The influence of large woody debris (LWD) on in situ riverbed nitrogen transformations in the Hammer Stream (Hampshire, UK)M. Trimmer
This dataset contains results from in situ field measurements of riverbed nitrogen transformations in the Hammer Stream, a sandy tributary of the River Rother in West Sussex, UK. Measurements were performed in November 2014 and February, April and July 2015. The data include baseline concentrations of nutrients (NO2, NO3, NH3, PO4), chloride, oxygen, pH, temperature, Fe(II), organic carbon, 15N-N2 and methane (CH4) and nitrous oxide (N2O) sampled from porewater prior to injection of 15N-nitrate.
This dataset includes measurements of methane fluxes from two lowland floodplain fen sites in East Anglia, UK under conservation management (Sutton and Strumpshaw Fens). The data were collected on seven monthly to bimonthly visits during 2013 and comprise methane ebullition fluxes measured using inverted funnels, and methane fluxes measured using static chambers. The tall, static chambers captured methane transported by diffusion, plant-mediated transport and steady ebullition, whereas the inverted funnels captured methane transported by steady...
This dataset includes capture data for insectivorous bats captured with harp traps in Sabah, Malaysia, and dietary metabarcoding data. The dietary data was generated through obtaining bat faeces, extracting the DNA, amplifying it using ZBJ-ArtF1c ZBJ-ArtR2c primers, and then sequencing it on an illumina miseq. Code to aid interpreting the data can be found at https://doi.org/10.17636/01044623 This data was collected as part of the NERC-funded LOMBOK HMTF project, also using a small grant from Bat...
This data set includes soil chemical, physical and microbial properties collected across a two-century glacial chronosequence across six streams in Glacier Bay, Southeast Alaska, U.S.A. We measured soil potential nitrification, denitrification, as well as stable isotopes (delta-15N and delta-13C) of leaves and soil to establish how physical and biological changes associated with ecosystem development interact to determine rates of carbon (C) and nitrogen (N) turnover. Secondly, how these interactions were reflected in the isotopic signature...

River water samples were collected at 48-hr intervals from Summer 2013 to Summer 2014 and samples were analysed for selected solutes and...
The dataset comprises biochemical measurements of salt marsh soil, and samples from fields on former salt marsh, taken using a soil corer. Sampling was conducted at three restored salt marshes and six accidentally breached sites on the Essex coast, UK, providing a chronosequence from 16 to 114 years since restoration of tidal flow. Natural salt marsh at all sites were also sampled, along with adjacent fields on former salt marsh (where access permitted). All salt...
Adaptation to ecologically contrasting niches can lead to the formation of new species. Theoretically, this process of ecological speciation can be driven by pleiotropic “magic traits” that genetically link natural and sexual selection. To qualify as a true magic trait, the pleiotropic function of a gene must be reflected in biologically relevant mechanisms underlying both local adaptation and mate choice. The immune genes of the major histocompatibility complex (MHC) contribute to parasite resistance and also...
Data from: Unidirectional diploid–tetraploid introgression among British birch trees with shifting ranges shown by restriction site-associated markersJasmin Zohren, Nian Wang, Igor Kardailsky, James S. Borrell, Anika Joecker, Richard A. Nichols & Richard J. A. Buggs
Hybridization may lead to introgression of genes among species. Introgression may be bidirectional or unidirectional, depending on factors such as the demography of the hybridizing species, or the nature of reproductive barriers between them. Previous microsatellite studies suggested bidirectional introgression between diploid Betula nana (dwarf birch) and tetraploid B. pubescens (downy birch) and also between B. pubescens and diploid B. pendula (silver birch) in Britain. Here, we analyse introgression among these species using 51 237...
Data from: Evidence for a pervasive ‘idling-mode’ activity template in flying and pedestrian insectsAndrew M. Reynolds, Hayley B. C. Jones, Jane K. Hill, Aislinn J. Pearson, Kenneth Wilson, Stephan Wolf, Ka S. Lim, Donald R. Reynolds, Jason W. Chapman, J. K. Hill, S. Wolf, K. Wilson, J. W. Chapman, H. B. C. Jones, K. S. Lim, A. J. Pearson, A. M. Reynolds & D. R. Reynolds
Understanding the complex movement patterns of animals in natural environments is a key objective of ‘movement ecology’. Complexity results from behavioural responses to external stimuli but can also arise spontaneously in their absence. Drawing on theoretical arguments about decision-making circuitry, we predict that the spontaneous patterns will be scale-free and universal, being independent of taxon and mode of locomotion. To test this hypothesis, we examined the activity patterns of the European honeybee, and multiple species...
Phylogeographic reconstructions of co-distributed taxa can help reveal the interplay between abiotic factors, such as altitude and climate, and species-specific attributes, in shaping patterns of population genetic structure. Recent studies also demonstrate the value of both range-wide sampling and species distribution modeling (SDM) in comparative phylogeography. Here we combine these approaches to study the population histories of four phylogenetically-related forest-dependent bat species. All are endemic to the mountainous island of Taiwan but show differences in...
Data from: Diet of the insectivorous bat Pipistrellus nathusii during autumn migration and summer residenceFrauke Krüger, Elizabeth L. Clare, William O. C. Symondson, Oskars Keišs & Gunārs Pētersons
Migration is widespread among vertebrates. Yet bat migration has received little attention and only in the recent decades knowledge of it has been gained. Migration can cause significant changes in behaviour and physiology, due to increasing energy demands and aerodynamic constraints. Dietary shifts, for examples, have been shown to occur in birds before onset of migration. For bats it is not known if a change in diet occurs during migration, although especially breeding season related...
Data from: An integrative approach to detect subtle trophic niche differentiation in the sympatric trawling bat species Myotis dasycneme and Myotis daubentoniiFrauke Krüger, Elizabeth L. Clare, Stefan Greif, Bjoern M. Siemers, William O. C. Symondson & Robert S. Sommer
Bats are well known for species richness and ecological diversity thus they provide a good opportunity to study relationships and interaction between species. To assess interactions we consider distinct traits which are likely to be triggered by niche shape and evolutionary processes. We present data on the trophic niche differentiation between two sympatric European trawling bat species, Myotis dasycneme and M. daubentonii, incorporating a wide spectrum of methodological approaches. We measure morphological traits involved in...
