Quantifying habitat use is vital to understanding animal ecology. Herein, we contrast classification-based (i.e., locations are placed into categories for subsequent analyses) and distance-based distance between features used in approaches analyzing data. Compositional analysis (CA) a (DA) were quantify selection of Northern Bobwhite (Colinus virginianus). We qualitatively compared the outcome these different procedures illustrate advantages DA approach. The approach identified edges as an...
Carrion is a valuable nutrient resource used by diversity of vertebrates across the globe. However, vertebrate scavenging ecology remains an understudied area science, especially in regards to how biotic and abiotic factors influence community composition. Here we elucidate fundamental interact modulate efficiency composition scavengers investigating dynamics large gradient carcass sizes habitat types representative many temperate ecosystems, as well between two seasons reflecting...

Species intolerant to fire, defined as lacking adaptations needed establish dominance in a frequently burned landscape, are found within fire-prone ecosystems globally. Such species targeted for reduction or eradication further conservation restoration of biological diversity because the dominant paradigm fire-dependent communities is reduce eliminate fire-intolerant invaders. To explore this paradigm, we examined role oaks (Quercus spp.) upland and sandhill longleaf pine (Pinus palustris)...
Costs associated with antipredator behaviors can have profound effects on prey populations. We investigated the of predation risk white-tailed deer foraging behavior by manipulating predator distributions through exclusion while controlling for habitat type. In 2003, we constructed exclosures 4 8 approximately 40-ha study plots in southwestern Georgia, USA. examined seasonal and sex-specific exclusion, group size composition behavioral state (i.e., feeding or vigilant) at baited camera traps...

Filter-feeding mussels historically comprised most of benthic biomass in many streams. They contribute to stream ecosystem functioning by linking the water column and habitats. Both native nonnative species coexist streams, but their ecological roles are not well quantified. The invasive bivalve, Corbicula fluminea, has potential alter profoundly organic matter dynamics nutrient cycling We compared stable isotope ratios tissue biodeposit stoichiometry freshwater mussel, Elliptio crassidens,...
Some tick populations have increased dramatically in the past several decades leading to an increase incidence and emergence of tick-borne diseases. Management strategies that can effectively reduce while better understanding regional phenology is needed. One promising management strategy prescribed burning. However, efficacy burning as a mechanism for control unclear because studies provided conflicting data, likely due failure some simulate operational scenarios and/or account other...
Abstract Control of mid‐sized mammalian predators (hereafter, mesopredators) is sometimes advocated in an attempt to reduce their impact on wildlife populations, particularly economically important (i.e., game) or endangered species. However, mesopredators may play a role regulating small mammal populations; thus, lethal control have unintended consequences. The hispid cotton rat ( Sigmodon hispidus ; hereafter, rat) one the most common mammals southeastern United States and prey species for...
ABSTRACT Lethal control of coyotes ( Canis latrans ) is a mechanism for increasing white‐tailed deer Odocoileus virginianus recruitment but can be difficult to implement and may ineffective on small parcels land because coyote immigration. In 2003, we constructed 4 40‐ha mesopredator exclosures with the objective quantifying influence mesopredators, including coyotes, select wildlife populations communities. Camera trapping indicated neonate/adult female ratios were approximately 2 times...
Global positioning system (GPS) technologies have improved the ability of researchers to monitor wildlife; however, use these is often limited by monetary costs. Some begun commercially available GPS loggers as a less expensive means tracking wildlife, but data regarding performance devices are limited. We tested logger (i–gotU GT–120) placing at ground control points with locations known < 30 cm. In preliminary investigation, we collected every 15 minutes for several days estimate location...
Abstract Predation risk can induce individual prey to express behavioral, physiological, and morphological traits that influence population‐level processes. Maternal care is an intuitive link between predator‐mediated of individuals processes because maternal investment decrease with predation risk, often influences such as neonatal growth, survival, recruitment. During fawn‐rearing, many ungulate species restrict space use a fraction their home range. Selection within these areas the...
The ecological implications of coyote Canis latrans colonization the eastern USA have drawn considerable interest from land managers and general public. ability to predict how these ecosystems, which lacked larger predators for decades, would respond invasion this highly adaptable species needs an understanding foraging behavior given local resource availability. Therefore, we examined diet coyotes in a longleaf pine Pinus palustrus ecosystem 2007–2012. We 673 scats collected on Joseph W....
ABSTRACT Management of longleaf pine ( Pinus palustris ) forests relies on frequent prescribed fire to maintain desirable plant communities. Prescribed is often applied while female wild turkeys Meleagris gallopavo are reproductively active and may immediately affect habitat availability demographic outcomes. We identified covariates affecting selection areas used by nesting brooding females determined if these influenced nest brood survival in a ecosystem. captured 63 measured vegetation...
ABSTRACT Although nest predation is often the single largest source of mortality in avian populations, manipulative studies to determine predator impacts on survival are rare, particularly that examine mid‐size mammalian predators (hereafter, mesopredators) shrub‐nesting birds. We quantified and identified songbirds within 4 large (approx. 40‐ha) exclosures control sites a longleaf pine ( Pinus palustris ) ecosystem. During 2003–2006, we located monitored 535 shrub nests (222 with...
Food resources and predation play important roles in determining small mammal population dynamics. These factors also can interact as individuals under pressure make trade-offs between access to food exposure predators. Fires consume sources reduce cover, which increases For species that occur areas with frequent fire, it is instructive consider how all of these affect populations interest. We examined supplemental feeding, mammalian predator exclusion, prescribed fire affected survival,...
The ecological restoration of fire-suppressed habitats may require a multifaceted approach. Removal hardwood trees together with reintroduction fire has been suggested as method restoring longleaf pine (Pinus palustris) forests; however, this strategy, although widespread, not evaluated on large spatial and temporal scales. We used landscape-scale experimental design to examine how bird assemblages in sandhills responded alone or following mechanical removal herbicide application reduce...
Abstract Gopher tortoise ( Gopherus polyphemus ) populations are declining throughout the Southeast, and high levels of predation on nests juveniles have been suggested as a potential contributor to this decline. Therefore, we documented gopher nest success hatchling survival relative mammalian predator control. We used 4, large (approx. 40‐ha) fenced, exclosures exclude mid‐sized predators: bobcat Lynx rufus ), raccoon Procyon lotor Virginia opossum Didelphis virginianus fox Urocyon...
Raccoons (Procyon lotor) are important furbearers and ecological generalists that exist in a variety of landscapes. Numerous studies have examined raccoon space macrohabitat use, but information detailing these parameters within pine-dominated landscapes is lacking. Furthermore, no using radiotracking habitat use at multiple spatial scales. We radiomonitored 131 adult raccoons (99 M, 32 F) during 1991-1997 central Mississippi, USA. subsequently assessed selection 3 Males maintained larger...
Many factors influence bobcat (Lynx rufus) space use, movements and habitat selection, including prey distribution density, season, breeding behaviors intraspecific relationships. Knowledge of ranging selection is required to understand population dynamics ecology bobcats within temperate ecosystems. We radio-monitored 58 adult from 1989–1997 in central Mississippi. Males maintained larger home ranges core areas than females, but sizes these did not vary seasonally. Male moved at greater...
