Development of conceptacles in Amphiroa (Corallinales, Rhodophyta)
Rosas-Alquicira, Edgar; Riosmena-Rodríguez, Rafael; Hernández-Carmona, Gustavo; Neto, Ana I.Here, we describe the development of sporangial and gametangial conceptacles for Amphiroa beauvoisii and A. vanbosseae; sporangial conceptacles only for A. misakiensis; and gametangial conceptacles only for A. cryptarthrodia and A. rigida. The descriptions are based on the observation of histological preparations obtained from 112 specimens collected from the Gulf of California, in Mexico, and the Azores archip...
A re-evaluation of Scinaia (Nemaliales, Rhodophyta) in the Azores.
Léon-Cisneros, Karla; Riosmena-Rodriguez, Rafael; Neto, Ana I.Copyright © Springer-Verlag and AWI 2011. ; The genus Scinaia in the Azores is re-evaluated based on historical and recent collections. A combination of morphological and anatomical diagnostic characters was used for species segregation, and a key for Azorean species determination is presented. Anatomical information associated to the hair development is described for the first time for the genus. The occurren...
Life-cycle of Scinaia interrupta (Nemaliales, Rhodophyta)
León-Cisneros, Karla; Nogueira, Eunice M.; Riosmena-Rodriguez, Rafael; Neto, Ana I.Copyright © Springer Science+Business Media B.V. 2011. ; The life-cycle of Scinaia interrupta (A.P. de Candolle) M. J. Wynne was investigated in vitro using four irradiance regimes: 4, 8, 12 and 16 μmol photons mˉ² sˉ¹. A triphasic heteromorphic life-cycle was observed. Carpospores released by cystocarps of gametophytes collected in the field developed into filamentous tetrasporophytes, which produced tetrahed...

Rosas-Alquicira, Edgar; Riosmena-Rodriguez, Rafael; Couto, Ruben P.; Neto, Ana I.Copyright (c) 2009 - Station Biologique de Roscoff - Abims. ; Non-geniculate coralline algae are abundant and ecologically important in the Azorean littoral, although they have been investigated only sporadically. This paper is the first report on the occurrence of Neogoniolithon brassica-florida, Lithophyllum crouanii and Phymatolithon calcareum as rhodoliths in the Azores (the first two in Ilhéu de Vila Fran...
