Resumo |
Size variation in the adult population of the grapsid crab Aratus pisonii (H. Milne-Edwards, 1837) was studied by comparing median values obtained from six different populations from nearby mangrove areas. The mangrove structure at those sites was also examined and related to size differences among populations. Disregarding sex, crab size is apparently related to the mangrove structure. Smallest and largest crab sizes were recorded at the sites where tree density and tree diameter were minimum and maximum, respectively. Estimates of size at the onset of maturity, considering the size of the smallest ovigerous female, followed the same trend. These results support the hypothesis that average crab size and size at the onset of maturity can be associated to mangrove productivity. |
