Despite the reputation of many large sharks as effective hunters, few studies have examined whether they follow any pattern in their foragingbehaviour.
"These chemicals have been shown to affect the foragingbehaviour of bees and damage bee brain function, " said Rachel Sharp, the chief executive officer of Wildlife Trusts Wales.
The advantage is that almost all the members of the colony can direct their energies towards foraging for food in order for the whole community to survive, rather than indulging in physically exhausting mating and reproductive behaviour.
