Abstract

L'hybridation interspécifique entre le saumon atlantique et la truite commune dans la nature a été mise en évidence dans différents pays d'Europe et au Canada. Une étude a été entreprise pour examiner son incidence dans des populations de salmonidés de certaines rivières des Asturies (nord de l'Espagne) et du sud-ouest de la France. Elle a été complétée par des expériences en milieu contrôlé pour déterminer les causes et les conditions de la disparition des barrières comportementales permettant le maintien de l'isolement reproducteur. Les hypothèses de travail étaient que l'hybridation pouvait être favorisée par le comportement de «sneaker» des tacons mâles précoces et par les repeuplements en juvéniles des deux espèces. Les résultats obtenus confirment que l'hybridation entre la truite et le saumon est un phénomène répandu, qui peut affecter localement des fractions significatives des populations (9,4 % sur la rivière Narcea dans les Asturies). Dans l'aire originelle de distribution des deux espèces, le croisement s'effectue dans le sens femelle saumon x mâle truite. Dans les conditions normales de sympatrie, les barrières d'isolement reproducteur pré-appariement paraissent solides en raison du comportement agressif du mâle conspécifique dominant qui parvient à écarter efficacement les mâles compétiteurs hétérospécifiques. En l'absence de mâle conspécifique, l'hybridation peut avoir lieu. Cependant, les femelles modifient leur comportement, ralentissent leur activité de frai et le succès reproducteur, particulièrement chez la truite, diminue. Par ailleurs, les hypothèses de travail ne sont pas vérifiées. Pour éviter l'hybridation, il est recommandé au gestionnaire de veiller à la qualité et à la quantité des zones de reproduction, de maintenir l'équilibre des populations de géniteurs et de limiter les repeuplements en sujets non autochtones.

Abstract

Les îles Kerguelen (Terres Australes et Antarctiques Françaises) sont, à l'origine, vierges de toute espèce de poisson d'eau douce. Les quelques espèces de Salmonidés, introduites à la fin des années cinquante dans le cadre d'une politique d'occupation et de mise en valeur du Territoire, se sont acclimatées à l'environnement subantarctique et naturalisées avec plus ou moins de succès en fonction de leurs stratégies adaptatives respectives. Objet d'un suivi scientifique continu, ces populations apparaissent comme d'excellents modèles pour des études de génétique et de dynamique des populations. Les phénomènes de colonisation, limités dans un premier temps à l'augmentation régulière des densités de population et une extension rapide intra-rivière, ont connu un développement spectaculaire depuis les années quatre-vingt, à la suite des modifications importantes du climat local, dont l'influence sur les populations a été multiple. La vaste superficie de Kerguelen et les caractéristiques de ses réseaux hydrographiques permettent d'envisager de continuer à tirer parti positivement des introductions passées de Salmonidés, sur les plans scientifique et de mise en valeur du territoire, tout en développant une politique de protection des écosystèmes aquatiques et terrestres conforme à l'évolution actuelle des mentalités.

Abstract

Le risque d'introduction accidentelle du saumon coho dans les rivières peuplées par le saumon atlantique a conduit à développer des recherches en milieu expérimental sur les mécanismes de la compétition entre alevins et juvéniles des deux espèces. Les conséquences possibles de cette compétition ont été évaluées en termes de survie, croissance, prédation, dévalaison et occupation de l'habitat. Les résultats montrent que la présence des saumons cohos n'a pas une influence très marquée sur les alevins ou juvéniles de saumon atlantique si l'environnement trophique est favorable. La microdistribution est différente, les saumons atlantiques occupant plutôt les radiers alors que les saumons cohos préfèrent les profonds. Le comportement pélagique et grégaire des jeunes saumons cohos, nettement plus gros que les saumons atlantiques du même âge dès l'émergence, peut être opposé au comportement benthique et inféodé au substrat de ces derniers. Ces différences s'accentuent en sympatrie, aux dépens du saumon atlantique, désavantagé par la taille. Sous conditions trophiques limitantes, la croissance et la sédentarité des alevins de saumon atlantique sont significativement affectées par la présence des cohos, ce qui justifie d'émettre d'expresses réserves sur l'intérêt de l'introduction du saumon coho dans les rivières françaises.

