Positive adjacency effects mediated by seed disperser birds in pine plantations.
This study examines the consequences of adjacent elements for a given patch, through their effects on zoochorous dispersion by frugivorous birds. The case study consists of pine plantations (the focal patch) adjacent to other patches of native vegetation (mixed patches of native forest and shrublands), and/or pine plantations. Our hypothesis is that input of native woody species propagules gene...
متن کاملDeterminants of Seed Disperser Effectiveness: the Quantity
— In this paper we analyze the seed dispersal stage of the Prunus mahaleb1 frugivorous bird interaction from fruit removal through seed delivery within the context of 2 disperser effectiveness. The effectiveness of a frugivorous species as a seed disperser is the 3 contribution it makes to plant fitness. Effectiveness depends on the quantity of seed dispersed 4 and the quality of dispersal prov...
متن کاملEffects of landscape corridors on seed dispersal by birds.
Habitat fragmentation threatens biodiversity by disrupting dispersal. The mechanisms and consequences of this disruption are controversial, primarily because most organisms are difficult to track. We examined the effect of habitat corridors on long-distance dispersal of seeds by birds, and tested whether small-scale (<20 meters) movements of birds could be scaled up to predict dispersal of seed...
متن کاملPine Plantations and New England Forestry
ORESTRY began to be promoted in New England only a little over a quarter century ago. In that period the federal Forest Service, the several associations, and later as they became established the state departments and forest schools have built up an immense campaign of education. This publicity has largely determined the popular conception of forestry and hence the direction of its growth. Almo...
متن کاملHierarchical mechanisms of spatially contagious seed dispersal in complex seed-disperser networks.
Intra- and interspecific spatially contagious seed dispersal has far-reaching implications for plant recruitment, distribution, and community assemblage. However, logistical and analytical limitations have curtailed our understanding concerning the mechanisms and resulting spatial patterns of contagious seed dispersal in most systems and, especially, in complex seed-disperser networks. We inves...
