Abstract
Abstract
Patterns in eco-physiological traits of pangolins and carnivorans are studied, which are functions of underlying Dynamic Energy Budget parameters. The data, parameter values and traits are accessible in the open access Add-my-Pet collection, which currently contains 7 out of 8 species of pangolins and 131 of the extant 276 species of carnivorans and 653 of the extant 6400 species of mammals. Paucity of data and species not included reflect the actual state of knowledge: many species are endangered and/or little measured data is readily available. Although musteloids and pinnipeds form the clade Mustelida, they appear at opposite ends of the classical multidimensional scaling diagram, using 14 traits on all mammals. Yet, in general, the energetic parameters bear a strong taxonomic signal. The weight at birth is proportional to ultimate weight: small for carnivorans and pangolins; extra small for bears; and much larger, but typical for mammals, for the pinnipeds and sea otters. How respiration scales with size is taxon-specific, and we discuss how the body-size scaling of reserve capacity interferes with the waste-to-hurry pattern. Despite their high allocation to soma, the life time cumulated mass of neonates of pangolins and carnivorans equals their own ultimate weight; pinnipeds allocate more to maturation and reproduction. Applying models to support conservation efforts entails needing realistic parameter values. This study contributes to the emerging field of assessing the realism of parameters in biological and evolutionary context.
