“…Individuals can alter their thermal tolerance through various mechanisms to cope with their thermal environment. However, the type of strategy used or the adaptive value of these strategies will ultimately alter species interactions (Tituskin et al, 2021). Moreover, the community composition and the thermal responses of the species present will feedback on the ability of a given (or target) species to respond to shifts in thermal regimes (Davis et al, 1998b).…”

“…Hence, thermal conditions are likely to alter species interactions creating feedback and cascading loops throughout the ecosystem. Thus, phenotypic plasticity plays an important role in community and population dynamics (Boukal et al, 2019;Tituskin et al, 2021).…”

“…On the contrary, daytime warming had the opposite effects and P. mira retreated to the cooler lower canopy resulting in a spatial mismatch with M. femurrubrum that increased its feeding rates, increasing plant diversity by reducing the competitiveness of dominant plant species (Barton & Schmitz, 2018). Species interactions at the community level are often intricate and one species can influence indirectly the fitness of another via rippling effects mediated by several other species (Berg and Ellers, 2010;Gillespie et al, 2012;Tituskin et al, 2021). In a field study, the co-occurring herbivore species on B. nigra plants affected the distribution of P. xylostella larvae, its parasitism rate and the number of pollinators visiting each plant (Chapter 6).…”

“…Behavioural thermoregulation relates to the behavioural strategies an individual uses to regulate its body temperature, and relies on the capacity to sense and select appropriate thermal environments (Abram et al, 2017). Moreover, in natural settings, the temperature fluctuates periodically (e.g., daily, seasonally, and yearly) and stochastically (e.g., extreme temperature events), influencing all levels of ecological organisation, from individuals to ecosystem functioning (Bond et al, 2021;le Lann et al, 2021;Park, 2019;Speights & Barton, 2019;Tituskin et al, 2021).…”

“…Species are linked by direct and indirect interactions that structure ecological communities. The plastic response of one species is likely to alter the plastic response of the individuals it interacts with (Berg & Ellers, 2010;Boukal et al, 2019;Tituskin et al, 2021). It is therefore essential to assess the effects of the timing of high extreme temperature events on phenotypic plasticity of ectotherms and on their fitness in order to predict population dynamics under variable thermal environments (C.-S. Stoks et al, 2017;Williams et al, 2016;Zhu et al, 2019).…”

A changing world: the role of phenotypic plasticity in host-parasitoid interactions facing extreme temperatures

Climate change alters many environmental parameters, such as temperature or precipitation. The alterations of these environmental parameters have strong consequences for all levels of ecological interactions, from species interactions to community dynamics. Temperature is crucial in determining ecosystem dynamics, especially for ectothermic species such as plants or insects. Phenotypic plasticity, the capacity of one genotype to produce different phenotypes in response to environmental conditions is a common mechanism by which individuals adapt to changing environments and is observed in multiple traits. In response to temperature plasticity is thermodynamically constrained at the molecular level. The capacity of genotypes to adapt to novel environmental conditions plays a crucial role in structuring ecosystem dynamics and species persistence in adverse conditions. Many studies have assessed plant and insect phenotypic plasticity responses to changing thermal conditions, either alone or with their interactions. It is well recognised that temperature in natural ecosystems fluctuates over multiple time scales (e.g., hour, day, season, year). Moreover, these fluctuations can follow predictable or unpredictable patterns, which have different consequences for phenotypic plasticity and ecosystem dynamics. Understanding how and to what extent phenotypic plasticity can track continuously changing environments and its role in structuring species' ecological niches is of utmost importance in the context of rapid climate change. This review discusses the literature on the role of phenotypic plasticity in fluctuating environments, highlighting the role of temporal dynamics. We focus on host-parasitoid interactions because of their importance in driving herbivorous insect populations and their significant representation in ecosystems. Although we discuss literature on phenotypic plasticity at large, this review emphasises the fundamental effects of extreme temperatures in driving biochemical rates underlying phenotypic plasticity.

Climate change alters many environmental parameters with strong consequences for ecological interactions, from species interactions to community dynamics. Temperature is crucial in determining ecosystem dynamics, especially for those involving ectothermic species such as plants or insects. Phenotypic plasticity, the capacity of one genotype to produce different phenotypes in response to environmental conditions, is a common mechanism by which individuals adapt to changing environments and is observed in multiple traits. The capacity of genotypes to adapt to novel temperature conditions plays a crucial role in structuring ecosystem dynamics and species persistence in adverse conditions. It is well recognised that temperature in natural ecosystems fluctuates over multiple time scales (e.g., hour, day, season, year). These fluctuations can follow predictable patterns or be unpredictable, with different consequences for phenotypic plasticity and ecosystem dynamics. Among trophic interactions, host–parasitoid interactions represent a special case because of the intimate symbiosis of the parasitoid larvae with their host. Understanding how and to what extent phenotypic plasticity structures species’ ecological niches is of utmost importance in the context of rapid climate change. With a particular focus on host–parasitoid interactions, this review discusses the literature on the role of phenotypic plasticity in fluctuating environments, highlighting the role of temporal dynamics. While we discuss literature on phenotypic plasticity at large, this review emphasises the fundamental effects of extreme temperatures in driving biochemical rates underlying phenotypic plasticity.

Human alteration of natural environments and habitats is a major driver of species decline. However, a handful of species thrive in human altered environments. The biology, distribution, population structure and molecular adaptations enabling certain species to thrive in human-altered habitats are not well understood. Here, we evaluate the population and functional genomics, niche space and geometric morphometrics of the blue dasher (Pachidiplax longipennis), one of the most ubiquitously observed insects in human altered habitats. We identify a number of genes involved with the success of the blue dasher in human altered habitats. We specifically identify genes contributing to immune function and response to oxidative stress that could be key to the success ofP. longipennisin degraded habitats.Intriguingly, some genes related to these functions are found in regions of high genomic conservation between populations ofP. longipennis, while others are in regions of the genome that are highly structured. Using one of the most robust locality datasets for any species to date, we also generate habitat suitability predictions which show thatP. longipennishas spread with urbanization, as humans have created more suitable habitat for this species. Our work demonstrates thatP. longipenniscould serve as a useful indicator for identifying modified habitats where generalists are pushing out regional specialists. Furthermore, the genes we have putatively identified as associated with the success ofP. longipennisin urban habitats are an important starting point for predicting which species will fare well in the Anthropocene.
