“…Another common substrate in the study area is the sandy bottom associated with seagrass meadows, where species of the family Udoteaceae, Caulerpaceae, Dichotomosiphonaceae and, Halimedaceae were located; these rhizophitic algae have a fixation system that allows them to live in unstable substrates and consolidate and prevent erosion of the sandy substrate. Rhizophitic algae are well-recognized as calcareous sediment producers, especially in tropical settings (Nelson 2009;Bedinger et al 2013).…”

In spite of it is baseline importance for comparative studies with the past and present data, an updated list of marine green algal taxa for the Biosphere Reserve of Sian Ka’an is not yet available. The aim of this paper is to present an updated list of marine green algal taxa for the Sian Ka’an Reserve based on literature and collections made by the authors in 17 localities during 2011–2012. Fifty-five taxa are new records for the study area and thus the list has increased to 129. Additionally five taxa are reported for the first time to Quintana Roo, and 11 to Mexican Atlantic coast. These results contribute to the knowledge of green seaweed diversity and also support the relevance of the Sian Ka’an Reserve as a high priority area for conservation due to their high level of algal biodiversity.

“…The correlation analysis also shows there is no statistically significant correlation between the cross-section area of the holdfast and the area of the thallus for Flabellophyton, r s (154) 0.091, p 0.262. In contrast, there is a positive correlation between the wet weight/ surface area of the above-sediment part and holdfast volume in modern algae (Anderson et al, 2006;Bedinger et al, 2013), possibly due to larger size, which experiences more dragging and have greater attachment strength (e.g., Denny et al, 1985;Wernberg and Thomsen, 2005).…”

Holdfast morphologies and attachment strategies of benthic macroalgae are somewhat flexible and controlled by both the substrate condition and species. Six forms (tapered base, globose holdfast, composite globose holdfast, discoidal holdfast, rhizoids and horizontal rhizomes) of attachment structures of Ediacaran benthic macroalgae are recognized from the early Ediacaran Lantian biota and late Ediacaran Miaohe biota in South China based on functional morphology. Each form is considered either adapted to firm substrates that dominate the Precambrian seafloor, or soft substrates that are more common in the Phanerozoic. The results show a diversification in both holdfast morphology and attachment strategies of macroalgae during the Ediacaran Period. In the early Ediacaran Lantian biota, none of the benthic macroalgae is adapted to soft substrates, while in the late Ediacaran Miaohe biota, a considerable number (41%) of species are adapted to relatively soft substrates. This shift might be an adaptive response to the diversification of macroalgae and a changing substrate condition during the Ediacaran Period: the decline of microbial mats and increase of water content in the sediments in the Ediacaran.

“…This ability to occupy several substrates is facilitated by its anchoring system formed by rhizoids that secrete mucilage that adheres to the background (Bedinger et al 2013). Udotea flabellum and U. dixonii were widely distributed along the Yucatan peninsula coast.…”

“…The blade is composed of dichotomously branched siphons (uncorticated blade) that, in some cases, bear simple to variously compound lateral appendages (corticated blade) ). The species of Udotea have an anchoring system composed of a net of rhizoids that binds sediments to form holdfast in unconsolidated sediments and function as early colonizers facilitating later establishment of the seagrasses (Zieman et al 1989, Williams 1990, Collado-Vides et al 1998, Bedinger et al 2013. Also, they are well-recognized as calcareous sediment producers because, even after death, the heavily calcified thalli of the Udoteaceae contribute to sand production, reef building, and provide organic matter that improves sediment nutrients when thalli decompose (Williams 1990, Hillis-Collinvaux 1997, Harney & Fletcher 2003, Van Tussenbroek & Van Dijk 2007.…”

Diversity and distribution of Udotea genus J.V. Lamouroux (Chlorophyta, Udoteaceae) in the Yucatan peninsula littoral, Mexico

A survey of the diversity, distribution, and taxonomy of the genus Udotea from the Yucatan peninsula littoral, Mexico, is presented. The results are based on a review of herbarium specimens, bibliographic data, and collections made by the authors during 2012-2016 at 34 localities along the study area. Macro and microscopic characteristics, relevant photographs, and descriptions are provided for each taxon. A total of 17 taxa of Udotea were recognized. One new record is cited for Quintana Roo, two for Yucatan, and five for Campeche coasts. The Quintana Roo littoral presents the highest number of Udotea species (17), followed by Campeche (13), and finally Yucatan (9). The Udotea taxa could be segregate by the presence of lateral appendages in the blade siphons and, the shape of the lateral appendages of the blade and stipe siphons.
