“…Seasonality studies are usually conducted as part of a program of standardization and qualification of raw material and apiceutical products. Researchers worldwide have discussed the challenge of standardization of apiculture products and based on propolis raw material 6,7 , some factors are known like as geographical area 3,6–8 , vegetation type and botanical origin 1–3,8,9 ,0, climate changes with heat wave and prolonged droughts 10–12 , weather 10–12 , type of bee and queen-bee genetics 10–14 , hives management 12 , harvesting time 12 . However, the problem of standardization and variability remain the same in decades of study 6–8 .…”

The standardization of apiceutical products like as propolis extracts has been widely debated worldwide and variations in the propolis chemical composition are still very relevant topics for use-standardized of different propolis-type as medication by much of the world’s population. The present manuscript discuss important issues related to the climate effect and variations in propolis metabolite-profiling changes, antioxidant capacity and variations of the antibacterial activity of the Brazilian red propolis metabolites using comprehensive multivariate correlations. It was observed the increasing of guttiferones concentrations during the intense drought period and drastic decreasing in rainy period. The climate variation induced the high concentration of flavonoids in rainy period with pronounced dropped in some rainy months. The Pearson´s analysis demonstrated correlation between IC50 from DPPH and guttiferones and flavonoids concentrations. The PCA-X and Hotelling T2 test showed outliers during the months with lowest concentrations of formononetin and isoliquiritigenin was observed in antibacterial tests. The PLS-DA, OPLS-DA and VIP analysis demonstrate guttiferone E, guttiferone B, liquiritigenin, naringenin are considered important substances responsible by anti-staphylococcal activity in red propolis composition during the rainy season and drought period, but a synergistic effect with other flavonoids and isoflavonoids are not ruled out.

“…The replacement of natural floral communities with crop and grazing lands can increase competition for food among bee species, or alternatively, decrease competition by eliminating natural refuges and wild bees altogether [4]. Changing climate and weather patterns may further limit nectar abundance [5], harming bee populations [6]. Honey bees therefore face diverse stressors in human agricultural environments, including the complex and significant effects of floral resource limitation.…”

“…Loss fractions of around 20% are commonly referred to in Central and northern Europe. However, in the area in which the study took place, the worst period is summer, which is long, very dry and registers very high temperatures that affect the colonies [25]. The years during which the study took place (2016 and 2017) are the ones reporting the hottest and driest registries since records exist [71], which may have implied heavier losses.…”

“…During very hot and dry years, the amount of honey accumulated by bee colonies in spring considerably reduces. This not only affects the profitability of beekeeping farms, but also threatens the survival of the bees during summer, resulting in a period of food scarcity in southern areas [24,25]. Contextually, this study was developed in Córdoba (W77M+V5 Córdoba, Spain).…”

In this study, the Wbee Sensor System was used to record data from 10 Iberian beehives for two years in southern Spain. These data were used to identify potential conditioning climatic factors of the internal regulatory behavior of the hive and its weight. Categorical principal components analysis (CATPCA) was used to determine the minimum number of those factors able to capture the maximum percentage of variability in the data recorded. Then, categorical regression (CATREG) was used to select the factors that were linearly related to hive internal humidity, temperature and weight to issue predictive regression equations in Iberian bees. Average relative humidity values of 51.7% ± 10.4 and 54.2% ± 11.7 were reported for humidity in the brood nest and in the food area, while average temperatures were 34.3 °C ± 1.5 in the brood nest and 29.9 °C ± 5.8 in the food area. Average beehive weight was 38.2 kg ± 13.6. Some of our data, especially those related to humidity, contrast with previously published results for other studies about bees from Central and northern Europe. Conclusively, certain combinations of climatic factors may condition within hive humidity, temperature and hive weight. Southern Iberian honeybees’ brood nest humidity regulatory capacity could be lower than brood nest thermoregulatory capacity, maintaining values close to 34 °C, even in dry conditions.
