Bite‐DNA Shows Substantial Browsing on Willows (Salix spp.) by North American Bison in Yellowstone National Park

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Riparian willows in Yellowstone National Park are shaped by ungulate browsing, but species‐specific contributions remain unclear. Using bite‐DNA metabarcoding of browsed willow twigs across six northern range sites, we found that American bison were the most frequent browsers, exceeding elk and often mule deer.

Contrasted patterns of evolution of the LINE-1 retrotransposon in perissodactyls: the history of a LINE-1 extinction

Mobile DNA, 2018
Background LINE-1 (L1) is the dominant autonomously replicating non-LTR retrotransposon in mammals. Although our knowledge of L1 evolution across the tree of life has considerably improved in recent years, what we know of L1 evolution in mammals is ...

Evolutionary affinities of the order perissodactyla and the phylogenetic status of the superordinal taxa ungulata and altungulata. Molecular Phylogenetics and Evolution

, 1997
Contrary to morphological claims, molecular data indicate that the order Perissodactyla (e.g., horses, rhinoceroses, and tapirs) is neither part of the superordinal taxon Paenungulata (Sirenia, Proboscidea, and Hyracoidea) nor an immediate outgroup of ...

The role of species interactions in shaping the geographic pattern of ungulate abundance across African savannah

Scientific Reports
Macroecologists traditionally emphasized the role of environmental variables for predicting species distribution and abundance at large scale. While biotic factors have been increasingly recognized as important at macroecological scales, producing ...
