How do gap aspect, openness, age and gap density in the surroundings affect diversity and composition of lianas within treefall gaps? Are the variation patterns in liana communities within treefall gaps associated with ...

For decades, there has been debate about the possibility that organic farming can feed the world’s population. The most recent studies, analyzing the yields of individual crops, show a yield gap between organic and ...

infoplazas arose in Panama as means to combat the digital gap by providing Internet connectivity to the economically disadvantaged and geographically remote. Yet there is a dearth of information regarding their actual ...
