Predicting breastfeeding in women living in areas of economic hardship : explanatory role of the theory of planned behaviour

This study employed the theory of planned behaviour (TPB) and additional variables (descriptive norm, moral norm, self-identity) to investigate the factors underlying breastfeeding intention and subsequent breastfeeding at four time points (during hospital stay, at hospital discharge, 10 days postpartum and 6 weeks postpartum) in a sample of women selected from defined areas of economic hardship (N = 248). A model containing the TPB, additional variables and demographic factors provided a good prediction of both intention (R-2 = 0.72; attitude, perceived behavioural control, moral norm and self-identity significant predictors) and behaviour - breastfeeding at birth (88.6% correctly classified; household deprivation, intention, attitude significant), at discharge from hospital (87.3% correctly classified; intention, attitude significant), 10 days after discharge (83.1% correctly classified; education, intention, attitude, descriptive norm significant) and 6 weeks after discharge (78.0% correctly classified; age, household deprivation, ethnicity, moral norm significant). Implications for interventions are discussed, such as the potential usefulness of targeting descriptive norms, moral norms and perceived behavioural control (PBC) when attempting to increase breastfeeding uptake

Scent Deterrence to Reduce Southern Flying Squirrel Kleptoparasitism of Red-Cockaded Woodpecker Cavities

When establishing new populations of endangered red-cockaded woodpeckers (RCW; Picoides borealis), cavity kleptoparasites can pose a considerable obstacle to successful restoration. Southern flying squirrels (SFS; Glaucomys volans) are the principal kleptoparasite of RCW roost and nest cavities. Managers restoring RCW populations primarily use labor-intensive, direct removal to mitigate cavity competition by SFS. We fi eld tested the use of red fox (Vulpes vulpes) urine and rat snake (Elaphe spp.) musk as predator scents to examine if SFS could be deterred from using RCW cavities and to observe RCW roost behavior at cavities treated with red fox urine. Scent deterrence proved ineffective in preventing SFS use of RCW cavities, while RCWs showed no behavioral response to scent treatment. Managers should continue using squirrel excluder devices, and direct removal to mitigate SFS kleptoparasitism of RCW cavities when restoring critically endangered populations

Evaluation of Attractants for Live-Trapping Nine-Banded Armadillos

In the past 50 years, the range of the nine-banded armadillo (Dasypus novemcinctus) in the south has been rapidly expanding. As their range expands, armadillos increasingly come into conflict with suburban landowners. When foraging, armadillos often uproot ornamental plants. Their rooting also destroys gardens, lawns, and flower beds. Their burrowing can damage tree roots and building foundations. Most armadillo damage is a result of their feeding habits. Armadillos dig shallow holes, 1- 3 inches deep and 3-5 inches long, as they search for soil invertebrates. A recent survey of Georgia county extension agents by scientists at the University of Georgia found that 77.6% of all agents reported receiving complaints or requests for information on armadillos. Armadillo related inquiries made up 10.1 % all inquiries for all agents across the state, surpassing even the white-tail deer (Odocoileus virginianus). Armadillos are often assumed to destroy nests of ground-nesting birds. Armadillo diets have been studied in several states including Alabama, Louisiana, Texas, Georgia, Arkansas, and Florida. According to these studies, vertebrate matter, especially bird eggs, made up an minor portion of their diet. The armadillo’s diet often consists of more than 90% insects, grubs and earthworms. Based on these studies, it seems that claims of armadillos being significant nest predators are unfounded

Survival and cause-specific mortality of female eastern wild turkeys in two frequently-burned longleaf pine savannas

Longleaf pine savannas have declined throughout the southeastern United States due to land-use change. Fortunately, natural resource professionals are currently restoring these ecologically and economically important savannas. Although efforts are underway to restore longleaf pine savannas, little information exists on female eastern wild turkey Meleagris gallopavo silvestris population dynamics in these systems. Therefore, we evaluated survival and cause-specific mortality of female eastern wild turkeys in two longleaf pine savannas in southwestern Georgia. We radio-marked 126 female wild turkeys during 2010–2013 and monitored their survival; 66 (52.4%) radio-marked females died during the study. We estimated causes of death for 37 mortality events with predation serving as the leading known cause of mortality, with 35.1% of mortalities attributed to mesocarnivore predation (e.g., bobcat Lynx rufus, coyote Canis latrans, and gray fox Urocyon cinereoargenteus) and 18.9% to great-horned owl Bubo virginianus predation. One female (2.7%) was hit by a vehicle. Seasonal survival estimates varied from a high during fall (Ŝ = 0.94; 95% CI: 0.86–1.00) to a low during spring (Ŝ = 0.76; 95% CI: 0.68–0.87). Survival of incubating females was 0.82 (95% CI: 0.71–0.93) and survival of nonincubating females was 0.67 (95% CI: 0.52–0.87). Annual survival was 0.55 (95% CI: 0.44–0.67). To ensure sustainable wild turkey populations in longleaf pine savannas, we suggest managers monitor relationships between survival and population productivity

