Conservation and management of coral reef ecosystems will depend on accurate assessments reef-building species diversity. However, the true diversity corals may be obfuscated by presence cryptic species, which are likely much more pervasive than is currently recognised. Additionally, sometimes hybridize, resulting in gene introgression between species. Here, we investigate prevalence via a structured literature review find that over 50% population genomic studies show evidence for divisions within taxonomically recognised such closely-related taxa often linked flow. We frequently segregate environment, especially depth, differ phenotypic characteristics including resilience to heat stress. This hidden biodiversity creates challenges conservation restoration planning not well appreciated, hiding declines, biasing estimates species’ breadth, overestimating stressors, yielding uncertainty evolutionary dynamics inferred from past studies, creating reproductive barriers limit mating local translocated corals. Increasing awareness with incomplete boundaries common building this expectation into plans an important pathway forward. Rich opportunities interdisciplinary collaboration among speciation biologists could fill key knowledge gaps relevant conservation. detail recommendations best practice strategies identifying hybrids urge their consideration all future

Most coral reef studies focus on scleractinian (stony) corals to indicate condition, but there are other prominent assemblages that play a role in ecosystem structure and function. In Puerto Rico these include fish, gorgonians, sponges. The U.S. Environmental Protection Agency conducted unique surveys of communities across the southern coast included simultaneous measurement all four assemblages. Evaluating results from community perspective demands endpoints for assemblages, so patterns were explored by probabilistic clustering measured variables with Bayesian networks. found have stronger associations within than between taxa, unsupervised learning identified three cross-taxa relationships potential ecological significance. Clusters each assemblage constructed using an expectation-maximization algorithm created factor node jointly characterizing density, size, diversity individuals taxon. clusters characterized variables, taxa examined, such as stony fish variables. Each nodes then used create set meta-factor further summarized aggregate monitoring taxa. Once identified, taxon-specific meta-clusters represent can be examined regional or site-specific basis better understand risk assessment, management delivery services.

The evolutionary history of the Caribbean candelabrum octocorals from genus Eunicea (Plexauridae: Octocorallia) remains unknown despite their high diversity and abundance in reef environments. Understanding relationships between within species is critical to accurately measuring group diversity. Furthermore, this has a potential for cryptic new species, particularly given rich morphological variability. Conventional molecular markers, however, have not provided precise positioning inside genus. Here, we provide first phylogenomic reconstruction these employing NextRAD, reduced-representation sequencing technique, generate thousands SNPs. We include 15 morphospecies sampled valid throughout Caribbean. At large, phylogeny well supported resolved. In total, 13 species-level clades are discernible, including two lineages with demonstrated genetic variation that considered described as criptica sp. nov. E. colombiensis nov., both previously assigned clavigera second “thick morphotype”, thereby increasing group. magnitude essential directing conservation initiatives clarifying biological processes ecosystems.

Coral reefs are biodiversity hotspots, where new species continue to be discovered. Stylophora pistillata, a depth-generalist coral, is widely distributed throughout the Indo-Pacific and has long been considered poster child for phenotypic plasticity. It occupies wide range of reef habitats exhibits myriad gross morphologies. Here, we used reduced representation genome sequencing (nextRAD) assess genetic structure adults recruits S. pistillata across shallow mesophotic populations in northern Red Sea (Gulf Aqaba). Across analytical approaches, observed complex with at least four genetically divergent lineages occurring sympatrically little no admixture structured by depth. Morphological physiological differences previously documented suggest that long-considered ecological opportunism may, fact, have basis. Assessment both adult colonies within each also revealed prevalence local recruitment structuring eight-kilometer section Israeli coastline. Overall, patterns confirm presence undescribed diversity this model organism coral physiology corroborate broader pattern extensive scleractinian corals.

The conservation and management of coral reef ecosystems will benefit from accurate assessments reef-building species diversity. However, the true diversity corals may be obfuscated by cryptic yet genetically distinct groups, which are likely more pervasive than currently recognised. Here, we investigate prevalence groups assess evidence for their permeability to gene flow (hybridisation) via a structured literature review genomic studies. Using reproducible criteria detect genetic that sympatric, find 68% nominal represented in population studies show comprising partially reproductively isolated these often linked flow. Cryptic frequently segregate environment, especially depth, differ phenotypic characteristics including resilience heat stress. This hidden biodiversity creates challenges restoration planning not well appreciated, hiding declines, biasing estimates species' breadth, overestimating stressors, yielding uncertainty evolutionary dynamics inferred past studies, implying reproductive barriers limit mating between local translocated corals. Incorporating expectation taxa with incomplete boundaries encountered is critical long-term success programs. Studying phenomena detail directly goals. Thus, recommendations best practice strategies identifying hybridisation. In addition, present an untapped resource studying speciation could provide rich opportunities collaboration among biologists fill key knowledge gaps relevant restoration.
