Fossils improve phylogenetic analyses of morphological characters. [PDF]

open access: yesProc Biol Sci, 2021
Fossils provide our only direct window into evolutionary events in the distant past. Incorporating them into phylogenetic hypotheses of living clades can help elucidate macroevolutionary patterns and processes, such as ancestral states and ...

New Phylogenetic Markov Models for Inapplicable Morphological Characters. [PDF]

open access: yesSyst Biol, 2023
This paper proposes new Markov models for phylogenetic inference with anatomically dependent (inapplicable) morphological characters. The proposed models can explicitly model an anatomical dependency in which one or several characters are allowed to ...

Stochastic Mapping of Morphological Characters [PDF]

open access: yesSystematic Biology, 2003
Many questions in evolutionary biology are best addressed by comparing traits in different species. Often such studies involve mapping characters on phylogenetic trees. Mapping characters on trees allows the nature, number, and timing of the transformations to be identified.

Morphological features of mice of the genus Sylvaemus under conditions of syntopy in the eastern forest steppe of Ukraine

open access: yesTheriologia Ukrainica, 2023
The opinion regarding morphological changes in S. sylvaticus depending on being in syntopy with the competing sibling species S. tauricus is ambiguous. Most authors claim that allotopic and syntopic populations do not differ.
