The population of a honeybee colony
Webb5 juni 2024 · According to a recent article in The Guardian, beekeepers across the US lost four in 10 of their honeybee colonies over the same time period – making this the worst winter on record for tracked bee populations, and has raised fresh concerns over the plight of these pollinators. WebbWe created a mathematically simple honeybee population model (HoPoMo) using difference equations to model the population dynamics and the resource dynamics of a honeybee colony. Our model emphasizes the importance of pollen supply and of brood cannibalism, an aspect that was neglected by other honeybee population models so far. …
