Data from: Does prey encounter and nutrient content affect prey selection in wolf spiders inhabiting Bt cotton fields?

Dalila Rendon, Phillip W. Taylor, Shawn M. Wilder & Mary E.A. Whitehouse
Wolf spiders are abundant and voracious predators at the soil-plant interface in cotton crops. Among other prey, they attack late-instar larvae of the cotton bollworm Helicoverpa spp., an economically important pest. Consequently, wolf spiders in transgenic Bt cotton could provide significant biological control of Bt-resistant Helicoverpa larvae that descend to the soil to pupate. The predator-prey interactions between wolf spiders and Helicoverpa could, however, be constrained by the presence of alternative prey and intraguild predators....

Environmental variation favors the evolution of phenotypic plasticity. For many species, we understand the costs and benefits of different phenotypes, but we lack a broad understanding of how plastic traits evolve across large clades. Using identical experiments conducted across North America, we examined prey responses to predator cues. We quantified five life history traits and the magnitude of their plasticity for 23 amphibian species/populations (spanning three families and five genera) when exposed to no cues,...

Data from: Resurrected “ancient” Daphnia genotypes show reduced thermal stress tolerance compared to modern descendants

Understanding how populations adapt to rising temperatures has been a challenge in ecology. Research often evaluates multiple populations to test whether local adaptation to temperature regimes is occurring. Space-for-time substitutions are common, as temporal constraints limit our ability to observe evolutionary responses. We employed a resurrection ecology approach to understand how thermal tolerance has changed in a Daphnia pulicaria population over time. Temperatures experienced by the oldest genotypes were considerably lower than the youngest. We...

Data from: Biotic and abiotic factors shape the microbiota of wild-caught populations of the arbovirus vector Culicoides imicola

Biting midges of the genus Culicoides are known vectors of arboviruses affecting human and animal health. However, little is known about Culicoides imicola microbiota and its influence on this insect’s biology. In this study, the impact of biotic and abiotic factors on C. imicola microbiota was characterized using shotgun-metagenomic sequencing of whole body DNA samples. Wild-caught C. imicola adult nulliparous females were sampled in two locations from Sicily, Italy. The climatic variables of temperature and...

Data from: Predators buffer the effects of variation in prey nutrient content for nutrient deposition

Cody L. Barnes, Dror Hawlena & Shawn M. Wilder
Predator feeding behavior and digestion regulate the flow of nutrients through ecosystems by determining the fate of prey nutrients. Most predators feed on a diversity of prey items, which differ widely in traits including their nutrient content. Yet, relatively little is known of the mechanisms through which variation in prey nutrient content affects the form by which nutrients are deposited into the environment. The overall goal of this study was to test how variation in...

Data from: Development and validation of a weather-based warning system to advise fungicide applications to control dollar spot on turfgrass

Damon L. Smith, James P. Kerns, Nathan R. Walker, Andrea F. Payne, Brandon Horvath, John C. Inguagiato, John E. Kaminski, Maria Tomaso-Peterson & Paul L. Koch
Dollar spot is one of the most common diseases of golf course turfgrass and numerous fungicide applications are often required to provide adequate control. Weather-based disease warning systems have been developed to more accurately time fungicide applications; however, they tend to be ineffective and are not currently in widespread use. The primary objective of this research was to develop a new weather-based disease warning system to more accurately advise fungicide applications to control dollar spot...

Data from: Pyric herbivory, scales of heterogeneity, and drought

Christine H. Bielski, Dirac Twidwell, Samuel D. Fuhlendorf, Carissa L. Wonkka, Brady W. Allred, Tyson E. Ochsner, Erik S. Krueger, J. D. Carlson & David M. Engle
1. Understanding how extreme drought alters spatial patterns and temporal stability in grassland biomass will become increasingly important by the end of the century when climate model forecasts suggest drought events will occur more frequently. In grassland landscapes where grazing is driven by fire (termed pyric herbivory), temporal stability in aboveground plant biomass at landscape scales typically coincides with greater spatial variability across local communities (time-since fire patches), whereas variability within local communities is associated...
