We present a life history model, based on the assumptions that juvenile survival follows a negative exponential function while fecundity gain increases linearly with time to maturity. This model predi
Why is sex ubiquitous when asexual reproduction is much less costly? Sex disrupts coadapted gene complexes; it also causes costs associated with mate finding and the production of males who do not the
Spatial abiotic heterogenity can result in divergent selection, hence might increase the magnitude of host-parasite local adaptation (the mean difference in fitness of sympatric versus allopatric host
