üleminekualad

Üleminekualad, often translated as transition zones or ecotones, are areas where two or more distinct ecosystems or habitats meet and merge. These zones are characterized by a gradual change in environmental conditions, such as soil type, moisture levels, temperature, and light exposure, as one ecosystem gives way to another. Examples include the area where a forest meets a grassland, a riverbank transitioning into the adjacent terrestrial environment, or the boundary between a coral reef and the open ocean.

The biodiversity within üleminekualad is often higher than in the adjacent, more uniform ecosystems. This is because they can support species from both bordering habitats, as well as unique species that are specifically adapted to the conditions found in the transition zone itself. These unique species may have a wider range of ecological niches available to them. The species composition can be a mix, and in some cases, species from one ecosystem may extend their range into the other through the transition area.

Üleminekualad play a crucial role in ecological processes. They can act as corridors for species movement, facilitating gene flow and migration between different populations. They also contribute to ecosystem resilience by providing a buffer against environmental changes. For example, a wetland transitioning into a forest might help mitigate the impact of floods. However, üleminekualad are often sensitive to disturbances and human activities, such as habitat fragmentation and pollution, which can degrade their ecological integrity and reduce their biodiversity. Conservation efforts often focus on protecting these valuable transitional zones.
