Journal ArticleDOI
Herbivore effects on plant species density at varying productivity levels
Laura Gough,James B. Grace +1 more
TL;DR: The results of this experiment support those of other fertilization studies in which plant species density decreases with increased biomass, but only in those plots protected from herbivory.
Journal ArticleDOI
Structural Equation Modeling for Observational Studies
TL;DR: 2 example applications of Structural equation modeling are presented, one involving interactions among lynx, mongooses, and rabbits, and the second involving anuran species richness.
Journal ArticleDOI
Streams in the urban heat island: spatial and temporal variability in temperature
Kayleigh A. Somers,Emily S. Bernhardt,James B. Grace,Brooke A. Hassett,Elizabeth B. Sudduth,Si-Yi Wang,Dean L. Urban +6 more
TL;DR: In this article, the authors collected continuous (10-min interval) temperature data in 60 streams spanning a range of development intensity in the Piedmont of North Carolina, USA, and found that urbanized streams averaged 21.1°C at baseflow, compared to 19.5°C in the 5 most forested streams.
Journal ArticleDOI
Does urban sprawl hold down upward mobility
TL;DR: In this article, the authors examine potential pathways through which sprawl may have an effect on mobility and use structural equation modeling to account for both direct and indirect effects of sprawl on upward mobility.
Journal ArticleDOI
Landscape-scale analyses suggest both nutrient and antipredator advantages to Serengeti herbivore hotspots
T. Michael Anderson,J. Grant C. Hopcraft,J. Grant C. Hopcraft,Stephanie Eby,Mark E. Ritchie,James B. Grace,Han Olff +6 more
TL;DR: This study studied direct and indirect influences on the spatial distributions of Serengeti herbivore hotspots, defined as temporally stable areas inhabited by mixed herds of resident grazers, and highlighted the collective and simultaneous role of bottom-up and top-down factors in determining ungulate spatial distributions.
