Examples of species in which individuals of the same age dominate the population at any given time

In certain species, it is possible for individuals of the same age to dominate the population at any given moment. Here are a few examples:

1. Annual Plants: Annual plants complete their life cycle within a year, from germination to flowering and seed production. As a result, individuals of the same age dominate the population at any given time. Once the plants have completed their life cycle, they die, and new individuals germinate from seeds in the following year.

2. Mayflies: Mayflies are insects that have a short adult lifespan, typically ranging from a few hours to a few days. They emerge from aquatic nymphs, mate, lay eggs, and die shortly afterward. Since the lifespan of mayflies is short and synchronized, individuals of the same age dominate the population during their brief adult stage.

3. Cicadas: Cicadas are known for their periodic emergence in large numbers. Different species of cicadas have different life cycles, ranging from 2 to 17 years. During their emergence, individuals of the same age dominate the population. They mate, lay eggs, and die, starting the cycle anew.

4. Salmon: Salmon are anadromous fish that migrate from freshwater to the ocean and then return to their natal streams to spawn. They typically have a specific age at which they return to spawn, such as 3 or 4 years. During the spawning season, individuals of the same age dominate the population as they gather in large numbers to reproduce.

5. Colonial Nesting Birds: Some species of colonial nesting birds, such as certain species of herons or penguins, synchronize their breeding cycles. This means that individuals within a colony tend to lay eggs and raise their young at the same time. As a result, individuals of the same age dominate the population within the colony during the breeding season.

These are just a few examples of species in which individuals of the same age dominate the population at any given time. It is important to note that this phenomenon is not universal and varies across different species and populations.
