This calculation applies in the limit where transitions are rare. Our results indicate that stochastic divergence is feasible despite free gene flow, provided that neighbourhood size is low enough. In two dimensions, the rate of transition depends primarily on neighbourhood size N and only weakly on selection pressure (≈sk exp(− cN)), where k is a number determined by the local population structure, in contrast with the exponential dependence on selection pressure in one dimension (≈exp(− cN √s)) or in a single deme (≈exp(− cNs)).

Using a simple model of disruptive selection on a polygenic character, we calculate the net probabilityofapeakshift. If the growth rate is high, theprobabilityofashiftina growing population is insensitive to selection on the character. Assuming that the character is effectively neutral during the brief initial increase, we find that theprobabilityofapeakshift is given by theprobabilityof finding a standard normal variate greater than √2ΔV where ΔV is the reduction in additive genetic variance during the growth period. This result holds for arbitrary pattern of increase in size, provided that the rate of increase is high enough for selection to be negligible, and the character depends on a large number of loci. Comparing theprobabilityofpeakshiftsin founding populations with the rate ofshiftsin static and allopatric populations it appears that although strongly selected shifts are only likely to occur ina growing population, a static population is a more congenial setting for adaptive shifts."}],"intvolume":" 126","title":"The probability of peak shifts in a founder population","status":"public","user_id":"ea97e931-d5af-11eb-85d4-e6957dddbf17","_id":"3656","oa_version":"None","publication_identifier":{"issn":["0022-5193"],"eissn":["1095-8541"]},"month":"05","quality_controlled":"1","main_file_link":[{"url":"https://www.sciencedirect.com/science/article/pii/S0022519387801005?via%3Dihub"}],"language":[{"iso":"eng"}],"doi":"10.1016/S0022-5193(87)80100-5","extern":"1","publist_id":"2727","publisher":"Elsevier","publication_status":"published","year":"1987","volume":126,"date_updated":"2022-02-04T12:36:32Z","date_created":"2018-12-11T12:04:28Z","author":[{"full_name":"Rouhani, Shahin","first_name":"Shahin","last_name":"Rouhani"},{"orcid":"0000-0002-8548-5240","id":"4880FE40-F248-11E8-B48F-1D18A9856A87","last_name":"Barton","first_name":"Nicholas H","full_name":"Barton, Nicholas H"}]},{"doi":"10.1016/0020-0190(87)90120-7","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://www.sciencedirect.com/science/article/pii/0020019087901207?via%3Dihub"}],"quality_controlled":"1","publication_identifier":{"eissn":["1872-6119"],"issn":["0020-0190"]},"month":"04","author":[{"full_name":"Edelsbrunner, Herbert","id":"3FB178DA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-9823-6833","first_name":"Herbert","last_name":"Edelsbrunner"},{"last_name":"Overmars","first_name":"Mark","full_name":"Overmars, Mark"}],"volume":24,"date_created":"2018-12-11T12:06:57Z","date_updated":"2022-02-03T13:29:17Z","year":"1987","publisher":"Elsevier","publication_status":"published","publist_id":"2023","extern":"1","date_published":"1987-04-06T00:00:00Z","citation":{"ama":"Edelsbrunner H, Overmars M.

In this way, efficient solutions were obtained for the windowing problem that asks for those line segments in a planar set that lie in given window (range) and the moving problem that asks for the first line segment that comes into the window when moving the window in some direction. In this paper we show that also the zooming problem, which asks for the first line segment that comes into the window when we enlarge it, can be solved efficiently. This is done by repeatedly performing range queries with ranges of varying sizes. The obtained structure is dynamic and yields a query time of O(log2n) and an insertion and deletion time of O(log2n), where n is the number of line segments in the set. The amount of storage required is O(n log n). It is also shown that the technique of repeated range search can be used to solve several other problems efficiently.","lang":"eng"}],"type":"journal_article"},{"type":"journal_article","abstract":[{"lang":"eng","text":"This paper investigates the existence of linear space data structures for range searching.

