In Tennessee, an intensely burned plot of forest (2016) presented a unique opportunity to analyze successional habitat regrowth 2–3 years after a wildfire occurred. To examine post-fire recovery, we observed the diversity of avian species in 1 burned site (1-km transect) and 1 unburned site (690-m transect) during 2018–2019. We used line-transects to examine avian diversity and performed a vegetation analysis to compare the sites. Our results showed that though the unburned site was higher in avian diversity (mean Shannon diversity: 2.844 in unburned vs. 2.521 in burned), the burned site appeared to be suitable habitat for multiple disturbance-dependent avian species. Bird species associated with low to medium vegetation heights and overstory heights and low residual basal areas in early successional forests, such as Setophaga discolor (Prairie Warbler), Passerina cyanea (Indigo Bunting), and Icteria virens (Yellow-breasted Chat), were found only in the burned site, suggesting the fire created suitable habitat for these species, with its average canopy height of 3.55 m and canopy coverage of 18.75%.This study supports the need for greater fire research in Eastern deciduous forests. The results suggest regular fires could create patches of habitats that benefit struggling species of disturbance-dependent birds in this region.","PeriodicalId":49490,"journal":{"name":"Southeastern Naturalist","volume":"306 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135597240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared to other areas of the Atlantic Coastal Plain, sites in the Carolina Sandhills often have higher restoration potentials for Longleaf Pine habitat. Distinct sandhill ecology and prevailing biological legacies make Longleaf Pines competitive in this region. Spatial investigations into potential restoration sites are essential preliminary steps to optimize resource allocation for large-scale restoration objectives. This study aimed to illustrate the applicability of various modeling techniques while providing a framework for restoration-parcel identification and selection. We developed multiple weighted spatial multi-criteria decision models to identify Longleaf Pine-restoration sites in the South Carolina Sandhills Wiregrass Gap, an ecologically distinct and understudied region of Longleaf Pine occupancy. Using advanced spatial modeling and analysis tools, we developed a classification system that combined and weighted vegetation cover, land use, and soil property raster data. The models are designed to identify potential sites for restoration, which will ultimately improve resource allocation during the project planning process. We found significant (P < 0.001) spatial clustering of large parcels and 94.7–98.3% pixel similarity between predictive models. An ensemble model, developed by averaging the pixel values of each predictive model, found that Longleaf Pine-restoration potential was highest in large rural parcels primarily east of Kershaw County. Large-parcel clustering and ecological input factors applied to a decision-making model in this study provide a precedent for systematically allocating resources to improve and increase forest restoration and management in South Carolina.","PeriodicalId":49490,"journal":{"name":"Southeastern Naturalist","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136060696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Behavior of nesting hen Meleagris gallopavo (Wild Turkey) may vary due to landscape features (e.g., roads, water source, or pastureland), potentially influencing predator encounter rates at the nest and consequently affecting nest survival. We assessed factors affecting nest survival and hen survival during incubation, including temporal patterns of M. g. osceola (Osceola Wild Turkey) and M.g. silvestris (Eastern Wild Turkey) recess behaviors. We used data on recess bouts from 37 hens fitted with global positioning system (GPS) transmitters and 54 confirmed nest attempts in north and north-central Florida to determine the effect of nest attendance on nest survival. On average, hens took 0.89 incubation recess bouts between 0800 and 1800, usually in the afternoon. Hen survival increased with an increase in daily recess bouts, longer daily recess bouts, and later nest incubation-initiation dates, and the probability of nest survival increased when hens took longer afternoon recess bouts. Nest survival was greater in the north-central region. These results indicate increases in recess duration contribute to greater hen and nest survival, which may be due to reduced nest-predator activity in the afternoon at the study sites. We recommend additional research into the relationship between predator activity and nesting Wild Turkeys on managed lands similar to those in our study.","PeriodicalId":49490,"journal":{"name":"Southeastern Naturalist","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136060692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective was to establish baseline inventories on existing plants and wildlife including flora, herpetofauna, birds, invertebrates, and mammals for future monitoring of key wildlife species. Some of the general habitat