Summary
[edit]DescriptionArctocephalus tropicalis Gauss reduite.png |
English: This diagram is depicting the number of birth according to the time during the breeding season in the subantarctic fur seal (Arctocephalus tropicalis) from the end of November to the start of January. On this diagram, you can see that the number of pup births follow a Gaussian distribution. The median date is matching with the middle of December. That means that the half of the births happen before the middle of December and the other half happen after this date. The median date is matching with the peak in the birthrate too. This diagram drew his inspiration from the figure 4 of the article from Georges, J.Y. and Guinet, C., « Early mortality and perinatal growth in the subantarctic fur seal (Arctocephalus tropicalis) on Amsterdam Island ». Journal of Zoology, London, 251, 277-287, 2000. The figure 4 of the Georges and Guinet's article is depicting the cumulative percentage of birth during the breeding season in 1996 and 1997 on Amsterdam island. In abscissa the dates are shown. The original figure isn't showing absolute informations but relative ones, that's why in the ordered (number of births), the unit isn't shown. This figure correspond to the picture Gauss_reduite.png from http://fr.wikipedia.org/wiki/Loi_normale modified according to the article aforesaid.
Français : Ce schéma représente le nombre de naissance en fonction du temps chez l'otarie subantarctique (Arctocephalus tropicalis) pendant la saison des parturitions qui a lieu de fin novembre à début janvier. Sur cette figure, vous pouvez voir que le nombre des naissances a une répartition qui suit la loi normale gaussienne. La date médiane correspond à la mi-décembre, c'est à dire que la moitié des naissance a lieu avant cette date et l'autre moitié a lieu après cette date. Cette date médiane correspond également au pic de naissance au cours de la saison de parturition. Cette figure est inspirée de la figure 4 de l'article de Georges, J.Y. et Guinet, C., « Early mortality and perinatal growth in the subantarctic fur seal (Arctocephalus tropicalis) on Amsterdam Island ». Journal of Zoology, London, 251, 277-287, 2000. La figure 4 de l'article de Georges et Guinet décrit le pourcentage cumulatif des naissances en fonctions du temps pour les saisons de reproduction 1996 et 1997 sur l'île d'Amsterdam. Sur l'axe des abscisses sont figurés les dates. La figure originelle présente des informations relative et non absolue, c'est pourquoi, pour les ordonnés (le nombre de naissance), l'unité n'est pas défini. Cette figure correspond à l'image Gauss_reduite.png tirée de la page http://fr.wikipedia.org/wiki/Loi_normale modifiée par l'auteur. |
