Final answer:
Koening and Knops analyzed masting, the simultaneous production of seeds by plants, and its ecological impact, which is related to the invasion biology of species such as the Pacific Oyster in Scandinavian waters.
Step-by-step explanation:
Koening and Knops discussed the phenomenon of masting, which is a term used to describe the synchronous production of seed crops by populations of perennial plants. This occurrence can vary in frequency and intensity, and has significant effects on surrounding ecosystems. Although Koening and Knops themselves are not directly mentioned in the reference provided, masting is relevant in the context of invasion biology, particularly looking at organisms such as the Pacific Oyster (Crassostrea gigas).
In the context of the Pacific Oyster invasion in Scandinavian coastal waters, masting can influence the availability of resources for native species and the competitive interactions within the ecosystem. This can ultimately impact local ecosystem services, resulting in ecological shifts and changes in biodiversity.
