The invasion of Chinese tallow ( (L.) Small) is a serious threat to the endangered slash pine () flatwood ecosystem in the Gulf of Mexico Coastal Plain, United States. Prescribed fire in combination with vegetation management has been suggested as a preferred approach for mitigating Chinese tallow invasion and restoring this endangered ecosystem.

Article Synopsis
  • Modern forest management aims to balance social, economic, and ecological goals, with the impact of different management methods on forest ecosystems being a key consideration.
  • Two silvicultural systems studied (even and uneven aged) showed varying effects on vertebrate populations over two decades, with birds exhibiting significant changes in abundance, while small mammals and reptiles had more modest but generally positive responses.
  • Overall, the study highlights the importance of spatial and temporal scales in understanding how different management practices affect diverse wildlife groups, enabling better-informed conservation decisions.

We present predictor variables and R and Stan code for simulating and analyzing counts of Missouri Ozark herpetofauna in response to three forest management strategies. Our code performs four primary purposes: import predictor variables from spreadsheets; simulate synthetic response variables based on imported predictor variables and user-supplied values for data-generating parameters; format synthetic data for export to Stan; and analyze synthetic data.

Recent studies have demonstrated substantial effects of environmental stress that vary among clones. Exposure to ultraviolet radiation (UV) is an important abiotic stressor that is highly variable in aquatic ecosystems due to diel and seasonal variations in incident sunlight as well as to differences in the UV transparency of water among water bodies, the depth distribution of organisms, and the ability of organisms to detect and respond to UV. In contrast to the convention that all UV is damaging, evidence is accumulating for the beneficial effects of exposure to low levels of UV radiation.
