Interactions between organisms

All living organisms interact with their environment and each other. Actually, this fact comes so easy to us, that we quite often forget about it (which is most probably the reason behind many alterations of an environment and high pollution rates). We define the interactions of organisms as competitors, predators, symbionts, and detritivores. Some scientists Read more about Interactions between organisms[…]

Coral reefs

Oh… they are just one of the most awesome and fascinating ecosystems in the world! Coral reefs are “made of” living creatures called corals that come in many different shapes and sizes. They are sessile, which means, that they need something solid to sit on while they do their thing. Usually, these cozy and solid places Read more about Coral reefs[…]

Desert ecosystems

When we see endless land, covered with sand, we immediately think: desert. But actually, this is not how all deserts look like so I feel, I should clarify what a desert ecosystem is. Deserts are… Well, the answer is not so simple. There are many factors, like precipitation, temperature, location and human activity that define Read more about Desert ecosystems[…]

Fossil fuels – what are they?

The term fossil fuels maybe isn’t the best, since they are not really made out of fossils. In this case, the word only indicates something about 650 million years old. We are talking about organisms, that sunk to the bottom of the ocean or a puddle of mud. In time, they got covered in sediment, Read more about Fossil fuels – what are they?[…]

The construction of hydropower plants

I believe I have already made myself very clear with the first two posts that we are madly in love with turbines. We install them in rivers (inside of different-shaped power plants) as well as in oceans and seas. Since these last two give us more options to choose from than the rivers, we gratefully Read more about The construction of hydropower plants[…]

Why does it matter what lives around us?

With every change we make in the environment, many ecological changes follow. We have learned, that keeping track of these changes is very important, but unfortunately, we still don’t do it as much as we should. Monitoring is very important because it gives us an overview of what’s happening in the environment. In this way, Read more about Why does it matter what lives around us?[…]

What are ecosystem engineers?

First, let me get one thing straight. This term doesn’t have the same meaning as the term keystone species, even though a keystone species usually is an ecosystem engineer. An ecosystem engineer is an organism, that has a crucial role in creating, destroying, modifying and/or maintaining habitat. With their specific behavior, they influence the availability Read more about What are ecosystem engineers?[…]

What are keystone species?

Keystone species are species, whose presence is important for maintaining the structure and therefore health and balance of the ecosystems. They play a crucial role because of their specific impact (behavior, diet etc.) on the ecosystem and are also referred to as ecosystem engineers. Keystone species are mostly predators, but they can also be herbivorous or Read more about What are keystone species?[…]
