Potential for DNA-based identification of Great Lakes fauna: match and mismatch between taxa inventories and DNA barcode libraries
DNA-based identification of mixed-organism samples offers the potential to greatly reduce the need for resource-intensive morphological identification, which would be of value both to bioassessmentExpand

Sex association and synonymy in southwestern U.S. species of Dasymutilla (Hymenoptera: Mutillidae)
Species of the velvet ant genus Dasymutilla exhibit extreme sexual dimorphism and many are known from only one sex. Several sets of species from the southwestern U.S. have been suspected of beingExpand

Addressing the Dasymutilla quadriguttata Species-Group and Species-Complex (Hymenoptera: Mutillidae): Several Distinct Species or a Single, Morphologically Variable Species?
Abstract This study uses morphological and natural history data, along with molecular data derived from the internal transcribed spacers 1 and 2 (ITS1 and ITS2), to investigate the status of speciesExpand

Genetic structure of the benthic amphipod Diporeia (Amphipoda: Pontoporeiidae) and its relationship to abundance in Lake Superior
The freshwater amphipod Diporeia is a crucial part of the food web in the Laurentian Great Lakes, but has faced serious declines correlated with the invasion of zebra mussels (Dreissena polymorpha),Expand

Evaluating Ethanol-based Sample Preservation to Facilitate Use of DNA Barcoding in Routine Freshwater Biomonitoring Programs Using Benthic Macroinvertebrates
Molecular methods, such as DNA barcoding, have the potential to enhance biomonitoring programs worldwide. Altering routinely used sample preservation methods to protect DNA from degradation may poseExpand

Ballast Water Exchange and Invasion Risk Posed by Intracoastal Vessel Traffic: An Evaluation Using High Throughput Sequencing.
Ballast water remains a potent vector of non-native aquatic species introductions, despite increased global efforts to reduce risk of ballast water mediated invasions. This is particularly true ofExpand

A Molecular Method for Associating the Dimorphic Sexes of Velvet Ants (Hymenoptera: Mutillidae)
Abstract For several groups of insects, including the velvet ants, male–female associations are difficult because of extreme dimorphism between the sexes. Many species, or even genera, are known fromExpand
