The aim of the program is to increase the level of surgical skilled health staff at district hospitals in Sierra Leone. CapaCare's goal is to train 30 medical doctors or community health officers within 2017.

Chronic stress modifies the structure and function of ecosystems through different processes. Despite that some convergent responses have been found, as changes in community composition and a reduction in diversity, there is unclear how this may affect to the processes explaining changes in beta diversity and ecosystem features. In my research, I used stream macroinvertebrates to explore these questions, as they offer interesting properties to test ecological hypotheses. As these organisms respond to marked environmental habitats, we use natural and anthropogenic stress gradients to see if the degree in which the regional pool of species is adapted to a type of stress, may cause patterns that help to predict responses to ongoing global change. In a first work, I found that natural and anthropogenic stressors reduced species richness and generate contrasting patterns in beta diversity that arise through different mechanisms. While species turnover along natural stress gradients, nested subset of species developed over anthropogenic stress gradients. In a second work, we estimate some functional diversity measures from a multidimensional space composed of axes that represented the variation in biological traits of the aquatic community. Functional measures consisted of mean taxon functional richness (functional variability at taxon level), functional similarity (the percentage of niche overlap between taxon pairs), functional richness (functional variability at community level), functional dispersion (mean departure from community centroid) and functional redundancy (sum of overlapping areas between species pairs). We found similar functional responses to natural and anthropogenic stress, where mean taxon niche and functional similarity augmented with increased stress, while functional richness, dispersion and redundancy decreased when stress intensity augmented. The reduction in functional richness arose from the development of nested subsets of community traits along stress gradient. The results of these studies may have strong conservation implications and may help to predict the ecosystem responses to global change and to elucidate how organisms colonized and evolved in stressful habitats.
