FIG. 5. A in Testosterone and Corticosterone Profiles and Body Condition of Calling and Non-calling Lithobates grylio
FIG. 5. A linear regression of ambient call rates averaged over one minute and circulating T for individual males. Individual circulating T was positively correlated with the number of conspecific calls recorded during each respective evening of sampling (R2 ¼ 0.285; Ŷ ¼ i 3895.38þ31.08Xi; P, 0.01).
FIG. 7 in Testosterone and Corticosterone Profiles and Body Condition of Calling and Non-calling Lithobates grylio
FIG. 7. Linear regression of circulating CORT and glucose concentrations in calling and non-calling males shows the amount of glucose in circulation positively correlates with circulating CORT within non-calling males (R2 ¼ 0.665; Ŷ ¼ 31.447 þ 0.098X; P, 0.001). The regression i i line is only indicative of a relationship between CORT and glucose concentrations for non-calling males, as there was no significant relationship between CORT and glucose in calling males (R2 ¼ 0.149; P ¼ 0.305).
FIG. 2 in Testosterone and Corticosterone Profiles and Body Condition of Calling and Non-calling Lithobates grylio
FIG. 2. (A) A linear regression of SVL and body mass suggests a positive linear allometric relationship between the variables (R2 ¼ 0.21; Ŷ ¼ i 37.64þ1.26Xi; P ¼ 0.02). (B) A boxplot of the residuals from Figure 2A for the ethotypes indicates calling males have significantly higher body masses than what is predicted by the SVL and body mass regression line (t23 ¼ 5.599; P, 0.001). Box size is based on the range of data points falling between the 2nd and 3rd quartiles. Mean is represented by the filled circle and median by the bold line.
FIG. 1 in Testosterone and Corticosterone Profiles and Body Condition of Calling and Non-calling Lithobates grylio
FIG. 1. Boxplots illustrating average (A) body mass, (B) snout–vent length (SVL), and (C) body condition index (BCI ¼ mass/SVL) for calling (n ¼ 11) and non-calling (n ¼ 14) males. Calling males had significantly higher body masses (A; t23 ¼ 3.725; P ¼.001) and body condition indices (C; t23 ¼ 5.599; P, 0.001) than non-callers. SVL did not significantly differ (n.s.) between the two ethotypes (B; t23 ¼ 0.577; P ¼ 0.570). Box size is based on the range of data points falling between the 2nd and 3rd quartiles. Mean is represented by the filled circle and median by the bold line. Open circles denote potential outliers that were not omitted from statistical analysis.
FIG. 3 in Testosterone and Corticosterone Profiles and Body Condition of Calling and Non-calling Lithobates grylio
FIG. 3. (A) Average circulating T in calling (n ¼ 20) and non-calling males (n ¼ 16). The numbers on the bars indicate sample size. T was significantly higher in callers (t34 ¼ 2.987; P, 0.01). (B) Average circulating CORT in calling (n ¼ 19) and non-calling (n ¼ 17) males, where CORT was elevated in non-callers (t ¼ 2.153; P ¼ 0.0381). Box size is based on the range of data points falling between the 2nd and 3rd quartiles. Mean is represented by 36 the filled circle and median by the bold line. Open circles denote potential outliers that were not omitted from statistical analysis.
Data for: Chronic corticosterone deteriorates latrine and nesting behaviours in mice
<p><span>Self-care behaviours a</span><span>re actions</span><span> that help maintain good health and surroundings. For example, appropriate toileting, sleeping in the bed, and bathing and washing are among self-care behaviours in humans. Animals also perform similar self-care behaviours such as latrine, nesting, and self-grooming. Studies have shown that chronic stress disrupts nesting and self-grooming behaviours. However, the effect of chronic stress on latrine behaviour, preferential, repeated defecation at specific locations, has not yet been clarified. This study a</span><span>imed to investigate</span><span> t</span><span>he influence of </span><span>chronic corticosterone administration o</span><span>n </span><span>latrine and nesting behaviours in mice. The variation in defecation location was quantified as the degree of the latrine behaviour by using Shannon entropy. The nest quality was scored based on shape. The study showed that mice exposed to chronic corticosterone had scattered defecation sites and lower nest quality c</span><span>ompared to </span><span>the control group. Furthermore, results showed that more scattered defecation behaviour was associated with lower nest quality at an individual level. Additionally, the deterioration of these self-care behaviours was associated with depression-like behaviours </span><span>such as less open field activity and increased immobility time during the tail suspension test</span><span>.</span><span> These results suggest that chronic corticosterone deteriorates self-care behaviours such as latrine and nesting in mice. This dataset includes physiological and behavioural data of mice used in the present study.</span></p>
