Half a century of thermal tolerance studies in springtails (Collembola): A review of metrics, spatial and temporal trends

“…This information is important when measuring thermal tolerance data because some authors have found that surface living species have greater heat tolerance than soil living species ( Van Dooremalen et al., 2013 ; Pallarés et al., 2019 ). Local microclimate and other microhabitat conditions are also key factors that can modify thermal tolerance between different populations ( Kutcherov et al., 2020 ; Liefting and Ellers, 2008 ), affecting spatial patterns on a large scale ( Sengupta et al., 2016 ; Sengupta et al., 2017 ). In this way, some recent works on the effects of global warming on hexapod populations have emphasized its importance, including data on Collembola ( Tüzün and Stoks, 2018 ; Verheyen et al., 2019 ).…”

“…Second, thermal tolerance studies could be increased for those families that are less represented in order to reach a representative balance the knowledge in this group of edaphic animals. Third, it is important to incorporate local microclimatic effects to characterize the true exposure levels that different populations experience in the field and relate them to thermal tolerances obtained under laboratory experiments [see ( Kutcherov et al., 2020 ; Liefting and Ellers, 2008 )].…”

Intra and interspecific differences in desiccation tolerance in native and alien Antarctic springtails in geothermal grounds

“…Regarding other physiological traits, there are studies indicating that the heat produced in GA may favor local thermal adaptation for some species (Pastenes et al, 2017;Schott & Brusven, 1980). However, to date no physiological differences have been found in springtails in these environments, with only one study on thermal tolerance (Kutcherov et al, 2020).…”

Trait‐mediated responses to aridity and experimental drought by springtail communities across Europe

“…To move Even though the only example with a springtail species reported some degree of ontogenetic plasticity (i.e. steeper reaction norms of developmental rates of juveniles than those of adults), there was almost no sign of local adaptation to geothermal warming (Kutcherov et al, 2020). If so, this calls for urgent studies assessing the adaptive potential of springtails, and more generally tracking population dynamics and functional trait shifts at a community level (Bardgett & van der Putten, 2014;Berg et al, 2010;Guerra et al, 2021).…”
