FIGURE 1 in A standardized and statistically defensible framework for quantitative morphological analyses in taxonomic studies
FIGURE 1. Results of the meta-analysis on taxonomic papers focused on amphibians (top) and reptiles (bottom) published in the journal ZooKeys from 2008–2020. The analysis evaluated whether body size corrections or statistical analyses were performed on morphological data.
Sex-specific genetic (co)variances of standard metabolic rate, body mass and locomotor activity in Drosophila melanogaster
<p>A longstanding focus in evolutionary physiology concerns the causes and consequences of variation in maintenance metabolism. Insight into this can be gained by estimating the sex-specific genetic architecture of maintenance metabolism alongside other, potentially correlated traits on which selection may also act, such as body mass and locomotor activity. This may reveal potential genetic constraints affecting the evolution of maintenance metabolism. Here, we used a half-sibling breeding design to quantify the sex-specific patterns of genetic (co)variance in standard metabolic rate (SMR), body mass, and daily locomotor activity in <i>Drosophila melanogaster</i>. There was detectable additive genetic variance for all traits in both sexes. As expected, SMR and body mass were strongly and positively correlated, with genetic allometry exponents (<i>b</i><sub>A</sub>±se) of 0.66±0.16 in females and 0.58±0.32 in males. There was a significant and positive genetic correlation between SMR and locomotor activity in males, suggesting that alleles that increase locomotion have pleiotropic effects on SMR. Sexual differences in the genetic architecture were driven in large part by a difference in genetic variance in locomotor activity between the sexes. Overall, genetic variation was mostly shared between males and females, setting the stage for a potential intralocus sexual conflict in the face of sexually antagonistic selection.</p>

FIG. 6. Standardized Precipitation Index for the 6 in A Long-term Study of Home Range of Coachella Fringe-Toed Lizards, Uma inornata
FIG. 6. Standardized Precipitation Index for the 6-mo interval that encompasses winter rainfall at Palm Springs during the course of the study. Rainfall intervals were standardized against all other November through April intervals since 1927/28. An index of 0 to -0.99 indicates mild drought, -1.00 to -1.49 moderate drought, -1.50 to -1.99 severe drought, and -2.00 to -3.00 extreme drought. Positive index values indicate wet years and horizontal lines designate severe drought-year and severe wet-year thresholds.
