“…In our example, iGP 1 and iGP 2 have equal allelic variation as I 1 GRM5[A] = I 2 GRM5[A]. This genotype determines animals to have low concentrations of blood cortisol that makes them to display low walking speed and travel relatively short distances (39,98,99). For this example, we establish that GRM5[A] animals prefer grazing in flat terrains.…”

While grazing lands can offer a diverse range of forages, individuals within herds prefer to graze some habitats and not others. They can have consistent differences in grazing patterns and occupy specific spatial domains, whilst developing tactics and strategies for foraging that are specific to their grazing personalities. In this review, we explore the development of our understanding of grazing personalities, as we move away from the search for an "optimal animal" toward designing behavior-customized herds with an arrangement of individual grazing personalities that enhance ecosystem services and productivity. We present a "grazing personality model" that accounts for the personality of individual animals and for collective behaviors of herds. We argue that grazing personalities of grazing ruminants and other large herbivores are in part genetically determined, and that they can act at the individual and collective level. The social and biophysical environments as well as the emotional state of animals regulate the expression of "grazing genes" that are observed phenotypically as distinct grazing personalities. The reproductive and sexual successes of individuals and herds filter for allele variants of grazing genes and in turn determines their relative frequency. While the selection of one grazing personality may be adequate for homogeneous pastoral systems, the design of herds with a range of grazing personalities that are matched to the habitat diversity may be a better approach to improving the distribution of grazing animals, enhancing ecosystem services, and maximizing productivity.

“…There are some indications that early-life stress may increase the correlations between and within traits (i.e. repeatability) (Briffa, 2013;Burton, Killen, Armstrong, & Metcalfe, 2011;Guenther, Groothuis, Krüger, & Goerlich-Jansson, 2018;Han & Dingemanse, 2017;Jenkins, 2011;Merrill & Grindstaff, 2018;Royauté, Greenlee, Baldwin, & Dochtermann, 2015).

“…Across vertebrate taxa, there is strong evidence that glucocorticoid hormones mediate environmental stressors through pleiotropic effects on multiple neurological, physiological and behavioural traits (reviewed in Hau, Casagrande, Ouyang, & Baugh, 2016). Experimental work indicates potential for glucocorticoids to alter associations between life history, physiological and behavioural traits (Guenther et al, 2018;Merrill & Grindstaff, 2018). Glucocorticoids may be particularly meaningful in responding to changes in energy demands as they help adjust energy balance according to current needs by coordinating responses to regular but also to acute, unpredictable circumstances (Sapolsky, Romero, & Munck, 2000;Wingfield, 2013).…”

Environmental effects on the covariation among pace‐of‐life traits

et al. 2020

Pace-of-life syndromes (POLSs) are suites of life-history, physiological and behavioral traits that arise due to trade-offs between allocation to current and future reproduction. Traits generally show covariation that can arise from genetic and environmental influences on phenotypes and constrain the independent evolution of traits, resulting in fitness consequences and impacts on population dynamics. The notion that correlations among traits may vary among populations along environmental gradients suggests an important role for the environment in shaping and maintaining POLS. However, no synthesis has been attempted of the myriad ways in which environmental factors should influence POLS. Here, we formulate a series of hypotheses targeting the critical interfaces of the environment and life history-behaviour associations across different organisms. We discuss the hypotheses in light of findings from a systematic review of studies that measured changes in the association between behavior and life-history traits as a function of environmental conditions. The review revealed that POLS is often shaped by environmental variation, where harshness of the environment in early life has the most consistent effects on POLS. However, only partial or no effects of environmental variation were found in a number of studies, which may result from the highly variable study systems, traits, and environments studied. We highlight promising directions arising from the available studies and identify knowledge gaps that, if unaddressed, will impede progress in the field.

A range of life-history strategies along a slow-fast continuum emerge due to trade-offs between allocation to current and future reproduction. Pace-of-life syndromes (POLS) are suites of correlated life-history, physiological and behavioral traits that arise due to these trade-offs. The notion that correlations among traits may vary between populations of the same species or along environmental gradients suggests an important role for the environment in shaping and maintaining POLS. Understanding how environmental conditions influence POLS is important for understanding evolutionary change as covariation between traits may constrain their independent evolution. Here, we formulate a series of hypotheses on how environmental conditions influence POLS, with specific focus on the integration of behavior with life-history traits. We make predictions on the interactions among defining features of the environment (harshness, predictability) and type of organism (taxonomy, endothermy, life stage). We review the empirical support for each hypothesis from studies that measured changes in the association between behavior and life-history traits as a function of environmental conditions. Environmental factors were frequently found to influence the covariance of behavioral traits with life history but the effects were not broadly generalizable across study systems. Evidence of environmental harshness and the significance of early life environment suggest these as important determinants of POLS, but environmental predictability and differences between taxa are, in essence, unstudied. We identify knowledge gaps and highlight promising directions arising from current studies.