We show that the substitution of selectively favorable mutations often proceeds more rapidly for X- or Y-linked loci than for the autosomes, provided that mutations are recessive or partially recessive on the average. Selection acting on a quantitative character is expected to result in similar long-term rates of gene substitution for X-linked and autosomal loci, unless there is strong directional dominance. Short-term responses to such selection often preferentially fix alleles at autosomal loci. The fixation of slightly deleterious alleles by random drift and the stochastic turnover of alleles at loci controlling quantitative characters under stabilizing selection usually proceed somewhat more slowly at sex-linked loci. In contrast, the fixation of underdominant chromosomal rearrangements by random genetic drift is faster with sex linkage. Sex-specific selection may also differentially favor the fixation of sex-linked rearrangements. These results are discussed in relation to genetic and cytological data on species differences. We show that the frequently disproportionate effects of the sex chromosomes on interspecific inviability or sterility are consistent with the hypothesis that the gene differences concerned involve recessive or partially recessive alleles fixed by selection. Haldane's rule is readily interpreted in this light. There is little evidence for strong effects of the sex chromosomes on quantitative characters in interspecific crosses, in accordance with our theoretical results. Thus, the evolution of reproductive isolation may not be the byproduct of selective change in additively inherited, polygenic traits. Rather, it may be due mainly to the fixation of favorable mutations whose effects on fitness reflect locus-specific effects on the phenotype. These mutations behave as major genes in the sense of contributing the bulk of the genetic variance in the characters that they control during the course of the mutations' substitution. The data on the genetics of short-term responses to selection in Drosophila are hard to interpret, but, in accordance with theory, these responses do not usually seem to involve the X chromosome disproportionately. In some groups, there is evidence for a disproportionate role of the sex chromosomes in chromosomal changes, but others show no clear pattern. Factors that may distort the expectations of the simple models of chromosomal evolution are discussed."}],"type":"journal_article","oa_version":"None","user_id":"ea97e931-d5af-11eb-85d4-e6957dddbf17","_id":"3659","intvolume":" 130","title":"The relative rates of evolution of sex chromosomes and autosomes","status":"public"},{"issue":"2","abstract":[{"text":"The maintenance of polygenic variability by a balance between mutation and stabilizing selection has been analysed using two approximations: the ‘Gaussian’ and the ‘house of cards’. These lead to qualitatively different relationships between the equilibrium genetic variance and the parameters describing selection and mutation. Here we generalize these approximations to describe the dynamics of genetic means and variances under arbitrary patterns of selection and mutation. We incorporate genetic drift into the same mathematical framework.\r\nThe effects of frequency-independent selection and genetic drift can be determined from the gradient of log mean fitness and a covariance matrix that depends on genotype frequencies. These equations describe an ‘adaptive landscape’, with a natural metric of genetic distance set by the covariance matrix. From this representation we can change coordinates to derive equations describing the dynamics of an additive polygenic character in terms of the moments (means, variances, …) of allelic effects at individual loci. Only under certain simplifying conditions, such as those derived from the Gaussian and house-of-cards approximations, do these general recursions lead to tractable equations for the first few phenotypic moments. The alternative approximations differ in the constraints they impose on the distributions of allelic effects at individual loci. The Gaussian-based prediction that evolution of the phenotypic mean does not change the genetic variance is shown to be a consequence of the assumption that the allelic distributions are never skewed. We present both analytical and numerical results delimiting the parameter values consistent with our approximations.","lang":"eng"}],"type":"journal_article","oa_version":"None","intvolume":" 49","status":"public","title":"Adaptive landscapes, genetic distance, and the evolution of quantitative characters","_id":"3660","user_id":"ea97e931-d5af-11eb-85d4-e6957dddbf17","article_processing_charge":"No","day":"01","scopus_import":"1","date_published":"1987-04-01T00:00:00Z","page":"157 - 174","article_type":"original","citation":{"ama":"Barton NH, Turelli M.

Right from the beginning, it was obvious that strong connections of various kinds exist to questions studied in the considerably older field of combinatorial geometry. For example, the combinatorial structure of a geometric problem usually decides which algorithmic method solves the problem most efficiently. Furthermore, the analysis of an algorithm often requires a great deal of combinatorial knowledge. As it turns out, however, the connection between the two research areas commonly referred to as computa tional geometry and combinatorial geometry is not as lop-sided as it appears. Indeed, the interest in computational issues in geometry gives a new and con structive direction to the combinatorial study of geometry. It is the intention of this book to demonstrate that computational and com binatorial investigations in geometry are doomed to profit from each other. To reach this goal, I designed this book to consist of three parts, acorn binatorial part, a computational part, and one that presents applications of the results of the first two parts. The choice of the topics covered in this book was guided by my attempt to describe the most fundamental algorithms in computational geometry that have an interesting combinatorial structure. In this early stage geometric transforms played an important role as they reveal connections between seemingly unrelated problems and thus help to structure the field."}],"publist_id":"2257","extern":"1","type":"book","place":"Berlin ; Heidelberg","alternative_title":["EATCS monographs on theoretical computer science"],"author":[{"full_name":"Edelsbrunner, Herbert","orcid":"0000-0002-9823-6833","id":"3FB178DA-F248-11E8-B48F-1D18A9856A87","last_name":"Edelsbrunner","first_name":"Herbert"}],"related_material":{"link":[{"url":"https://koha.app.ist.ac.at/cgi-bin/koha/opac-detail.pl?biblionumber=4096","relation":"other","description":"available via catalog IST BookList"}]},"date_created":"2018-12-11T12:05:47Z","date_updated":"2021-12-22T12:59:57Z","volume":10,"oa_version":"None","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","_id":"3900","year":"1987","title":"Algorithms in Combinatorial Geometry","publication_status":"published","status":"public","intvolume":" 10","publisher":"Springer"},{"quality_controlled":"1","main_file_link":[{"url":"https://ieeexplore.ieee.org/document/5009474"}],"language":[{"iso":"eng"}],"doi":"10.1109/TC.1987.5009474","month":"11","publication_identifier":{"issn":["0018-9340"],"eissn":["1557-9956"]},"publication_status":"published","publisher":"IEEE","acknowledgement":"We would like to thank two anonymous referees for their constructive criticism.
