Bumblebee size polymorphism and worker response to queen pheromone
Queen pheromones are chemical signals produced by reproductive individuals in social insect colonies. In many species they are key to the maintenance of reproductive division of labor, with workers beginning to reproduce individually once the queen pheromone disappears. Recently, a queen pheromone that negatively affects worker fecundity was discovered in the bumblebee Bombus terrestris, presen...
متن کاملEstimation of bumblebee queen dispersal distances using sibship reconstruction method.
Dispersal ability is a key determinant of the propensity of an organism to cope with habitat fragmentation and climate change. Here we quantify queen dispersal in two common bumblebee species in an arable landscape. Dispersal was measured by taking DNA samples from workers in the spring and summer, and from queens in the following spring, at 14 sites across a landscape. The queens captured in t...
متن کاملWhich is which and who is who: Roger Waters up against Media
Pink Floyd was a British band whose work began in the late 60s. Roger Waters, the main contributor of the band, wrote almost all the lyrics and was also a main figure behind producing the motion picture of the album. He deliberately attacks Western media in both the lyrics he has written for the band and his solo projects. The present study finds this tendency of assaulting the media deeply roo...
متن کاملWeak and strong priming cues in bumblebee contextual learning.
Bees have the flexibility to modulate their response to a visual stimulus according to the context in which the visual stimulus is seen. They readily learn that in one context a yellow target, but not a blue one, should be approached to reach sucrose and that in another context blue, but not yellow, leads to sucrose. Here we contrast the bumblebee's ability to use two types of contextual or pri...
متن کاملTelomerase activity is maintained throughout the lifespan of long-lived birds.
Telomerase is an enzyme capable of elongating telomeres, the caps at the ends of chromosomes associated with aging, lifespan and survival. We investigated tissue-level variation in telomerase across different ages in four bird species that vary widely in their life history. Telomerase activity in bone marrow may be associated with the rate of erythrocyte telomere shortening; birds with lower ra...