Abstract

La réponse de juvéniles de saumon aux fortes baisses de niveau caractéristiques de l'étiage n'est pas bien connue. Trois expériences ont été menées en fin d'été dans un ruisseau artificiel comportant des séries de 3 biefs (10 m x 3 m) constitués d'amont en aval de séquences d'habitat radier, plat, profond. En eau profonde, les tacons ne réagissent pas aux baisses de niveau et de débit. Dans les eaux peu profondes, ils réduisent leur activité, en particulier alimentaire, et dans des conditions critiques, une partie de la population se déplace vers la plus proche zone profonde. Les autres s'enfouissent dans le substrat. Après la montée du débit, une partie des dévalants retourne dans l'habitat radier.

Abstract

Research has been conducted on male sneaking behavior of Atlantic salmon which leads to interspecific hybridization. Results demonstrate that this behavior helps sneaking Atlantic salmon males to fertilize brown trout ova in absence of brown trout males and that brown trout male aggressiveness towards sneaking salmon males and low survival of salmon sneaker hybrids are interspecific barriers.

Abstract

The complete 5.4 kton MINOS far detector has been taking data since the beginning of August 2003 at a depth of 2070 meters water-equivalent in the Soudan mine, Minnesota. This paper presents the first MINOS observations of νμ and ν̄μ charged-current atmospheric neutrino interactions based on an exposure of 418 days. The ratio of upward- to downward-going events in the data is compared to the Monte Carlo expectation in the absence of neutrino oscillations, giving Rup/downdata/Rup/downMC=0.62-0.14+0.19(stat.) ±0.02(sys.). An extended maximum likelihood analysis of the observed L/E distributions excludes the null hypothesis of no neutrino oscillations at the 98% confidence level. Using the curvature of the observed muons in the 1.3 T MINOS magnetic field νμ and ν̄μ interactions are separated. The ratio of ν̄μ to νμ events in the data is compared to the Monte Carlo expectation assuming neutrinos and antineutrinos oscillate in the same manner, giving Rν̄μ/νμdata/Rν̄μ/νμMC=0.96-0. 27+0.38(stat.)±0.15(sys.), where the errors are the statistical and systematic uncertainties. Although the statistics are limited, this is the first direct observation of atmospheric neutrino interactions separately for νμ and ν̄μ. © 2006 The American Physical Society.

Abstract

Un ruisseau artificiel expérimental (chenal de fraie) a été réalisé sur un affluent de la Haute Nivelle au Pays Basque. Le dispositif est caractérisé par un environnement quasi naturel où certains paramètres (débit, profondeur d'eau et vitesse du courant, granulométrie) peuvent être manipulés ou contrôlés. En décembre 1981, 5 couples de Saumon atlantique (Salmo salar L.) introduits dans le chenal ont frayé naturellement. Le nombre de frayères et la surface moyenne occupée par femelle ont été précisés, ainsi que la durée de formation d'une frayère. Des observations ont été faites sur le comportement de reproduction, la répartition des frayères et le taux de surcreusement dans des conditions de densité faible. L'influence de la vitesse du courant et de la température sur le déroulement de la fraie est suggérée. L'estimation de la fécondité et du taux de rétention d'ovules a permis d'évaluer le succès de la reproduction. Les résultats relatifs à la survie pendant l'incubation et aux modalités de l'émergence et de la dévalaison des alevins seront présentés dans un prochain article.

Abstract

Dans un chenal artificiel expérimental, des œufs de saumon atlantique (Salmo salar L.) ont été pondus naturellement ou ont été enfouis au stade embryonné. A la fin de la résorption de la vésicule, une fraction importante des alevins survivants dévale de la zone de frayère. La dévalaison semble stimulée par des baisses de niveau ou des hausses de température et ralentie en période de pleine lune. D'autres facteurs pouvant être responsables de cette dévalaison sont discutés. La survie jusqu'à la collecte de tous les alevins est estimée à 74 p. 100 pour les sujets issus de la reproduction naturelle et est égale à 80 p. 100 pour ceux issus d'œufs introduits dans le gravier au stade embryonné. Des comparaisons entre ces résultats et ceux obtenus dans d'autres chenaux de fraie ou en milieu naturel montrent la validité de cette méthode pour la production d'alevins de saumon atlantique destinés au repeuplement.

