never be a case to be made for a culture of academic complacency or the demolitionof the meritocracy. It can be fulfilling for kids to chase a ribbon, as long as it's a ribbon the childreally wants. And the very act of making that effort can bring out the best in anyone's work. ...
The researchers found mixed breed dogs lived longer than purebred pups. Genetic diversity is a likely explanation. The latter represents a smaller gene pool. That can lead to a heightened risk of deleterious hereditary and congenital conditions. It’s simply genetic roulette at work. Selective ...
For example, recent work has shown that many highly polygamous species are, in fact, monomorphic, whereas many putatively monogamous species are dimorphic. In this paper we break up sexual dimorphism into subcomponents and then use comparative analyses to examine the pattern of covariation between ...
Noakes did not check whether the oxygen uptake plateau occurs in suitable tests to measure on the mouth what happens in the muscles. Finally, it doesn't propose new tests for the encephalon role during maximal effort, as that is expected in scientific work. For all of these reasons, it is...

However, work in Greece suggests that 23% of females remate. We examine the willingness of female D. subobscura to remate in the laboratory in a range of conditions, using flies from both Greece and England. We make a distinction between pseudopolyandry, where a female remates after an ...
People who work with them often talk about first-, second-, and third-generation biofuels to distinguish between simple, traditional biofuels that have been used for a long time and the more complex, more advanced, and more efficient ones that are currently in development....
Migratory birds make decisions about how far to travel based on cost-benefit trade-offs. However, in many cases the net effect of these trade-offs is unclear. We sought to address this question by measuring feather corticosterone (CORTf), leucocyte profile, avian malaria parasite prevalence and...
term payoff," Blake says. "That's effort they have to expend right now, as opposed to going out to play with their friends. So, they have to make decisions about whether there's an immediate payoff that could be easier versus something that may or may not work out for the long term...
of male and female participation in warfare, building on some ofour previous workin this area. Our model looks at the consequences of going to war on a person's fitness, and for the fitness of their genetic relatives, to work out the probability that a person will join in the fighting....
