This paper demonstrates the importance of the reception and development of Goethe's metamorphosis of plants as a methodological and philosophical framework in the history of botanical theories. It proposes a focus on the textbooks written by the German botanist Ludwig Reichenbach and his first attempt to use Goethe's idea of metamorphosis of plants as fundamental to his natural system of plants published under the title 'Botany for Women', in German Botanik für Damen (1828). In this book, Reichenbach paid particular attention to Goethe's sensitive views on the essence of nature; he regarded Goethe's idea of metamorphosis in the plant kingdom as an ideal model to interpret connections of natural phenomena, in particular as a conceptual frame for a natural system. Furthermore, he aimed to develop the philosophical statement of the metamorphosis, in which he called for nature-philosophical conceptions in order to materialize his representation of plant "affinities," and of a kind of "ontogeny" of the whole plant kingdom. This paper demonstrates that, between speculative views and empirical attempts, the extent to which Reichenbach actually belonged to a new "school" of thought, which left its mark on the history and philosophy of botany

Jean‐Daniel Buchinger (1803‐1888) est de ces hommes qui ont œuvré toute leur vie au service de la science et de la communauté scientifique, sans pour autant que leurs noms passent à la postérité. Inspecteur des écoles primaires du Bas‐Rhin puis directeur de l'orphelinat de Strasbourg, il est surtout connu par la communauté scientifique comme botaniste. J.‐D. Buchinger est au centre d'un réseau franco‐allemand d'échanges d'herbiers et d'ouvrages de sciences naturelles. La correspondance de cet érudit strasbourgeois du 19ème siècle témoigne de son rôle d'intermédiaire scientifique. La Bibliothèque Nationale et Universitaire de Strasbourg conserve plus de 15000 lettres adressées à J.‐D. Buchinger ou composant sa collection personnelle d'autographes. Il était nécessaire de créer une nouvelle entrée à cette source de manuscrits dont l'inventaire ci‐joint constitue une base de recherche pour l'historien.

This mini review examines the impact of tropical climate on motivational factors during aerobic performance and proposes the tracks of an integrative theoretical model to better understand the direct and indirect motivational mechanisms that can operate on athletic performances. TC is detrimental for aerobic performance and, although it clearly induces physiological constraints, these do not seem to be the only factors that explain the performance decline. Indeed, TC performance researchers have developed a theory of anticipation, which suggests that the brain commands a reduction in effort to protect the body from probable harm and heatstroke risk. The objective of this mini review is thus to examine the possibility that motivation may be a key factor in TC performance. The main psychological impacts of TC on aerobic performance are reviewed and an integrative theoretical model is presented that may help to better understand the mechanisms of motivation.

This research aim to investigate the effects of motor imagery, focused on the trajectory of the ball and the target area, and self-talk before the actual strike on the performance of the service in skilled tennis players. Thirty-three participants, competing in regional to national competitions, were randomly divided into three groups: Control, MI, and MI + self-talk. They performed a pre-test, 20 acquisition sessions, and a post-test similar to the pre-test, in match situations. The percentage of the first service, their speed, and the efficiency scores, evaluated by experts, were use as dependent variables and indicators of performance. While there was no difference in service speed, this study showed an improvement in the first service percentage and efficiency in the participants of the MI and MI + self-talk groups. Additionally, analyses revealed greater efficiency when MI was combined with self-talk compared to other conditions. It, therefore, seems advantageous for skilled tennis players to use MI and motivational self-talk before performing the first service balls.
