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 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.
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,
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.
Tetramorium tsushimae, a New Invasive Ant in North America
Combining molecular and morphological evidence, an invasive ant in Missouri and Illinois, USA, is identified as Tetramorium tsushimae Emery, 1925, a polygynous-polycalic species native to East Asia.
Specificity and transmission mosaic of ant nest-wall fungi
This work characterized ascomycete fungal associates cultured for nest architecture by the ant subgenera Dendrolasius and Chthonolasius and infer vertical transmission, in the latter case overlaid by horizontal transmission.
Stable N-isotope signatures of central European ants – assessing positions in a trophic gradient
This study provides a first application of stable isotope technology to estimate the role of plant-derived nutrients to the nitrogen budget of a larger range of central European ants and shows that N-isotope analysis is applicable across extended ecological and geographical gradients.
Turning one into five: Integrative taxonomy uncovers complex evolution of cryptic species in the harvester ant Messor "structor".
The successful solution of this particular problem illustrates the usefulness of the integrative approach to other systematic problems of comparable complexity and the importance of understanding evolution to drawing correct conclusions on species' attributes, including their ecology and biogeography.
Abandoning Aggression but Maintaining Self-Nonself Discrimination as a First Stage in Ant Supercolony Formation
It is shown that the single-queened Lasius austriacus lacks aggression between colonies and occasionally integrates workers across colonies but maintains high within-colony relatedness and self-nonself discrimination.
