Dataset Information

Kill site database: A unified dataset on human-megafauna interactions across time and space.

ABSTRACT: The database presented in this data article is related to the paper "Megafauna kill sites in South America: a critical review" [1]. It includes a list of 134 publications on human-megafauna interaction, with 69 archaeological sites showing human-megafauna interaction. From these sites, 44 present a minimum human-megafauna association, from which up to 17 megafauna kill sites were classified, with up to 15 exploited extinct megafauna taxa. It also provides a list of current taxonomic classifications of extinct megafauna that humans have exploited according to empirical evidence presented in the related paper. The megafauna kill sites were classified based on five restrictive criteria according to Grayson and Meltzer's (2015, 2002), Borrero's (2009) and Mothé et al.'s (2020) protocol. The kill sites database reflects the empirical evidence on megafauna exploitation by humans available in scientific literature and is useful to understand the human-megafauna interactions in the late Quaternary. Finally, we also provide our online repository (www.killsitedatabase.com), an initiative to unify the evidence on megafauna kill sites (and their related data) worldwide, starting in South America.

Project description:Several stimulus factors are important in multisensory integration, including the spatial and temporal relationships of the paired stimuli as well as their effectiveness. Changes in these factors have been shown to dramatically change the nature and magnitude of multisensory interactions. Typically, these factors are considered in isolation, although there is a growing appreciation for the fact that they are likely to be strongly interrelated. Here, we examined interactions between two of these factors - spatial location and effectiveness - in dictating performance in the localization of an audiovisual target. A psychophysical experiment was conducted in which participants reported the perceived location of visual flashes and auditory noise bursts presented alone and in combination. Stimuli were presented at four spatial locations relative to fixation (0°, 30°, 60°, 90°) and at two intensity levels (high, low). Multisensory combinations were always spatially coincident and of the matching intensity (high-high or low-low). In responding to visual stimuli alone, localization accuracy decreased and response times (RTs) increased as stimuli were presented at more eccentric locations. In responding to auditory stimuli, performance was poorest at the 30° and 60° locations. For both visual and auditory stimuli, accuracy was greater and RTs were faster for more intense stimuli. For responses to visual-auditory stimulus combinations, performance enhancements were found at locations in which the unisensory performance was lowest, results concordant with the concept of inverse effectiveness. RTs for these multisensory presentations frequently violated race-model predictions, implying integration of these inputs, and a significant location-by-intensity interaction was observed. Performance gains under multisensory conditions were larger as stimuli were positioned at more peripheral locations, and this increase was most pronounced for the low-intensity conditions. These results provide strong support that the effects of stimulus location and effectiveness on multisensory integration are interdependent, with both contributing to the overall effectiveness of the stimuli in driving the resultant multisensory response.
