Morphological integration refers to the modular structuring of inter-trait relationships in an organism, which could bias the direction and rate of morphological change, either constraining or facilitating evolution along certain dimensions of the morphospace. Therefore, the description of patterns and magnitudes of morphological integration and the(More)
Changes in patterns and magnitudes of integration may influence the ability of a species to respond to selection. Consequently, modularity has often been linked to the concept of evolvability, but their relationship has rarely been tested empirically. One possible explanation is the lack of analytical tools to compare patterns and magnitudes of integration(More)
A síntese de derivados do tianfenicol, catalisada por lipases, foi investigada através da realização das reações de acilação e de hidrólise, como abordagens complementares, sendo a lipase Candida antarctica B o biocatalisador mais eficiente para as modificações seletivas de ambos, o tianfenicol e o correspondente diacetato do tianfenicol, respectivamente.(More)
O fungo fitopatogênico Lasiodiplodia theobromae, isolado de goiaba, foi cultivado em arroz por 32 dias à temperatura ambiente. Extração com CH 2 Cl 2 :MeOH (3:7), seguido de fracionamento cromatográfico do extrato forneceu o esteróide ergosterol. Da cultura fúngica em meio de Czapeck por 40 dias à temperatura ambiente, foram isolados a isocumarina(More)
The objective of this study was to evaluate the reproductive and productive performance of Santa Inês ewes bred at different times of the year in humid tropical climate. One hundred and forty-eight Santa Inês ewes were grouped according to the time of the year of their breeding season (i.e., mating period) (dry/wet, wet, wet/dry, and dry season). The(More)
Whole cells from the Brazilian beans feijão da corda (Vigna unguiculata) have been employed as biocatalyst in different bioreduction processes. Good to excellent selectivities can be obtained in the reduction of aromatic and aliphatic ketones, as well as βketoesters, depending the conversions and the chemoselectivity on the substrate structure. This(More)
