Article Synopsis
- Climate change is affecting mountain ecosystems by reducing winter snow cover, causing earlier spring snowmelt, and leading to shrub expansion in alpine areas.
- Research shows that changes in snow conditions impact soil microbial communities and function, with these effects lasting into summer.
- The expansion of ericaceous shrubs alters these impacts, enhancing certain soil microbes while reducing soil respiration and nitrogen availability, indicating that vegetation shifts can influence soil responses to climate change in alpine regions.
We assessed advertisements for children's toothpaste in two widely read US parenting magazines. Data on the number and type of toothpaste advertisements in two parenting magazines were collected from 116 magazine issues between 2007 and 2011. The number of children's toothpaste advertisements per year and across magazines was computed.

We elicited this response in human infants aged 3-6 months by placing a 15 delta prism (base-out) before one eye while they viewed a diffuse patch of light. Accommodation was measured and ocular alignment was confirmed with a video photorefractor.

Systolic time intervals were also simultaneously recorded by using the thermistor pulse transducer. At rest, in both groups, a positive linear regression was found between %D and cycle length (RR) (%D = 19.
