Hybridization and speciation
A perspective on the context and evolutionary significance of hybridization during speciation is offered, highlighting issues of current interest and debate and suggesting that the Dobzhansky–Muller model of hybrid incompatibilities requires a broader interpretation.
Integrative taxonomy: a multisource approach to exploring biodiversity.
A flexible procedure and stopping rule is presented that uses the information from different disciplines separately for integrative taxonomy, finding that rigor in species delimitation can be increased when several disciplines chosen for complementarity are used.
A Taxonomic Revision of the Palaearctic Members of the Ant Subgenus Lasius S. Str. (Hymenoptera, Formicidae)
A revision of the Palaearctic members of the ant subgenus Lasius s.str. is presented the fundamentals of which are application of Numeric Morphology-Based Alpha-Taxonomy (NUMOBAT), investigation of
A multidisciplinary approach reveals cryptic diversity in Western Palearctic Tetramorium ants (Hymenoptera: Formicidae).
It is concluded that the seven entities within the T. caespitum/impurum complex represent seven species, and neotypes are designated and redescribe the two species in terms of morphology and mtDNA.
A taxonomic revision of the Formica rufibarbis FABRICIUS, 1793 group (Hymeno- ptera: Formicidae)
The Palaearctic members of the Formica rufibarbis FABRICIUS, 1793 group were investigated by means of numeric morphology-based alpha-taxonomy (NUMOBAT). 496 nest samples comprising 1753 worker
Light at the end of the tunnel: Integrative taxonom y delimits cryptic species in the Tetramorium caespitum complex (Hymenoptera: Formicidae)
Species delimitation is fundamental for many biolog ical studies; its importance extends from regional faunistics over behavioral research to the reconstruction of evolut i nary history. However,
Evolution of male morphology in the ant genus Cardiocondyla.
The evolution of queen number from ancestral polygyny to derived monogyny appears to be associated with a switch in the behavior of ergatoid males from fighting to mutual tolerance.
The Evolution of Invasiveness in Garden Ants
The results challenge the notion that supercolonial organization is an inevitable consequence of low genetic variation for chemical recognition cues in small invasive founder populations and infer that low variation and limited volatility in cuticular hydrocarbon profiles already existed in the native range in combination with low dispersal and a highly viscous population structure.
