Data from: Diversification of the ruminant skull along an evolutionary line of least resistance
<p>Clarifying how microevolutionary processes scale to macroevolutionary patterns is a fundamental goal in evolutionary biology, but these analyses, requiring comparative datasets of population-level variation, are limited. By analyzing a previously published dataset of 2859 ruminant crania, we find that variation within and between ruminant species is biased by a highly conserved mammalian-wide allometric pattern, CREA (CR-aniofacial E-volutionary A-llometry), where larger species have proportionally longer faces. Species with higher morphological integration and species more biased towards CREA have diverged farther from their ancestors, and Ruminantia as a clade diversified farther than expected in the direction of CREA. Our analyses indicate that CREA acts as an evolutionary 'line of least resistance' and facilitates morphological diversification due to its alignment with the browser-grazer continuum. Taken together, our results demonstrate that constraints at the population-level can produce highly directional patterns of phenotypic evolution at the macroevolutionary scale. Further research is needed to explore how CREA has been exploited in other mammalian clades.</p>

Data for: Environmental conditions alter behavioural organization and rhythmicity of a large Arctic ruminant across the annual cycle
<p><span>The existence and persistence of rhythmicity in animal activity during phases of environmental change is of interest in ecology and chronobiology. A wide diversity of biological rhythms in response to</span> <span>exogenous </span>conditions and internal stimuli have been uncovered, especially for polar vertebrates. However, empirical data supporting circadian organization of large ruminating herbivores remains inconclusive. <span>Using year-round tracking data of the largest Arctic ruminant, the muskox (</span><i>Ovibos moschatus</i><span>), we modelled rhythmicity as a function of behaviour and environmental conditions. Behavioural states were classified based on patterns in hourly movements, and incorporated within a periodicity analyses framework. We found that ultradian rhythmicity was prevalent when muskoxen were foraging and resting in mid-winter (continuous darkness). However, the probability of rhythmicity declined with increasing photoperiod until largely disrupted in mid-summer (continuous light). Individuals that remained rhythmic during mid-summer foraged in areas with lower plant productivity (NDVI) than arrhythmic individuals. We conclude that muskoxen may use internal time keeping when forage resources are low, but that the importance of this mechanism weakens once environmental conditions allow energetic reserves to be replenished. We argue that alimentary function and metabolic requirements are critical determinants of biological rhythmicity in muskoxen, which likely applies to ruminating herbivores in general. </span></p>
