“…Marine coastal soft-bottoms are particularly affected by invasive habitat-forming plants (Neira et al 2005). Among seaweeds, Caulerpales, thanks to their stoloniferous structure, may develop on all kind of substrate (Meinesz et al 1993;Infantes et al 2010) and they are responsible for worrying invasive events worldwide Glardon et al 2008). Caulerpa taxifolia (Vahl) C. Agardh colonization on soft bottoms have been widely investigated, and deep modifications in ecosystems related to its role of engineering species have been emphasized (McKinnon et al 2009;Byers et al 2010).…”

Effects of Caulerpa racemosa invasion on soft-bottom assemblages in the Western Mediterranean Sea

The present study aimed at evaluating the effects of Caulerpa racemosa var. cylindracea spread on Mediterranean soft-bottom assemblages. The benthic assemblages colonized by C. racemosa were compared with non invaded assemblages at multiple spatial scales. In addition, a manipulative experiment has been conducted over a one-year period in order to compare the structure of native assemblages invaded by the alga with others where the alga has been manually removed and others that were not invaded. Results of both studies showed that Mediterranean soft-bottom assemblages invaded by C. racemosa differed from non invaded ones in terms of species composition, abundance and patterns of spatial variability. Moreover, in areas cleaned out from the alga, the benthic assemblages begin to recover their structure and after one year they get more similar to the assemblages observed in non invaded areas. The present paper, taking into account different aspects of C. racemosa invasion in Mediterranean soft bottoms, highlighted that the observed increase in alpha diversity did not correspond to an increase in the overall diversity of the studied system. Infact, the loss of beta diversity in invaded sites, together with the spread of species typical of vegetated habitats, may contribute to a homogenization of the Mediterranean coastal system. Furthermore, a possible role of ecosystem engineer for C. racemosa can be hypothesized.

“…donde se registró por primera vez en mayo de 2001 (Lapointe et al, 2005). Este taxón invasivo también ha sido referido como C. brachypus Harvey (Trowbridge, 2004;Walters et al, 2006;Glardon et al, 2008). Sin embargo, cuando los autores (Jacoby et al, 2004;Banks et al, 2005) presentaron fotografías es claro que la especie invasora pertenece a C. brachypus f. parvifolia, y lo mismo sería para los registros de las Antillas Mayores y Antillas Menores dados por Littler y Littler (2000).…”

Autor para la correspondencia: jespino@ecosur.mxResumen: Veintitrés taxones de Caulerpaceae (14 especies, 3 variedades y 6 formas) se encontraron en 70 sitios a lo largo de las costas de la península de Yucatán, México. La macroalga invasora C. brachypus f. parvifolia se reporta por primera vez en Quintana Roo. El análisis cualitativo de clasifi cación jerárquica aglomerativa ("clustering") mostró ausencia de agrupamientos de sitios representativos de las costas del Caribe mexicano y del Golfo de México, en contraste con otros estudios que han reportado diferencias a ambos lados de la península de Yucatán, con base a la presencia de otros grupos de la biota marina. Caulerpa cupressoides, C. prolifera y C. verticillata fueron las especies con más registros (en 30, 23 y 21 sitios, respectivamente), mientras que C. brachypus, C. lanuginosa, C. microphysa y C. webbiana fueron las menos comunes, con un registro cada especie. Palabras clave: Caulerpa, Caribe mexicano, Golfo de México, macroalgas invasoras, Quintana Roo.Abstract: Twenty-three taxa of Caulerpaceae (14 species, 3 varieties, and 6 forms) were found in 70 sites along the coast of the Yucatan peninsula, Mexico. The invasive macroalgae C. brachypus f. parvifolia is reported for the fi rst time in Quintana Roo, Mexico. A hierarchical agglomerative clustering analysis showed the nonexistence of sites grouping at both sides of the Yucatan peninsula, in contrast with other studies that have reported differences at both sides of the peninsula based on the presence of other groups of the marine biota. Caulerpa cupressoides, C. prolifera, and C. verticillata were the species having more records (in 30, 23, and 21 sites, respectively), while C. brachypus, C. lanuginosa, C. microphysa, and C. webbiana were among the less common species, with one record each species.

“…Los estolones que sobreviven en invierno tienden a establecerse y restaurar la colonia (Glardon et al 2005). Además del estolón, los rizoides se consideran importantes ya que facilitan la colonización, incluso si es un fragmento pequeño del estolón (Khou et al 2007 En la zona de estudio se aprecian dos etapas para C. paspaloides var.…”

Demography of Caulerpa paspaloides var. wudermanni (Bryopsidales: Caulerpaceae) in the coastal zone of Campeche, México. The subaquatic vegetation of Los Petenes, Campeche, Mexico, stands out due to its considerable floristic diversity, composed of a great variety of sea grasses and several species of the genus Caulerpa sp. This is a genus of ecological relevance, with the invasive species in the Mediterranean, with negative impact on several native sub-aquatic plants; nevertheless, little is known about the demography and population dynamics of Caulerpa species and their contribution to food webs. Thus the main objective of this study was to describe the demographics of Caulerpa paspaloides var. wudermanni, using the number of stolons, complete and incomplete fronds, the diameter of the stolons and the biomass. The information was used to determine the growth rate (λ) of this species. The study was conducted in the Biosphere Reserve of Los Petenes, which is located in the Northwest of the state of Campeche. The submerged aquatic vegetation (SAV) in the Petenes Biosphere consists of monospecific and mixed populations of seagrass species (Thalassia testudinum, Halodule wrightii and Syringodium filiforme). Although chlorophytes, brown algae and red algae, are fundamental elements in the specific composition of the SAV in Petenes, several species of Caulerpa are prominent because of their coverage and abundance. In May and June of 2010, significant differences in the quantity of stolons, their diameter, incomplete and complete fronds, and the size of the stolons and rhizomes, were observed. In 2010, the finite population growth rate (λ) was 2.38±0.1571 for individuals and 1.20±0.1356 for the population, and in 2011 the values of λ were 1.80±0.3608 and 1.35±0.1571, respectively. From these results it can be concluded that the population is growing; however, growth is controlled by biotic and abiotic factors. Despite there was no apparent threat, we suggest continuing the demographic studies of C. paspaloides var. wurdemannii, as well as of other species of the same genus, not only to detect invasion or explosive growth, but also their presence indicated low oxygen levels and high sulphates.
