How Does an Increase in Biodiversity Lead to an Increase in Ecosystem Stability

How does an increase in biodiversity lead to an increase in ecosystem stability? The answer is that it has a moderating effect on the environment. When there are more different organisms, they balance each other out and keep the system stable. A lack of biodiversity leads to instability because one species can’t compensate for another when something goes wrong. For example, if every animal relied on plants for food, then a shortage of plant life would cause all animals to die off too!

Biodiversity is a measure of the variety of species found in an ecosystem, and a greater biodiversity typically means a more stable ecosystem. The opposite is also true: decreasing biodiversity has resulted in less stability for ecosystems. Ecosystems with lower levels of biodiversity are more likely to be susceptible to harmful influences like invasive species or changes in climate.

The introduction above was written by Nicole Gaffney, an undergraduate student at UC Berkeley studying Ecology and Evolutionary Biology with interests in conservation biology and animal behavior research.

In recent years there has been much focus on the health of our planet’s environment as we learn about how human activity affects it; this includes everything from pollution to habitat destruction to global warming. One aspect of this health sometimes overlooked in conservation research is biodiversity.

The relationship between biodiversity and ecosystem stability is one that has been studied extensively by scientists. One study found that a 10% increase in the number of species within an environment led to a 4% increase in ecosystem stability. This means that when you have more diverse ecosystems, they are less likely to be disrupted or experience abrupt change. In fact, this trend was true across all four biomes (temperate deciduous forest, temperate coniferous forest, tropical evergreen forest and desert). What does this mean for us? It seems like having more biodiversity can lead to greater stability for our own environments!

The more different species in an ecosystem, the more resilient it is to change. To illustrate this point, we’ll use a hypothetical example. Imagine that there are two ecosystems – one with 20 species and another with only 10 – both of which have 100 units of biomass available for consumption. If a single species from each system were removed, the remaining 90 units would be enough food for all 10 animals left in the second system but not enough food for 30 animals in the first system (assuming they eat equal amounts).┬áIn other words, removing just one animal from a diverse environment leaves fewer animals alive than if you remove an animal from an environment where there are few types of plants or wildlife present. So while some people may think biodiversity means many different kinds of things, those different kinds of things have a direct impact on how well an ecosystem can withstand changes.

It is safe to say that biodiversity – the variety and number of species in an environment – leads to more stability in an ecosystem as opposed to when there are few types of plants or wildlife present. One way this happens is illustrated by our hypothetical example: if one animal from each system were removed, the remaining 90 units would be enough food for all ten animals left in the second system but not enough food for thirty animals in the first system (assuming they eat equal amounts). In other words, removing just one animal from a diverse environment leaves fewer animals alive than if you remove an animal from an environment where there are few types both plants and animals.

The second reason that an increase in biodiversity leads to more stability is because it gives animals a wider range of food sources and mates, which helps them reproduce at higher rates than if they’re only eating one type of tree or are limited to mating with the same types of animals as themselves. For example, when there’s less variety in plants, birds have fewer seeds from which to feed their chicks; whereas when different species of trees exist side-by-side on a forest floor (or lots), these small birds have plenty to eat for their young. The other benefit is that this diversity also makes each animal healthier: some prey may not be susceptible enough to certain diseases without being present alongside others who are immune – so an environmental change that might only affect one species could be deadly to another.

A major reason why biodiversity has a stabilizing effect on an ecosystem is because it gives animals a wider range of food sources and mates, which helps them reproduce at higher rates than if they’re only eating one type of tree or are limited to mating with the same types of animals as themselves. For example, when there’s less variety in plants, birds have fewer seeds from which to feed their chicks; whereas when different species of trees exist side-by-side on a forest floor (or lots), these small birds have plenty to eat for their young. The other benefit is that this diversity also makes each animal healthier: some prey may not be susceptible enough to certain diseases without being exposed to other species, while others may not be able to evolve and adapt as quickly.
