Productivity change and fleet restructuring after transition to individual transferable quota management

Creator:: Färe, Rolf, Grosskopf, Shawna, and Walden, John
Abstract:: Productivity change after transition to an individual transferable quota (ITQ) management system is driven by exit of some vessels, entry of other vessels, and changes in productivity of existing vessels. Generally, it is thought that an ITQ system boosts productivity due to the exit of less productive vessels. However, ITQ...

Conditions favouring Bromus tectorum dominance of endangered sagebrush steppe ecosystems

Creator:: Reisner, Michael D., Grace, James B., Pyke, David A., and Doescher, Paul S.
Abstract:: 1. Ecosystem invasibility is determined by combinations of environmental variables, invader attributes, disturbance regimes, competitive abilities of resident species and evolutionary history between residents and disturbance regimes. Understanding the relative importance of each factor is critical to limiting future invasions and restoring ecosystems. 2. We investigated factors potentially controlling Bromus...

Integrating occupancy models and structural equation models to understand species occurrence

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...

Glacial ocean overturning intensified by tidal mixing in a global circulation model

Creator:: Schmittner, A., Green, J. A. M., and Wilmes, S. -B.
Abstract:: Due to lower sea levels during the Last Glacial Maximum (LGM), tidal energy dissipation was shifted from the shallow margins into the deep ocean. Here using a high-resolution tide model, we estimate that global energy fluxes below 200 m depth were almost quadrupled during the LGM. Applying the energy fluxes to...

Past tree influence and prescribed fire mediate bioticinteractions and community reassembly in agrassland-restoration experiment

Creator:: Halpern, Charles B., Antos, Joseph A., McKenzie, Donald, and Olson, Annette M.
Abstract:: Summary 1. Woody plant encroachment of grasslands is occurring globally, with profound ecological consequences. Attempts to restore herbaceous dominance may fail if the woody state is resilient or if intervention leads to an alternate, undesirable state. Restoration outcomes often hinge on biotic interactions – particularly on priority effects that inhibit...

Resource waves: phenological diversity enhances foraging opportunities for mobile consumers

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...

A climate of uncertainty: accounting for error in climate variables for species distribution models

Creator:: Stoklosa, Jakub, Daly, Christopher, Foster, Scott D., Ashcroft, Michael B., and Warton, David I.
Abstract:: 1. Spatial climate variables are routinely used in species distribution models (SDMs) without accounting for the fact that they have been predicted with uncertainty, which can lead to biased estimates, erroneous inference and poor performances when predicting to new settings – for example under climate change scenarios. 2. We show...

Use of Multidetector Computed Tomography in the Assessment of Dogs with Pericardial Effusion

Creator:: Scollan, K. F., Bottorff, B., Stieger-Vanegas, S., Nemanic, S., and Sisson, D.
Abstract:: Background: Contrast-enhanced multidetector computed tomography ( MDCT) allows high spatial and temporal resolution imaging of cardiac, thoracic, and abdominal structures. Accurate determination of the cause of pericardial effusion ( PE) is essential to providing appropriate treatment and prognosis. Echocardiography and pericardial fluid analysis may not differentiate between causes of PE...

Changing forest water yields in response to climate warming: results from long-term experimental watershed sites across North America

Creator:: Creed, Irena F., Spargo, Adam T., Jones, Julia A., Buttle, Jim M., Adams, Mary B., Beall, Fred D., Booth, Eric G., Campbell, John L., Clow, Dave, Elder, Kelly, Green, Mark B., Grimm, Nancy B., Miniat, Chelcy, Ramlal, Patricia, Saha, Amartya, Sebestyen, Stephen, Spittlehouse, Dave, Sterling, Shannon, Williams, Mark W., Winkler, Rita, and Yao, Huaxia
Abstract:: Climate warming is projected to affect forest water yields but the effects are expected to vary. We investigated how forest type and age affect water yield resilience to climate warming. To answer this question, we examined the variability in historical water yields at long‐term experimental catchments across Canada and the...

Characterizing seawater oxygen isotopic variability in a regional ocean modeling framework: Implications for coral proxy records

Creator:: Stevenson, S., Powell, B. S., Merrifield, M. A., Cobb, K. M., Nusbaumer, J., and Noone, D.
Abstract:: Reconstructions of the El Niño–Southern Oscillation (ENSO) are often created using the oxygen isotopic ratio in tropical coral skeletons (δ¹⁸O). However, coral δ¹⁸O can be difficult to interpret quantitatively, as it reflects changes in both temperature and the δ¹⁸O value of seawater. Small-scale (10–100 km) processes affecting local temperature and...
