text: "In continuous populations with local migration, nearby pairs of individuals
have on average more similar genotypes\r\nthan geographically well separated pairs.
A barrier to gene flow distorts this classical pattern of isolation by distance.
Genetic similarity is decreased for sample pairs on different sides of the barrier
and increased for pairs on the same side near the barrier. Here, we introduce
an inference scheme that utilizes this signal to detect and estimate the strength
of a linear barrier to gene flow in two-dimensions. We use a diffusion approximation
to model the effects of a barrier on the geographical spread of ancestry backwards
in time. This approach allows us to calculate the chance of recent coalescence
and probability of identity by descent. We introduce an inference scheme that
fits these theoretical results to the geographical covariance structure of bialleleic
genetic markers. It can estimate the strength of the barrier as well as several
demographic parameters. We investigate the power of our inference scheme to detect
barriers by applying it to a wide range of simulated data. We also showcase an
example application to a Antirrhinum majus (snapdragon) flower color hybrid zone,
where we do not detect any signal of a strong genome wide barrier to gene flow."
