What is generalist species?

A generalist species is an organism that has a broad ecological niche and can tolerate a wide range of environmental conditions. Generalist species are often able to exploit a variety of resources and occupy different habitats, making them well-suited to a variety of ecological settings. This broad adaptability allows generalist species to outcompete specialist species in many cases, but in some cases, the high specialisation of a specialist species may become its competitive advantage.

Common examples of generalist species include:

- Humans: Humans are able to adapt to a wide range of climates, terrain, and diets. They are able to use tools and technology to survive in different environments.

- Rats: Rats are able to live in a variety of habitats, from urban areas to forests. They are able to eat a wide variety of foods and reproduce rapidly.

- Pigeons: Pigeons are able to live in cities, suburbs, and rural areas. They are able to eat a variety of foods and build nests in a variety of locations.

Many generalist species have human influences associated with their successful colonisation of new areas. For example, rats have achieved significant populations throughout the world owing to human trade, and pigeons are now commonly found on every continent except Antarctica, even including remote archipelagos.
