The temporal partitioning hypothesis suggests that the evolution of different diel activity rhythms in animals might facilitate the coexistence between prey and predators. However, the temporal shift of habitat use induced by predation has rarely been observed. The study of such a mechanism is particularly relevant for introduced species because it might explain how native species can persist or decline in response to the presence of alien species. The introduction of fish into ponds inhabited by amphibians has severe consequences for their occurrence and abundance. Fish particularly affect an alternative newt phenotype, the paedomorph, which does not undergo metamorphosis and maintains larval traits such as gills at the adult stage. In a laboratory design, we assessed the diel patterns of habitat use in the 2 distinct morphological phenotypes of palmate newt (Lissotriton helveticus) in the presence or absence of goldfish (Carassius auratus). Both newt phenotypes avoided a risky habitat more in the presence than in the absence of fish. This habitat shift was more pronounced during the daytime (i.e., when the risk could be considered higher for the newts) than during nighttime. However, in contrast to metamorphs, paedomorphs showed less adaptive changes according to temporal risk and remained in their shelter for most of the time. Temporal and habitat partitioning at the diel scale between native and alien species might promote their coexistence, but diel change can also imply a cost in the overall reduction of the time allocated to essential activities, showing that species interactions remain complex.

A supposer que le concept de valeur soit un concept empirique, qui a sa source dans l'expérience, de quel type est l'expérience de la valeur? Dans les pages suivantes, je suggère qu’Ehrenfels et Meinong ont apporté certaines améliorations substantielles à la position de Brentano. Ces améliorations résident essentiellement dans les deux points suivants : (1) les volitions se caractérisent par une dimension « active » ou conative qui fait défaut aux sentiments, ce qui interdit de les ranger dans une seule et même « classe » de phénomènes psychiques ; (2) le concept de valeur trouve son origine empirique dans les volitions ou les phénomènes conatifs, non dans les sentiments ou phénomènes affectifs.

Le photogramme est, au cinéma, la plus petite unité de prise de vue. Image fixe, unité élémentaire du film, le photogramme forme la cellule figée d’un mouvement qui se reconstitue sous l’effet d’un défilement réglé (24 photogrammes/seconde) par le dispositif technique du cinéma. Image paradoxale en ce qu’elle reste invisible au spectateur malgré sa force iconique, le photogramme trouve cependant, dans le flux qui le conduit insensiblement à la disparition, certaines zones de visibilité qui en révèlent le caractère à la fois fragile et intensif. Nous allons donc envisager certaines pratiques ou certains usages du photogramme cinématographique, tout en essayant de dégager, au départ de ces pratiques, les éléments d’une théorie du photogramme, que Roland Barthes et Sylvie Pierre appelaient déjà de leurs vœux. Des protos-photogrammes et de leur usage scientifique chez Muybridge et Marey, aux usages artistiques contemporains, en passant par des pratiques publicitaires, promotionnelles ou analytiques, nous allons voir que le photogramme reste un objet singulier.

Hydrogeophysics has become a major field of research in the past two decades and time-lapse electrical resistivity tomography (ERT) is one of the most popular techniques to monitor passive and active processes in shallow subsurface reservoirs. Time-lapse inversion schemes have been developed to refine inversion results, but they mostly still rely on a spatial regularization procedure based on the standard smoothness constraint. In this paper, we propose to apply a covariance-based regularization operator in the time-lapse ERT inverse problem. We first illustrate the method for surface and cross-hole ERT with two synthetic cases and compare the results with the smoothness-constrained inversion (SCI). The examples show that the covariance–constrained inversions (CCI) better image the anomaly both in terms of shape and amplitude. Although more important in low-sensitivity zones, improvements are observed everywhere in the tomograms. Those synthetic examples also show that an error made in the range or in the type of the variogram model has a limited impact on the resulting image, which still remains better than SCI. The method is then applied to cross-borehole ERT field data from a heat tracing experiment, where the comparison with direct measurements shows a strong improvement of the breakthrough curves retrieved from ERT. The proposed method could be extended to the time dimension which would allow the use of CCI in 4D inversion schemes. [less ▲]
