Epidemiologists would study the causes of a present-day epidemic. They investigate the patterns and causes of diseases in populations to help prevent and control outbreaks.
No, declines are not facts
The octopus and shark populations will decline.
Temporal isolation between populations is caused by differences in the timing of reproductive activities, such as mating seasons or times of day when individuals are most active. This can prevent individuals from different populations from mating and producing offspring, leading to reproductive isolation.
Global Warming
Because the liver help break down fat and because the liver is now covered in fat it causes dysfunction with the liver. i dunno just guessing.
genetic variation
European explorers and settlers brought diseases such as smallpox to America and the Native peoples did not have an immunity to them and it dramatically reduced their populations.
Rapid and extreme environmental changes are most difficult for organisms to adjust to because they can disrupt the balance of ecosystems and outpace an organism's ability to adapt through natural selection. These changes can lead to extinction events or severe declines in populations.
