lajimäärät

Lajimäärät, or species richness, refers to the total number of different species present in a given area or ecosystem. It is a key indicator of biodiversity and ecosystem health. High species richness is often associated with stable and diverse ecosystems, while low species richness can indicate environmental stress or degradation.

Species richness can be influenced by various factors, including habitat availability, climate, and human activities. For example, areas with diverse habitats, such as forests with different vegetation types, tend to have higher species richness. Similarly, climate can affect species richness by determining the types of species that can survive in a particular area.

Human activities, such as deforestation, pollution, and climate change, can significantly impact species richness. Deforestation, for instance, can lead to habitat loss and fragmentation, reducing the number of species that can inhabit an area. Pollution can also harm species by contaminating their habitats or directly affecting their health.

Conservation efforts aim to protect and restore species richness by preserving habitats, reducing pollution, and mitigating the impacts of climate change. These efforts are crucial for maintaining the health and resilience of ecosystems and ensuring the survival of the diverse array of species that inhabit them.