Abstract

We report the results of a search for nu(mu) disappearance by the Main Injector Neutrino Oscillation Search [D. G. Michael (MINOS), Phys. Rev. Lett. 97, 191801 (2006).]. The experiment uses two detectors separated by 734 km to observe a beam of neutrinos created by the Neutrinos at the Main Injector facility at Fermi National Accelerator Laboratory. The data were collected in the first 282 days of beam operations and correspond to an exposure of 1.27x10(20) protons on target. Based on measurements in the Near Detector, in the absence of neutrino oscillations we expected 336 +/- 14 nu(mu) charged-current interactions at the Far Detector but observed 215. This deficit of events corresponds to a significance of 5.2 standard deviations. The deficit is energy dependent and is consistent with two-flavor neutrino oscillations according to |Delta m(2)|=2.74(-0.26)(+0.44) x 10(-3) eV(2)/c(4) and sin(2)2 theta > 0.87 at 68% confidence level.

Abstract

We found 140 neutrino-induced muons in 854.24 live days in the MINOS far detector, which has an acceptance for neutrino-induced muons of 6.91x10(6) cm(2) sr. We looked for evidence of neutrino disappearance in this data set by computing the ratio of the number of low momentum muons to the sum of the number of high momentum and unknown momentum muons for both data and Monte Carlo expectation in the absence of neutrino oscillations. The ratio of data and Monte Carlo ratios, R, is R=0.65(-0.12)(+0.15)(stat)+/- 0.09(syst), a result that is consistent with an oscillation signal. A fit to the data for the oscillation parameters sin(2)2 theta(23) and Delta m(23)(2) excludes the null oscillation hypothesis at the 94% confidence level. We separated the muons into mu(-) and mu(+) in both the data and Monte Carlo events and found the ratio of the total number of mu(-) to mu(+) in both samples. The ratio of those ratios, R boolean AND(CPT), is a test of CPT conservation. The result R boolean AND(CPT)=0.72(-0.18)(+0.24)(stat)(-0.04)(+0.08)(syst) is consistent with CPT conservation.

Abstract

The 5.4 kton MINOS far detector has been taking charge-separated cosmic ray muon data since the beginning of August, 2003 at a depth of 2070 meters-water-equivalent in the Soudan Underground Laboratory, Minnesota, USA. The data with both forward and reversed magnetic field running configurations were combined to minimize systematic errors in the determination of the underground muon charge ratio. When averaged, two independent analyses find the charge ratio underground to be 1.374 +/- 0.004 (stat.) +0.012 -0.010(sys.). Using the map of the Soudan rock overburden, the muon momenta as measured underground were projected to the corresponding values at the surface in the energy range 1-7 TeV. Within this range of energies at the surface, the MINOS data are consistent with the charge ratio being energy independent at the two standard deviation level. When the MINOS results are compared with measurements at lower energies, a clear rise in the charge ratio in the energy range 0.3 -- 1.0 TeV is apparent. A qualitative model shows that the rise is consistent with an increasing contribution of kaon decays to the muon charge ratio., Comment: 16 pages, 17 figures

Abstract

The velocity of a ∼3GeV neutrino beam is measured by comparing detection times at the near and far detectors of the MINOS experiment, separated by 734 km. A total of 473 far detector neutrino events was used to measure (v-c)/c=5.1±2.9×10-5 (at 68% C.L.). By correlating the measured energies of 258 charged-current neutrino events to their arrival times at the far detector, a limit is imposed on the neutrino mass of mν

