Neozoa
<<< bioculture overview
Neozoa (invasive species) are animal species that move into new areas through human activities and establish themselves there. This can happen in a variety of ways, such as the exotic pet trade, the release of animals from captivity, or the unwanted introduction of species via ships or other means of transport. Neozoa can include both terrestrial and aquatic species.
The introduction of neozoa into new ecosystems can have far-reaching ecological and cultural consequences. On the one hand, they can threaten native species, either through direct competition for resources or through the transmission of diseases. On the other hand, they can also change human perceptions of nature and wildlife by introducing new species into landscapes that did not previously exist.
The management of invasive species therefore requires careful monitoring and management measures to minimize their impact on biodiversity and human health. This may include controlling invasive species, restoring habitats and raising public awareness of the risks and consequences of introducing neozoa.
Overall, neozoa illustrate the complex interactions between human activities, biological diversity, and cultural practices. Their occurrence and spread are closely linked to global trade and transport flows and underline the importance of an integrated and coordinated approach to the protection and conservation of ecosystems worldwide.
This list shows species ordered by the proportion of observations marked as "introduced". The data is based on observations from iNaturalist users and therefore may contain inaccurate information.
The percentage value shown implies how many observations were made outside the original distribution area.
