“…Thus, MOTU 1 is restricted to the Warm Temperate Northwest Atlantic Province; MOTUs 2, 3, and 4 to the North Brazil Shelf Province; MOTU 5 to the Tropical Southwestern Atlantic Province; and MOTUs 6 and 7 to the Warm Temperate Southwestern Atlantic Province. Furthermore, phylogeographic and population genetic studies on other marine invertebrates have also matched these biogeographic divisions (corals – Peluso et al, 2018 ; crustaceans – Mattos, Seixas & Paiva, 2019 ), suggesting dominant phylogeographic discontinuities in the region pervasive across multiple and diverse taxa.…”

The polychaete genus Laeonereis (Annelida, Nereididae) occurs over a broad geographic range and extends nearly across the entire Atlantic coast of America, from the USA to Uruguay. Despite the research efforts to clarify its diversity and systematics, mostly by morphological and ecological evidence, there is still uncertainty, mainly concerning the species Laeonereis culveri, which constitutes an old and notorious case of taxonomic ambiguity. Here, we revised the molecular diversity and distribution of Laeonereis species based on a multi-locus approach, including DNA sequence analyses of partial segments of the cytochrome c oxidase subunit I (COI), 16S rRNA, and 28S rRNA genes. We examined Laeonereis specimens collected from 26 sites along the American Atlantic coast from Massachusetts (USA) to Mar del Plata (Argentina). Although no comprehensive morphological examination was performed between different populations, the COI barcodes revealed seven highly divergent MOTUs, with a mean K2P genetic distance of 16.9% (from 6.8% to 21.9%), which was confirmed through four clustering algorithms. All MOTUs were geographically segregated, except for MOTUs 6 and 7 from southeastern Brazil, which presented partially overlapping ranges between Rio de Janeiro and São Paulo coast. Sequence data obtained from 16S rRNA and 28S rRNA markers supported the same MOTU delimitation and geographic segregation as those of COI, providing further evidence for the existence of seven deeply divergent lineages within the genus. The extent of genetic divergence between MOTUs observed in our study fits comfortably within the range reported for species of polychaetes, including Nereididae, thus providing a strong indication that they might constitute separate species. These results may therefore pave the way for integrative taxonomic studies, aiming to clarify the taxonomic status of the Laeonereis MOTUs herein reported.

“…The phylogeographic patterns observed for L. sanguineus are consistent with those reported for other marine invertebrates in the southwestern Atlantic. For example, the polychaete Perinereis ponteni and the crustaceans Uca maracoani and Ocypode quadrata also present high haplotypic diversity and low to moderate population structure (Mattos et al 2019;Paiva et al 2019;Mendes et al 2022).…”

Lineus sanguineus (Rathke, 1799) is a cosmopolitan species commonly found on fouling fauna along rocky shores. Along with the larval capability of the pilidium larvae in heteronemerteans, this species can reproduce asexually by fissiparity. The present study utilized a phylogeographic approach combined with Ecological Niche Modeling analysis to evaluate L. sanguineus populations along the Brazilian coast. We used sequences from two mtDNA regions, 16S ribosomal RNA (16SrRNA) and cytochrome c oxidase subunit 1 (COI), and one nuclear region, Internal Transcribed Spacer 1 (ITS-1), of 85 specimens sampled in nine locations. Genetic diversity analysis showed more ITS-1 marker diversity, evidenced by augmented intrapopulation diversity values. There was no clear geographic pattern, and the AMOVA analysis revealed low to moderate genetic structuring and high connectivity between localities, with most of the genetic variation contained within populations (mtDNA AMOVA, FST=0.18, ITS FST=0.33). The pairwise FST results indicate high genetic structuring between the Northeast and localities in the South and Southeast of Atlantic costal zone. This pattern suggests that Brazilian oceanic currents play an important role in species connectivity. The paleodistribution pattern demonstrated that probably the colonization occured from the South to the Northeast of the continent. These results reinforce that sexual reproduction and larval dispersion play a vital role in the connectivity of these Southwest Atlantic populations and that oceanographic currents facilitate these processes.

“…Because O. quadrata has an indirect development with a long-lived larval stage and populations sharing haplotypes over ∼7,000 km (Mattos et al, 2019) is expected that not only coastal modification and beach characteristic will influence population densities, but also oceanic variables. Although sandy beaches occupy about one-third of ice-free coastline (Luijendijk et al, 2018), large scale (i.e., regional and continental) oceanic environmental drivers of macrofauna distribution have only been investigated quite recently (Defeo et al, 2017).…”

Low Densities of the Ghost Crab Ocypode quadrata Related to Large Scale Human Modification of Sandy Shores

Sandy beaches are the most common ecosystems of coastal regions and provide direct and indirect essential services for millions of people, such as coastal protection, fishing, tourism, and recreational activities. However, the natural habitats of sandy shores are being modified at rates never experienced before, making beaches key monitoring sites of marine ecosystems worldwide. The ghost crab species Ocypode quadrata is the most conspicuous crustacean of sandy beaches along the Western Atlantic coast and has been successfully used as an indicator of anthropogenic disturbance and environmental variability. To investigate the potential role of a “triple whammy” [(1) urbanization; (2) use of resources; (3) decreasing resilience] on the most common bioindicator of sandy shores, we compiled a dataset including 214 records of burrows density from 94 microtidal sandy beach sectors covering a range of over 65° of latitude. The response of burrows density to synergetic effects of human modification of natural systems and environmental changes was investigated using linear models. We used the cumulative Human Modification (HMc) index, a standardized geographic projection of changes of natural systems, as a predictor of urbanization, industrialization and use of resources. The predictor wave energy, tidal range and temperature (sea surface and air) were included as potential effects of climate changes. Literature review showed records mainly concentrated at sub-tropical and temperate regions. HMc values were clearly negatively related to burrows density, thereby supporting an effect of modification of natural habitat at large spatial scale. Sea surface temperature and air temperature were positive related with density and the lack of a general pattern of the relationship between burrows density, interactions between wave energy and tide range, supported unclear patterns reported at regional scales. Finally, we argue that ghost crabs are valuable targets for protection actions on sandy beaches that can benefit coexisting species and provide natural habitat conservation.
