The Evolution Of Locomotion Across Land-Water Transitions In Crocodylomorpha

Obiettivo

CROCOLOCOEVO will test the hypothesis that habitat transitions in Crocodylomorpha (crocodiles and their extinct relatives) involved trade-offs (anatomy, function, behaviour and performance) between terrestrial and aquatic locomotor abilities. Analyses will span from biomechanical modelling and simulation as well as in vivo and ex vivo experimentation, and biorobotic analyses of swimming, to characterise links across the anatomy-function-performance spectrum in contexts of locomotor behaviour and habitats. The results first will be conceptually unified by relating 3D skeletal morphology to function (e.g. joint ranges of motion). Next, CROCOLOCOEVO will mechanistically test (for 14 representative taxa across the phylogeny and morphological diversity of Crocodylomorpha) the links of form and function to biomechanical locomotor performance via predictive dynamic simulations and biorobotic analyses of swimming hydrodynamic performance, which will be placed into functional adaptive landscapes to reconstruct how form, function and performance evolved across Crocodylomorpha and what trade-offs existed for different habitats. Field studies of extant Freshwater Crocodiles will identify why, when, how and why different locomotor abilities are used (and how often) in captive and then wild individuals, to place locomotion into an ecological context for this representative species. CROCOLOCOEVO will finish by synthesizing its findings for locomotion in a broader context using character mapping of quantitative and qualitative traits; including locomotor form and function as well as non-locomotor traits such as feeding, sensory and ventilatory innovation; mapped across crocodylomorph phylogeny to test my main hypothesis and compare the findings to patterns for other character complexes (e.g. feeding), revealing how habitats did or did not result in convergent evolution across Crocodylomorpha.
