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.
Pbmc isolation principle?
Isolating peripheral blood mononuclear cells (PBMCs) involves separating these cells from whole blood using density gradient centrifugation. The principle behind PBMC isolation is that different blood cell types have varying densities, allowing for their separation based on size and weight. By layering the blood sample over a gradient medium and spinning it at high speed, PBMCs can be collected from the interface between the plasma and the gradient medium.

Why is blood agar not useful a primary isolation medium?
Blood agar is not ideal as a primary isolation medium because it does not selectively inhibit the growth of certain bacteria, allowing for overgrowth of some microbial species. It also does not provide specific indicators for identifying different types of bacteria. Other media, such as MacConkey agar or nutrient agar, are better suited for primary isolation due to their selective and differential properties.
