Key Concepts

Carrying Capacity

The concept of carrying capacity represents the maximum number of individuals an environment can sustainably support. Once the population of a surviving species approaches this limit, resource scarcity and intensified competition prevent further unchecked growth, leading to a balanced state within the ecosystem.

Ecological Opportunity

Following a mass extinction, the dramatic reduction in biodiversity opens up numerous ecological niches. This environmental shift provides surviving species with opportunities to diversify and expand into vacant or underutilized habitats, often facilitating rapid evolutionary adaptations and the formation of new species over time.

Exponential Growth

Immediately after a mass extinction event, surviving species often experience a phase of exponential growth due to the sudden abundance of resources and vacant ecological niches. This phase is characterized by rapid increases in population size, as there are fewer competitors and predators, allowing the species to reproduce at an accelerated rate.

Logistic Growth

As the population increases, growth eventually slows and stabilizes due to environmental limitations such as finite resources, space, and increased intraspecific competition. This pattern of growth is described by the logistic model, where the rate of population increase decelerates and approaches a stable equilibrium.

Genetic Bottleneck

Surviving a mass extinction often means that a species' population is reduced to a small number of individuals, which can lead to a genetic bottleneck. This reduction in genetic diversity may affect future adaptability and evolution, influencing the population's long-term growth patterns and resilience to environmental changes.
