Marine forests of the Mediterranean-Atlantic Cystoseira tamariscifolia complex show a southern Iberian genetic hotspot and no reproductive isolation in parapatry [PDF]
, 2018 Climate-driven range-shifts create evolutionary opportunities for allopatric divergence and subsequent contact, leading to genetic structuration and hybrid zones.

African Crop Science Journal, 2011 Fifty genotypes of lentil (Lens culnaris Medik) were evaluated under eight environments for seed yield and its associated traits. All the genotypes were grouped into seven clusters. The composition of various clusters variedfrom 2 to 12. Clustering pattern revealed the distribution of the genotypes belonging to the same origin in more than one cluster ...

Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance Hybridization can promote speciation, and examples of putative hybrid species have now been identified across the tree of life. However, we still know little about the conditions that are most conducive to hybrid speciation.

Genetic divergence in okra (Abelmoschus Esculentus L. Moench.) [PDF]
Electronic Journal of Plant Breeding, 2013 Genetic divergence was studied among 25 okra germplasm lines using Mahalanobis D2 analysis. Analysis of variances for dispersion indicated significant differences among the genotypes and they were grouped into four clusters. The cluster I consisted of 22

Cirsium species show disparity in patterns of genetic variation at their range-edge, despite similar patterns of reproduction and isolation [PDF]
, 2003 Genetic variation was assessed across the UK geographical range of Cirsium acaule and Cirsium heterophyllum. A decline in genetic diversity and increase in population divergence approaching the range edge of these species was predicted based on parallel ...

Genetic divergence studies in safflower (Carthamus tinctorius L.) germplasm lines [PDF]
Electronic Journal of Plant Breeding, 2013 Ninety safflower genotypes representing diverse geographic regions were studied for genetic divergence using Mahalanobis D2 static. The genotypes were grouped into 12 clusters. Seed yield contributed maximum to the total divergence.

Genetic and morphological divergence in the warm-water planktonic foraminifera genus Globigerinoides
PLoS ONE, 2019 The planktonic foraminifera genus Globigerinoides provides a prime example of a species-rich genus in which genetic and morphological divergence are uncorrelated.

GENETIC DIVERGENCE IN DEEPWATER RICE GENOTYPES [PDF]
Journal of Central European Agriculture, 2006 The nature and the magnitude of genetic divergence was estimated in 35 deepwater rice genotypes using Mahalonobis’s D2 – statistics. The genotypes were grouped onto 10 clusters showing fair degree of relationship between geographic distribution and ...

Patterns of reproductive isolation in toads.
PLoS ONE, 2008 Understanding the general features of speciation is an important goal in evolutionary biology, and despite significant progress, several unresolved questions remain.
