Predator-prey interactions are important drivers in structuring ecological communities. However, despite widespread acknowledgement that individual behaviours and predator species regulate processes, studies have yet to incorporate behavioural variations a multipredator system. We quantified prevalent avoidance behaviour examine the simultaneous roles of prey personality hunting mode governing predator-prey interactions. Mud crabs, Panopeus herbstii, reduce their activity levels increase...

The physiological condition and fecundity of an organism is frequently controlled by diet. As changes in environmental conditions often cause organisms to alter their foraging behavior, a comprehensive understanding how diet influences the fitness individual central predicting effect change on population dynamics. We experimentally manipulated economically ecologically important blue crab, Callinectes sapidus, approximate effects dietary shift from primarily animal plant tissue, phenomenon...
Abstract Individual phenotypic differences are increasingly recognized as key drivers of ecological processes. However, studies examining the relative importance these in comparison with environmental factors or how individual phenotype interacts across different contexts remain lacking. We performed two field experiments to assess concurrent roles personality and habitat quality mediating mortality dispersal. quantified predator avoidance response mud crabs, Panopeus herbstii , collected...
Abstract The capacity of an apex predator to produce nonconsumptive effects (NCEs) in multiple prey trophic levels can create considerable complexity cascading interactions, but these are poorly studied. We examined such a model food web where the (blue crabs) releases chemical cues urine that affect both intermediate consumer (mud crabs seek shelter) and basal (oysters induced grow stronger shells). Shelter availability presence were manipulated laboratory experiment identify patterns...
The realized niche of many sessile intertidal organisms is constrained by different stressors that set boundaries for their distribution based on tidal elevation. Higher elevation increases desiccation risk but can provide a refuge from predation. Conversely, deeper water feeding time and growth also vulnerability to benthic predators. Eastern oysters Crassostrea virginica harden shells in response predator cues, which reduces mortality We performed field study investigate if this defense...
Hydrodynamic stress shapes the flora and fauna that exist in wave-swept environments, alters species interactions, can become primary community structuring agent. Yet, hydrodynamics be difficult to quantify because instrumentation is expensive, some methods are unreliable, accurately measuring spatial temporal differences difficult. Here, we explored utility of barnacles as potential biological flow-indicators. Barnacles, nearly ubiquitous within estuarine have demonstrated notable...
Seagrass meadows provide greater predator refuge and resource availability than unvegetated habitats generally improve the survival growth rates of associated animals. Few studies, however, have examined how these relationships might vary at a region-wide spatial scale. The blue crab Callinectes sapidus is commercially important species that uses turtlegrass Thalassia testudinum habitats, but it unclear if use seagrass varies across northern Gulf Mexico (GOM), USA. We conducted synoptic...
Drift macroalgae, often found in clumps or mats adjacent to within seagrass beds, can increase the value of beds as habitat for nekton via added food resources and structural complexity. But, algal biomass increases, it also decrease light availability, inhibit faunal movements, smother benthic communities, contribute hypoxia, all which reduce abundance. We quantified abundance distribution drift macroalgae meadows dominated by turtle grass Thalassia testudinum across northern Gulf Mexico...
Drift macroalgae, often found in clumps or mats adjacent to within seagrass beds, can provide additional food resources and habitat complexity, leading increased animal abundance, but large concentrations also inhibit faunal movements, smother benthic communities, contribute hypoxia, reducing nekton abundance. Despite its ubiquity, few studies have quantified drift macroalgal prevalence over spatial scales effects on seagrass-associated nekton, hindering our understanding of the functional...
