The knowledge, and proper and correct mention of the names assigned to taxa in a floristic study is perhaps the most important task at the beginning of any taxonomic work or in the analysis of a specific group. First, because it makes clear to readers, specialized or not, which circumscriptions they are using and the identities of their work units;...

This contribution is part of a series that aims to disseminate good taxonomic practices among phycologists. In this paper, we address the use of the correct name, instead of the widespread practice of using a valid name to cite taxonomically accepted names. Some related concepts, present in the Code, are mentioned, such as: the legitimate name, val...

The estimation of biodiversity has become, in these times, a pressing and fundamental task for the knowledge and conservation of the species that are in a given geographical space. This, based mainly on the very high rate of extinction of diverse organisms and the accelerated modification of different natural scenarios by humans. Even this task has...
Article
In this work five biorefinery scenarios are proposed for the production of five different target products. Two of these scenarios included biodiesel production from Scenedesmus dimorphus microalgae biomass and glycerol valorization through bioconversion into dihydroxyacetone (DHA) with the bacteria Gluconobacter oxydans. Experimental data of microa...

In the last 20 years, the use of two abbreviations that were not common in the phycological literature has increased: aff. and cf. or cfr. These are as an alternative to the identification given the impossibility of assigning a specific or generic epithet to some individuals or representatives of a specific floristic study. The use of these abbrevi...

The rules for quoting the author of a scientific name are covered by the Code of Nomenclature of Algae, Mushrooms and Plants, in chapter VI, section 1, of Articles 46 to 50. However, one of the problematic cases, at least in the biological nomenclature is the use of the authors' initials in scientific names. C. Agardh, J. Agardh, W. West, G. S. Wes...

A unicellular cyanobacterium, strain Alchichica-D10, was isolated from microbialites of the alkaline Lake Alchichica, Mexico. The cells were short rods (3.9 ± 0.6 μm in length and 1.1 ± 0.1 μm in width) forming biofilms of intense emerald green color. They exhibited red autofluorescence under UV light excitation. UV-visible absorption spectra revea...

We provide the first record of Anorthoneis dulcis Hein in México in two Oases of the southern Baja California Peninsula, thus extending the geographic distribution of this species in North America from East (Florida) to West (Baja California Sur). The pH values observed at one of the Oases (7.1-8.9) show that A. dulcis may thrive in a wider range o...

Algae on Mayan monuments are part of the biodiversity of the tropical zone and are not responsible for their deterioration, and can even help preserve them by reducing the impact of weathering. It is necessary to maintain them, and in some cases, for esthetic reasons, control their growth. Knowing the physiological and ecological responses of algae...
