Impact of Halamphora lombokensis on Kuta Beach Marine Ecosystem

The introduction of Halamphora lombokensis, a newly identified marine diatom species, has significant implications for the local marine ecosystem at Kuta Beach, Lombok, Indonesia. This species thrives in highly saline sandy environments, characterized by specific physicochemical conditions such as high temperature (33.3 °C), salinity (32 ppt), and dissolved oxygen levels (18.5 mg/L) .

Ecological Role

As a primary producer, H. lombokensis plays a crucial role in the marine food web. Diatoms are known for their ability to perform photosynthesis, thus contributing to the primary production of organic matter, which serves as food for various marine organisms, including zooplankton and small fish. The presence of this diatom species can enhance the overall productivity of the ecosystem, supporting higher trophic levels.

Biodiversity and Species Interactions

The introduction of H. lombokensis may also influence the biodiversity of the area. Its morphological characteristics, such as valve length (11.0-13.0 µm) and width (2.0-3.0 µm) with a striae density of 28-32, allow it to coexist with other diatom species, potentially leading to increased competition for resources Citation on ecological preferences.

Potential Challenges

While the introduction of H. lombokensis can enhance biodiversity, it may also pose challenges. The reliance on morphological characteristics for species identification may overlook genetic diversity, leading to potential misidentifications and ecological imbalances. Furthermore, the geographic scope of the study is limited to Kuta Beach, which may not represent the broader ecological dynamics of diatom populations across Indonesia.

Conclusion

In summary, the introduction of Halamphora lombokensis at Kuta Beach is likely to enhance local biodiversity and contribute positively to nutrient cycling within the marine ecosystem. However, ongoing monitoring and research are essential to fully understand its ecological impact and interactions with other species.
