“…Since the commercial success of livestock companies often depends on the homogeneity of animal performance, the selection to reduce environmental variability around an optimum production level, known as canalisation, has been a major focus for research in animal production. Some genes controlling environmental variability of traits were found to be different from those controlling the trait [28] and experimental results have confirmed the existence of plasticity genes [4,9,21]. Moreover, the interest in canalisation has increased due to the recent publication of evidence identifying molecular mechanisms [14] affecting canalisation in Arabidobsis thaliana [20] and D. melanogaster [25].…”

“…The modelling of environmental variability is based on the hypothesis of the existence of a pool of genes controlling the mean of the performance and another pool of genes controlling the variability when the environment is modified [28]. SanCristobal-Gaudy et al [26] have proposed a model to deal with genetics of variability together with an EM-REML algorithm to estimate all the parameters simultaneously.…”

-The aim of this research was to explore the genetic parameters associated with environmental variability for litter size (LS), litter weight (LW) and mean individual birth weight (IW) in mice before canalisation. The analyses were conducted on an experimental mice population designed to reduce environmental variability for LS. The analysed database included 1976 records for LW and IW and 4129 records for LS. The total number of individuals included in the analysed pedigree was 3997. Heritabilities estimated for the traits under an initial exploratory approach varied from 0.099 to 0.101 for LS, from 0.112 to 0.148 for LW and from 0.028 to 0.033 for IW. The means of the posterior distribution of the heritability under a Bayesian approach were the following: 0.10 (LS), 0.13 (LW) and 0.03 (IW). In general, the heritabilities estimated under the initial exploratory approach for the environmental variability of the analysed traits were low. Genetic correlations estimated between the trait and its variability reached values of -0.929 (LS), -0.815 (LW) and 0.969 (IW). The results presented here for the first time in mice may suggest a genetic basis for variability of the evaluated traits, thus opening the possibility to be implemented in selection schemes.canalisation / variability / mice / litter size / litter weight

“…We sampled seven and nine populations of Solidago canadensis, a North American native that is invasive in China, along a latitudinal (temperature variability) and a longitudinal (precipitation variability) gradient, respectively, in China, and grew them under two temperature treatments and two water-availability treatments, respectively. Among the four traits with significant variation in plasticity among populations in response to temperature, plasticity of leaf length-to-width ratio was phenotypic plasticity can evolve in response to environmental variability (Scheiner and Lyman 1991;van Kleunen and Fischer 2005), few studies have addressed whether this might have happened during the spread of invasive plants to different latitudes and longitudes (Molina-Montenegro and Naya 2012).…”

significantly positively correlated with latitude and temperature seasonality of the populations. In addition, root/shoot ratio and water-use efficiency showed significant variation in plasticity among populations in response to water availability, and plasticities of these two traits were significantly negatively correlated with longitude and positively correlated with precipitation seasonality. The observed geographic clines in plasticity suggest that phenotypic plasticity of S. canadensis may have evolved rapidly in regions with different climatic conditions, and this may have contributed to the spread of this invasive species.

Divergence among species and populations of Mediterranean pines in biomass allocation of seedlings grown under two watering regimes

-Seedlings of four populations each of Pinus pinaster, P. halepensis, P. canariensis and P. pinea were grown in controlled conditions to evaluate both inter-and intra-specific differences in response to watering. We submitted half of the plants to a moderate water stress and after 22 weeks, we recorded height, stem diameter and root, stem and leaves dry weight. Patterns and amounts of phenotypic changes, including changes in biomass allocation, were analysed. We found a scant response in P. canariensis, P. pinaster and P. halepensis presented high population divergence for phenotypic changes, and P. pinea showed marked allocational shifts and no population divergence. The phenotypic changes observed within species are interpreted as a plastic response. The variation encountered within P. halepensis and P. pinaster may be indicative of specialisation to either resource-rich or resource-poor habitats, being populations from favourable sites more plastic. P. pinea exhibited a very uniform plastic response, indicating generalist behaviour.phenotypic changes / early testing / pine / drought stress / ontogeny Résumé -Divergences parmi les espèces et populations de pins méditerranéens pour l'allocation de biomasse chez des semis poussant sous deux régimes d'alimentation hydrique. Des semis de quatre populations de Pinus pinaster, de P. halepensis, de P. canariensis, et de P. pinea ont été élevés en conditions contrôlées pour évaluer au niveau inter-et intra-spécifique les différences de réponse au régime d'alimentation hydrique. Nous avons soumis la moitié des plants à un stress hydrique modéré et après 22 semaines nous avons mesuré leur hauteur, le diamètre de la tige et des racines, le poids sec de la tige et des feuilles. Les modèles et l'importance des changements phénotypiques, incluant les variations d'allocation de biomasse ont été analysés. Nous avons trouvé une faible réponse pour P. canariensis ; P. pinaster et P. halepensis ont présenté une importante divergence des populations au plan des changements phénotypiques, et P. pinea a montré une modification sensible au plan de l'allocation de biomasse sans divergence de population. Les changements phénotypiques observés chez les espèces ont été interprétés comme une réponse en terme de plasticité. Les variations rencontrées chez P. halepensis et P. pinaster peuvent être l'indice d'une spécialisation pour des habitats riches ou pauvres en terme de ressources. P. pinea a présenté une plasticité uniforme de réponse, révélant un comportement généraliste. changements phénotypiques / test précoce / stress hydrique / ontogénie
