Eco 11 phenology & competition

phenology

Timing of seasonal life cycle (reproduction) events, determines if species will interact

fast life history means _____ trait plasticity

high

slow life history means ___ trait plasticity

low

communities are defined by

species interactions

what are intraspecific interactions

same species interactions

what are interspecific interactions

different species interacting

interference competition

direct interactions between individuals that alter their ability to attain
resources

examples of direct interactions

Food, space (territory), mates, social position, Aggressive behaviour, production of chemical toxins, reducing access to resources

Exploitative competition

individuals interact indirectly as they compete for common resources

Using resources diminishes access or availability to other individuals

examples of exploitative competition

tall trees reducing light availability to others, larger animal competing with smaller animal for resources

Biodiversity because of

niches and resource partitioning

examples of resource partitioning

using different resources,

using the same resources in different ways

whats it called when different species live together without excluding each other from the community through competition

coexistence

what does it mean for competition when niches are the same

stronger interspecific competition, competetive exclusion

what does it mean for competition when niches differ

stronger intraspecific competition, coexistence possible
