Assessing the fragility of forest remnants by using landscape metrics. Comparison between river basins in Brazil and Portugal.

The environmental vulnerability of a landscape is directly associated with any physical, geomorphological, and spatial factors which directly interfere with the ecological functionality of natural areas. Therefore, the composition, diversity, and structure of fragmented forest areas are essential to identify the patterns in the landscape and propose the most appropriate management measures for its conservation. The present study set out to analyse the applicability of landscape metrics for assessing the environmental fragility of forest remnants of different geographical conditions and phyto-physiognomies.

Spatial index relating urban environment to health lifestyle and obesity risk in men and women from different age groups.

The challenge in the search for relationships between urban space, physical mobility, and health status, is detecting indicators able to link the environment with healthy life habits. Therefore, the objective was to design an urban index for the identification of urban environment propensity for physical activity (PA) and to determine how it relates to lifestyle and anthropometric parametrization of obesity. Participants (N = 318-60.
