Data from: Evaluating consumptive and nonconsumptive predator effects on prey density using field times series data

, Scott D. Peacor, David B. Bunnell, Henry A. Vanderploeg, Steve A. Pothoven, Ashley K. Elgin, James R. Bence, Jing Jiao, Edward L. Ionides, D.B. Bunnell, J.A. Marino, E.L. Ionides, S.A. Pothoven, A.K. Elgin, H.A. Vanderploeg, S.D. Peacor & J.R. Bence
Determining the degree to which predation affects prey abundance in natural communities constitutes a key goal of ecological research. Predators can affect prey through both consumptive effects (CEs) and nonconsumptive effects (NCEs), although the contributions of each mechanism to the density of prey populations remain largely hypothetical in most systems. Common statistical methods applied to time series data cannot elucidate the mechanisms responsible for hypothesized predator effects on prey density (e.g., differentiate CEs from NCEs),...

Data from: Evaluation of acoustic telemetry grids for determining aquatic animal movement and survival

1. Acoustic telemetry studies have frequently prioritized linear configurations of hydrophone receivers, such as perpendicular from shorelines or across rivers, to detect the presence of tagged aquatic animals. This approach introduces unknown bias when receivers are stationed for convenience at geographic bottlenecks (e.g., at the mouth of an embayment or between islands) as opposed to deployments following a statistical sampling design. 2. We evaluated two-dimensional acoustic receiver arrays (grids: receivers spread uniformly across space) as...

Data from: A simple, cost-effective emitter for controlled release of fish pheromones: development, testing, and application to management of the invasive sea lamprey

C. Michael Wagner, James E. Hanson, Trevor D. Meckley, Nicholas S. Johnson & Jason D. Bals
Semiochemicals that elicit species-specific attraction or repulsion have proven useful in the management of terrestrial pests and hold considerable promise for control of nuisance aquatic species, particularly invasive fishes. Because aquatic ecosystems are typically large and open, use of a semiochemical to control a spatially dispersed invader will require the development of a cost-effective emitter that is easy to produce, environmentally benign, inexpensive, and controls the release of the semiochemical without altering its structure. We...

Data from: Is barotrauma an important factor in the discard mortality of yellow perch?

Carey T. Knight, Richard T. Kraus, Demetra A. Panos, Ann Marie Gorman, Benjamin S. Leonhardt, Jason Robinson & Michael Thomas
In physoclistous fishes, barotrauma caused by rapid decompression during capture may be an important source of fishing mortality that is unquantified for some fisheries. We developed a predictive logistic model for barotrauma incidence in Yellow Perch Perca flavescens and applied this model to Ohio's recreational and commercial fisheries in Lake Erie where discard mortality is implicitly considered to be negligible in current stock assessment. As expected, most of the variation in incidence was explained by...
