On Pomacea canaliculata (Lamarck, 1822) (Mollusca; Pilidae: Ampullariidae)

This paper deals with the morphology of Pomacea caniculata (Lamarck, 1822) collected at Corrientes, Argentina. Comparison is made with Pomacea lineata (Spix, 1827) and Pomacea sordida (Swainson, 1823). The shell is globose, heavy, with greenish or horn-colored periostracum and dark spiral bands; apex subelevated, 5-6 whorls increasing rather rapidly and separated by very deep suture. Aperture large, rounded to subelongated; lip sometimes reddish; umbilicus large and deep; operculum corneous, entirely closing the aperture. Ratios: shell width/shell length = 0.78-0.96 (mean 0.86); aperture length/shell length = 0.68-0.77 (mean 0.72). Radula similar to other congeneric species. Testis and spermiduct as in P. lineata and P. sordida; prostate cylindric and short, cream in color as the testis. Penial sheath straight bearing a central outer gland deeply embedded in the tissue of its basal portion and a large wrinkled gland occupying 2/3 of the distal tip of its inner surface; the rigth margin of the sheath overlaps the left one until 2/3 of its proximal end. Female reproductive apparatus similar to that P. lineata; vestigial male copulatory apparatus (penis and its sheath) present in all females examined.

Dieu, vingt-six portraits bibliques

Vingt-six portraits par vingt-six exégètes. Tel est le défi proposé et assumé pour un parcours surprenant de lectures et d'interprétations multiples d'un Dieu unique et en même temps complexe. Quelle cohérence entre le Dieu fracassant de l'Exode et le Dieu crucifié de l'apôtre Paul ? Quelle continuité entre le Dieu de Gédéon et celui de Jésus : " Mon Dieu, mon Dieu, pourquoi m'as-tu abandonné ? " (Mc 15,34) ? Le Dieu de l'entrée en Canaan ressemble-t-il vraiment à l'Agneau immolé de l'Apocalypse ? Mais déjà, au sein de la Bible hébraïque, les trompettes de Jéricho côtoient le Serviteur souffrant d'Isaïe. Comment comprendre aujourd'hui cette diversité de la présence de Dieu dans la Bible, si ce n'est par la diversité des regards d'exégètes dont la lecture croisée des textes bibliques nous invite à renouveler notre compréhension de Dieu ?

Etude de la torpeur chez Suncus etruscus (Savi, 1822) (Soricidae, Insectivora) en captivité

Some aspects of torpor have been studied among captive Suncus etruscus by recording the nest temperature. Torpors show a circadian pattern and occur spontaneously or can be induced by food shortage. Body temperature can be controlled during torpor, remaining relatively high at low ambiant temperatures. At 20° C, spontaneous torpors seem to be less deep than induced tropors, but both show similar patterns at 5-8 ° C. Spontaneous torpors begin between 01°° and 06°°, whereas the onset of diet induced torpors seems to depend also on food exhausting. The rates of activity (A) and of torpor (T) show under constant conditions a daily variability. Increase of T is linked with a decrease of A and the relationship could agree with A(%) = Ao( 1-T/100), where Ao is daily rate of activity when T = 0. Occurence of torpor among other Soricidae, possible occurence among free living Suncus etruscus and energy saving are discussed
