Baboons inform on human gut microbiota Commensal bacteria are found throughout an organism, but it is not known whether associations between and their host heritable. Grieneisen et al. examined changes in the microbiomes of 585 wild baboons from fecal samples collected over 14 years (see Perspective by Cortes-Ortiz Amato). Almost all microbiome traits tested demonstrated some level statistically significant heritability. Most heritability values were low varied time correlating with age...
Humans are inextricably linked to each other and our natural world, microorganisms lie at the nexus of those interactions. Microorganisms form genetically flexible, taxonomically diverse, biochemically rich communities, i.e., microbiomes that integral health development macroorganisms, societies, ecosystems.
Across group-living animals, linear dominance hierarchies lead to disparities in access resources, health outcomes and reproductive performance. Studies of how rank predicts these traits typically employ one several metrics without examining the assumptions each metric makes about its underlying competitive processes. Here, we compare ability two metrics-simple ordinal proportional or 'standardized' rank-to predict 20 a wild baboon population Amboseli, Kenya. We propose that simple best when...
Ecological relationships between bacteria mediate the services that gut microbiomes provide to their hosts. Knowing overall direction and strength of these is essential learn how ecology scales up affect microbiome assembly, dynamics, host health. However, whether bacterial are generalizable across hosts or personalized individual debated. Here, we apply a robust, multinomial logistic-normal modeling framework extensive time series data (5534 samples from 56 baboon over 13 years) infer...
Mammalian gut microbiomes are highly dynamic communities that shape and shaped by host aging, including age-related changes to immunity, metabolism, behavior. As such, microbial composition may provide valuable information on biological age. Here we test this idea creating a microbiome-based age predictor using 13,563 profiles from 479 wild baboons collected over 14 years. The resulting “microbiome clock” predicts chronological Deviations the clock’s predictions linked some demographic...
ABSTRACT Leptospirillum spp. are widespread members of acidophilic microbial communities that catalyze ferrous iron oxidation, thereby increasing sulfide mineral dissolution rates. These bacteria play important roles in environmental acidification and harnessed for bioleaching-based metal recovery. Known the clade Nitrospira phylum ferrooxidans (group I), ferriphilum “ rubarum ” II), ferrodiazotrophum III). In Richmond Mine acid mine drainage (AMD) system, biofilm formation is initiated by...
Understanding why some individuals age faster than others is essential to evolutionary biology and geroscience, but measuring variation in biological difficult. One solution may lie gut microbiome composition because microbiota change with many age-related factors (e.g., immunity behavior). Here we create a microbiome-based predictor using 13,563 microbial profiles from 479 wild baboons collected over 14 years. The resulting “microbiome clock” predicts host chronological age. Deviations the...
March Mammal Madness is a science outreach project that, over the course of several weeks in March, reaches hundreds thousands people United States every year. We combine four approaches to – gamification, social media platforms, community event(s), and creative products run simulated tournament which 64 animals compete become champion. While encounters between are hypothetical, outcomes rely on empirical evidence from scientific literature. Players select their favored combatants...

Studies of how rank affects these outcomes typically employ one several metrics without examining the assumptions each metric makes about its underlying competitive processes. Here we compare ability two metrics—ordinal proportional or ‘standardized’ rank—to predict 20 distinct traits a well-studied wild baboon population Amboseli, Kenya....

Abstract Human gut microbial dynamics are highly individualized, making it challenging to link microbiota health and design universal microbiome therapies. This individuality is typically attributed variation in host genetics, diets, environments, medications, but could also emerge from fundamental ecological forces that shape more generally. Here we leverage extensive time series wild baboons—hosts who experience little interindividual dietary environmental heterogeneity—to test whether...
Abstract Ecological relationships between bacteria mediate the services that gut microbiomes provide to their hosts. Knowing overall direction and strength of these within hosts, generalizability across is essential learn how microbial ecology scales up affect microbiome assembly, dynamics, host health. Here we gain insight into patterns by inferring thousands correlations in bacterial abundance pairs taxa from extensive time series data (5,534 profiles 56 wild baboon hosts over a 13-year...
Public engagement is increasingly viewed as an important pillar of scientific scholarship. For early career and established scholars, navigating the mosaic landscape public education science communication, noted for rapid "ecological" succession, can be daunting. Moreover, academics are characterized by diverse skills, motivations, values, positionalities, temperaments that may differentially incline individuals to particular translation activities.Here we briefly contextualize activities...
ABSTRACT Gene expression profiles provide insight into how microorganisms respond to changing environmental conditions. However, few studies have integrated profile analyses of both coding genes and non-coding RNAs (ncRNAs) characterize the functional activity microbial community members. Here, we defined gene from laboratory-grown acidophilic biofilms using RNASeq. In total, 15.8 million Illumina reads were mapped genomes 26 nine viruses reconstructed Richmond Mine at Iron Mountain,...
