Sentence examples for isolated sister from inspiring English sources

When populations are separated and isolated in glacial refugia for a sufficient period of time they may evolve pre- or post-zygotic reproductive barriers and become reproductively isolated sister taxa [4] [6].

Such a mode of diversification can be inferred from phylogenetic relationships and host distributions of extant parasite species, the critical observation being a fully sympatric community of reproductively isolated sister parasite lineages within a geographically unstructured host species [8], [9].

For speciation, the divergence of an ancestral population into two reproductively isolated sister taxa requires genetic differentiation of at least those loci involved in reproductive (sexual) functions [ 1].

This fits the pattern of schizo-endemic distribution of C. balearicum and C. repandum found by Thompson et al. [ 36], whereby a single wide ranging species is assumed to be progenitor to a narrow ranging isolated sister species.

(We note that a recent study provides strong evidence that S. bayanus var. bayanus and S. bayanus var. uvarum are genetically and ecologically isolated sister species from two distinct lineages (Libkind, Hittinger, et al., unpublished data).

While incomplete lineage sorting can often impede reciprocal monophyly between fully isolated sister species with large population sizes, it is much less likely to maintain shared haplotypes and, moreover, it is unlikely to maintain a geographic correlation in the distribution of shared haplotypes between species.

In this process two previously isolated sister-species hybridize and give offspring to a new and possibly better-adapted species [ 19].

Though isolated, the sisters were fearless.

A phylogenetic analysis based on the 12 protein-coding genes of all available taeniid mtDNAs confirmed the two T. taeniaeformis isolates as sister taxa (likely separate species) and early divergent members of the genus, as suggested previously by morphology.

The atmosphere of British neurology in the early 1960s, somewhat elitist and oddly isolated from its sister disciplines of psychiatry and psychology, was probably uncongenial to Sacks, with his wide-ranging interests and cosmopolitan background; rumour has it that influential London neurologists had corresponding misgivings about allowing Sacks to join their number.

As was the case last year Emilie Dionne has been isolated from her sisters.
