“…In many ways, variation in performance curves of N. crassa is quite typical for many ectotherms that have been studied (Sinclair et al ., 2016). Most genetic variation in N. crassa is variation in performance curve elevation, which contrasts with previous studies in other species that have found most variation to be for reaction norm shapes (Izem and Kingsolver, 2005; Logan et al ., 2019). Yet variation in tolerance curve elevation is commonly found, a review of thermal performance curves in insects found that elevation shifts were the most common type of change along environmental gradients (Tüzün and Stoks, 2018), see also Scheiner (1993).…”

“…In these studies, the genetic variance-covariance matrix (G-matrix) for thermal performance across several temperatures has been estimated, and how genetic variation is aligned with characteristic directions of reaction norm evolution has been determined (e.g. Izem and Kingsolver, 2005; Logan et al ., 2019). This is essential in order to explore how freely thermal performance can evolve in different environments, and to quantify if thermal performance evolution is bound to follow a certain evolutionary path or performance curve shape.…”

1Earth's temperature is increasing due to anthropogenic CO 2 emissions; and organ-2 isms need either to adapt to higher temperatures, migrate into colder areas, or face 3 extinction. Temperature affects nearly all aspects of organism's physiology via its in-4 fluence on metabolic rate and protein structure. Compared to other abiotic stresses, 5 genetic adaptation to increased temperature may be much harder to achieve due to sys-6 temic effects of temperature. As the evolutionary potential for adaptation to higher 7 temperatures is relatively unknown, we studied the quantitative genetics of thermal 8 performance curves of the fungal model system Neurospora crassa. We asked whether 9 there is genetic variation for thermal performance curves and examined possible ge-10 netic of evolution constraints by estimating the G-matrix. We observed substantial 11 amount of genetic variation for growth in different temperatures, and most genetic 12 variation was for performance curve elevation. Contrary to common theoretical as-13 sumptions we did not find strong evidence for genetic trade-offs for growth between 14 hotter and colder temperatures. We also simulated short term evolution of thermal per-15 formance curves of N. crassa, and suggest that they can have versatile responses to 16 selection. 17 Earth's temperature is rising due to anthropogenic activities (IPCC, 2013). The challenge most 19 organisms will face in a warming world is that they have to either adapt to warmer conditions or 20 migrate into colder areas to avoid extinction (Deutsch et al., 2008; Dillon et al., 2010; Araújo et al., 21 2013; Merilä and Hendry, 2014). Temperature is a unique abiotic stress, because the kinetics of 22 all biochemical reactions and protein stability are affected by temperature. As such, temperature 23 influences nearly all aspects of an ectothermic organism's physiology (Schulte, 2015; Arcus et al., 24 2016). Therefore, adapting to a higher temperature may be much more difficult than adapting to 25 a more specific environmental stress. For some anthropogenic stresses, such as antibiotics or her-26 bicides, decades of research have revealed strong evolutionary adaptation to these stresses (Davies 27 and Davies, 2010; Powles and Yu, 2010). However, genetic basis of adaptation to temperature is 28 likely to much more complex (Hochachka and Somero, 2002). 29According to quantitative genetic theory, evolution is possible if variation in a trait is heritable 30 and selection acts on this variation. However, the evolution of multivariate traits can be complicated 31 by genetic correlations, allowing evolution to proceed only in few directions or possibly preventing 32 it altogether (Walsh and Blows, 2009). The more entangled traits are with each other, the more 33 difficult the evolution of the underlying genetic network and the phenotype can be. 34The ability of an organism to tolerate different temperatures is often described by thermal per-35 formance curve (Huey and Kingsolver, 1989, 1993), which describes the fitn...

“…Canopy-dwelling tropical ants are known to behaviourally circumvent high temperature areas encountered while foraging, avoiding temperatures 5-10C below their thermal tolerance limits (Logan et al, 2019;Spicer et al, 2017). Thus, these butterflies and other high-altitude species must adapt their flying times and/or behaviours during hot periods, which could have cascading effects on fitness.…”

“…Adaptation to novel niches has been widely studied in the context of invasive species that colonize and adapt to unfamiliar environments (Davis 2009, MacDougall et al 2009, Logan et al 2019). However, the ongoing refinement of traits that provide access to novel niches has received little attention, probably because most evolutionary novelties (and associated niche discoveries) occurred in the distant past and are therefore difficult to study.…”

Evolutionary innovations allow populations to colonize new, previously inaccessible ecological niches. We previously reported that aerobic growth on citrate (Cit + ) evolved in a population of Escherichia coli during adaptation to a minimal glucose medium containing citrate (DM25). Cit + can grow in citrate-only medium (DM0), which is a novel environment for E. coli. To study adaptation to this new niche, we evolved one set of Cit + populations for 2,500 generations in DM0 and a control set in DM25. We identified numerous parallel mutations, many mediated by transposable elements. Several lineages evolved multi-copy amplifications containing the maeA gene, constituting up to ~15% of the genome. We also found substantial cell death in ancestral and evolved clones. Our results demonstrate the importance of copy-number variation and transposable elements in the refinement of the Cit + trait. However, the observed mortality suggests a persistent evolutionary mismatch between E. coli physiology and a citrate-only environment.
