Andrew L. Von Duyke, David C. Douglas, Jason K Herreman, Justin A. Crawford
2020, Ecology and Evolution (10) 5595-5616
Continued Arctic warming and sea-ice loss will have important implications for the conservation of ringed seals, a highly ice-dependent species. A better understanding of their spatial ecology will help characterize emerging ecological trends and inform management decisions. We deployed satellite transmitters on ringed seals in the summers of 2011, 2014,...
Spatial population structure of a widespread aquatic insect in the Colorado River Basin: Evidence for a Hydropsyche oslari species complex
Anya N. Metcalfe, Theodore A. Kennedy, Jane C. Marks, Aaron D. Smith, Jeffrey D. Muehlbauer
2020, Freshwater Science (39) 309-320
Structural connectivity and dispersal ability are important constraints on functional connectivity among populations. For aquatic organisms that disperse among stream corridors, the regional structure of a river network can, thus, define the boundaries of gene flow. In this study, we used mitochondrial DNA (mtCO1 barcoding gene) to examine the genetic...

Are environmental DNA methods ready for aquatic invasive species management?
Adam J. Sepulveda, Nanette M Nelson, Christopher L. Jerde, Gordon Luikart
2020, Trends in Ecology and Evolution (35) 668-678
Multiple studies have demonstrated environmental (e)DNA detections of rare, invasive species. However, invasive species managers struggle with using eDNA results because detections might not indicate species presence. We evaluated if eDNA methods have matured to a point where they can be widely applied to aquatic invasive species management. We found...
