Solutions to fire and shade: resprouting, growing tall and the origin of Eurasian temperate broadleaved forest.

Tree species of Eurasian broadleaved forest possess two divergent trait syndromes with contrasting patterns of resource allocation adapted to different selection environments: short-stature basal resprouters that divert resources to a bud bank adapted to frequent and severe disturbances such as fire and herbivory, and tall trees that delay reproduction by investing in rapid height growth to escape shading. Drawing on theory developed in savanna ecosystems, we propose a conceptual framework showing that the possession of contrasting trait syndromes is essential for the persistence of broadleaved trees in an open ecosystem that burns. Consistent with this hypothesis, trees of modern Eurasian broadleaved forest bear a suite of traits that are adaptive to surface and crown-fire regimes.

Small fire refugia in the grassy matrix and the persistence of Afrotemperate forest in the Drakensberg mountains.

Afrotemperate forests situated in the Drakensberg mountains of South Africa are characteristically small (1-10 s ha) and widely dispersed in a vast fire-prone grassland. Compared with lowland forests, they are typically species poor with low levels of endemism and species turnover, patterns that are to date unexplained. Here we show that the richness, composition and functional traits of tree species distributed on extremely small (10-100 s m) rocky fire-refugia situated in grassland are indistinguishable from that in forest.

Strengthening primary healthcare through community involvement in Cross River State, Nigeria: a descriptive study.

Introduction: In preparation for implementation of primary healthcare (PHC) services in Cross River State, a study to identify perceptions of communities and health systems concerning such interventions was conducted.

Methods: Existing PHC practices were documented through observation and document reviews, including facility checklists at frontline levels. Perceptions of consumers and providers on PHC were elucidated through 32 Focus Group Discussions (FGDs) and 78 semi-structured questionnaires.

Spatial distribution of urinary schistosomiasis in Cross River State, Nigeria using geographical information system and school based questionnaire.

Urinary schistosomiasis is a serious disease in Cross River State, Nigeria. Dearth of information on its distribution has hampered the implementation of focused control of the disease. The availability of a rapid method for mapping the disease necessitated this research to provide data for control of Urinary schistosomiasis in Cross River State, Nigeria.
