Non-geniculate coralline red algae are very common along the Brazilian coast occurring in a wide variety of ecosystems. Ecological surveys of Ilha Grande Bay have shown the importance of these algae in structuring benthic rocky reef environments and in their structural processes. The aim of this research was to identify the species of non-geniculate coralline red algae commonly present in the shallow rocky areas of Ilha Grande Bay, Brazil. Based on morphological and anatomical observations, three species of non-geniculate coralline algae are commonly present in the area: Lithophyllum corallinae, L. stictaeforme and Hydrolithon reinboldii. Here we provide descriptions of these species and provide a key to their identification. This study represents the first record of H. reinboldii from Brazil.

Ecological Implications

This work presents a detailed morphoanatomical study of crustose coralline algae species from the northeastern Brazilian coast, in the north of Bahia state. Nine species have been recognized: Sporolithon episporum, Lithophyllum stictaeforme, Spongites yendoi, Spongites sp., Mesophyllum erubescens, Phymatolithon masonianum, Phymatolithon calcareum, Lithothamnion crispatum and Lithothamnion brasiliense. Phymatolithon masonianum and Phymatolithon calcareum constitute the first record of these species for the northern coast of Brazil. An identification key, as well as descriptions, illustrations, comparisons with related taxa, and geographical distributions for Brazil as well as global geographic distributions are presented. Additionally, some ecological implications are discussed focusing the need of more studies about this neglected group of coralline red algae.

We provide here the first assessment of the composition, abundance and distribution of rocky reef fishes of Itaipu Sound, Rio de Janeiro, off the southeastern Brazilian coast. Monthly visual censuses, benthic quadrats and chain link transects were conducted over one year on rocky reefs at three islands (Menina, Mãe and Pai). A total of 2466 individual fish, belonging to 29 families and 42 species were recorded. The most abundant fish species were Parablennius pilicornis, Haemulon steindachneri, Orthopristis ruber and Diplodus argenteus. Sheltered and complex habitats showed the most abundant and diverse fish populations. There was a major significant separation between sampling sites and a secondary seasonal pattern. The three sites showed similar fish communities with locally structured environmental gradients according to their inherent habitat characteristics.

A taxonomic reassessment of coralline algae (Corallinales, Rhodophyta) associated with reef environments in the Abrolhos Bank, northeastern Brazil, was developed based on extensive historical samples dating from 1999–2009 and a critical evaluation of type material. Our goal was to update the taxonomic status of the main nongeniculate coral reef-forming species. Our results show that four species are the main contributors to the living cover of coral reefs in the Abrolhos Bank: Lithophyllum stictaeforme, Neogoniolithon atlanticum sp. nov., Porolithon pachydermum and Spongites fructiculosus. Comparison of the type material to modern collections has shown that Lithophyllum congestum is a heterotypic synonym of L. stictaeforme. However, L. stictaeforme and P. pachydermum were the most abundant species at the studied sites, a finding consistent with other coral reefs in the region. This is the first record of S. fructiculosus in the southwestern Atlantic. This review provides the baseline data needed for the monitoring and management of the southernmost limits of coral reefs in the western Atlantic Ocean.

<p><strong>S</strong>tomatopods are a small group of marine and estuarine crustaceans that inhabit several marine ecosystems including deep, shallow waters, and intertidal zones. Six species from five families have been reported from the Park. We add <em>Coronida glasselli</em> Manning, 1976 from rocky reef environments at Isla del Coco. In the Eastern Tropical Pacific the species was reported only from Isla Gorgona, Colombia.

Barcode Gap

Coralline red algae demonstrate phenotypic plasticity related to environmental factors, rendering their identification difficult. The cox2-3 spacer is a mitochondrial marker widely used for phylogeographic studies and discrimination between closely related species in red algae; however, cox2-3 spacer sequence data for coralline algae are still limited. In this study we substantially increase the number of cox2-3 spacer sequences available for coralline algae, exploring their usefulness for different types of molecular investigations in coralline algae (DNA barcoding and phylogeography), with emphasis on rhodolith-forming species. Specimens from North Atlantic Europe, the Caribbean region and the Gulf of California (Mexico) were sequenced and two datasets were built, one for the subfamily Lithophylloideae and one for the Melobesioideae. Our results suggest the utility of cox2-3 spacer as barcoding marker for coralline algae with a slight variation in the barcode gap depending in the way gaps in the alignment are treated. Analyses on both datasets found a barcode gap or separation between intra and interspecific divergence (p distance and ABGD analysis) while some inconsistencies were evident when the results were compared with morphology-based classification. Using the cox2-3 spacer region, the morphospecies Lithophyllum margaritae from the Gulf of California revealed the existence of two well-supported clades, with the possibility of respectively five and two additional species; haplotype networks for Phymatolithon calcareum and P. purpureum revealed similar patterns when Mediterranean and NW Europe specimens were analysed, and P. calcareum was shown to consist of a single population in NW Europe. Based on our analyses the marker cox2-3 spacer has strong potential applications for studies of phylogeography and DNA barcoding in coralline algae after understanding its variation.

Main Bank

A small (100,000 m²) rhodolith bank located at the Arvoredo Marine Biological Reserve (Santa Catarina, Brazil) has been surveyed to determine the main bank components, the community structure, and carbonate production rates. Data from five photographic transects perpendicular to Arvoredo Island shore were complemented with sediment samples and shallow cores, all collected by scuba diving. The main bank component is the unattached, nongeniculate, coralline red algae Lithophyllum sp., used as substrate by the zoanthid Zoanthus sp. Percentage cover of living and dead coralline algae, zoanthids and sediment patches account for nearly 98% of the investigated area. Classification and ordination of samples showed that differences in the proportion of live and dead thalli of Lithophyllum sp. determine the relative abundances of zoanthids. Results also indicate that similarity of samples is high and community gradients are subtle. Significant differences in percentage cover along transects are concentrated in the central portion of the bank. Low carbonate content of sediments from deeper samples suggests low rates of recruitment and dispersal of coralline algae via fragmentation. However, carbonate production of Lithophyllum sp ranging from 55-136.3 g m-2 yr-1 agrees with production rates reported for other temperate settings. In the long run, rhodolith density at Arvoredo Is. is likely to be dependent upon random dispersal of spores and/or fragments from other source areas.
