This allows scientists to observe the difference between population variation, climate and well as the size and shape of the landscape. An example of the use of landscape genetics as a means to study seed dispersal, for example, involves studying the effects of traffic using motorway tunnels between inner cities and suburban area.
Epilobium hirsutum seed head dispersing seeds. In spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. [1] Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living vectors such as birds.
Dispersion in biology is the dissemination, or scattering, of organisms over periods within a given area or over the Earth. The dispersion of species into new locations can be inspired by many causes. Often times species naturally disperse due to physiological adaptations which allows for a higher survival rate of progeny in new ecosystems.
In other cases, the virus can cause systemic disease through a disseminated infection spread throughout the body. The predominant mode of viral dissemination occurs through the blood or lymphatic system, some of which include viruses responsible for chickenpox (varicella zoster virus), smallpox , HIV (human immunodeficiency virus). A minority ...
These seeds are metaphors for voice or words: to spread voice, words, and opinion to an audience. In a scientific context, dissemination is defined as making projects results available to the scientific community, policy makers and industry – using scientific language prioritizing accuracy. [1]
A species range map represents the region where individuals of a species can be found. This is a range map of Juniperus communis, the common juniper.. Species distribution, or species dispersion, [1] is the manner in which a biological taxon is spatially arranged. [2]
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Some infrequent or exceptional events influence the dissemination of airborne diseases, including tropical storms, hurricanes, typhoons, or monsoons. [35] Climate affects temperature, winds and relative humidity, the main factors affecting the spread, duration and infectiousness of droplets containing infectious particles. [25]
