O objetivo deste trabalho é verificar a influência da existência de uma linha cola Poliacetato Vinila (PVAc) em seção quadrada composta viga maçaranduba (Manilkara spp.). A escolha espécie foi devido disponibilidade no mercado madeireiro região Açailândia – MA. Para proceder à determinação do teor umidade madeira e resistência flexão dos corpos prova (CPs), foram realizados ensaios com vigas si...

In this work, we report on the population genetic structure of the endangered tree species Manilkara huberi, an Amazonian tree species intensely exploited due to the high density and resistance of its wood. We investigated the patterns of spatial distribution, genetic structure, and mating system using 7 microsatellite loci and here discuss the consequences for conservation and management of th...

Although different genotypes of mamey sapote with distinct pulp colors are consumed in countries from Central to South America, in-depth knowledge on genotype-related differences of their carotenoid profile is lacking. Since the fruit was found to contain the potentially vitamin A-active keto-carotenoids sapotexanthin and cryptocapsin, we sought to qualitatively and quantitatively describe the ...

The decomposition rates and mass of fine (< 10-cm-diameter) and coarse (> 10-cm-diameter) woody detritus were measured in the dry tropical forests of the northeastern Yucatan Peninsula. The smallest mass of woody detritus was found in undisturbed stands: fine fractions averaged 4.7 Mg ha-' and coarse fractions ranged between 13 and 38 Mg ha-I. The largest mass of fine woody detritus (32.2 Mg h ...
