“…Therefore, epibionts and seagrasses have coevolved since the end of the Mesozoic, which has conduced to highly adapted biocenosis with complex interactions with the substrate and among the different organisms forming such communities. Nowadays, the appearance of erect bryozoans such as R. grimaldii on rocky bottom meadows (Reverter-Gil and Fernández-Pulpeiro 1999) and in association with the seagrass rhizomes (Ben Mustapha et al 2002, Heß 2004) has been documented.…”

Interaction between the invasive macroalga Lophocladia lallemandii and the bryozoan Reteporella grimaldii at seagrass meadows: density and physiological responses

et al. 2009

Invasive epiphyte Lophocladia lallemandii macroalga induces changes in the erect bryozoan Reteporella grimaldii at shallow Posidonia oceanica meadows at a Mediterranean pristine location. Bryozoan densities at noninvaded seagrass plots (88.32 ± 3.11 colonies m -2 ) are higher than those at invaded plots (13.39 ± 1.09 colonies m -2 ) with a fourfold decrease in number of colonies. Activation of enzymatic pathways (catalase, superoxide dismutase, glutathione peroxidase) and increase in lipid peroxidation malondialdehyde (MDA) [0.80 ± 0.06 nmol/mg prot at Posidonia oceanica plots to 1.08 ± 0.04 nmol/ mg prot at L. lallemandii (P \ 0.05)] is observed on sessile bryozoans as response to anoxia caused by L. lallemandii. d 13 C of bryozoan isotopic composition differed among treatments, covering a broad range (-19.30% invaded to -2.84% at noninvaded plots), suggesting modification of food sources. Induced shifts of a filter-feeding erect bryozoan by dense algal turfs at invaded seagrasses are demonstrated, highlighting the need to further address interaction across natural communities and alien species invaded systems before further cascade effects are driven.

“…On the other hand, some extensive, deep water oceanographic surveys in the 19th and 20th Centuries were carried out close to the Portuguese coasts, and the results reported by Wyville Thomson (1877) (possibly the oldest reference), Jullien (1882), Busk (1884), Calvet (1906, 1931), Harmer (1915), d'Hondt (1974), Hayward (1979) and d'Hondt & Hayward (1981). Other authors who have also contributed to knowledge of the Portuguese Bryozoa include Pérès (1959), Gautier (1961), Prenant & Bobin (1966), Marques et al (1982), Reverter-Gil & Fernández-Pulpeiro (1999a, 2005, 2007), Boury-Esnault et al (2001), Harmelin (2001) and Marchini et al (2007). As far as we know, no other studies have included reports of bryozoan fauna from Portuguese waters; therefore we believe that to state that the literature is rather scarce is an understatement, especially as some of these studies only concern a single species, or a few nominal citations.…”

Gymnolaemate bryozoans from the Algarve (southern Portugal): new species and biogeographical considerations

2010

Three sampling surveys were carried out, by SCUBA diving, in the Algarve (southern Portugal) in December 2007. A total of 57 species of gymnolaemate Bryozoa were identified. Of these, eight species were new to science (Mollia cristinae sp. nov., Hippoporina teresae sp. nov., Schizoporella spinosa sp. nov., Fenestrulina inesae sp. nov., Celleporina derungsi sp. nov., Dentiporella saldanhai sp. nov., Rhynchozoon celestinoi sp. nov. and Rhynchozoon rosae sp. nov.). Another 16 species are cited for the first time in Portuguese waters; of these, Stephanollona contracta is cited for the first time in European continental waters. Reference material deposited in several collections was also revised, and lectotypes and paralectotypes were selected for Mollia multijuncta and Dentiporella sardonica, species subjected to diverse interpretations. In addition Rhynchozoon revelatus was found to be a junior synonym of D. sardonica. The species collected in the study area reflect the existence of Lusitanian, Mauretanian and Mediterranean influences; the latter influence is of interest as the Mediterranean species found were previously considered endemic to the Mediterranean Sea and are usually found in shallow waters. Finally, a large degree of intracolonial variability was observed in some of the species studied, especially in Stephanollona armata, which may be taken into account in studies of the geographical variability and differentiation of cryptic species.

“…It was covered by many bryozoan colonies. The species have already been reported in several taxonomic papers (Reverter-Gil and Fernández-Pulpeiro 1999a, 1999b, 2001Reverter-Gil et al 2019a, 2019b (Table 1). The bryozoan fauna of the Iberian Peninsula as a whole is well known, although the studies are irregularly distributed, both geographically and bathymetrically.…”

Bryozoan diversity on a whale bone: an uncommon substrate from the continental shelf off NW Spain

Carcasses and bones of whales are interesting yet poorly understood habitats for invertebrates and microbial communities. Nevertheless, bryozoans have never before been reported in this particular habitat at the present day. Here, we present the first study on a bryozoan community colonizing a whale bone from the continental shelf off NW Spain at 128 m depth. Thirty-three species of bryozoans were identified, representing 50% of the known bryozoan diversity from this area and depth range. Despite this high biodiversity, no potential whale-fall specialists were detected: all the species are already known in the area, with several being more frequent in shallower or deeper waters. Our results support the hypothesis that the number of specialist taxa on whale-fall habitats decreases drastically on whale remains at depths of less than 260 m. These results also support the theory that whale-falls can serve as intermediate habitats where no other suitable substrate is present, facilitating habitat colonization.
