ABSTRACT
The presence of tetrahedrally divided tatrasporangia in Ceramium bisporum Ballantine is reported for the first time. The plant was found as epiphytic on calcareous Halimeda tuna in coral reef environment in Caribbean Colombia. The taxon represents a new record for the country.
Keywords: Caribbean, Ceramium bisporum, tetrasporangia.
RESUMEN
Se reporta por primera vez la presencia de tetrasporangios divididos tetrahedricamente para la especie Ceramium bisporum. El alga fue encontrada epífita del alga calcárea Halimeda tuna en arrecifes coralinos en el Caribe colombiano. El taxón representa un nuevo registro para el país.
Palabras clave: Caribe, Ceramium bisporum, tetrasporangios.
Ceramium bisporum Ballantine was originally described as a diminutive deep-water species offshore Puerto Rico and the United States Virgin islands (Ballantine, 1990). The species is characterized by an extensive prostrate system attached to calcareous substrate, short erect exes, ill-developed nodal cortication, and production of bisporangia. Since its description, C. bisporum has been reported only once, in the Mediterranean Sea (Sartoni y Boddi, 2002). Here we report the presence of the species in coral reef habitat in San Andres Island, Caribbean Colombia. We observed fertile thalli bearing tetrahedrally divided tetrasporangia. This is the first report of the taxon for Colombia, and the first observation of tetrasporangia for the species. Specimens were collected by scuba diving during a macroalgal survey in Wild Life, San Andres Island, at a depth of 12.5 m.
Algae were preserved in 5 % formalin in seawater. In the laboratory, plants were carefully removed from the substrate, stained with 1 % aniline blue and observed with a BX51 Olympus microscope (Olympus, Tokyo, Japan). Photographs were taken with a digital camera Moticam 2.0 (Motic, Hong Kong) mounted on the microscope.
Ceramium bisporum Ballantine
Type locality: Grappler Bank, offshore Puerto Rico, dredged 55-90 m.
Plants diminute, epiphytic on Halimeda tuna. Thalli prostrate and erect (Fig. 1), attached to the substrate by rhizoids. Erect axes to 1.4 mm tall. Axial cells in prostrate axes 25 µm diameter, 75-90 µm long. Nodes scarcely developed, formed by a single band of cells, axial cell 30 um diameter and 65 µm long, node 40 µm diameter, 22 µm long, formed by four rectangular periaxial cells, wider than long 7-7.5 µm long x 10-12 µm wide (Fig. 2); tetrasporangia tetrahedrally divided, generally one, sometimes two per node, 55 µm diameter, not covered by nodal cells (Figs. 3, 4). Gametophytes were not observed. Specimens observed: NRD 055, NRD 142, wild life (12° 30' 30, 77" N - 81° 43' 45 53" W), San Andrés Island, 2/IX/ 2012; collected by hand, at a depth of 12.5 m.
Remarks: Ceramium bisporum is characterized by its small size, creeping nature, and minimally developed nodal cortication (Ballantine, 1990). In the Western Atlantic, there are six Ceramium species with nodal cortication similar to C. bisporum: C. Affine Setchell and Gardner, C. Cimbricumf. Flaccidum(Petersen) Furnari and Serio, C. Codii (Richards) Mazoyer, C. Comptum Borgesen, C. Leptozonum Howe, and C. Reptans Cho and Fredericq. However, these species differ from our specimen in the following characteristics (Table 1): C. Affine has a node formed by 2-3 cortical bands (Setchell and Gardner, 1930), while our specimen has only one band (Fig. 2); C. Cimbricum f. Flaccidum and C. Codii have tetrasporangia partially covered by short cortical cells (Setchell and Gardner, 1930; Schneider and Searles, 1990: p. 379, as C. fastigiatum f. Flaccidum; Cho and Fredericq, 2006), while in our specimen the tetrasporangia are naked (Figs. 3, 4); C. Comptum has a much larger thallus and axes with a diameter at least twice the size of our specimen (Taylor, 1960), as well as more than four pericentral cells (Borgesen, 1924). C. Leptozonum and C. Reptans also have a greater number of pericentral cells, eight to ten cells longitudinally elongated in C. Leptozonum (Littler et al., 2008), five in C. Reptans (Cho and Fredericq, 2006), compared to just four in our specimen. Our alga is small in size, and while has a total height of 1.2 mm, larger than 1 mm exceptionally large specimens reported by Ballantine (1990), the diameter of the axes, the number of pericentral cells, and the nodal cortication fits the description of Ceramium bisporum. In his original description, Ballantine (1990) reported inflated, two-celled rhizoids. However, for Mediterranean specimens, not inflated, three-celled rhizoids were reported (Sartoni and Boddi, 2002). When we detached the specimen from its substrate, the rhizoids broke (Fig. 1), so we were unable to determine their morphology. However, we found the species on calcareous substrate as did the former records, and Ballantine (1990) emphasized that he could not separate the plant from its substrate without decalcification because the rhizoids adhere very strongly to it, a character we can confirm as well. The presence of bisporangia in the Ceramiaceae has been observed occasionally on several species (Athanasiadis, 1987; Guiry, 1990; L‘Hardy-Halos and Maggs, 1991), and is interpreted to represent an asexual function (Ballantine, 1990). The presence of tetrasporangia in our specimen, collected in a different season than former report in the Caribbean (November vs. August) may indicate a seasonal production of tetrasporangia and bisporangia, as it has been evidenced in Crouania attenuata (C. Agardh) J. Agardh, which produces bisporangia in winter and tetrasporangia in summer (Guiry, 1990). It would be interesting to determine the seasonality of the reproductive stages of Ceramium bisporum in the field.
