Juvenile hormone, but not nutrition or social cues, affects reproductive maturation in solitary alkali bees (Nomia melanderi).
Eusocial insect colonies are defined by extreme variation in reproductive activity among castes, but the ancestral conditions from which this variation arose are unknown. Investigating the factors that contribute to variation in reproductive physiology among solitary insects that are closely related to social species can help to fill this gap. We experimentally tested the role of nutrition, juv...
متن کاملBurying beetles
extraordinary financial pressures that the NIH currently experience threatens the US science enterprise. This not only puts extreme pressure on established scientists but makes it very difficult for young people to develop their research programs. The NIH have put in place mechanisms to make it easier for young people to obtain their first grant, but all this does is get new researchers through...
متن کاملBacterial Infection Increases Reproductive Investment in Burying Beetles
The Nicrophorus genus lives and breeds in a microbe rich environment. As such, it would be expected that strategies should be in place to counter potentially negative effects of the microbes common to this environment. In this study, we show the response of Nicrophorus vespilloides to the common soil bacterium, Bacillus subtilis. Phenoloxidase (PO) levels are not upregulated in response to the ...
متن کاملAge-specific reproductive investment in female burying beetles:
19 1. How much should an individual invest in reproduction as it grows older? Answering 20 this question involves determining whether individuals measure their age as the time 21 left for future reproduction or as the rate of deterioration in their state. Theory 22 suggests that in the former case individuals should increase their allocation of 23 resources to reproduction as opportunities for ...
متن کاملMale burying beetles extend, not reduce, parental care duration when reproductive competition is high.
Male parents spend less time caring than females in many species with biparental care. The traditional explanation for this pattern is that males have lower confidence of parentage, so they desert earlier in favour of pursuing other mating opportunities. However, one recent alternative hypothesis is that prolonged male parental care might also evolve if staying to care actively improves paterni...
