  bibo_abstract:
  - The rate of gene flow across a hybrid zone may be reduced by the presence of a
    physical barrier, by a reduction of population density caused by reduced fitness
    of hybrids (the “hybrid sink” effect), and by linkage. If the reduction in hybrid
    fitness is not extreme, the strength of the barrier to gene flow caused by these
    effects is. Here, w is the width of the cline; ρ* is the carrying capacity; W̄*
    is the mean fitness of the population, excluding effects of density; R is the
    strength of density-dependent regulation; and r̄ is the harmonic mean recombination
    rate between the locus whose flow is being calculated, and loci under selection.
    +, 0 denote populations outside the hybrid zone, and at its centre, respectively.
    This relation is illustrated using data from hybrid ones in Bombina and Podisma,
    and its implications for interpretation of data from nature are discussed.@eng
