Fig. 2 in A multisource solution for a complex problem in biodiversity research: Description of the cryptic ant species Tetramorium alpestre sp.n. (Hymenoptera: Formicidae)

Fig. 2. Integration of morphology, ecology and molecular genetics at nest level for T. alpestre sp.n (=T. sp. A), T. caespitum et sp. B and T. impurum; each nest is represented by a thin vertical bar; bars of different methods with identical horizontal position refer to the same nest; all nests of which workers were analysed morphometrically are shown; nests exclusively analysed by molecular genetics are not shown; the four nests to the right are the ambiguous nests from which specimens were available for morphological analysis (#260, #261, #i548, #i613). First row: results of classification by DA using the optimal character combination of 14 characters (CL/CW, CS, dCV, FL/CS, ML/CS, MPSP/CS, MW/CS, PENL/CS, PEW/CS, PnHL/CS, PosSPu/CS, PreOc/CS, SLd/CS, TAS) selected from 33 morphometric worker characters and TAS (thermal niche); the bar of each nest is partitioned into shaded segments that represent the probabilities of its species membership as calculated by DA; nests of holotypes of T. alpestre and T. caespitum var. penninum and of neotypes of T. caespitum and T. impurum are indicated. Second row: species identity resulting from analysis of male genital morphology. Third row: species identity resulting from phylogenetic reconstruction using mtDNA gene cox1 (Fig. 5).
