Interspecific
Term | Definition |
---|---|
interspecific | between members of different species |
mutualistic | interspecific relationship where both species benefit from the relationship |
commensalism | interspecific relationship where one species benefits and the other is not affected |
ammensalism | interspecific relationship where one species is harmed and the other is not affected |
exploitation | interspecific relationship where one is harmed and the other benefits |
predator/prey relationship | is a form of exploitation where the prey dies and the predator benefits nutritionally |
herbivory | is a form of exploitation where the herbivore harms the plant by eating it and the herbivore benefits nutritionally. |
parasitism | is a form of exploitation where an organism lives on or in an other harming it by taking nutrients for its own gain. |
hemiparasite | a form of exploitation, but not a full parasite. Seen in mistletoe, where it gains water and some nutrients from its host plant but can photosynthesize itself. |
mimicry | An adaptation, that gains a benefit by looking like another species |
Batesian mimicry | a palatable or non-toxic species looks like an unpalatable or toxic species. |
Mullerian mimicry | Where two or more unpalatable or harmful species look similar, is a form of aposematism (warning signal), that benefits prey and predator. |
competition | interspecific relationship where both species are harmed from the relationship |
niche | the combination of an organisms, habitat, its job, the adaptations and its tolerance to abiotic factors. |
Gauses principal of competitive exclusion | no two species that have the same niche requirements can co-exist, one will always outcompete the other. |
Allelopathy (antibiosis) | interspecific relationship where one species produces a chemical that harms the other, gaining a competitive advantage |
brood parasitism | a form of exploitation, where one species lays its eggs in another species nest with the expectation the other species will raise its young. |
camouflage | a physical adaptation that makes an organism blend in with its environment |
epiphyte | a type of commensalism whereby a plant that grows on another plant gaining better access to light but is not a parasite so does not harm its host |
host | an organism that another either lives on or in |
endoparasite | a parasite that lives inside another organism |
ectoparasite | a parasite that lives on the outside another organism |
adaptation | inheritable traits that increase the chance of survival. They can be structural e.g claws, behavioural e.g. active at night or physiological, e.g. venom. |
morphology | The physical structure of an organism |