Abstract

The 5.4 kton MINOS far detector has been taking charge-separated cosmic ray muon data since the beginning of August, 2003 at a depth of 2070 m.w.e. in the Soudan Underground Laboratory, Minnesota, USA. The data with both forward and reversed magnetic field running configurations were combined to minimize systematic errors in the determination of the underground muon charge ratio. When averaged, two independent analyses find the charge ratio underground to be N-mu(+)/N-mu(-)=1.374 +/- 0.004(stat)(-0.010)(+0.012)(sys). Using the map of the Soudan rock overburden, the muon momenta as measured underground were projected to the corresponding values at the surface in the energy range 1-7 TeV. Within this range of energies at the surface, the MINOS data are consistent with the charge ratio being energy independent at the 2 standard deviation level. When the MINOS results are compared with measurements at lower energies, a clear rise in the charge ratio in the energy range 0.3-1.0 TeV is apparent. A qualitative model shows that the rise is consistent with an increasing contribution of kaon decays to the muon charge ratio.

Abstract

The complete 5.4 kton MINOS far detector has been taking data since the beginning of August 2003 at a depth of 2070 meters water-equivalent in the Soudan mine, Minnesota. This paper presents the first MINOS observations of νμ and ν̄μ charged-current atmospheric neutrino interactions based on an exposure of 418 days. The ratio of upward- to downward-going events in the data is compared to the Monte Carlo expectation in the absence of neutrino oscillations, giving Rup/downdata/Rup/downMC=0.62-0.14+0.19(stat.) ±0.02(sys.). An extended maximum likelihood analysis of the observed L/E distributions excludes the null hypothesis of no neutrino oscillations at the 98% confidence level. Using the curvature of the observed muons in the 1.3 T MINOS magnetic field νμ and ν̄μ interactions are separated. The ratio of ν̄μ to νμ events in the data is compared to the Monte Carlo expectation assuming neutrinos and antineutrinos oscillate in the same manner, giving Rν̄μ/νμdata/Rν̄μ/νμMC=0.96-0. 27+0.38(stat.)±0.15(sys.), where the errors are the statistical and systematic uncertainties. Although the statistics are limited, this is the first direct observation of atmospheric neutrino interactions separately for νμ and ν̄μ. © 2006 The American Physical Society.

Abstract

The complete 5.4 kton MINOS far detector has been taking data since the beginning of August 2003 at a depth of 2070 meters water-equivalent in the Soudan mine, Minnesota. This paper presents the first MINOS observations of nu(mu) and (nu) over bar (mu) charged-current atmospheric neutrino interactions based on an exposure of 418 days. The ratio of upward- to downward-going events in the data is compared to the Monte Carlo expectation in the absence of neutrino oscillations, giving R-up/down(data)/R-up/down(MC)=0.62(-0.14)(+0.19)(stat.)+/- 0.02(sys.). An extended maximum likelihood analysis of the observed L/E distributions excludes the null hypothesis of no neutrino oscillations at the 98% confidence level. Using the curvature of the observed muons in the 1.3 T MINOS magnetic field nu(mu) and (nu) over bar (mu) interactions are separated. The ratio of (nu) over bar (mu) to nu(mu) events in the data is compared to the Monte Carlo expectation assuming neutrinos and antineutrinos oscillate in the same manner, giving R-(nu) over bar mu/nu(data)(mu)/R-(nu) over bar mu/nu(MC)(mu)=0.96(-0.27)(+0.38)(stat.)+/- 0.15(sys.), where the errors are the statistical and systematic uncertainties. Although the statistics are limited, this is the first direct observation of atmospheric neutrino interactions separately for nu(mu) and (nu) over bar (mu).

Abstract

This Letter reports results from the MINOS experiment based on its initial exposure to neutrinos from the Fermilab NuMI beam. The rates and energy spectra of charged current nu(mu) interactions are compared in two detectors located along the beam axis at distances of 1 and 735 km. With 1.27x10(20) 120 GeV protons incident on the NuMI target, 215 events with energies below 30 GeV are observed at the Far Detector, compared to an expectation of 336 +/- 14 events. The data are consistent with nu(mu) disappearance via oscillations with vertical bar Delta m(32)(2)vertical bar=2.74(-0.26)(+0.44)x10(-3) eV(2) and sin(2)(2 theta(23))> 0.87 (68% C.L.).
