Not all ecosystems are equal when it comes to biodiversity. Some contain just a few hardy species, while others teem with thousands of plants, animals, fungi, and microorganisms. But what exactly describes an ecosystem with high biodiversity? The answer lies in three main traits: species richness, genetic variation, and ecosystem complexity. Defining High Biodiversity An

Biodiversity is under pressure from many directions: climate change, invasive species, overexploitation, and pollution. But scientists agree that one factor stands above the rest as the single greatest threat to biodiversity: habitat loss and fragmentation caused by human activity. In this post, we’ll explain why habitat destruction is so dangerous, how it interacts with other

Not all places on Earth hold the same level of biodiversity. Some regions are especially rich in species, many of which are found nowhere else. These areas are known as biodiversity hotspots. But what makes them so important, and why should we focus global conservation efforts on protecting them? What Is a Biodiversity Hotspot? A

When Charles Darwin set out on the voyage of the HMS Beagle (1831–1836), he made observations that would change biology forever. His studies of plants, animals, and fossils across South America and the Galápagos Islands revealed clear patterns of biodiversity—clues that eventually led to his theory of evolution by natural selection. Darwin observed three major

Biodiversity is not spread evenly across the planet. Some ecosystems are sparse, supporting only a few species, while others are bursting with life. But which ecosystem has the highest biodiversity on Earth? The answer: tropical rainforests on land, and coral reefs in the ocean. What Is an Ecosystem? An ecosystem is a community of living

Biodiversity isn’t just a concept—it can be measured. Ecologists use mathematical formulas and indices to calculate biodiversity, helping them understand the health, richness, and stability of ecosystems. In this guide, we’ll explain how biodiversity is calculated, the most common methods, and why these measurements matter for conservation and research. What Does Measuring Biodiversity Mean? Biodiversity

While some ecosystems like tropical rainforests and coral reefs teem with life, others support only a small number of highly specialized species. But which biome has the lowest biodiversity? The answer: the tundra biome. What Is the Tundra Biome? The tundra is a cold, treeless biome found in the Arctic and at high mountain elevations
