Copy Number Variation has been associated with morphological traits, developmental defects or disease susceptibility. The autosomal dominant Pea-comb mutation in chickens is due to the massive amplification of a CNV in intron 1 of SOX5 and provides a unique opportunity to assess the effect of variation in the number of repeats on quantitative traits such as comb size and comb mass in Pea-comb c...

The bryozoan genus Scrupocellaria comprises about 80 species in the family Candidae. We propose a hypothesis for the phylogenetic relationships among species assigned to Scrupocellaria to serve as framework for a phylogenetic classification using 35 morphological characters. Our results suggest that the genus Scrupocellaria is polyphyletic. Scrupocellaria s. str. is redefined according to four ...

Rose-comb, a classical monogenic trait of chickens, is characterized by a drastically altered comb morphology compared to the single-combed wild-type. Here we show that Rose-comb is caused by a 7.4 Mb inversion on chromosome 7 and that a second Rose-comb allele arose by unequal crossing over between a Rose-comb and wild-type chromosome. The comb phenotype is caused by the relocalization of the ...

Comb method is an efficient method to calculate point multiplication in elliptic curve cryptography, but vulnerable to power-analysis attacks. Various algorithms have been proposed recently to make the comb method secure to power-analysis attacks. In this paper, we present an efficient comb method and its Simple Power Analysis (SPA)-resistant counterpart. We first present a novel comb recoding ...

a study was carried out to evaluate the secondary sexual characteristics of four strains of cocks, comprising of two (2) exotics; bovan nera black (bnb) and isa brown (isb), one (1) improved local strain, shika brown (sb) and one (1) unimproved local strain, normal feathered cock (nfc). a total of 64 birds (16 for each strain) at 36, 38, 40 and 42 weeks were used for the study. the result indic...

Accurate fossil identification has become increasingly relevant with the widespread use of phylogenetic divergence time estimation methods, which rely on fossil data to determine clade hard-minimum ages. Here we revise, diagnose and illustrate known spider wasp (Hymenoptera: Pompilidae) fossil species and place them within the latest Pompilidae phylogenetic hypothesis. Ceropalites infelix Cocke...

Zwicknia Murányi, gen. n. is erected for the Capnia bifrons species group sensu Zhiltzova, 2001 with the description of three new species based on morphology, mating call, and the mitochondrial DNA marker cytochrome c oxidase I: Z. acuta Murányi & Orci, sp. n., Z. kovacsi Murányi & Gamboa, sp. n. and Z. rupprechti Murányi, Orci & Gamboa, sp. n.. Zwicknia bifrons (Newman, 1838) comb. n. is selec...

Phylogeny of Polycentropodidae Ulmer is inferred based on data from immature and adult stages. Larval information is unknown for 61% of the taxa included in this study. To understand the effects of including characters with large sets of missing data, three alternative datasets were analysed using parsimony and Bayesian methods. Five outgroup taxa, including the four families in Psychomyioidea ...

Following the recent reclassification of the Palaeotropic xyleborine genera (Hulcr and Cognato in press), additional species are transferred to correct genera or synonymized based on analysis of their morphological characters. The following species are given new combinations: Debus amphicranoides (Hagedorn), comb. n., Debus birmanus (Eggers, 1930), comb. n., Debus dolosus (Blandford, 1896), com...

Thirty-five species of the genus Houghia Coquillett (Tachinidae, Exoristinae, Goniini) are described, 34 new and one previously described, all reared from -various species of caterpillars collected in Area de Conservación Guanacaste (ACG), northwestern Costa Rica. A matrix of character states and a key for the identification of the species are also provided. By coupling morphology, life history...
