Data from: Pathogen persistence in the environment and insect-baculovirus interactions: disease-density thresholds, epidemic burnout, and insect outbreaks

Emma Fuller, Bret D. Elderd & Greg Dwyer
Classical epidemic theory focuses on directly transmitted pathogens, but many pathogens are instead transmitted when hosts encounter infectious particles. Theory has shown that for such diseases pathogen persistence time in the environment can strongly affect disease dynamics, but estimates of persistence time, and consequently tests of the theory, are extremely rare. We consider the consequences of persistence time for the dynamics of the gypsy moth baculovirus, a pathogen transmitted when larvae consume foliage contaminated with...

Data from: Small-scale variation in fuel loads differentially affects two co-dominant bunchgrasses in a species-rich pine savanna

Paul R. Gagnon, Kyle E. Harms, William J. Platt, Heather A. Passmore & Jonathan A. Myers
Ecological disturbances frequently control the occurrence and patterning of dominant plants in high-diversity communities like C4 grasslands and savannas. In such ecosystems disturbance-related processes can have important implications for species, and for whole communities when those species are dominant, yet mechanistic understanding of such processes remains fragmentary. Multiple bunchgrass species commonly co-dominate disturbance-dependent and species-rich pine savannas, where small-scale fuel heterogeneity may influence bunchgrass survival and growth following fires. We quantified how fire in locally...

Data from: The role of physical barriers in the location of avian suture zones in the Guiana Shield, northern Amazonia

Luciano Nicholas Naka, Catherine L. Bechtoldt, L. Magalli Pinto Henriques, Robb T. Brumfield & Luciano Nicolas Naka
Suture zones represent natural forums to examine the role of geography and ecology in the speciation process. Here, we conduct a comparative analysis designed to investigate the location of avian phylogeographic breaks and contact zones in the Guiana Shield, northern Amazonia. We use distributional and genetic data from 78 pairs of avian taxa to address whether phylogeographic breaks and contact zones are associated with contemporary landscape features. Using spatially explicit statistical models, we found that...
