Figures 4–5. Mitochondrial D-loop 474 in Molecular confirmation of the occurrence of Anguilla interioris (Actinopterygii: Anguilliformes) in North Maluku of Indonesia and mitochondrial DNA haplotype diversity among existing specimens

Figures 4–5. Mitochondrial D-loop 474 bp sequence analyses. (4) Phylogenetic analysis based on maximum likelihood algorithm with the sample codes, GenBank accession numbers and sample sites shown. Bootstrap percentages are shown at the tree nodes. (5) Haplotype network with the haplotypes labelled as H1 to H9. The circle size is proportional to the number of samples, and different sample sites are represented by different colours. Small white circle represents median vector which is the hypothesized or missing haplotype. Each dash on the line symbolizes one mutational step.

Fig. 2. Intensity of infection (mean ± SE number of parasites per host, including infected hosts only) of the six most common helminth parasites of eels, Anguilla anguilla, in Comacchio Lagoons, during three sampling periods. Graphs on the right-hand side do not include the 2015–2017 period, as these species were not found during that period. See Table 1 for full species names.

Fig. 4. Pairwise relationships between numbers of parasites per host for the three most common digenean parasites of eels, Anguilla anguilla, in Comacchio Lagoons, across all three sampling periods combined. The line represents the relationship (with 95% confidence intervals) predicted by the generalized linear model; see text. Tick marks indicate partial residuals with either positive (top) or negative values (bottom). See Table 1 for full species names.

Fig. 1. Abundance (mean number of parasites per host, including non-infected hosts) of the six most common helminth parasites of eels, Anguilla anguilla, in Comacchio Lagoons, during three sampling periods: 2005–2006 (N = 140 eels), 2010–2013 (N = 131), and 2015–2017 (N = 30). Note that some values for the time period 2015–2017 are based on very few fish; see Table 1 for actual numbers and for full species names.
