Periphyton communities of a boreal stream were exposed to different light and nutrient levels to estimate energy transfer efficiency from primary to secondary producers using labeling with inorganic (13)C. In a one-day field experiment, periphyton grown in fast-flow conditions and dominated by opportunistic green algae were exposed to light levels corresponding to sub-saturating (forest shade) ...

Synchrony is defined as to represent or arrange to indicate coexistence or parallel occurrence. Thus nutrient synchrony would imply a parallel occurrence of nutrients for the ruminant animal to consume or be present in the diet and rumen. Thus by supplying energy and nitrogen sources concurrently, an increase or optimization of microbial efficiency should occur. The increase in microbial effici...

The increasing demand for qualitative and varietal foods by the consumer society is a big concern energy production, utilization of that in judicious manner sustainable management resources challenge eminent future. Existing (land, water, fertilizer, etc.) their socioeconomic aspects warrant farming community to adopt alternative strategies aimed at enhancing use efficiency inputs improve envir...

Recent studies have provided evidence that trade-offs in biomass allocation, resource-use efficiency, and anti-herbivore defense influence seedling performance and distribution across soil types. Our previous research suggested that soil nutrient availability acted as a filter for understory palm community assembly and species coexistence in a lower montane forest in western Panama. Here, we ex...

Of the several mechanisms that can bring about efficient resource use, the most widelyapplicable one is intercropping systems that can make better use of resources. The aim of thisstudy was to evaluate resource capture and resource use efficiency in transgenic cotton-peanutintercropping system and in their respective sole crops with using 25-50% substitution ofrecommended dose of nitrogen (RDN)...

Adequate delivery of AA is essential for normal fetal growth and development. Recently, we reported that when ewes from the University of Wyoming flock (farm flock with adequate nutrition) were fed 50% (nutrient-restricted) or 100% (control-fed) of the NRC-recommended nutrient requirements between d 28 and 78 of gestation, fetal weights as well as concentrations of most AA in maternal and fetal...
