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 Conservation International.

The dataset contains measurements of the annual average abundance, biomass and elemental composition (C, N, P) of consumers (fish and invertebrates) in six rivers within sub-catchments of the Hampshire Avon of contrasting geology (clay, sand, chalk).

Chlorophyll-a content and ash-free dry mass of quantitative samples of the biofilm on benthic substrate from three chalkstream sites in the Wessex chalk area (Nine Mile River, River Till and River Wylye). Chlorophyll a content and biomass were determined from up to 10 replicate samples at each site on each sampling occasion. The data are presented as means with standard deviation. Data were collected on seven occasions on the Wylye and Nine Mile River and on five occasions on the Till, between October 2012 and October 2013. Data were collected to construct quantified food webs detailing the flux of mass and nutrients between nodes of the food web. This dataset was created as part of work package 3.2 of the Wessex Biodiversity & Ecosystem Service Sustainability (BESS) project.

The dataset contains denitrification, anaerobic ammonium oxidation (anammox) and nitrification activity of riverine sediments in the Hampshire Avon catchment (UK). Six rivers within sub-catchments of contrasting geology (clay, sand, chalk) were investigated. Data were obtained via direct, field-based measurements in seasonal campaigns conducted between spring 2013 and winter 2014. Also included are chemical parameters determined in porewaters prior to in situ rate measurements.

This dataset contains anaerobic ammonium oxidation (anammox) and denitrification activity of riverine sediments in the Hampshire Avon catchment (UK). Nine rivers within sub-catchments of contrasting geology (clay, sand, chalk) were investigated. Data were obtained via laboratory incubations (potential data) and direct, field-based measurements (in situ data) in summer 2013. Also included are chemical parameters determined in porewaters prior to in situ rate measurements.

Ash-free dry mass (AFDM) of three distinct size fractions of organic matter (>1cm, >1mm and > 0.025mm) collected in quantitative samples of the benthic substrate determined from up to 10 replicate samples at three chalkstream sites in the Wessex chalk area (Nine Mile River, River Till and River Wylye) on each sampling occasion. Data were collected on seven occasions on the Wylye and Nine Mile River and on five occasions on the Till, between October 2012 and October 2013. Data were collected to construct quantified food webs detailing the flux of mass and nutrients between nodes of the food web. This dataset was created as part of work package 3.2 of the Wessex Biodiversity & Ecosystem Service Sustainability (BESS) project.

The dataset contains measurements of temperature (°C) and light availability (Lux) in rivers in the Hampshire Avon catchment (UK). Six rivers within sub-catchments of contrasting geology (clay, sand, chalk) were investigated. The stream sites monitored were chosen to reflect a gradient of base flow index. Data were obtained via direct, field-based measurements every 15 minutes from February 2013 to (max) December 2014 with sensors tethered to the bed of the river at each site.

Density and biomass of fish taxa from three chalkstreams in the Wessex chalk area: Nine Mile River, River Till and River Wylye. Data were collected on five occasions, between October 2012 and October 2013. The density of fish taxa at each of the three streams was estimated using benthic fish sampling and multi-pass electrofishing. The mean biomass of individuals of each taxon at each site on each occasion was then applied to the density estimates to derive an estimate of the biomass per m2 of each taxon at each site on each occasion. Data were collected to quantify food webs detailing the flux of mass and nutrients between nodes of the food web. This dataset was created as part of work package 3.2 of the Wessex Biodiversity & Ecosystem Service Sustainability (BESS) project.

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 and episodic ebullition. The dataset also includes measurements of water level and meteorological variables (net radiation, soil temperature, air pressure) along with an allometric measure of plant biomass (Vascular Green Area).

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.
