Effects of Nutritional and Anti-Nutritional Properties of Seeds on the Feeding Ecology of Seed-Eating Birds of the Monte Desert, Argentina

Animal populations often decline due to habitat disturbance, but the initial response of organisms to human-induced environmental change is usually behavioral. Intra- and inter-specific interactions can restrict or facilitate access to resources, resulting in changes to individual fitness, and resource depletion may affect the frequency and strength of interactions. In birds, it is often assumed that feeding in groups increases foraging efficiency. We assessed how the reduction of seed resources provoked by cattle grazing affected different properties of seed-eating bird flocks in woodlands having the same structural characteristics but differing in seed abundance. Under lower availability of grass seeds (i.e., under grazing), flocks were smaller and less rich and birds showed a lower flocking propensity. This pattern could be explained by three non-exclusive hypotheses. Food reduction caused by grazing (i) decreases the number of seed-eating birds and concomitantly generates smaller flocks; (ii) reduces the density of nuclear species, decreasing the group cohesion in large flocks; (iii) makes large flocks less attractive by increasing individual competence for food. Our results provide evidence that cattle grazing affect the interactions of seed-eating birds and suggest the importance of understanding flocking behavior to bring about management actions.

Abstract: Manabí and Ecuadorian population in general are consumers of tomato paste in different forms, so that producers and industrial product processing always looking to have a high quality and good prices for the benefit of its customers. This research based on the results obtained, it leaves a number of very valuable conclusions for determining the carrot pulp will have a positive impact on the physical, chemical and organoleptic, when combined with the tomato paste features, without diminishing or provide a look that could adversely affect its commercial presentation to the client. The objective of this research was to get the development of a tomato paste mixed with carrot paste, with the purpose of obtaining an improved nutritional properties (fiber and beta-carotene) for the benefit of the consumer. Index Terms: Pasta, tomato, carrot, consistency, nutritional properties.
