A manera de conclusión: del interés de estudiar la megadiversidad agraria del Ecuador Inra
Cochet, H.; Gasselin, P..
Al reunir ocho estudios de la agricultura de micro-regiones ecuatorianas, este libro anima a construir un análisis comparativo y a abogar por la implementación de una investigación de ámbito nacional. Ejemplares de la megadiversidad agraria que caracteriza el territorio ecuatoriano, los estudios ilustran las desigualdades abismales del desarrollo agrario, entre regiones y entre grupos sociales, así como la remanencia de una dualidad social secular.El presente artículo señala, a partir del ejemplo del minifundismo, cómo el análisis comparativo faculta la interpretación del movimiento general de una sociedad y alienta a caracterizar las similitudes y las diferencias entre los grupos sociales. La alta diversidad de las situaciones agrarias del Ecuador debe...

Agriculture méditerranéenne : les trois défis de la mondialisation Inra
Rastoin, J.L..
La Méditerranée a constitué, avec les empires grec, romain, puis ottoman, le foyer de puissantes « Économies-monde régionales » conceptualisées par Fernand Braudel (Braudel, 1985). L’Histoire n’a pas repassé les plats et les véritables mondialisations au sens d’une croissance planétaire des échanges humains, matériels et immatériels – la première entre 1870 et 1914, la seconde depuis 1980 – se sont faites autour d’autres pôles géographiques en captant dans leur périphérie les pays méditerranéens. La deuxième mondialisation, pour reprendre l’expression de Suzanne Berger du MIT (Berger, 2003), n’est plus une hypothèse, c’est devenu une réalité, avec de nouveaux flux d’échanges qui recomposent les territoires selon la théorie des archipels de Pierre Veltz :...

Aphids (Hemiptera, Aphididae) Inra
Coeur D'Acier, A.; Pérez Hidalgo, N.; Petrović-Obradović, O..
Our study aimed at providing a comprehensive list of Aphididae alien to Europe. A total of 98 species originating from other continents have established so far in Europe, to which we add 4 cosmopolitan species of uncertain origin (cryptogenic). Th e 102 alien species of Aphididae established in Europe belong to 12 diff erent subfamilies, fi ve of them contributing by more than 5 species to the alien fauna. Most alien aphids originate from temperate regions of the world. Th ere was no signifi cant variation in the geographic origin of the alien aphids over time. Th e average introduction rate was 0.5 species per year since 1800. Th e mean number of newly recorded species per year decreased since 2000 but this pattern may change in the following years.

Apport des connaissances fondamentales au contrôle du cycle reproducteur des poissons d'étang : limites et perspectives [The control of the reproductive cycle in pond fish: limits and perspectives] Animal Physiology
Breton, B.; Fostier, A.; Jalabert, B.; Weil, C..
Les possibilités d'un contrôle de la reproduction des poissons sont basées sur une bonne connaissance de la gamétogenèse, de son contrôle endocrinien et de son déroulement au cours du cycle reproducteur annuel. On examinera le rôle clé joué par le complexe hypothalamo-hypophysaire qui intègre les facteurs de l'environnement et répond en élaborant et sécrétant une ou plusieurs hormones impliquées dans le développement des gonades. Ces dernières vont, grâce à la sécrétion de stéroïdes sexuels, solliciter d'autres organes comme le foie, et mobiliser des réserves corporelles pour les intégrer sous forme de vitellus dans les ovocytes. Les facteurs de l'environnement susceptibles d'intervenir dans la régulation du cycle sexuel sont nombreux : facteurs physiques...

Artificial insemination in trout using a sperm diluant Animal Physiology
Billard, R.; Petit, J.; Jalabert, B.; Szollosi, D..
In the practice of artificial insemination in salmonids, efficiency is usually poor since one male is used to fertilize only a few females. Some attempts have been made to improve the efficiency of artificial insemination, either by using minute quantities of sperm or by diluting sperm. The use of small quantities of sperm allows fertilization of 24 females by one male (Nursall and Hasler, 1952). Sperm dilution, which was performed in saline by Scheuring (1925) and Nomura (1964), has been reported to improve the percentage of fertilized eggs when compared with results obtained following fertilization by pure milt (Poon and Johnson, 1970; Plosila et al., 1972). Ginsburg (19681, however showed that the dry method was the most efficient. Lately, we showed...
