The island syndrome in plants on New Zealand's outlying islands: a review
New Zealand Journal of Botany, Volume 63, Issue 5, Page 2300-2324, December 2025.ABSTRACT The island syndrome is defined as a suite of predictable and consistent differences between island and mainland organisms. In seed plants, much of what we know about the island syndrome comes from work in the Southwest Pacific, which is comprised of the three main islands of New Zealand and ten surrounding archipelagos.

Molecular Ecology, Volume 34, Issue 23, December 2025.ABSTRACT Understanding the evolutionary processes underlying range‐wide genomic variation is critical to designing effective conservation and restoration strategies. Evaluating the influence of connectivity, demographic change and environmental adaptation for threatened species can be invaluable to proactive conservation of evolutionary potential.

The Evolution of Dioecy-Concluding Remarks
Annals of the Missouri Botanical Garden, 1984 Since the pioneer work of Darwin on the evolution of sexual systems in plants (Darwin, 1877a, 1877b) no sexual strategy in recent years has attracted as much attention as dioecy. First, a number of population genetic models were developed in the 1970s to trace the evolution of dioecy via different pathways (Lloyd, 1975, 1976, 1979; Ross, 1970, 1978 ...

Progress in the study of dioecy in Mexican cycad species and its implications for conservation
Plant Species Biology, Volume 40, Issue 6, Page 556-571, November 2025.Cycads are endangered dioecious plants of great ornamental value that have a long period of sexual maturity. Therefore, it is crucial to have methods for early sex determination that can help to develop effective strategies for their conservation. Abstract Dioecy is a system of sexual reproduction in plants, characterized by the spatial separation of ...

Plant Species Biology, Volume 40, Issue 6, Page 527-529, November 2025.Often regarded as “living fossils,” cycads are well known for retaining many ancestral traits, which makes them particularly fascinating to naturalists and scientists alike. Cycads provide insights into the functional and developmental processes underlying the origin and diversification of seed plants, and they may help clarify how they colonized the ...

Retrotransposon Proliferation Coincident with the Evolution of Dioecy in Asparagus
G3: Genes, Genomes, Genetics, 2016 Current phylogenetic sampling reveals that dioecy and an XY sex chromosome pair evolved once, or possibly twice, in the genus Asparagus. Although there appear to be some lineage-specific polyploidization events, the base chromosome number of 2n = 2× = 20
