Sponges are among the most species-rich and ecologically important taxa on coral reefs, yet documenting their diversity is difficult due to the simplicity and plasticity of their morphological characters. Genetic attempts to identify species are hampered by the slow rate of mitochondrial sequence evolution characteristic of sponges and some other basal metazoans. Here we determine species boundaries of the Caribbean coral reef sponge genus Callyspongia using a multilocus, model-based approach. Based on sequence data from one mitochondrial (COI), one ribosomal (28S), and two single-copy nuclear protein-coding genes, we found evolutionarily distinct lineages were not concordant with current species designations in Callyspongia. While C. fallax,C. tenerrima, and C. plicifera were reciprocally monophyletic, four taxa with different morphologies (C. armigera,C. longissima,C. eschrichtii, and C. vaginalis) formed a monophyletic group and genetic distances among these taxa overlapped distances within them. A model-based method of species delimitation supported collapsing these four into a single evolutionary lineage. Variation in spicule size among these four taxa was partitioned geographically, not by current species designations, indicating that in Callyspongia, these key taxonomic characters are poor indicators of genetic differentiation. Taken together, our results suggest a complex relationship between morphology and species boundaries in sponges.

“…This is of great relevance given their sessile nature and the spatial patchiness of their habitat consisting mainly of coral calcareous structures. Available population genetics studies of Porifera refer mostly to non-excavating species (Duran et al 2004a, b, c;Bentlage and Wörheide 2007;Wörheide et al 2008;López-Legentil and Pawlik 2009;DeBiasse et al 2010), whereas those focused on coral-excavating sponges deal mostly with their molecular (Barucca et al 2007;Xavier et al 2010b;Escobar et al 2012; except for Chaves-Fonnegra et al 2015). The limited availability of polymorphic molecular markers has hindered the study of sponge molecular population genetics (reviewed by Uriz and Turon 2012).…”

“…Nevertheless, mitochondrial variation in the widely used and highly conserved COI gene has sometimes proven informative to address sponge evolutionary relationships (e.g., DeBiasse et al 2010;CruzBarraza et al 2012) and efforts have been made to develop new markers (Rua et al 2011). Internal transcribed spacers (ITS) of the nuclear ribosomal genes (rDNA) have also been successfully used in sponge phylogeography (Bentlage and Wörheide 2007;Wörheide et al 2008); however, intragenomic variation and low levels of polymorphism may limit their utility in some species (Lôbo-Hajdu and Guimarães 2004;Wörheide et al 2004;Escobar et al 2012). Intraspecific genetic surveys of sponges concur in finding significant levels of genetic structure at scales ranging from a few (Whalan et al 2005;Duran and Rutzler 2006) to more than 100 km (Benzie et al 1994;Solé-Cava and Boury-Esnault 1999;Duran et al 2004a, b, c;Duran and Rutzler 2006;Wörheide et al 2008;López-Legentil and Pawlik 2009;Blanquer and Uriz 2010;DeBiasse et al 2010;Xavier et al 2010a;Noyer and Becerro 2012).…”

Pervasive genetic structure at different geographic scales in the coral-excavating sponge Cliona vermifera (Hancock, 1867) in the Mexican Pacific

et al. 2015

Cliona vermifera is one of the most abundant excavating sponges in Mexican coral reefs, and represents a potential threat to their health. It appears to have limited dispersal potential, but, paradoxically, it is widespread over much of the 2000 km of Mexican Pacific waters, suggesting mechanisms of long-distance dissemination. Despite its ecological importance, nothing is known about its patterns of genetic structure and connectivity in space and time. In this study, we assess levels of genetic structure and test the hypothesis of limited dispersal and isolation by distance among coral reef systems in the Mexican Pacific. Genetic diversity levels were consistently low in DNA sequences from two mitochondrial genes and one nuclear gene; however, they revealed strong and significant genetic differentiation throughout the study region. Patterns of genetic differentiation from the slow-evolving mitochondrial, but not the nuclear, genes were geographic scale dependent. We found higher mitochondrial genetic similarity among localities at 10-100s km than at larger scales (100-1000s km). However, all samples were genetically differentiated at the nuclear locus, which is inconsistent with frequent longdistance dispersal. Significant isolation by distance is consistent with life history traits shared by boring sponges: a short larval period and larval philopatric behavior. The patterns of genetic differentiation in C. vermifera concur with those found in other sympatric coral species, and suggest the influence of community-wide ecological and genetic mechanisms on the genetic makeup of coral reef species in the Mexican Pacific. Fixed genetic differences suggest that the southern population of Oaxaca may be experiencing incipient speciation.

“…The taxonomic assignment of species in either the Spirastrellidae or Clionaidae has been debated (e.g., Anthosigmella varians (Rützler 2002, Hajdu et al 2011 and Cervicornia cuspidifera (Rützler & Hooper 2000)). Several examples of taxonomic challenges at the species level include the C. caribbaea (Carter, 1882), C. aprica Pang, 1973, and C. tenuis Zea & Weil, 2003 complex in the Caribbean (Zea and Weil 2003); C. parenzani Corriero & Scalera-Liaci, 1997 in the Mediterranean (Vacelet et al 2008); as well as the 'Cliona viridis (Schmidt 1862) complex' on the Great Barrier Reef (Schönberg 2000a,b;Escobar et al 2012).…”

Cliona tumula sp. nov. is described from the Florida Keys, Florida, USA. The new species is compared to representative Cliona spp. from the Caribbean and Indo-Pacific. Cliona tumula sp. nov. is a massive, mound-shaped zooxanthellate clionaid with a central, apical cluster of numerous oscula, slender tylostyles with variable heads and abundant, delicate spirasters with compound spines that can be concentrated at the ends, which in this species can appear as mushroom-like caps, with a skeleton in typical clionaid arrangement. It is distinguished from congeners by its epibenthic growth form that extends for 20-40 cm above the substratum, centrally located concentration of oscula, and calcareous fragments obtained from surrounding sediment that C. tumula sp. nov. incorporates in tracts that run through the choanosome perpendicular to the ectosome. This species can be locally abundant in the Florida Keys in patch reefs near sand flats, but may be restricted to the lower keys as it has not been observed on reefs to the east.
