Geographic variation in behavioral avoidance of a widespread contaminant by Gulf killifish Fundulus grandis

Charles W. Martin, Ashley M. McDonald, Kathryn A. O’Shaughnessy

Understanding the behavioral response of estuarine fishes to environmental contaminants is critical for assessing the ecological consequences of disturbances. Here, we examined geographic variation in avoidance behavior to petroleum-contaminated sediments in the Gulf killifish ( Fundulus grandis ), a sentinel species in …

Spatially limited influence of a Mississippi River freshwater diversion on estuarine nekton communities in coastal Louisiana ( U.S.A. )

Scott B. Alford, Charles W. Martin, Linda M Hooper-Bui, Olaf P. Jensen et autres

Abstract Introduction Freshwater diversions and marsh creation are prominent methods in coastal restoration, including in Louisiana (U.S.A.) where land loss rates rank among the highest in the world. However, concerns over impacts from altered salinity, including impacts on estuarine ecological structure and …

Effects of Seagrass-Mediated Soundscape Conservation on Fish Communities, Behaviors, and Communication Spaces

Audrey Looby, Mikayla Holloway, E.M. Lim, Kelsie A. Murchy et autres

Biogenic habitats are hypothesized to attenuate anthropogenic sounds—termed habitat-mediated soundscape conservation—with the potential to mitigate sound pollution impacts. This hypothesis was tested in seagrass meadows near Dangriga, Belize. Recreational boat sounds were reduced more at sites with denser habitats, with the site …

FishSounds Versions 2 and 3: Achieving the Largest Global Database of Fish Sound Production

Audrey Looby, Sarah Vela, Aaron N. Rice, Santiago Bravo et autres

ABSTRACT Motivation Fish sounds are integral to a variety of ecological functions, including reproduction, predator–prey interactions and recruitment, with ever‐growing interest in their relationships to anthropogenic impacts and applications for passive acoustic monitoring. Until recently, however, fish sound production data were often …

Habitat-mediated noise pollution reduction in seagrass meadows

Audrey Looby, Em G Lim, Kelsie A. Murchy, Laura K. Reynolds et autres

Despite widespread effects of anthropogenic noise on marine organisms, it is still unclear how the propagation of noise is influenced by habitat degradation. Here, we used field experiments to evaluate habitat-mediated reduction of noise pollution. We conducted habitat characterizations, faunal surveys, and …

Intraspecific Variation in Gulf Killifish ( Fundulus grandis ) Avoidance of Contaminants

Charles W. Martin, Ashley M. McDonald, Kathryn A. O’Shaughnessy

Abstract Understanding the behavioral response of estuarine fish populations to environmental contaminants is critical for assessing the ecological consequences of disturbances. Here, we examined population-level variation in avoidance behavior to petroleum-contaminated sediments in the Gulf killifish ( Fundulus grandis ), a sentinel …

Seagrass Species Identity Drives Leaf Litter Decomposition Across a Naturally Occurring Phosphorus Gradient

Alexandra L. Bijak, Ashley R. Smyth, Savanna C. Barry, Charles W. Martin et autres

Abstract Decomposition is one of several controls on carbon storage in seagrass meadows, but the relative importance of environmental conditions and seagrass species identity in driving decomposition is unclear. We first investigated direct environmental effects on decomposition by measuring percent mass lost …

Worldwide Soundscapes: A Synthesis of Passive Acoustic Monitoring Across Realms

Kevin Darras, Rodney Alan Rountree, Steven L. Van Wilgenburg, Anna F. Cord et autres

ABSTRACT Aim The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater and on land. However, we lack a unified methodology to report …

Temperature Drives Seagrass Recovery Across the Western North Atlantic

Fee O. H. Smulders, Justin E. Campbell, Andrew H. Altieri, Anna R. Armitage et autres

Climate-driven shifts in herbivores, temperature, and nutrient runoff threaten coastal ecosystem resilience. However, ecological resilience, particularly for foundation species, remains poorly understood due to the scarcity of field experiments conducted across appropriate spatial and temporal scales that investigate multiple stressors. This study …
