30 gru 2021 · Seed dispersal by wind has the advantage that it allows seeds to be transported far away from the parent plant, thus reducing their growth competing. On the other hand, the primary constraint on wind dispersal is the need for abundant seed production to increase germination as much seed gets wasted using transfer.
Seed Ejection: Certain plants have structures that actively eject seeds, increasing the chances of wind dispersal. Seed Dislodgement: Other plants have seeds that are easily dislodged from their parent plant by wind or physical disturbances.
16 lut 2011 · Dispersal occurs when seeds move away from the source plant. The length of this movement, the dispersal distance D, is the measure of the dispersal process, and the distribution of dispersal distances, the seed dispersal kernel p (x), is its basic statistical descriptor.
17 maj 2014 · Long-distance dispersal (LDD) of plant seeds by wind is affected by functional traits of the species, specifically seed terminal velocity and height of seed release above the vegetation cover (HAC), as well as by the meteorological parameters wind speed and vertical turbulence.
We compiled a comprehensive dataset of seed dispersal distance classes and predominant dispersal modes for most European vascular plants. Our seed dispersal dataset can be used in functional biogeography, dynamic vegetation modelling and ecological studies at local to continental scales. Main Types of Variables Contained
6 sie 2015 · Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources. Other seeds are dispersed by the wind—such as the "winged" seeds from a...
11 paź 2024 · In the modern world, wind dispersal (although numerically important) reflects the climatic and biotic poverty of certain regions; it is essentially a feature of pioneer vegetations. The flora of the Alps is 60 percent anemochorous; that of the Mediterranean garrigue (a scrubland region) is 50 percent.
