“…A significant increase in rhizome growth rate and a decrease in rhizome production and weight/length ratio have been observed in rhizomes colonized by the bryozoan Calpensia nobilis (Romero‐Colmenero & Sanchez‐Lizaso ; Cigliano et al . ). This organism is able to form thick calcareous muff‐like structures that circum‐encrust rhizomes, affecting the plant in a similar fashion to high sedimentation rates (Romero‐Colmenero & Sanchez‐Lizaso ).…”

This paper reviews the main studies dealing with epiphytes of both leaves and rhizomes of Posidonia oceanica, the main seagrass found in the Mediterranean Sea. A total of 660 epiphyte species has been recorded, including 430 on leaves and 437 on rhizomes. Of these, 205 are Rhodophyta, and 19 Tunicata. The epiphyte assemblages demonstrate a gradient of dissimilarity from west to east, with the eastern area being the most unlike the others. The differences can be attributed mostly to rare species that differ amongst the Mediterranean regions. Many of the dominant taxa have been found in all meadows studied. Data concerning species composition, abundance, and patterns of spatial and temporal variability are summarized, and biotic and abiotic factors controlling the structure of assemblages are discussed. Responses of epiphyte assemblages to anthropogenic stressors, such as nutrient enrichment and biological invasions, are discussed in relation to the use of epiphytes as ecological indicators.Marine Ecology.

“…The articulated erect species Cellaria salicornioides (Lamouroux) forms 'meadows' off Croatia (McKinney and Jaklin 2000 ; Novosel 2005 ), described as one of the largest unbroken areas of bryozoans known, more than 100 × 100 m in extent and attaining 80-90 % bryozoan cover. Through successive phases of regeneration and overgrowth, multilayered encrusting colonies of Calpensia nobilis form thick cylinders on every kind of hard substrate, particularly on rhizomes of the seagrass Posidonia oceanica in southern Spain and in Ischia Strait, Naples (Romero Colmenero and Sanchez Lizaso 1999 ; Cigliano et al 2007 ).…”

“…Cryptic microhabitats often shelter bryozoan-dominated assemblages containing numerous species (Harmelin 1985 ). Mediterranean bryozoan bioconstructions are usually characterized by encrusting multilaminar sheets which are able to form dome-like colonies, wrapping other organisms or inert substrates (Cigliano et al 2007 ;Cocito et al 2012 ;Kocak et al 2002 ;Poluzzi and Coppa 1991 ), and also by large erect arborescent colonies with multilaminar and/or robust branches (Cocito 2004 ;Cocito et al 2004 ;Lombardi et al 2008a ;McKinney and Jackson 1989 ;Novosel 2005 ) Strongly calcifi ed marine bryozoans are important producers of modern temperate carbonate sediment, both in the Mediterranean (Fornos and Ahr 2006 ;Bayhan et al 2001 ) and elsewhere (e.g. James and Bone 2010 ).…”

Bryozoans in the Mediterranean Sea are recognized as bioconstructional framework builders, both primary builders that construct frameworks alone or in combination with other organisms, or secondary builders that play various functional roles. Ten bryozoan species or complexes of species in the Mediterranean are responsible for providing habitats for diverse species and assemblages, thus playing important roles in promoting biodiversity and habitat heterogeneity. Four habitat-forming bryozoans respond to climatic changes (global warming and ocean acidifi cation) by altering their colony growth, zooidal morphology and development, skeletal mineralogy and geochemistry. Under conditions of reduced pH, these species reallocate energy resources within the colony by regulating zooid size, proportion of polymorphs, number of zooidal generations, colony growth rate, and investment in the organic components involved in biomineralizational processes. Mediterranean 'bryoconstructions' are suitable 'ecosystem models' to be monitored in the context of climate change, especially ocean acidifi cation and warming.

“…It is also recorded in the eastern Atlantic southwards along the northwest African coast and northwards to the Gulf of Saint-Malo and the Channel Isles [ 34 , 35 ]. Occurring from 10 to 30 m in depth, single-layered or multilayered encrusting colonies grow on several types of hard substrates, including rocks, shells, man-made objects, such as glass and ceramics, as well as other marine animals and plants [ 27 , 34 , 35 ].…”

Morphological plasticity in a calcifying modular organism: evidence from an in situ transplant experiment in a natural CO ₂ vent system

Understanding is currently limited of the biological processes underlying the responses of modular organisms to climate change and the potential to adapt through morphological plasticity related to their modularity. Here, we investigate the effects of ocean acidification and seawater warming on the growth, life history and morphological plasticity in the modular bryozoan Calpensia nobilis using transplantation experiments in a shallow Mediterranean volcanic CO2 vents system that simulates pH values expected for the year 2100. Colonies exposed at vent sites grew at approximately half the rate of those from the control site. Between days 34 and 48 of the experiment, they reached a possible ‘threshold’, due to the combined effects of exposure time and pH. Temperature did not affect zooid length, but longer zooids with wider primary orifices occurred in low pH conditions close to the vents. Growth models describing colony development under different environmental scenarios suggest that stressed colonies of C. nobilis reallocate metabolic energy to the consolidation and strengthening of existing zooids. This is interpreted as a change in life-history strategy to support persistence under unfavourable environmental conditions. Changes in the skeletal morphology of zooids evident in C. nobilis during short-time (87 days) exposure experiments reveal morphological plasticity that may indicate a potential to adapt to the more acidic Mediterranean predicted for the future.
