This work is part of a study investigating the movement of microcystin from aquatic to terrestrial ecosystems via trophic transfer. Little brown bats (Myotis lucifugus), feeding opportunistically on aquatic insects including Hexagenia mayflies, were collected from a maternity roost near Little Traverse Lake (Leelanau County, Michigan, USA). Bats and fecal samples were collected for dietary analysis, quantification of microcystin in livers and feces, and histopathological evaluation of the liver. Liver was collected in RNAlater and stored frozen. Livers from three bats with the highest microcystin levels by ELISA were thawed, washed with PBS, fixed in 10% neutral buffered formalin, processed routinely for histopathology,...

Diet and estimated ages of Silver Chub (Macrhybopsis storeriana) collected by the US Geological Survey in western Lake Erie in 2014 are presented. Fish were frozen in the field at -20 C and dissected in the lab. Ages were estimated by one experienced biologist who estimated ages twice, then reconciled age estimates when the two age estimates differed. Diet taxa were enumerated, dried individually at 60 F until stable weight was achieved (~24-48 hrs), then weighed. Zero weights for non-zero counts indicates dry weight was below detection limit of the scale used.
