University of Lausanne, Switzerland A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in the Department of Biology in the College of Arts and Sciences at the University of Central Florida Orlando, Florida Spring Term 2006 ABSTRACT Invasions of exotic species are one of the primary causes of biodiversity loss on our planet (National Research Council 1995). In the marine environment, all habitat types including estuaries, coral reefs, mud flats, and rocky intertidal shorelines have been impacted (e.g. Bertness et al. 2001). Recently, the topic of invasive species has caught the public’s attention. In particular, there is worldwide concern about the aquarium strain of the green alga Caulerpa taxifolia (Vahl) C. Agardh that was introduced to the Mediterranean Sea in 1984 from the Monaco Oceanographic Museum. -
E-Commerce and Caulerpa: Unregulated Dispersal of Invasive
RESEARCH COMMUNICATIONS RESEARCH COMMUNICATIONS E-commerce and Caulerpa: unregulated 75 dispersal of invasive species Linda J Walters1*, Katherine R Brown1, Wytze T Stam2, and Jeanine L Olsen2 Professional aquarists and hobbyists are thought to be the source of invasions of the aquarium strain of the green macroalga Caulerpa taxifolia in the Mediterranean, southern California, and Australia. The US Department of Agriculture, Animal and Plant Health Inspection Service (USDA–APHIS) restricted interstate commerce and importation of the Mediterranean clone of C taxifolia prior to the California invasion and is cur- rently deciding if it should strengthen regulation of this genus as more species of Caulerpa are being described as invasive. Here we document the importance of e-commerce as a mode of dispersal for many species of Caulerpa in the United States. We purchased Caulerpa from 30 internet retailers and 60 internet auction sites representing 25 states and Great Britain. Twelve different Caulerpa species were confirmed using DNA sequenc- ing. Only 10.6% of sellers provided the correct genus and species names with their shipments. Thirty purchases of “live rock” provided four species of Caulerpa, as well as 53 additional marine species. Our results confirm the extensive e-commerce availability of this invasive genus and its high dispersal potential via postal services and hobbyists. We recommend that both eBay and the USDA maximize regulation of Caulerpa.

Salinity, temperature, nutrients, and light are considered essential parameters to explain growth and dis- tribution of macroalgal assemblages in coastal zones. Goals. In order to evaluate the effect of salinity on the growth properties of Caulerpa sertularioides, we conducted this study under laboratory conditions to find out how salinity affects the distribution of this species in coastal tropical environments. Methods. Five ranges of salinity were used for the experi- ments (15, 20, 25, 30, and 35 ppt), simulating in situ salinity conditions on the south Pacific Coast of Colombia. The culture was grown in an environmental chamber with controlled temperature and illumination, and a 12:12 photoperiod. The following growth variables were measured weekly: wet biomass, stolon length (cm), number of new fronds and rhizomes. In the experimental cultures, growth (increase in wet biomass and stolon length) was calculated as the relative growth rate (RGR), expressed as a percentage of daily growth. -

Algae Sheets-Invasive Elsewhere
ALGAE: NATIVE Caulerpa sertularioides (Gmel.) Howe 1905 C. sertularioides is a small delicate green alga found only in Oahu and Kauai. This species closely resembles C. taxifolia, the invasive killer weed of the Mediterranean. Division: Chlorophyta Class: Ulvophyceae Order: Bryopsidales Family: Caulerpaceae Genus: Caulerpa © L.Preskitt 2001 IDENTIFYING FEATURES HABITAT DESCRIPTION This delicate plant is usually found in warm, quiet waters in tide pools or on sandy, calm reef flats. It Branches, feather-like, flattened, and upright, 3 - 5 cm anchors to sandy bottoms or coral rubble by the creep- high, rising from a creeping stolon (runner), 1 - 2mm in ing rhizoids. diameter, anchored by rhizoids to the substrate. Branchlets oppositely attached to midrib, flattened, slightly curved upwards and tapered at both base and tip. Midrib is slightly flattened, appearing oval in cross-section. This species resembles another native Hawaiian Caulerpa species, C. taxifolia. C. sertularioides is more delicate and the branchlets are rounded, compared to the flattened branchlets of C. taxifolia. The rising branches are also more rounded toward apices, com- pared to the more angular, squared-off branches of C. taxifolia. © L.Preskitt 2001 COLOR Light green to yellow green. STRUCTURAL FEATURES Thallus non-septate, coenocytic, traversed by trabeculae, which are extensions of cell wall; reporduction vegeta- tive and sexual, latter anisogamous. Gametes liberated throug papillae that develop on frond or occasionally on frond. © Botany, University of Hawaii at Manoa 2001 A-45 Caulerpa sertularioides DISTRIBUTION REFERENCES HAWAII Abbott, I.A., 2001, unpublished manuscript.

