Population and Community Ecology

In the study of population and community ecology, one delves into the mechanisms behind population growth, regulation, and organisation. Additionally, this field scrutinises the complex network of interactions such as predation, competition, and symbiosis that characterise communities. An understanding of succession and stability sheds light on the dynamic processes through which ecosystems change over time.

Populations, defined by their size and density, are influenced by birth rates, death rates, immigration, and emigration. The balance of these factors determines whether a population grows, declines, or maintains stability. Ecologists utilise models like the logistic growth model to predict population dynamics, incorporating the concept of carrying capacity, which is the maximum population size an environment can sustain.

Community ecology examines the relationships between species within an ecosystem. These relationships can be competitive, where species vie for the same resources, or mutualistic, where species benefit from their interactions with one another. Predation and herbivory are interactions where one organism feeds on another, significantly impacting population sizes and community structure.

Succession, the orderly process of community development over time, occurs in two types: primary and secondary. Primary succession begins in lifeless areas, such as those left by retreating glaciers, where soil hasn't yet formed. Secondary succession takes place in areas where a community has been disturbed but soil remains, such as after a forest fire. These successional stages lead to changes in species composition and community structure until a relatively stable ecosystem, known as the climax community, is established.

Ecosystem stability, a measure of an ecosystem's ability to return to a particular state after a disturbance, is crucial for sustaining biodiversity. Factors contributing to stability include species diversity, which can buffer against environmental changes, and the presence of keystone species, which play a critical role in maintaining the structure of a community.
