“…The type locality (West Indies) of these three different species are remote from that of D. hommersandii. The branch width of D. obtusata from the Atlantic Ocean is much greater than that of D. hommersandii (Wynne, 2011) and the partial rbcL sequence of a D. obtusata specimen from North Carolina clusters with the D. obtusata assemblage (S.-L. Liu, unpublished data), indicating that D. hommersandii differs from D. obtusata from the Atlantic Ocean. Our literature review did not reveal any evidence that D. hommersandii has been described under another name in the past.…”

Members of the Galaxauraceae are all calcified and have a wide distribution from tropical to temperate regions. Of the four genera of Galaxauraceae, only Dichotomaria contains two distinct thallus forms, which are (1) a flattened form with either narrow (e.g. D. marginata) or wide (e.g. D. diesingiana) branches, and (2) a terete form with either slender (e.g. D. papillata) or robust (e.g. D. obtusata) branches. In this study, we present a molecular phylogeny of new Dichotomaria samples from the Indo-Pacific region and describe a new species, D. hommersandii S.L. Liu & S.M. Lin, from South Africa, based on rbcL sequence analysis and morphological evidence. Dichotomaria hommersandii is characterized by a thallus consisting of terete smooth branches (0.5-1.5 mm in diameter), a moniliform branching pattern with constrictions at the nodes, ramification of young branches derived from the damaged terminal regions of the old branches, and cystocarps containing a conspicuous fusion cell. Our phylogenetic analyses indicate that the terete thallus morphology could be the ancestral character state in Dichotomaria.

“…Although P. cervicornis (as L. cervicornis ) has been reported in several sites around the world, many of those reports do not include a morphological description (Suárez , Wynne et al. , Wynne , Tsuda and Walsh ); or the descriptions are for juvenile organisms (Littler and Littler , Dawes and Mathieson ). Thanks to the cultivation of the specimens of Palisada cervicornis in aquaria, we were able to describe the morphology, including for the first time a detailed description of its reproductive structures and other observations allowing us to differentiate this species from other similar species in the region.…”

As marine tropical ecosystems deteriorate and lose biodiversity, their communities are shifting to being dominated by a few species, altering ecosystem's functioning and services. Macroalgae are becoming dominant on coral reefs, and are frequently observed outcompeting corals. Turf algal assemblages are the base of energy flow in these systems and one of the most abundant types of macroalgae on coral reefs, but little is known about their biology and diversity. Through molecular and morphological analyses, we identified the turf-forming species Laurencia cervicornis, and by studying seasonal recruitment and the impact of herbivorous fishes on its abundance, we describe its survival strategy. The molecular analyses used a total of 45 rbcL gene sequences including eight current genera within the Laurencia complex and two new sequences of L. cervicornis and strongly support the new combination of Palisada cervicornis comb. nov. In addition, a detailed morphological characterization including the description of reproductive structures is provided. Palisada cervicornis was seen recruiting in all seasons but was typically in low abundance. Specimens grown on tiles in fish exclosure cages were devoured in less than 4 h when offered to fishes. Even though many species of the Laurencia complex have chemicals that deter herbivory, species within the genus Palisada lack feeding deterrents and thus are highly palatable. We suggest that P. cervicornis is a palatable species that seems to survive in the community by obtaining a size-refuge from herbivory within turf communities.

First Record of Acetabularia myriospora (Polyphysaceae, Chlorophyta) in the Ceará State, Brazil

On rocky shores, macroalgae play an ecological role as organizer of community structures, since they are source of food for many invertebrate species inhabiting their fronds, as well as providing shelter from predators, enhancing environment conditions and reducing water movement. With this in mind, detecting new species on a regional scale is of major importance for biodiversity monitoring and conservation. In the current study, a first record of the seaweed species Acetabularia myriospora was made in the offshore of Ceará state, Brazil. The frequency of occurrence of A. myriospora (1.62%) is considered low whether compared to that of A. calyculus (17.43%). This study is the first record of the species Acetabularia myriospora (Polyphysaceae, Chlorophyta) in the coastline of Ceará state.
