Experiments were carried out to study the behavioural responses of the Antarctic omnivorous starfish Odontaster validus to the chemical signals produced by undamaged conspecifics. Tested starved animals displayed the ability to distinguish between fed and starved conspecifics. Effluents of starved conspecifics were mostly ignored by O. validus, although(More)
Effects of temperature rise (from 0 to +5°C) and salinity decline (from 34 to 30 psu) on vital biological functions of the Antarctic isopod Serolis polita were studied in laboratory experiments. Behavioural reactions to food odour, as well as righting responses and reburying in the sediments, were measured. Both temperature increase and salinity decline(More)
Experiments were carried out to study the behavioural and metabolic responses of the Antarctic sea star, Odontaster validus, to different concentration of food signals (glutamic acid, aspartic acid, glicyne, alanine, tyrosine and a mixture of 11 amino acids). Stimulus concentration increase caused a rise in both the percentage of reacting animals and in the(More)
Chemical cues released from dead or injured organisms constitute important signals informing nearby animals about a feeding possibility. The ability to detect the signal, evaluate its meaning and locate its source can help organisms to exploit food resources efficiently, which is especially important to animals living in environments with limited food(More)
Experiments were carried out to study the behavioural responses of the omnivorous Antarctic sea star Odontaster validus to natural food odour, several single amino acids and their mixtures. Starved sea stars responded to natural food stimulus by rapid rise of metabolic rate, locomotory activity directed towards signal source, cessation of movement after(More)

Any disruption of the lymphatic system, including vessels and nodes, precludes the mobilization of lymph, resulting in the accumulation of colloidal material in the intercellular spaces. This article outlines the lymphatic system development and anatomy, leg lymph composition and flow, and diagnostic approaches and treatment for various forms of primary and(More)
