TL;DR: The prevalence of testicular oocytes is discussed in terms of human population and agricultural intensity and the number of histologic sections needed to accurately detect the condition in mature smallmouth bass was statistically evaluated.

TL;DR: Smallmouth bass were the only species in which testicular oocytes were observed; however, measurable concentrations of plasma vitellogenin were found in male bass and white sucker, with the highest prevalence and severity in bass collected in the Susquehanna drainage.

TL;DR: Comparing pollen identification results derived from light microscopy and DNA sequencing techniques with samples collected from honey bee colonies embedded within a gradient of intensive agricultural landscapes in the Northern Great Plains throughout the 2010–2011 growing seasons shows that DNA sequencing is an appropriate, and enhancing, substitutive technique for accurately capturing the breadth of bee-collected species of pollen present across agricultural landscapes.

TL;DR: The findings indicate that selected sensitive species may be stressed by multiple factors and constantly close to the threshold between a sustainable (healthy) and nonsustainable (unhealthy) condition.

TL;DR: The results show that a pre-compiled, curated reference database is not essential for genus- level assignments, but species-level assignments are hindered by database gaps, reference length variation, and probable errors in the taxonomic assignment, requiring post-hoc evaluation.
