Behavioural Responses to Ultrasound Antifouling Systems by Adult Solitary Ascidians
نویسندگان
چکیده
Ultrasonic antifouling devices are installed globally on a variety of vessel types and marketed as an environmentally friendly method for biofouling control. The aim this study was to examine the effects ultrasound adults three species common solitary ascidians (Ciona intestinalis, Ascidiella aspersa Styela plicata). After brief (10 s) exposure two frequencies (30 35 kHz), alterations in frequency siphon closing events length time siphons remained closed/open were observed. results revealed that able perceive ultrasound, showing frequency-dependent behavioural responses vary depending size individuals involving both tactile receptors acoustic system homologous vertebrate inner ear. Continuous (5 h) 30 kHz caused other responses, most interesting which long-term opening oral siphon, indicating lack reactivity mechanical stimuli. This effect suggests stress condition could lead increased vulnerability predators filter-feeding impairment. Therefore, knowledge sensitivity sessile marine appears be essential better understanding potential noise pollution ecosystems.

Habitat niche breadth predicts invasiveness in solitary ascidians
A major focus of invasion biology is understanding the traits associated with introduction success. Most studies assess these traits in the invaded region, while only few compare nonindigenous species to the pool of potential invaders in their native region. We focused on the niche breadth hypothesis, commonly evoked but seldom tested, which states that generalist species are more likely to bec...
متن کاملBehavioural responses to cold thermal discomfort
Heating energy demand in buildings depends in part on occupants’ behavioural responses to thermal discomfort during the heating season. The understanding of this has become one of the priorities in the quest to reduce energy demand. Thermal comfort models have long been associated with occupants’ behaviour by predicting their state of thermal comfort or rather discomfort. These assumed that occ...
متن کاملMediastinal Solitary Fibrous Tumor Diagnosed by Endobronchial Ultrasound-Directed Biopsy
BACKGROUND Solitary fibrous tumors of the middle mediastinal space are uncommon and often not discovered until symptoms secondary to compression of adjacent structures occur. Diagnosis requires surgical biopsy and histological tissue analysis. We describe the ECHO appearance of the solitary fibrous tumor and successful non-invasive EBUS diagnosis. This method of diagnosis allowed for surgical p...
متن کاملVariable Structure Behavioural Controller for Multi-agent Systems
In previous papers authors have considered agents as inertia-less self driven particles and designed a flocking algorithm. Application of this algorithm to agents with considerable inertial characteristics needs a behavioural controller. The controller uses the local information and helps every agent to imitate the desired behaviour as a member of the flocking frame which covers the main is...
