Ecology

What's your favorite biomeA lot of people would say it's forests. After allthere's nothing more awe-inspiring than a sprawling oak forest filled with towering trees, fragrant pine needles, and bright green ferns. But that's not the only biomeout there! Don't forget the grassy plains, which span states from Oregon to TexasBut wait, you say, how can you be in the grassy plains when you're sitting on the ground right nowYesthose are both things I did too when I was reading this.

Why is ecology important?

Ecology enriches our world and is crucial for human wellbeing and prosperity. It provides new knowledge of the interdependence between people and nature that is vital for food production, maintaining clean air and water, and sustaining biodiversity in a changing climate.

Can we conserve a habitat and its biodiversity?

Yes. Ecology provides the essential basis for nature conservation. Maintaining a mosaic of habitats ensures the survival of a rich variety of species. For instance, heathland is a valued landscape that is fast disappearing throughout much of Western Europe, but studies have helped identify how to preserve its ecological characteristic.

Can we predict the ecological effects of pollution and climate change?

Governments and citizens around the world are increasingly aware of the consequences of atmospheric pollution and climate change. In large-scale experiments, plants and animals are exposed to carefully controlled atmospheres and different ecological conditions. Scientists use this information to understand how they respond to pollution levels, and make predictions about future climate change.

Can we fish the ocean without depleting its riches?

It is possible, but does depend on where we are in the world. In the Antarctic, the marine ecosystem is currently managed as a whole under an international agreement to conserve living resources. This makes it easier to understand marine communities and their interactions, as well as help monitor threatened species more closely.

How does forest destruction affect bird populations?

About one third of forest bird species cannot live in small remnants of forests. The smaller birds such as the forest robin will use patches as small as 10 ha and the largest species, such as the brown-cheeked hornbill, need patches bigger than 10 square km. Forests across the world today continue to be cleared and converted into different land uses. For example, by 2005, over 80% of the high-forest in Ghana had been cleared in just 100 years. Fortunately, researchers have used ecological studies to advise on the effects land-conversion has on native species.
