Molecular characterization of bromeliads from northeast Brazil.
Bromeliaceae is an important botany family that includes many species with economic value; demand for members of this family is increasing. However, illegal collection frequently occurs, drastically reducing the species populations; thus, it is necessary to collect and store Bromeliaceae genetic material. In this study, we identified and quantified genetic variability of the Bromeliad family us...
متن کاملMating system variation and assortative mating of sympatric bromeliads (Pitcairnia spp.) endemic to neotropical inselbergs.
PREMISE OF THE STUDY The mating system is an important component of the complex set of reproductive isolation barriers causing plant speciation. However, empirical evidence showing that the mating system may promote reproductive isolation in co-occurring species is limited. The mechanisms by which the mating system can act as a reproductive isolation barrier are also largely unknown. METHODS ...
متن کاملDiet of eared doves (Zenaida auriculata, Aves, Columbidae) in a sugar-cane colony in South-eastern Brazil.
Farmers in the Paranapanema Valley (São Paulo, Brazil) have reported problems with flocks of Eared Doves (Zenaida auriculata) eating sprouting soybeans. In this region these birds breed colonially in sugar-cane, and eat four crop seeds, using 70% of the dry weight, in the following order of importance: maize, wheat, rice, and soybeans. Three weeds (Euphorbia heterophylla, Brachiaria plantaginea...
متن کاملa study on thermodynamic models for simulation of 1,3 butadiene purification columns
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
