This paper presents descriptions, and taxonomic and ecological data by the angiosperm pollen grains recovered from Quaternary sediments of the Gruta do Urso Cave, Tocantins State, Northern Brazil. Among recovered assemblage, 44 types of angiosperm pollen were identified. Most of the pollen types described here are related to the modern aboreal-shrub and herbaceous-subshrub taxa currently present in the plant communities of the Cerrado biome: (i) forest formations (Annonaceae, Aspidosperma, Ilex, Celtis, Trema, Tournefortia, Protium, Combretaceae-Melastomataceae type, Croton-type, Moraceae-Urticaceae type, cf. Bauhinia brevipes, Cassia, Pithecellobium, Peixotoa, and Cedrela); (ii) savannah formations (Anacardium, Astronium, Asteraceae Tribu Eupatorieae, Caryocar, Cyperaceae, Eriotheca-type, Ludwigia, Pseudobombax spp., Ouratea, Qualea, and Utricularia), and (iii) grasslands (Poaceae). Regarding the diversity of pollen types registered, the most representative botanical families were: Fabaceae (8), Malvaceae (4), Euphorbiaceae (3), Anacardiaceae (3), Apocynaceae (2), Cannabaceae (2), Sapindaceae (2) and Poaceae (2), which also occur in the Cerrado-Caatinga transition. Pollen data show paleovegetation during the Last Glacial Maximum and Holocene times out of the cave, and provides a reliable source for paleoecological, paleoenvironmental and paleoclimatic investigations. Keywords: palynology, Quaternary, paleovegetation, Brazilian savannah. Este artigo apresenta as descrições morfológicas, dados taxonômicos e ecológicos de grãos de pólen de angiospermas recuperados de sedimentos quaternários da Gruta do Urso, Estado do Tocantins, Norte do Brasil. Foram registrados 44 tipos polínicos que se relacionam com os táxons arbustivo-arbóreos e arbustivo-herbáceos ocorrentes atualmente nas comunidades vegetacionais do bioma Cerrado: (i) formações florestais (Annonaceae, Aspidosperma, Ilex, Celtis, Trema, Tournefortia, Protium, Tipo Combretaceae-Melastomataceae, Tipo Croton, Tipo Moraceae-Urticaceae, cf. Bauhinia brevipes, Cassia, Pithecellobium, Peixotoa e Cedrela); (ii) cerrado sensu stricto (Anacardium, Astronium, Asteraceae Tribo Eupatorieae, Caryocar, Cyperaceae, Tipo Eriotheca, Ludwigia, Pseudobombax spp., Ouratea, Qualea e Utricularia) e (iii) gramíneas (Poaceae). Quanto à diversidade polínica, as famílias botânicas mais representativas foram: Fabaceae (8), Malvaceae (4), Euphorbiaceae (3), Anacardiaceae (3), Apocynaceae (2), Cannabaceae (2), Sapindaceae (2) e Poaceae (2), que também ocorrem na transição dos biomas Cerrado-Caatinga. Os dados polínicos refletem a paleovegetação do entorno da caverna durante o Último Máximo Glacial e Holoceno, e constituem uma fonte confiável para as investigações paleoecológicas, paleoambientais e paleoclimáticas.

Background: This study examined the influence of creative thinking, shaped by different forms of episodic mental representations, on human movement. The primary objective was to investigate how creativity, elicited through distinct cognitive stimuli, affects movement variability. Methods: Twenty-four professional dancers developed two original dance phrases, each inspired by either a visual or a narrative mental representation. Movement data were collected via inertial sensor technology and subsequently analysed to determine differences in motor expression. Results: The results indicated that movements performed under narrative representation conditions exhibited significantly increased risk-taking behaviour, greater movement amplitude, and a higher overall movement volume compared to those guided by visual stimuli. Conclusions: These findings underscore the role of creativity in modulating both the expressive and physical dimensions of human movement. Moreover, this research demonstrates the potential of inertial sensor technology not only to capture kinematic patterns but also to provide insight into the deeper layers of human artistic and cognitive processes.
