Morphometric allometry, the effect of size on morphological variation, has been great interest for evolutionary biologist and is currently used in fields such as wildlife ecology to inform management conservation. We assessed American alligator (Alligator mississippiensis) static allometry across Greater Everglades ecosystem South Florida, United States using a robust dataset (~ 22 years) investigated effects sex, habitat, sampling area relationships. Regression models showed very strong evidence linear relationship between variables explaining equal or above 92% variation data. Most trait-size relationships (8 out 11 assessed) hyperallometry (positive allometry) with slope deviations from isometry 0.1 0.2 units while other three were isometric. Sampling area, type lesser extent sex influenced allometric coefficients (slope intercept) several relationships, likely result differing landscapes dynamic alterations sexual dimorphism. discuss our findings terms biology species well usefulness results context restoration conservation species. Finally, we provide recommendations when trait-length infer population nutritional-health condition demographics.

Body condition is used as an indicator of the degree body fat in animal but evidence its actual relationship with health diagnostics (e.g., blood parameters) usually lacking across species. In American alligators ( Alligator mississippiensis ), has been a performance metric within Greater Everglades ecosystem to provide insight on hydrological and landscape changes alligator populations. However, there no clear that spatial relate different conditions (low food intake vs sickness) whether this link can be made when relating values parameters. We assessed between 36 hematological biochemistry (blood) parameters four areas two physiographic regions (Everglades Big Cypress) (sample size = 120). found very strong weak linearity 7 (Big 19 (Everglades) relative factor index, from which cholesterol (38%) uric acid (41%) for former phosphorus (up 52%) 45%) latter (mean absolute error MAE 0.18 each) were predictors individually explain most variation. The best combination cholesterol, phosphorus, osmolality, total protein, albumin, alpha 2, beta, gamma globulins, corticosterone accounting 40% (37 ± 21%, 0.16) variation region. better predictability power models analyzed at smaller rather than larger scales showing potential habitat effect condition—blood relationship. Overall, poorer are likely dehydrated or have inadequate diet differences suggest these differ prey availability/quality.
