A rich and very dynamic Content distribution ecosystem enables today’s Internet users to access content associated with major providers from a close-by front-end server. While the advantages of the resulting locality of traffic for users (i.e. better performance) and providers (i.e. lower cost) are well understood, two basic questions about the content distribution ecosystem remained unanswered...

Freshwater flows have an important influence on the balance of fish species in estuaries. As well as supporting general ecosystem health, these flows are also necessary to comply with Australia-wide legislation aimed at the sustainable management of water resources. The Coastal Zone CRC and Fisheries Research and Development Corporation (FRDC) instigated the ‘environmental flows for estuaries’ ...

Individual perceptions are essential when evaluating the well-being benefits from urban green spaces. This study predicted the influence of perceived green space characteristics in the city of Szeged, Hungary, on two well-being variables: the green space visitors' level of satisfaction and the self-reported quality of life. The applied logistic regression analysis used nine predictors: seven pe...

Vermelha Lagoon is a hypersaline shallow transitional ecosystem in the state of Rio de Janeiro (Brazil). This lagoon is located in the protected area of Massambaba, between the cities of Araruama and Saquarema (Brazil), and displays two quite uncommon particularities: it exhibits carbonate sedimentation and displays the development of Holocene stromatolites. Due to both particularities, the sal...

Biodiversity conservation and human well-being are tightly interlinked. Yet, mismatches in the scale at which these two priority issues planned implemented have exacerbated biodiversity loss, erosion of ecosystem services declining quality life. India houses second largest population on planet, while < 5% country’s land area is effectively protected for conservation. This warrants landscape-lev...

Theory predicts, and recent empirical studies have shown, that the diversity of plant species determines the diversity of associated herbivores and mediates ecosystem processes, such as aboveground net primary productivity (ANPP). However, an often-overlooked component of plant diversity, namely population genotypic diversity, may also have wide-ranging effects on community structure and ecosys...

A conceptual architecture for ambient assisted living is introduced as a contribution to the development of an ecosystem of products and services supporting active ageing. In order to facilitate understanding and better interrelate concepts, a 3-layered model is adopted: Infrastructure layer, Care and assistance services layer, and AAL ecosystem layer. A holistic perspective of ambient assisted...
