We found species‐specific responses of seed production, seed dispersal traits, and predicted dispersal distances to hydrological conditions. Despite these species‐specific responses, there was a general positive relationship between seed production and dispersal distance: Plants growing in favorable ...
21. Wind and animals play an important role in the reproduction of plants. Which of the following processes make use of wind and animals? A Pollination B Fertilisation C Germination D Seed dispersal(1) A only(2) B and C only(3) B and D only(4) A and D only 相关知识点: 试题来...
Seed massIn the moist Neotropics, vertebrate frugivores have a much greater role in the dispersal of forest and successional woody plants than wind, and bats rather than birds play the dominant role in dispersing early successional species. I investigated whether these patterns also occurred in a ...
The Practice of Statistics for STEM: Primary students and pre-service primary teachers exploring variation in seed dispersal For example, in wind dispersal, release height of the diaspore is a key factor of the dispersal equation, with diaspores released from tall plants traveling farther than those...
plants were located along a ditch and not in the agricultural fields. One million seeds were shed from each source-cell throughout the seed shedding period. Primary dispersal took place by wind; seeds that were blown into a ditch after wind dispersal dispersed further by surface water. During ...
Mechanistic modeling of seed dispersal by wind over hilly terrain Seed dispersal is the main movement mechanism used by plants. The last decade saw rapid progress in understanding the underlying processes, especially for ... A Trakhtenbrot,GG Katul,R Nathan - 《Ecological Modelling》 被引量: ...
the poor conservation status of many seed-dispersing tropical animals puts plants in regions such as Southeast Asia and Madagascar most at risk today.Without the preservation of such animals,global seed dispersal could decline by a further 15 percent.(然而,如今许多散布种子的热带动物的保护状况不佳,...
How do fruits aid in seed dispersal? What is the value to society of research on genes that control flowering? Explain the importance of producing flowers and fruit. How do plants contribute to moisture in the air? What is the advantage of propagating by seeds when compared with the propagati...
Seeds are reproductive structures produced by plants that contain an embryonic plant, a store of nutrients and a protective seed coat. They are a crucial part of the plant life cycle and serve as a means of dispersing and propagating plant species. Answer and Explanation: ...
Plants cover a large fraction of the Earth’s land mass despite most species having limited to no mobility. To transport their propagules, many plants have evolved mechanisms to disperse their seeds using the wind1–4. A dandelion seed, for example, has
