We describe a gradient of potential HIV transmission from HIV-infected persons to their partners and thence to uninfected populations. The effect of this newly discovered transmission gradient is to ...

Savannas intermingled with gallery forests are dynamic habitats typical in Africa. This study aims to determine if differences in species traits lead to non-overlapping distribution of gallery-forest ...

The decrease in liana diversity with increasing latitude has been indicated as the major physiognomic difference between tropical and temperate forests’ ecosystem. Despite the robustness of this ...

One of the most critical studies on microbial ecology is to reveal microbial turnover patterns along spatial, temporal, or environmental gradients. In such studies, it is often necessary to select ...
