December 2024 in “Institutional Repositories DataBase (IRDB)” In this study, the authors found that the shoulder guard hair of captive sika deer most accurately reflects dietary information during winter coat growth, useful for analyzing wild deer hair samples.
October 2024 in “Rapid Communications in Mass Spectrometry” This study suggests that the shoulder guard hair of captive sika deer is effective for hair analysis, providing insights into growth patterns and isotopic changes that could aid future research on wild deer using hair samples.
