    Bee colony weight dynamics during passive wintering period
    (Estonian University of Life Sciences, 2026) Zacepins, A.; Komasilova, O.; Kotovs, D.; Komasilovs, V.; Gailis, J.; Tikuma, B.
    Honeybees (Apis mellifera) are essential for maintaining ecological balance and enhancing agricultural productivity through their pollination services. Gaining insight into the internal conditions of a honeybee colony is crucial for evaluating its health, productivity, and seasonal dynamics. In the northern countries bee colony activity is divided into two periods: active summer and winter passive periods. Monitoring the weight of honey bee colonies provides valuable insight into their physiological status, food consumption, and survival potential during wintering. This study investigates the weight dynamics of bee colonies throughout the passive wintering period, aiming to better understand colony metabolism and resource utilization under low-activity conditions. Continuous weight measurements were recorded using electronic hive scales. The data were analysed to assess temporal trends in colony mass loss and to identify environmental or management factors influencing these changes. Results showed a gradual decrease in hive weight corresponding to the consumption of stored honey, with the rate of loss varying in response to external temperature fluctuations and colony strength. These findings contribute to improving winter management practices by providing quantitative parameters of weight consumption for assessing colony health and predicting overwintering success.

    Importance of GIS solutions for beekeepers: a review
    (Estonian University of Life Sciences, 2023) Kotovs, D.; Zacepins, A.
    In today's realities, beekeeping encounters a number of different challenges, including the lack of suitable areas, urbanisation, intensive farming methods etc. In order to meet the current needs, modern beekeeping uses various information technology solutions that support beekeepers in their activities. Among such solutions, the use of geographic information systems and spatial data is relevant. At the time of writing this work, its authors are developing software solution for beekeepers based on Geographic Information System (GIS) and an interactive map within the scientific project named Hiveopolis. To further develop this solution, it is necessary to investigate the current situation related to issues in modern beekeeping and the solutions already available. In this study, a detailed review of solutions was carried out, which, according to the authors, are the most similar in subject matter to their developed solution. During the review, the authors studied the actual problems of beekeeping solved with the help of the considered solutions, and also provided possible ways to improve existing solutions, presenting their developed system. As a result, the study confirmed the relevance of this direction, and also made it possible to identify challenges for beekeeping and possible improvements to existing solutions.
