Academic Paper

Two species of Centrobolus were identified (C. anulatus, C. inscriptus) based on morphology and confirmed using Scanning Electron Microscopy (SEM) of the gonopod structure. Two sets of linear measurements were made: (1) size, and (2) absolute abundance. Male and female sizes in two species were gaged. Male size and absolute abundance were positively related (r=0.63, Z score=1.66, n=8, p<0.05). Female size and absolute abundances were related (r=0.63046242, Z score=1.65957221, n=8, p=0.04850025). Male and female lengths were correlated with absolute abundances (r=-0.50192206, Z score=-1.98980348, n=16, p=0.02330622). Male length was related to abundance (r=-0.63046242, Z score=-1.65957221, n=8, p=0.04850025). Female length was related to abundance (r=-0.63046242, Z score=-1.65957221, n=8, p=0.04850025). Male and female widths were correlated with absolute abundances (r=0.443547, Z score=1.71854248, n=16, p=0.04284882). Male width was related to abundance (r=0.63046242, Z score=1.65957221, n=8, p=0.04850025). Female width was related to abundance (r=0.63046242, Z score=1.65957221, n=8, p=0.04850025). Sexual Size Dimorphism (SSD) was related to abundance (r=0.63, Z score=1.66, n=8, p<0.05).
