    For species to stay temporally tuned to their environment, they use cues such as the accumulation of degree-days. The relationships between the timing of a phenological event in a population and its environmental cue can be described by a population-level reaction norm. Variation in reaction norms along environmental gradients may either intensify the envi- ronmental effects on timing (cogradient variation) or attenu- ate the effects (countergradient variation). To resolve spatial and seasonal variation in species’ response, we use a unique dataset of 91 taxa and 178 phenological events observed across a network of 472 monitoring sites, spread across the nations of the former Soviet Union. We show that compared to local rates of advancement of phenological events with the advancement of temperature-related cues (i.e., variation within site over years), spatial variation in reaction normsPeer reviewe

    Ongoing climate change can shift organism phenology in ways that vary depending on species, habitats and climate factors studied. To probe for large-scale patterns in associated phenological change, we use 70,709 observations from six decades of systematic monitoring across the former Union of Soviet Socialist Republics. Among 110 phenological events related to plants, birds, insects, amphibians and fungi, we find a mosaic of change, defying simple predictions of earlier springs, later autumns and stronger changes at higher latitudes and elevations. Site mean temperature emerged as a strong predictor of local phenology, but the magnitude and direction of change varied with trophic level and the relative timing of an event. Beyond temperature-associated variation, we uncover high variation among both sites and years, with some sites being characterized by disproportionately long seasons and others by short ones. Our findings emphasize concerns regarding ecosystem integrity and highlight the difficulty of predicting climate change outcomes. The authors use systematic monitoring across the former USSR to investigate phenological changes across taxa. The long-term mean temperature of a site emerged as a strong predictor of phenological change, with further imprints of trophic level, event timing, site, year and biotic interactions.Peer reviewe

    Chronicles of nature calendar, a long-term and large-scale multitaxon database on phenology

    We present an extensive, large-scale, long-term and multitaxon database on phenological and climatic variation, involving 506,186 observation dates acquired in 471 localities in Russian Federation, Ukraine, Uzbekistan, Belarus and Kyrgyzstan. The data cover the period 1890-2018, with 96% of the data being from 1960 onwards. The database is rich in plants, birds and climatic events, but also includes insects, amphibians, reptiles and fungi. The database includes multiple events per species, such as the onset days of leaf unfolding and leaf fall for plants, and the days for first spring and last autumn occurrences for birds. The data were acquired using standardized methods by permanent staff of national parks and nature reserves (87% of the data) and members of a phenological observation network (13% of the data). The database is valuable for exploring how species respond in their phenology to climate change. Large-scale analyses of spatial variation in phenological response can help to better predict the consequences of species and community responses to climate change.Peer reviewe

    The paper describes a study by the example of processing the results of a survey of 200 employees of the agro-industrial complex on psychological tests, work experience and salary level. The authors identified the following groups of competencies: intellectual and educational, communicative, motivational and volitional, management. 15 psychological tests were used to assess their presence in respondents. After correlation and variance analyses, a statistically significant model of the dependence of the wage level on 12 indicators was obtained: ability and readiness for self-development and self-education, tolerance, high motivation for success, self-actualization of personality, strong interest in professional development, focus on interaction, high level of emotional intelligence. At the same time, it can be used in research only for the agricultural complex at the current time, i.e., at the beginning of the sixth technological order

    Increasing the staff use efficiency in consumer cooperatives: current trends in conditions of digitization of agriculture

    The purpose of the study is to identify current trends in increasing the efficiency of using the personnel of consumer cooperation organizations. This, along with other sectors of the economy, performs the functions of the third stage of the economic reproduction process (exchange), and the third sphere of the agro-industrial complex sectors that complete the production process in the sphere of commodity circulation. The personnel of economic entities carry out procurement, transportation, processing, storage and marketing of products to end consumers. In the context of existing demographic problems, the decline of the rural population, the challenge is to increase the efficiency of using the part of the economically active population employed in the diversified activities of consumer cooperation. A long-term study of the functioning of cooperatives made it possible to accomplish the purpose of this study. This concerns the development of ways to increase the efficiency of using the personnel of cooperative organizations – preliminary measures. Such measures include training and retraining of specialists, advanced training of workers in cooperative higher and secondary vocational educational institutions, and subsequent ones as a result of the creation of integrated complexes, using modern equipment, new technologies and digitalization advances, providing for the efficient use of personnel. As a new trend, the training of specialists who work with cooperative members is proposed. The economic participation of members will have a positive impact on the performance of their cooperative and increase the efficiency of the use of personnel of consumer cooperation organizations

    Differences in spatial versus temporal reaction norms for spring and autumn phenological events

    For species to stay temporally tuned to their environment, they use cues such as the accumulation of degree-days. The relationships between the timing of a phenological event in a population and its environmental cue can be described by a population-level reaction norm. Variation in reaction norms along environmental gradients may either intensify the environmental effects on timing (cogradient variation) or attenuate the effects (countergradient variation). To resolve spatial and seasonal variation in species' response, we use a unique dataset of 91 taxa and 178 phenological events observed across a network of 472 monitoring sites, spread across the nations of the former Soviet Union. We show that compared to local rates of advancement of phenological events with the advancement of temperature-related cues (i.e., variation within site over years), spatial variation in reaction norms tend to accentuate responses in spring (cogradient variation) and attenuate them in autumn (countergradient variation). As a result, among-population variation in the timing of events is greater in spring and less in autumn than if all populations followed the same reaction norm regardless of location. Despite such signs of local adaptation, overall phenotypic plasticity was not sufficient for phenological events to keep exact pace with their cues-the earlier the year, the more did the timing of the phenological event lag behind the timing of the cue. Overall, these patterns suggest that differences in the spatial versus temporal reaction norms will affect species' response to climate change in opposite ways in spring and autumn
