“…The chronosequence approach assumes that, for a sequence of sites (in this case, moraines) with similar characteristics such as topography, climate, and parent material on which the soil was formed, time can be treated as the only variable. It is well known that the application of this chronosequence concept has some limitations, as landscape development is much more complex (Wojcik et al, 2021).…”

“…Macronutrient contents of subglacial sediments exposed by deglaciation are likely major controls on ecological succession in new proglacial areas (Nemergut et al., 2007; Rime et al., 2015; Wojcik et al., 2021); the sampled subglacial sediments contained relatively high amounts of P, including its readily bioavailable fractions, in contrast to the low amounts of mostly recalcitrant C and N detected. This corroborates the results of previous studies that found glaciers to be associated with high fluxes of crustal nutrients, including P, released from glacial comminution and chemical weathering of bedrock (Hawkings et al., 2015, 2016; Hodson et al., 2004; Wadham et al., 2010).…”

“…Glaciers and ice sheets are shrinking rapidly as a consequence of climate warming, especially in the Arctic where the surface air temperature has increased twice the global average in the last two decades (Meredith et al., 2019). Accelerating glacier recession, inevitable in the coming decades (Bosson et al., 2019; Hugonnet et al., 2021; Zemp et al., 2019), is causing large and irreversible changes to Arctic ecosystems, including the loss of biodiversity and function associated with glacial habitats (Cauvy‐Fraunié & Dangles, 2019; Stibal et al., 2020) and the transition of vast areas of subglacial environment to proglacial habitats subject to rapid ecological succession (Bernasconi et al., 2011; Wojcik et al., 2021). While post‐glacial ecosystem development is largely dependent on allochthonous materials (Rime et al., 2016), the subglacial legacy is likely important as a “starter pack” containing labile crustal nutrients (Hawkings et al., 2014, 2016, 2020; Hatton et al., 2019; Urra et al., 2019), nitrogen (Lawson, Bhatia, et al., 2014; Martin et al., 2020), organic carbon (OC) substrates (Hood et al., 2009; Lawson, Wadham, et al., 2014; Stibal, Wadham, et al., 2012; Wadham et al., 2019), and microbial inocula (Bradley et al., 2016; Řeháková et al., 2010; Rime et al., 2016).…”
