Fossil insect folivory tracks paleotemperature for six million years

Abstract: Abstract. Paleoecological studies enhance our understanding of biotic response to climate change because they consider timescales not accessible through laboratory or ecological studies. From 60 to 51 million years ago (Ma), global temperatures gradually warmed to the greatest sustained highs of the last 65 million years. Superimposed on this gradual warming is a transient spike of high temperature and pCO 2 (partial pressure of carbon dioxide in the atmosphere; the Paleocene-Eocene Thermal Maximum 55.8 Ma) an… Show more

“…First, higher temperatures may accelerate insect population growth rates, potentially increasing the frequency and severity of plant damage (Liu et al, 2011;Mitton and Ferrenberg, 2012). Indeed, foliar damage from insect herbivores increased dramatically with mean annual temperature across millions of years in the fossil record (Currano et al, 2010). Warmer winter temperatures also may reduce overwinter mortality among herbivores (Bale et al, 2002) and increase foraging opportunities during prolonged growing seasons (Brodie et al, 2012).…”

“…However, this relationship has not been systematically addressed, and the consistent correlation in the fossil record of total and endophytic DTR strongly suggests that it may be significant [3], [9]. The few actualistic studies of insect-damaged leaves to date, while helpful, did not include insect sampling [26], [27].…”

“…Long-term projects with multiple colleagues were initiated to examine diverse preangiospermous, gymnosperm-dominated floras (Labandeira 2006;Ding et al 2014). Current preliminary studies of Mesozoic herbivory use a similar methodology as those for the early Permian (Labandeira and Allen 2007;Schachat et al 2014), the CretaceousPaleogene (K-Pg) boundary Wilf et al 2006), and the mid-Paleogene climate events (Wilf et al 2005;Wappler et al 2012;Currano et al 2009). In addition, studies of mid-Mesozoic pollination have centered principally on the preangiospermous mid-Mesozoic (Ren et al 2009;Labandeira 2010;Peñalver et al 2012).…”
