“…Further sampling campaigns paired with in-depth taxonomic studies are greatly needed in order to catalogue and quantify biodiversity in Mexican marine ecosystems (Salazar-Vallejo et al 2007;Bastida-Zavala et al 2013). Data on tardigrades from Mexico's Pacific maritime territory are still nonexistent.…”

Deep-water sampling in the Perdido Fold Belt, Gulf of Mexico, Mexican Economic Exclusive Zone yielded five specimens of tardigrades belonging to the genus Coronarctus Renaud-Mornant, 1974. The specimens represent the first records of the genus for Mexico. Two two-clawed larvae and two four-clawed larvae of Coronarctus mexicus Romano, Gallo, D'Addabbo, Accogli, Baguley & Montagna, 2011 and a single four-clawed larval specimen of an undescribed Coronarctus species were identified. Taxonomic analysis of the specimens contributed to the knowledge of deep-sea and Mexican marine tardigrades, two data-poor areas of study.

“…Our records are from a region in the Tropical Pacific marine littoral that has been considered as a hotspot for marine littoral biodiversity (Bastida-Zavala et al 2013). Concerning marine benthic cyanoprokaryotes, specially from intertidal and supratidal zones, this region´s previous studies (González-Resendiz et al 2013 have also shown a high potential for the discovery of new taxa to science.…”

Phylogenetic position reevaluation of Kyrtuthrix and description of a new species K. huatulcensis from Mexico´s Pacific coast

et al. 2016

Benthic marine heterocytous cyanoprokaryotes of Mexico´s tropical coast are being recognized as an important and conspicuous component of the supralittoral and intertidal zones usually described as an extreme and low diversity biotope. Although Kyrtuthrix has been reported from different coasts worldwide, its complex morphology has led to differing taxonomic interpretations and positioning. Ten marine supra and intertidal populations of Kyrtuthrix were analyzed using a detailed morphological approach, complemented with ecological and geographical information as well as DNA sequence data of the 16S rRNA gene and associated 16S-23S ITS. Kyrtuthrix huatulcensis is described as a new species, different from K. dalmatica Ercegovic and K. maculans (Gomont) Umezaki based primarily on morphological data. Our material has smaller dimensions in thalli, filaments, trichomes and cells, and possesses differences in qualitative characters as well. Our material is epilithic as in K. maculans but not endolithic as in K. dalmatica. The analysis of molecular data, mainly 16S rRNA gene sequence, show that this genus is within the Rivulariaceae clade, and outside of the Scytonemataceae clade. ITS secondary structure comparison with some of the closer representatives of Rivulariaceae shows considerable differences with these related genera. Based on the evidence gathered in this study, inclusion of Kyrtuthrix within the Rivulariaceae, rather than the Scytonemataceae, is fully supported.

“…Scutellastra mexicana, a species reaching maximum lengths of more than 35 cm (Dance, 1967;Powell, 1973) was even considered to be extinct (Simison, 1985;Gonçalves Borges, 2013), as a consequence of its overexploitation as a food source and adornments (Feinman and Nicholas, 2000), since pre-Columbian times (Melgar-Tísoc, 2007). However, recent studies have described the presence of some populations along the coast of mainland Mexico (Esqueda et al, 2000;Riosmena-Rodríguez et al, 2005;Ríos-Jara et al, 2006;Bastida-Zavala et al, 2013).…”

ABSTRACT1. Patella ferruginea is an endemic and endangered limpet of the Mediterranean Sea. Its distributional range has been greatly reduced over the past century, mainly as a consequence of human pressure on coastal habitats, and its presence is now confined to a few sites in the western Mediterranean basin.2. It was assumed that the island of Mal di Ventre was the only location hosting P. ferruginea in the central-western area of Sardinia (Italy), but reports from local people and the discovery of empty shells in surrounding areas suggested its distribution range may be greater than previously thought.3. Several systematic surveys for the presence of P. ferruginea were conducted during the summers of 2013 and 2014 at different locations of central-western Sardinia to improve knowledge about its conservation status and to verify various reported occurrences.4. Findings from this study confirm the critical status of conservation of the species in central-western Sardinia. The island of Mal di Ventre was confirmed as the main location hosting P. ferruginea and only one new small nucleus of limpets was found in a hardly accessible site on the coastline of the Sinis Peninsula (Cape San Marco). This nucleus represents the new southern distribution limit of the species in Sardinia.5. This work highlights the importance of awareness-raising activities and local environmental knowledge ('citizen science') as a source of information that can result in a better understanding of the distribution of this endangered species. Hardly accessible sites represent ideal locations to put in place conservation measures for the local P. ferruginea population but further studies, specifically aimed at determining the larval dispersal and connectivity among different limpet nuclei, are required.
