“…Unlike terrestrial plant studies, marine studies rarely find that epifaunal abundance or diversity increases with the number of plant or algal species. Some confirm strong identity effects, finding that plant species vary in the animal communities they support (e.g., Parker et al 2001, Bates and DeWreede 2007, Gustafsson and Bostrom 2009. One study found that a diverse macroalgal community offered a superior predation refuge relative to the average monoculture but was no better at reducing predation than a community comprised of a single, highly folded macroalga (Moran et al 2010).…”

“…In marine systems, several studies have found strong effects of plant identity on the diversity and abundance of invertebrates when macrophytes vary in their morphology (Parker et al 2001, Bates and DeWreede 2007, Gustafsson and Bostrom 2009, while other studies have found redundancy among different macroalgae in the animal communities they support (Gibbons 1991, Kelaher et al 2007.…”

“…Despite an abundance of literature detailing variation among marine algae in the composition of their associated fauna (e.g., Holmlund et al 1990, Taylor and Cole 1994, Bates 2009) and evidence for distinct microhabitat preferences among co-occurring species (e.g., Hicks 1986, Hacker and Steneck 1990, Wieters et al 2009, Aguilera and Navarrete 2012, there have been relatively few explicit tests of the effects of marine producer diversity on animal diversity or abundance (Parker et al 2001, Bates and DeWreede 2007, Gustafsson and Bostrom 2009, 2011, Moran et al 2010.

Abstract. Considerable research has examined the influence of herbivores on the maintenance of plant diversity, but fewer studies have examined the reciprocal effect of plant diversity on the animals that use the plant community for food and shelter, particularly in marine systems. Several mechanisms could underlie such effects. Animal diversity and abundance could be increased by complementary use of different plants by different animals, or by an indirect effect of plant diversity on plant production that results in more total plant biomass in high plant-diversity communities. Alternatively, plant species identity could play a dominant role leading to sampling effects or no effect of diversity at all. We conducted a sixyear field manipulation of the richness of rocky shore seaweeds in northern California and measured the effects of algal richness and identity on the invertebrate community, from meiofauna to macrofauna. We found that diverse algal communities hosted more species of both large and small invertebrates than the average algal monoculture but that the mechanisms underlying this pattern differed substantially for organisms of different size. More species of macrofauna occurred in the polycultures than in any of the monocultures, likely due to the greater total cover of algae produced in polycultures. Rare and common macrofaunal taxa responded to host plant species richness in opposite ways, with more occurrences of rare taxa and lower abundance of very common taxa in the polycultures. In contrast, meiofaunal richness in polycultures was no different than that of monocultures of finely branched species, leading to strong effects of algal identity. Our findings are similar to those from terrestrial systems in that the effects of plant diversity we observed were most related to the greater amount of habitat in polycultures as a result of overyielding in algal biomass. However, our findings differ from those in terrestrial systems in that the primary mechanisms for both richness and identity effects appear related to the value of plants as shelter from harsh abiotic conditions or predation rather than food, and in that animal body size altered the mechanisms underlying diversity effects.

“…They also support the diverse assemblages of associated species by providing them a physical structure (Koch et al 2013;Leopardas et al 2014). Therefore, any changes in patterns of such habitat-forming species may create bottom-up changes in the food web and influence the associated fauna and flora (Bates and DeWreede 2007).…”

