Abstract
Stressors may lead to a shift in the timing of life-history events of species causing a mismatch with optimal environmental conditions, potentially reducing fitness. In honeybees, the timing of brood rearing and nest emergence in late winter/early spring is critical, as colonies need to grow fast after winter to prepare for reproduction. However, the effects of stress on these life-history events in late winter/early spring and the possible consequences are not well understood. Therefore, we tested whether (1) honeybee colonies shift timing of brood rearing and nest emergence as a response to stressors, and (2) if there is a consequent loss of social resilience, reflected in colony fitness (survival, growth and reproduction). We monitored stressed (high load of the parasitic mite Varroa destructor or nutrition-restricted) colonies and presumably non-stressed colonies from the beginning of 2020 till the spring of 2021. We found that honeybee colonies do not shift the timing of brood rearing and nest emergence in spring as a coping mechanism to stressors. However, we show that there is a loss of social resilience in stressed colonies, leading to reduced growth and reproduction. Our study contributes to a better understanding of the effects of stressors on social resilience in eusocial organisms.

Usage notes
In-hive temperature - Figure 1a & Figure 2
In-hive temperature data, measured with sensors, used for the analysis of start of brood rearing (Figure 1a) and variance in in-hive temperature as a measure of socail resilience (Figure 2).
temperature- Figure 1a and Figure 2.csv
Includes data on
* colony id (colony)
* day (day of year), 1st of January 2021 is day 1
* mean in-hive temperature in celsius
* period of measurement: pre-brood (before start of brood rearing), brood (during brood rearing), post-cold (after cold shock experiment)
* treatments: control (presumably healthy colonies), varroa (high V. destructor infested colonies), pollen (pollen restricted colonies)
Foraging activity - Figure 1b
Dataset used for the analysis of daily total foraging activity of bees, collected from bee counters. Results are shown in Figure 1b.
