SI Figure 1: Dispersion values (a boxplot using distance to centroids based on Bray Curtis distance matrix) of external and internal bacterial microbiome composition for different hosts. In a mixed linear model, microinvertebrates did not significantly impact dispersion (P=0.44), but microbiome type did (P=0.03). Pairwise contrasts show that while external microbiomes of P. murrayi and Tardigrada are more variable than their internal microbiomes, E. antarcticus external and internal microbiomes are equally variable. in External and internal microbiomes of Antarctic nematodes are distinct, but more similar to each other than the surrounding environment

Impact of infectious diseases on wild bovidae populations in Thailand: Insights from population modelling and disease dynamics
<p>The wildlife and livestock interface is vital for wildlife conservation and habitat management. Infectious diseases maintained by domestic species may impact threatened species such as Asian bovids, as they share natural resources and habitats. To predict the population impact of infectious diseases with different traits, we used stochastic mathematical models to simulate the population dynamics over 100 years for 100 times a model gaur (<em>Bos gaurus</em>) population with and without disease. We simulated repeated introductions from a reservoir, such as domestic cattle. We selected six bovine infectious diseases; anthrax, bovine tuberculosis, hemorrhagic septicaemia, lumpy skin disease, foot and mouth disease and brucellosis, all of which have caused outbreaks in wildlife populations. From a starting population of 300, the disease-free population increased by an average of 228% over 100 years. Brucellosis with frequency-dependent transmission showed the highest average population declines (-97%), with population extinction occurring 16% of the time. Foot and mouth disease with frequency-dependent transmission showed the lowest impact, with an average population increase of 200%. Overall, acute infections with very high or low fatality had the lowest impact, whereas chronic infections produced the greatest population decline. These results may help disease management and surveillance strategies support wildlife conservation.</p>

Figure 1 in Value and impacts of collecting vertebrate voucher specimens, with guidelines for ethical collection
Figure 1. Geographic distribution of Museum Victoria's non-marine Victorian vertebrate specimens. Each pixel represents the number of specimens collected within a 100 km2 grid (10 x 10 km square) from the earliest georeferenced specimen (collected in 1858) to 2012, spanning 154 years. Yellow, green, light blue, and dark blue pixels represent single (1), low (2 – 10), moderate (11 – 100), and high (> 100) numbers of specimens, respectively. White pixels represent areas with no specimens. Histograms represent the number of specimens by decade.
Figure 1 in A new theoretical approach for the study of monophyly of the Brachyura (Crustacea: Decapoda) and its impact on the Anomura
Figure 1. Synapomorphy "d" supports the inclusion of the Podotremata (P) in the Brachyura, while the use of less generalized synapomorphies (a, b) in the definition will result in the exclusion of the Podotremata from the Brachyura. Synapomorphies: a, female sexual opening on thoracic sternite 6; b, presence of sella turcica; c, paired spermatheca; d, intertagmal phragma fused with thoracic interosternite 8/7 (pers. obs.). Other abbreviations: H, Heterotremata; Th, Thoracotremata. Figure 2. Assumption 1: both the Brachyura (H + Th + P) and Podotremata (P) are monophyletic. Under assumption 1 it makes no sense to search for the "lower limit" of the Brachyura. Synapomorphies and abbreviations as in Fig. 1. Figure 3. Assumption 2: Brachyura (H + Th + P) monophyletic; Podotremata (P) not monophyletic. Under assumption 2 it becomes meaningful to search for the sister taxa of the Heterotremata + Thoracotremata clade. Synapomorphies and abbreviations as in Fig. 1. Figure 4. Assumption 3: Brachyura (H + Th + P) not monophyletic; Podotremata (P) monophyletic. Under assumption 3 searching for the "lower limit" of the Brachyura among the Podotremata makes no sense. Synapomorphies and abbreviations as in Fig. 1. Figure 5. Assumption 4: both Brachyura (H + Th + P) and Podotremata (P) not monophyletic. According to corollary 1 searching for the sister taxa of the Heterotremata + Thoracotremata clade and searching for the most basal branch of the brachyuran clade becomes truly relevant. Note that one set of the Podotremata is positioned as paraphyletic complex closely related to the Heterotremata + Thoracotremata clade (H-Th). Synapomorphies and abbreviations as in Fig. 1. Figure 6. Assumption 4; corollary 2. Searching for the most basal branch of the brachyuran clade ("the lower limit") among the Podotremata is completely meaningless. Note that none of the Podotremata (P) is closely related to the Heterotremata + Thoracotremata clade; all form a paraphyletic complex more closely related to some other group of decapods. Synapomorphies and abbreviations as in Fig. 1.
