Abstract Molecular studies were carried out on Chondrophycus gemmiferus and C. poiteaui (Rhodomelaceae) from the Mexican Caribbean Sea. These species are morphologically related, but differ mainly in presence of apiculate projection epidermal cells near apices branches. Both belong to Chondrophycus, as indicated by two periaxial per axial segment a 90° arrangement tetrasporangia, share characteristics with Laurencia (e.g., secondary pit connections between adjacent cells). The phylogenetic...
Pteronotus davyi, Davy's naked-backed bat, is a tropical bat whose current distribution in Mexico covers the watersheds of Pacific and Gulf coasts Mexico, converges at Isthmus Tehuantepec, continues into Yucatan peninsula. We evaluated phylogeographic relationships among 18 populations using data from nucleotide sequence hypervariable II domain mitochondrial DNA control region 105 specimens. Extant were distributed over 3 geographic regions (Pacific Coast, Southeastern) that delineated...
Caloglossa sp. 1, Bostrychia moritziana and radicans were collected from the mangroves of Barra de Navidad (Jalisco), San Blas (Nayarit) Teacapan (Sinaloa). 1 was previously known only Baja California Sur. calliptera obtained Estero Juan, (Nayarit). The concentrations D-mannitol, main osmolyte genus Caloglossa, ranged in C. 360 to 395 μmol/g DW when grown 25-35‰ seawater. In polyol contents correlated with salinity regime habitat

SUMMARY Prorocentrum micans Ehrenberg , gracile Schütt and sigmoides Böhm are planktonic dinoflagellates present along the Mexican Pacific coast. These three species can be treated as a complex because of similar shape size. The taxonomy group has been based on cell form size, presence or absence apical spines ornamentation main valves. A morphometric study samples from 11 locations coast laboratory cultures is presented. mucron (small tooth) in antapical region P. morphotypes was recorded...
:Molecular-assisted alpha taxonomy has provided novel ways of exploring biodiversity, and is great help in taxa where morphology alone not sufficient to ensure accurate species recognition or delimit boundaries. Here, we use this approach assess the Padina Adanson (Dictyotales, Phaeophyceae), a common brown algal genus Mexican waters. Numerous individuals from Pacific Atlantic tropical coasts were analysed using sequences psbA, cytochrome c oxidase subunit I, cox3 determine evolutionary...
Pyropia raulaguilarii sp. nov. is described from Michoacán, tropical Mexican Pacific, on basis of comparative morphology and nrSSU, rbcL sequence analysis. It distinguished other species by the foliose lanceolate gametophyte, a monoecious thallus zygotosporangia in packets 2x2x4. The phylogenetic analysis showed that two Pacific samples, Caletilla Carrizalillo (Michoacán), were almost identical formed distinctive well supported clade segregated Brazil, USA Mexico. entity morphologically...
Abstract The algae of El Salvador have received limited attention. We combined collections from the mangroves and neighboring southern Mexico, used culture studies molecular analysis to gain insights into diversity in this poorly explored region. Bostrychia montagnei , Caloglossa apomeiotica ogasawaraensis were newly recorded Salvador. has not been reported Pacific Americas before. B. normally produced axial cells with two-tier cells, typical species, but sometimes a series had three-tier...
Ulva fasciata Delile is reported for the first time as an introduced species along coast of Baja California Peninsula. In 2002–2003, populations U. were observed at only three sites (Monalisa Beach, El Faro Beach and mouth Punta Banda Estuary) on eastern side Todos Santos Bay, California, Mexico. The variation in mean thallus size suggests that this attains maximum development during late summer early autumn (September), gradually decreases autumn–winter disappears spring (April)....
The genus Rosenvingea is well known in the tropics. Four species have been reported from Pacific Mexico: R. floridana, antillarum, intricata and sanctae-crucis. We collected a plant (Boca del Cielo, Chiapas) that we identified as orientalis, not previously Mexico. were able to characterize life cycle of this for first time laboratory culture. It reproduced exclusively by plurilocular sporangia (plurangia). mature plants up 6 cm long with cylindrical compressed fronds (to 2 mm wide)...
A new species, Caloglossa apomeiotica West et Zuccarello, is described based on material from San Carlos, Bahia Magdalena, Bajo Califomia Sur. The species morphologically similar to C. leprieurii but characterised by the production of bisporangia and, less commonly, tetrasporangia, and lack sexually reproducing plants. In eight culture isolates throughout geographic range only were viable. present known distribution Baja California Sur Barra de Navidad, Jalisco in Pacific Mexico. It...
Se reportan los resultados de un estudio ficoflorístico realizado durante años 1980 y 1984 en la porción norte del estado Michoacán. presentan 68 especies distribuidas 43 géneros pertenecientes a las divisiones Cyanophyta, Chlorophyta, Phaeophyta Rhodophyta. reportan, también, nuevos registros para el Pacífico mexicano, así como Tropical mexicano exclusivamente. Asimismo, comentarios sobre hábitat, sustrato estadio reproductivo acompañan cada taxón reportado.

SUMMARY Ochtodes searlesii Mendoza‐González, Mateo‐Cid et Sentíes sp. nov. is described from Michoacán, tropical Mexican Pacific, on the basis of comparative morphology and rbc L sequence analysis. It distinguished other species by its erect axes arising an encrusting base, small terete fronds, regularly dichotomously branched axes, obliquely divided zonate tetrasporangia. Phylogenetic analyses showed that three Pacific samples, Caletilla, Zapote La Majahuita (Michoacán), were identical...
Abstract The brown alga Dictyota canariensis (Grunow) Tronholm has so far been reported only from the eastern Atlantic Ocean (Canary Islands, Cape Verde, Madeira). In present work, we record species for first time shores of Gulf Mexico, occurring in Montepío, Veracruz. specimens were collected December 2011 and October 2013, growing intertidal zone on moderately exposed rocky shores. To confirm identification, conducted phylogenetic analyses, combining partial sequences psb A cox 1 genes l7...

Acanthophoraspicifera, a red alga considered an alien species, was discovered for the first time on Pacific coast of Mexico in 2006 from locality inside La Paz Bay, Gulf California. Since then, more records have shown its presence, 17 localities having been added up to 2015. A two-year field study (2020-2022) visiting 31 sites along complemented with data literature and citizen science, resulted database 709 entries that spans 2004 2023. These showed distribution goes Punta Coyote, close...
SUMMARY Previous studies suggested that the biodiversity of mangrove‐associated Bostrychia radicans/Bostrychia moritziana species complex on Pacific coast Central America, based genetic and reproductive data, were low compared with similar areas Atlantic coast. Evolutionary scenarios proposed either a recent introduction to Pacific, or more uniform environment leading genetically connected populations differentiation between populations. We sampled extensively in southern Mexico, Guatemala...
