Dispersion characteristics of radioactive materials estimated by …
Jul 2, 2018 · Here, we show that dispersion directions, which are divided into four ranges, can be estimated by wind patterns using a machine learning approach.
Mechanisms of long-distance dispersal of seeds by wind
Jul 25, 2002 · Many common and economically important tree species, especially those of temperate and boreal forests, have morphological adaptations that facilitate dispersal by wind …
Putting wind dispersal in context - Nature Climate Change
Jul 20, 2020 · Any long-distance wind dispersal event is dependent on three critical steps: ejection above the vegetation canopy, long-distance movement and deposition in a suitable habitat.
plant canopy can reduce diaspore dispersal distance, which is controlled by diaspore traits and wind speed. To test our hypothesis, controlled experiments were conducted in a wind tunnel, …
Wind velocity and dispersion/advection–diffusion of ... - Nature
Nov 4, 2024 · To evaluate the COVID-19 infection risk and the effectiveness of countermeasures at mass-gathering events, we measured the dispersion and advective diffusion of artificial …
Global wind patterns and the vulnerability of wind-dispersed
Jul 20, 2020 · Wind patterns could enhance or hinder the ability of organisms reliant on wind-driven dispersal and pollination to shift their ranges under climate change.
Micro-scale modelling of the urban wind speed for air pollution ...
Oct 3, 2019 · Modelling wind speeds in urban areas have many applications e.g. in relation to assessment of wind energy, modelling air pollution, and building design and engineering.
A separated vortex ring underlies the flight of the dandelion
Oct 17, 2018 · This passive flight mechanism is highly effective, enabling seed dispersal over formidable distances3,4; however, the physics underpinning pappus-mediated flight remains …
Plant canopy may promote seed dispersal by wind
Jan 7, 2022 · Increased dispersal distance may due to induction of an updraft by wind hitting the plant canopy or by change in direction of diaspores that collide with a plant part can change …
Response and sensitivity of urban plants with different seed …
Dec 11, 2024 · Adaptations representing wind dispersal include dust-like seeds (for example, the small and lightweight seeds, such as most of species in Asteraceae family), balloon-like …
