo evaluation of the antimutagenic and antigenotoxic effects of beta-glucan extracted from Saccharomyces cerevisiae in acute treatment with multiple doses
(Genetics and Molecular Biology, 2013-01-01) [Artigo]
Ample evidence suggests that cancer is triggered by mutagenic damage and diets or supplements capable of reducing such incidences can be related to the prevention of neoplasy development or to an improvement in life quality ...
Chromosomal organization and evolutionary history of Mariner transposable elements in Scarabaeinae coleopterans
(Molecular Cytogenetics, 2013-11-29) [Artigo]
Background: With the aim to increase the knowledge on the evolution of coleopteran genomes, we investigated through cytogenetics and nucleotide sequence analysis Mariner transposons in three Scarabaeinae species (Coprophanaeus ...
Social wasp-flower visiting guild interactions in less structurally complex habitats are more susceptible to local extinction
(Sociobiology, 2013-09-01) [Artigo]
Several studies have shown that habitat complexity is an important factor for the dynamic and stability of interacting species. However, it is not known how the habitat complexity may affect the tolerance of wasp-flower ...
Monitoring muscle damage markers during a four-week downhill walking exercise program
(Motriz: Revista de Educação Física, 2013-01-01) [Artigo]
Eccentric-based exercise is known to induce muscle damage (MD). The purpose of this study was to investigate effect of downhill walking (DW) sessions on MD and aerobic markers in young adults. Eight male subjects were ...
Influence of Apis mellifera L. (Hymenoptera: Apidae) on the Use of the Most Abundant and Attractive Floral Resources in a Plant Community
(Neotropical Entomology, 2013-12-01) [Artigo]
Some factors influence the distribution of abundance of floral visitors, especially the amount and quality of the floral resources available, the size of the area occupied by the visitor, habitat heterogeneity, and the ...
Frugivory by the White-bearded Manakin (Manacus manacus, Pipridae) in restinga forest, an ecosystem associated to the Atlantic forest
(Biota Neotropica, 2013-04-01) [Artigo]
Os tangarás (Pipridae) são um dos grupos de aves frugívoras e dispersoras de sementes mais abundantes em estratos baixos das florestas neotropicais. Neste trabalho descrevemos os frutos consumidos pela rendeira (Manacus ...
Context-dependence in seed removal by lekking and non-lekking frugivorous birds in Brazilian Atlantic forest
(Wilson Journal of Ornithology, 2013-09-01) [Artigo]
Manakins are prominent fruit-eaters and seed dispersers in the Neotropics. Most manakin species establish lek areas where males devote long periods of time displaying to attract mates, interspersed with brief absences to ...
