- What do you think would happen to the population of blue whales after hunting them was banned? A. There was a substantial increase in whale numbers. B. There was a slight decrease in population numbers. C. There was no effect.Biology Practice #2 Question Changes in the Florida Panther Population Florida panthers are a subspecies of cougars that live in the wetlands and forests of southern Florida. They are strict carnivores. Their diet consists mostly of deer, wild hogs, and livestock. Florida panthers need a large habitat in order to successfully hunt, reproduce, and raise their young. During the last century, the Florida panther population has experienced habitat fragmentation due to the construction of roads, urbanization, mining, and agriculture. This fragmentation has led to an increase in inbreeding within their population. Inbreeding occurs when closely-related animals mate and produce offspring. Inbred animals have a higher risk of inheriting genetic diseases, which often reduces their survival or ability to reproduce. 1995 Population size = 26 To conserve the population of Florida panthers, a team of scientists introduced eight Texas panthers to Florida in 1996. Texas panthers are a closely related…Which factor is not responsible for the large increase in the human population over the last 300 or so years?a.
