CHANGES IN THE DISTRIBUTION OF NESTING ARCTIC SEADUCKS ARE NOT STRONGLY RELATED TO VARIATION IN POLAR BEAR PRESENCE

Changes in the distribution of nesting Arctic seaducks are not strongly related to variation in polar bear presence

Accessories Contemporary climate change is predicted to expose some species to altered predation regimes.Losses of Arctic sea ice are causing polar bears to increasingly forage on colonial seaduck eggs in lieu of ice-based hunting of marine mammals.Although polar bear predation of bird eggs has now been widely documented, it is unclear whether this

Strategy for Screening of Antioxidant Compounds from Two Ulmaceae Species Based on Liquid Chromatography-Mass Spectrometry

Liquid chromatography-mass spectrometry (LC-MS)-based untargeted metabolomics implies that annotated metabolites can serve as potential markers of the associated bioactivities of plant extracts.Firstly, we selected Aphananthe aspera and Zelkova serrata (Family: Ulmaceae) from 16 Korean plant species based on their distinct principal component analy
