Creator:: Joseph, Maxwell B., Preston, Daniel Lucas, and Johnson, Pieter T. J.
Abstract:: Understanding the drivers of species occurrence is a fundamental goal in basic and applied ecology. Occupancy models have emerged as a popular approach for inferring species occurrence because they account for problems associated with imperfect detection in field surveys. Current models, however, are limited because they assume covariates are independent...

Abstract:: With many ecosystems now supporting multiple nonnative species from different trophic levels, it can be challenging to disentangle the net effects of invaders within a community context. Here, we combined wetland surveys with a mesocosm experiment to examine the individual and combined effects of nonnative fish predators and nonnative bullfrogs...

Creator:: Armstrong, Jonathan B., Takimoto, Gaku, Schindler, Daniel E., Hayes, Matthew M., and Kauffman, Matthew J.
Abstract:: Time can be a limiting constraint for consumers, particularly when resource phenology mediates foraging opportunity. Though a large body of research has explored how resource phenology influences trophic interactions, this work has focused on the topics of trophic mismatch or predator swamping, which typically occur over short periods, at small...

Creator:: Goetz, Scott J., Steinberg, Daniel, Betts, Matthew G., Holmes, Richard T., Doran, Patrick J., Dubayah, Ralph, and Hofton, Michelle
Abstract:: A topic of recurring interest in ecological research is the degree to which vegetation structure influences the distribution and abundance of species. Here we test the applicability of remote sensing, particularly novel use of waveform lidar measurements, for quantifying the habitat heterogeneity of a contiguous northern hardwoods forest in the...

Creator:: Preston, Daniel L., Henderson, Jeremy S., Falke, Landon P., Segui, Leah M., Layden, Tamara J., and Novak, Mark
Abstract:: Describing the mechanisms that drive variation in species interaction strengths is central to understanding, predicting, and managing community dynamics. Multiple factors have been linked to trophic interaction strength variation, including species densities, species traits, and abiotic factors. Yet most empirical tests of the relative roles of multiple mechanisms that drive...

Creator:: Zarnetske, Phoebe L., Hacker, Sally D., Seabloom, Eric W., Ruggiero, Peter, Killian, Jason R., Maddux, Timothy B., and Cox, Daniel
Abstract:: Vegetation at the aquatic–terrestrial interface can alter landscape features through its growth and interactions with sediment and fluids. Even similar species may impart different effects due to variation in their interactions and feedbacks with the environment. Consequently, replacement of one engineering species by another can cause significant change in the...

Creator:: Bond, Morgan H. and Miller, Jessica A.
Abstract:: Across animal taxa, migration allows individuals to exploit habitats and resources that predictably vary seasonally in suitability. Theory predicts that the ‘‘decision’’ to migrate or not is shaped by the relative fitness costs and benefits of exhibiting a given life history. Adoption of a migratory strategy is widely thought to...
