Tegundafjölbreytileiki, often translated as species diversity, refers to the variety of different species present in a particular ecosystem or region. It is a fundamental concept in ecology and conservation biology, as it reflects the health and stability of an environment. A high level of species diversity generally indicates a more resilient ecosystem, capable of withstanding environmental changes and providing a wider range of ecological services.

There are several ways to measure species diversity. Species richness is the simplest measure, counting the total number of distinct species in an area. Species evenness, on the other hand, considers the relative abundance of each species. An ecosystem with high species evenness has populations of various species that are roughly equal in size, whereas low evenness means one or a few species dominate the population.

Factors influencing species diversity include climate, habitat availability, geological history, and species interactions such as competition and predation. Human activities, such as habitat destruction, pollution, and the introduction of invasive species, can significantly reduce species diversity, leading to what is often termed a biodiversity crisis. Conservation efforts often focus on preserving and restoring habitats to maintain or increase species diversity. Understanding and monitoring species diversity is crucial for assessing the impact of environmental changes and for developing effective conservation strategies.
