Comportamento de forrageamento de visitantes florais em Triumfetta semitriloba ...
Collevatti, Rosane GarciaEste trabalho foi desenvolvido com o objetivo de estudar o comportamento de forrageamento dos principais polinizadores de Triumfetta semitriloba, quanto aos fatores que influenciam na freqüência de visita aos ramos floridos, padrão temporal de utilização de pólen e néctar, padrão de movimentação em relação à direção e distância interplantas e regras de decisão de partida das plantas. Para tanto, foram identific...

Amaral, Tatiana Souza do; Santos, Juliana Silveira dos [UNESP]; Rosa, Fernanda Fraga; Pessôa, Marcelo Bruno; Chaves, Lázaro JoséMade available in DSpace on 2021-06-25T11:11:53Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-02-04; Plants are one of the most vulnerable groups to fragmentation and habitat loss, that may affect community richness, abundance, functional traits, and genetic diversity. Here, we address the effects of landscape features on adaptive quantitative traits and evolutionary potential, and on neutral genetic d...
Dismantling Brazil's science threatens global biodiversity heritage
Fernandes, G. Wilson; Vale, M. M.; Overbeck, Gerhard Ernst; Bustamante, Mercedes M.C.; Grelle, Carlos Eduardo V.Viveiros; Bergallo, H. G.In the middle of a political and fiscal crisis, the Brazilian government is applying successive budget cuts, including in science funding. Recent cuts radically affect research programs on biodiversity that are crucial components for the design and monitoring of public policies for nature conservation and sustainable development. We analyze the consequences of such cuts on the Research Program on Biodiversity (...
Contrasting patterns of genetic structure in Caryocar (Caryocaraceae) congeners...
Collevatti, Rosane Garcia; Leoi, Lélia C.T.; Leite, Sueane A.; Gribel, RogérioIn the present study, we compare the genetic structure of a flooded forest tree Caryocar microcarpum and a terra firme forest tree Caryocar villosum in the lower Rio Negro region and test the hypothesis that the Rio Negro, the largest tributary on the left bank of the Amazon River, has been acting as a geographical barrier to gene flow between populations from the left and right banks. Seventeen adult individua...
Swine and poultry pathogens: The complete genome sequences of two strains of My...
Vasconcelos, Ana Tereza; Ferreira, Henrique Bunselmeyer; Bizarro, Cristiano Valim; Bonatto, Sandro L.; Carvalho, Marcos O.; Pinto, Paulo MarcosThis work reports the results of analyses of three complete mycoplasma genomes, a pathogenic (7448) and a nonpathogenic (J) strain of the swine pathogen Mycoplasma hyopneumoniae and a strain of the avian pathogen Mycoplasma synoviae; the genome sizes of the three strains were 920,079 bp, 897,405 bp, and 799,476 bp, respectively. These genomes were compared with other sequenced mycoplasma genomes reported in the...
Effects of Brazil's political crisis on the science needed for biodiversity con...
Magnusson, William Ernest; Grelle, Carlos Eduardo V.Viveiros; Marques, Márcia Cristina Mendes; Rocha, Carlos Frederico D. daThe effects of Brazil's political crisis on science funding necessary for biodiversity conservation are likely to be global. Brazil is not only the world's most biodiverse nation, it is responsible for the greater part of the Amazon forest, which regulates the climate and provides rain to much of southern South America. Brazil was a world leader in satellite monitoring of land-use change, in-situ biodiversity m...
Anatomy of the floral, bract, and foliar nectaries of Triumfetta semitriloba (T...
Meira, Renata Maria Strozi Alves; Azevedo, Aristéa Alves; Araújo, João Marcos de; Silva, Kellen Lagares Ferreira; Leitão, Carlos André EspoladorTriumfetta semitriloba Jacq. (Tiliaceae) is a tropical weedy species with floral nectaries and glands located at the margins of the leaves. The objectives of this work were to describe the anatomy of these secretory structures and to analyze their exudates. Sucrose, glucose, and fructose were identified in the product released by these secretory structures, characterizing them as nectaries. The nectaries of T. ...
