Short Term Adaptation

Short-term adaptation to moving sinusoidal gratings results in a motion aftereffect which decays in time. The time decay of the motion aftereffect has been measured psychophysically, and it is found to depend on (i) the spontaneous recovery from the adapted state, and (ii) the contrast of the test grating. We have measured the decays for various test conditions. An extrapolation of the measurements allows us to obtain a decay which represents the time course of the spontaneous recovery of the direction-sensitive mechanisms.

Colour Signals

Variation in male nuptial colour signals might be maintained by negative frequency-dependent selection. This can occur if males are more aggressive towards rivals with locally common colour phenotypes. To test this hypothesis, we introduced red or melanic three-dimensional printed-model males into the territories of nesting male stickleback from two optically distinct lakes with different coloured residents. Red-throated models were attacked more in the population with red males, while melanic models were attacked more in the melanic male lake. Aggression against red versus melanic models also varied across a depth gradient within each lake, implying that the local light environment also modulated the strength of negative frequency dependence acting on male nuptial colour.

Abstract Background The limited tolerance of Saccharomyces cerevisiae to inhibitors is a major challenge in second-generation bioethanol production, and our understanding of the molecular mechanisms providing tolerance to inhibitor-rich lignocellulosic hydrolysates is incomplete. Short-term adaptation of the yeast in the presence of dilute hydrolysate can improve its robustness and productivity during subsequent fermentation. Results We utilized RNA sequencing to investigate differential gene expression in the industrial yeast strain CR01 during short-term adaptation, mimicking industrial conditions for cell propagation. In this first transcriptomic study of short-term adaption of S. cerevisiae to lignocellulosic hydrolysate, we found that cultures respond by fine-tuned up- and down-regulation of a subset of general stress response genes. Furthermore, time-resolved RNA sequencing allowed for identification of genes that were differentially expressed at 2 or more sampling points, revealing the importance of oxidative stress response, thiamin and biotin biosynthesis. furan-aldehyde reductases and specific drug:H+ antiporters, as well as the down-regulation of certain transporter genes. Conclusions These findings provide a better understanding of the molecular mechanisms governing short-term adaptation of S. cerevisiae to lignocellulosic hydrolysate, and suggest new genetic targets for improving fermentation robustness.

This article discusses one of the main problems of user identification by keyboard handwriting - short-term changes in the keystroke dynamics of users in connection with its psychophysical state, as well as changes over a long time associated with the formation of keystroke dynamics by a new user or when switching to a new device. A method for determining the phase of working capacity by the time characteristics of the keystroke dynamics is proposed.

В лекции рассмотрены общие представления об адаптации, основанные на классических работах Г. Селье, Ф.З. Меерсона, Н.А. Агаджаняна, а также особенности адаптивного ответа развивающегося организма. Рассмотрены механизмы срочной адаптации как мобилизации функциональных резервов организма. В качестве одного из механизмов долговременной адаптации представлена эпигенетическая регуляция, которая позволяет выбрать и реализовать программу экспрессии генов - в соответствии с этапом онтогенетического развития, или средовым окружением. В качестве ещё одного механизма долговременной адаптации рассмотрено воздействие на генетический материал. Приведены примеры формирования адаптивного ответа организма на физико-химические и климатогеографические стрессорные факторы. Отдельно проанализированы механизмы адаптивного ответа организма детей на факторы образовательной среды. The lecture addresses general ideas about adaptation based on classic studies by H. Selye, F.Z. Meerson, and N.A. Agadzhanyan and features of the adaptive response in a developing body. Mobilization of the functional reserve is considered as a mechanism of short-term adaptation. Epigenetic regulation is presented as one of mechanisms for long-term adaptation, which allows selecting and implementing a gene expression program consistent with the stage of ontogenetic development or the environment. Another mechanism of long-term adaptation is influence on the genome. The lecture provides examples of adaptation to physicochemical and climatic geographical stress factors. Mechanisms of the adaptive response to factors of the educational environment in children are analyzed separately.
