Frogs on a Plain: Spatial Ecology of Crawfish Frogs in Arkansas’ Remnant Prairies
Bibliographic record
Abstract
The prairie peninsula was an expansive and important habitat that covered much of midwestern North America, from Canada to Arkansas, USA. But the prairie peninsula has shrunk by as much as 99% since 1830, and therefore, land acquisition and public/private partnerships are critical for the preservation of prairies and their associated species. In Arkansas, one species that benefits from protected prairies is the Crawfish Frog (Lithobates areolatus), which is currently declining precipitously throughout its range. Adult Crawfish Frogs spend most of their lives in terrestrial refugia (crayfish burrows), making them highly vulnerable to habitat loss and fragmentation, thereby creating a need to understand their movement and burrow site selection within extant prairie habitats. To that end, we implanted VHF transmitters into adult male Crawfish Frogs (n=74) from four breeding wetlands and radio-located them during spring 2021- 2023 at protected prairie sites in Arkansas. We also investigated what microhabitat factors frogs may be selecting for when choosing primary burrows (i.e. vegetation composition, vegetation density, and elevation). On average, Crawfish Frogs moved 164 m (Range 19 - 396 m) from breeding wetlands to primary burrows, which is half the distance recorded for the species at the southern and northern extents of the range. The differences in migration distance in Arkansas may be influenced by climate, habitat quality and composition, or site management history. Additionally, although there were differences in vegetation composition between sites, there was no evidence that vegetation composition or structure influenced primary burrow site selection within open canopy prairie sites. Overall, this study suggests that Crawfish Frogs in Arkansas may require less upland habitat around breeding wetlands than in other parts of their range. My data suggests that a minimum upland buffer size of 358 m around breeding wetlands may be needed to maintain a population of Crawfish Frogs in Arkansas. Additionally, the conservation value of protected prairies without nearby fishless breeding wetlands could be enhanced by wetland creation or restoration. This study has important management implications for the conservation of this declining species.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
