The vulnerability of shellfish aquaculture to climate change and ocean acidification– a global assessment

Phoebe Stewart-Sinclair, Tom Wilding, Kim Last & Ben Payne
Human-induced climate change and ocean acidification (CC-OA) is changing the physical and biological processes occurring within the marine environment, with poorly understood implications for marine life. Within the aquaculture sector, molluscan culture is a relatively benign method of producing a high-quality, healthy and sustainable protein source for the expanding human population. We modelled the Vulnerability of global bivalve mariculture to impacts of CC-OA over the period 2020 to 2100, under RCP8.5. Vulnerability, assessed at the...

RSMP Baseline Dataset

Keith Cooper
This dataset was compiled for the Regional Seabed Monitoring Plan (RSMP) baseline assessment reported in Cooper and Barry (2017). The dataset comprises of 33,198 macrofaunal samples (83% with associated data on sediment particle size composition) covering large parts of the UK continental shelf. Whilst most samples come from existing datasets, also included are 2,500 new samples collected specifically for the purpose of this study. These new samples were collected during 2014-2016 from the main English...

Aim: Europe’s only globally critically endangered seabird, the Balearic shearwater (Puffinus mauretanicus), is thought to have expanded its post-breeding range northwards into UK waters, though its distribution there is not yet well understood. This study aims to identify environmental factors associated with the species’ presence, and map the probability of presence of the species across the western English Channel and southern Celtic Sea, and estimate the number of individuals in this area. Location: The western...

Data from: Metabarcoding and mitochondrial metagenomics of endogean arthropods to unveil the mesofauna of the soil

Paula Arribas, Carmelo Andújar, Kevin Hopkins, Matthew Shepherd & Alfried P. Vogler
Biological communities inhabiting the soil are among the most diversified, complex and yet most poorly studied terrestrial ecosystems. The greatest knowledge gaps apply to the arthropod mesofauna (0·1–2 mm body size) because conventional morphological and molecular approaches are in many cases insufficient for the characterisation of these complex communities. The development of high-throughput sequencing (HTS) methodologies is required to solve current impediments and to further advance our understanding of below-ground biodiversity. We propose a flotation–Berlese–flotation...

Data from: Fractal measures of spatial pattern as a heuristic for return rate in vegetative systems

Michael A. Irvine, Emma L. Jackson, Emma J. Kenyon, Kevan J. Cook, Matthew J. Keeling & James C. Bull
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 as the Korcak exponent or boundary dimension, have been proposed as indicators of the persistence of underlying dynamics. Here we explore under what conditions a predictive relationship between fractal measures and persistence exists. We combine theoretical arguments with an aerial snapshot and time series from...

Experimental evidence that novel land management interventions inspired by history enhance biodiversity

Robert Hawkes, Jennifer Smart, Andy Brown, Helen Jones, Steve Lane, Colin Lucas, James McGill, Nick Owens, Amanda Ratier Backes, Jonathan Webb, Doreen Wells & Paul Dolman
To address biodiversity declines within semi-natural habitats, land-management must cater for diverse taxonomic groups. Integrating our understanding of the ecological requirements of priority (rare, scarce or threatened) species through ‘biodiversity auditing’, with that of the intensity and complexity of historical land-use, encourages novel forms of management. Experimental confirmation is needed to establish whether this enhances biodiversity conservation relative to routine management. Biodiversity auditing and historical land-use of dry-open terrestrial habitats in Breckland (Eastern England) both...

Data from: The fifth review of Birds of Conservation Concern in the United Kingdom, Channel Islands and Isle of Man and second IUCN Red List assessment of extinction risk of birds for Great Britain

Andrew Stanbury, Mark Eaton, Nicholas Aebischer, Dawn Balmer, Andy Brown, Andy Douse, Patrick Lindley, Neil McCulloch, David Noble & Win Ilka
The fifth review of Birds of Conservation Concern (BoCC5) in the UK, Channel Islands and Isle of Man assessed and assigned 245 species to updated Red, Amber and Green lists of conservation concern and showed a continuing decline in the status of our bird populations. In total, 70 species (29% of those assessed) are now on the Red list, up from 36 species in the first review in 1996. Since the last review, in 2015,...

The Pantheon database: habitat related traits, conservation status and taxa associations for invertebrates in England

J. Webb, D. Heaver, D. Lott, H.J. Dean, J. Van Breda, J. Curson, M.C. Harvey, M. Gurney, D.B. Roy, A. Van Breda, M. Drake, K.N.A. Alexander & G. Foster
The Pantheon database contains habitat-related traits, feeding guilds, conservation status (including rarity and threat status), legal protection data and associations with other taxa for just over 11,700 invertebrates. The database has been developed for invertebrates within England so the data should be used with caution when applying it to invertebrates of other countries. The data have been extracted from numerous sources within the published literature and compiled and categorised by entomological experts over a number...

T.J.P. Travers, J. Alison, S.D. Taylor, H.Q.P. Crick & J.A. Hodgson
The results of an analysis of the connectivity of sixteen priority habitat networks in England using the Condatis methodology. The dataset includes conductance scores for each of the priority habitat networks (an overall assessment of how connected the habitat network is), the flow scores for each contiguous habitat patch within each of the habitat networks (the importance of that patch to connectivity), as well as details of protection. Additionally, the dataset includes data and scripts...

Mapping differences in mammalian distributions and diversity using environmental DNA from rivers

Allan McDevitt, Holly Broadhurst, Luke Gregory, Emma Bleakley, Joseph Perkins, Jenna Lavin, Polly Bolton, Samuel Browett, Claire Howe, Natalie Singleton, Darren Tansley & Naiara Sales
Finding more efficient ways to monitor, and estimate the diversity of, mammalian communities is a major step towards their management and conservation. Environmental DNA (eDNA) from river water has recently been shown to be a viable method for biomonitoring mammalian communities. Yet, most of the studies to date have focused on the potential for eDNA to detect individual species, with little focus on describing patterns of community diversity and structure. In this study, we focus...

Deep learning object detection to estimate the nectar sugar mass of flowering vegetation

Damien Hicks, Mathilde Baude, Christoph Kratz, Pierre Ouvrard & Graham Stone
Floral resources are a key driver of pollinator abundance and diversity, yet their quantification in the field and laboratory is laborious and requires specialist skills. Using a dataset of 25000 labelled tags of fieldwork-realistic quality, a Convolutional Neural Network (Faster R-CNN) was trained to detect the nectar-producing floral units of 25 taxa in surveyors’ quadrat images of native, weed-rich grassland in the UK. Floral unit detection on a test set of 50 model-unseen images of...

Living on the edge: Predicting invertebrate richness and rarity in disturbance-prone aquatic–terrestrial ecosystems

Kieran Gething, Chloe Hayes, Jonathan Webb, Tim Sykes, Judy England & Rachel Stubbington
1. Temporal fluctuations in water levels cause the spatial extent of wet and dry habitats to vary in aquatic–terrestrial riverine ecosystems, complicating their biomonitoring. As such, biomonitoring efforts may fail to characterise the species that inhabit such habitats, hampering assessments of their biodiversity and implementation of evidence-informed management strategies. 2. Relationships between the dynamic characteristics of aquatic-terrestrial habitats and their communities are well known. Thus, habitat characteristics may enable estimation of faunal assemblage characteristics such...
