Usage

The term "sympatric" is used primarily in the fields of biology, ecology, and evolutionary science. It describes populations, species, or a mode of speciation (the formation of new species) that happen in the same geographic region.

Examples

• Two sympatric species of finch may compete for the same seeds on an island.
• The study investigated whether the two frog populations were truly sympatric or if they occupied different microhabitats.
• Sympatric speciation is a theoretical process where new species evolve from a single ancestral species while inhabiting the same geographic region.

Advanced Usage

• Sympatry (n.): The state or condition of being sympatric. This is the noun form.
  • The sympatry of the two lizard species led to intense competition.
• The concept is often contrasted with allopatric (occurring in separate, non-overlapping geographic areas).

Variants and Related Words
