“…Moreover, a high portion of the E. oridanus's habitat within ENP surface target of prescribed re was characterized by the marsh ecotype (42%; 65.7 km 2 ), which is the ecotype with the highest target FRI. Overall, the variability simulated in re regimes by our model among landscape patches within the E. oridanus's habitat may re ect an acceptable re management towards this ecological goal (Tallie et al, 2021).…”

“…oridanus's habitat, the simulated mean FRI was higher than the recommended target FRI, and even higher than the optimal range. However, differently from habitats inside ENP for which there's agreement in the scienti c literature on their dependance on certain FRIs (i.e., A. maritimus mirabilis's, A. troglodyta oridalis and S. acis bartrami's habitats), it seems that the effect of re management on E. oridanus's activity is confounded by other important factors such as vegetation type and conditions (Tallie et al, 2021). For this reason, the maximum score that the protection of E. oridanus's habitat contributed to the model (6 points) was slightly lower than the maximum score attainable for the protection of A. maritimus mirabilis's, A. troglodyta oridalis and S. acis bartrami's habitats (8 points).…”

Background Prescribed fire is an essential strategy employed by natural resource managers to serve ecological objectives of fire management. However, limited operational resources, environmental conditions, and competing goals result in a finite number of burn days, which need to be allocated towards maximizing the overall benefits attainable with fire management. We developed a decision-support framework and a burn prioritization model for wetlands and wildland-urban interfaces in Everglades National Park (Florida, USA). The model included criteria relative to the conservation of plant communities, the protection of endangered faunal species, the protection of human life, the protection of cultural, archeological, and recreational resources, and the control of invasive plant species. A geographic information system was used to integrate the multiple factors affecting fire management into a single spatially and temporally explicit management model, which provided a quantitative computations-alternative to decision making that is usually based on qualitative assessments. Results The model outputs were 50-meter grid maps showing prioritization scores for the pixels which are targets of prescribed fire. During the 50 years of simulated prescribed fires run for model validation, the mean burned surface corresponded to 716 ± 501 km2 y− 1. Mean fire return intervals, simulated for marshes, prairies, and pine rocklands were 9.9 ± 1.7, 7.3 ± 1.9, 4.0 ± 0.7 years, respectively. Mean fire return intervals, simulated within the A. maritimus mirabilis, A. troglodyta floridalis and S. acis bartrami butterflies, and E. floridanus critical habitats were 7.4 ± 1.5, 3.9 ± 0.2, 6.5 ± 2.9 years, respectively. Conclusions By performing fine-scale spatial computations, the model supported diverse fire regimes across the wetland landscape, based on spatial variability of ecosystem types and species habitats, while satisfying the need to protect human life, cultural heritage, and infrastructure. Employment of the burn prioritization model will allow the achievement of optimal or near-optimal fire return intervals for the higher-priority conservation objectives, by applying a quantitative methodology to fire management planning. We recommend using decision-support frameworks and models for managing fire return intervals, while also accounting for finer-scale fire characteristics, such as patchiness, seasonality, severity, and intensity.

Fear as an enemy? Behavioral changes of Ananteris mauryi (Scorpiones: Buthidae) triggered by chemical cues from an intraguild predator

et al. 2022

Fear level and intraguild predation are factors that act together to directly influence animal behavior, population dynamics, and community structure. These factors trigger stress, which promotes behavioral, morphological, physiological, and demographic changes, especially in the prey. Some invertebrates, such as scorpions, are known to have a refined chemoreception system to perceive both prey and predators. Therefore, we investigated the ability of an intraguild prey, the scorpion Ananteris mauryi Lourenço, 1982, to detect chemical traces of its predator, the scorpion Tityus pusillus Pocock, 1893. Our goal was to verify whether A. mauryi exhibits antipredator behavior induced exclusively by chemical cues from its predator. Ananteris mauryi specimens were subjected to two experimental treatments: one with and one without traces of T. pusillus. The results showed that A. mauryi tended to avoid substrates with chemical traces of T. pusillus, confirming its capacity for chemical detection. As a result of this perception, changes in behavioral frequencies were triggered, generating an antipredator behavioral repertoire. These findings were supported by behavioral changes, such as tail wagging, which is performed exclusively by scorpions in the presence of a predator and at imminent risk of predation.

Background Several insectivorous bat species are found in New England, yet research on them is still scarce. Current research shows the ecological importance of bats due to their control of insect populations, but they are endangered by habitat loss and White Nose Syndrome, among other threats. Pine barrens are an uncommon ecosystem found in New England that supports other rare taxa and could be important for these bat species. Methods With hand-held audio recorders, we surveyed for bats in Montague Plains Wildlife Management Area in Massachusetts and Concord Pine Barrens in New Hampshire in June 2022. Our study objectives were to (1) describe the most common bat species and (2) compare bat activity across different habitat types at two managed pine barrens in New England. In particular, we examined bat activity related to habitat type (scrub oak, mature pitch pine, treated pitch pine, hardwood forest), habitat structure (i.e., canopy closure), time since prescribed fire, and path width. We analyzed our data through generalized linear modeling and logistic regression. Results Overall, we were able to measure the presence of five out of the nine total species found in the area, including the endangered Myotis lucifugus (little brown bat). We recorded 293 bat calls, with the majority of calls from big brown bats (71%). We found significant differences (p < 0.05) in bat activity in relation to time since prescribed fire and habitat structure. The index of bat activity was greatest in pitch pine and hardwood forests and lowest in scrub oak and treated pitch pine habitats. With preliminary data, we also found that silver-haired bat presence was influenced by habitat type, with more detections at survey points in hardwood forests. Discussion These findings demonstrate the importance of pine barrens as an ecosystem that supports bats in New England. According to the activity of bats in our study, closed canopy and mature pitch pine habitats may be prioritized in conservation efforts at managed barrens for bat species. Further research is recommended to better understand the relationship between prescribed fires, which are common in managed barrens, and bat activity.
