“…In order to define the functional role of bioconstructors, definitions of growth form and growth habit by Fagerstrom (1988Fagerstrom ( , 1991, Insalaco (1998) and Wood (1999) have been compared with references to skeletal properties (size and strength), growth direction and functional morphology.…”

“…According to Fagerstrom (1991), assignment of an organism to a particular building group is based on its growth form and growth habit. Erect and large, well-skeletonized mound or branched organisms, belonging to the functional unit of 'constructors', provide most of the volume and rigidity to the framework if compared to encrusters, which expand and unite the components of the framework and the settling sediment, these last belonging to the functional unit of 'binders'.…”

SUMMARY: This paper describes the functional role of main benthic constructor organisms and reviews processes by which bioconstructions increase diversity and abundance of associated biota, and the reverse. Based on the literature, patterns of diversity of carbonate bryozoan bioconstructions, one of the most important groups performing important constructional roles, have been analysed. Diversity of bryozoan bioconstructors seems not to follow the latitudinal gradient, from tropics to increasing distance from tropics, recognised for coral bioconstructors. The only case of a "high diversity bryozoan reef" (Joulters Cays, Bahamas) represents a situation virtually unique in carbonate environments. Dimension and extension of bryozoan bioconstructions show their maximum in temperate environments, where seasonality or variability of environmental parameters could afford advantages for success to bryozoans. With only one exception (the bryozoan-serpulid build-ups from South Australia), diversity of biota associated with bryozoan bioconstructions is high, but comparison is not possible due to the fact that exhaustive faunal studies are rare, sometimes referring only to one taxon, and environments differing in depth range, salinity, hydrodynamics, trophic diversity, etc. are involved.Key words: biodiversity, biological habitat provision, bioconstructor, physical habitat structure, associated fauna, Bryozoa. RESUMEN: BIOCONSTRUCCIÓN Y BIODIVERSIDAD: SU INFLUENCIA MUTUA. -Se describe el papel funcional de los principales organismos bentónicos constructores y se revisan los procesos por los que las bioconstrucciones aumentan la diversidad y la abundancia de la biota asociada, y al revés. Sobre la base de la bibliografía, se han analizado los patrones de diversidad de las bioconstrucciones carbonatadas de los briozoos, uno de los grupos más importantes por su papel constructor. La diversidad de los briozoos en tanto que bioconstructores no parece seguir el gradiente latitudinal, desde los trópicos hasta distancias crecientes de éstos, que se ha reconocido para los bioconstructores que son los corales. El único caso de "arrecife de briozoos de gran diversidad" (los cayos Joulters, Bahamas), representan una situación prácticamente única en ambientes carbonatados. La dimensión y la extensión de las bioconstrucciones de briozoos presentan su máximo en ambientes templados, en los que la estacionalidad o la variabilidad de los parámetros ambientales pueden proporcionar ventajas para el éxito de los briozoos. Con una sola excepción (los edificios de briozoos y serpúlidos de Australia del Sur), la diversidad de la biota asociada con las bioconstrucciones de briozoos es elevada, pero no es posible la comparación debido al hecho de que los estudios faunísticos exhaustivos son raros, a veces se refieren únicamente a un táxon, y a que se trata de ambientes que difieren en rango batimétrico, salinidad, hidrodinamismo, diversidad trófica, etc.Palabras clave: biodiversidad, provisión de hábitat biológico, bioconstructores, estructura físic...

“…Large mounds of the Phanerozoic apparently built upon a higher complexity, a higher level of diversity, a "social" organization ruled by consortia of microbes and metazoans, functionally organized in "guilds" (Fagerstrom, 1991) as constructors, bafflers and binders. To these builders, one should add the destroyers and dwellers.…”

“…Several stromatoporoids (Actinostroma) only appear to locally bound other bioclasts. According to Fagerstrom's (1991) theory of reef guilds, the Aferdou el Mrakib fauna is compatible with a constructor guild and a baffler guild. The predominance of stromatoporoids and rugose corals as well as the absence of calcareous green algae suggests a moderately shallow environment below the euphotic zone (Kaufmann 1995(Kaufmann , 1996.…”

The collection and study of benthic fauna from Middle Devonian carbonate buildups of the Maïder Basin in the eastern Anti-Atlas of Morocco permitted the taxonomic revision of previously described brachiopods from this area. Rhynchonellids dominate the brachiopod fauna. In this work, however, the focus is put on the description of a new gypidulid species, Ivdelinia pulchra, which belongs to the family Gypidulidae (subfamily Ivdelininae), found among the brachiopods from the Aferdou el Mrakib reef mound. It represents the youngest Ivdelinia species so far described and is compared with other ivdelinids. Ivdelinia pulchra occurs as densely packed communities which lived in a carbonate predominant environment during the earlier stage of reef mound growth, suggesting a more or less allochthonous state of these communities. However, this taxon does not properly belong to the reef guild. In addition we discuss the palaeoecology of the new species
