Directed vertebrate‐mediated seed dispersal of a fleshy‐fruited amaryllid in a heterogenous habitat
نویسندگان
چکیده
Most plants with fleshy fruits have seeds that are ingested by animals, but a less well-understood mode of seed dispersal involves containing discarded frugivorous animals because they too large or toxic to be ingested. We studied the biology Haemanthus deformis, an amaryllid lily species found in mosaic bush clumps grassland matrix South Africa. asked whether is directed and among germination survival greater for dispersed than those into grassland. Using camera trapping, we consumed mainly birds rodents. The pulp was removed from which were then without ingestion. While many close parent plant, most (c. 78.5%) further 1 m away plant. Longer distance resulted flying off their bill rodents engaging scatter-hoarding behavior. Seedling successful within as compared grasslands shade identified primary requirement seedling survival. Seeds fruit had been germinated faster intact fruits. deformis deploys system dispersal, whereby both contribute patchy favorable

Advantages of seed dispersal: A re-evaluation of directed dispersal
Seed dispersal can be advantageous (1) in escape from densityor distance-dependent seed and seedling mortality, (2) by colonization of suitable sites unpredictable in space and time, and (3) by directed dispersal to particular sites with a relatively high probability of survival. Most previous research on the consequences of seed dispersal has focused on escape and colonization because adaptati...
متن کاملDirected seed dispersal by bellbirds in a tropical cloud forest.
A fundamental goal of plant population ecology is to understand the consequences for plant fitness of seed dispersal by animals. Theories of seed dispersal and tropical forest regeneration suggest that the advantages of seed dispersal for most plants are escape from seed predation near the parent tree and colonization of vacant sites, the locations of which are unpredictable in space and time. ...

پیدایش مرحله ی جدیدی از نظام سرمایه داری بعد از جنگ جهانی دوم همزمان است با ظهور عصر اطلاعات و رسانه جمعی. در چنین جامعه ای سیر آزادانه ی نشانه ها در فضای بی اساس مجازی بر سرعت فرسایش واقعیت می افزاید. به اعتقاد بودریار، فقدان واقعیت به واسطه ی شبیه سازی آن و تولید حاد واقعیت (hyperreality) پنهان خواهد ماند. این پژوهش بر آن است که جامعه فرانوین توصیف شده در سه رمان بریان مور را با توجه به نظر...

During last two decades studies on endozoochorous seed dispersal indicated that a large numbers of plant seeds are potentially dispersed and suceefully germinated via animal dung. However, very little is known about the relative importance of endozoochory in germination success of plant species in semi-steppe rangelands. In this paper we examined dung germinating seed content, seed deposition p...
