Vertical transhumance is an important animal husbandry strategy that provides livestock with consistent access to pasture throughout the year and contributed to the intensification of sheep and goat husbandry in the Near East over 10,000 years ago. Sequential carbon (delta C-13) and oxygen (delta O-18) isotope analyses of teeth from domesticated sheep and goats dating to the early Neolithic (9200 to 8700 cal yr B.P.) from a region of strong local topographic relief in southern Jordan exhibit inverse cyclical isotopic variation characterized by the coincidence of high delta O-18 values with low delta C-13 values indicating ingestion of C-13-depleted plants during the summer season. This pattern is consistent with vertical transhumance of caprines moving from low-elevation C-3/C-4 lrano-Turanian pastures to higher-elevation Mediterranean C-3 pastures during the summer, but other seasonally directed animal husbandry strategies involving amendment of livestock diets generate a similar isotopic outcome. Caprine delta O-18 values referenced against the oxygen isotope ratios of contemporaneous obligate drinking cattle and non obligate drinking mountain gazelle, bovids with limited home ranges, help distinguish the influence of meteoric water, delta O-18-enriched leaf water, and movement on the oxygen isotopic composition of sheep and goat tooth enamel. This approach assists in independent validation of vertical transhumance hypothesized for inverse cyclical variation in sequential delta C-13 and delta O-18 values and, also, decouples seasonal foddering from mobility in the carbon isotopic dietary record. The isotopic data presented here reveal that complex sheep and goat husbandry systems involving vertical transhumance, stationary flock-keeping, and winter foddering were in place by the late tenth millennium cal y.r. B.P. east of the Jordan Valley. (C) 2017 Published by Elsevier B.V.
