Trivers and Willard (1973) first proposed a verbal model for polygynous mammals in which a mother may allocate offspring to different sexes according to her condition: male-biased investment when she is in good condition and female-biased investment when she is in bad condition.
Altricial nestlings can increase begging behaviour and aggressiveness towards their siblings to improve energy intake and they may allocate resources to important processes in an hierarchical order [25], [26], but until the capacities of behavioural responses to challenges develop (e.g. around fledging) increased glucocorticoid secretion appears to be little beneficial.
Plants may allocate biomass to the structures and stimulate the AMF symbiosis to acquire more nutrients given the limited resources or vice versa (Johnson et al. 2013).
The higher dependence on water, which is a more unpredictable environment when compared to a burrow, together with no parental care, favors r-strategists, which may allocate energy to increase the number of eggs per clutch.
For multiantenna base stations with N A antennas, cellular scheduling proceeds similarly but may allocate up to N A users per frequency resource and base station, using cell-specific beamforming.
Conversely, species with a low dependency on water, in this case, egg-burrowing species, may allocate energy to parental care [ 35, 36].
It therefore seems that sexual conflict does not play a significant role in yolk androgen allocation but rather that females may allocate yolk androgens to adjust the growth trajectories of the chicks to poor growing conditions when for example mated with young males that are poor-quality providers or occupying a poor quality territory.
Although it is as yet speculative, these associations suggest that 7R+ individuals may allocate greater attention to appetitive rewards, contributing to the behavioral differences in promiscuity and infidelity observed here.
One police administrator, because of his personal beliefs or because of his perception of public opinion, may allocate more resources to certain types of crime or to certain police duties than to others.
Thus, compared to the average trematode species operating stolen host bodies, uninfected snails may allocate absolutely less to both direct reproductive output and to growth.
