2009 journal article

Environmental and Physiological Controls of Blue Crab Avoidance Behavior During Exposure to Hypoxia

BIOLOGICAL BULLETIN, 217(2), 161–172.

By: G. Bell n, D. Eggleston n  & E. Noga n

MeSH headings : Animals; Avoidance Learning; Behavior / drug effects; Brachyura / physiology; Hypoxia; Locomotion; Stress, Physiological
TL;DR: Blue crabs that had hemocyanin structures with a high affinity for O2 (hypoxia-tolerant) were less active under hypoxic conditions than conspecifics with hemOCyanins with a low O2 affinity, suggesting that physiological state influences behavioral responses to stressors.

2005 journal article

Interactive effects of episodic hypoxia and cannibalism on juvenile blue crab mortality

JOURNAL OF EXPERIMENTAL MARINE BIOLOGY AND ECOLOGY, 325(1), 18–26.

By: D. Eggleston n , G. Bell n & A. Amavisca n

author keywords: blue crab; hypoxia; indirect effects; predation; tethering; trophic interactions
TL;DR: Blue blue crabs may be relatively safe from adult conspecifics during hypoxic upwelling events, but not during chronic hypoxia, which highlights the need to consider the effects of dynamic water quality on mobile consumers emigrating from degraded habitats when considering indirect trophic impacts beyond the immediate area of impact.

2004 journal article

Species-specific avoidance responses by blue crabs and fish to chronic and episodic hypoxia

MARINE BIOLOGY, 146(4), 761–770.

By: G. Bell n & D. Eggleston n 

TL;DR: All taxa showed a stronger avoidance response to chronic hypoxia as compared to episodic hypoxic upwelling events, and the two taxa most closely associated with the bottom (blue crabs and flounder) showed the strongest avoidance response. (via Semantic Scholar)

2003 journal article

Behavioral responses of free-ranging blue crabs to episodic hypoxia. I. Movement

MARINE ECOLOGY PROGRESS SERIES, 259(2003), 215–225.

By: G. Bell n, D. Eggleston n  & T. Wolcott n

author keywords: avoidance behavior; hypoxia; movement; biotelemetry; blue crab; Callinectes sapidus; orientation; upwelling; Neuse River Estuary; estuary
TL;DR: It is suggested that crabs may have fed on prey other than benthic infauna, or that upwelling events may not have lasted long enough to cause infauna to migrate close enough to the sediment surface to be vulnerable to predation by blue crabs. (via Semantic Scholar)
