FIGURE 2 in Biogeographical affinity shapes relationships between ecological and phylogenetic mammal diversity and associations with their environmental correlates in the Americas
FIGURE 2. Spatial patterns of variation in the phylogenetic diversity (AvPD) of different mammal groups over the Americas. Maps are in Mollweide equal-area projection. Dash lines on each map indicate the location of the tropics in the Northern and Southern Hemispheres.
FIGURE 3 in Biogeographical affinity shapes relationships between ecological and phylogenetic mammal diversity and associations with their environmental correlates in the Americas
FIGURE 3. Non-stationary associations between ecological diversity (ED) and phylogenetic diversity (AvPD). The maps show the local beta coefficients (b) for AvPD as predictor of ED, obtained from the full model, i.e., including all environmental predictors and species richness (TR), after application of geographically weighted regression separately on data for each mammal group. Following (Matthews & Yang 2012) non-significant values (p> 0.05) are excluded from the maps to optimize the visualization of patterns. Regions of (+) and negative (-) associations are indicated. Maps are in Mollweide equal-area projection. Dash lines on each map indicate the location of the tropics in the Northern and Southern Hemispheres.
Telomere length correlates with physiological and behavioural responses of a long-lived seabird to an ecologically-relevant challenge
<p>Determinants of individual variation in reallocation of limited resources towards self-maintenance versus reproduction are not well known. We tested the hypothesis that individual heterogeneity in long-term "somatic state" a) explains variation in endocrine and behavioural responses to environmental challenges, and b) is associated with variation in strategies for allocating to self-maintenance versus reproduction. We used relative telomere length as an indicator of somatic state and experimentally generated an abrupt short-term reduction of food availability (withdrawal of food supplementation) for free-living seabirds (Black-legged kittiwakes, Rissa tridactyla). Incubating male kittiwakes responded to withdrawal by increasing circulating corticosterone and losing more weight compared to continuously supplemented controls. Males with longer telomeres increased time in directed travel regardless of treatment, while experiencing smaller increases in corticosterone. Males with longer telomeres fledged more chicks in the control group and tended to be more likely to return regardless of treatment. This study supports the hypothesis that somatic state can explain variation in short-term physiological and behavioural responses to challenges, and longer-term consequences for fitness. Male kittiwakes with longer telomeres appear to have prioritized investment in self over investment in offspring under challenging conditions.</p>

Data from: Ecological correlates of ghost lineages in ruminants
Integration between phylogenetic systematics and paleontological data has proved to be an effective method for identifying periods that lack fossil evidence in the evolutionary history of clades. In this study we aim to analyze whether there is any correlation between various ecomorphological variables and the duration of these underrepresented portions of lineages, which we call ghost lineages for simplicity, in ruminants. Analyses within phylogenetic (Generalized Estimating Equations) and non-phylogenetic (ANOVAs and Pearson correlations) frameworks were performed on the whole phylogeny of this suborder of Cetartiodactyla (Mammalia). This is the first time ghost lineages are focused in this way. To test the robustness of our data, we compared the magnitude of ghost lineages among different continents and among phylogenies pruned at different ages (4, 8, 12, 16, and 20 Ma). Differences in mean ghost lineage were not significantly related to either geographic or temporal factors. Our results indicate that the proportion of the known fossil record in ruminants appears to be influenced by the preservation potential of the bone remains in different environments. Furthermore, large geographical ranges of species increase the likelihood of preservation.
Figure 12 in Alpine-Himalayan orogeny drove correlated morphological, molecular, and ecological diversification in the Persian dwarf snake (Squamata: Serpentes: Eirenis persicus)
Figure 12. Response curve of the maximum entropy (Maxent) model. A, response curves of the precipitation of the coldest quarter, used to calculate the western operational taxonomic unit (OTU) Maxent model of the Eirenis persicus species group; B, response curves of the minimum temperature of the coldest month (°C), used to calculate the nigrofasciatus and eastern OTU Maxent model of the E. persicus species group. The logistic prediction values changed as each environmental variable was varied one by one whilst keeping all other environmental variables at their average sample value. In (A), boxplots represent the precipitation of the coldest quarter in the habitat of E. persicus specimens in southwestern Iran (SW-IR), Turkey and western Iran (TK, W-IR), and northern Iran (N-IR); in (B), boxplots represent the minimum temperature of the coldest month (°C) in the habitat of E. persicus specimens of the nigrofasciatus OTU (nig), eastern Iran and Turkmenistan sub-OTU (E-IR, TM), north-eastern Pakistan sub-OTU (NE-PK), and specimens referred to Eirenis mcmahoni (mc).
