Tracking Long‐Term Trends in Sockeye Salmon <i>(Oncorhynchus nerka)</i> Population Dynamics Using Sterol and Stanol Biomarkers in Lake Sediments Open
We analyzed biomarkers, including sterols, stanols, and δ 15 N, in sediment cores from lakes with well‐documented sockeye salmon return histories. Our goal was to improve estimates of past changes in salmon escapement, that is, the populat…

A 2200-year record of Andean Condor diet and nest site usage reflects natural and anthropogenic stressors Open
Understanding how animals respond to large-scale environmental changes is difficult to achieve because monitoring data are rarely available for more than the past few decades, if at all. Here, we demonstrate how a variety of palaeoecologic…

Can Chitin and Chitosan Replace the Lichen Evernia prunastri for Environmental Biomonitoring of Cu and Zn Air Contamination? Open
This study compared the ability of the lichen Evernia prunastri, chitin and chitosan to take up Cu2+ and Zn2+. It was hypothesized that chitin and chitosan have an accumulation capacity comparable to the lichen, so that these biopolymers c…
