Intraspecific olfactory signals known as pheromones play important roles in insect mating systems. In the model Drosophila melanogaster, a key part of the pheromone-detecting system has remained enigmatic through many years of research in terms of both its behavioral significance and its activating ligands. Here we show that Or47b-and Or88a-expressing(More)
Keywords: Slug test Aquifer characterization Wellbore skin Identifiability Kozeny–Carman s u m m a r y A recently developed unified model for partially-penetrating slug tests in unconfined aquifers (Malama et al., in press) provides a semi-analytical solution for aquifer response at the wellbore in the presence of inertial effects and wellbore skin, and is(More)
A neutron probe device is a quick, reliable way to capture an instantaneous soil moisture profile. High spatial resolution neutron probe measurements can be recorded along a vertical profile and be used to look at seasonal changes in moisture content and vertical and lateral variations related to subsurface stratigraphy. In addition to seasonal changes,(More)

Flying insects are well known for airborne odour tracking and have evolved diverse chemoreceptors. While ionotropic receptors (IRs) are found across protostomes, insect odorant receptors (ORs) have only been identified in winged insects. We therefore hypothesized that the unique signal transduction of ORs offers an advantage for odour localization in(More)
Keywords: Noble gas thermometry Seasonal recharge Mountain block recharge Agricultural recharge Irrigation Infiltration temperature s u m m a r y Thirteen noble gas samples were collected from eleven wells and two mountain springs in the Treasure Valley, Idaho, USA to derive recharge temperatures using noble gas thermometry. One common assumption with noble(More)
Most naturally occurring olfactory signals do not consist of monomolecular odorants but, rather, are mixtures whose composition and concentration ratios vary. While there is ample evidence for the relevance of complex odor blends in ecological interactions and for interactions of chemicals in both peripheral and central neuronal processing, a fine-scale(More)
Between 2010 and 2011, six Advanced Tensiometer (AT) soil nests were installed at the Boise Hydrogeophysical Research Site (BHRS) to monitor soil pore water pressure and temperature in coarse conglomeratic sediments and to aid in estimation of unsaturated hydrologic properties of these materials. Four nests were installed in the spring of 2010 and two more(More)
In their natural environment, insects such as the vinegar fly Drosophila melanogaster are bombarded with a huge amount of chemically distinct odorants. To complicate matters even further, the odors detected by the insect nervous system usually are not single compounds but mixtures whose composition and concentration ratios vary. This leads to an almost(More)
