text: When two populations which differ at many loci meet, the degree of introgression
of alleles across the boundary will depend on the selection acting on each locus
(s), the rate of recombination between adjacent loci (r), and the number of loci
involved (n). Simple scaling arguments suggest that the behavior of the system
should depend on the ratio of selection to recombination (θ = s/r), and on n.
This is borne out by mathematical analysis of two demes which exchange individuals
at a low rate; when selection is stronger than recombination (θ > 1), the effective
selection on each locus is comparable to the total selection over the whole genome
(s* ∼ ns). When selection is weaker than recombination (θ < 1), the effective
selection is much weaker, but is still stronger than the selection on each locus
alone (s* \sim sn20 for small θ). When n is very large, these two regimes are
separated by a sharp threshold at θ = 1. The results are extended to two taxa
which meet in a continuous habitat; the effective selection pressure, which determines
the width of the hybrid zone, behaves in the same way as for the simpler case
above. Even when selection is weak compared to recombination, multilocus clines
have a sharp step at their center, flanked by tails of introgression in which
the alleles behave independently of each other. The set of clines acts as a barrier
to gene flow, and it is shown that the barrier is strongest when selection is
spread over many loci. The implications of the results for divergence and speciation
are discussed.

text: "Let S denote a set of n points in the plane such that each point p has assigned
a positive weight w(p) which expresses its capability to influence its neighbourhood.
In this sense, the weighted distance of an arbitrary point x from p is given by
de(x,p)/w(p) where de denotes the Euclidean distance function. The weighted Voronoi
diagram for S is a subdivision of the plane such that each point p in S is associated
with a region consisting of all points x in the plane for which p is a weighted
nearest point of S.\r\n\r\nAn algorithm which constructs the weighted Voronoi
diagram for S in O(n2) time is outlined in this paper. The method is optimal as
the diagram can consist of Θ(n2) faces, edges and vertices.\r\n"

text: Rectangle intersections involving rectilinearly-oriented (hyper-) rectangles
in d-dimensional real space are examined from two points of view. First, a data
structure is developed which is efficient in time and space and allows us to report
all d-dimensional rectangles stored which intersect a d-dimensional query rectangle.
Second, in Part II, a slightly modified version of this new data structure is
applied to report all intersecting pairs of rectangles of a given set. This approach
yields a solution which is optimal in time and space for planar rectangles and
reasonable in higher dimensions.

text: A generalization of the convex hull of a finite set of points in the plane
is introduced and analyzed. This generalization leads to a family of straight-line
graphs, " \alpha -shapes," which seem to capture the intuitive notions of "fine
shape" and "crude shape" of point sets. It is shown that a-shapes are subgraphs
of the closest point or furthest point Delaunay triangulation. Relying on this
result an optimal O(n \log n) algorithm that constructs \alpha -shapes is developed.

text: The hybrid zone which forms when two partially incompatible populations meet
acts as a barrier to gene flow. We discuss electrophoretic and theoretical evidence
on the strength of such barriers. Hybrid zones generally involve considerable
electrophoretic divergence. The enzyme clines are consistent in position and width;
in some cases, they show consistently asymmetric patterns of introgression. This
consistency suggests that the clines are maintained primarily by the indirect
effects of selection at linked loci, rather than by the effect of each individual
locus on fitness. A cline at a single locus will present some barrier, regardless
of the selective mechanism which maintains it. However, unless the locus induces
virtually complete assortment or hybrid unfitness, the barrier will be weak. Spreading
the same selection over more clines gives a stronger barrier. If the clines are
staggered, this barrier is still unlikely to be significant; if they coincide,
and if selection is stronger than recombination, then the barrier will be very
strong; its strength and asymmetry will be consistent over different loci. Thus,
the taxonomic status of divergent populations cannot be inferred just from the
total amount of pre- or post-mating isolation; the number of genetic differences,
and the interactions between them are equally important in determining rates of
gene flow.

text: The dispersal rate of the grasshopper Podisma pedestris has been measured,
with the aim of interpreting the width of a chromosomal cline. 171 adults were
marked individually, and released within the cline. 169 movements were seen over
three subsequent scorings; the distribution of distances, after correction for
the loss of long distance dispersants, was close to a normal curve, but there
was an initial shift of ten metres, perhaps towards a better habitat. The linear
variance increased at about 214 m2 day- 1, which corresponds to a standard deviation
of 207 m gen- 1/2 over a 20 day life span. Statistical uncertainty in this estimate
can be expressed using a distribution-free maximum likelihood method, which gives
support limits of 186- 270 m gen- 1/2. However, the main errors come from extrapolating
from this experiment to the cline as a whole.

text: "An algorithm for the geometric problem of determining a line (called a stabbing
line) which intersects each ofn given line segments in the plane is presented.
As a matter of fact, the algorithm computes a description of all stabbing lines.
A purely geometric fact is proved which infers that this description requiresO(n)
space to be specified. Our algorithm computes it inO(n logn) time which is optimal
in the worst case.\r\nUsing the description of the stabbing lines, we are able
to decide inO(logn) time whether or not a specified line is a stabbing line. Finally,
the problem of maintaining the description of all stabbing lines while inserting
and deleting line segments is addressed."

cline which runs for 100 km across the Alpes Maritimes in south-eastern France.
An intensive study of the easternmost end of this cline shows that it is about
800 m wide; the cline is not smooth, containing substantial spikes in chromosome
frequency which might be due to sampling drift. Though the cline seems narrow,
it is wide compared with the dispersal rate of the insect; a selective force of
only 0.5% would be enough to maintain the cline. It is difficult to determine
the nature of this force, but some evidence comes from the position of the cline,
and from the presence of coincident clines at other loci. An estimate of the distribution
of Podisma has been made, and the cline seems to follow, for the most part, a
region of low population density, suggesting that it is maintained by hybrid unfitness.
However, in the one region where the cline is relatively free to move, the XY
race bulges forwards more than would be expected if hybrids are unfit. The observation
of severe inviability in crosses between the races, though it is not associated
with the chromosomal difference, also indicates that this cline is the result
of some sort of genetic incompatibility.

text: In 1979 Kirpatrick obtained a practically feasible algorithm for planar regionlocation
working in linear space and logarithmic time, provided the regions are bounded
by straight line segments. No algorithm requiring only linear space and log-polynomial
time was known, so far, for general planar regionlocation, i.e. for the case where
regions are bounded by curves more complicated than straight line segments. As
main result of this paper such an algorithm is presented.

text: Samples were taken from five sites in a transect across the hybrid zone between
two chromosomal races of the grasshopper Podisma pedestris. Crosses were set up
between insects from the same population, and between populations spanning the
zone, and the early viability of the offspring was measured. Hybrids between pure
populations had reduced viability, and the viability of insects from the middle
of the zone was still lower, showing that most (87 per cent) of the inviability
was due to the breakup of coadapated gene complexes. Although the total selection
acting was strong (log. fitness reduced by S25), it was spread over a region wider
than the dispersal range (350 m vs. 20 m). Hence, the selection on each locus
contributing towards the inviability is weak (3 per cent). Many (150) independent
chromosome segments act cumulatively to produce inviability at this stage in the
life history. The implications of these findings for models of divergence are
discussed.
