New federal water quality regulations regarding impaired waters and urban stormwater, alongside a growing need to reverse eutrophication of urban lakes, are creating demand to decrease nutrient export from urban landscapes, particularly lawns. We propose that Nowak et al.’s (2006) disproportionality framework could be used to target specific households likely to generate disproportionate levels...

The Mediator complex was originally discovered in yeast, but it is conserved in all eukaryotes. Its best-known function is to regulate RNA polymerase II-dependent gene transcription. Although the mechanisms by which the Mediator complex regulates transcription are often complicated by the context-dependent regulation, this transcription cofactor complex plays a pivotal role in numerous biologic...

Indonesia has a huge potential of mangrove resources. In 2010, the mangrove area was 5,209,543.16 hectares and the area was decline rapidly to 2,496,185 hectares in 2016. This figure shows depletion and degradation of mangrove ecosystem and therefore, the capacities to supply human needs are decline because of the intense pressure from many activities in the development of coastal zone. The dat...

In a food web, nutrients flow via trophic links. For this reason, trophic interactions have a fundamental character due to the principle of mass conservation. To further comply with this principle, we consider a food web model that includes nutrient cycling. Non-trophic effects amongst species of the food web are modelled as interaction modifications, i.e., a functional change in the trophic in...

Ribosomal RNA gene (rDNA) copy number variation modulates heterochromatin formation and influences the expression of a large fraction of the Drosophila genome. This discovery, along with the link between rDNA, aging, and disease, high-lights the importance of understanding how natural rDNA copy number variation arises. Pursuing the relationship between rDNA expression and stability, we have dis...

There are currently few sensor systems capable of measuring soil parameters at multiple points in space over time consistently and economically, and without disrupting activities at the land surface. We have developed prototype nodes of a wireless sensor network for agricultural monitoring and management. The underground nodes are capable of transmitting soil measurements of moisture at schedul...

“why” mind-set. We are particularly interested in your thoughts about recycling. In particular, we are interested in your thoughts about why you would recycle. For example, what are the underlying reasons for recycling, for what purpose would you recycle, etc.? Please take some time below to explain why you would go about recycling.

The significance of volunteering for both individuals and society has lead to numerous studies on this behavior across the social sciences. However, virtually no prior research has evaluated how and to what extent organizations can effectively encourage individuals to contribute time to a worthy cause. The present research uses a social norm perspective to examine the conditions under which pro...

Wetlands seem to be especially vulnerable to invasions. Even though ≤6% of the earth’s land mass is wetland, 24% (8 of 33) of the world’s most invasive plants are wetland species. Furthermore, many wetland invaders form monotypes, which alter habitat structure, lower biodiversity (both number and “quality” of species), change nutrient cycling and productivity (often increasing it), and modify f...

The first eclipsing binary pulsar, PSR B1957+20, was discovered in 1987. Since then, 13 other eclipsing low-mass binary pulsars have been found; 12 of these are in globular clusters. In this paper we list the known eclipsing binary pulsars and their properties, with special attention to the eclipsing systems in 47 Tuc. We find that there are two fundamentally different groups of eclipsing binar...
