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

Thermal tolerance responses of the two-spotted stink bug, Bathycoelia distincta (Hemiptera: Pentatomidae), vary with life stage and the sex of adults

“…Using different ramping may yield different results (Terblanche et al, 2008). However, the current study used a slower ramping rate of 0.2 min − 1 because of its ecological relevance (Escribano-Álvarez et al, 2022). Furthermore, Chown et al, (2009) and Terblanche et al, (2006) showed that slower ramping rates may result in more plasticity, though the opposite might be the case for other organisms (Terblanche et al, 2007).…”

“…CTLs are ecologically relevant because they can resemble natural environmental conditions through gradual ramping of temperature (Terblanche et al, 2007). Slow ramping rates (less than 0.5 min − 1 ) are considered more ecological as compared to very slow ramping rates (less than 0.1 min − 1 ), which would result in the hardening of organisms (Escribano-Álvarez et al, 2022;Terblanche et al, 2007;Worland, 2005). CTLs have been used to investigate the thermal fitness, sensitivity, and vulnerability to extreme temperatures of insects (Horne et al, 2019;Nyamukondiwa et al, 2018;Jiranan Piyaphongkul, Pritchard, and Bale 2012).…”

Colonizing polar environments: thermal niche evolution in Collembola

“…Critical thermal limits (CTL) of a total of 65 species of springtails (Collembola) were retrieved from the review by Escribano‐Álvarez et al (2022). CT max and CT min are classic measurements of physiological thermal tolerance (Cowles and Bogert 1944, Terblanche et al 2007), as well as a relevant metric in studies aimed to address climate change impacts in ectotherms (Deutsch et al 2008, Clusella‐Trullas et al 2021).…”

“…A recent global‐extent scientific review has detected that there is a bias towards the study of thermal tolerances of springtails from cold and polar regions, compared to the less studied tropical species (Escribano‐Álvarez et al 2022). The soils of polar environments, such as those of Antarctica, are subject to strong freezing and thawing process of the ice‐sheets (Blume et al 2002), which in turn leads to low‐diversity edaphic ecosystems (Convey 2001).…”

The Resilience of Polar Collembola (Springtails) in a Changing Climate

“…Collembola can rapidly increase their heat tolerance through the heat shock response, largely mediated by heat shock proteins ( Escribano-Álvarez et al., 2022 ; Sørensen et al., 2003 ). For example, heat survival of Orchesella cincta increases by >60 % after only an hour at 35°C ( Bahrndorff et al., 2009 ).…”
