Fauna of South America
In the article we present today, we want to delve into the world of Fauna of South America, a topic that has aroused the interest of society in recent years. Fauna of South America is a concept that covers various aspects, from history to the present, including its implications in different areas. Throughout this article, we will explore the different perspectives that exist around Fauna of South America, as well as its evolution over time. We will delve into its origins, explore its relevance in today's society and analyze its impact in different contexts. Without a doubt, Fauna of South America is a fascinating topic that deserves to be addressed in detail, and we hope that this article contributes to enriching the understanding of it.
The fauna of South America consists of a huge variety of unique animals some of which evolved in relative isolation. The isolation of South America allowed for many separate animal lineages to evolve, creating a lot of originality when it comes to South American animal species.[1] The isolation of South America had an abrupt end some few million years ago when the Isthmus of Panama was formed, allowing small scale migration of animals that would result in the Great American Interchange which caused many marsupials such as Thylacosmilus to go extinct.[2] South America is the continent with the largest number of recorded bird species.[3]
Additionally, speciation has occurred at a higher rate in South America than in other parts of the world.[1] This is likely due to the large amount of land mass close to the equator. The amount of speciation at the equator compared to the rest of the world is much greater.[4]
Types of fauna
- Freshwater fish: 2,700 species[1]
- Birds: 3,000 species[1]
- Mammals
- Arthropods
- Amphibians and reptiles
- Tree frogs are one of the most abundant[1]
