Environmental temperature has fitness consequences on ectotherm development, ecology and behaviour. Amphibians are especially vulnerable because thermoregulation often trades with appropriate water balance. Although substantial research has evaluated the effect of temperature in amphibian locomotion and physiological limits, there is little information about amphibians living under extreme temperature conditions. Leptodactylus lithonaetes is a frog allegedly specialised to forage and breed on dark granitic outcrops and associated puddles, which reach environmental temperatures well above 40 ˚C. Adults can select thermally favourable microhabitats during the day while tadpoles are constrained to rock puddles and associated temperature fluctuations; we thus established microhabitat temperatures and tested whether the critical thermal maximum (CTmax) of L. lithonaetes is higher in tadpoles compared to adults. In addition, we evaluated the effect of water temperature on locomotor performance of tadpoles. Contrary to our expectations, puddle temperatures were comparable and even lower than those temperatures measured in the microhabitats used by adults in the daytime. Nonetheless, the CTmax was 42.3 ˚C for tadpoles and 39.7 ˚C for adults. Regarding locomotor performance, maximum speed and maximum distance travelled by tadpoles peaked around 34 ˚C, approximately 1 ˚C below the maximum puddle temperatures registered in the puddles. In conclusion, L. lithonaetes tadpoles have a higher CTmax compared to adults, suggesting a longer exposure to extreme temperatures that lead to maintain their physiological performance at high temperatures. We suggest that these conditions are adaptations to face the strong selection forces driven by this granitic habitat.

Die Kunst der Moderne, insbesondere die Lyrik, entwickelt eine eigene ästhetische Konzeption der Bewegung, die mit der klassischen Vorstellung der Bewegung als räumlicher Veränderung eines Körpers in der Zeit bricht. Baudelaires À une Passante, Rimbauds Bateauivre und Paul Valérys Le Cimetière marin sind drei paradigmatische Texte der französischen Moderne, in denen Bewegung als zeiträumliches Kontinuum reflektiert und in der Dynamik der Sprache materialisiert wird. Die moderne Kunst, so erweist sich, ist selbst Bewegung und stiftet Bewegung. Sie wird zu einer Kunst des Werdens, nicht der Substanz, zu einer Kunst der reinen sinnlichen Wahrnehmung, nicht des Begriffes, zu einer Kunst der diskontinuierlichen Erlebnisse, nicht der Erfahrung.<br><br>The art of the modern age, particularly the lyric poetry, develops an own aesthetic conception of the movement which breaks with the classic idea of the movement as a spatial change of a body in time. Baudelaires À une Passante, Rimbauds Bateau ivre and Paul Valérys Le Cimetière Marin are three paradigmatic texts of the French modern age, in which movement is reflected as a time-space-continuum and materialized in the dynamic of language. Modern art is itself movement and causes movement. It becomes an art of the development, not sub- stance, an art of pure sensory perception, not concept, an art of discontinuous adventures, not experience.
