Sympatry and evolution: relationships between the endemic Myrcia guarujana and the widely distributed M. spectabilis.

Myrcia spectabilis DC. has a wide distribution in the south and southeast Brazilian regions. M.

Fishers and groupers (Epinephelus marginatus and E. morio) in the coast of Brazil: integrating information for conservation.

Background: Groupers are a vulnerable but economically important group of fish, especially for small-scale fisheries. We investigated catches and local ecological knowledge (LEK) of diet, habitat, and past fishing experiences.

Methods: Landings, prices, interviews, and restaurants demand for two species, Epinephelus marginatus (dusky grouper) and Epinephelus morio (red grouper), were registered.

Isolation and characterization of nine polymorphic microsatellite loci in Piper solmsianum (piperaceae).

Premise Of The Study: Nine microsatellite (simple sequence repeat [SSR]) loci were characterized for natural populations of Piper solmsianum, a potential source of bioactive secondary metabolites, and analyzed to assess the levels of genetic diversity in this species. •

Methods And Results: Based on an enriched library using the oligonucleotides (CT)8 and (GT)8, a total of 19 pairs of SSR primers were designed and nine of them were highly polymorphic after screening of 37 specimens from two populations. The number of alleles per locus ranged from one to six while the observed heterozygosity for polymorphic loci ranged from 0.

Genetic structure and a selected core set of Brazilian soybean cultivars.

Soybean is one of the most valuable and profitable oil crop species and a thorough knowledge of the genetic structure of this crop is necessary for developing the best breeding strategies. In this study, a representative collection of soybean cultivars recommended for farming in all Brazilian regions was genotyped using 27 simple sequence repeat (SSR) loci. A total of 130 alleles were detected, with an average allelic number of 4.

Isolation and characteristics of eight novel polymorphic microsatellite loci in Lippia alba (Verbenaceae).

Premise Of The Study: A set of eight microsatellite (simple sequence repeat [SSR]) markers for Lippia alba, an important medicinal and cosmetic plant, was developed to aid studies of genetic diversity and to define efficient strategies for breeding programs.

Methods And Results: Using a (CT)(8)- and (GT)(8)-enriched library, a total of 11 SSR loci were developed and optimized in L. alba.
