Here, we show that this zone is actually structured into local patches in which hybridization extends over an extremely irregular front. The distribution of hybrid-index (HI) scores across the transect reveals some hybridization at almost all localities mapped in a central 7 km x 3 km area. Pooling the central samples produces both a strong heterozygote deficit for all diagnostic markers and strong linkage disequilibria between all pairwise combinations of these (unlinked) markers. Moreover, a highly significant association exists between the habitat on which each individual was caught and its karyotype (F5 chromosomes are more likely to be found on oak). Analysis of genotype frequencies over a range of spatial scales shows that there is no significant heterozygote deficit or habitat association within local areas of less than about 200 m; however, there is significant linkage disequilibrium over the smallest scales (R = D (pquv)1/2 = 0.29, support limits, 0.18-0.36) over 100 m. These patterns suggest that lizards mate and choose habitats randomly within local patches. This conclusion is supported by mark-recapture estimates of dispersal (≈ 80 m in a generation) and by inference of matings from embryo and maternal karyotypes. Closer examination of the two-dimensional pattern reveals a convoluted cline for all three markers, with a width of 830 m (support limits 770 m-930 m). This cline width, combined with the strength of local linkage disequilibrium, implies a dispersal rate of σ = 160 m in a generation and an effective selection pressure of 30% on each chromosome marker. The proportion of inviable embryos is greater in females from the center of the hybrid zone; this is caused by effects associated with both karyotype and location. The hybrid zone is likely to be maintained by selection against chromosomal heterozygotes, by other kinds of selection against hybrids, and by selection adapting the chromosome races to different habitats. The structure of the contact may be caused by both random drift and by selection in relation to habitat.","lang":"eng"}],"external_id":{"pmid":["28593667"]},"pmid":1,"author":[{"last_name":"Sites","full_name":"Sites, Jack","first_name":"Jack"},{"orcid":"0000-0002-8548-5240","last_name":"Barton","full_name":"Barton, Nicholas H","first_name":"Nicholas H","id":"4880FE40-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Kent","last_name":"Reed","full_name":"Reed, Kent"}],"doi":"10.1111/j.1558-5646.1995.tb05955.x","oa_version":"Published Version","issue":"1","publication_status":"published","intvolume":"        49","extern":"1"},{"language":[{"iso":"eng"}],"date_published":"1995-12-01T00:00:00Z","type":"journal_article","publication_identifier":{"issn":["1558-5646"]},"year":"1995","day":"01","date_updated":"2022-06-28T07:47:30Z","volume":49,"title":"Appendix to \"A simulation study of multilocus clines\" by S J E Baird","citation":{"short":"N.H.

When hydrogen recombines on a surface, it deposits less than 4% of its energy at the point of recombination and the rest is carried off by the excited molecule. We have designed a maze to absorb most of this energy, and carried out a Monte Carlo simulation to show that approximately 87% of the energy is dissipated in the maze, preventing the surface from getting excessively heated, even at high surface densities. This simulation varies the number of inelastic collisions with the maze wall for complete relaxation, the fraction of elastic collisions, and the angular distribution of excited molecules desorbing from the walls.","lang":"eng"}],"author":[{"first_name":"M.