This study investigates the spatial and temporal variation of intertidal macroalgae along the eastern coasts of Qeshm Island, Persian Gulf, Iran. Monthly sampling of abundance, biomass, richness and diversity of macroalgae at three intertidal levels was carried out at two different sites during 1 year. The samples were collected every month using quadrats (0.5 × 0.5 m) from October 2012 to September 2013. The species dry weight was applied to examine changes in biomass and assemblage composition of intertidal macroalgae using univariate and multivariate analyses. A total of 42 seaweed species (10 Chlorophyta, 9 Phaeophyceae, and 23 Rhodophyta) were identified. The results confirmed a temporal pattern in the growth of the algal species which also showed a biomass zonation pattern from upper to lower intertidal. The annual mean biomass of macroalgae was highest in winter (29.3 ± 9.8 g dry wt m−2 ) and the lowest in autumn (17.3 ± 13.5 g dry wt m−2 ). The annual dominant species by biomass was Padina sp. followed by Padina australis. The most common species in the area, during the sampling period include Ulva intestinalis, Ulva lactuca, Palisada perforata and Padina sp. According to the similarity percentages analysis (SIMPER), the species Ulva intestinalis, Dictyosphaeria cavernosa (Chlorophyta), Padina australis (Phaeophyceae), Champia spp., Centroceras clavulatum and Palisada perforata (Rhodophyta) were responsible for the most dissimilarity of species composition between four seasons during the sampling period. BIOENV analysis indicated that the main environmental factors structuring macroalgal community at the study area were TDS and pH. The simple macroalgae community on the eastern coast of Qeshm Island and absence of slow-growing perennial macroalgae, such as members of the Sargassaceae, known from the lower shore at other intertidal localities along the island's coast might relate to the predominantly unsuitable sandy-stony substrates unsuitable for their colonization and the unfavourable impact upon them of urbanization.

“…Effects of invasion may be particularly serious when habitat-forming species are involved, as each change in population of these organisms may have severe effects on associated assemblages ). Macroalgae are important habitat-forming organisms in temperate coastal systems, providing a suitable habitat for many epiphytes and mobile invertebrates (Edgar and Moore 1986, Taylor and Cole 1994, Cacabelos et al 2010) and influencing the structure and the biodiversity of coastal systems (Tanaka and Leite 2003, Bates and Dewreede 2007, Wikström and Kautsky 2007.…”

Summary:The study compared the structure of mobile epifaunal assemblages associated with Mediterranean Cystoseira beds between areas invaded and not invaded by Lophocladia lallemandii. A total of 150 taxa were identified: 42 Polychaeta, 78 Arthropoda, 26 Mollusca and 4 Echinodermata. Epifaunal assemblages differed between areas invaded and not invaded by Lophocladia lallemandii when the invasive species reached maximum values of cover and biomass, while differences between conditions were not significant in other periods of the year. The main differences were the greater abundance of amphipods, isopods and polychaetes in invaded areas and the greater abundance of molluscs and decapods in non-invaded areas, while richness and total abundance of organisms were not significantly different between conditions. The effects of Lophocladia lallemandii invasion on Cystoseira-associated assemblages seem to be limited to the period of vegetative growth of the alga and reversible during the period of its vegetative rest.Keywords: biological invasions; Cystoseira crinita; Lophocladia lallemandii; Mediterranean Sea; mobile epifauna. Comunidad de epifauna móvil asociada a las bosques de Cystoseira: comparación entre áreas invadidas y no invadidas por Lophocladia lallemandiiResumen: Este estudio compara la estructura de la comunidad de macroinvertebrados móviles asociada a bosques mediterráneos de Cystoseira entre áreas invadidas por Lophocladia lallemandii y áreas no invadidas. Se identificaron un total de 150 táxones: 42 Polychaeta, 78 Arthropoda, 26 Mollusca, 4 Echinodermata. La comunidad epifaunal difirió entre áreas invadidas por Lophocladia lallemandii y áreas no invadidas cuando la Rhodophyta introducida alcanzó valores máximos de cobertura y biomasa, mientras que no presentó diferencias entre condiciones en otros períodos del año. Estas diferencias fueron principalmente debidas a una mayor abundancia de anfípodos, isópodos y poliquetos en áreas invadidas, y de moluscos y decápodos en áreas no invadidas, mientras que la riqueza y abundancia total de organismos no presentaron diferencias significativas entre condiciones. Los efectos de la invasión de Lophocladia lallemandii sobre las comunidades asociadas a Cystoseira parecen estar restringidos al período de crecimiento vegetativo del alga, siendo reversibles durante el período de pausa de crecimiento.
