Dung beetles are holometabolous insects that feed on herbivorous mammal dung and provide services to the ecosystem including nutrient cycling soil fertilization. It has been suggested organisms developing incomplete diets such as dungs require association with microorganisms for synthesis utilization of nutrients. We describe diversity composition gut-microbiota during life cycle beetle Copris incertus using 16S rRNA gene sequencing. found C. gut contained a broad bacterial groups (1,699...

Cycads are among the few plants that have developed specialized roots to host nitrogen-fixing bacteria. We describe bacterial diversity of coralloid from seven Dioon species and their surrounding rhizosphere soil. Using 16S rRNA gene amplicon sequencing, we found all inhabited by a broad groups, including cyanobacteria Rhizobiales most abundant groups. The composition endophytes similar in six Mexican evaluated, suggesting recent divergence populations and/or plant-driven restrictions...

Abstract The karst underground river ecosystem of Yucatan peninsula is composed cave systems and sinkholes. microbial diversity water from this has been studied, but, structure the community in its sediments remained largely unknown. Here we describe how these changes due to different environmental conditions found sediment zones along caves a coastal an inland sinkhole. We that dominant groups varied according type sinkhole (Coastal: Chloroflexi Crenarchaeota; inland: Methylomirabilota...

Abstract Microbial communities from various environments have been studied in the quest for new natural products with a broad range of applications medicine and biotechnology. We employed an enrichment method genome mining tools to examine biosynthetic potential microbial sediments coastal sinkhole within karst ecosystem Yucatán Peninsula, Mexico. Our investigation led detection 203 gene clusters (BGCs) 55 secondary metabolites (SMs) 35 high‐quality metagenome‐assembled genomes (MAGs)...

Abstract The knowledge of the different population‐level processes operating within a species, and genetic variability individual prokaryotic genomes, is key to understanding adaptability microbial populations. Here, we characterized flexible genome ammonia‐oxidizing archaeal (AOA) populations using metagenomic recruitment approach long‐read (PacBio HiFi) sequencing. In lower photic zone western Mediterranean Sea (75 m deep), genomes Nitrosopelagicus brevis CN25 Nitrosopumilus catalinensis...

The Cortes geoduck ( Panopea globosa ) has been considered a Gulf of California (GC) endemic but anecdotal and unpublished evidence suggested its presence in Bahía Magdalena (BM), on the Pacific coast southern Baja California. Establishing identity clams their distribution limits is not only clear biological significance to understand structural functional variation, also consequence for conservation management, given multi-million dollar fishery they support north-west Mexico. We analysed...

Sharpnose sharks (genus Rhizoprionodon) experience extensive fishing pressure throughout their ranges in the Atlantic Ocean. As such, it is important to understand degree which intraspecific populations interact across a spatial gradient. The sharpnose shark (Rhizoprionodon terraenovae) and Caribbean porosus) share similar appearance presence within Gulf of Mexico, though until recently only R. terraenovae was observed north Bahamas. We assessed population structure using mitochondrial...

Coastal ecosystems are prone to hydrocarbon pollution due human activities, and this issue has a tremendous impact on the environment, socioeconomic consequences, represents hazard humans. Bioremediation relies ability of bacteria metabolize hydrocarbons with aim cleaning up polluted sites.The potential naturally occurring microbial communities as oil degraders was investigated in Sisal Progreso, two port locations southeast Gulf Mexico, both low level pollution. To do so, we determined...

Sponge-associated microorganisms are key influencers of nutrient biogeochemistry and important sources bioactive natural products. This study provides the first insights into taxonomic diversity microbial community associated with sponge Xestospongia sp. from an anchialine cave in coastal area underground river Yucatán Peninsula Xcalak, Quintana Roo, Mexico, potential antimicrobial activity its cultivable bacteria. High abundances Sulfurospirillum Desulfovibrio were detected 16S rRNA...

Abstract The anchialine ecosystem in the southeastern Gulf of Mexico has an unexplored fauna, among most understudied groups is Porifera, molecular approaches to investigate their biology and evolution remain largely short. To broaden these studies, sponge individuals collected cave “Xcalac” Mexican state Quintana-Roo were analyzed using 18S rRNA sequences from metagenomes. three studied belong Cinachyrella, Xestospongia, Suberites genera. mitochondrial (mt) genomes Cinachyrella sp. n....

Have you ever seen a picture of dinosaur and realized that there is palm-like plant by its side? Maybe have walked around your neighborhood the same kind there? Incredibly, those ancient plants, called cycads, been for millions years. A single cycad can live up to 2,000 years! We think secret cycads’ survival long life lies inside very special structure coralloid root, which has microbes living it. studied these roots found high diversity bacterial species them, more than anyone had...
