A genomic tool to tackle cryptic diversity demonstrates the potential for off-target use of GT-seq panels A genomic tool to tackle cryptic diversity demonstrates the potential for off-target use of GT-seq panels
A comprehensive understanding of life history is vital to successful species conservation and management. When different life history stages are accompanied by considerable morphological or cryptic variation, such as the egg and larval phases exhibited by most fishes, genomic tools are essential for identifying species so that early-life ecology questions can be studied. Genotyping-in...
Availability of dark daytime refuge may limit mysid abundance in the Laurentian Great Lakes Availability of dark daytime refuge may limit mysid abundance in the Laurentian Great Lakes
The zooplankton Mysis diluviana is a major component of the Laurentian Great Lakes food web and has recently declined in abundance in both lakes Michigan and Huron. Drivers of these declines are not well understood. Here, we explore the hypothesis that recent increases in water clarity have contributed to the decline of M. diluviana (mysids) by limiting the availability of daytime dark...
On the importance of ichthyoplankton monitoring for invasive grass carp control in the Laurentian Great Lakes On the importance of ichthyoplankton monitoring for invasive grass carp control in the Laurentian Great Lakes
Grass carp (Ctenopharyngodon idella) is an invasive herbivore observed in small numbers in the Laurentian Great Lakes since the 1980 s with records from all lakes except Lake Superior. Identification of diploid, age-1 + grass carp from the Sandusky River, a Lake Erie tributary, in 2012, prompted targeted efforts to evaluate the status of grass carp reproduction in the Lake Erie Basin. In...
