Morphometric and molecular identification of individual barnacle cyprids from wild plankton: an approach to detecting fouling and invasive barnacle species

Abstract: The present study used DNA barcodes to identify individual cyprids to species. This enables accurate quantification of larvae of potential fouling species in the plankton. In addition, it explains the settlement patterns of barnacles and serves as an early warning system of unwanted immigrant species. Sequences from a total of 540 individual cypris larvae from Taiwanese waters formed 36 monophyletic clades (species) in a phylogenetic tree. Of these clades, 26 were identified to species, but 10 unknown monophyl… Show more

“…However, many larvae can influence their horizontal distribution by controlling their vertical position (Nelson, 1912;Knights et al, 2006) and thus affect transport and spatial distributions on bottom habitats. Distributional patterns and behaviors are species-specific, but larvae are difficult to identify with traditional methods (Wong et al, 2014;Chen et al, 2013a; and knowledge on vertical distribution and behavior is lacking for most species.…”

“…Following collection, larvae are traditionally identified to gross taxonomic level. Invertebrate larvae are difficult or practically impossible to identify to species using morphometric methods (e.g., Wong et al, 2014;Chen et al, 2013a for barnacles), and processing time is often prohibitive with intensive sampling . Thus, larvae are often binned into super-specific groupings (e.g., 'bivalves' or 'nauplii') that confound interpretation of results.…”

“…Further experimental studies are needed to establish their efficiency in collecting other species or even other types of barnacle larvae. Chen et al (2013b) further developed an integrative trap that can collect zooplankton during both the submerged and swash periods. The integrative trap consists of two threaded sections of PVC piping (Fig.…”
