speciation...or not!

select the barrier: crickets of a similar species live in sandy areas and others (similar species) live in grassy areas

• habitat isolation

• mechanical isolation

• temporal isolation

• gametic isolation

• behavioral isolation

select the barrier: similar species of flowers are structured differently - one suits bees and another suits hummingbirds

• habitat isolation

• mechanical isolation

• temporal isolation

• gametic isolation

• behavioral isolation

select the barrier: similar species of owl mate at different times of the day

• mechanical isolation

• temporal isolation

• gametic isolation

• habitat isolation

• behavioral isolation

select the barrier: the males of similar fish species release their eggs in water, but fertilization is only successful when the sperm and egg are of the same species

• temporal isolation

• gametic isolation

• behavioral isolation

• mechanical isolation

• habitat isolation

select the barrier: swamp sparrows and song sparrows have similar mating calls, but they don't respond to each other's call

• behavioral isolation

• mechanical isolation

• gametic isolation

• temporal isolation

• habitat isolation
