Nonconsumptive effects in a multiple predator system reduce the foraging efficiency of a keystone predator
TLDR
The study suggests that the combined effect of multiple predators on prey can be better predicted when the influence of interactions between the CE and NCE of multiple predator species are incorporated into a predictive model. Expand
Partitioning the non-consumptive effects of predators on prey with complex life histories
TLDR
Comparing the effects of predator gape limitation and hunting mode on the activity, larval period, and size at metamorphosis of larval aquatic amphibians and invertebrates suggests NCEs on larval prey life history can be strongly influenced by predator functional characteristics. Expand
Scattering of Sound by Air Bubbles in Water
The scattering strength of air bubbles in water has been determined experimentally at frequencies of 1 and 5 MHz. The bubble size and sound frequencies represent the short wavelength limit, where kaExpand
Reevaluating geographic variation in life-history traits of a widespread Nearctic amphibian
TLDR
Body size, clutch size, and ovum size decreased in cold climates and at higher latitudes, suggesting selection for a life-history traits that favors maximizing propagule number over propagule size in coldClimate change, it is important to identify the limits of adaptation. Expand
Does dispersal influence the strength of intraspecific competition in a stream salamander
TLDR
The importance of integrating natural rates of dispersal into mechanistic experiments to understand spatial variability in the strength of intra- and interspecific species interactions is highlighted, as this first time that spatial sorting has been explicitly identified as contributing to thestrength of intraspecific interactions.

Acoustic Resonance Phenomena in Low Wattage Metal Halide Lamps
Computations of the acoustic frequencies and mode shapes were performed for small discharge lamps—about 6mm diameter, 30 Watts power. The effects of realistic temperature profiles and of electrodesExpand
Evaluating the effects of trophic complexity on a keystone predator by disassembling a partial intraguild predation food web.
TLDR
The study indicates that the effects of food web simplification on the performance of A. opacum are complex and depend on both how a partial IGP food web is simplified and how abundant prey are in the food web. Expand
Increasing conspecific density weakens the ability of intermediate predators to develop induced morphological defences to top predators
TLDR
This study demonstrates that top predators can induce phenotypes in intermediate predators that reduce their vulnerability to top predators while not compromising their ability to feed on a common prey. Expand
Batrachochytrium salamandrivorans (Bsal) not detected in an intensive survey of wild North American amphibians
TLDR
Modeling indicates that Bsal is highly unlikely to occur within wild amphibians in the U.S. and suggests that the best proactive response is to continue mitigation efforts against the introduction and establishment of the disease and to develop plans to reduce impacts should Bsal establish. Expand
Elevated temperatures alter competitive outcomes and body condition in southern Appalachian salamanders
TLDR
It is demonstrated that processes in size-structured communities may interact with temperature to affect species’ future success and individuals at future temperatures prioritized growth differently than individuals at current temperatures by shifting allocations away from growth in length to growth in mass.
