The spatial distribution and patterns of habitat use of littoral fish species in Lake Constance were studied using electric fishing and trammel net sampling to assess fish abundance and biomass in three depth strata at six different sampling sites within the littoral zone. Distribution differences among depth strata were found to be often more pronounced than among different sampling sites. Juv...

Many clean energy technologies have experienced rapid cost declines recently as a result of accumulating experience with their production and use. It has been argued that if this relationship between experience and cost continues in the future, then it may make sense to foster market penetration of clean energy technologies on a large scale today, despite their current high costs, in order to d...

The Israel–Egypt border region composed of longitudinal sand dunes is a very unique arid environmental ecosystem in the world: the Israeli side with much more vegetation cover has notably higher land surface temperature (LST) during daytime than the Egyptian side where bare sand prevails. In order to understand this thermal anomaly and its scientific significance in the arid environmental ecosy...

Improving a decision maker’s1 situational awareness of the cyber domain isn’t greatly different than enabling situation awareness in more traditional domains2. Situation awareness necessitates working with processes capable of identifying domain specific activities as well as processes capable of identifying activities that cross domains. These processes depend on the context of the environment...

Background: Cost-effective approaches to improve feeding practices and to reduce undernutrition are needed in low-income countries. Strategies such as nutritional counseling, food supplements, and cash transfers can substantially reduce undernutrition among food-insecure populations. Lipid-based nutrient supplements (LNS) are an increasingly popular strategy for treating and preventing undernut...
