Figure 1. Area of eDNA and UVC surveys along the southern coast
of Curaçao. The main sampling areas were the coastal stretch of
Valentijnsbaai in the more remote northern part of the island and the
coastal stretch along the main city of Willemstad in proximity to
industrial and other anthropogenic activities.
Figure 2. Spider plots of indices, richness accumulation curves
and boxplot of beta diversity showing the comparison between both the
Willemstad (purple) and Valentijnsbaai (green) sampling sites. The first
column (a) shows the community-level weighted means of trait values (TL:
Trophic Level; BS: Body Size), the taxa richness accumulation curves and
the taxonomic 𝛽 dissimilarity. The second column (b) shows the main
functional diversity indicators (FRic: functional richness; Fdiv:
functional divergence; Fori: functional originality; Fspe: functional
specialisation; TR: taxa richness), the functional richness accumulation
curves and the functional 𝛽 dissimilarity. The third column (c) shows
the main phylogenetic indicators (PD: phylogenetic diversity; MPD: Mean
Pairwise Distance; VPD: Variance of the Pairwise Distance ;MNTD: Mean
Nearest Taxonomic Distance; VNTD: Variance of the Nearest Taxonomic
Distance), the phylogenetic richness accumulation curves and the
phylogenetic dissimilarity.
Figure 3. Compositional differences (PCoA) (a) from the
presence absence matrix between the eDNA samples (b) and from the UVC
transects between both the Willemstad (purple) and Valentijnsbaai
(green) areas. The maps indicate the geographic positions of the samples
with the corresponding colours.
Figure 4. Individual species responses to the coastal area,
where positive coefficient indicate greater signal of occupancy in
Valentijnsbaai compared with Willemstadt. Upper panels related to
species responses revealed through eDNA metabarcoding (a), whereas lower
panels indicate species responses revealed through UVC transects (b).
Uncertainty in the estimated species parameters with eDNA, UVC with the
same number of samples as eDNA and UVC with all samples is provided (c).
