Seasonal space use of transient and resident coyotes in North Carolina
Coyote (Canis latrans Say, 1823) is a recent immigrant into eastern United States, and little is known about the speciesâ space use and movement in the region. We compared space use and movement of radio-collared coyotes among biological seasons. We captured and collared 30 coyotes from February through May 2011 and collected 85,386 GPS locations through October 2012 at Fort Bragg Military Installation. We defined 4 biological seasons according to coyote life history: breeding (DecemberâFebruary), gestation (MarchâMay), pup-rearing (JuneâAugust), and dispersal (SeptemberâNovember). Out of 27 radio-collared individuals, we identified 10 as transient and 11 as resident based on home range size and variability across seasons; 6 switched their status and were classified as intermediate. We observed low variability of core area size across seasons for resident males and females, whereas we documented high variability for transient males. Movement rate of resident coyotes during spring (449.75 m/hr) was greater than summer (295.33 m/hr), whereas movement rates did not differ between any other seasons. For transient coyotes, movement rate during summer (283 m/hr) was less than fall (374.73 m/hr), spring (479.85 m/hr), and winter (488.5 m/hr). Some coyotes adjusted their residency status seasonally and other individuals dispersed large distances (> 200 km).The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Resource selection by coyotes (Canis latrans) in a longleaf pine ecosystem: effects of anthropogenic fires and landscape features
Prescribed fire is used to restore and maintain fire-dependent forest communities. Because fire affects food and cover resources, fire-mediated resource selection has been documented for many wildlife species. The first step in understanding these interactions is to understand resource selection of the predators in a fire-maintained system. We attached GPS radiocollars to 27 coyotes (Canis latrans Say, 1823) and examined resource selection relative to fire-maintained vegetation types, years-since-fire, anthropogenic features that facilitate prescribed burning, and other landscape features likely to affect coyote resource selection. Coyote home ranges were characterized by more open vegetation types and more recently burned forest (i.e., burned 0 Ăą 1 year prior) than available on the study area. Within their home ranges, coyotes avoided areas close to densely vegetated drainages and paved roads. Coyote selection of more recently burned forest likely was in response to greater prey density or increased ability to detect prey soon after vegetation cover was reduced by fires; similarly, coyotes likely avoided drainages due to decreased hunting efficiency. Coyote resource selection was linked to prescribed fire, suggesting the interaction between fire and coyotes may influence ecosystem function in fire-dependent forests.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Effects of body size on estimation of mammalian area requirements
Accurately quantifying species' area requirements is a prerequisite for effective area-based conservation. This typically involves collecting tracking data on species of interest and then conducting home-range analyses. Problematically, autocorrelation in tracking data can result in space needs being severely underestimated. Based on the previous work, we hypothesized the magnitude of underestimation varies with body mass, a relationship that could have serious conservation implications. To evaluate this hypothesis for terrestrial mammals, we estimated home-range areas with global positioning system (GPS) locations from 757 individuals across 61 globally distributed mammalian species with body masses ranging from 0.4 to 4000 kg. We then applied block cross-validation to quantify bias in empirical home-range estimates. Area requirements of mammals 1, meaning the scaling of the relationship changed substantially at the upper end of the mass spectrum
Mainstreaming African Diasporic Foodways When Academia Is Not Enough
More than a decade after Britain's bicentennial commemoration of the 1807 Abolition Act to end the Transatlantic Slave Trade, Scotland still struggles to reconcile her colonial past. Unlike in North America, historical archaeology centered on the history and legacy of the transatlantic slave trade is still highly marginalized in British academia. Furthermore, Scotland's roles in slave-based economies is only recently being considered a relevant area of historical studies. This paper emerges from my evolving perspective as a Black American scholar and resident in the United Kingdom, as I strive to create intellectual spaces in and outside of academia. Through civic engagement, I use my work on African diasporic foodways in the French Caribbean to link with a similar material basis of resistance in the British Caribbean and engage British audiences whose connections to Atlantic slavery are yet to be fully recognized
