Forget hazy language about offers being contingent "on approved credit".
Fossil floras provide the only direct evidence of past tropical rain forest extent, but are contingent on the distribution of sampling sites, fossil identification and the vagaries of stratigraphy.
However, if sperm competitive ability is heritable, females A and B will benefit through the offspring sired by male M because of the inheritance of high absolute sperm competitive ability that will confer, on average and despite stochastic influences (contingent on the distribution of sperm competitiveness in the population of males), high fertilization success.
The strength and spatial configuration of selection driven by biotic interactions can change rapidly because they are contingent on the distributions and evolutionary trajectories of other organisms [ 17- 19].
These were referred to as 'hypothetical proteins' with or without the affix 'conserved' contingent on wider phylogenetic distribution [ 19].
Besides, the prospect of future tax increases that are contingent on changes in the distribution of wealth may not be as politically unlikely as it seems.
Given a heteroplasmy measurement from sampling h m, accurate preimplantation diagnosis is contingent on knowledge of the distribution P (h | h m ), that is, the probability that the embryonic heteroplasmy is h given that a measurement h m has been made.
As natural selection acts over time on the contingent initial distribution of species in different areas, completely distinct species eventually evolve.
Feelings of altruism, jealousy, etc. are ignored in order not to make the allocation of resources depend on the contingent distribution of benevolent and malevolent feelings among the population (see e.g. Goodin 1986, Harsanyi 1982).
The optimal choice between the two approaches will differ between settings contingent on a range of factors including the space time distribution of the data and prediction points, and the relative magnitudes of spatial and temporal autocorrelation.
Nonetheless, predicting the impacts of novel interactions is challenging, partly because many methods of inference are contingent on the current configuration of climatic variables and species distributions.
