Early life disruption of the microbiota affects organ development and cytokine gene expression in threespine stickleback.

The microbiota that inhabits vertebrates exerts strong effects on host physiology and can be crucial to the development of a normal phenotype. This includes development of the immune system, somatic growth and maintenance, and morphogenesis. However, the genetic background of the host can also affect these life history traits.

Elimination communication contributes to a reduction in unexplained infant crying.

The Normal Crying Curve refers to infants' unexplained crying from birth to a peak at about 6-8 weeks, and self-resolving by three months. However, it is known that infants signal their need to eliminate (micturate/defecate) through a variety of cues, including fussing and crying. Elimination Communication (EC) refers to a caregiver's nurturant response to infant cues, while also using timing, to gently and non-coercively cradle the infant in a supported, secure squatting position to eliminate.
