Ecosystems

Also known as old-growth forests, primary forests are those which are made up of native tree species which have had a minimal amount of human intervention. With such little interference in their growth and development, primary forests are those which have ecological processes which have remained largely...

An ecoregion is an area of the planet which is defined by both its ecology and geography in terms of natural ecosystems and size. Earth is rich in biodiversity, but different parts of Earth have very different ecological characteristics. How we understand such biodiversity requires categorization. Doing...

A thorn forest, also known as a thorn scrub or thorn forest, is a biome characterized by the presence of trees and shrubs with sharp, pointed thorns or spines. This habitat is found in regions with arid or semi-arid climates, typically in areas with low rainfall and high temperatures. Thorn forests are...

Steppes are a type of biome or terrestrial ecosystem. They are characterized by low levels of vegetation, low rainfall and an arid continental climate. Despite their name, steppe biomes are not defined by their altitude. There are steppes at both high and low elevations. They are wide plains which can...

Wetlands are areas of land that are either permanently or seasonally saturated with water. They are found throughout the world and include a variety of habitats such as marshes, swamps, and bogs. Wetlands are important ecosystems that provide numerous benefits to both humans and wildlife. Wetlands also...

A body of water refers to various large accumulations of water which can be either natural or manmade. This means they can range from just a few feet to millions of square miles of surface area. Size is not the only defining characteristic of bodies of water. How the water flows within it, how water...

Located near coastal regions of various oceans, we can find the presence of underwater kelp forests. Although they can seem like magical spaces more closely associated with fairy tales than science, they are naturally occurring underwater forests. Unlike their terrestrial counterparts, underwater kelp forests...

The world's rainforests store up to 50% of the CO2 that exists in our atmosphere, although this amount may be reduced thanks to climate change. The ability to absorb so much carbon dioxide is thanks to the vegetation which abounds in jungle ecosystems. It is thanks to this abundant vegetation that we can...

Although all ice is frozen water, we categorize this substance in different ways according to certain categorizations. It is for this reason we can know the difference between an ice cube and an iceberg. These characteristics are important as they have various repercussions on Earth's climate, something...

Water is one of the most important elements on our planet and necessary for the existence of life. Without it, all living things and plants would die out. Oceans and rivers feed us, regulate our climate, and produce much of the oxygen we breathe. They are also the basis for much of the global economy,...

You may be aware of wetlands. It may also be fairly easy to deduce that a wetland is a piece of land with a high water content, but then it is easy to be unsure how to differentiate this between geographical features such as lakes and swamps. For this reason, understanding the terminologies of different...

The Andes are one of the world's most beautiful mountain ranges, extending from Venezuela in the north all the way through to Argentina in the south. In fact, they are the largest continental mountain range in the world. Covering such a large span of territory, it is understandable that the area around...

Ecology is the study of ecosystems and the various biological, zoological, botanic and environmental processes which construct these ecosystems. One definition of ecosystems states they are formed by natural environments called biotopes and by a community of living beings called biocenosis. These can be...

Biodiversity reaches higher rates in tropical biomes than in polar biomes. We know this thanks to studies of the world's ecosystems. Ecologists have been able to confirm the fact that greater diversity in nature occurs closer to the equator by obtaining exact data on the flora and fauna of each biome on...

The enormous natural splendor of our planet is still being discovered, despite our best attempts to chart every last inch of the globe. In an attempt to understand how it works, cartographers, researchers and various scientists have had to rely on a range of categorizations. This includes to myriad species...

Lakes, lagoons, rivers, ponds, seas or oceans are all types of bodies of water. Some are much bigger than others, but size is not the only difference between them. Since so many of the world's bodies of water and waterways are so interconnected, it can sometimes be difficult to tell the difference between one...

Temperate forest biomes are very diverse, as we can distinguish between different types, such as temperate deciduous forests, temperate rainforests, temperate coniferous forests, temperate deciduous forests, or mixed temperate forests, to name a few. These forests, as their name implies, are located in the temperate...

Inland waters are permanent bodies of fresh water lying on or below the surface of the earth. Except for estuaries and other watercourses, these waters are distant from coastal areas. They are areas whose characteristics and uses are characterized by permanent, seasonal, or intermittent flooding. These waters...

Our planet has many terrestrial biomes home to a large number of ecosystems with spectacular biodiversity. Forests are one such biome, distinguished by the presence of a large amount of trees. Despite there being certain criteria which make a forest a forest, there are many different types which can seem almost...

We may be aware of the basic concept of an ecosystem, but it is easy to become overwhelmed once we start to look a little closer. The diversity and complexity of the world's ecosystems are only limited by space since every square millimeter of our planet is part of some larger ecosystem. Understanding how...
