Ydinlaji

Ydinlaji is a Finnish term that translates to "core species" or "foundation species." It refers to an organism that plays a crucial role in maintaining the structure and function of an ecosystem. The presence and abundance of a ydinlaji can significantly influence the diversity and distribution of other species within its habitat. These species are often characterized by their ability to create or modify habitats, their high biomass, or their unique ecological interactions.

The concept of ydinlaji is important in conservation biology and ecosystem management. Identifying and protecting these species is considered a priority because their decline or removal can lead to cascading negative effects throughout the ecosystem. Examples of ydinlaji can include trees that form the canopy of a forest, corals that build reefs, or beavers that create wetlands. Their impact is disproportionately large compared to their abundance or biomass.

Understanding the role of a ydinlaji helps scientists predict how ecosystems will respond to environmental changes and disturbances. Conservation efforts often focus on preserving the habitats of these keystone species to ensure the overall health and resilience of the ecological community.
