Invasive Fruit Flies (Diptera: Drosophilidae) Meet in a Biodiversity Hotspot
J. Entomol. Res. Soc., 19(1): 61-69, 2017 ISSN:1302-0250 Invasive Fruit Flies (Diptera: Drosophilidae) Meet in a Biodiversity Hotspot Carla REGO1* António Franquinho AGUIAR2 Délia CRAVO2 Mário BOIEIRO1 1Centre for Ecology, Evolution and Environmental Changes (cE3c), Azorean Biodiversity Group and Department of Agrarian Sciences, University of Azores, Angra do Heroísmo, Azores, PORTUGAL 2Laboratório de Qualidade Agrícola, Camacha, Madeira, PORTUGAL e-mails: *[email protected], [email protected], [email protected], [email protected] ABSTRACT Oceanic islands’ natural ecosystems worldwide are severely threatened by invasive species. Here we discuss the recent finding of three exotic drosophilids in Madeira archipelago -Acletoxenus formosus (Loew, 1864), Drosophila suzukii (Matsumura, 1931) and Zaprionus indianus (Gupta, 1970). Drosophila suzukii and Z. indianus are invasive species responsible for severe economic losses in fruit production worldwide and became the dominant drosophilids in several invaded areas menacing native species. We found that these exotic species are relatively widespread in Madeira but, at present, seem to be restricted to human disturbed environments. Finally, we stress the need to define a monitoring program in the short-term to determine population spread and environmental damages inflicted by the two invasive drosophilids, in order to implement a sustainable and effective control management strategy. Key words: Biological invasions, Drosophila suzukii, invasive species, island biodiversity, Madeira archipelago, Zaprionus indianus. INTRODUCTION Oceanic islands are known to contribute disproportionately to their area for Global biodiversity and by harbouring unique evolutionary lineages and emblematic plants and animals (Grant,1998; Whittaker and Fernández-Palácios, 2007). Nevertheless, many of these organisms are particularly vulnerable to human-mediated changes in their habitats due to their narrow range size, low abundance and habitat specificity (Paulay, 1994). -

Keesey1*, Jin Zhang1, Ana Depetris-Chauvin1, George F. Obiero2, Markus Knaden1‡*, and Bill S. Hansson1‡* Comparative analysis of multiple genomes has been used extensively to examine the evolution of chemosensory receptors across the genus Drosophila. However, few studies have delved into functional characteristics, as most have relied exclusively on genomic data alone, especially for non-model species. In order to increase our understanding of olfactory evolution, we have generated a comprehensive assessment of the olfactory functions associated with the antenna and palps for Drosophila suzukii as well as sev- eral other members of the subgenus Sophophora, thus creating a functional olfactory landscape across a total of 20 species. Here we identify and describe several common elements of evolution, including consistent changes in ligand spectra as well as relative receptor abundance, which appear heavily correlated with the known phylogeny. We also combine our functional ligand data with protein orthologue alignments to provide a high-throughput evolutionary assessment and predictive model, where we begin to examine the underlying mechanisms of evolutionary changes utilizing both genetics and odorant binding affinities. In addition, we document that only a few receptors frequently vary between species, and we evaluate the justifications for evolution to reoccur repeatedly within only this small subset of available olfactory sensory neurons. -

The Mariner Transposable Element in the Drosophilidae Family
Heredity 73 (1994) 377—385 Received 10 February 1994 The Genetical Society of Great Britain The mariner transposable element in the Drosophilidae family FREDERIC BRUNET, FABIENNE GODIN, JEAN A. DAVID & PIERRE CAPY* Laboratoire Populations, Genétique et Evolution, CNRS, 91198 Gif/Yvette Cedex, France Thedistribution of the mariner transposable element among Drosophilidae species was investi- gated using three differetìt techniques, i.e. squash blots, Southern blots and PCR amplification, using two sets of primers (one corresponding to the Inverted Terminal Repeats and the other to two conserved regions of the putative transposase). Our results and those of others show that the distribution of mariner is not uniform and does not follow the phylogeny of the host species. An analysis of geographical distribution, based on endemic species, shows that mariner is mainly present in Asia and Africa. At least two hypotheses may be proposed to explain the specific and geographical distributions of this element. Firstly, 'they may be the results of several horizontal transmissions between Drosophila species and/or between Drosophila species and one or several donor species outside the Drosophilidae family. Secondly, these particular distributions may correspond to the evolution of the mariner element from an ancestral copy which was present in the ancestor of the Drosophilidae family.

