Previously referred to as Boophis sp. 1 (aff. ankaratra) (Andreone et al. 2007), Boophis aff. ankaratra ‘Antoetra slow’ (Glaw & Vences 2007), and Boophis sp. 18 (Vieites et al. 2009). Holotype (Figs. 2–3 A). KU 336824, an adult male collected by Carl R. Hutter and Zo F. Andriampenomanana on 18 January 2014, at Maharira within Ranomafana National Park (21 ° 20 '06.3"S, 47 ° 24 ' 28.31 "E; 1233 m, above sea level [a.s.l.]), Fianarantsoa province, Madagascar. Paratypes. Adult female KU 336829 and adult male KU 336826 collected on 21 January 2013 by Carl R. Hutter and Shea M. Lambert with same locality data as holotype. Adult males KU 336828, KU 336825, KU 336827, with same collection data as holotype. Referred specimens. UADBA-Uncatalogued (CRH 080), UADBA-Uncatalogued (CRH 168), UADBA- Uncatalogued (CRH 178) with same collection data as holotype. Etymology. This species in named in honor of Nicholas Jay Pritzker, devoted grandfather, father and husband, brilliant businessman, philanthropist, amateur scientist, committed conservationist; and board member, supporter and long-time friend of Conservation International. The name ‘Boppa’ is an affectionate nickname used by his children and grandchildren. This dedication is courtesy of his youngest son Isaac, who has generously supported amphibian research in Madagascar, including this study and future taxonomic research as well. The species name is used as an invariable noun in apposition to the genus name. Diagnosis. Boophis boppa (Figs. 2–4) is placed in the family Mantellidae, subfamily Boophinae, and genus Boophis, as diagnosed by Glaw & Vences (2006). The new species shares the following combination of morphological traits with all other Boophis: presence of intercalary element between ultimate and penultimate phalanges of fingers and toes; presence of nuptial pads and absence of femoral glands in males; absence of gular glands in males; terminal discs of fingers and toes enlarged; lateral metatarsalia separated by webbing; and absence of outer metatarsal tubercle. Furthermore, phylogenetic analyses support the placement of the new species in the genus Boophis. Boophis boppa is placed in the Boophis albipunctatus group as supported by the phylogenetic analyses. Additionally, the following combination of characters provide additional evidence for the inferred phylogenetic relationships: small body size (male SVL 90 %; PP> 0.95; Fig. 8). Uncorrected p-distances using the 16 S fragment indicate that B. ankaratra has the lowest distance to the new species, at 1.9–3.7 %. Additionally, we find that variation in genetic distance among B. boppa and B. ankaratra is not related to geographic proximity. The lowest distance of 1.9 % (Imaitso Forest; FMGV 1697) does not correspond to proximate localities and the highest distance of 3.7 % is from Ranomafana National Park (Ranomena; ZCMV 5989). This variability in distances is likely a result of varying amounts of sequence overlap being compared. Overall, these results provide strong evidence that the species is a separately evolving lineage and does not reproduce with other species in the complex. Distribution (Fig. 1). Boophis boppa is known from Ranomafana National Park (RNP), but has only been found at high elevation sites (~ 1046–1312 m, a.s.l.). In addition to the type locality of Maharira, DNA sequences also confirm that specimens FAZC 11454, 11462, and 11480 collected from Farihimazava forest near Antoetra (20 ° 50 '06"S, 47 ° 19 ' 57 "E, 1380–1420 m, a.s.l.; ca. 55 km north west of the type locality; see Andreone et al. 2007) are conspecific. Additionally, tadpoles ZCMV 9739 collected at Imaloka (RNP: 21 ° 14 ' 32 "S, 47 ° 27 ' 55 "E, 1020 m, a.s.l.) and ZSM 1164 / 2007 from Sakaroa (RNP: 21 ° 15 '00.1"S, 47 ° 24 ' 53.6 "E) belong to Boophis boppa. The species has a known elevational distribution of ca. 1020–1400 m, a.s.l. Natural history (Fig. 12). Boophis boppa was locally abundant but thus far only found in undisturbed, primary forests along fast moving streams and was occasionally found along slow flowing tributaries adjacent to fast streams. Males of the species typically were calling at night from the surfaces of vegetation less than three meters in height (Fig. 12 A–B). Females of B. boppa were rarely encountered and were only observed while in amplexus (Fig. 12 C). We also confirm that Boophis boppa is syntopic with Boophis ankaratra at Maharira and that the two species can be found calling less than a meter apart. This is also consistent with Andreone et al. (2007), which found B. boppa (i.e. Boophis aff. ankaratra) and B. ankaratra to occur sympatrically. Other syntopic species of Boophis at Maharira include: B. madagascariensis, B. majori, B. aff. marojezensis, B. aff. picturatus, B. popi, and B. reticulatus. Conservation status. The new species is known from Ranomafana National Park and its vicinity, extending into the Antoetra area. While it is known from a geographic area less than ~ 5,000 km 2, there are no known immediate threats, reductions in quality or extent of habitat, or observed declines as the species is well protected within Ranomafana National Park. Therefore, the new species meets only criterion (B 1), and could become endangered in the future if the situation changes at Ranomafana, for instance through population declines from chytridiomycosis, which has been detected in the park (Bletz et al. 2015). We recommend a conservation status of Near Threatened, following IUCN (2001) criteria.Published as part of Hutter, Carl R., Lambert, Shea M., Cobb, Kerry A., Andriampenomanana, Zo Faniry & Vences, Miguel, 2015, A new species of bright-eyed treefrog (Mantellidae) from Madagascar, with comments on call evolution and patterns of syntopy in the Boophis ankaratra complex, pp. 531-555 in Zootaxa 4034 (3) on pages 537-546, DOI: 10.11646/zootaxa.4034.3.6, http://zenodo.org/record/23809
Natural variation in Drosophila melanogaster
No full textThis work is dedicated to studying natural variation in D. melanogaster at the DNA sequence and gene expression level. In addition I present a new version of the DNA polymorphism analysis program VariScan, which includes significant improvements.
