Data from: The functional role of serial dependence

Guido Marco Cicchini, Kyriaki Mikellidou & David C. Burr
The world tends to be stable from moment to moment, leading to strong serial correlations in natural scenes. As similar stimuli usually require similar behavioral responses, it is highly likely that the brain has developed strategies to leverage these regularities. A good deal of recent psychophysical evidence is beginning to show that the brain is sensitive to serial correlations, causing strong drifts in observer responses towards previously seen stimuli. However, it is still not clear...

Data from: Exploring mechanisms and origins of reduced dispersal in island Komodo dragons

Loss of dispersal typifies island biotas, but the selective processes driving this phenomenon remain contentious. This is because selection via, both indirect (e.g. relaxed selection or island syndromes) and direct (e.g. natural selection or spatial sorting) processes may be involved, and no study has yet convincingly distinguished between these alternatives. Here we combined observational and experimental analyses of an island lizard, the Komodo dragon (Varanus komodoensis, the world’s largest lizard), to provide evidence for the...

Data from: Pupillometry reveals perceptual differences that are tightly linked to autistic traits in typical adults

Marco Turi, David Charles Burr & Paola Binda
The pupil is primarily regulated by prevailing light levels, but is also modulated by perceptual and attentional factors. We measured pupil-size in typical adult humans viewing a bistable-rotating cylinder, constructed so the luminance of the front surface changes with perceived direction of rotation. In some participants, pupil diameter oscillated in phase with the ambiguous perception, more dilated when the black surface was in front. Importantly, the magnitude of oscillation predicts autistic traits of participants, assessed...

Data from: Relatedness within and between leks of golden-collared manakin differ between sexes and age classes

Leonida Fusani, Julia Barske, Chiara Natali, Guido Chelazzi & Claudio Ciofi
Several hypotheses have been advanced to explain the evolution of leks, a mating system in which males aggregate at display sites where females choose their mates. Only a small proportion of males obtain copulations, and why other males join the lek remains unexplained. One hypothesis has called kin selection into play: if juvenile males join leks where their relatives display and contribute to attract females to the lek, they can gain indirect fitness benefits. We...

Data from: Response to short-term deprivation of the human adult visual cortex measured with 7T BOLD

Paola Binda, Jan W. Kurzawski, Claudia Lunghi, Laura Biagi, Michela Tosetti & Maria Concetta Morrone
Sensory deprivation during the post-natal "critical period" leads to structural reorganization of the developing visual cortex. In adulthood, the visual cortex retains some flexibility and adapts to sensory deprivation. Here we show that short-term (2h) monocular deprivation in adult humans boosts the BOLD response to the deprived eye, changing ocular dominance of V1 vertices, consistent with homeostatic plasticity. The boost is strongest in V1, present in V2, V3 &V4 but absent in V3a and hMT+....

Data from: Genetic pedigree analysis of the pilot breeding program for the rediscovered Galapagos giant tortoise from Floreana island

Joshua M. Miller, Maud C. Quinzin, Elizabeth H. Scheibe, Claudio Ciofi, Fredy Villalva, Washington Tapia & Adalgisa Caccone
An aim of many captive breeding programs is to increase population sizes for reintroduction and establishment of self-sustaining wild populations. Genetic analyses play a critical role in these programs: monitoring genetic variation, identifying the origin of individuals, and assigning parentage to track family sizes. Here we use genetic pedigree analyses to examine three seasons of a pilot breeding program for the Floreana island Galapagos giant tortoise, C. niger, that had been declared extinct for ~150...

Data from: Assessing reliance on vector navigation in the long-distance oceanic migrations of green sea turtles

Giulia Cerritelli, Giuseppe Bianco, Giacomo Santini, Annette C. Broderick, Brendan J. Godley, Graeme C. Hays, Paolo Luschi & Susanne Åkesson
Vector navigation, i.e. maintaining a constant heading for a given amount of time, is hypothesized to provide a viable basis for the navigational feats of a number of long-distance animal migrants. Since animals following this strategy are subject to drift by wind or by ocean current, performing long migrations relying on vector navigation is particularly challenging. We tested whether vector navigation could be involved in the migrations of green turtles (Chelonia mydas) that migrate between...
