Data from: Genetic elimination of field-cage populations of Mediterranean fruit flies

Philip T. Leftwich, Martha Koukidou, Polychronis Rempoulakis, Hong-Fei Gong, Antigoni Zacharapolou, Tracey Chapman, Aris Economopolous, John Vontas, Luke Alphey, A. Economopoulos & A. Zacharopoulou
The Mediterranean fruit fly (medfly, Ceratitis capitata Wiedemann) is a pest of over 300 fruits, vegetables and nuts. The sterile insect technique (SIT) is a control measure used to reduce the reproductive potential of populations through the mass release of sterilized male insects that mate with wild females. However, SIT flies can display poor field performance, due to the effects of mass-rearing and of the irradiation process used for sterilization. The development of female-lethal RIDL...

High-resolution CONUS-wide downscaled rainfall estimates (HRCDRE)

Stergios Emmanouil, Andreas Langousis, Efthymios I. Nikolopoulos & Emmanouil N. Anagnostou
The spatiotemporal character of rainfall is particularly important for hydrologic modeling, as well as hydroclimatic risk estimation and impact assessment. Existing atmospheric reanalysis datasets offer extensive record lengths and global coverage, but usually their spatial resolution is coarse for distributed hydrologic simulations at small spatial scales. On the other hand, the temporal coverage of high-resolution radar-based rainfall estimates can be rather short for risk applications. To address these shortcomings, we simultaneously bias-correct and downscale a...

The demise of a wonder: evolutionary history and conservation assessments of the Wonder Gecko Teratoscincus keyserlingii (Gekkota, Sphaerodactylidae) in Arabia

Karin Tamar, Johannes Els, Panagiotis Kornilios, Pritpal Soorae, Pedro Tarroso, Evanthia Thanou, John Pereira, Junid Sha, Esmat Elfaki Mohammed Elhassan, Jeruel Cabadonga Aguhob, Saoud Faisal Badaam, Mohamed Mustafa Eltayeb, Ricardo Pusey, Theodore J. Papenfuss, Robert Macey & Salvador Carranza
Effective biodiversity conservation planning starts with the genetic characterization within and among focal populations, in order to understand the likely impact of threats for ensuring the long-term viability of the species. The Wonder Gecko, Teratoscincus keyserlingii, is one of nine members of the genus. The species is distributed in Iran, Afghanistan and Pakistan, with a small isolated population in the United Arab Emirates (UAE), where it is classified nationally as Critically Endangered. Within its Arabian...

Data from: Genetic structure in the European endemic seabird, Phalacrocorax aristotelis, was shaped by a complex interaction of historical and contemporary, physical and non-physical drivers

Evanthia Thanou, Stefano Sponza, Emily J. Nelson, Annika Perry, Sarah Wanless, Francis Daunt & Stephen Cavers
Geographically separated populations tend to be less connected by gene flow, as a result of physical or non-physical barriers preventing dispersal, and this can lead to genetic structure. In this context, highly mobile organisms such as seabirds are interesting because the small effect of physical barriers means non-physical ones may be relatively more important. Here we use microsatellite and mitochondrial data to explore the genetic structure and phylogeography of Atlantic and Mediterranean populations of a...

Trichonis Lake network

This network was installed after the Trichonis Lake, western Greece, 2007 earthquake sequence. Its scope was the monitoring of the aftershock sequence. Eight short period stations (0.5 to 50Hz), were installed one day after the main event (11th of April 2007) and the stations were uninstalled twenty days latter (2nd of May 2007). Data were recorded in miniseed format.

Effect of dapagliflozin on urine metabolome in patients with type 2 diabetes

Abstract Context Inhibitors of sodium-glucose cotransporters-2 have cardio- and renoprotective properties. However, the underlying mechanisms remain indeterminate. Objective To evaluate the effect of dapagliflozin on renal metabolism assessed by urine metabolome analysis in patients with type 2 diabetes. Design Prospective cohort study. Setting Outpatient diabetes clinic of a tertiary academic centre. Patients Eighty patients with HbA1c> 7% on metformin monotherapy were prospectively enrolled. Intervention Fifty patients were treated with dapagliflozin for 3 months. To exclude...

