Understanding connectivity among exploited populations is critical to their sustainable management and long-term viability. In the marine environment, estimates of connectivity often rely on the use of genetic markers, as dispersal primarily occurs during a planktonic larval phase which is difficult to track using direct methods. In this thesis, we...
Rainfall scarcity and variability present serious challenges to water security for many rural communities throughout the world's drylands. Sand dams--weirs built across ephemeral or seasonal rivers--provide an appropriate water harvesting and storage option for many regions. The structures quickly fill with sediment during rainy season flow events and store water...
The Miridae, or plant bugs, associated with noble fir, Abies
procera Rehd., are discussed. Thirty six species of the Miridae were
collected from noble fir. Twenty five of these species are considered
only "visitors" to noble fir. The study does not deal with these
species. Noble fir is a host...
