“…levels were measured at the start (120 -130 %) and end (112-120 %) of each trial to ensure that individuals were not exposed to hypoxic 185 conditions. Cardiac activity was recorded using an infrared phototransducer attached to the carapace using cyanoacrylate glue to facilitate heart rate monitoring using the ComputerAided Physiological MONitoring system (CAPMON) (Depledge & Andersen 1990 …”

“…Following urine extraction, heart rate measurements were performed on shore crabs by use of the non-invasive CAPMON system (Depledge and Andersen, 1990). Heart rate measurements were performed on individuals in 2 L aquaria (using water collected from each site); sensors were glued to the carapace above the heart and, after 30 min acclimation, cardiac activity (at rest) was recorded for 30 min as (as employed previously by Dissanayake et al, 2008b).…”

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous pollutants of the marine environment, arising predominantly from petrochemical contamination and pyrogenic sources. A biomarker of PAH exposure was employed in a field study (South West, Spain) in both captured (indigenous) and deployed (caged) shore crabs (Carcinus maenas) in the chronic PAH-exposed Bays of Algeciras and Gibraltar (from associated harbour and boating activity) compared to a relatively "clean" site (Cadiz).Metabolite fluorescence was attributed to the following key priority PAH groups; naphthalenes (NAPs), pyrenes (PYRs) and benzo[a]pyrenes (BAPs). Temporal variability was assessed using deployed populations over an eight week period.Petrogenic and pyrogenic PAH contamination (as an indicator of the PAH type) was demonstrated using a ratio between FF BAP+PYR / FF NAP . Physiological assessments from deployed crabs demonstrated both physiological and cellular alterations as shown by reduced heart rates (at rest) and increased cellular stress in crabs from the PAH contaminated sites.

“…In order to minimise the complexity of this method, Depledge and Anderson [19] instead developed the photoplethysmographic technique for non-invasive monitoring of cardiac activity in arthopods, which is utilised in the present study. Through this method an IR light-emitting diode (LED) coupled axially with a phototransistor (CNY-70 reflex-optocoupler, Vishay Semiconductor GmbH) is used to measure movements of internal organs.…”
