valves of sessile cirripedes (rock barnacles) are, in every sense of the word, very important structures, and they differ extremely little even in different genera; but in the several species of one genus, Pyrgoma, these valves present a marvellous amount of diversification: the homologous valves in the different species being sometimes wholly unlike in shape; and the amount of variation in the individuals of several of the species is so great, that it is no exaggeration to state that the varieties differ more from each other in the characters of these important valves than do other species of distinct genera.
Another group of tambaquis (n=96) was exposed to the same EO concentrations reported above to determine the ventilatory frequency (VF) through sedation and deep anesthesia; this was obtained through a visual observation of 20 successive opercular
or buccal movements (ALVARENGA & VOLPATO, 1995).
Comparison of age estimates from scale, opercular
bone, otolith, vertebrae and dorsal fin ray in Labeo rohita (Hamilton), Catla catla (Hamilton) and Channa marulius (Hamilton).
In general, increase in swimming and opercular
movements and reversal cases were observed.
syndrome is a severe form of pseudobulbar palsy caused by bilateral anterior opercular
Number of opercular
movements min-1 of four fish in each aquarium was counted without moving them from aquarium Foraging as shown in Figure 1a and social behavior including aggression (fish bit another; Figure 1b), schooling (at least 4 fish swimming together; Figure 1c), and shoaling (3 fish swimming together; Figure 1d) were analyzed.
IV--surgical anaesthesia Reduction of opercular
beatment, absence of natatory motion.
Among these, the most significant papers and research interests are dysphagia rehabilitation in opercular
syndrome in patients with stroke, aortic atherosclerosis, inflammation and stroke, stroke incidence, gender differences and stroke, stroke in women, homocysteine and stroke, patent foramen ovale and stroke, Takatsubo cardiomyopathy and transient general amnesia, and cerebral vasculitis.
Antheridia consist of a basal cell, an annular cell, and an undivided asymmetrical opercular
