Capillary refill time
Explanation:
Capillary refill time refers to the time that it takes for color to return to an external capillary bed after pressure has been applied (which causes blanching). Usually, on healthy individuals, capillary refill time takes less than 2 seconds. If the time is much longer, this could indicate problems such as shock, dehydration or peripheral artery disease.

Gene flow
Explanation:
Gene flow describes the process where genetic information migrates to another population, introducing new alleles into the gene pool and increasing the variation in that population.
Having physical barriers would prevent this exchange of information. For example, two populations separated by a mountain range or body of water would have far less chances to interact and exchange genetic material. This would make it difficult for gene flow to occur.
