“…Unlike intracellular symbionts, which are strictly vertically transmitted to the embryo, gut associated microbes are mainly acquired during and after birth via horizontal transfer from the surrounding environment (Broderick and Lemaitre , Amato ). In many species, like the gypsy moth or the cabbage white butterfly, gut bacterial communities are highly dependent of food‐related bacteria and are mainly composed of widespread environmental taxa that opportunistically colonize the gut (Engel and Moran ).…”

The recent emergence of powerful genomic tools, such as high‐throughput genomics, transcriptomics and metabolomics, combined with the study of gnotobiotic animals, have revealed overwhelming impacts of gut microbiota on the host phenotype. In addition to provide their host with metabolic functions that are not encoded in its own genome, evidence is accumulating that gut symbionts affect host traits previously thought to be solely under host genetic control, such as development and behavior. Metagenomics and metatranscriptomics studies further revealed that gut microbial communities can rapidly respond to changes in host diet or environmental conditions through changes in their structural and functional profiles, thus representing an important source of metabolic flexibility and phenotypic plasticity for the host. Hence, gut microbes appear to be an important factor affecting host ecology and evolution which is, however, not accounted for in life‐history theory, or in classic population genetics, ecological and eco‐evolutionary models. In this forum, we shed new light on life history and eco‐evolutionary dynamics by viewing these processes through the lens of host– microbiota interactions. We follow a three‐level approach. First, current knowledge on the role of gut microbiota in host physiology and behavior points out that gut symbionts can be a crucial medium of life‐history strategies. Second, the particularity of the microbiota is based on its multilayered structure, composed of both a core microbiota, under host genetic and immune control, and a flexible pool of microbes modulated by the environment, which differ in constraints on their maintenance and in their contribution to host adaptation. Finally, gut symbionts can drive the ecological and evolutionary dynamics of their host through effects on individual, population, community and ecosystem levels. In conclusion, we highlight some future perspectives for integrative studies to test hypotheses on life history and eco‐evolutionary dynamics in light of the gut microbiota.

“…Modern high-throughput sequencing and bioinformatics tools provide a powerful means of understanding how the human microbiome contributes to health and its potential as a target for therapeutic interventions (21). Research is under way to establish normal host-gut microbe interactions and understand how microbiota compositional changes can cause certain diseases (22–24). …”

The human microbiota correlates closely with the health status of its host. This article analyzes the microbial composition of several subjects under different conditions over time spans that ranged from days to months. Using the Langevin equation as the basis of our mathematical framework to evaluate microbial temporal stability, we proved that stable microbiotas can be distinguished from unstable microbiotas. This initial step will help us to determine how temporal microbiota stability is related to a subject’s health status and to develop a more comprehensive framework that will provide greater insight into this complex system.

“…Investigations of primate behavioral ecology, physiology, and reproduction are relevant for life-history insights and biomedical translation (e.g. Amato, 2016; Kinnally, 2014; Hopper et al, 2008), by identifying reproductive mechanisms which are, otherwise, particularly difficult to isolate from socioeconomic and cultural factors in human studies (Phillips et al, 2014; Strier, 1994; Emery Thompson, 2013). Rhesus macaques live in multi-male, multi-female social groups and are typical Old World cercopithecines characterized by male dispersal, female philopatry, and matrilineal dominance hierarchies (Beisner and Isbell, 2011; de Waal and Luttrell, 1985).…”

Objectives The age at which females initiate their reproductive career is a critical life-history parameter with potential consequences on their residual reproductive value and lifetime fitness. The age at reproductive debut may be intimately tied to the somatic capacity of the mother to rear her young, but relatively little is known about the influence of age of first birth on milk synthesis within a broader framework of reproductive scheduling, infant outcomes, and other life-history tradeoffs. Material and Methods Our study investigated the predictors of age at first reproduction among 108 captive rhesus macaque (Macaca mulatta) females, and associations with their milk synthesis at peak lactation, infant mass and ability to subsequently conceive and reproduce. Results The majority of females reproduced in their fourth year (typical breeders); far fewer initiated their reproductive career one year earlier or one year later (respectively early and late breeders). Early breeders (3-year-old) benefited from highly favorable early life development (better juvenile growth, high dominance rank) to accelerate reproduction, but were impaired in milk synthesis due to lower somatic resources and their own continued growth. Comparatively, late breeders suffered from poor developmental conditions, only partially compensated by their delayed reproduction, and evinced compromised milk synthesis. Typical breeders not only produced higher available milk energy but also had best reproductive performance during the breeding and birth seasons following primiparity. Discussion Here we refine and extend our understanding of how life-history tradeoffs manifest in the magnitude, sources, and consequences of variation in age of reproductive debut. These findings provide insight into primate reproductive flexibility in light of constraints and opportunities.
