Mediterranean Red Macro Algae Mats as Habitat for High Abundances of Serpulid Polychaetes

چکیده
The Mediterranean Sea harbors more than 17,000 eukaryotic marine species, with several ecosystems recognized as biodiversity hotspots, such Posidonia oceanica meadows. Recent research indicates that benthic mats formed by the fleshy red alga Phyllophora crispa are also associated high species richness. Among key groups found in these sessile polychaetes, which live epiphytes on algae thalli. Knowledge of abundance, richness, and spatial variation polychaetes habitats is still scarce. We carried out a comparative assessment focusing serpulid within samples from P. neighboring meadows at six different sampling sites around Giglio Island (Tyrrhenian Sea, Italy). A total 17 taxa were identified. abundance serpulids (5665 individuals m−2 mat) similar to (2304 leaves 5890 shoots). number was significantly higher (average 6.63 ± 1.32 taxa) compared beds 1.56 0.63 1.84 1.04 shoots, respectively). Within habitat type, there no significant differences richness between sites. most abundant Josephella marenzelleri (61% individuals), while Vermiliopsis spp. Bathyvermilia sp. exclusively samples. Our results highlight host an exceptional diversity should be included conservation strategies. Further focus significance other important taxonomic evaluate distribution regions Sea.

متن کاملVariable discharge alters habitat suitability for benthic algae and cyanobacteria in a forested Mediterranean stream
Large-scale algal community patterns can be understood by studying organisation within patches. Spatial heterogeneity in light and substratum type may affect the biomass and community composition of benthic algae and cyanobacteria. We compared the effects of these factors at the species level in two reaches differing in canopy cover in a forested Mediterranean stream in winter (high water flow)...

Aqueous and ethanolic extracts obtained from nine Chilean marine macro-algae collected at different seasons were examined in vitro and in vivo for properties that reduce the growth of plant pathogens or decrease the injury severity of plant foliar tissues following pathogen infection. Particular crude aqueous or organic extracts showed effects on the growth of pathogenic bacteria whereas others...
