First Report Of Invasive Crane Fly, Tipula Oleracea, In Utah, A Van Dyke, Ricardo A. Ramirez, B A. Mcgraw
First Report Of Invasive Crane Fly, Tipula Oleracea, In Utah, A Van Dyke, Ricardo A. Ramirez, B A. Mcgraw

The known range of the common crane fly (Tipula oleracea L.) is expanding in the western US, as adults were captured (by me) in Utah while emerging and flying over golf course rough. Adults were collected at The Ridge Golf Course in West Valley City on 15 September, 2014, and identified by Dr. Benjamin McGraw at the Pennsylvania State University Turfgrass Entomology Lab in University Park, PA. Crane fly larvae (known as leather jackets for their tough skin) were previously found (again, by me) with the help of golf course superintendent Brian Roth on 4 August, 2012 damaging putting greens …

Water quality monitoring programs across multiple disciplines use total suspended solids (TSS), and volatile suspended solids (VSS), to assess potential impairments of surface water and groundwater. While previous methods for instream filtering have been developed, the need for rapid, cost-effective, high volume sampling has increased with the need to verify and supplement data produced by sondes and instantaneous data loggers. We present an efficient method to filter water instream with a portable drill pump that results in reduced sample processing time, and potentially reduced error associated with sample transportation, preservation, contamination, and homogenization. This technical note outlines the advantages of …

Ecosystem metabolism, that is, gross primary productivity (GPP) and ecosystem respiration (ER), controls organic carbon (OC) cycling in stream and river networks and is expected to vary predictably with network position. However, estimates of metabolism in small streams outnumber those from rivers such that there are limited empirical data comparing metabolism across a range of stream and river sizes. We measured metabolism in 14 rivers (discharge range 14–84 m3 s−1) in the Western and Midwestern United States (US). We estimated GPP, ER, and gas exchange rates using a Lagrangian, 2-station oxygen model solved in a Bayesian framework. GPP ranged from …
Translational Training For Tomorrow’S Environmental Scientists, Mark W. Brunson, Michelle A. Baker
Translational Training For Tomorrow’S Environmental Scientists, Mark W. Brunson, Michelle A. Baker
Biology Faculty Publications
Environmental science exists to seek solutions to problems related to human-nature interactions. Unfortunately, in many cases, environmental research findings are not effectively used because scientists are not able to convey their knowledge effectively to policy makers and the public, and/or because the questions they address are not directly linked to the answers stakeholders need. To address this issue, Schlesinger (2010) called for development of a “translational ecology” that would be understandable and usable by decision-makers, interest groups, and citizens. A barrier to usable science is that researchers are not usually trained to be translational. We convened a multi-disciplinary group of …
Cautions About The Reliability Of Pairwise Gene Correlations Based On Expression Data, Scott Powers, Matt Dejongh, Aaron A. Best, Nathan L. Tintle

Background: Rapid growth in the availability of genome-wide transcript abundance levels through gene expression microarrays and RNAseq promises to provide deep biological insights into the complex, genome-wide transcriptional behavior of single-celled organisms. However, this promise has not yet been fully realized. Results: We find that computation of pairwise gene associations (correlation mutual information) across a set of 2782 total genome-wide expression samples from six diverse bacteria produces unexpectedly large variation in estimates of pairwise gene association regardless of the metric used, the organism under study, or the number and source of the samples. We pinpoint the cause to sampling bias. …

Nutrient transformation processes such as assimilation, dissimilatory transformation, and sorption to sediments are prevalent in benthic zones of headwater streams, but may also occur in the water column. The river continuum concept (RCC) predicts that water column processes become increasingly important with increasing stream size. We predicted that water column nutrient uptake increases with stream size, mirroring carbon/energy dynamics predicted by the RCC. We measured water column uptake of ammonium ( NH+4NH4+ ), nitrate ( NO−3NO3− ), and soluble reactive phosphorus (SRP) in 1st through 5th order stream and river reaches (discharge: 50–68,000 L s−1) in three watersheds ranging from …

Each year, federal and state agencies, including universities, conduct field surveys for invasive species in an attempt to detect new introductions early in the invasion process. National surveys for invasive insects are administered and coordinated by the United States Department of Agriculture's Animal and Plant Health Inspection Service-Plant Protection and Quarantine (USDA-APHIS-PPQ) and the Forest Service through Farm Bill § 10007 ( www.aphis.usda.gov ), the Cooperative Agricultural Pest Survey (CAPS) (caps.ceris.purdue.edu), and Early Detection Rapid Response (EDRR) ( www.fs.fed.us/invasivespecies ) programs. Thousands of traps are placed annually and monitored usually every one to two weeks throughout the U.S., mostly during …
