<speciesfyi-glossary slug="sympatric"></speciesfyi-glossary>Definition
Describing populations or species that occupy the same geographic area and can potentially interact.
Detailed Explanation
Sympatric species must partition resources or exploit different niches to coexist — character displacement drives divergence in traits like bill size or feeding time when species overlap. Hybrid zones arise where sympatric species' ranges overlap and interbreeding occurs. Competitive exclusion can occur in sympatry if niches overlap too much. Invasive species meeting natives in sympatry — without a shared evolutionary history — often outcompete them.
