Madhuri S Patila, Narasimharao Kitchamsetti, Sameena R Mulani, Sachin R. Rondiya, Nishad G Deshpande, Ranjit A Patil, Russell W Cross, Nelson Y Dzade, Kirankumar K Sharma, Pramod S Patil, Yuan-Ron Ma, Hyung Koun Cho & Rupesh S Devan
We have synthesized closely packed hexagonal 2D plates and clustered nanoparticle morphologies of Ba(Sb/Ta)2O6 (BSTO) perovskite via the polymerizable complex method for photocatalyst dye degradation activities. The BSTO crystallized in a hexagonal structure. The presence of Ba2+, Sb5+, Ta5+, and O2− chemical states identified from XPS confirmed the formation of pure Ba(Sb/Ta)2O6 phase accompanied with a minor amount of TaOx. Furthermore, BSTO showed excellent photocatalytic activity for the degradation of various organic dyes. The kinetic...

Observation of Coherent Spin Waves in a Three-Dimensional Artificial Spin Ice Structure - data

Sourav Sahoo, Andrew May, Arjen Van Den Berg, Amrit Kumar Mondal, Sam Ladak & Anjan Barman
The spin wave (SW) dynamics of the 3D array were measured by using conventional Brillouin light scattering (BLS) technique. The 3D-ASI was fabricated by using a combination of TPL and thermal evaporation. BLS is a popular tool to measure SW dynamics of magnetic thin films and patterned nanostructures. It is a non-contact and thus non-invasive tool to measure thermally excited SWs at room temperature without any external excitation and under ambient conditions. This technique relies...

What you sample is what you get: ecomorphological variation in Trithemis (Odonata, Libellulidae) dragonfly wings reconsidered

Norman MacLeod, Banjamin Price & Zachary Stevens
Abstract Background The phylogenetic ecology of the Afro-Asian dragonfly genus Trithemis has been investigated previously by Damm et al. (in Mol Phylogenet Evol 54:870–882, 2010) and wing ecomorphology by Outomuro et al. (in J Evol Biol 26:1866–1874, 2013). However, the latter investigation employed a somewhat coarse sampling of forewing and hindwing outlines and reported results that were at odds in some ways with expectations given the mapping of landscape and water-body preference over the Trithemis...

Structure and in silico simulations of a cold-active esterase reveals its prime cold-adaptation mechanism - data

Nehad Noby, Husam Sabah Auhim, Samuel Winter, Harley L Worthy, Pierre J Rizkallah, Stephen A Wells & Darran Dafydd Jones
The structure was detmined of a cold active family IV esterase (EstN7) cloned from Bacillus cohnii strain N1. EstN7 is a dimer with a classical α/β hydrolase fold. It has an acidic surface that is thought to play a role in cold-adaption by retaining solvation under changed water solvent entropy at lower temperatures. The conformation of the functionally important cap region is significantly different to EstN7's closest relatives, forming a bridge-like structure with reduced helical...

Detecting the presence of nesting nightjar in upland clear-fell using drone-mounted thermal cameras

Mike Shewring & Jim Vafidis
1. Confirming the presence and location of European Nightjar Caprimulgus europaeus nests is a significant fieldwork challenge in ecological monitoring. Nest sites can be located through direct observation or capture and radio tracking of breeding individuals, however such work is time-consuming, disturbing and costly. 2. Unmanned Aerial Vehicles equipped with thermal sensors may enable rapid survey over large areas by detecting nest locations based on the contrast of relatively warm nests and the surrounding cooler...

Lift-off Dielectric Resonator Calibration, Measurement and Simulation Data

Samuel J Hefford, Nicholas Clark, Richard Gumbleton & Porch Adrian
Lift-Off Dielectric Resonators (LODRs) are a novel variation of the common open-ended dielectric resonator measurement setup where the dielectric position is manipulated. They comprise of a conducting cavity shield, and a dielectric puck. They are used to make measurements of microwave surface resistance of conducting end plates through measurement of the resonant frequency (f0) and unloaded Q-factor (Q0) by substituting these values into a characteristic equation. The characteristic equation is found by first determining geometric...

Data from: Quantifying nectar production by flowering plants in urban and rural landscapes

Nicholas Tew, Jane Memmott, Ian Vaughan, Stephanie Bird, Graham Stone, Simon Potts & Katherine Baldock
Floral resources (nectar and pollen) provide food for insect pollinators but have declined in the countryside due to land use change. Given widespread pollinator loss, it is important that we quantify their food supply to help develop conservation actions. While nectar resources have been measured in rural landscapes, equivalent data are lacking for urban areas, an important knowledge gap as towns and cities often host diverse pollinator populations. We quantified the nectar supply of urban...

Maryam Afzali
Diffusion-weighted images were acquired on a 3T Connectom MR imaging system with 300 mT/m gradients (Siemens Healthineers, Erlangen, Germany).

We asked the hunters about their hunting and dietary practices, changes in hunting practices, and perceived changes...

ADV channel hydrodynamics data set for six engineered logjam structures

Stephanie Muller, Elizabeth Follett, Pablo Ouro & Catherine A Wilson
Using small-scale laboratory experiments, the upstream and downstream hydrodynamics of six idealised engineered logjams were investigated using Acoustic Doppler Velocimetry. Velocity profiles were measured along the channel centreline upstream and downstream of these jams. Velocity records were decomposed into time-averaged and fluctuation components, allowing the analysis of first and second order turbulence statistics at each measurement location and for each logjam. The data set comprises six excel files, with a separate file for each jam:...

Populations of high-value predators reflect the traits of their prey dataset

Cayetano Gutierrez Canovas, Thomas Worthington, David Noble, Daniel Perkins, Ian Vaughan, Guy Woodward, Steve Ormerod & Isabelle Durance
The extent to which prey traits combine to influence the abundance of predators is still poorly understood, particularly for mixed predators in sympatry and in aquatic ecosystems. In this study, we characterise prey use and distribution in iconic bird (grey wagtails and Eurasian dippers) and fish species (brown trout and Atlantic salmon) to assess whether prey traits could predict populations of these four riverine predators. Specifically, we hypothesised that: (i) Prey key traits would predict...
