The relentless roar of natural gas compressors influences the numbers of insects and spiders nearby, triggering decreases in many types of arthropods sensitive to sounds and vibrations, a collaborativ...
Study Shows Large Variability in Abundance of Viruses that Infect Ocean Microorganisms
Large Variability Viruses Infect Ocean Microorganisms
2016/2/22
Collecting and re-examining more than 5,600 estimates of ocean microbial cell and virus populations recorded over the past 25 years, researchers have found that viral populations vary dramatically fro...
Intermediate disturbance promotes invasive ant abundance
Linepithema humile Urban–rural gradient
2015/12/10
Urban habitats are undergoing a faunal and floral homogenization process worldwide. We investigated
how such homogenization influences ant communities. We monitored ant species richness a...
Elevated CO2 decreases the response of the ethylene signaling pathway in Medicago truncatula and increases the abundance of the pea aphid
Acyrthosiphon pisum (pea aphid) elevated CO2 ethylene Medicago truncatula nitrogen (N) metabolism resistance
2015/2/5
The performance of herbivorous insects is greatly affected by plant nutritional quality and resistance, which are likely to be altered by rising concentrations of atmospheric CO2.We previously repor...

2014/12/26
We present Submillimeter Wave Astronomy Satellite observations of water vapor in two cold starless clouds, B68 and core D in ρ Ophiuchi. Sensitive nondetections of the 110-101 transition of o-H2O are ...
Chandra Detection of Fe XVII in Absorption: Iron Abundance in the Hot Gaseous Interstellar Medium
4U 1820–303 abundances
2014/12/24
The iron depletion level and the gas-phase iron abundance in the hot (~106 K) interstellar medium (ISM) are critical to our understanding of its energy balance as well as the thermal sputtering, cooli...

Taxon- and vector-specific variation species richness abundance the transport stage of biological invasions
2014/4/2
Recent empirical and statistical evidence suggest that propagule pressure (i.e., number of individuals introduced per event, and the number and frequency of events) and colonization pressure (i.e., nu...
Large-scale geographical variation in prokaryotic abundance and production in meso- and bathypelagic zones of the central Pacific and Southern Ocean

Heterotrophic production and abundance of prokaryotes (i.e.,BacteriaandArchaea) in meso- (200–1000 m) and bathypelagic (.1000 m) zones were measured at 31 stations along meridional transects of the ce...
Feeding and overwintering of Antarctic krill across its major habitats: The role of sea ice cover, water depth, and phytoplankton abundance
Antarctic krill Feeding water depth
2014/4/2
Antarctic krill (Euphausia superba) were sampled in contrasting habitats: a seasonally ice-covered deep ocean
