Measurement of physiological condition of mussels transplanted along a pollution gradient in Narragansett Bay

Differences in feeding adaptations in intertidal and subtidal suspension-feeding gastropods: studies on Crepidula fornicata and Crepipatella peruviana

“…However, our experiments were performed at cooler temperatures than in Chaparro et al (2002), and C. peruviana in our study were first removed from their substrates and transferred to plastic plates, both of which may have contributed to the slower particle velocities that we found. The intertidal zone is a particularly stressful place to live (e.g., Brinkhoff et al 1983;Morris and Taylor 1983;Garrity 1984;Petes et al 2007;Harley et al 2009;Miller et al 2009;Diederich and Pechenik 2013) for sedentary marine organisms, and physiological stress has previously been associated with reduced performance (i.e., feeding rate) in some marine invertebrates (Abel 1976;Menge 1978;Widdows et al 1981;McCormick et al 1998). The pattern of CR and particle velocity transport across the gill in addition to the pattern of size distribution (subtidal > intertidal) in C. peruviana suggests that intertidal individuals could be stressed in relatively poor physiological condition.…”

Effect of field exposure to 38-year-old residual petroleum hydrocarbons on growth, condition index, and filtration rate of the ribbed mussel, Geukensia demissa

“…Through filtering large quantities of water, mussels are exposed to lipophilic PAHs, which are known to bioconcentrate by 2-5 orders of magnitude within mussel tissue (Neff 2002). This exposure to hydrocarbons can decrease population (Peteiro et al, 2006) and individual growth rates (Stromgren et al, 1986;LeFloch et al, 2003), lower condition indices (Bayne and Worrall, 1980), and lower feeding rates (clearance rates) (Widdows et al, 1981;Widdows et al, 1987;Widdows et al, 1996)..…”

“…The use of mussel transplant experiments has been critical in the examination of effects from petroleum contamination in coastal environments (Widdows et al, 1981;Cheung et al, 2001;Honkoop et al, 2003;Peteiro et al, 2006 …”

Influence of temperature and food availability on the ecological energetics of the giant scallop Placopecten magellanicus. I. Growth rates of shell and somatic tissue

“…Growth rate and reproductive output are good indicators of the suitability of the environment, as they represent the integrated response of physiological activities in the organism. The approach often adopted has been to compare animals collected along some presumed or measured gradient of environmental quality, including the intertidal zone (Griffiths 1981a), latitudinally separated areas (Barber & Blake 1983), various water depths (Kautsky 1982a, b, Rodhouse et al 1984 and different types of habitat (Bayne & Worrail 1980) including polluted areas (Widdows et al 1981).…”
