Through the analyses of stable isotopes of δ13C and δ15N in bone collagen, we aim to characterise the grazing systems and the maintenance strategies of the livestock that were consumed and raised in Leceia, in an attempt to obtain a further perspective on the economic complexity of the fortified settlements that emerged during the 3rd millennium in Portuguese Extremadura. The results show the possible use of forage to feed the animals and also seem to indicate the use of fertilised fields. This demonstrates that animal production is already based on intentional practices of animal and land management, as well as on complex exchange networks.

Para acrescentar valor, estes países terão que adicionar tecnologia aos seus produtos. São apresentados três casos de como as técnicas de microscopia e microanálise permitem antecipar e compreender o comportamento das rochas, em diversas condições climatéricas. Estas metodologias podem ser usadas em rocha de obra nova, eventualmente seguindo as normas vigentes ou em objetos património.
