Abstract The late Paleozoic ice age (LPIA) was characterized by persistently low diversity of marine invertebrates following a second-order mass extinction. Here, we used a data set of North American (paleotropical) fossil occurrences of brachiopod, bivalve, and coral genera from the Paleobiology Database, combined with lithologic data from Macrostrat, to demonstrate that low diversity was caused by the collapse of carbonate environments during the LPIA. After dividing the data by lithology, …

This project will contribute to the national need for well-educated scientists, mathematicians, engineers, and technicians by supporting the retention and graduation of high-achieving, low-income students with demonstrated financial need. The project will support students at Juniata College, which serves a high proportion of first generation and low-income students. Over its five-year duration, this project will fund four-year scholarships to 18 students who are pursuing bachelor's degrees in…

It is unclear whether the favorable effects of walnuts on the gut microbiota are attributable to the fatty acids, including α-linolenic acid (ALA), and/or the bioactive compounds and fiber.This study examined between-diet gut bacterial differences in individuals at increased cardiovascular risk following diets that replace SFAs with walnuts or vegetable oils.Forty-two adults at cardiovascular risk were included in a randomized, crossover, controlled-feeding trial that provided a 2-wk standard…

Production of unconventional oil and gas continues to rise, but the effects of high-density hydraulic fracturing (HF) activity near aquatic ecosystems are not fully understood. A commonly used biocide in HF, 2,2-dibromo-3-nitrilopropionamide (DBNPA), was studied in microcosms of HF-impacted (HF+) versus HF-unimpacted (HF-) surface water streams to (i) compare the microbial community response, (ii) investigate DBNPA degradation products based on past HF exposure, and (iii) compare the microbia…

This study investigates whether and how the impact of drivers of aspiration levels changes across the cases of consistent and inconsistent performance feedback within the context of a retailer. Analysis of internal corporate data shows that while past aspiration level and performance–aspiration gap positively influence the current aspiration level in the case of inconsistent feedback, performance feedback consistency changes only the impact of performance relative to peers. This study replica…

We have prepared nine structural isomers of a tetrakis(arylethynyl)benzene chromophore functionalized with 4-butoxyphenyl and pyridyl units as the respective donor and acceptor units and examined their steady-state spectroscopic parameters to study how small structural variations effect the electronic absorption and emission spectra. Unlike their 4-dibutylaminophenyl congeners that exhibited dynamic hypsochromic or bathochromic shifts in response to Lewis and Brønsted acids, the current class…

The sustainability of the human race depends on finding the natural resources necessary to maintain the built infrastructure of the developed world and to build capacity in developing countries. Metals such as iron, copper and gold are among the most important natural resources used by society as they are embedded throughout our built environment. Iron is used to make steel. Copper is used to generate electricity, and copper and gold are used to move electrical current through all electronic …

There has been no prior application of matched metagenomics and metatranscriptomics in infection (CDI) evaluating the role of fungi in CDI or identifying community functions that contribute to the development of this disease. We collected diarrheal stools from 49 inpatients (18 of whom tested positive for CDI) under stringent inclusion criteria. We utilized a tiered sequencing approach to identify enriched bacterial and fungal taxa, using 16S and internal transcribed spacer (ITS) rRNA gene am…

Metabolic rates are fundamental to many biological processes, and commonly scale with body size with an exponent ( b) between 2/3 and 1 for reasons still debated. According to the 'metabolic-level boundaries hypothesis', b depends on the metabolic level ( L). We test this prediction and show that across cephalopod species intraspecific b correlates positively with not only L but also the scaling of body surface area with body mass. Cephalopod species with high L maintain near constant mass-sp…

Novel culture independent technologies have further elucidated the composition of the human mycobiome, though the role of fungi in human health and disease remains largely unknown. Recent studies have suggested conflicting roles for fungi in the gastrointestinal tract, underscoring the complexity of the interactions between the mycobiome, its bacterial counterpart, and the host. One key example is the observation that fungal taxa are overrepresented in patients with Clostridioides difficile i…