In CHAPTER 1 I describe a genome scan of single nucleotide polymorphism in two natural D. melanogaster populations (from Africa and Europe) on the third chromosome. Together with polymorphism data previously published for the X chromosome of the same populations, this allows a comparative study of the polymorphism patterns of the X chromosome and an autosome. The frequency spectrum of mutations and the patterns of linkage disequilibrium are investigated. The observed patterns indicate that there is a significant difference in the behavior of the two chromosomes, as has already been suggested by previous studies. To uncover the reasons for this a coalescent based maximum likelihood method is applied that incorporates the effects of demographic history and unequal sex ratios. For the African population the differential behavior of the chromosomes can be explained by its demographic history and an excess of females. In Europe, a population bottleneck and an excess of males alone cannot explain the patterns we observe. The additional action of positive selection in this population is proposed as a possible explanation.
In CHAPTER 2 I investigate the variation in gene expression of the two aforementioned populations. Whole-genome microarrays are used to study levels of expression for 88% of all known genes in eight adult males from both populations. The observed levels of expression variation are equal in Africa and Europe, despite the fact that DNA sequence variation is much higher in Africa. This is evidence for the action of stabilizing selection governing levels of expression polymorphism. Supporting this view, genes involved in many different functions, and are therefore on strong selective constraint, show less variation than do genes with only few functions. The experimental design allows the search for genes which differ in their expression patterns between Europe and Africa and might therefore have undergone adaptive evolution. Detected candidates include genes putatively involved in insecticide resistance and food choice. Surprisingly, many genes over-expressed in Africa are involved in the formation and function of the flying apparatus.
In CHAPTER 3 I present version 2 of the program VariScan. This program was designed to analyse patterns of DNA sequence polymorphism on a chromosomal scale. The functionality of the core analysis tool, the wavelet decomposition, is described. In addition, multiple improvements to the previous version are presented. The program now supports the “pairwise deletion” option. This is essential for analysing data at the chromosome scale, since such data often contains incomplete information. It is now possible to add outgroup information, which allows the calculation of additional statistics. Furthermore, the separate analysis of different predefined chromosomal regions is added as an option. To increase the user friendliness, a graphical user interface is now included as part of the software package. Finally, VariScan is applied to published and computer-generated data and the ability of the wavelet-based analysis to uncover chromosomal regions with interesting DNA polymorphism patterns is demonstrated
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Optical fibre-tip probes for SERS: numerical study for design considerations
No full textEnhancement of sub-wavelength optical fields using sub-micron plasmonic probes has found many applications in chemical, material, biological and medical sciences. The enhancement is via localised surface-plasmon resonance (LSPR) which enables the highly sensitive vibrational-spectroscopy technique of surface-enhanced Raman scattering (SERS). Combining SERS with optical fibres can allow the monitoring of biochemical reactions in-situ with high resolution. Here, we study the electromagnetic-field enhancement of a tapered optical fibre-tip coated with gold nanoparticles (AuNPs) using finite-element simulations. We investigate the electric-field enhancement associated with metallic NPs and study the effect of parameters such as tip-aperture radius, cone angle, nanoparticle size and gaps between them. Our study provides an understanding for the design and application of metal-nanoparticle-coated optical-fibre-tip probes for SERS. The approach of using fibre-coupled delivery adds flexibility and simplifies the system requirements in SERS, making it suitable for cellular imaging and mapping bio-interfaces
