“…To express the community functional structure in the analyzed cores, we used the biological traits approach (BTA) with a selected set of traits relevant for actuating flows of chemical substances, particularly fluxes of solutes, across the SWI and generally important for species-environmental relationships (Bremner et al, 2006;van der Linden et al, 2017). Table 2 provides the full list of 8 traits and 32 modalities considered.…”

“…Based on the affinity of species to a particular modality of each trait, partial BTA scores, ranging from 0 (no affinity) to 1 (exclusive affinity), are assigned for each species so that the sum of scores of all modalities of each trait would sum to one. This "fuzzy coding" approach allows each taxon and each biological trait to have the same weight in further analysis (Chevenet et al, 1994;Bremner et al, 2006;van der Linden et al, 2017). To code the taxa by their functional traits we have used scores published in Gogina et al (2014).…”

“…Many polychaetes species of family nereidid inhabit estuary ecosystems (Pederson et al 2010;Saito et al 2014;Linden et al 2017) subjected to a high degree of variability in their environmental conditions, especially salinity variation due to freshwater and seawater inputs (Hernández-Alcántara et al 2014). Such dynamic environmental conditions were presenting a number of problems for externally fertilizing species, and consequently, their fertilization success might occur in an optimum range of medium salinity.…”

Abstract. Junardi, Anggraeni T, Ridwan A, Yowono E. 2020. Larval development of nypa palm worm Namalycastis rhodochorde (Polychaeta: Nereididae). Nusantara Bioscience 12: 148-153. Namalycastis intensive culture is still facing problems in mass production due to limited information on reproduction, especially in fertilization and production of larvae. The present research was designated to find out optimum salinity for fertilization and the production of nypa palm worm larvae (Namalycastis rhodochorde). Gamete samples were collected using a capillary glass tube inserted into ventro-lateral part of a body segment of a mature worm. Artificial fertilization was done by mixing the sperms and oocytes in a fertilization dish containing sterilized seawater as the medium. The larval development was observed until the benthic phase larvae (3-setigers). Fertilization was performed in medium salinity of 7-21‰ and water temperature of 25-29°C. The cleavage and larva stage occurred respectively within 28.20 to 58.67 minutes and within 72 to 80 hours after fertilization. The fertilization and larval development of N. rhodochorde were highly influenced by the medium salinity and temperature.

“…Polychaetes, a diverse group of marine worms, usually dominate the macrobenthic communities of coastal areas (Rouse & Pleijel 2001;Musco 2012;Dorgham et al 2014). These annelids display a high functional trait plasticity, and putatively a high functional diversity (Martin & Bastida 2006;Otegui et al 2016;van der Linden et al 2017) with many supported functions or roles in benthic ecosystems. Polychaetes actively participate in relevant marine ecological processes, such as bioturbation, which contributes to aerating and remobilizig the sediment, nutrient cycling, secondary production, and energy flow (Faulwetter et al 2014;Dolbeth et al 2015;van der Linden et al 2017;Wouters et al 2018).…”

Functional redundancy assumes a critical relevance nowadays due to the serious threats that affect marine life worldwide. We assessed and compared levels of functional redundancy in polychaete assemblages from the continental shelf and from estuarine environments along the South Brazil Shelf Large Marine Ecosystem (SBSLME). To quantify functional redundancy, we used functional originality (FOri) and functional uniqueness (FUni). We found 57 and 47 polychaete taxa distributed in 48 and 41 functional entities (i.e., a unique combination of trait values) in continental shelf and estuarine environments, respectively. Results suggest a low level of functional redundancy in both environments. However, FOri was higher in the estuarine environment, whereas FUni was higher in the continental shelf. As expected, estuarine polychaetes have fewer unique combinations of trait values, but these combinations are more original and adequate to the varying conditions imposed by estuarine environmental drivers.
