“…Evolution of TGP depends on how accurately the parental cue eliciting TGP predicts the environment that will exert selection on the offspring phenotype (Auge et al, 2017;Bell and Hellmann, 2019;Donelan et al, 2020). Cue accuracy depends on the time lag between cue perception and expression of offspring phenotypes ( §3.2).…”

“…Cue accuracy depends on the time lag between cue perception and expression of offspring phenotypes ( §3.2). Therefore, two developmental aspects may influence the presence, strength and direction of predator-induced TGP: (1) the life-history stage at which parents perceive environmental cues (induction time), and (2) the life-history stage at which the offspring initiate responses (expression time) (Figure 2; Burton and Metcalfe, 2014;Donelson et al, 2018;Bell and Hellmann, 2019;Yin et al, 2019;Donelan et al, 2020). Among the 55 studies that explore transgenerational effects in response to predation risk, 18 investigate patterns of TGP with different timings of exposure in parents (four studies) or expression in offspring (14 studies).…”

“…The time at which an environmental change is experienced can directly influence phenotypic responses in both the exposed individual (WGP) and its offspring (TGP) (Burton and Metcalfe, 2014;Donelson et al, 2018;Donelan et al, 2020). Some theoretical models predict that early-perceived cues in parental development should have weaker effects on offspring than lateperceived cues (Ezard et al, 2014;Prizak et al, 2014).…”

“…Indeed, later parental environments are better predictors of offspring environment because of the shorter time lag between perception of cues and the predicted environment. Therefore, the period before and during reproduction in parental development is expected to be a critical period for TGP induction (Donelan et al, 2020). In contrast, some empirical studies rather identify the early parental development (i.e., embryonic or neonate phases) as particularly sensitive to influence TGP (Burton and Metcalfe, 2014;Fawcett and Frankenhuis, 2015;Donelson et al, 2018;Yin et al, 2019), which might be linked to a higher proportion of early embryonic cells that are highly sensitive to environmental cues (Burton and Metcalfe, 2014).…”

“…We define TGP as all phenotypic changes in a new generation that are triggered by the environment experienced by the previous generation(s). This broad definition (also used in very recent reviews: Bell and Hellmann, 2019;Yin et al, 2019;Donelan et al, 2020) allows to encompass effects on offspring phenotype due to the effect of predator exposure on maternal or paternal conditions (state-based TGP) and due to signals transmitted by parents (adaptive TGP). To search for relevant studies, we used the following keywords in the Web Of Science Core collection: ("trans?generational plasticity" OR "trans?generational effect?"…”

Transgenerational Plasticity in the Context of Predator-Prey Interactions

Almost all animal species are engaged in predator-prey interactions. These interactions, variable in time and space, favor the emergence and evolution of phenotypic plasticity, which allows prey to fine-tune their phenotype to the current risk of predation. A famous example is the induction of defensive neck-teeth, spines or helmets in some water fleas when they detect cues of predator presence. In general, the response may involve different types of traits (behavioral, morphological, physiological, and life-history traits), alone or in combination. The induced traits may be adaptive anti-predator defenses or reflect more general stress-based responses. Recently, it has been found that predator-induced plasticity occurs not only within but also across generations (transgenerational plasticity), i.e., the phenotype of a generation is influenced by the detection of predator-cues in previous generation(s), even if the current generation is not itself exposed to these cues. In this paper, we aim to review this accumulating literature and propose a current state of key aspects of predator-induced transgenerational plasticity in metazoans. In particular, we review whether patterns of predator-induced transgenerational plasticity depend on the type of traits. We analyze the adaptive value of predator-induced transgenerational plasticity and explore the evidence for its evolution and underlying mechanisms. We also consider its temporal dynamics: what are the time windows during which predator-cues must be detected to be transmitted across generations? Are transgenerational responses in offspring stage-dependent? How many generations does transgenerational plasticity persist? Finally, we discuss other factors highlighted in the literature that influence predator-induced transgenerational plasticity: what are the relative contributions of maternal and paternal exposure to predator-cues in generating transgenerational plasticity? Do transgenerational responses depend on offspring sex? Do they scale with the perceived level of predation risk? This review shows that we are only at the beginning of understanding the processes of predatorinduced transgenerational plasticity, and it encourages future research to fill the lack of knowledge highlighted here.

Objectives To investigate whether the Cayo Santiago, Puerto Rico (Latitude: 18.1564°N; temperature range 19°C to 32°C) rhesus macaque population has acclimated to their tropical island conditions since arriving from Lucknow, India (Latitude: 26.8470°N; temperature range 8°C to 41°C) in 1938. Materials and Methods Using the derived skeletal collection, measurements were taken of long bone lengths, diaphyseal circumference, and body weight using 635 (237 males and 398 females) skeletally mature individuals. Measurements sampled colony members born over a 51‐year time span at Cayo Santiago, from 1951 to 2002. Results Results demonstrated that body weights and diaphyseal circumferences significantly declined in both males and females. Long bone lengths relative to body weight and diaphyseal circumference also increased in females. Whereas body weight, long bone length and diaphyseal circumference declined at near parallel rates in males. Discussion The population has acclimated to homogenous, tropical, conditions of the Caribbean island since their arrival over 80 years ago. Trends in both sexes aligned with Bergmann's rule, though females displayed a greater decline in body weight, as well as greater affinity with Allen's rule, than did males. Buffering effects related to male competition may be responsible for this discrepancy. Overall, the Cayo Santiago populations, as shown over a significant period (1951–2002) of their history, have acclimated to their island conditions by decreasing in size and altering body proportions.
