Determinants 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 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...
متن کاملTaste and Physiological Responses to Glucosinolates: Seed Predator versus Seed Disperser
In contrast to most other plant tissues, fleshy fruits are meant to be eaten in order to facilitate seed dispersal. Although fleshy fruits attract consumers, they may also contain toxic secondary metabolites. However, studies that link the effect of fruit toxins with seed dispersal and predation are scarce. Glucosinolates (GLSs) are a family of bitter-tasting compounds. The fleshy fruit pulp of...
متن کاملSeed Disperser Effectiveness: the Quantity Component and Patterns of Seed Rain for Prunus Mahaleb
In this paper we analyze the seed dispersal stage of the Prunus mahaleb–frugivorous bird interaction from fruit removal through seed delivery within the context of disperser effectiveness. The effectiveness of a frugivorous species as a seed disperser is the contribution it makes to plant fitness. Effectiveness depends on the quantity of seed dispersed (‘‘quantity component’’) and the quality o...
متن کاملFarmer’s seed sources and seed quality: 2. seed health
The study assessed the health quality of wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) seed samples collected from formal and informal sector in Ethiopia and Syria. In Ethiopia, several seed-borne fungi were found on wheat samples: Cochliobolus sativum, Fusarium avenaceum, F. graminearum, F. nivale, F. poae and Septoria nodorum. C. sativum was predominant with 84% of samples...
