¿Los aportes nutricionales de los frutos marcan el tipo de dispersión de las especies vegetales de bosque seco?

Abstract

In the present study was evaluated the moisture content, pulp, protein, fat, carbohydrate, ash and Brix fruit dry forest of southwestern Ecuador, as important elements in the diet of birds, mammals and other frugivorous present in the collection habitat. We worked with two types of fruits; legumes and fleshy fruits in total there were 18 species, 11 of fleshy fruits and seven of legumes, fruits of each species were collected according to seasonal stages of fruiting, considering the characteristics of the fruits and information about consumption by animals. To determine the nutritional content of fruits collected several chemical methods, with which the moisture content (gravimetric), pulp content (gravimetry), protein (Kjeldahl method), carbohydrates (formula by difference), ° Brix (refractometer), lipids (Soxhlet method) and minerals (gravimetry). Chloroleucon mangens was the species with the highest protein content (20.92%), Achaetocarpus pubescens had the highest sugar content (39.76%), Senna mollissima maximum fat (11.88%) and ash (11.88 %), the species with the highest content of pulp and water was Vasconcellea parviflora (0.93% and 77.00% respectively).
