Question

1. tradescantia ohiensis, a plant also known as bluejacket and its relative, t. subaspera have similar reproductive mechanisms but do not mate, as one species lives in sun while the other lives in shade

a. geographic isolation b. behavioral isolation c. temporal isolation

1. a type of isolation in which two populations with complex courtship displays or rituals become different enough that they no longer respond to the others actions.

a. geographic isolation b. behavioral isolation c. temporal isolation

1. the american toad (anaxyrus americanus) and fowlers toad (bufo fowleri) live in the same area. however, the american toad mates in early summer while fowlers mates in late summer.

a. geographic isolation b. behavioral isolation c. temporal isolation

1. the flashing pattern of the firefly (lampyridae) is used to attract the opposite sex. female fireflies only flash back and attract male fireflies who first signal them with a species - specific pattern of light

a. geographic isolation b. behavioral isolation c. temporal isolation

1. a type of isolation where two species whose ranges overlap have different periods of sexual activity or breeding seasons.

a. geographic isolation b. behavioral isolation c. temporal isolation

1. alberts squirrel and the kaibab squirrel are distinct subspecies that live on opposite sides of the grand canyon. they were once one species, but now differ significantly, including fur coloring.

a. geographic isolation b. behavioral isolation c. temporal isolation

1. of the seven species of cicada, (cicadae), three follow a 17 - year mating cycle, while four follow a 13 - year cycle. in regions where their geographic range overlaps, their emergence coincides once in every 221 years. this last happened in north america in 2015 and will not occur again until the year 2236.

a. geographic isolation b. behavioral isolation c. temporal isolation

Explanation:

• Question 4: The plants live in sun and shade respectively, which is due to habitat - related geographical differences, so it's geographic isolation.
• Question 5: Different courtship displays mean behavioral differences causing isolation, so it's behavioral isolation.
• Question 6: Different mating times (early and late summer) indicate temporal isolation.
• Question 7: Species - specific light - flashing patterns for courtship are behavioral traits, so it's behavioral isolation.
• Question 8: Different breeding seasons or sexual activity periods mean temporal isolation.
• Question 9: Living on opposite sides of the Grand Canyon is a geographical factor causing isolation, so it's geographic isolation.
• Question 10: Different mating cycles and rare coincidences of emergence are related to time, so it's temporal isolation.
