Cryptic species and colonization processes in Ophryotrocha (Annelida, Dorvilleidae) inhabiting vertebrate remains in the shallow‐water Mediterranean

Over the past several years, there has been growing interest in how bones of decaying mammals are colonized in the marine seabed. One of the most common opportunistic taxa occurring worldwide on bones is dorvilleid polychaetes of the genus Ophryotrocha. In a recent study in the Mediterranean, Ophryotrocha puerilis and Ophryotrocha alborana were two of the most abundant species occurring in experimentally deployed bones. These species have direct development and this makes them a suitable model to study the mechanisms and processes allowing organisms lacking a dispersive larval phase to colonize new substrates. Here, we address the colonization processes at the molecular level for populations of O. puerilis and O. alborana on experimentally deployed mammal bones in the shallow‐water Mediterranean collected over a year at 3‐month intervals. High genetic distances between some of the O. puerilis organisms collected indicated the occurrence of at least two cryptic sibling species (O. puerilis ‘Shallow’ and O. puerilis ‘Deep’) apart from O. puerilis sensu stricto. This was corroborated with phylogenetic analyses using an alignment of three concatenated genes (COI, 16S, H3) and with species delimitation analyses using COI. The haplotype network inferred from COI sequences for O. puerilis ‘Shallow’ showed a few common haplotypes shared between the two trimesters analysed and several other less represented haplotypes only present in one trimester. Thus, colonization of these experimental bones may have been achieved by a few organisms that arrived to the bones and were able to reseed, and by several individuals arriving to the experimental bones and not persisting across time. In contrast, the haplotype network for O. alborana revealed that none of the haplotypes present in three different trimesters were shared, suggesting that the populations arriving at the bones during each trimester were totally replaced by new individuals during the subsequent trimesters. Our study suggests that different species of shallow‐water Ophryotrocha occurring in the Mediterranean may have different patterns of substrate colonization despite sharing similar life histories.

“…The present study is the third in a series in which we analyse putative cryptic polychaete species complexes in Scandinavian waters. In the second of these papers (Nygren et al 2009) we analysed a species group with a wide geographical distribution and differences in maximal size; in the first (Nygren et al 2005) and the present paper we analyse species groups with variation in colour and habitat preferences. The results from our phylogenetic analyses confirm that the deep and the shallow form of N. foliosum represent two genetically distinct species.…”

Cryptic species of Notophyllum (Polychaeta: Phyllodocidae) in Scandinavian waters

2010

The phyllodocid polychaete Notophyllum foliosum occurs in two colour morphs in Swedish and Norwegian waters, one palish yellow to grey form with black patches that is restricted to deeper waters and often associated with reefs of the deep-water coral Lophelia pertusa, and one usually yellow-orange form with black patches and white spots that is usually encountered on more shallow bottoms. We have sampled the two forms from sympatric occurrences in Norway, and the shallow form from the Swedish west coast. Phylogenetic and haplotype analyses based on the mitochondrial cytochrome c oxidase subunit I (COI) gene and the nuclear internal transcribed spacer region (ITS1-5.8SrDNA-ITS2) unequivocally indicate that the two forms represent different species. We apply the name N. foliosum (Sars, 1835) to the 'shallow form', and propose N. crypticum n. sp. for the 'deep form'. A lectotype is fixed for N. foliosum.

“…At the time of this study it was not possible to identify Nereimyra with certainty to species. However, according to a detailed study by Nygren et al (2005), the species in this area is most likely Nereimyra punctata. The bivalves Mya truncata and Spisula subtruncata have larvae that settle in the winter months (Rasmussen 1973), and are thus not disturbed by the extensive filtration of Upogebia during the warmer months.…”

The macrofauna from a shallow (12 m), sandy bottom at Bredholmen in the outer Lysekil archipelago, western Sweden, was collected quantitatively with a suction sampler at regular intervals between June 1980 and August 1981. This area was inhabited by a dense population of the burrowing crustacean Upogebia deltaura, with a rich infaunal community, high in abundance and diversity throughout the study period. A total of 7297 individuals comprising 126 taxa were obtained from the 52 samples (four replicates on each occasion). A total of 64 polychaete taxa were found, followed by 22 molluscs, 21 crustaceans, 7 echinoderms, and 12 species not belonging to any of these taxonomical groups (varia). Molluscs dominated in abundance throughout the study period except , when polychaetes dominated. Species abundance varied seasonally. The multivariate analyses of abundance data also demonstrated a limited temporal change, less pronounced during winter months. Bottom water salinity was negatively correlated to the number of taxa. Bottom water temperature was negatively correlated to polychaete abundance, and positively correlated to mollusc abundance. Upogebia deltaura correlated positively with four taxa: Nereimyra sp., Spisula subtruncata, one species within the family Talitridae, and Mya truncata, and negatively to Scoloplos armiger.
