COMPARATIVE ANALYSIS OF SWIMBLADDER (DRUMMING) AND PECTORAL (STRIDULATION) SOUNDS IN THREE FAMILIES OF CATFISHES

ABSTRACT

Among teleosts, only representatives of several tropical catfish families have evolved two sonic organs: pectoral spines for stridulation and swimbladder drumming muscles. Pectoral mechanisms differ in relative size between pimelodids, mochokids and doradids, whereas swimbladder mechanisms exhibit differences in origin and insertion of extrinsic muscles. Differences in vocalization among families were investigated by comparing distress calls in air and underwater. High frequency broad-band pulsed sounds of similar duration were emitted during abduction of pectoral spines in all three families. Adduction sounds were similar to abduction signals in doradids, shorter and of lower sound pressure in mochokids, and totally lacking in pimelodids. Simultaneously or successively with pectoral sounds, low frequency harmonic drumming sounds were produced by representatives of two families. Drumming sounds were of similar intensity as stridulatory sounds in pimelodids, fainter in doradids, and not present in mochokids. Swimbladder sounds were frequency modulated and the fundamental frequency was similar in pimelodids and doradids. The ratio of stridulatory to drumming sound amplitude was higher in air than underwater in both doradids and one of the pimelodids. Also, overall duration of pectoral sounds, compared to swimbladder sounds, was longer in air than underwater in one doradid and pimelodid species. This first comparison of vocalization within one major teleost order demonstrates a wide variation in occurrence, duration, intensity and spectral content of sounds and indicates family- and species-specific as well as context- (receiver-) dependent patterns of vocalization.     

A new species of Aphis Linnaeus from Guangxi,China (Hemiptera,Aphididae), based on morphological characters and DNA sequences

A new species of the genus Aphis with stridulatory apparatus, Aphis gnetuma Qiao sp. n., feeding on Gnetum parvifolium which is a new host plant record for aphids from Guangxi, China is described. The new species is distinguished by a well-developed median frontal tubercle and body bearing white wax powder in life. The taxonomic position of this new species is supported by analysis results of COI and gnd genes. A key to Aphis species with stridulatory spines on the hind tibiae of apterous viviparous females is provided. The type specimens studied are deposited in the National Zoological Museum of China, Institute of Zoology, Chinese Academy of Sciences, Beijing, China.www.zoobank.org/urn:lsid:zoobank.org:act:BBB024DA-8454-4E22-8736-66ED92A3091B.

Abdominal ventilatory pattern in crickets depends on the stridulatory motor pattern

Abstract. Ventilatory motor patterns were recorded from abdominal muscles in crickets, Gryllus campestris L.and Teleogryllus commodus (Walker), at rest and during three types of stridulatory motor activity; calling, courtship and aggressive song.
Increases in ventilatory period were almost exclusively due to an increase of the pause between expiratory bursts, whereas abdominal ventilatory bursts remained constant at 200 ms.Ventilatory patterns depended on the stridulatory motor pattern and indicated that the same basic respiratory oscillator exists in both cricket species.
In G.campestris there was a strict 1:1 coupling between chirps and ventilatory bursts.In T.commodus such a relationship was also observed for the chirp part of the songs, but less strictly for the trill part of the calling song and not for the courtship song.In both species the onset of the ventilatory burst was within ± 100 ms of a stridulatory chirp.Ventilatory burst lasted longer the earlier they began before a stridulatory chirp.This suggests strongly that the stridulatory motor pattern terminates the expiratory burst, and thus influences the ventilatory motor pattern.
