“…In fish, a sudden drop in temperature diminishes the production of immune cellular and molecular resources, impairs T cell-dependent immune responses and may led to cellular inactivation or anergy (40–42). High temperatures correlate with enhanced parasite transmission and resilience within hosts' bodies (43, 44), even when the onset of behavioral fever may stimulate phagocytic activation and modulate innate humoral responses (45). In fish, shifting too far away from thermopreferendum wakes up distress-induced genes and alters the responsiveness of HPI and immune axis (46), but the overall effect may be modulated by acclimation to temperature changes (42).…”

Netting the Stress Responses in Fish

In the last decade, the concept of animal stress has been stressed thin to accommodate the effects of short-term changes in cell and tissue physiology, major behavioral syndromes in individuals and ecological disturbances in populations. Seyle's definition of stress as “the nonspecific (common) result of any demand upon the body” now encompasses homeostasis in a broader sense, including all the hierarchical levels in a networked biological system. The heterogeneity of stress responses thus varies within individuals, and stressors become multimodal in terms of typology, source and effects, as well as the responses that each individual elicits to cope with the disturbance. In fish, the time course of changes after stress strongly depends on several factors, including the stressful experiences in early life, the vertical transmission of stressful-prone phenotypes, the degree of individual phenotypic plasticity, the robustness and variety of the epigenetic network related to environmentally induced changes, and the intrinsic behavioral responses (individuality/personality) of each individual. The hierarchical heterogeneity of stress responses demands a code that may decrypt and simplify the analysis of both proximate and evolutionary causes of a particular stress phenotype. We propose an analytical framework, the stressotope , defined as an adaptive scenario dominated by common environmental selective pressures that elicit common multilevel acute stress-induced responses and produce a measurable allostatic load in the organism. The stressotope may constitute a blueprint of embedded interactions between stress-related variations in cell states, molecular mediators and systemic networks, a map of circuits that reflect the inherited and acquired stress responses in an ever-changing, microorganismal-loaded medium. Several features of the proposed model are discussed as a starting point to pin down the maximum common stress responses across immune-neuroendocrine relevant physiological levels and scenarios, including the characterization of behavioral responses, in fish.

“…Symbionts, ranging from mutualists to parasites, may further influence their hosts' T p which can lead to complex eco‐evolutionary dynamics (Corbin et al, 2017; de Roode & Lefèvre, 2012; Żbikowska & Cichy, 2015). Ectothermic hosts, for example, can shift their T p to higher temperatures (‘behavioural fever’; Kluger, 1979; Thomas & Blanford, 2003) or lower temperatures (‘behavioural anapyrexia’; Fedorka et al, 2016; Moore & Freehling, 2002; Müller & Paul, 1993) as a form of self‐medication by moving to thermal environments outside the optimum of their parasitic symbiont.…”

Temperature plays a fundamental role in the fitness of all organisms. In particular, it strongly affects metabolism and reproduction in ectotherms that have limited physiological capabilities to regulate their body temperature. The influence of temperature variation on the physiology and behaviour of ectotherms is well studied but we still know little about the influence of symbiotic interactions on thermal preference (Tp) of the host. A growing number of studies focusing on the Wolbachia‐Drosophila host‐symbiont system found that Wolbachia can influence Tp in Drosophila laboratory strains. Here, we investigated the effect of Wolbachia on Tp in wild‐type D. melanogaster flies recently collected from nature. Consistent with previous data, we found reduced Tp compared to an uninfected control in one of two fly strains infected with the wMelCS Wolbachia type. Additionally, we, for the first time, found that Wolbachia titer variation influences the thermal preference of the host fly. These data indicate that the interaction of Wolbachia and Drosophila resulting in behavioural variation is strongly influenced by the genetic background of the host and symbiont. More studies are needed to better understand the evolutionary significance of Tp variation influenced by Wolbachia in natural Drosophila populations.

Temperature plays a fundamental role for the fitness of all organisms. In particular, it strongly affects metabolism and reproduction in ectotherms that have limited physiological capabilities to regulate their body temperature. Ectotherms thus have to maintain thermal homeostasis by behavioral adjustments. The influence of temperature variation on the physiology and behavior of ectotherms is well studied but we still know little about the influence of symbiotic interactions on thermal preference (Tp) of the host. The Wolbachia-Drosophila host-symbiont system represents an ideal model for addressing these questions. A growing number of studies demonstrated that different Wolbachia types can influence Tp in different Drosophila species, but these results may be confounded by the use of long-term Drosophila lab-strains that may not be representative for natural fly populations. To account for this, we investigated the effect of Wolbachia on Tp in wild-type D. melanogaster flies recently collected from nature. Consistent with previous data, we found reduced Tp compared to an uninfected control in one of two fly strains infected with the wMelCS Wolbachia type. Additionally, we, for the first time, found that Wolbachia titer variation influences thermal preference of the host fly. These data indicate that the interaction of Wolbachia and Drosophila resulting in behavioral variation is complex and strongly influenced by the genetic background of host and symbiont. Our results further emphasize the necessity for more in-depth studies to better understand the evolutionary significance of Tp variation influenced by Wolbachia in natural Drosophila populations.