Data from: Micro-computed tomography: introducing new dimensions to taxonomy

Sarah Faulwetter, Aikaterini Vasileiadou, Michail Kouratoras, Thanos Dailianis & Christos Arvanitidis
Continuous improvements in the resolution of three-dimensional imaging have lead to an increased application of these techniques in conventional taxonomic research in recent years. Coupled with an ever increasing research effort in cybertaxonomy, three-dimensional imaging could give a boost to the development of virtual specimen collections, allowing rapid and simultaneous access to accurate virtual representations of type material. This paper explores the potential of micro-computed tomography, a non-destructive three-dimensional imaging technique based on X-ray energies,...

Data from: Predator-prey interactions between shell-boring beetle larvae and rock-dwelling land snails

Els Baalbergen, Renate Helwerda, Rense Schelfhorst, Ruth F. Castillo Cajas, Coline H. M. Van Moorsel, Robin Kundrata, Francisco W. Welter-Schultes, Sinos Giokas & Menno Schilthuizen
Drilus beetle larvae (Coleoptera: Elateridae) are specialized predators of land snails. Here, we describe various aspects of the predator-prey interactions between multiple Drilus species attacking multiple Albinaria (Gastropoda: Clausiliidae) species in Greece. We observe that Drilus species may be facultative or obligate Albinaria-specialists. We map geographically varying predation rates in Crete, where on average 24% of empty shells carry fatal Drilus bore holes. We also provide first-hand observations and video-footage of prey entry and exit...

Data from: Evolution and biogeography of the endemic Roucela complex (Campanulaceae: Campanula) in the eastern Mediterranean

Andrew A. Crowl, Clayton J. Visger, Guilhem Mansion, Ralf Hand, Hsin-Hui Wu, Georgia Kamari, Dimitrios Phitos & Nico Cellinese
At the intersection of geological activity, climatic fluctuations, and human pressure, the Mediterranean Basin – a hotspot of biodiversity – provides an ideal setting for studying endemism, evolution, and biogeography. Here, we focus on the Roucela complex (Campanula subgenus Roucela), a group of 13 bellflower species found primarily in the eastern Mediterranean Basin. Plastid and low-copy nuclear markers were employed to reconstruct evolutionary relationships and estimate divergence times within the Roucela complex using both concatenation...

Data from: Phylogeography of Aegean green toads (Bufo viridis subgroup): continental hybrid swarm vs. insular diversification with discovery of a new island endemic

Christophe Dufresnes, Petros Lymberakis, Panagiotis Kornilios, Romain Savary, Nicoals Perrin & Matthias Stöck
Background: Debated aspects in speciation research concern the amount of gene flow between incipient species under secondary contact and the modes by which post-zygotic isolation accumulates. Secondary contact zones of allopatric lineages, involving varying levels of divergence, provide natural settings for comparative studies, for which the Aegean (Eastern Mediterranean) geography offers unique scenarios. In Palearctic green toads (Bufo viridis subgroup or Bufotes), Plio-Pleistocene (~2.6 Mya) diverged species show a sharp transition without contemporary gene flow,...

The interplay of wind and uplift facilitates over-water flight in facultative soaring birds

Elham Nourani, Gil Bohrer, Paolo Becciu, Richard O Bierregaard, Olivier Duriez, Jordi Figuerola, Laura Gangoso, Sinos Giokas, Hiroyoshi Higuchi, Christina Kassara, Olga Kulikova, Nicolas Lecomte, Flavio Monti, Ivan Pokrovsky, Andrea Sforzi, Jean-François Therrien, Nikos Tsiopelas, Wouter MG Vansteelant, Duarte S Viana, Noriyuki M Yamaguchi, Martin Wikelski & Kamran Safi
Flying over the open sea is energetically costly for terrestrial birds. Despite this, over-water journeys of many birds, sometimes hundreds of kilometers long, are uncovered by bio-logging technology. To understand how these birds afford their flights over the open sea, we investigated the role of atmospheric conditions, specifically wind and uplift, in subsidizing over-water flight at the global scale. We first established that ∆T, the temperature difference between sea surface and air, is a meaningful...
