A comparison of honey bee-collected pollen from working agricultural lands using light microscopy and ITS metabarcoding
Taxonomic identification of pollen has historically been accomplished via light microscopy but requires specialized knowledge and reference collections, particularly when identification to lower taxonomic levels is necessary. Recently, next-generation sequencing technology has been used as a cost-effective alternative for identifying bee-collected pollen; however, this novel approach has not beenAuthorsMatthew Smart, Robert S. Cornman, Deborah D. Iwanowicz, Margaret McDermott-Kubeczko, Jeff S Pettis, Marla S Spivak, Clint R.V. OttoComplete genome sequence of a novel aquareovirus that infects the endangered fountain darter, Etheostoma fonticola
Here, we report the complete genome of a novel aquareovirus isolated from clinically normal fountain darters, Etheostoma fonticola, inhabiting the San Marcos River, Texas, USA. The complete genome consists of 23,958 bp consisting of 11 segments that range from 783 bp (S11) to 3,866 bp (S1).AuthorsLuke R. Iwanowicz, Deborah D. Iwanowicz, Cynthia R. Adams, Teresa D.

Environmental studies increasingly identify the presence of both contaminants of emerging concern (CECs) and legacy contaminants in aquatic environments; however, the biological effects of these compounds on resident fishes remain largely unknown. High throughput methodologies were employed to establish partial transcriptomes for three wild-caught, non-model fish species; smallmouth bass (MicropteAuthorsCassidy M. Hahn, Luke R.

Species detection using environmental DNA (eDNA) has tremendous potential for contributing to the understanding of the ecology and conservation of aquatic species. Detecting species using eDNA methods, rather than directly sampling the organisms, can reduce impacts on sensitive species and increase the power of field surveys for rare and elusive species. The sensitivity of eDNA methods, however, rAuthorsCaren S. Goldberg, Cameron R. Turner, Kristy Deiner, Katy E. Klymus, Philip Francis Thomsen, Melanie A. Murphy, Stephen F. Spear, Anna McKee, Sara J.

Understanding the diet of an endangered species illuminates the animal’s ecology, habitat requirements, and conservation needs. However, direct observation of diet can be difficult, particularly for small, nocturnal animals such as the Pacific pocket mouse (Heteromyidae: Perognathus longimembris pacificus). Very little is known of the dietary habits of this federally endangered rodent, hindering mAuthorsDeborah D. Iwanowicz, Amy G. Vandergast, Robert S. Cornman, Cynthia R. Adams, Joshua R.

As pollinators, bees are cornerstones for terrestrial ecosystem stability and key components in agricultural productivity. All animals, including bees, are associated with a diverse community of microbes, commonly referred to as the microbiome. The bee microbiome is likely to be a crucial factor affecting host health.

AuthorsRobert S. Cornman, Clint R.V. Otto, Deborah D. Iwanowicz, Jeffery S PettisZ chromosome divergence, polymorphism and relative effective population size in a genus of lekking birds
Sex chromosomes contribute disproportionately to species boundaries as they diverge faster than autosomes and often have reduced diversity. Their hemizygous nature contributes to faster divergence and reduced diversity, as do some types of selection. In birds, other factors (mating system and bottlenecks) can further decrease the effective population size of Z-linked loci and accelerate divergenceAuthorsSara J. Oyler-McCance, Robert S. Cornman, Kenneth L. Jones, Jennifer A. FikeCharacterization of a novel hepadnavirus in the white sucker (Catostomus commersonii) from the Great Lakes Region of the USA
The white sucker Catostomus commersonii is a freshwater teleost often utilized as a resident sentinel. Here, we sequenced the full genome of a hepatitis B-like virus that infects white suckers from the Great Lakes Region of the USA. Dideoxysequencing confirmed the white sucker hepatitis B virus (WSHBV) has a circular genome (3542 bp) with the prototypical codon organization of hepadnaviruses. ElecAuthorsCassidy M. Hahn, Luke R.

Sage-grouse are iconic, declining inhabitants of sagebrush habitats in western North America, and their management depends on an understanding of genetic variation across the landscape. Two distinct species of sage-grouse have been recognized, Greater (Centrocercus urophasianus) and Gunnison sage-grouse (C. minimus), based on morphology, behavior, and variation at neutral genetic markers.

Mussels are useful indicator species of environmental stress and degradation, and the global decline in freshwater mussel diversity and abundance is of conservation concern. Elliptio complanata is a common freshwater mussel of eastern North America that can serve both as an indicator and as an experimental model for understanding mussel physiology and genetics.

We developed genetic resources for two North American frogs, Lithobates clamitans and Pseudacris regilla, widespread native amphibians that are potential indicator species of environmental health. For both species, mRNA from multiple tissues was sequenced using 454 technology. De novo assemblies with Mira3 resulted in 50 238 contigs (N50 = 687 bp) and 48 213 contigs (N50 = 686 bp) for L. clamitansAuthorsLaura S. Robertson, Robert S. Cornman - News
