James W. Cain III, Jay V. Gedir, Jason P. Marshal, Paul R. Krausman, Jamison D. Allen, Glenn C. Duff, Brian Jansen, John R. Morgart
2017, Oikos (126) 1459-1471
Nutritional ecology forms the interface between environmental variability and large herbivore behaviour, life history characteristics, and population dynamics. Forage conditions in arid and semi-arid regions are driven by unpredictable spatial and temporal patterns in rainfall. Diet selection by herbivores should be directed towards overcoming the most pressing nutritional limitation (i.e....

Resilience in ecotoxicology: Toward a multiple equilibrium concept
Mirco Bundschuh, Ralf Schulz, Craig R. Allen, David G. Angeler
2017, Environmental Toxicology and Chemistry (36) 2574-2580
The term resilience describes stress–response patterns across scientific disciplines. In ecology, advances have been made to clearly define resilience based on underlying mechanistic assumptions. Engineering resilience (rebound) is used to describe the ability of organisms to recover from adverse conditions (disturbances), which is termed the rate of recovery. By contrast,...

Eli G. Lampo, Brent C. Knights, Jonathan M. Vallazza, Cory A. Anderson, Will T. Rechkemmer, Levi E. Solomon, Andrew F. Casper, Richard M. Pendleton, James T. Lamer
2017, North American Journal of Fisheries Management (37) 1145-1150
The Silver Carp Hypophthalmichthys molitrix is an invasive species in the Mississippi River basin; an understanding of their vulnerability to predation as juveniles may inform control by native predators and predator enhancement (e.g., stocking). Digestion of Silver Carp prey recovered from diets makes it difficult to determine the size‐classes that are most...
Compositional signatures in acoustic backscatter over vegetated and unvegetated mixed sand-gravel riverbeds
Daniel D. Buscombe, Paul E. Grams, Matthew A. Kaplinski
2017, Journal of Geophysical Research F: Earth Surface (122) 1771-1793
Multibeam acoustic backscatter has considerable utility for remote characterization of spatially heterogeneous bed sediment composition over vegetated and unvegetated riverbeds of mixed sand and gravel. However, the use of high-frequency, decimeter-resolution acoustic backscatter for sediment classification in shallow water is hampered by significant topographic contamination of the signal. In mixed...

2017, Ecology and Society (22) 1-15
Adaptive governance must work “on the ground,” that is, it must operate through structures and procedures that the people it governs perceive to be legitimate and fair, as well as incorporating processes and substantive goals that are effective in allowing social-ecological systems (SESs) to adapt to climate change and other...
Accounting for imperfect detection of groups and individuals when estimating abundance
Matthew J. Clement, Sarah J. Converse, J. Andrew Royle
2017, Ecology and Evolution (7) 7304-7310
If animals are independently detected during surveys, many methods exist for estimating animal abundance despite detection probabilities <1. Common estimators include double-observer models, distance sampling models and combined double-observer and distance sampling models (known as mark-recapture-distance-sampling models; MRDS). When animals reside in groups, however, the assumption of independent detection is...

2017, Report, The state of Lake Ontario in 2014
Lake Ontario’s nearshore fish community consists of a diverse assemblage of warm- and cool-water species. The “nearshore zone,” loosely separated from the “offshore zones” by the 15-m depth contour, consists of complex habitats spanning a gamut from vast open-coastal areas to sheltered embayments and wetlands. Lake Ontario’s nearshore habitat has...
Diet composition, quality and overlap of sympatric American pronghorn and gemsbok
James W. Cain III, Mindi M. Avery, Colleen A. Caldwell, Laurie B. Abbott, Jerry L. Holechek
2017, Wildlife Biology (2017) 1-10
Species with a long evolutionary history of sympatry often have mechanisms for resource partitioning that reduce competition. However, introduced non-native ungulates often compete with native ungulates and competitive effects can be exacerbated in arid regions due to low primary productivity. Our objectives were to characterize diet composition, quality, and overlap...

David Deslauriers, Alex J. Rosburg, Steven R. Chipps
2017, Canadian Journal of Fisheries and Aquatic Sciences (74) 1668-1681
We developed a foraging model for young fishes that incorporates handling and digestion rate to estimate daily food consumption. Feeding trials were used to quantify functional feeding response, satiation, and gut evacuation rate. Once parameterized, the foraging model was then applied to evaluate effects of prey type, prey density, water...
