Seed 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...

— 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 کاملContemporary pollen and seed dispersal in a Prunus mahaleb population: patterns in distance and direction.
Pollination and seed dispersal determine the spatial pattern of gene flow in plant populations and, for those species relying on pollinators and frugivores as dispersal vectors, animal activity plays a key role in determining this spatial pattern. For these plant species, reported dispersal patterns are dominated by short-distance movements with a significant amount of immigration. However, the...

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Factors Limiting Tropical Rain Forest Regeneration in Abandoned Pasture: Seed Rain, Seed Germination, Microclimate, and Soil
Vegetation, seed rain, seed germination, microclimate, and soil physical and chemical parameters were measured in a recently abandoned pasture and adjacent primary rain forest in southern Costa Rica. The goal of this study was to assess the importance of these factors in limiting forest regeneration in abandoned pastures. Seed rain of animal dispersed species decreased dramatically in the pastu...