types and vegetation zones that were surveyed included prairies, hardwood hammocks, pine flatwoods, cypress swamp forest, hardwood swamps, and depression marshes. This survey was the first attempt to formally inventory the biodiversity of Green Glades Ranches West, where we documented over 275 different species, including several that are either endangered, threatened, invasive, endemic, or previously unknown to occur in Hendry County. These results highlight the important role of private land holdings, especially those adjacent to statutory protected areas and strategic wildlife corridors, in achieving and supporting regional conservation initiatives and wildlife-management goals.","PeriodicalId":49490,"journal":{"name":"Southeastern Naturalist","volume":"116 1","pages":"364 - 378"},"PeriodicalIF":0.6,"publicationDate":"2023-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76098120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is still a poor understanding of the impacts damaging hail can have on ungulate survival. We had a unique case study, when a hailstorm produced hailstones up to ∼7 cm in diameter in the area of Camp Hill, AL, and the nearby Auburn Captive Deer Facility (ACF) on 26 March 2023. With the ACF being completely enclosed with fencing, we were able to conduct extensive surveys for mortality cases of Odocoileus virginianus (White-tailed Deer) shortly after the hailstorm. We detected no cases of mortality attributed to the storm. We speculate that no mortality occurred due to the ACF containing mature forests with adequate overstory that provided structural cover for deer from hailstone strikes. Further examination of the literature found that a substantial proportion of hail-induced mortality has occurred in agricultural areas, wetlands, and grasslands where there was limited to no canopy cover. This result may suggest that deer inhabiting forested regions are at less risk from hailstorms compared to conspecifics inhabiting open habitat.","PeriodicalId":49490,"journal":{"name":"Southeastern Naturalist","volume":"200 1","pages":"379 - 396"},"PeriodicalIF":0.6,"publicationDate":"2023-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76040953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comparing spatial patterns of song-type sharing may allow us to infer song-learning strategies and dispersal behavior for any given species or population. Song learning and dispersal are unknown for Peucaea aestivalis (Bachman's Sparrow), an endemic songbird of the southeastern United States that is declining throughout much of its range and is considered to be near threatened. Our objective was to compare the number of song-types shared among male Bachman's Sparrows to make inferences about song development and dispersal. From 2016 to 2019, we recorded male sparrow songs in 3 different sites in South Florida, and determined song-type repertoires and song-type sharing among males within and between sites by visually comparing individual song spectrograms. Repertoire size varied among individuals and sites. Within sites, sharing did not decline with distance; between sites, sharing correlated with geographic distance between males, with song-type sharing greater at closer distances and lower at farther distances. These data suggest that Bachman's Sparrows may have an extended song-learning period and typically attempt short-distance dispersals from natal areas but disperse farther if suitable and vacant territories are not available nearby.","PeriodicalId":49490,"journal":{"name":"Southeastern Naturalist","volume":"61 1","pages":"315 - 332"},"PeriodicalIF":0.6,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91032709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adelgid piceae (Balsam Wooly Adelgid) depredation that induced high mortality and chronic losses, and other anthropogenic causes, have led to Fraser Fir being designated as an endangered species by the IUCN Red List. There is great interest in restoring Fraser Fir through managed reforestation efforts, especially in protected areas such as Great Smoky Mountains National Park. To optimize Fraser Fir reestablishment in formerly forested sites, we designed a study to examine reforestation success by comparing survival and growth using treatments including mycorrhizal seedling transplants, local seedling transplants, local soil inocula, and mulching conditions to suppress surrounding vegetation. We found that while some treatments increased seedling survival and growth, any benefit was slight compared to local seedling transplants from adjacent mature Fraser Fir stands and/or local soil inocula. Greenhouse manipulations were more costly and time intensive for very little added benefit. We conclude that transplanting local seedlings with native soil to restore damaged sites provides the maximum return on investment and is a viable option for reforestation of Fraser Fir, but a sufficient local seedling bank may not always be available.","PeriodicalId":49490,"journal":{"name":"Southeastern Naturalist","volume":"109 1","pages":"333 - 351"},"PeriodicalIF":0.6,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74104891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
