Abundance and diversity of microfungi in three coastal beaches of Mexico

Abstract

The abundance and diversity of species of microfungi was investigated on the beaches of Delfines, Km 24 Veracruz-Alvarado Highway, and El Coco, located on the coasts of the Caribbean Sea, Gulf of Mexico, and the Pacific Ocean, respectively. On each beach a sample composed of sand, subtidal wood or washed-up detritus with moist sand was collected. The samples were analyzed by three different methods, resulting in a total of 1,160 occurrences that fluctuated between 340 and 441 occurrences/sample. The number of species/sample fluctuated between 20 and 32. A total of 52 species was found, of which 12 were marine, and 40 nonmarine, of terrestrial origin, and of these 15 were ascomycetes, 34 were hyphomycetes, 2 were blastomycetes and one was a coelomycete. The abundance distribution showed few species with high or low values, with the greatest proportion having intermediate values. In order to compare species diversity among the samples frequency curves were utilized, based on the number of species expected from samples taken at random; the results showed that the beach at El Coco was richest in species.

Culturable halotolerant fungal isolates from Southern California Gulf sediments

“…Some of the micromycetes found in this work had already been reported in Mexico, such as: Aspergillus spp (sand beach) (Gonzalez et al 1998; sediments; Scopulariopsis spp (Alias and Jones 2000) from mangroves (Kohlmeyer 1968), and plant material (Jones et al 2009;Singh et al 2012) and Peniophora spp from marine sponges (Bonugli-Santos et al 2016). Phialosimplex sclerotialis and P. caninus have recently been reported in deep marine sediments (Singh et al …”

“…In Mexico there have been a few studies of marine fungi, including fungal isolates from beach sand, sea foam, floating wood and mangrove (Gonzalez et al 1998;Gonzalez et al 2000;Gonzalez et al 2001); however, none has been reported from marine sediments under 40 m deep as we did. The aim of this study was to isolate and identify marine halotolerant fungi from sediments of the Southern California Gulf.…”

“…, Cladosporium spp (sand beach) (Gonzalez et al 1998), Phoma spp (sand beach) (Gonzalez et al 1998), and mangrove (Kohlmeyer 1968), Scopulariopsis spp (sand beach) (Gonzalez et al 1998;Gonzalez et al 2000), and sea foam (Kohlmeyer 1968), and Chaetomium spp (sand beach) (Gonzalez et al 1998). However, there had been no reports on deep marine sediments from Mexico.…”

Microfungal community associated with rhizosphere soil of Zygophyllum qatarense in arid habitats of Bahrain

“…To quantify microbial abundance and diversity in the rhizosphere soil of Z. qatarense in saline and nonsaline habitats, data were analysed according to statistical methods as outlined by Mandeel et al (1995) and Gonzalez et al (1998). The abundance of species (n) is expressed as the number of individual occurrences of a species.…”

A High-Level Fungal Diversity in the Intertidal Sediment of Chinese Seas Presents the Spatial Variation of Community Composition

“…Next-generation sequencing-based studies are rare, except Arfi et al (2012) who investigated the anoxic mangrove sediments of Saint Vincent Bay, and revealed that Agaricomycetes was the dominant fungal class. As a result, insufficient information on the fungal community in the sediment of intertidal ecosystems is hindering our understanding of their ecological functions (González et al, 1998; Sallenave-Namont et al, 2000; Rämä et al, 2014). …”
