Phylotranscriptomic analyses reveal the reticulate evolution in Dennstaedtiaceae

Journal of Systematics and Evolution
Dennstaedtiaceae, a heterogeneous family of ferns with 11 genera and about 270 species, has a global distribution. While substantial progress has been made in elucidating the intergeneric relationships within Dennstaedtiaceae, certain nodes, particularly

Reconstructing reticulate evolution in species

Proceedings of the eighth annual international conference on Computational molecular biology - RECOMB '04, 2004
We present new methods for reconstructing reticulate evolution of species due to events such as horizontal transfer or hybrid speciation; both methods are based upon extensions of Wayne Maddison's approach in his seminal 1997 paper. Our first method is a polynomial time algorithm for constructing phylogenetic networks from two gene trees contained ...

Examination of Reticulate Evolution Involving Haageocereus and Espostoa

Haseltonia. Yearbook of the Cactus and Succulent Society of America, 2021
: Intergeneric hybridization is not rare in Cactaceae, even between genera with very different pollination syndromes: thus, it appears that geographic barriers are more important than intrinsic reproductive barriers in this group.

Target enrichment data reveal rapid divergence with reticulate evolution of Maianthemum (Asparagaceae: Convallarioideae) in the Himalayan‐Hengduan Mountains and eastern Asia

Journal of Systematics and Evolution
Understanding plant diversity and the phylogenetic divergences in the Northern Hemisphere is essential for in‐depth evolutionary studies and conservation efforts.

Dissecting natural hybridisation in longhorned beetles through an integrative approach: Further proof of reticulate evolution in Dorcadionini (Cerambycidae, Lamiinae)

Zoologica Scripta
This work demonstrates for the first time using molecular markers alongside chromosomes and the intermediate phenotype that a specimen of Dorcadion is an accidental first‐generation hybrid.

Complex reticulate evolution of speckled brush‐furred rats (Lophuromys) in the Ethiopian centre of endemism

Molecular Ecology, 2021
The Ethiopian highlands represent a remarkable biodiversity ‘hot spot’ with a very high number of endemic species, even among vertebrates. Ethiopian representatives of a species complex of speckled brush‐furred rats (Lophuromys flavopunctatus sensu lato)

Phylogenomic insights into species relationships, reticulate evolution, and biogeographic diversification of the ginseng genus Panax (Araliaceae), with an emphasis on the diversification in the Himalayan‐Hengduan Mountains

Journal of Systematics and Evolution
Panax (Araliaceae) is a small genus containing several well known medicinally important species. It has a disjunct distribution between Eastern Asia and Eastern North America, with most species from eastern Asia, especially the Himalayan‐Hengduan ...

Reticulate Evolution in Machaeranthera (Asteraceae)

Systematic Botany, 1997
Previous analyses of chloroplast DNA restriction site data from Machaeranthera and related genera support many relationships that are incongruent with morphological and cytological data. To find explanations for these disagreements, sequence data from the internal transcribed spacers (ITS) of nuclear rDNA were obtained from the same genera and species ...

Convergent evolution of reticulate scales

Journal of Experimental Zoology, 1985
AbstractStructural proteins of scales with various morphologies were compared. Ventral reticulate scales have soluble proteins that differ from both dorsal reticulate scales and scutellate scales. Ventral reticulate scale proteins are more like those in reptilian scales, whereas both dorsal type scales have proteins of the ϕ‐keratin family found in ...

Divergence and Reticulation in Cultural Evolution

SSRN Electronic Journal, 2019
In a recent review of articles in computational criticism Franco Moretti and Oleg Sobchuk bring up the issue of tree-like (dendriform) vs. reticular phylogenies in biology and pose the question for the form taken by the evolution of cultural objects: How is cultural information transmitted, vertically (leading to trees) or horizontally (yielding webs)?
