Adaptation in a Changing World: Evolutionary mechanisms of salt tolerance in a coastal amphibian
Albecker, Molly (East Carolina University, 2018-07-20)In order to predict evolutionary outcomes of environmental change on populations in nature, we need an improved understanding of the biological mechanisms that affect whether organisms will adapt to a changed environment. ... -
Adaptive responses to salinity stress across multiple life stages in anuran amphibians
Albecker, Molly; McCoy, Michael W. (2017-08-01)Background In many regions, freshwater wetlands are increasing in salinity at rates exceeding historic levels. Some freshwater organisms, like amphibians, may be able to adapt and persist in salt-contaminated wetlands by ... -
Brain size varies with temperature in vertebrates
Gillooly, James F.; McCoy, Michael W. (2014-03)The tremendous variation in brain size among vertebrates has long been thought to be related to differences in species’ metabolic rates. It is thought that species with higher metabolic rates can supply more energy to ... -
Climate Change Alters Trophic Interactions in Coastal Ecosystems
Speights, Cori J. (East Carolina University, 2016-05-04)Understanding the effects of multiple anthropogenic changes on local ecosystems is important for understanding community interactions. Because they lie at the interface between the land and sea coastal ecosystems are often ... -
The effects of elevated temperature and dissolved ρ CO 2 on a marine foundation species
Speights, Cori J.; Silliman, Brian R.; McCoy, Michael W. (2017-06)Understanding how climate change and other environmental stressors will affect spe- cies is a fundamental concern of modern ecology. Indeed, numerous studies have documented how climate stressors affect species distributions ... -

Influence of density and salinity on larval development of salt-adapted and salt-naïve frog populations
Albecker, Molly; Pahl, Matthew; Smith, Melanie; Wilson, Jefferson G.; McCoy, Michael W. (2020-01-08)Environmental change and habitat fragmentation will affect population densities for many species. For those species that have locally adapted to persist in changed or stressful habitats, it is uncertain how density ... -
INVESTIGATING THE EFFECTS OF LARVAL PHENOTYPES ON TRAITS EXHIBITED AT A CRUCIAL LIFE-HISTORY SWITCH POINT
Dormio, Samantha M. (East Carolina University, 2017-07-25)In organisms with complex life histories, phenotypes exhibited in non-reproductive life stages are often correlated with adult performance and fitness. For example, in anurans (frogs and toads), age and size at metamorphosis ... -
Life in a Contaminant Milieu: PPCP Mixtures Generate Unpredictable Outcomes Across Trophic Levels and Life Stages
Richards, Stephanie L.; Parrish, Samantha C.; Dormio, Samantha M.; McCoy, Krista A.; McCoy, Michael W. (2019-12-01) -
Life in a contaminant milieu: PPCP mixtures generate unpredictable outcomes across trophic levels and life stages
Parrish, Samantha C.; Dormio, Samantha M.; Richards, Stephanie L.; McCoy, Krista A.; McCoy, Michael W. (2019-12-05)Nearly all aquatic ecosystems are affected by sublethal levels of anthropogenic chemical contamination, but other agents of large‐scale anthropogenic disruption of ecosystems have received more attention. Consequently, ... -

A Method for Detecting Positive Growth Autocorrelation without Marking Individuals
Brooks, Mollie E.; McCoy, Michael W.; Bolker, Benjamin M. (2013-10-28)In most ecological studies, within-group variation is a nuisance that obscures patterns of interest and reduces statistical power. However, patterns of within-group variability often contain information about ecological ... -
Non-Linear Interactions between Consumers and Flow Determine the Probability of Plant Community Dominance on Maine Rocky Shores
Silliman, Brian R.; McCoy, Michael W.; Trussell, Geoffrey C.; Crain, Caitlin M.; Ewanchuk, Patrick J.; Bertness, Mark D. (2013)Although consumers can strongly influence community recovery from disturbance, few studies have explored the effects of consumer identity and density and how they may vary across abiotic gradients. On rocky shores in Maine, ... -

A practical guide and power analysis for GLMMs: detecting among treatment variation in random effects
Kain, Morgan P.; Bolker, Benjamin M.; McCoy, Michael W. (2015-09)In ecology and evolution generalized linear mixed models (GLMMs) are becoming increasingly used to test for differences in variation by treatment at multiple hierarchical levels. Yet, the specific sampling schemes that ... -
Prey Responses to Predator Chemical Cues: Disentangling the Importance of the Number and Biomass of Prey Consumed
McCoy, Michael W.; Touchon, Justin C.; Landberg, Tobias; Warkentin, Karen M.; Vonesh, James R. (2012)To effectively balance investment in predator defenses versus other traits, organisms must accurately assess predation risk. Chemical cues caused by predation events are indicators of risk for prey in a wide variety of ... -
Range expansion of a fouling species indirectly impacts local species interactions
Speights, Cori J.; McCoy, Michael W. (2017-10-19)We investigated how recent changes in the distribution and abundance of a fouling organism affected the strength of interactions between a commercially important foundation species and a common predator. Increases in the ... -

TEMPERATURE, RESOURCE INPUT, AND STANDING GENETIC VARIATION AFFECT PREDATOR RESPONSES OF PHYSA ACUTA
Gordon, Katherine E. (East Carolina University, 2019-04-26)In urban areas, features such as high percentages of impervious ground cover, patchiness, and storm water runoff can lead to increases in temperature and external nutrient input into aquatic systems. Such factors can lead ... -
