Three Uncommon Seaweeds of the Pacific Coast of Mexico  [PDF]
A. Catalina Mendoza-González, Luz Elena Mateo-Cid, Deisy Yazmín García-López
American Journal of Plant Sciences (AJPS) , 2015, DOI: 10.4236/ajps.2015.619310
Abstract: This report describes a new record and two unusual and rare species of marine algae collected from Oaxaca, Michoacán, Jalisco and Baja California Sur at Mexican Pacific coast. Boodleopsis verticillata is the first record in the Pacific shore of Mexico, in the case of Melobesia polystromatica, this is the sixth record at tropical Pacific while Litholepis sonorensisis reported for the third time in the Gulf of California. These results suggest that the taxonomic inventory of seaweed in the Pacific coast of Mexico is not yet complete, so attention must be given to the epiphytes, and other small and delicate species that inhabit the coast of Mexico. Morphological descriptions, distributional range, reproductive stage and samples examined are included.

Luz Elena Mateo-Cid, A. Catalina Mendoza-González, Luis E. Aguilar-Rosas, Raúl Aguilar-Rosas
American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.412A2001
Abstract:

This paper provides a description of the articulated species of the Tribe Janieae (Corallinales, Rhodophyta) in the Pacific coast of Baja California and Gulf of California, Mexico. This taxonomic report is based on newly collected data in the study area and material currently housed at several herbaria. As a result of the present study, the record of the tribe Janieae is represented at the Pacific coast of Mexico for one genus: Jania J. V. Lamouroux with nine species. Morphological, reproductive and anatomical descriptions are provided in detail. In addition, keys for determination are included, as well as habitat, nomenclature, comparisons with other species and information on distribution. Instead of eleven species of Jania currently recorded for the study area, we recognize only nine. Jania verrucosa is restricted to the occidental coast from the Peninsula of Baja California. The remainder of the species commonly occurs in the Gulf of California and the Pacific coast of Baja California’s Peninsula. On the other hand, the gametangial thalli of J. adhaerens and tetrasporangial conceptacle in J. longiarthra are reported for the first time in Mexico.

Abstract: Se realizaron muestreos de Amphiroa beauvoisii (Corallinales, Rhodophyta) en diversas localidades de las costas del Pacífico y Caribe mexicano de 1994 a 2007 y se efectuó una extensa revisión bibliográfica de los trabajos en los que se cita Amphiroa beauvoisii. Asimismo, se revisaron los ejemplares depositados en herbarios nacionales y extranjeros, con el propósito de determinar la distribución latitudinal, y la variación morfológica y reproductiva de esta especie. El análisis de la información nos indica que se encuentra ampliamente distribuida en la costa del Pacífico desde islas Coronados, Baja California hasta La Ventosa, Oaxaca, siendo muy frecuente en el golfo de California y en los estados de Jalisco, Guerrero y Oaxaca, mientras que en la costa atlántica su distribución se encuentra restringida a los arrecifes coralinos de Yucatán y Quintana Roo. Se describen en forma detallada los caracteres morfo-anatómicos y reproductivos. En general se observó que los talos tetrasporangiales y bisporangiales son frecuentes, de mayor talla y más ramificados que las plantas gametangiales. El material examinado mostró que en la costa del Pacifico se encuentran los talos tetrasporangiales, bisporangiales y gametangiales, mientras que en la costa del Caribe mexicano sólo se presentan poblaciones tetrasporangiales. Se registra por primera vez la fase gametofitica masculina y femenina de A. beauvoisii en poblaciones mexicanas.
