Sargassum kendrickii (Fucales, Phaeophyceae), a new species of subgenus Phyllotrichia from southern Australia
No full textSargassum kendrickii N. Goldberg et Huisman, sp. nov. is described from subtidal habitats in the Esperance region, southern Western Australia. The new species belongs to the subgenus Phyllotrichia and can be distinguished from all previously described species in the morphology of its lateral branches, which are pinnate, alternately arranged, and have serrated margins. Vesicles are absent and receptacles form open clusters in branch axils. The new species is compared to all species of Sargassum subgenus Phyllotrichia worldwide

Marine benthic flora of the Dampier Archipelago, Western Australia
No full textThere is a lack of information regarding the marine benthic flora of northwest Western Australia and a comprehensive flora for the region has never been produced. A checklist of the marine benthic flora of the Dampier Archipelago collected during the Western Australian Museum expeditions of 1998/1999 is presented. This list, however, must be viewed as preliminary, as many of the specimens collected are yet to be identified
New Records and Notes on Hawaiian Marine Benthic Chlorophyta, including Pseudochlorodesmis abbreviata (Gilbert), n. comb. (Udoteaceae) and Cladophora luxurians (Gilbert), n. comb. (Cladophoraceae)
No full textMorphology, taxonomy, and nomenclature of three species of Hawaiian
green algae (Chlorophyta) are examined. Udotea? abbreviata Gilbert is
shown to be incorrectly placed in that genus and more appropriately allied to
Pseudochlorodesmis. The complex nomenclatural relationships of Cladophora tildeniae
Brand in Tilden, Cladophora tildeniae Brand, and Cladophora hawaiiana Tilden
are described, with the latter deemed the appropriate name and Microdietyon
japonicum var. laxum Gilbert regarded as a synonym. An examination of Cladophoropsis
luxurians Gilbert has shown it to have delayed formation of transverse
walls at the bases of lateral branches, a feature not consistent with inclusion in
Cladophoropsis but rather with Cladophora. The new combinations Pseudochlorodesmis
abbreviata (Gilbert) Abbott & Huisman and Cladophora luxurians (Gilbert)
Abbott & Huisman are made, and nine species of marine benthic Chlorophyta
are newly recorded for the Hawaiian Islands

New species, observations, and a list of new records of brown algae (Phaeophyceae) from the Hawaiian Islands
No full textTwo new species of brown algae (Phaeophyceae), Padina moffittiana Abbott et Huisman, sp. nov. and Cutleria irregularis Abbott et Huisman, sp. nov., are described from the Hawaiian Islands (between 19°04′N, 155°35′W and 28°25′N, 178°20′W). In addition, the new combination Cutleria canariensis is proposed for Aglaozonia canariensis. New observations are presented on Nereia intricata Yamada, a species described 67 years ago and known only from its type specimen. New records of a further 14 species are given for the Hawaiian Islands. These 17 taxa bring the total number of species of brown algae recorded for the Hawaiian Islands to 55, an increase of 28%. Of the 15 new records, two are recent ‘accidental’ introductions: Dictyota flabellata (Collins) Setchell et Gardner and Sargassum muticum (Yendo) Fensholt from California. Six records are notable because of their great distances from previously known collections: Nereia intricata Yamada from the Ryukyu Is., Japan; Discosporangium mesarthrocarpum (Meneghini) Hauck, from the Adriatic, Mediterranean, warm Atlantic and southern Australia; Distromium flabellatum Womersley, Spatoglossum macrodontum J. Agardh, and Sporochnus moorei Harvey, from Australia; Desmarestia ligulata (Lightfoot) Lamouroux from temperate and colder waters in the Pacific and Atlantic. A comparison with some Japanese species of Padina confirms that Padina japonica Yamada should be subsumed with Padina sanctae-crucis Børgesen, as proposed earlier
Phylogenetic study of the Nemaliales (Rhodophyta) based on large-subunit ribosomal DNA sequences supports segregation of the Scinaiaceae fam. nov. and resurrection of Dichotomaria Lamarck
No full textGene sequence data have been newly obtained for 18 species in 13 genera of the order Nemaliales (Rhodophyta), allowing for the first time a relatively comprehensive molecular phylogenetic appraisal of the order. The phylogenetic trees generated from these data support the recognition of three families: (i) the Liagoraceae as presently constituted; (ii) a reduced Galaxauraceae includingActinotrichia,Galaxaura (sensu lato), andTricleocarpa; and (iii) a new family, Scinaiaceae, segregated from the Galaxauraceae and including the generaScinaia,Gloiophloea,Nothogenia, and probablyWhidbeyella. The four genera of the Scinaiaceae differ from the newly circumscribed Galaxauraceae in being uncalcified, and having heteromorphic life histories in which the tetrasporophyte is much reduced and filamentous or crustose. This type of life history is found in onlyTricleocarpaof the Galaxauraceae. The results also showGalaxaurato be para/polyphyletic ifActinotrichiaandTricleocarpaare recognized. To remedy this, theGalaxaura marginataspecies complex,Galaxaura diesingiana, andGalaxaura obtusataare removed from the genus and placed in the resurrectedDichotomariaLamarck.Galaxaura marginata, presently thought to be wide-ranging and morphologically variable, is shown to comprise several species. As a consequence,Galaxaura teneraKjellman andBrachycladia australisSonder are removed from the synonymy ofG. marginataand restored as independent species inDichotomariafor South African and Australian isolates, respectively. The Liagoraceae is shown to encompass genera previously placed in the segregate families Nemaliaceae and Dermonemataceae, and the value of the reproductive characters used to define those taxa is discussed.

Eating with an artificial commensal companion
No full textCommensality is defined as "a social group that eats together", and eating in a commensality setting has a number of positive effects on humans. The purpose of this paper is to investigate the effects of technology on commensality by presenting an experiment in which a toy robot showing non-verbal social behaviours tries to influence a participants' food choice and food taste perception. We managed to conduct both a qualitative and quantitative study with 10 participants. Results show the favourable impression of the robot on participants. It also emerged that the robot may be able to influence the food choices using its non-verbal behaviors only. However, these results are not statistically significant, perhaps due to the small sample size. In the future, we plan to collect more data using the same experimental protocol, and to verify these preliminary results.Interactive Intelligenc
