Special Issue Information

Dear Colleagues,

Considering the dominant role of phytoplankton in primary production in the sea and oceans, it is understandable that filter-feeding is widespread and filter feeders (or suspension feeders) are found in almost all marine and aquatic animal classes. Filter-feeding animals are necessary links between suspended food particles (phytoplankton, free-living bacteria, and other members of the microbial loop) and higher trophic levels in marine food webs. In addition to many holo- and meroplanktonic organisms, such as copepods, pelagic tunicates, and invertebrate larvae that graze on phytoplankton and other food particles in the water column, many filter-feeding animals such as bivalves, polychaetes, ascidians, bryozoans, and sponges graze on phytoplankton in the near-bottom water. Particularly in shallow coastal waters and fjords, dense populations of filter-feeders may exert a pronounced grazing impact, which may keep the water clear (but not clean) in eutrophicated areas. On the contrary, dense populations of filter-feeding jellyfish and ctenophores in such areas may exert a pronounced predation impact on grazing zooplankton, resulting in phytoplankton blooms and making the water green. In addition, blooms of open-ocean filter-feeding pelagic tunicates such as pyrosomes and salps can control the populations of primary and secondary producers.

This Special Issue focuses on several related topics: bioenergetics and energy budgets, filter-pumps, particle capture mechanisms and retention efficiency, the grazing impact of filter feeders, the predation impact of jellyfish and ctenophores as well as the grazing impact of pelagic tunicates, and interactions between jellyfish and other zooplankton.

We invite researchers to submit articles that advance our understanding of filter-feeding in marine invertebrates.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Marine Science and Engineering is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Keywords

  • filter-feeding in marine invertebrates (planktonic and benthic species)
  • bioenergetics (food uptake, assimilation, respiration, energy budgets)

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Microplastics Uptake by Four Filter Feeders

Microplastics (MPs) are insidious plastic particles with sizes ranging from 1 to 5000 µm. Their presence has been reported all over the world. Recently, bioremediation to remove MPs from water columns using filter feeders as biofilters has been proposed. In a previous lab experiment, the MP bioremediation potential of four fouling organisms from a mariculture facility (Mytilus galloprovincialis, Sabella spallanzanii, Phallusia mammillata, Paraleucilla magna) was separately assessed in single-species experiment. Herein, a follow-up of the work is presented using a multi-species approach. The four organisms were placed together in the same 5 L beaker and fed with a concentration of 250 p/L 6 µm red polystyrene discernible particles. After digesting the organisms and counting the MPs in both the water and the organisms, the results of the two experiments were compared. In the previous experiment, S. spallanzanii had the highest particle retention (PR) value (PR = 88.01%), while in this experiment, P. mammillata has the lowest PR value (PR = 31%). The multi-species approach resulted in a higher number of plastics being removed from the water (88%) compared to the single-species experiments. These fouling organisms naturally exist as a community, acting as an efficient filter with complex morphologies and hydrodynamic features. Here, this simple marine animal forest is re-evaluated by exploiting the ecosystem services provided by these organisms as a solution to MP pollution problem in a mariculture environment.

Oxygen Extraction Efficiency and Tolerance to Hypoxia in Sponges

Sponges have always been filter feeders, in contrast to all the other filter-feeding invertebrate groups for which this feeding mode is a secondary adaptation. This study calls attention to this aspect, which explains why sponges are tolerant to hypoxia, but probably not more tolerant than the other filter-feeding invertebrates. The measurement of respiration rates at decreasing oxygen concentrations along with an estimation of the oxygen extraction efficiency in the marine demosponge Halichondria panicea have been used to understand why sponges are tolerant to low oxygen concentrations. It was found that the respiration rate was constant down to about 1.5 mL O2 L−1, which shows that the extraction efficiency increases with a decreasing oxygen concentration. It is argued that the relationship between the filtration rate and oxygen consumption in filter feeders is controlled by the resistance to the diffusion of oxygen across the boundary layer between the feeding current and the tissues of the body. A high tolerance to hypoxia is a consequence of the adaptation to filter feeding, and sponges do not have a special capacity to overcome hypoxic events. Full article
