Approximately 4,210 feet of Late Cretaceous and 1,440 feet of Tertiary sedimentary rocks are exposed in the Salt Wells Anticline area of southcentral Sweetwater County, Wyoming. Late Cretaceous units include the Blair, Rock Springs, Ericson, and Almond Formations of the Mesaverde Group and the Lewis Shale; Tertiary units include the...

Natural gas extraction, often referred to as “fracking,” has increased rapidly in the U.S. in recent years. To address potential health impacts, passive air samplers were deployed in a rural community heavily affected by the natural gas boom. Samplers were analyzed for 62 polycyclic aromatic hydrocarbons (PAHs). Results were grouped...

Wood is a major pool of organic carbon that is highly resistant to decay, owing largely to the presence of lignin. The only organisms capable of substantial lignin decay are white rot fungi in the Agaricomycetes, which also contains non–lignin-degrading brown rot and ectomycorrhizal species. Comparative analyses of 31 fungal...

Rapamycin (Rapa) and dietary restriction (DR) have consistently
been shown to increase lifespan. To investigate whether Rapa
and DR affect similar pathways in mice, we compared the effects
of feeding mice ad libitum (AL), Rapa, DR, or a combination of
Rapa and DR (Rapa + DR) on the transcriptome and...

We provide the first evidence on the causal effect of border enforcement on the
full spatial distribution of Mexican immigrants to the United States. We address the
endogeneity of border enforcement with an instrumental variables strategy based on
administrative delays in budgetary allocations for border security. We find that 1,000...

Large carnivores face serious threats and are experiencing massive declines in their populations
and geographic ranges around the world. We highlight how these threats have affected the
conservation status and ecological functioning of the 31 largest mammalian carnivores on
Earth. Consistent with theory, empirical studies increasingly show that large carnivores...

Anthropogenic and natural stressors often interact to affect organisms. Amphibian populations are undergoing unprecedented declines and extinctions with pesticides and emerging infectious diseases implicated as causal factors. Although these factors often co-occur, their effects on amphibians are usually examined in isolation. We hypothesized that exposure of larval and metamorphic amphibians...

Many Hymenoptera, with their painful stings and noxious chemical defenses,
exhibit bright aposematic warning color patterns and are the most frequently
mimicked group of organisms. Such aposematic color patterns are found in parasitic
wasps of the Neotropical Compsobracon group (Braconidae). Many members of this
group exhibit color patterns similar to...

A technique was developed in the present study to determine
fault-plane solutions for small earthquakes. The method uses the
direction and amplitude of initial P-wave motions recorded at a
small number of seismic stations for epicentral distances less than
2000 km.
Seismic arrivals recorded on short-period seismograms were

The Mount Fubilan Intrusion is part of a geologically young hypabyssal stock in the Star Mountains of Papua New Guinea. This stock was mapped as the Ok Tedi Intrusive Complex and divided into four separate bodies: the Mount Fubilan, Sydney Intrusion, Kalgoorlie, and Ningi Intrusions. Hydrothermal fluids caused alteration of...
