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. -

Abstract Background: Among metazoans, retention of functional diet-derived chloroplasts (kleptoplasty) is known only from the sea slug taxon Sacoglossa (Gastropoda: Opisthobranchia). Intracellular maintenance of plastids in the slug's digestive epithelium has long attracted interest given its implications for understanding the evolution of endosymbiosis. However, photosynthetic ability varies widely among sacoglossans; some species have no plastid retention while others survive for months solely on photosynthesis. We present a molecular phylogenetic hypothesis for the Sacoglossa and a survey of kleptoplasty from representatives of all major clades. We sought to quantify variation in photosynthetic ability among lineages, identify phylogenetic origins of plastid retention, and assess whether kleptoplasty was a key character in the radiation of the Sacoglossa. -
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.

Fingerprinting Marine Macrophytes in Blue Carbon Habitats
Fingerprinting Marine Macrophytes in Blue Carbon Habitats Thesis by Alejandra Ortega In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in Bioscience King Abdullah University of Science and Technology Thuwal, Kingdom of Saudi Arabia November, 2019 2 EXAMINATION COMMITTEE PAGE The thesis of Alejandra Ortega is approved by the examination committee. Committee Chairperson and Thesis Supervisor: Prof. Carlos M. Duarte Committee Members: Prof. Mark Tester, Prof. Takashi Gojobori, and Prof. Hugo de Boer [External] 3 © November, 2019 Alejandra Ortega All Rights Reserved 4 ABSTRACT Fingerprinting Marine Macrophytes in Blue Carbon Habitats Alejandra Ortega Seagrass, mangrove, saltmarshes and macroalgae - the coastal vegetated habitats, offer a promising nature-based solution to climate change mitigation, as they sequester carbon in their living biomass and in marine sediments. Estimation of the macrophyte organic carbon contribution to coastal sediments is key for understanding the sources of blue carbon sequestration, and for establishing adequate conservation strategies. Nevertheless, identification of marine macrophytes has been challenging and current estimations are uncertain. In this dissertation, time- and cost-efficient DNA-based methods were used to fingerprint marine macrophytes and estimate their contribution to the organic pool accumulated in blue carbon habitats. First, a suitable short-length DNA barcode from the universal 18S gene was chosen among six barcoding regions tested, as it successfully recovered degraded DNA from sediment samples and fingerprinted marine macrophyte taxa. Second, an experiment was performed to test whether the abundance of eDNA represents the content of organic carbon within the macrophytes; results supported this notion, indicating a positive correlation (R2 = 0.85) between eDNA and organic carbon. -

This represents the frst inventory encompass- ing the three major macroalgal classes (Phaeophyceae, Florideophyceae and Ulvophyceae) for the little-known Malagasy marine fora. Combining morphological and DNA-based approaches, we report from our collection a total of 110 species from northern Madagas- car, including 30 species of Phaeophyceae, 50 Florideophyceae and 30 Ulvophyceae. Bar- coding of the chloroplast-encoded rbcL gene was used for the three algal classes, in addi- tion to tufA for the Ulvophyceae. This study signifcantly increases our knowledge of the Malagasy marine biodiversity while augmenting the rbcL and tufA algal reference libraries for DNA barcoding. These eforts resulted in a total of 72 new species records for Mada- gascar. Combining our own data with the literature, we also provide an updated catalogue of 442 taxa of marine benthic -

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. -
