Data from: Atypical panmixia in a European dolphin species (Delphinus delphis); implications for the evolution of diversity across oceanic boundaries.

Andre E. Moura, Ada Natoli, Emer Rogan & Alan R. Hoelzel
Despite the scarcity of geographical barriers in the ocean environment, delphinid cetaceans often exhibit marked patterns of population structure on a regional scale. The European coastline is a prime example, with species exhibiting population structure across well defined environmental boundaries. Here we undertake a comprehensive population genetic study on the European common dolphin (Delphinus delphis, based on 492 samples and 15 loci) and establish that this species shows exceptional panmixia across most of the study...

GaN and InGaN nanowires prepared by metal-assisted electroless etching: experimental and theoretical studies

Adel Najar, Assa S. Aravindh, Bin Xin, Somak Mitra & Iman S. Roqan
We investigate the optical and structural properties of GaN and InGaN nanowires (NWs) fabricated by metal-assisted electroless etching in a hydrofluoric acid (HF) solution. The emission spectra of GaN and InGaN NWs exhibit a red shift compared to the as-grown samples resulting from an increase in the surface-to-volume ratio and stress relaxation in these nanostructures. The carrier lifetimes of GaN and InGaN NWs were measured. In addition, density functional theory (DFT) investigations were carried out...

Phosphorene is a new 2D material that has recently attracted much attention owing to its fascinating electrical, optical, thermal, and chemical properties. Here, we report on high-quality exfoliation of black phosphorus nanosheets, with controllable size produced in large quantities by liquid phase exfoliation using N-methyl-2-pyrrolidone (NMP) as a solvent under ambient conditions. The as-synthesized few layers show a great potential for solar energy conversion based on the optical results shown in this work.

This study aimed to explore the practice patterns of non-dialysis-dependent CKD care in an affluent developing country. Settings Primary and specialised healthcare facilities of public and private sectors in the United Arab Emirates. Participants 159 non-nephrologist physicians practising in the United Arab Emirates. Interventions A 28-item online self-administered questionnaire based on CKD clinical practice guidelines. Primary and secondary outcome measures The...

Root associated fungi in Arctic Glacier Forlands raw sequences

Pernille Bronken Eidesen, Synnøve S. Botnen, Sunil Mundra & Håvard Kauserud
Climate change causes Arctic glaciers to retreat faster, exposing new areas for colonization. Several pioneer plants likely to colonize recent deglaciated, nutrient-poor areas depend on fungal partners for successful establishment. Little is known about general patterns or characteristics of facilitating fungal pioneers and how they vary with regional climate in the Arctic. The High Arctic Archipelago Svalbard represents an excellent study system to address these questions, as glaciers cover ∼60% of the land surface and...

Data from: Patterns of population structure for inshore bottlenose dolphins along the eastern United States

Vince P. Richards, Thomas W. Greig, Patricia A. Fair, Stephen D. McCulloch, Christine Politz, Ada Natoli, Carlos A. Driscoll, A. Russell Hoelzel, Victor David, Gregory D. Bossart & Jose V. Lopez
Globally distributed, the bottlenose dolphin (Tursiops truncatus) is found in a range of offshore and coastal habitats. Using 15 microsatellite loci and mtDNA control region sequences, we investigated patterns of genetic differentiation among putative populations along the eastern US shoreline (the Indian River Lagoon, Florida, and Charleston Harbor, South Carolina) (microsatellite analyses: n = 125, mtDNA analyses: n = 132). We further utilized the mtDNA to compare these populations with those from the Northwest Atlantic,...

Patterns of volatile diversity yield insights into the genetics and biochemistry of the date palm fruit volatilome

Jonathan Flowers, Khaled Hazzouri, Alain Lemansour, Tiago Capote, Muriel Gros-Balthazard, Sylvie Ferrand, Marc Lebrun, Khaled Amiri & Michael Purugganan
Volatile organic compounds are key components of the fruit metabolome that contribute to traits such as aroma and taste. Here we report on the diversity of 90 flavor-related fruit traits in date palms (Phoenix dactylifera L.) including 80 volatile organic compounds, which collectively represent the fruit volatilome, as well as 6 organic acids, and 4 sugars in tree-ripened fruits. We characterize these traits in 148 date palms representing 135 varieties using headspace solid-phase microextraction gas...

Data from: Is MHC diversity a better marker for conservation than neutral genetic diversity? a case study of two contrasting dolphin populations

Oliver Manlik, Michael Krutzen, Anna M. Kopps, Janet Mann, Lars Bejder, Simon J. Allen, Celine Frere, Richard C. Connor & William B. Sherwin
Genetic diversity is essential for populations to adapt to changing environments. Measures of genetic diversity are often based on selectively neutral markers, such as microsatellites. Genetic diversity to guide conservation management, however, is better reflected by adaptive markers, including genes of the major histocompatibility complex (MHC). Our aim was to assess MHC and neutral genetic diversity in two contrasting bottlenose dolphin (Tursiops aduncus) populations in Western Australia—one apparently viable population with high reproductive output (Shark...

Microbial communities associated with the camel tick, Hyalomma dromedarii: 16S rRNA gene-based analysis

Mohammad Ali Al-Deeb, Nighat Perveen, Sabir Bin Muzaffar & Ranjit Vijayan
Background Hyalomma dromedarii is a very important blood-feeding ectoparasite that affects the health of camels in many parts of the world including the United Arab Emirates (UAE). The current study was conducted to assess the profile of the bacterial communities associated with H. dromedarii in the eastern part of the UAE in 2019 in comparison with ticks collected in 2010. Methods We performed 16S rRNA gene amplicon sequencing using primers flanking the V3 V4 region....

Supramolecular encapsulation of benzimidazole-derived drugs by cucurbit[7]uril

Apurba L. Koner, Indrajit Ghosh, Na'il Saleh & Werner M. Nau
UV–vis and NMR spectroscopic techniques were employed to demonstrate the ability of the synthetic macrocyclic host cucurbit[7]uril (CB7) to solubilize and stabilize widely used fungicides and anthelmintic drugs of the benzimidazole family in water, namely, albendazole (ABZ), carbendazim (CBZ), thiabendazole (TBZ), fuberidazole (FBZ), and the parent benzimidazole (BZ). CB7 binds the protonated forms of these guests very strongly (e.g., K = 2.6 × 107 L/mol for ABZ) but their neutral forms significantly more weakly (e.g., K...
