In Silico Polymorphism

Historically, many population genetics studies have utilized microsatellite markers sampled at random from the genome and presumed to be selectively neutral. Recent studies, however, have shown that microsatellites can occur in transcribed regions, where they are more likely to be under selection. In this study, we mined microsatellites from transcriptomes generated by 454-pyrosequencing for three vertebrate species: lake sturgeon (Acipenser fulvescens), tiger salamander (Ambystoma tigrinum), and kangaroo rat (Dipodomys spectabilis). We evaluated (i) the occurrence of microsatellites across species; (ii) whether particular gene ontology terms were over-represented in genes that contained microsatellites; (iii) whether repeat motifs were located in untranslated regions or coding sequences of genes; and (iv) in silico polymorphism. Microsatellites were less common in tiger salamanders than in either lake sturgeon or kangaroo rats. Across libraries, trinucleotides were found more frequently than any other motif type, presumably because they do not cause frameshift mutations. By evaluating variation across reads assembled to a given contig, we were able to identify repeat motifs likely to be polymorphic. Our study represents one of the first comparative data sets on the distribution of vertebrate microsatellites within expressed genes. Our results reinforce the idea that microsatellites do not always occur in noncoding DNA, but commonly occur in expressed genes.

AbstractThe descriptions of pupae of three Western Palaearctic species of Erebidae (subfamily Herminiinae), namely Idia calvaria (Denis et Schiffermüller, 1775), Pechipogo flavicrinalis (Andreas, 1910), and Nodaria nodosalis (Herrich-Schäffer, 1851), and three species of Noctuidae (subfamilies Acronictinae and Bryophilinae), namely Oxicesta geographica (F., 1787), Simyra dentinosa (Freyer, 1839), and Cryphia ochsi Boursin, 1940 are given. The main morphological features are described, compared with those of the related taxa and also illustrated in 57 line drawings. The systematic status and position of the described species present in the current systems are also discussed from the point of view of morphology of their pupae.

A New Species

Forty-one specimens of the pontoniine shrimp genus Periclimenaeus Borradaile, 1915, from the Hawaiian region, collected between 1923 and 1937 and reported on by Charles H. Edmondson, have been re-examined. Thirty-seven are provisionally referred to P. quadridentatus (Rathbun, 1906) and two are described and illustrated as P. edmondsoni sp. nov. The systematic status of P. quadridentatus (Rathbun, 1906) and P. stylirostris Bruce, 1969, is discussed and P. marini, from Vietnam, is designated as a new species.

Thermoregulatory System

Unanesthetized, unrestrained kangaroo rats (Dipodomys) were studied to examine the changes in the frequency and duration of sleep states caused by long-term manipulations of hypothalamic temperature (Thy) at a thermoneutral (30 degrees C) and a low (20 degrees C) ambient temperature (Ta). A cold stimulus present in either the hypothalamus or the skin decreased both the total sleep time (TST) and the ratio of paradoxical sleep (PS) to TST. At a low Ta, TST, but not the PS-to-TST ratio, was increased by raising Thy, indicating that a cold peripheral stimulus could differentially inhibit PS. At a thermoneutral Ta, cooling Thy decreased both TST and the PS/TST. Changes in the amount of PS were due largely to changes in the frequency, but not the duration, of individual episodes of PS, suggesting that the transition to PS is partially dependent on the thermoregulatory conditions existing during slow-wave sleep (SWS). These results are consistent with the recent findings that the thermoregulatory system is functional during SWS but is inhibited or inactivated during PS.
