“…Numerous studies have shown that BTs have a genetic basis and are heritable [22]; indeed, BTs appear to be more highly heritable than behavior per se [12]. BT can have important fitness consequences [14,15,[23][24][25]. Male BT can thus serve as a reliable signal of his and his offspring's genetic quality, and females should prefer males with those beneficial BTs [3].…”

Consistent individual differences in behavior [i.e., behavioral types (BTs)], are common across the animal kingdom. Consistency can make behavior an adaptive trait for mate choice decisions. Here, we present a conceptual framework to explain how and why females might evaluate a male's BT before mating. Because BTs are consistent across time or context, a male's BT can be a reliable indicator of his potential to provide direct benefits. Heritable BTs can enable informed mate choice via indirect benefits. Many key issues regarding patterns of mate choice, including sensory biases, context dependence, and assortative mating apply to BT-dependent mate choice. Understanding the relationship between BTs and mate choice may offer insights into patterns of variation and consistency common in behavioral traits. BTs and Mate ChoiceMate choice is often a key factor influencing the evolution of traits [1,2]. While sexual selection via mate choice likely has a special role as a major explanation for highly elaborated ornaments, it is not only important for explaining exaggerated, sex-specific traits. A new insight is that the choosy sex (typically females) may also select a mate based on their own and their potential mate's behavioral type (BT) (see Glossary); for example, boldness, aggressiveness, exploratory tendency, or sociability [3]. An individual is said to have a BT if its behavior is consistent across time or contexts (e.g., an individual that is more aggressive than another in a foraging context, also tends to be more aggressive in the future and/or more aggressive in a mating context) [4]. If males have consistent BTs, then male behavior observed by a female at one time and context (e.g., during courtship) provides information about his likely behavior in the past and future (e.g., during parental care). Importantly, the time scale of this correlation is not part of the definition for either human or animal personalities [4,5]. More persistent BTs (e.g., over a lifetime) presumably have greater potential to be impactful, particularly for species with long-term mating associations, but even short-term consistency (e.g., from courtship to nesting or parental behavior a few weeks later) can be important [6][7][8].With regard to mechanisms of adaptive mate choice, correlations between a potential mate's past, present, and future behaviors may determine the quality and quantity of expected direct benefits that he can provide (e.g., nuptial gifts, territory, or parental care) [3]. Within a breeding season, BTs allow a female to predict a male's future behavior towards her and her offspring, which may be particularly important for species that have paternal care, including territory defense and provisioning [9,10]. While consistency to the next breeding season is not necessarily important for all species, species that engage in long-term pair bonds may rely more heavily on BTs to determine long-term compatibility [11]. Furthermore, given that BTs are heritable (about half of BT variation is attributable to additive geneti...

“…Because of this, phenotypically different individuals can experience increased risk of predation relative to their group mates (the oddity effect; Theodorakis, 1989 ). As individual behavior and group composition are important aspects of predator avoidance ( Farine et al, 2015 ; Blake et al, 2018 ), this suggests that not only should groups differ in their anti-predator success across environments as performance curves converge and diverge, but that individuals may prefer different groups as environments change. Different individuals are affected by the oddity effect to different extents ( Rodgers et al, 2015 ).…”

The Potential for Physiological Performance Curves to Shape Environmental Effects on Social Behavior

As individual animals are exposed to varying environmental conditions, phenotypic plasticity will occur in a vast array of physiological traits. For example, shifts in factors such as temperature and oxygen availability can affect the energy demand, cardiovascular system, and neuromuscular function of animals that in turn impact individual behavior. Here, we argue that nonlinear changes in the physiological traits and performance of animals across environmental gradients—known as physiological performance curves—may have wide-ranging effects on the behavior of individual social group members and the functioning of animal social groups as a whole. Previous work has demonstrated how variation between individuals can have profound implications for socially living animals, as well as how environmental conditions affect social behavior. However, the importance of variation between individuals in how they respond to changing environmental conditions has so far been largely overlooked in the context of animal social behavior. First, we consider the broad effects that individual variation in performance curves may have on the behavior of socially living animals, including: (1) changes in the rank order of performance capacity among group mates across environments; (2) environment-dependent changes in the amount of among- and within-individual variation, and (3) differences among group members in terms of the environmental optima, the critical environmental limits, and the peak capacity and breadth of performance. We then consider the ecological implications of these effects for a range of socially mediated phenomena, including within-group conflict, within- and among group assortment, collective movement, social foraging, predator-prey interactions and disease and parasite transfer. We end by outlining the type of empirical work required to test the implications for physiological performance curves in social behavior.

For example, shifts in factors such as temperature and oxygen availability can affect the energy demand, cardiovascular system, and neuromuscular function of animals that in turn impact individual behaviour.
