Changes in school structure according to external stimuli : description and influence on acoustic assessment IRD
Fréon, Pierre; Gerlotto, François; Soria, Marc.
The study of the internal school structure and behaviour of pelagic fish provides interesting information in relation to acoustic surveys, especially when comparing the undisturbed structure with the structure observed beneath a vessel passing over a school. The methodological approach involves in situ observations and combines acoustic and visual (aerial and underwater) techniques. The internal school structure is heterogeneous, including vacuoles, and this structure changes when the school is overpassed by a vessel during the day. In this case compression of the upper layer of the school is observed. The influence of this school structure on the variability of the density estimation has been studied. For the subsurface schools, the usual rate of sampling...

Conservation contre nature : les îles Galapagos IRD
Grenier, C..
L'introduction rappelle la valeur heuristique de l'insularité, d'où le parallèlé établi entre les îles et la planète à propos de l'évolution du monde contemporain. La première partie montre que la nature des Galapagos, si originale soit-elle, est en réalité devenue un espace, enjeu de multiples usages. L'objet du premier chapitre est double. Il décrit la nature des Galapagos : une géologie tumultueuse et des irrégularités climatiques dues aux fluctuations des courants océaniques rendent difficiles les colonisations naturelles et humaines : leurs paysages aux animaux et plantes caractéristiques varient selon l'altitude, l'exposition aux vents dominants et l'action de l'homme et des organismes qu'il a introduits dans l'archipel. Et ce chapitre explique la...

Dorsal abdominal glands in nymphs of southern green stink bug, Nezara viridula (L.) (Heteroptera: Pentatomidae): chemistry of secretions of five instars and role of (E)-4-oxo-2-decenal, compound specific to first instars Inra
Pavis, C.; Malosse, C.; Ducrot, P.H.; Descoins, C..
We investigated the exocrine secretions from the five nymphal instars in the southern green stink bug, Nezara viridula, by analyzing separately the contents of the three dorsal abdominal reservoirs. All DAGs 1 produced a mixture of five alkanes with 12, 13, 14, 15, and 16 carbons. No differences were found between DAGs 2 and DAGs 3, for the five instars: the glands of first instars produce the same alkanes as DAGs 1, n-tridecane, traces of (E)-2-decenal, and a specific compound: (E)-4-oxo-2-decenal. In the other instars (second to fifth), (E)-4-oxo-2-decenal is absent from the secretion but another compound is present: (E)-4-oxo-2-hexenal. The kinetics of production of the different compounds were studied, the maximum amounts produced occurring 36 hr after...

Ecology and social structure of Hypogeomys antimena, an endemic rodent of the dry deciduous forest in Western Madagascar IRD
Sommer, S..
La répartition géographique d'#Hypogeomys antimena$, le plus gros rongeur endémique de Madagascar, a été récemment limitée aux forêts sèches caducifoliées de l'Ouest de Madagascar. Entre 1992 et 1995 des méthodes de capture/repiégeage et de télémétrie ont permis le rassemblement de données indiquant que ces rongeurs vivent dans un système social monogame. L'importance du rayon de dispersion est déterminé par la saison, la présence d'une portée et par l'occurrence du prédateur principal, #Cryptoprocta ferox$. (Résumé d'auteur)

Ecosystem manipulation for increasing biological N2 fixation by blue-green algae (CYANOBACTERIA) in lowland rice fields IRD
Grant, I.F.; Roger, Pierre-Armand; Watanabe, I..
An introduction to the soil/floodwater ecosystem of lowland rice fields is given. Two primary consumers are particularly important in limiting the growth and N2-fixing activities of blue-green algae in irrigated rice ; the OSTRACODA (Class CRUSTACEA) and the PULMONATA (MULUSCA). Control of grazing by neem seeds AZADIRACHTA INDICA A. Juss and cultural practices enhanced BGA biomass and increased N2-fixation ten fold. Significant increases in rice grain protein occur if heterocystous algae bloom early in the rice cultivation cycle and grazing control is maintained over 40 days. A large positive N balance was obtained over 3 rice crops by using neem seeds to control grazing of BGA. Algal inoculants used in conjunction with grazer control failed to establish...
