Specifically, it was aimed to assess the relationship between the presence of YBD and WPII on stony corals (Orbicella and Montastraea) with 1) water depth and 2) abundance of poriferan
sponges in 1-meter radius.
Adherens junctions are ubiquitous in epithelia of metazoans, except for some poriferans
(Dickinson et al., 2011; Leys and Riesgo, 2011; Miller et al., 2013).
crabs, shrimps, lobsters), poriferans
(sponges) and populations of larger sea animals such as hawksbill and green turtles, dugongs, and saltwater crocodiles, to name a few.
1), both Cambrian communities were rich in genera of arthropods and poriferans
. Chordates and molluscs also are more diverse today, while poriferans
, priapulids, cnidarians and hyolithids are absent from the modern community.
Abstract: A suite of fossils collected from the Warsaw Formation (Mississippian) of Missouri includes brachiopods, bryozoans, cnidarians, poriferans
, echinoderms, and chondrichthyan teeth.
showed similar concentrations of N, about 3.6% dw A significant difference was found in N content of the two species of cnidarians analyzed (P < 0.001), with the sea anemone B.
For example, the osmotic regulation was studied in poriferans
, mollusks, crustaceans and cnidarians.
In tropical waters, photosynthetic symbiosis is known to occur in various metazoans, such as poriferans
, cnidarians, flatworms, bivalves, nudibranchs, and ascidians.
The sponges, Poriferans
, were found to have some of the greatest diversity of both body size and species, ranging from microscopic to the size of an automobile.
Cambrian tropical mudflats were characterized by the adaptive radiation of two contrasting groups: the vagile arthropods and the sessile poriferans
. Arthropods were later replaced as the dominant benthic taxon by polychaetes.
This pattern of junction development parallels in some respects the evolutionary history of cell-cell junctions, with poriferans
exhibiting transient spot junctions, and belt-like junctions forming in cnidarian, ctenophore, and bilaterian taxa (Green and Bergquist, 1982; see Fig.
