‟The key to resilient beekeeping is to harness the power of nature to restore harmony and balance inside the honey bee colony and between the colony and the environment”

Pollinator ecology

Can we predict the landscape pollinator carrying capacity and the competition with wild pollinators?

1

Resilience to climate and heat stress

Can we predict the effects of climate change on beekeeping based on genetics?

Genetic markers associated with heat resistance?

Can we design novel beehive types based on in-hive thermoregulation?

1
Genome sequencing:
2 parallel north-south transects
  • estimate the genomic offset = degree of maladaption under future climate change scenarios
  • maps of genomic vulnerability
2
Genetic basis of Critical Temperature max/min
  • CTmax/min assays at 10 partner institutions
  • making hybrids by crossings
  • segregation of opposite alleles
  • genome sequencing
  • seeking for associated single nucleotide variants
3
Impact of heat stress on reproductive success honey bee/varroa
4
Thermal interactions empty/inhabited hives
  • numerical model: simulates in-hive climate
  • hive monitoring technologies: experimental data
  • prediction of critical temperatures > alerts send to beekeeper
5
Field test: wood materials/coatings for hive building

Local adaptation by Darwinian selection

What are the characteristics of a Darwinian colony?

What is the impact of mobility of beekeeping sector?

1
Genetic characterization of established D-colonies
2
Follow-up colonies during process D-selection
  • phenotypic data: colony strength, honey yield
  • genome sequencing: candidate genes associated with colony survival
  • hive monitoring technologies: BEEP base
  • accelerometer/electromagnetic shaker: vibrational signature
3
Testing the genotype-environment interaction theorem

Immune resilience

Can we develop a novel haemocyte typology based on surface determinants?

What is the impact of heat and nutritional stress on the cellular and humoral immune potential of HBs?
