Morphometric analysis of Capitella capitata (Polychaeta, Capitellidae)

Abstract: ABSTRACT. Accurate size measurements are fundamental in characterizing the population structure and secondary production of a species. The purpose of this study was to determine the best morphometric parameter to estimate the size of individuals of Capitella capitata (Fabricius, 1780). The morphometric analysis was applied to individuals collected in the intertidal zones of two beaches on the northern coast of the state of São Paulo, Brazil: São Francisco and Araçá. The following measurements were taken: the w… Show more

“…Additionally, Blake (2009) indicates that C. capitata may be only distributed in Arctic regions, suggesting that the numerous records from lower latitudes are not this species. Nevertheless, the specimens from warmer waters such as in the Caribbean (Amoureux 1985) and Brazil (Pardo et al 2010) are also similar to the neotype descriptions by Blake (2009). Recently, four new species of Capitella were described from the Capitella capitata complex (Silva et al 2017).…”

“…Moreover, they do not build any protective structures such as tubes. Regarding the Capitellidae, also Pardo et al (), who worked on C . capitata , which are often numerous and dominant in soft bottom communities, stressed that most individuals of that species in their samples were fragmented.…”

“…Moreover, they do not build any protective structures such as tubes. Regarding the Capitellidae, also Pardo et al (2010), who worked on C. capitata, which are often numerous and dominant in soft bottom communities, stressed that most individuals of that species in their samples were fragmented. However, the thoracic region was almost always intact, which is why they recommended using length of chaetiger 5 or the area of chaetiger 7 as size estimators.…”

“…Neste sentido, para S. alveolata o autor selecionou o diâmetro do pedúnculo, parte abaixo da coroa opercular, e discutiu sobre esta ser uma parte do corpo resistente, cuja perda é menor no processo de dissecção dos tubos (Gruet, 1984). Ao dissecar os tubos de sabelarídeos, os exemplares podem ser facilmente rompidos, o que impossibilita medidas morfométricas em setígeros abdominais, um método comumente aplicado em outros poliquetas (PaGliosa & lana, 2000;MaCCorD & aMaral, 2005;ParDo et al, 2010;oteGui et al, 2012). Deste modo, para estudos populacionais de Phragmatopoma, este estudo viabilizou uma técnica de morfometria viável e com acuidade estatística.…”
