AI Article Synopsis
- This study evaluated the ecological health of waters in the Saudi Arabian Exclusive Economic Zone using benthic biotic indices from 2013 to 2018, covering 67 sampling locations with various depths and salinity.
- Researchers found variations in macrobenthic density, averaging 566 individuals per square meter, and measured biodiversity with a Shannon diversity index averaging 4.70.
- Most locations were deemed slightly disturbed or undisturbed, with 95.5% of sites showing good or high ecological status according to the M-AMBI analysis.
Article Abstract
This study assessed the ecological health of waters within the Saudi Arabian Exclusive Economic Zone, by utilizing benthic biotic indices with a marine monitoring dataset covering the years 2013 to 2018. This comprehensive evaluation covered a vast expanse, encompassing 67 distinctive sampling locations characterized by a wide range of depth and salinity gradients. The study examined spatial fluctuations in the benthic community and assessed potential correlations with environmental variables, including salinity, depth, sediment texture, total organic carbon, and other relevant factors. The macrobenthic density varied across the study sites, with an average density of 566 ± 120 ind.m. The Shannon diversity index ranged from 3.21 and 5.90, with an average of 4.70 ± 0.52. Based on the average AMBI values, all the locations were categorized as either slightly disturbed or undisturbed. Additionally, the M-AMBI analysis indicated that 95.5 % sites were in good or high ecological status.
