Front
the competition coefficient describing the effect on species 1 of species 2 would is written as α12 while the competition coefficient describing the effect on species 2 of species 1 would be written as α21.
Back
allelopathy
Front
The production of chemicals by plants that inhibit the growth of neighbouring plants

Back
competition

Back
interference competition
Front
Interference competition occurs when competing individuals (usually of the same species) directly interact in an attempt to reduce the other's access to resources
Back
realized niche
Front
the range of abiotic and biotic conditions under which a species actually lives
Back
interspecfic competition
Front
Interspecific competition occurs when individuals of one species limit the resources available to another species.