A New Taxonomic Survey of Caulerpa Lamouroux Species (Chlorophyta, Caulerpales) in the Southern Coasts of Iran
American Scientific Research Journal for Engineering, Technology, and Sciences (ASRJETS) ISSN (Print) 2313-4410, ISSN (Online) 2313-4402 © Global Society of Scientific Research and Researchers http://asrjetsjournal.org/ A New Taxonomic Survey of Caulerpa Lamouroux Species (Chlorophyta, Caulerpales) in the Southern Coasts of Iran Masoumeh Shamsa*, Nahid Ghaed Aminib aNajaf Abad College of Science and Technology, Najaf Abad, Islamic Republic of Iran bDepartment of Biology,Payame Noor University of Isfahan, Isfahan, Iran aEmail: [email protected] Abstract The genus Caulerpa (Chlorophyta), a coenocytic marine macroalgae, consists of about 75 species of tropical to subtropical siphonous green algae. Caulerpa species inhabit the intertidal and shallow subtidal region along the coast of Iraniansouth. The aim of this research was the taxonomic and florestic study of the genus Caulerpa in the southern coast of Iran due to the abundance of this genus, as well as the importance of this genus in terms of food and especially its antioxidant and anti-bacterial properties. In a survey conducted from Febriary 2015 to January 2016, we found seven species as Caulerpa cupressoides (vahl.) C. Agardh, C. peltata (Lamouroux), C. racemose (Forskkal) J. Agardh, C. fastigiataMontagne, C. scalpelliformis (Turner) C. Agardh, C. sertularioides (S.G.Gemelin.) Howe;C. taxifolia (Vahl) C. Agardh. In conclusion, a little study is known about the diversity of this genus along the coast of Iran, and this study can at least partly be attributed to the complex systematics of the genus, which is characterized by considerable morphological plasticity. Keywords: Caulerpa; Distribution; Iran; Taxonomy. 1. Introduction Caulerpa (Chlorophyta, Caulerpales) or Briopsidophyceae [1] is one of the most distinctive algal genera, identifiable solely on the basis of its habit (growth form) and internal morphology [2]. -

The Nature of Macroalgae and Their Interactions on Reefs Mark M
The Nature of Macroalgae and Their Interactions on Reefs Mark M. Littler and Diane S. Littler ABSTRACT. What was known about tropical reef algae prior to the use of scuba came largely from dredging studies or drift collections, which usually resulted in highly mutilated specimens and questionable habitat data. Scuba allows a precise determination of ecological conditions and permits in situ photography, two techniques our group has relied on during the past three decades for quan- titative studies and field guide production. A goal of this review is to familiarize the scientific diving community with the kinds and roles of algae on tropical reefs, with the hope that seaweeds will be utilized more fully as tools for addressing important ecological questions. ecause of the rapid degradation of tropical reefs worldwide, it is imperative that the role and diversity of macroalgae be studied in a timely, efficient, and scientifi- Bcally verifiable manner. It is of paramount importance to characterize the world’s coral reef environments and to understand the responses of foundation species. The fleshy macroalgal forms are the food of herbivores, and only become abundant when their pro- duction rate exceeds the capacity of herbivores to consume them. On healthy oligotrophic coral reefs, even very low nutrient increases may shift relative dominance from corals (Cnidaria) to macroalgae by both stimulating macroalgal production and inhibiting cor- als. As a result, frondose macroalgae are generally recognized as harmful to the longevity of coral reefs due to the link between excessive blooms and coastal eutrophication. Reef plant complexity has evolved along very different evolutionary lines.
