Abstract Background High-altitude ecosystems are extreme environments that generate specific physiological, morphological, and behavioral adaptations in ectotherms. The shifts gut microbiota of the ectothermic hosts as an adaptation to environmental changes still largely unknown. We investigated food ingested bacterial, fungal, protistan communities feces lizard Sceloporus grammicus inhabiting altitudinal range using metabarcoding approaches. Results bacterial phyla Bacteroidetes Firmicutes...
Agricultural practices affect the bacterial community structure, but how they determine response of to drought, is still largely unknown. Conventional cultivated soil, i.e. inorganic fertilization, tillage, crop residue removal and maize (Zea mays L.) monoculture, traditional organic farmed soil “milpa”, minimum rotation maize, pumpkin (Cucurbita sp.) beans (Phaseolus vulgaris fertilization were sampled. Both soils from central highlands Mexico characterized incubated aerobically at 5% field...
Microbialites are highly diverse microbial communities that represent modern examples of the oldest life forms, stromatolites (dated >3.7 Ga). Bacalar Lagoon, in Mexico, harbors largest freshwater microbialite occurrences world; yet anthropogenic activities changing oligotrophic conditions lagoon. The objective this work was to perform a spatial exploration microbialites analyze their prokaryote diversity, following high throughput sequencing approach V4 region 16S rDNA, and correlate...
Mangroves are unique coastal ecosystems, which have many important ecological functions, as they a reservoir of marine species well adapted to saline conditions and fundamental sites carbon storage. Although the microbial contribution nutrient cycling in these ecosystems has been recognized, there is lack information regarding composition structure different types mangrove forests. In this study, we characterized community (Bacteria Archaea) sediments associated with five forests lagoon...
Abstract The bacterial community in soil is often affected by agricultural practices, but how they affect protists and fungi less documented. Soil from treatments that combined different N fertilizer application rates, tillage crop residue management was sampled a field trial started the International Maize Wheat Improvement Center (CIMMYT) at ‘Campo Experimental Norman E. Borlaug’ (CENEB) Yaqui Valley northwest of Mexico early 1990s, fungal protist determined. Tillage, burning, had no...
Abstract In this study, the effect of deforestation and cultivation maize ( Zea mays L.) on physicochemical characteristics bacterial community structure in soil were studied at national park Área de Protección Flora y Fauna Nevado Toluca Mexico. Soil was sampled from three forested areas park, deforested grazed by animals cultivated with maize. The characterized chemically biologically, whilst investigated through 454 pyrosequencing 16S rRNA gene. pH forest decreased 6·1 to 5·3...
Plant-associated microbes have specific beneficial functions and are considered key drivers for plant health. The bacterial community structure of healthy Anthurium andraeanum L. plants was studied by 16S rRNA gene pyrosequencing associated with different parts the rhizosphere. A limited number taxa, i.e., Sinorhizobium, Fimbriimonadales, Gammaproteobacteria HTCC2089 were enriched in A. Endophytes more diverse roots than shoots, whereas all shoot endophytes found roots. Streptomyces,...
In this study we analyzed the microbiota composition of fecal samples from lesser-long nosed bat Leptonycteris yerbabuenae in different reproductive stages (juveniles and adult bats both sexes as well pregnant lactating females). The V4 region 16s rRNA gene 33 individuals was using alpha beta diversity metrics. We found that (expressed Amplicon Sequence Variants) is higher females. juveniles non-reproductive adults dominated by Gammaproteobacteria Firmicutes. Reproductive females had a much...
Eutrophication is a global problem causing the reduction of water quality and loss ecosystem goods services. The lakes "Lagunas de Montebello" National Park (LMNP), Chiapas, Mexico, not only represent unique beautiful natural scenic sites in southern Mexico but are also national protected area RAMSAR site. Unfortunately, some these started showing eutrophication signs since 2003. Anthropogenic activities (e.g., land-use change from forested to agricultural urban development) leading trophic...
The amount of nanoparticles (NP), such as TiO 2 , has increased substantially in the environment. It is still largely unknown, however, how NP might interact with earthworms and organic material this affect bacterial community structure their functionality. Therefore, an arable soil was amended at 0, 150 or 300 mg kg −1 subjected to different treatments. Treatments were ten ( Eisenia fetida (Savigny, 1826)) fully developed clitellum average fresh mass 0.5 500 g dry soil, 1.75 tyndallized...
Microorganisms in aerobic granules formed sequencing batch reactors (SBR) remove contaminants, such as xenobiotics or dyes, from wastewater. The granules, however, are not stable over time, decreasing the removal of pollutant. A better understanding granule formation and dynamics microorganisms involved will help to optimize contaminants wastewater a SBR. Sequencing 16S rRNA gene internal transcribed spacer PCR amplicons revealed that during acclimation phase relative abundance Acinetobacter...
We investigated the presence and diversity of bacteria in embryos viviparous lizard Sceloporus grammicus their amniotic environment. compared this to that found maternal intestine, mouth, cloaca. detected bacterial DNA embryos, albeit with a lower species than tissues. Most were also mother, although not all them. Interestingly, we high similarity composition among from different mothers. These findings suggest there may be mechanism controlling transmission mother embryo. Our results...
Microbialites are sedimentary structures that represent modern models of the oldest life forms, stromatolites (<3.5 Ga), and relevant for evolutionary ecological studies. Cenote Azul is a deep (>90 m) karst sinkhole in Yucatan peninsula characterized by microbialites develop along its wall hydrogeochemistry defined saturation carbonate, sulfate calcium ions. In this study, high throughput sequence analysis 16S rRNA genes allowed characterization prokaryotic communities associated with depth...
Halophiles can be found in hypersaline environments and they synthesize products of industrial interest. Method: In this work, 37 bacterial strains were isolated from the sediment a dried-out maar “Hoya Rincón de Parangueo” (Mexico) on different culture media with 20% NaCl pH 9, while potential extracellular enzymes determined. Results: Eight genera Salsuginibacillus, Alkalibacillus, Bacillus, Staphylococcus, Oceanobacillus, Halomonas Nesterenkonia besides 15 distinct species belonging to...
