    A Major Locus Controls a Genital Shape Difference Involved in Reproductive Isolation Between Drosophila yakuba and Drosophila santomea

    International audienceRapid evolution of genitalia shape, a widespread phenomenon in animals with internal fertilization, offers the opportunity to dissect the genetic architecture of morphological evolution linked to sexual selection and speciation. Most quantitative trait loci (QTL) mapping studies of genitalia divergence have focused on Drosophila melanogaster and its three most closely related species, D. simulans, D. mauritiana, and D. sechellia, and have suggested that the genetic basis of genitalia evolution involves many loci. We report the first genetic study of male genitalia evolution between D. yakuba and D. santomea, two species of the D. melanogaster species subgroup. We focus on male ventral branches, which harm females during interspecific copulation. Using landmark-based geometric morphometrics, we characterized shape variation in parental species, F1 hybrids, and backcross progeny and show that the main axis of shape variation within the backcross population matches the interspecific variation between parental species. For genotyping, we developed a new molecular method to perform multiplexed shotgun genotyping (MSG), which allowed us to prepare genomic DNA libraries from 365 backcross individuals in a few days using little DNA. We detected only three QTL, one of which spans 2.7 Mb and exhibits a highly significant effect on shape variation that can be linked to the harmfulness of the ventral branches. We conclude that the genetic architecture of genitalia morphology divergence may not always be as complex as suggested by previous studies

    Don Quijote navega de nuevo: percepciones de una web desde la metodología del EAS

    Get PDF
    This research explores the pedagogical and motivational potential of Don Quixote with the support of ICT. It focuses on analyzing the perceptions of the use of a webpage of our own design in differentiated recipients. Emulating the three quixotic outputs, the evaluations are collected in three interest groups: teachers in training,  teaching professionals and students, in an educational line on the designed resource. Methodologically, the study is inspired by the perspective of SLE (Situated Learning Episodes) by merging the didactic treatment of the masterpiece of world literature with the use of information and communication technologies.Esta investigación explora el potencial pedagógico y motivacional de El Ingenioso hidalgo Don Quijote de la Mancha con el apoyo de las TIC. Pone el foco en analizar las percepciones del uso de un Recurso Educativo en Abierto, una web de diseño propio, en un universo heterogéneo de usuarios. Emulando las tres salidas quijotescas, se recogen las percepciones en tres grupos de interés: profesorado en formación,  expertos docentes en activo y alumnado preuniversitario, en una suerte de trazabilidad educativa sobre el REA. Metodológicamente la investigación se contextualiza en un Episodio de Aprendizaje situado (EAS) al fusionar el tratamiento didáctico del relato cervantino y las TIC

    Práctica docente y TIC: asociación indispensable en el presente siglo

    Get PDF
    Reflexionar sobre la integración de las tecnologías de la información y la comunicación en la práctica curricular es la intención de este artículo. Decir que las mis- mas suponen, hoy en día, un valor añadido (imprescindible) al proceso de enseñanza aprendizaje es hablar de una educación inmersa ya en el siglo XXI y, por tanto, en la sociedad actual. Exponemos, desde la práctica y la investigación contrastada, una re- flexión sobre el empleo de diversas herramientas de la Web 2.0. Sirven estas para potenciar tanto la interacción entre los miembros de la comunidad educativa como para promover un sistema de trabajo creativo , participativo y enormemente motivador

    Water Mass Transports and Pathways in the North Brazil- Equatorial Undercurrent Retroflection

    Get PDF
    The equatorial retroflection of the North Brazil Current (NBC) into the Equatorial Undercurrent (EUC) and its posterior tropical recirculation is a major regulator for the returning limb of the Atlantic Meridional Overturning Circulation. Indeed, most surface and thermocline NBC waters retroflect at the equator all the way into the central and eastern Atlantic Ocean, before they recirculate back through the tropics to the western boundary. Here, we use cruise data in the western equatorial Atlantic during April 2010 and reanalysis time series for the equatorial and tropical waters in both hemispheres in order to explore the recirculation pathways and transport variability. During the 1998–2016 period, the annual-mean EUC transports 15.1 ± 1.3 Sv at 32°W, with 2.8 ± 0.4 Sv from the North Atlantic and 11.4 ± 1.3 Sv from the South Atlantic. At 32°W most of the total EUC transport comes from the western boundary retroflection south of 3°N (7.2 ± 0.9 Sv), a substantial fraction retroflects north of 3°N (5.6 ± 0.4 Sv), and the remaining flow (2.3 Sv) joins through the interior basin. The South Atlantic subtropical waters feed the EUC at all thermocline depths while the North Atlantic and South Atlantic tropical waters do so at the surface and upper-thermocline levels. The EUC transport at 32°W has a pronounced seasonality, with spring and fall maxima and a range of 8.8 Sv. The 18 yr of reanalysis data shows a weak yet significant correlation with an Atlantic Niño index, and also suggests an enhanced contribution from the South Atlantic tropical waters during 2008–2016 as compared with 1997–2007En prensa3,17

    Speleoseismology and palaeoseismicity of Benis Cave (Murcia, SE Spain): coseismic effects of the 1999 Mula earthquake (mb 4.8)

    Get PDF
    This work describes the coseismic ceiling block collapse within Benis Cave (−213 m; Murcia, SE Spain), associated with the 1999 Mula earthquake (mb=4.8, MSK VII). The collapse occurred at −156 m into the Earthquake Hall, and as a consequence one small gallery became blind. We studied the geology, topography and active tectonic structures relevant to the cave. In addition, we carried out a seismotectonic analysis of the focal mechanism solutions, and also a fault population analysis on slickensides measured in fault planes in the cave. The stress and strain regime is interpreted as being congruent with the palaeoseismic evidence, and agrees with the fault kinematics established for cave galleries developed within fault planes and growth anomalies of coral flowstone. Our analysis suggests that one active segment (NNE–SSW) determined the morphology and topography of the Benis Cave, where strong to moderate palaeoearthquakes (6≤M≤7) took place. As a consequence of this intense seismic activity a small gallery collapsed. A new palaeoseismic structure, or seismothem, has been recognized, namely the effect of palaeoearthquakes affecting the pattern of development of the spatial coral flowstone distribution located at the bottom of the cave

    Differences between 1999 and 2010 across the Falkland Plateau: fronts and water masses

    Get PDF
    Decadal differences in the Falkland Plateau are studied from the two full-depth hydrographic data collected during the ALBATROSS (April 1999) and MOC-Austral (February 2010) cruises. Differences in the upper 100 dbar are due to changes in the seasonal thermocline, as the ALBATROSS cruise took place in the austral fall and the MOCAustral cruise in summer. The intermediate water masses seem to be very sensitive to the wind conditions existing in their formation area, showing cooling and freshening for the decade as a consequence of a higher Antarctic Intermediate Water (AAIW) contribution and of a decrease in the Subantarctic Mode Water (SAMW) stratum. The deeper layers do not exhibit any significant change in the water mass properties. The Subantarctic Front (SAF) in 1999 is observed at 52.2–54.8 W with a relative mass transport of 32.6 Sv. In contrast, the SAF gets wider in 2010, stretching from 51.1 to 57.2 W (the Falkland Islands), and weakening to 17.9 Sv. Changes in the SAF can be linked with the westerly winds and mainly affect the northward flow of Subantarctic Surface Water (SASW), SAMW and AAIW/Antarctic Surface Water (AASW). The Polar Front (PF) carries 24.9 Sv in 1999 (49.8–44.4 W), while in 2010 (49.9–49.2 W) it narrows and strengthens to 37.3 Sv.En prens
