Maternal stress during pregnancy may shorten lifespans of male lizard offspring
Mother fence lizards that experience stress during pregnancy give birth to male offspring with shortened telomeres, or bits of non-coding DNA that cap the ends of chromosomes, according to a Penn State-led study. Shorter telomeres are associated with.....»»
Stressed rattlesnakes found to calm down in the company of a nearby "friend"
When a creature's stress levels decrease because of the presence of a companion, it is known as social buffering. In highly social animals, such as mammals and birds, this phenomenon is well studied. Now, researchers have examined social buffering in.....»»
