The reliability of using hair to precisely assess internal mercury burden varies across species, however few studies have assessed the reliability of using claw. We quantified total mercury concentration in internal and keratinous tissues of 55 red foxes (Vulpes vulpes) to compare the performance of hair and claw in predicting internal mercury burden ...

Tree species diversity promotes below‐ground water source partitioning in mixed oak and pine stands, potentially reducing competition for water in more diverse ecosystems. Yet, these results show that it is insufficient to buffer the adverse impacts of severe droughts on above‐ground tree carbon and water use, leading to higher water stress, especially

The authors document spatial variations in tree growth sensitivity to freeze and soil moisture and vapour pressure deficits in Canada. They utilize an extensive multi‐species tree‐ring dataset to create maps representing the strength of relationships (t) between tree basal area increments and these factor for the period 1951–2018, with red indicating ...
