Although important consolidators and settlement inducers of organisms such as corals, echinoderms, molluscs on coral reefs, crustose coralline algae (CCA) have been some the least studied in megadiverse Coral Triangle tropical Indo-Pacific Ocean. CCA were sampled from reefs across different ecological zones Spermonde Archipelago within through diver collections along 10 X 1 m transects deployment Autonomous Reef Monitoring Structures (ARMS). Using DNA sequences psbA, COI-5P, rbcL barcodes,...

:Among the distinctive members of brown algal family Scytosiphonaceae is genus Hydroclathrus, which primarily distinguished by its clathrate (net-like) appearance. despite being seasonal and species poor, a conspicuous floristic component in many tropical to warm temperate coasts. However, compared with other closely related genera, such as Colpomenia Rosenvingea, Hydroclathrus remains poorly known; taxonomy problematic, information on molecular phylogenetic relationships still scarce. We...

Seaweed diseases have been reported in both wild and cultivated seaweed species worldwide. However, reports on tropical are uncommon often focused farmed species. In the Philippines, economically important such as Eucheuma, Kappaphycus, Halymenia. Regarding Halymenia, occurrence of white rot disease has laboratory-reared open sea-outplanted individuals. Here, I report for first time Halymenia durvillei observed wild. While may detrimental effects, hypothesize that subsequent breaking...

Abstract A new and putatively endemic species of Hydroclathrus , rapanuii is described from the geographically isolated Easter Island in southeastern Pacific based on morphological molecular phylogenetic data. It distinguished other by thalli unevenly furrowed thin membranes, angular, block-like plurangial sori. Our analyses indicated that H. closely related to generitype clathratus . We also report morphology phylogeny Chnoospora minima I. elsewhere Indo-Pacific Ocean, noting previously...

The taxonomy of the genus Eucheuma J. Agardh (1847) has long been considered as among most challenging commercially and economically important red seaweeds it exhibits extreme polymorphism highly plastic morphologies (Ganzon-Fortes et al. 2012). Efforts to clarify these were prompted by development a culture technology support growing demand for carrageenans that they produce. Significant changes in classification eucheumatoid species ushered works Doty & Norris (1985), who initiated...

SUMMARY The taxonomy, classification, and phylogenetic relationships of the brown seaweed genus Iyengaria with other members family Scytosiphonaceae remain poorly understood. In this study, we addressed some problems in systematics (taxonomic classification status) position based on our studies generitype stellata from Kuwait South Africa. We confirm that I. is conspecific Colpomenia capensis molecular morpho‐anatomical data species has a disjunct distribution within Indian Ocean. Also,...

Abstract The brown algal family Scytosiphonaceae has recently received considerable attention resulting in the description of several new genera and species. However, members genus Scytosiphon Petalonia remain polyphyletic. By integrating multi-gene phylogenetic data (mitochondrial cox 3 plastid psa A rbc L genes) with their known morpho-anatomies life histories, we herein resurrect Hapterophycus canaliculatus , currently considered a member transfer tenellus to .

Abstract The brown algal genus Acinetospora is characterised by sparsely branched uniseriate filaments, scattered meristematic zones, short laterals (“crampons”) and reproductive organs. morphology life history of the generitype A. crinita have been studied repeatedly, accounts species’ highly varied patterns were assumed to be due presence multiple taxa that reported under this name. Herein, we attempt contribute taxonomy conducting morphological culture studies on 33 samples collected from...

Background and aims – Studies on the diversity of seaweed flora Philippines have waned in past decades, detailed data distribution these economically important resources is missing. We attempt to bridge this gap by providing information diversity, distribution, some aspects ecology a marine biodiversity corridor western Philippines, Balabac Marine Biodiversity Conservation Corridor (BMBCC). Methods In seventeen stations BMBCC, floras were assessed. All seaweeds encountered identified situ,...

SUMMARY Morphological and anatomical evidence is presented to support the taxonomic judgment that Talarodictyon tilesii Endlicher conspecific with Hydroclathrus stephanosorus Kraft in & Abbott. Because former name has nomenclatural priority over latter name, (Endlicher) comb. nov. proposed.

We evaluated the life cycle of Leathesia marina through molecular analyses, culture studies, morphological observations, and ploidy measurements. Macroscopic sporophytes were collected from two localities in Atlantic Patagonia cultured under long-day (LD) short-day (SD) conditions. Molecular identification microscopic macroscopic phases was performed cox3 rbcL genes phylogeny assessed on basis single gene concatenated datasets. Nuclear each phase estimated DNA contents individual nuclei...

SUMMARY Members of the brown algal order Asterocladales are characterized by stellate arrangement its chloroplasts, in which a configuration has protruding central pyrenoid complex. The is represented genus Asterocladon , consists only three species so far. Similar to other small and filamentous seaweeds, studies on remain scant their diversity poorly understood. To fill this gap, we conducted molecular‐assisted taxonomic based seven culture isolates collected from Okinawa Prefecture, Japan...

Étude des Sargassum (Fucales, Phaeophyceae) dans le nord-ouest de Luzon, Philippines au moyen outils la taxonomie moléculaire. La diversité du genre d'algues brunes C.Agardh aux est plus élevée l'océan Pacifique tropical occidental. Cependant, plupart études sur les sont basées morpho-anatomie, et l'hypothèse selon laquelle très diversifié pays n'a jamais été vérifiée base d'informations moléculaires. Étant donné que nombreuses espèces hautement polymorphiques phylogénétiques moléculaires...
