“…D. cristatum is a dioic species that is sexually mature from November to June (D'Ancona Lunetta & Damiani 2002;Templado et al 2015). The spermatophores are pelagic, which is a peculiarity of the Vermetidae.…”

“…The only other marine invertebrates that have pelagic spermatophores are few sessile tubicolous organisms, but no other aquatic gastropods (Calvo & Templado 2005). Ovaries appear at the beginning of the summer, while embryos occur in capsules within the mantle cavity of the females from June to October (D'Ancona Lunetta & Damiani 2002). Along the Sicily coast, Templado et al (2015) found that females brood up to 14 egg capsules (with a maximum diameter between 1.6 and 2.2 mm), with each capsule containing up to 30 embryos (with diameters between 0.35 and 0.41 mm).…”

In the Mediterranean, the gastropod Dendropoma cristatum (sin. D. petraeum (Monterosato, 1884)) is the primary builder of the vermetid reef, an intertidal bioconstruction of exceptional ecological importance. Despite awareness of the need for conservation of this key species, the biology of D. cristatum remains poorly understood. The recruitment of D. cristatum deserves particular attention because the absence of a planktonic larval stage limits its dispersal ability. We examined the temporal pattern of recruitment during the breeding season of D. cristatum from June to September in 2013. Specifically, we compared the two portions of the vermetid reef (i.e. the inner edge and the outer edge) at localities with different exposures to wave motion. The number of recruits peaked in July, when it was significantly higher in the outer than in the inner edge. No differences emerged between localities with different wave exposures; however, the width of the reef was significantly related to the exposure index. Although there are still several gaps in our knowledge of the recruitment dynamics of D. cristatum, this study contributes to characterising recruitment rate variation at small spatial and temporal scales.

Reef building Mediterranean vermetid gastropods: disentangling the Dendropoma petraeum species complex

2015

A previous molecular study has revealed that the Mediterranean reef building vermetid gastropod Dendropoma petraeum conforms a complex of at least four cryptic species with non-overlapping distribution areas. Once detected specific genetic differences, ‘a posteriori’ searching for phenotypic characters has been undertaken to differentiate cryptic species and to formally describe and name them. The name D. petraeum (Monterosato, 1884) should be restricted to the species of this complex distributed around the Central Mediterranean (type locality in Sicily). In the present work we redescribe this taxon under the older valid name D. cristatum (Biondi, 1857), and we describe the new species of this complex distributed in the western Mediterranean. These descriptions are based on a comparative study focusing on the protoconch, teleoconch, external and internal anatomy. Both species can be only distinguished on the basis of non-easily visible anatomical features. Further, protoconchs differ in size and sculpture. On the other hand, some differences between both species are evidenced in features of the intracapsular larval development: the number and size of the egg capsules brooded per female at the same time, the number of egg/embryos per egg capsule, egg diameter and type of intracapsular nutrition.

“…Current research works are mainly focused on the reproductive biology of vermetid species from different areas along the Mediterranean coasts (e.g., Spain [14], Italy [15], Israel [16,17], western and central Mediterranean [18]). Conversely, there are few studies regarding fauna associated with the vermetid bioconstructions.…”

Assessment of Structural and Functional Diversity of Mollusc Assemblages within Vermetid Bioconstructions

et al. 2018

Dendropoma lebeche is a prosobranch gastropod belonging to the family Vermetidae, which calcifies its shell on hard substrates in dense aggregates, forming biogenic constructions along the western Mediterranean intertidal habitat. It is an important ecosystem engineer and, due to its ecological value, is protected by international convention. The aim of this study is to investigate the mollusc composition and diversity occurring within Spanish vermetid bioconstructions. During the late summer 2013, three distant sites along the Mediterranean coast of Spain were sampled by scraping off the vermetid shells to study their associated assemblages. A total of 600 molluscs were identified within the classes of Polyplacophora (four species), Gastropoda (35 spp.) and Bivalvia (18 spp.). Multivariate analyses revealed significant differences in composition and trophic diversity of mollusc assemblages among the three sites, highlighting a clear geographical gradient. Overall, both herbivores (grazers and deposit feeders) and omnivores were the quantitatively dominant trophic groups, while carnivores (predators and ectoparasites) were very scarce. Our results point out that mollusc assemblages associated with vermetid bioconstructions are rich and diversified, both in populations structure and trophic diversity, confirming the important role of vermetid gastropods as ecosystem engineers and biodiversity enhancers in shallow coastal waters.
