Summary: Restoration of longleaf pine forests is a key land management goal in the southern United States, and fire is an important ecological factor for these forests. Longleaf pine seedlings exhibit high resistance and resilience to fire intensity in different seasons, with some vulnerability to high-intensity summer fires.

Summary: Planting rates and density affect the ecological and timber quality aspects of longleaf pine plantations. Higher planting density results in smaller tree diameters and larger stand basal area, while higher planting rates lead to lower branch density and lower straightness grades. Increasing stand density reduces canopy openness and ground cover, decreasing herbaceous plant cover.

Summary: This study compared crown metrics derived from terrestrial and airborne laser scanners, as well as a combination of both, for describing the crown structure and fuel attributes of longleaf pine forest in Florida, USA. The results showed that both terrestrial and airborne laser scanner data accurately predicted tree attributes with good correlation and low errors.

Summary: Research on the impact of reduced rainfall on longleaf pine indicates that decreased precipitation may have minimal effects on shoot and needle growth and phenology, as well as canopy development and litter production.

Summary: The removal of invasive species can have positive impacts on native species, increasing survival rates and population growth of certain small mammals. However, the effects of red-imported fire ants on small mammals are complex and not entirely predictable.

Summary: Natural regeneration of longleaf pine in the Escambia Experimental Forest in southern Alabama showed patchy distribution across various site and stand conditions, with density of seedlings and saplings varying significantly. Longer fire intervals are needed for successful natural regeneration of longleaf pine.

Summary: Research showed that longleaf pines planted at lower densities had more and larger live lower branches compared to higher density plantings. Prescribed fires were effective in pruning lower branches, with fires in the growing season being more effective. The fires did not impact the survival of longleaf pine trees.

Summary: The study evaluates the long-term survival and growth response of longleaf pine to commonly used herbicides and application timings. It found that different herbicides and application timings can significantly affect the survival and growth of longleaf pine, with some treatments resulting in higher survival rates and better growth parameters after 11 years.

Summary: Longleaf pine ecosystems, which were historically widespread in certain regions of North America, have suffered extensive loss due to human activities. This study used fire scars in stumps and snags to reconstruct the fire history in a longleaf pine ecosystem in the piedmont region of North Carolina. The results revealed evidence of frequent fires occurring from the early 18th century to the mid-19th century, offering a valuable insight into the historical fire activity in this important ecological setting. Further research is needed to expand the fire chronologies in the piedmont region for longer time periods and larger areas.

Summary: Longleaf pine radial growth is primarily controlled by late summer rainfall, with adjusted latewood growth showing the strongest relationship with climate. There is spatial similarity in growth/climate responses across the Coastal Plain region, while temporally, July-September precipitation has significant relationships with radial growth for extended periods. Growth/climate relationships are stronger for latewood compared to earlywood.

Summary: The study shows that headstarting can effectively protect terrestrial mammals whose early life stages are vulnerable to introduced predators. Bridled nailtail wallabies isolated from predators in a 9.2 ha predator-free fenced exclosure and released into the wild did not show any differences in dispersal, body condition, or survival compared to wild-raised wallabies.

Summary: The study investigates the response of bilbies to the scents of dingoes and feral cats, finding that the wild-living bilbies displayed anti-predator responses towards both long-term and evolutionary novel predators. This suggests that exposure to introduced predators can help native species develop anti-predator responses, overcoming predator naivete through learning and natural selection.

Summary: This study investigates the impact of anthropogenic disturbances on plant communities in the Wade Tract area. It finds that disturbed sites have fewer indicator species and different soil conditions compared to adjacent or reference sites. The findings highlight the importance of avoiding disturbances in the restoration of longleaf pine woodlands.

Summary: This study analyzes the spatiotemporal co-occurrences between predators and prey in a community of mammals. The results suggest that prey show avoidance behavior in both space and time where predators have passed. Contrary to expectations, predators did not show significant search behaviors towards prey. The study provides insights into the behavior mechanism between predators and prey in the ecosystem.
