Symposium Introduction
Neutral attitude.
Neutralism - form relationships in which inhabit the same territory
organisms do not affect each other. When neutralism individuals of different species are not
relate to each other directly, but by forming biocenose depend on
of the community as a whole. For example, squirrels and moose, upholstered in the same forest, not
contact with each other, but the state of the forest affects each of
these species.
When amensalizme for one of the two interacting species effects
co-habitation are negative, while the other of them do not receive any
harm or benefit that is more common in plants (eg, light-loving
herbaceous species growing under spruce, experiencing depression as a result of
shading, whereas the proximity of the tree could be indifferent).
All these forms of biological relationships between species are registrars
number of animals and plants in biocoenosis, determining the extent of its
sustainability, while more species composition of the biological community, the more stable
community as a whole .
