Abstract: Understanding climate change in the Middle East (ME) is crucial because people’s living environment depends on rain-fed crop systems. It remains unclear if the ME climate would be affected by the Saharan vegetation collapse at the end of the mid-Holocene (MH). Proxy data suggest a transition from humid to more arid ME conditions during the period of 6.5-5 kyr BP. Using a set of idealized sensitivity experiments with an Earth System model (EC-Earth), we infer that the shift of Saharan vegetation plays a role in… Show more

“…The higher level of allele sharing between ancient samples from IRN and Levant in the Chalcolithic time period coincides with known transitions to more arid conditions in the Middle East during the period of 6.5-5 kyr BP (Sun et al 2021). It also agrees with the high genetic continuity and reduced genetic differentiation of farmers from southern Levant (Israel and Jordan) and Zagros Mountains (Iran) (Harney et al 2018, Lazaridis et al 2016.…”

“…Thus, we propose extensive gene flow from Levant lineages into SWA populations after domestication time, dating between ˜7,000 and 5,000 YBP, which suggested a North-Eastern path of gene flow from Levant into eastern parts of the Fertile Crescent. Given that the timing of this gene flow concurrences with a wet-to-dry transition in western parts of IRN regions such as Lakes Zeribar and Mirabad (Sun et al 2021), we hypothesize that changing precipitation patterns and temperature have favored the introgression of adaptive introgression genes from the Levant genetic resource into the SWA region. The same climate transition is proposed to have driven the migration of heat-resistant indicine cattle to SWA after 4,200 BP (Verdugo et al 2019).…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.
