  • existence of mandibular directional asymmetry in the european wild boar sus scrofa linnaeus 1758
    Journal of Morphological Sciences, 2014
    Co-Authors: Peremiquel Pares Casanova
    Abstract:

    We studied a sample of 37 dentulous dry mandibles from European wild board (Sus scrofa) and compared both the right and left sides in their Dorsal Aspect. To study the influence of age, the samples were grouped according to dental status: "subadults" (erupting 3rd M, n=22) and "adults" (fully erupted 3rd M, n=15). Individual levels of asymmetry were analysed from x- and y-coordinates of the 16 landmarks on the Dorsal Aspect of the mandible. Results. The analysis separated directional asymmetry (one side of the body with a larger character value than the other) and fluctuating asymmetry (small random deviations from perfect symmetry), which were both found to be significant. Conclusion. The condylar ramus was the most asymmetric structure for both age groups.

  • geometric morphometric on Dorsal Aspect of skull does not differences between horned and polled domestic goats
    2013
    Co-Authors: Peremiquel Pares Casanova
    Abstract:

    Few previous studies have explored caprine skulls using geometric morphometric (GM) methods, which enable the quantitative analysis and visualisation of shape changes in skeletal elements and provide an important compliment to traditional lineal analyses. The aim of this research is to determine whether GM techniques can provide insights into how the shape of the goat skull differs between horned and polled animals, focusing on the differences between the Dorsal Aspects of the neurocranium. Fourteen skulls (4 polled and 10 horned) skulls from adult goats belonging to different breeds were studied. From the obtained results, neither the size nor shape showed statistically significant differences between polled and horned skulls. As animal"s functional capabilities are influenced by the presence of horns (if horns must function as shock absorbers, protecting the brain from blows during intraspecific combat, it would seem that some differences in shape and/or size should be detected), it seems plausible to assume that landmarks located on the Dorsal Aspect of the neurocranium are not useful to detect those differences between horned and polled goats.

  • an analytical model of acoustic fish reflection for estimation of maximum Dorsal Aspect target strength
    Canadian Journal of Fisheries and Aquatic Sciences, 1991
    Co-Authors: M L Thiebaux, P R Boudreau, L M Dickie
    Abstract:

    We develop a simple analytical model of the acoustic reflectivity offish targets based on empirical observations in field and laboratory settings. It enables unbiased estimation of maximum Dorsal Aspect target strength in cases where individual fish are observed a minimum of three times in successive pings of a survey transect. The model results are consistent with observations of example fish targets of two demersal species. It promises improved estimates of target strength from field measurements.
