Last year, hundreds of thousands of butterflies were found dead in another colony, raising concern that they had been intentionally killed with pesticides.
To test the adaptive significance of variation in innate colour bias, we compared the performance of colour-naïve bees, from nine bumblebee colonies raised from local wild-caught queens, in a laboratory colour bias paradigm using violet (bee UV-blue) and blue (bee blue) artificial flowers.
These data suggest that inbreeding depression may reduce the number of colonies raised by siblings over time.
Although they could not be compelled to serve overseas many volunteers subsequently did see action in a number conflicts of the British Empire during the 19th century, with the colonies raising contingents to serve in Sudan, South Africa and China.
However, SHFV has, to our knowledge, only been isolated from these species upon their arrival in primate colonies, raising the possibility of infection during transport.
When the lid on an ant colony is raised, a whiff of dead cockroach — ant chow — wafts by.
Rickettsia felis (R. felis) was first detected in 1990 in American Ctenocephalides felis fleas using electron microscopy, and named the ELB agent after the Elward laboratory (Soquel, CA) where the flea colony was raised [1].
Breeding pairs were obtained initially from the National Institutes of Health (Bethesda, MD) and in our colony were raised on a C57BL/6 background.
The Townshend Acts passed by Parliament in 1767 and imposing duties on various products imported into the British colonies had raised such a storm of colonial protest and noncompliance that they were repealed in 1770, saving the duty on tea, which was retained by Parliament to demonstrate its presumed right to raise such colonial revenue without colonial approval.
The threat of Indian conflicts in neighbouring colonies prompted the colony to raise its defensive profile, in which Endecott played a leading role.
