“…Bone data are likely to reflect isotope fractionations of both the trophic effect and the bone‐forming process as observed for Ca (Appendix S2: Figure S1). The lower δ 44/40 Ca values in bones relative to muscles (0.32 ± 0.06‰) agree with the reported offset in Ca stable isotopic composition between soft tissue and mineralized tissue (Dodat et al, 2021; Skulan & DePaolo, 1999; Tacail et al, 2014, 2020). Consequently, it is reasonable to assume that a slight 88 Sr fractionation also exists between bone apatite and blood.…”

“…These studies found a significant decrease in δ 44/40 Ca values in mineralized tissues, such as bone and tooth enamel, compared to dietary sources with increasing trophic level. For vertebrates, it is assumed that this 44 Ca depletion along the trophic chain is mainly driven by isotopic fractionation during bone mineralization from the blood and by kidney regulation of the Ca cycle (Channon et al, 2015;Dodat et al, 2021;Hassler et al, 2021;Heuser et al, 2016;Reynard et al, 2010;Skulan et al, 2007;Skulan & DePaolo, 1999;Tacail et al, 2014Tacail et al, , 2020. Furthermore, direct uptake of Ca from the water through gills could buffer the diet-bone Ca isotopic fractionation as suggested for marine teleost and elasmobranch fish species (Clementz et al, 2003;Martin et al, 2015;Tacail et al, 2020).…”

Calcium and strontium stable isotopes reveal similar behaviors of essential Ca and nonessential Sr in stream food webs

Recent studies showed the potential of stable isotopes of the macronutrient calcium (δ 44/40 Ca) and nonessential strontium (δ 88/86 Sr) as new trophic level indicators in terrestrial vertebrates and marine teleost fishes. In this study, we tested whether similar Ca and Sr isotopic fractionation trends existed in macroinvertebrate-dominated stream food webs compared to vertebrates despite their physiological differences. We have determined the δ 44/40 Ca and δ 88/86 Sr values as well as the 87 Sr/ 86 Sr ratios of stream macroinvertebrates and small gobies and their potential metal sources (stream water, periphyton, and terrestrial plant litter) in upper and lower reaches of two streams in the Lake Biwa catchment, central Japan. The 87 Sr/ 86 Sr ratios revealed that stonefly nymphs, crustacea, and gobies mostly relied on aquatic Sr sources. Higher 87 Sr/ 86 Sr ratios of some crane fly and caddisfly larvae, mayfly, dobsonfly, and dragonfly nymphs indicated greater terrestrial contributions via plant litter.Positive correlations between the δ 44/40 Ca and δ 88/86 Sr values implied that similar Ca and Sr sources existed, and that Ca and Sr stable isotopes underwent similar fractionation trends although Sr was not essential. The δ 44/40 Ca and partly the δ 88/86 Sr values were positively correlated with Sr/Ca ratios and negatively with δ 15 N values indicating trophic effects on Ca and Sr stable isotopes.The enrichment of 44 Ca and 88 Sr in large filter-feeding caddisfly larvae was a notable exception from these trophic trends. Our data confirm that the trophic 44 Ca and 88 Sr depletion observed for marine teleost fishes and terrestrial vertebrates also applied to macroinvertebrate-dominated stream food webs despite their different physiologies indicating that shared mechanisms of Ca and Sr isotopic fractionation may exist at the cellular or molecular level between these taxa.

“…1,4 As a result, Ca isotope systematics are being used to track a variety of processes including early solar system evolution, crust-mantle processes, paleotemperature reconstruction, and paleontological and medical processes. [5][6][7][8][9][10][11][12][13][14][15][16][17][18] Two analytical approaches have been used for Ca isotopic determination, namely double-spike using thermal ionization mass spectrometry (DS-TIMS) and standard-sample bracketing using multi-collector inductively coupled plasma-mass spectrometry (SSB-MC-ICP-MS). High-precision measurements of Ca isotopes were rst achieved in 1978, where Russell et al 19 used the double-spike ( 42 Ca- 48 Ca) technique on a TIMS to obtain the ratio between the two most abundant isotopes 40 Ca and 44 Ca, denoted as d 44/40 Ca.…”

“…Fat has a high energy value, and enables gluconeogenesis, a metabolic process occurring primarily in the liver and kidneys that produces carbohydrates from protein and fat (Speth and Spielmann, 1983;Speth, 2010). These advantages therefore go a long way to explaining why Paleolithic human groups sought to harvest fat wherever it was available, including fat contained in the marrow and cancellous tissue of very large and large mammals long bones (Costamagno and Rigaud, 2013;Smith et al, 2015;Ben-Dor et al, 2016;Blasco et al, 2019a;Boschian et al, 2019;Morin, 2020;Dodat et al, 2021). The preparation of broths based on fat contained in bone tissue observed among the Nunamiut by Binford (1978) suggests that such processes may have existed in Paleolithic societies (Speth, 2015).…”

“…Furthermore, as data are cumulative, we only have an overall picture of the diet and it is impossible to gauge the diet consumed on a daily basis. Moreover, it is difficult to discern the ratio of meat in the diet of past hominins, and especially for the Late Pliocene and Early Pleistocene periods, although some new isotopic analyses using barium, calcium or zinc isotopes seem quite relevant for this purpose (Balter et al, 2012;Jaouen et al, 2016;Martin et al, 2020;Dodat et al, 2021).…”

Despite the omnivorous diet of most human populations, meat foraging gradually increased during the Paleolithic, in parallel with the development of hunting capacities. There is evidence of regular meat consumption by extinct hominins from 2 Ma onward, with the first occurrence prior to 3 Ma in Eastern Africa. The number of sites with cut-marked animal remains and stone tools increased after 2 Ma. In addition, toolkits became increasingly complex, and various, facilitating carcass defleshing and marrow recovery, the removal of quarters of meat to avoid carnivore competition, and allowing the emergence of cooperative (i.e., social) hunting of large herbivores. How can we assess the energy costs and benefits of meat and fat acquisition and consumption for hunter-gatherers in the past, and is it possible to accurately evaluate them? Answering this question would provide a better understanding of extinct hominin land use, food resource management, foraging strategies, and cognitive abilities related to meat and fat acquisition, processing, and consumption. According to the Optimal Foraging Theory (OFT), resources may be chosen primarily on the basis of their efficiency rank in term of calories. But, could other factors, and not only calorific return, prevail in the choice of prey, such as the acquisition of non-food products, like pelts, bone tools or ornaments, or symbolic or traditional uses? Our main goal here is to question the direct application of behavioral ecology data to archeology. For this purpose, we focus on the issue of animal meat and fat consumption in human evolution. We propose a short review of available data from energetics and ethnographic records, and provide examples of several various-sized extant animals, such as elephants, reindeer, or lagomorphs, which were some of the most common preys of Paleolithic hominins.
