pollinator isolation
2 species have different pollinators (usually prevents breeding between plants)
Reproductive Isolation Mechanisms
changes that isolate one species
behavioral isolation
mating behaviors are different so they aren't attracted to each other
gametic isolation
the 2 species have incompatible sperms and eggs
temporal isolation
they don't interbreed b/c their mating periods do not overlap
ecological isolation
when 2 lineages are isolated b/c they live in separate areas
mechanical isolation
when 2 species change dramatically and the changes make it difficult or impossible for them to mate
hybrid inviability (sterility)
when sperm and egg fertilize but the offspring doesn't live