Adult bobcat (\u3ci\u3eLynx rufus\u3c/i\u3e) habitat selection in a longleaf pine savanna

Background: Pine savannas are primarily managed with frequent prescribed fire (≤ 3 years) to promote diversity of flora and fauna, and to maintain open, park-like conditions needed by species such as the endangered red-cockaded woodpecker (Picoides borealis). However, a knowledge gap exists in our understanding of bobcat (Lynx rufus) habitat selection in longleaf pine savannas and research is warranted to direct our future management decisions. Methods: We examined bobcat habitat selection in a pine savanna managed with frequent fires at two spatial scales (i.e., study area boundary [hereafter, landscape scale]) and annual area of use [95% kernel density; local scale]), and assessed effects of prescribed fire on bobcat habitat selection. Specifically, we monitored 45 bobcats (16 males and 29 females) during 2001–2007. Results: We found differential habitat selection by sex. At the landscape scale, female bobcats were closer to mixed pine-hardwoods, young pine, and secondary roads, but farther from mature pine and hardwoods stands relative to males. We found no difference in selection of agriculture, shrub-scrub, and primary roads between sexes. At the annual area of use scale, female bobcats were closer to secondary roads, but farther from agriculture and shrub-scrub relative to males. We found no difference in selection of mature pine, mixed pine-hardwoods, hardwoods, young pine, and primary roads between sexes. Bobcats primarily selected for stands burned ≤ 1.1 years post-fire. Conclusions: Our results show that bobcats exploit a broad range of habitat types in pine landscapes managed with frequent fire and commonly use recently burned stands (≤ 1.1 year post-fire), suggesting prey in many areas of this system are at risk of bobcat predation. Additionally, we suggest land managers consider scale of selection by bobcats when developing habitat management strategies

Nest and brood site selection of eastern wild turkeys

Management of longleaf pine (Pinus palustris) forests relies on frequent prescribed fire to maintain desirable plant communities. Prescribed fire is often applied while female wild turkeys (Meleagris gallopavo) are reproductively active and may immediately affect habitat availability and demographic outcomes. We identified covariates affecting selection of areas used by nesting and brooding females and determined if these covariates influenced nest and brood survival in a longleaf pine ecosystem. We captured 63 female wild turkeys and measured vegetation and landscape characteristics surrounding nests, brood roosts, and daytime use sites. We used conditional logistic regression to determine which vegetation and landscape-scale characteristics influenced nest, brood roost, or daytime use sites. We generated Cox proportional hazard models at multiple spatial scales to determine if selection influenced nest and brood survival. Females selected nest sites with greater visual obstruction and increased ground cover, and also nested closer to roads. We observed relevant differences in vegetation and landscape variables associated with where females chose to roost broods compared to sites chosen for foraging or loafing. Females roosted broods at sites with increased ground cover and decreased visual obstruction, and daytime use by broods was most related to increases in ground cover. Time-since-fire was an informative covariate for brood site selection but not for nest site selection. Females selected brood roost sites in stands not recently burned (3–6 yr post-fire), and selected daytime use sites in stands burned the current year (0 yr post-fire) and 2 years post-fire. We failed to observe links between selection of vegetation and landscape covariates and probability of nest or brood survival. Notably, our results suggest short (i.e., 1–2 yr) fire return intervals do not provide vegetation communities selected by females to roost broods. Conversely, stands burned within the current year were important for daytime use by broods. Collectively, our findings demonstrate the importance of maintaining diverse fire return intervals to ensure availability of vegetation conditions necessary for nesting and brooding. © 2018 The Wildlife Society

Eastern wild turkey nest site selection in two frequently burned pine savannas

Introduction: Reproductive success is a critical factor affecting avian demographics and can be influenced by many factors including nesting chronology, predation risk, and fine-scale nest site selection. Methods: We modeled the relative influences of habitat-related covariates at six spatial scales (nest site: 15-, 40-, 80-, 120-, 160-, and 200-m radii) on Eastern wild turkey (Meleagris gallopavo silvestris) nest site selection in two pine savannas managed by frequent prescribed fire (≤3 years) in southwestern Georgia during 2011–2013. Results: Nest site (15-m scale) habitat metrics (mean visual obstruction [cm] and canopy closure [%]) had the greatest influence on nest site selection relative to covariates measured at larger spatial scales. Scaled odds ratios suggested that nests were 26.8 % more likely to occur for every 10 cm increase in mean vegetation height with a range of 7.5 to 150.0 cm and 18.5 % less likely to occur for every 10 % increase in canopy closure with a range from 0.0 to 97.8 %. Total ground cover, canopy closure, edge density, and percent land cover type (e.g., mature pine, mixed pine/hardwood, shrub/scrub) had minimal influence on nest site selection. Conclusions: Management of pine savannas for turkey nest sites should focus on creating early-successional vegetation to conceal nests from potential predators. Additionally, we suggest that future studies consider evaluating the influence of spatial scale on turkey nest site selection
