At the end of February 2020, scientists as well as EPA representatives managing or participating in the GLRI Barcoding Initiative project gathered at Cornell Biological Field Station to share updates with the group.
Oneida Lake is New York State’s 3rd most heavily fished lake. Walleye have historically received the majority of targeted effort, with black bass increasing in importance in recent years. Long-term monitoring of the fisheries and limnology of Oneida Lake has captured a series of changes in recent decades that have resulted in pronounced changes in the lake’s physical and biological characteristics, including reductions in nutrient inputs resulting from the Great Lakes Basin water quality agreements; establishment of invasive dreissenid mussels resulting in increases in water clarity; increases in summer water temperatures and decreases in duration of ice cover; establishment of a breeding population of double-crested cormorants; and increases in populations of white perch and gizzard shad.
Congratulations to recent Cornell Biological Field Station intern Anna Poslednik ’21 in receiving the Goldwater Scholarship. The Goldwater Scholarship is one of the most prestigious awards available to sophomores and juniors across U.S. colleges who show exceptional promise in the fields of science, mathematics and engineering.
As one of the selected 396 recipients from approximately 5,000 nominees, she will receive up to $7,500 to cover expenses like tuition, books and room and board for her senior year. As part of the selection process, colleges nominate up to four students who intend to pursue a career in research and have at least a 3.0 GPA.
Anna first started her research at her summer 2019 internship guided by Postdoc Tom Evans and Senior Research Associate Randy Jackson. The following is an excerpt taken from the Cornell Daily Sun.
We wanted to know if rapid evolution in nature by an ecologically important species alters the temporal dynamics of its community. Changes in genetically based traits critical to the strengths of ecological interactions, taking place on the order of a few generations, have been repeatedly found in a diversity of natural populations.
(July 25, 2019) A new paper published in the Journal of Great Lakes Research, authored by U.S. EPA contract scientists Rick Barbiero and Barry Lesht and Cornell University researchers Lars Rudstam and Jim Watkins, offers an unprecedented look at zooplankton communities across the Great Lakes during a period of great change in the lakes.
Last week, researchers at the Cornell University Biological Field Station may have set a new mark
for the largest fish ever recorded from Oneida Lake. A netting survey for lake sturgeon resulted in
the tagging and release of a 139 pound sturgeon, the largest sturgeon handled since the sturgeon
netting survey began 17 years ago in 2002, and possibly the largest fish ever documented in Oneida Lake.
