Fig. 2 in Scandinavian Oncophorus (Bryopsida, Oncophoraceae): species, cryptic species, and intraspecific variation
Fig. 2. The positions of three leaves from each of 18 molecularly identified specimens of O. elongatus, 14 of O. wahlenbergii A and C, and 3 of O. wahlenbergii B (cf. Fig. 1) (A), and of 10 specimens of O. virens and 10 of O. integerrimus Hedenäs sp. nov. (B), along the first two axes in a PCA. The PCA is based on each leaf's length (LL), width (LW), and leaf lamina cell length, width, and length/width ratio in the apical (AL, AW, AR), middle (ML, MW, MR), and sheathing basal (BL, BW, BR) lamina. Cell measurements are the mean values of 20 cells per position in each leaf. Axes 1 (x) and 2 (y) explain 30.69% and 25.24% of the variation in A, and 32.56% and 22.01% of the variation in B. Insert diagrams A:1 and B:1 depict explanatory factors in the plane of these two axes.

Fig. 1. NeighborNet split network for the 104 in Scandinavian Oncophorus (Bryopsida, Oncophoraceae): species, cryptic species, and intraspecific variation
Fig. 1. NeighborNet split network for the 104 specimens studied, based on ITS (A) and the chloroplast markers trnG and rps4 (B): Oncophorus crispifolius (O.c., 2 specimens), O. dendrophilus (O.d., 2), O. elongatus (24), O. rauei (O.r., 2), O. virens (22), O. wahlenbergii (22), O. integerrimus Hedenäs sp. nov. (26), and outgroup (light grey boxes: C.s. = Cynodontium strumiferum, 2; R.f. = Rhabdoweisia fugax, 2). Haplotype networks based on all samples of O. elongatus, O. virens, O. wahlenbergii, and O. integerrimus Hedenäs sp. nov. are shown distal to 'branches' identified in the split network to show the full resolution among haplotypes. Circle size in the haplotype networks is proportional to the number of sampled populations of a certain haplotype, and sample numbers are explained in Table 1. Circles connected by a line differ in a single mutational difference; black dots indicate 'missing' haplotypes. Jacknife support values of 75–94.99 and 95–100 are indicated by transverse grey and black lines, respectively.

Data from: Limited intraspecific variation in drought resistance along a pronounced tropical rainfall gradient
<p>Assessing within-species variation in response to drought is crucial for predicting species responses to climate change and informing restoration and conservation efforts, yet experimental data are lacking for the vast majority of tropical tree species. We assessed intraspecific variation in response to water availability across a strong rainfall gradient for 16 tropical tree species using reciprocal transplant and common garden field experiments, along with measurements of gene flow and key functional traits linked to drought resistance.</p>
