The perilous state of seagrass in the British Isles
(2016)Seagrass ecosystems face widespread threat from reduced water quality, coastal development and poor land use. In recent decades, their distribution has declined rapidly, and in the British Isles, this loss is thought to ... -
Computational exploration of the reactionmechanism of the Cu + -catalysed synthesis of indoles from N-aryl enaminones
(2016)We have studied the role of Cu+ -phenantroline as a catalyst in the cyclization ofN-aryl-enaminones using density-functional theory computations. The catalyst was found to bind the substrate upon deprotonation of its ... -
Experiments on torrefied wood pellet
(2016)Samples of torrefied wood pellet produced by low-temperature microwave pyrolysis were tested through a series of experiments relevant to present and near future waste to energy conversion technologies. Operational performance ... -
Post main sequence planetary system evolution
(2016)The fates of planetary systems provide unassailable insights into their formation and represent rich cross-disciplinary dynamical laboratories. Mounting observations of post-main-sequence planetary systems necessitate a ... -
Data based reconstruction of complex geospatial networks, nodal positioning and detection of hidden nodes
(2016)Given a complex geospatial network with nodes distributed in a two-dimensional region of physical space, can the locations of the nodes be determined and their connection patterns be uncovered based solely on data? We ... -
Extragalactic background light measurements and applications
(2016)This review covers the measurements related to the extragalactic background light intensity from γ-rays to radio in the electromagnetic spectrum over 20 decades in wavelength. The cosmic microwave background (CMB) remains ... -
Using simulation to evaluate wildlife survey designs
(2016)Logistically demanding and expensive wildlife surveys should ideally yield defensible estimates. Here, we show how simulation can be used to evaluate alternative survey designs for estimating wildlife abundance. Specifically, ... -
Proprioceptive feedback determines visuomotor gain in Drosophila
(2016)Multisensory integration is a prerequisite for effective locomotor control in most animals. Especially, the impressive aerial performance of insects relies on rapid and precise integration of multiple sensory modalities ... -
A novel method of microsatellite genotyping-by-sequencing using individual combinatorial barcoding
(2016)This study examines the potential of next-generation sequencing based ‘genotyping-by-sequencing’ (GBS) of microsatellite loci for rapid and cost-effective genotyping in large-scale population genetic studies. The recovery ... -
Predator olfactory cues generate a foraging–predation trade-off through prey apprehension
(2016)Most animals are faced with the challenge of securing food under the risk of predation. This frequently generates a trade-off whereby animals respond to predator cues with reduced movement to avoid predation at the direct ... -
Random noise can help to improve synchronization of excimer laser pulses
(2016)Recently, we have reported on a compact microcontroller-based unit developed to accurately synchronize excimer laser pulses (Mingesz et al. 2012 Fluct. Noise Lett. 11, 1240007 (doi:10.1142/S021947751240007X)). We have shown ... -
Peculiar macrophagous adaptations in a new Cretaceous pliosaurid
(2015)During the Middle and Late Jurassic, pliosaurid plesiosaurs evolved gigantic body size and a series of craniodental adaptations that have been linked to the occupation of an apex predator niche. Cretaceous pliosaurids (i.e. ... -
Ants determine their next move at rest
(2016)To find useful work to do for their colony, individual eusocial animals have to move, somehow staying attentive to relevant social information. Recent research on individualTemnothorax albipennis ants moving inside their ... -
Trophic niche divergence among colour morphs that exhibit alternative mating tactics
(2016)Discrete colour morphs associated with alternative mating tactics are assumed to be ecologically equivalent. Yet suites of behaviours linked with reproduction can also favour habitat segregation and exploitation of different ... -
Markovian language model of the DNA and its information content
(2016)This work proposes a Markovian memoryless model for the DNA that simplifies enormously the complexity of it. We encode nucleotide sequences into symbolic sequences, called words, from which we establish meaningful length ... -
Sharpening coarse-to-fine stereo vision by perceptual learning
(2016)Neurons in the early visual cortex are finely tuned to different low-level visual features, forming a multi-channel system analysing the visual image formed on the retina in a parallel manner. However, little is known about ... -
Isotopic evidence for residential mobility of farming communities during the transition to agriculture in Britain
(2016)Development of agriculture is often assumed to be accompanied by a decline in residential mobility, and sedentism is frequently proposed to provide the basis for economic intensification, population growth and increasing ... -
The cervical anatomy of Samotherium,an intermediate-necked giraffid
(2015)Giraffidae are represented by many extinct species. The only two extant taxa possess diametrically contrasting cervical morphology, as the okapi is short-necked and the giraffe is exceptionally long-necked.Samotherium ... -
Phenotype limited distributions
(2015)In our seasonal world, animals face a variety of environmental conditions in the course of the year. To cope with such seasonality, animals may be phenotypically flexible, but some phenotypic traits are fixed. If fixed ... -
Fractal measures of spatial pattern as a heuristic for return rate in vegetative systems
(2016)Measurement of population persistence is a long-standing problem in ecology in particular, whether it is possible to gain insights into persistence without long time-series. Fractal measurements of spatial patterns, such ...
