A study with rats shows that exposure to juvenile stress affects the reactivity to novel stressful situations in adulthood and may increase the risk to develop certain psychopathologies. Animals maintained in low-stress environments in adulthood show less interest for new situations, whereas if they are exposed to an intense stress there is an increase in animal's anxiety.
Wetlands are environments of high biodiversity, environmental value and water importance that play a relevant role in the ecosystem. The vegetation in these environments consists of aquatic plants in whose roots microorganisms live. A study shows that the roots of certain species have a selecting effect on the communities of microorganisms.
Archaeologists from the UAB shed light on the rich historical and archaeological heritage of La Almoloya, a site located in Murcia and the cradle of the "El Argar" civilisation which lived in the south-eastern part of the Iberian Peninsula during the Bronze Age. A silver diadem discovered in the royal tomb is the only one from that era conserved in Spain.
A study has examined the charred and non charred wood recovered in six stratigraphic levels of an archaeological site in the Argentine Patagonia dating from the Holocene.
