Fig. 6 in A multisource solution for a complex problem in biodiversity research: Description of the cryptic ant species Tetramorium alpestre sp.n. (Hymenoptera: Formicidae)

Fig. 6. Graphical method following Evanno et al. (2005) to detect the number K* of clusters that best fit the data, using 133 SNPs from the 67 haplotypes of 1113 bp of cox1 of Tetramorium caespitum, ambiguous nests (denoted by "?" in Fig. 5; see Section 5.4 for details), T. alpestre sp.n. (=T. sp. A), T. sp. B and T. impurum. (A) Mean L(K) over 20 runs for each K value; vertical bars indicate 1 standard deviation. (B) Delta K; the value of K with the highest value of the delta K distribution, i.e., 5, is K*. Note that delta K is not plotted for K = 1, because the calculation of delta K requires values of L(K − 1).

Fig. 7 in A multisource solution for a complex problem in biodiversity research: Description of the cryptic ant species Tetramorium alpestre sp.n. (Hymenoptera: Formicidae)

Fig. 7. Estimated structure in the mitochondrial DNA data of Tetramorium caespitum, ambiguous nests (denoted by "?" in Fig. 5; see Section 5.4. for details), T. alpestre sp.n. (=T. sp. A), T. sp. B and T. impurum, using 133 SNPs from the 67 haplotypes of 1113 bp of cox1, and K = 5, identified as the number of clusters that best fit the data (Fig. 6). Each haplotype is represented by a vertical bar which is partitioned into up to K shaded segments that represent the haplotype's estimated membership fractions in K clusters. Haplotypes are numbered as in Table 1.

Fig. 1 in A multisource solution for a complex problem in biodiversity research: Description of the cryptic ant species Tetramorium alpestre sp.n. (Hymenoptera: Formicidae)

Fig. 1. (A–C) Definition of morphometric characters: (A) posterior part of mesosoma in lateral view; the sum of the angles α, β, γ, δ, ε is not necessarily 360◦ because these are angles in a three-dimensional tetrahedron described by SPST, PLSP, MPPL, MPST, MPSP, and PLST; (B) petiolar node in lateral view; (C) mesosoma in lateral view. For definition of morphometric characters see Section 3.4.

Fig. 3 in A multisource solution for a complex problem in biodiversity research: Description of the cryptic ant species Tetramorium alpestre sp.n. (Hymenoptera: Formicidae)

Fig. 3. (A–F) Lateral (A, C, E; right side depicted) and dorsocaudal (B, D, F) view of male genitalia in (A and B) Tetramorium alpestre sp.n. (=T. sp. A.), (C and D) T. impurum and (E and F) T. caespitum et sp. B. The dorsocaudal viewing position is indicated by the arrow in (A). The scale bar equals 1 mm. Pilosity and pubescence omitted.

Fig. 4 in A multisource solution for a complex problem in biodiversity research: Description of the cryptic ant species Tetramorium alpestre sp.n. (Hymenoptera: Formicidae)

Fig. 4. Altitudinal and latitudinal distribution of Tetramorium alpestre sp.n. (=T. sp. A), T. caespitum et sp. B and T. impurum; see Section 5.4. for details concerning ambiguous nests #260 and #261.

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).
