Results show that L. polyphemus, S. inexpectans and R. rex have broadly similar microstrain patterns, reflecting effective durophagous abilities. Conversely, low microstrain values across the O. serratus protopodite suggest that the elongate gnathobasic spines transferred minimal strain, implying that this species was less well-adapted to masticate hard prey. These results confirm that Cambrian euarthropods with transversely elongate protopodites bearing short, robust gnathobasic spines were likely durophages. Comparatively, taxa with shorter protopodites armed with long spines, such as O. serratus, were more likely restricted to a soft food diet. The prevalence of Cambrian gnathobase-bearing euarthropods and their various feeding specializations may have accelerated the development of complex trophic relationships within early animal ecosystems, especially the 'arms race' between predators and biomineralized prey.]]> Wed 14 Sep 2022 09:05:36 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:17480 Wed 11 Apr 2018 14:45:23 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38235 Tue 27 Feb 2024 14:06:16 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50407 Tue 25 Jul 2023 17:23:12 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:16804 Tue 24 Aug 2021 13:58:53 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47070 Thu 03 Aug 2023 13:40:37 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:13299 Sat 24 Mar 2018 08:18:05 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:5260 Sat 24 Mar 2018 07:46:35 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:25912 Sat 24 Mar 2018 07:27:51 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32033 Mon 23 Sep 2019 14:02:00 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45848 Mon 07 Nov 2022 14:38:08 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51913 Fri 22 Sep 2023 10:39:52 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40601 hyperkeystone or super predator species as they have shown a capacity to consume animals at rates many times higher than any other non-human species. However, the extent to which humans induce adaptive defences in animals is not as clear. Systems involving large mammals may be particularly well-suited for the study of human-induced defences given that these species have been disproportionately exploited (for food and competition) over evolutionary time by humans. To begin this process we first had to examine the context in which large mammals could adaptively evolve inducible defences in relation to human lethality. With the plausibility of these conditions satisfied, we then conducted an extensive review to document the inducible defences that have been detected in large mammals. All of the 187 studies reviewed documented the behavioural plasticity of large mammals to human lethality. No morphological adaptive defences were detected. However, the extent to which the observed behavioural plasticity of large mammals is representative of adaptive inducible defences remains unclear because the fitness trade-offs (i.e. costs), an integral condition for inducible defences to evolve, were implied rather than quantified among close to 92% of this research. We make recommendations for renewed ingenuity in the development of field experiments that can quantify these costs and discuss the implications of human lethality on the ecology, conservation and management of large mammals.
