“…This mechanism for transgenerational phenotypic plasticity, or maternal effect, is defined as the ability of a female to alter its offspring's phenotype, allowing it to survive in a specific environment (Bernardo 1996;Mousseau and Fox 1998;Fox et al 1999;Freinschlag and Schausberger 2016). In phytoseiid mites, maternal strategies promoting offspring survival have been associated with food deprivation, risk of intraguild predation, and risk of sibling cannibalism (Toyoshima and Amano 1998;Schausberger and Hoffmann 2008;Schausberger 2011, 2015;Seiter and Schausberger 2015). To our knowledge, only one published study has reported a maternal effect associated with relative humidity in mites: in larvae of the American dog tick Dermacentor variabilis (Say) (Acari: Ixodidae), the ability to absorb water vapor from the air is under maternal control (Yoder et al 2006).…”

The ability of an organism to adapt to short-term environmental changes within its lifetime is of fundamental importance. This adaptation may occur through phenotypic plasticity. Insects and mites, in particular, are sensitive to changes in temperature and humidity, especially during the juvenile stages. We studied the role of phenotypic plasticity in the adaptation of eggs to different relative humidity conditions, in the predatory mite Phytoseiulus persimilis, used worldwide as a biological control agent of the spider mite Tetranychus urticae. The biocontrol efficacy of P. persimilis decreases under dry conditions, partly because P. persimilis eggs are sensitive to drought. We exposed P. persimilis adult females from two different strains to constant and variable humidity regimes and evaluated the hatching rate of their eggs in dry conditions, as well as the survival and oviposition rates of these females. Whereas the eggs laid by P. persimilis females exposed to constant high humidity did not survive in dry conditions, females exposed to constant low humidity started laying drought-resistant eggs after 24 h of exposure. Survival and oviposition rates of the females were affected by humidity: females laid fewer eggs under constant low humidity and had a shorter lifespan under constant high and constant low humidity. The humidity regimes tested had similar effects across the two P. persimilis strains. Our results demonstrate that transgenerational phenotypic plasticity, called maternal effect, allows P. persimilis females to prepare their offspring for dry conditions.

“…Learning and memory are thought to be hereditarily transmitted from parents to their filials. In addition to the transmissions of parent's cognitive behaviors directly to their filials, such as specific odor-induced fear memory [ 3 ] and anti-predation behavior [ 4 ], the ability of learning and memory may be transmitted from parents to their filials. Genetics and epigenetic regulation are thought to be molecular bases for the transgenerational inheritance of learning ability and memory to specific events [ 9 – 17 ].…”

“…There are two forms of transgenerational intelligence, the transmission of parent's cognitions and behaviors directly to their filials, such as specific odor-induced fear memory [ 3 ] and anti-predation behavior [ 4 ], as well as the transmission in the ability of learning and memory to their filials [ 5 – 8 ]. The transmission of specific memory from parents to their filials cannot rule out the maternal effects on filials, such as social learning [ 49 , 50 ] after filials are born.…”

The capabilities of learning and memory in parents are presumably transmitted to their offsprings, in which genetic codes and epigenetic regulations are thought as molecular bases. As neural plasticity occurs during memory formation as cellular mechanism, we aim to examine the correlation of activity strengths at cortical glutamatergic and GABAergic neurons to the transgenerational inheritance of learning ability. In a mouse model of associative learning, paired whisker and odor stimulations led to odorant-induced whisker motion, whose onset appeared fast (high learning efficiency, HLE) or slow (low learning efficiency, LLE). HLE male and female mice, HLE female and LLE male mice as well as HLE male and LLE female mice were cross-mated to have their first generation of offsprings, filials (F1). The onset of odorant-induced whisker motion appeared a sequence of high-to-low efficiency in three groups of F1 mice that were from HLE male and female mice, HLE female and LLE male mice as well as HLE male and LLE female mice. Activities related to glutamatergic neurons in barrel cortices appeared a sequence of high-to-low strength in these F1 mice from HLE male and female mice, HLE female and LLE male mice as well as HLE male and LLE female mice. Activities related to GABAergic neurons in barrel cortices appeared a sequence of low-to-high strength in these F1 mice from HLE male and female mice, HLE female and LLE male mice as well as HLE male and LLE female mice. Neuronal activity strength was linearly correlated to learning efficiency among three groups. Thus, the coordinated activities at glutamatergic and GABAergic neurons may constitute the cellular basis for the transgenerational inheritance of learning ability.

“…These hypotheses suggest that during development, individuals are physiologically (and thus behaviourally) "tuned" to respond to salient environmental cues in a way that maximises fitness in later life (19,83,107,108).The adaptive significance of this programming may only become evident under certain contexts in later life, such as when later environments match this experienced in development (109,110). For example, in mites pre-natal exposure to the risk of predation produces offspring that are less active when living in high predation areas (111). This result provides evidence for a possible adaptive response, in that it allows parents to communicate cues about the likely state of the post-natal environment (i.e.…”

Developmental stress and social phenotypes: integrating neuroendocrine, behavioural and evolutionary perspectives

SummaryThe social world is filled with different types of interactions, and social experience interacts with stress on several different levels. Activation of the neuroendocrine axis that regulates the response to stress can have consequences for innumerable behavioural responses, including social decision making and aspects of sociality such as gregariousness and aggression. This is especially true for stress experienced during early life, when physiological systems are developing and highly sensitive to perturbation. Stress at this time can have persistent effects on social behaviours into adulthood. One important question remaining is to what extent these effects are adaptive. This paper initially reviews the current literature investigating the complex relationships between the hypothalamic-pituitaryadrenal (HPA) axis and other neuroendocrine systems and several aspects of social behaviour in vertebrates. In addition the review explores the evidence surrounding the potential for 'social programming' via differential development and activation of the HPA axis, providing an insight into the potential for positive effects on fitness following early life stress. Finally the paper provides a framework from which novel investigations could work to fully understand the adaptive significance of early life effects on social behaviours. BackgroundThe ability to effectively interact with conspecifics is a vital skill, which we have only just begun to explore in terms of its impact on fitness (1, 2). In humans, this ability is also highly valued and disorders known to reduce our ability *Author for correspondence (Karen.spencer@st-andrews.ac.uk). †Present address: School of Psychology & Neuroscience, University of St Andrews, South Street, St Andrews, KY16 9JP to interact or understand the emotional cues of others place sufferers at significant disadvantages, with long term impacts on health and wellbeing. Understanding the factors that give rise to individual differences in 'social competence' is therefore of fundamental importance to both our knowledge of human pathologies, but also animal welfare and population structure. Stress is a major regulator of social behaviour and in turn social influences can alter behavioural and physiological responses to stress (3-5). Activation of the vertebrate neuroendocrine axis which regulates the response to stress can cause pleiotropic effects on several aspects of social behaviour, including reduced social interaction, increased affiliative behaviours, increased aggression and altered mating behaviours (6-15). The direction and magnitude of these effects is often related to the context within which the experiment was conducted as well as the type of stressor that was experienced and the life history strategy of the species in question, however there is clear evidence to suggest that stress during all life stages can impact on sociality.One major driver of social ability in adulthood is the conditions experienced during development, when neural substrates and physiological systems...