In all cases, the evolutionary history of these Introduction elements is not simple and more information is neces- Thedistribution of the mariner transposable elements sary about the variability within and between more or in Drosophila was previously investigated by less closely related species.

Tambones1, Annabelle Haudry2, Maryanna C. Simão1 and Claudia M. A. Carareto1* Abstract Background: The use of large-scale genomic analyses has resulted in an improvement of transposable element sampling and a significant increase in the number of reported HTT (horizontal transfer of transposable elements) events by expanding the sampling of transposable element sequences in general and of specific families of these elements in particular, which were previously poorly sampled. In this study, we investigated the occurrence of HTT events in a group of elements that, until recently, were uncommon among the HTT records in Drosophila – the Jockey elements, members of the LINE (long interspersed nuclear element) order of non-LTR (long terminal repeat) retrotransposons. The sequences of 111 Jockey families deposited in Repbase that met the criteria of the analysis were used to identify Jockey sequences in 48 genomes of Drosophilidae (genus Drosophila, subgenus Sophophora: melanogaster, obscura and willistoni groups; subgenus Drosophila: immigrans, melanica, repleta, robusta, virilis and grimshawi groups; subgenus Dorsilopha: busckii group; genus/subgenus Zaprionus and genus Scaptodrosophila). Results: Phylogenetic analyses revealed 72 Jockey families in 41 genomes. Combined analyses revealed 15 potential HTT events between species belonging to different -

This gene, which that some species harbored two types of genes: those with an exists as a single copy, was named Amyrel. It is strikingly intron at position 177, which is supposed to be ancestral (14), and divergent from Amy because the amino acid divergence is 40%. those without an intron at this position. This was the case in The coding sequence is interrupted by a short intron at Drosophila takahashii, Drosophila lucipennis, and in the Drosoph- position 655, which is unusual in amylase genes. Amyrel has ila obscura group. Phylogenetic trees clearly showed that “intron- also been cloned in Drosophila ananassae, Drosophila pseudoob- less” genes of these species were excluded from the Amy tree but scura, and Drosophila subobscura and is likely to be present remained clustered together, suggesting that they were paralogs throughout the Sophophora subgenus, but, to our knowledge, (14).

The Origin of Chromosomal Inversions As a Source of Segmental
www.nature.com/scientificreports OPEN The origin of chromosomal inversions as a source of segmental duplications in the Sophophora Received: 07 June 2016 Accepted: 05 July 2016 subgenus of Drosophila Published: 29 July 2016 Eva Puerma, Dorcas J. Orengo & Montserrat Aguadé Chromosomal inversions can contribute to the adaptation of organisms to their environment by capturing particular advantageous allelic combinations of a set of genes included in the inverted fragment and also by advantageous functional changes due to the inversion process itself that might affect not only the expression of flanking genes but also their dose and structure. Of the two mechanisms originating inversions —ectopic recombination, and staggered double-strand breaks and subsequent repair— only the latter confers the inversion the potential to have dosage effects and/or to generate advantageous chimeric genes. In Drosophila subobscura, there is ample evidence for the adaptive character of its chromosomal polymorphism, with an important contribution of some warm- climate arrangements such as E1+2+9+12. Here, we have characterized the breakpoints of inversion E12 and established that it originated through the staggered-break mechanism like four of the five inversions of D. subobscura previously studied. This mechanism that also predominates in the D. melanogaster lineage might be prevalent in the Sophophora subgenus and contribute to the adaptive character of the polymorphic and fixed inversions of its species. Finally, we have shown that the D. subobscura inversion breakpoint regions have generally been disrupted by additional structural changes occurred at different time scales. Structural variation ranging from chromosomal inversions to chromosome fusions does not only lead to genome reorganization through time but it can also contribute to the adaptation of organisms to their environment. -
