Mating patterns of a subdivided population of the andean oak (Quercus humboldtii Bonpl., Fagaceae).
Mating patterns play a critical role in the maintenance of genetic variation. We analyzed the mating system in a recently fragmented population of the Andean oak (Quercus humboldtii) using four microsatellite loci. Five fragments in northeastern Colombia, South America, were selected consisting of 30.4 trees on average. We sampled about 30 seeds from three target trees in each fragment and geno...
متن کاملEffect of seed weight, light regime and substratum microsite on germination and seedling growth of Quercus semiserrata Roxb
Seeds of Quercus semiserrata Roxb. vary widely in weight, and can be classified into small (<5 g), intermediate (5 to 8 g) and heavy (>8 g) classes. Heavy seeds contain greater reserves of protein, carbohydrate, lipid and energy than intermediate-weight and small seeds. Seed weight has a strong effect on germination. Heavy seeds germinate early and show better germination than small seeds both ...

متن کاملMejora del Funcionamiento de Sistemas de Diálogo Hablado Mediante Reconocimiento del Estado Emocional de Usuarios
In this paper we propose a new technique to enhance the performance of spoken dialogue systems by means of recognising users’ emotional states. The technique employs two fusion modules that combine emotional predictions. The former employs a number of fusion methods to combine predictions made by classifiers that deal with different types of information regarding each sentence uttered by the us...
