Endless Forms: Species and Speciation
suit in faster evolution of reproductive isolation than generally occurs between
allopatric populations. Thus, the more direct effects of selection on the probability
of mating should mean that when it occurs, sympatric spe- ciation proceeds more

I Introduction In this chapter. first some key ideas and notions relevant to
allopatric and para- patric speciation are outlined hriefly and then mathematical
models that descrihe these processes are discussed. The logic hehind these
scenarios of ...

Primate Conservation Biology
Genetic isolation can arise for three reasons (Ridley 1996): because a
geographical barrier, such as a river or desert, intrudes between the two
populations (allopatric speciation); because gene flow is reduced by socio-
demographic structure ...

Evolutionary processes and theory
allopatric speciation may occur. On the other hand, increasing evidence supports
assumptions invoked in models of non-allopatric speciation. We also contrast
and evaluate the evidential foundation of allopatric speciation with that of ...

Progress and Prospects in Evolutionary Biology : The ...
Ehrman (1965) studied pairs of semispecies of D. paulistorum using strains
collected where the taxa are sympatric and where they are allopatric. Table 7-3
illustrates her results. The figures given here are the isolation index, calculated
as the ...

Cichlid Fishes: Behaviour, Ecology and Evolution
The debate on allopatric v. sympatric speciation continues, however, as does that
on the related, and perhaps more semantic argument about extra- v.
intralacustrine speciation, especially with regard to the species flocks of Lakes
Victoria, ...

Do Species Exist: Principles of Taxonomic Classification
The allopatric paradigm is nothing but the putting-into-words of an ad hoc
concept (Tautz, 2009). If allopatrically separated populations become different,
then selection has no “interest” in erecting prezygotic crossing barriers because
the ...

Phylogeny, Ecology, and Behavior: A Research Program in ...
At the coarsest level there are two categories of models, those involving the
physical disruption of gene flow by geographical isolation (allopatric modes), and
those which do not require isolation for speciation to occur (nonallopatric modes).

The females tested were from a red allopatric population (Clearbrook), a black
allopatric population (Humptulips Pond), and a black population immediately
upstream from a hybrid zone (this population and the hybrid zone will be
discussed in ...

Molecular Evolution and Adaptive Radiation
In contrast, there is no special mechanism leading to allopatric speciation. Given
a geographic barrier, drift and the process of adaptation to local environments
will eventually and indirectly lead to reproductive isolation as a by-product of ...
