In Portugal, Mesolithic shellfisher/gatherers persisted in estuary environments, long after agricultural economies were established elsewhere. The co-existence of foragers and farmers makes Portugal an interesting region in which to study whether resource depression is a common factor in the adoption of agriculture. It is difficult to generalize about Mesolithic and Neolithic resource use, since faunal remains at archaeological sites reflect the variation in terrestrial and marine species available to inhabitants of rocky shores, sandy estuary environments, and interior zones. On the Costa Vicentina, where the transition to agriculture occurred quite early, assemblages from a variety of Mesolithic and Neolithic sites show a trend toward lower energetic returns from wild resources, both in shifting species compositions, and in shellfish diminution. The most significant decrease in foraging efficiency occurred across the Mesolithic/Neolithic transition, suggesting a causal relationship between resource stress and the emergence of farming.

Mais um ano...
"O Núcleo de Arqueologia e Paleoecologia surge da determinação de um grupo de alunos da Universidade do Algarve em dinamizar e promover a disciplina arqueológica. O Núcleo reuniu-se pela primeira vez no dia 8 de Novembro de 2008."
Assim se lê no preâmbulo do nosso regulamento...
O NAP - Núcleo de Arqueologia e Paleoecologia da Universidade do Algarve faz hoje 3 anos.
A todos os que contribuíram, contribuem e contribuirão para o crescimento e enriquecimento deste nosso projecto, o nosso muito obrigada.

IGC Cologne 2012 - DOWN TO EARTH
The 32nd International Geographical Congress in Cologne focuses scientific attention on the core themes of humanity. Researchers from around the world are expected in Cologne in 2012.
Geographers bring the wide-ranging perspectives and methodology of their subject to bear on four major thematic complexes and contribute to the solution of urgent scientific and socio-political issues – bringing research down to earth:
- Global Change and Globalisation
- Society and Environment
- Risks and Conflicts
- Urbanisation and Demographic Change

The effects of climate change on biodiversity should depend in part on climate displacement rate (climate-change velocity) and its interaction with species’ capacity to migrate. We estimated Late Quaternary glacial-interglacial climate-change velocity by integrating macroclimatic shifts since the Last Glacial Maximum with topoclimatic gradients. Globally, areas with high velocities were associated with marked absences of small-ranged amphibians, mammals, and birds. The association between endemism and velocity was weakest in the highly vagile birds and strongest in the weakly dispersing amphibians, linking dispersal ability to extinction risk due to climate change. High velocity was also associated with low endemism at regional scales, especially in wet and aseasonal regions. Overall, we show that low-velocity areas are essential refuges for Earth’s many small-ranged species.
