Folding and unfolding phylogenetic trees and networks [PDF]
, 2015 Phylogenetic networks are rooted, labelled directed acyclic graphs which are commonly used to represent reticulate evolution. There is a close relationship between phylogenetic networks and multi-labelled trees (MUL-trees).

Acta Societatis Botanicorum Poloniae, 2014 Many species of liverworts (Hepaticae) are morphologically plastic to such an extent that their proper recognition may cause difficulties even for a specialist. Central European species of the genus Pellia are notorious in this respect.

Which phylogenetic networks are merely trees with additional arcs? [PDF]
, 2015 A binary phylogenetic network may or may not be obtainable from a tree by the addition of directed edges (arcs) between tree arcs. Here, we establish a precise and easily tested criterion (based on `2-SAT') that efficiently determines whether or not any ...

Limnephilid taxa revised by speciation traits: Rhadicoleptus, Isogamus, Melampophylax genera, Chaetopteryx rugulosa, Psilopteryx psorosa species groups, Drusus bolivari, Annitella kosciuszkii species complexes (Trichoptera: Limnephilidae) [PDF]
Opuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis, 2015 Speciation traits of paramere, paraproct and aedeagus were applied to find initial split criteria with fine structure analysis in order to prepare diverged trait matrices for delimiting phylogenetic incipient species of unsettled limnephilid taxa in the ...

Ultraviolet plumage reflectance distinguishes sibling bird species [PDF]
Proceedings of the National Academy of Sciences, 2004 Realistic studies of plumage color need to consider that many birds can see near-UV light, which normal humans cannot perceive. Although previous investigations have revealed that UV-based plumage reflectance is an important component of various intraspecific social signals, the contribution of UV signals to inter-specific divergence and ...

European Journal of Entomology, 2008 The sibling species H. yedoensis Takizawa coexists sympatrically and simultaneously with H. axyridis only on pine trees in Japan. To elucidate the mechanisms enabling coexistence of these two sympatric sibling species, a laboratory experiment was ...

Resource competition between sympatric sibling rotifer species [PDF]
Limnology and Oceanography, 2001 Mechanisms underlying competitive interactions are important in understanding the structure of planktonic communities, particularly the coexistence of similar species. Here we present experimental results of exploitative competition among three sympatric sibling species of the Brachionus plicatilis complex for two differently‐sized species of food ...
