“…Alternatively, decreased ranging and smaller energy budgets may be part of a risk-averse strategy focused on low-variance foods, while increased ranging and larger energy budgets are part of a risk-prone strategy of focusing on highvariance foods (40,41). In linking expansion and contraction of the energy budget to daily movement distance, our model suggests that constraints on ranging, such as predation (4), endurance (8), or thermoregulation (32) may also constrain the energy budget.…”

“…While ecological constraints cannot always be linked to foraging behavior (7) and physiological constraints may limit ranging ability (8), large interspecific comparisons of foraging behavior indicate that daily movement distance, D, is primarily determined by the need to acquire sufficient food energy (2,3,6). For example, daily movement distance increases with body size and diet quality, reflecting both size-related increases energy requirements and the relative scarcity of high-quality, energy-dense foods on the landscape (2,6).…”

“…1B), but changes (or stasis) in B:C do not dictate changes in the energy budget in our model, provided B Ͼ C. Instead, our model predicts expansion of ranging and the energy budget when increased ranging is profitable (e.g., food does not become depleted), and contraction when large energy budgets are a liability, perhaps in seasonal or stochastic environments prone to periods of extreme food shortage. In addition, factors unrelated to food availability, such as time constraints (31), limits to endurance (8), thermoregulatory constraints (32), or predation pressures (4), may limit ranging and consequently constrain the daily energy budget.…”

Most animals must travel to find food, incurring an unavoidable energy and time cost. Economic theory predicts, and experimental work confirms, that within species, increasing the distance traveled each day to find food has negative fitness consequences, decreasing the amount of energy invested in maintenance, repair, and reproduction. Here, we show that this relationship between daily distance traveled and reproductive success is fundamentally different between species and over evolutionary time in many lineages. Phylogenetically controlled analyses of 161 eutherian mammals indicate that, after controlling for body mass, evolutionary increases in the daily distance traveled are associated with corresponding increases in both total fertility (number of offspring per lifetime) and total offspring mass (grams of offspring per lifetime). This suggests that over evolutionary time, increasing travel distance is often part of a strategy for procuring more food energy and not necessarily a response to decreased food availability. These results have important implications for ecological comparisons among species, including assessments of habitat quality based on locomotor behavior.ecology ͉ energetics ͉ reproduction ͉ life history ͉ foraging economics H ow far will an animal travel each day? A broad range of ecological pressures influence ranging decisions (1-7), making this seemingly straightforward question exceedingly difficult to answer definitively. In the simplest case, in which an animal requiring a net energy intake of E net (J/day) acquires food energy at a constant rate B (J/m) and spends energy on travel at some rate C (J/m), it must travel sufficient distance, D (m/day), so thatPerhaps surprisingly, despite considerable variation and complexity in foraging and ranging behaviors, this simple relationship between daily movement distance, food availability, and energy requirements is generally supported by behavioral observation in a broad range of species. While ecological constraints cannot always be linked to foraging behavior (7) and physiological constraints may limit ranging ability (8), large interspecific comparisons of foraging behavior indicate that daily movement distance, D, is primarily determined by the need to acquire sufficient food energy (2, 3, 6). For example, daily movement distance increases with body size and diet quality, reflecting both size-related increases energy requirements and the relative scarcity of high-quality, energy-dense foods on the landscape (2, 6). Further, decreases in an individual's rate of food acquisition, B, whether through experimental manipulation in the laboratory (9-14), increased foraging group size (1, 4, 6, 15) or through seasonal changes in food availability in the wild (16-19) typically leads to increases in the daily distance traveled.In principle, one might expect longer daily movement distances to be energetically beneficial, since greater D will lead to greater E net as long as B Ͼ C (10, 20). In practice, however, while some species may increase foragi...

“…Studies show that the amount of time a constant speed can be sustained (i.e. presumably within the moderate domain of intensity) is predictive of (a) the amount of time an animal spends moving in open-field conditions and the distance covered (Garland, 1999), and (b) social dominance (Robson & Miles, 2000;Sinervo, Miles, Frankino, Klukowski, & De Nardo, 2000). Access to large territories in conjunction with a dominant social status eventually can lead to increased encounters with potential mates and greater reproductive success.…”

A model for systematic changes in patterns of inter-individual variation in affective responses to physical activity of varying intensities is presented, as a conceptual alternative to the search for a global dose -response curve. It is theorized that trends towards universality will emerge in response to activities that are either generally adaptive, such as moderate walking, or generally maladaptive, such as strenuous running that requires anaerobic metabolism and precludes the maintenance of a physiological steady state. At the former intensity the dominant response will be pleasure, whereas at the latter intensity the dominant response will be displeasure. In contrast, affective responses will be highly variable, involving pleasure or displeasure, when the intensity of physical activity approximates the transition from aerobic to anaerobic metabolism, since activity performed at this intensity entails a trade-off between benefits and risks. Preliminary evidence in support of this model is presented, based on a reanalysis of data from a series of studies.

“…Reilly, 2013;) because many ecologically relevant activities, such as escaping from predators, foraging and searching for reproductive partners, depend on locomotion (Meylan and Clobert, 2004;Husak et al, 2006). Therefore, locomotor performance has been widely regarded as probably associated with fitness (Christian and Tracy, 1981;Garland, 1999). …”
