Fine-scale seascape genomics of an exploited marine species, the common cockle Cerastoderma edule, using a multi-modelling approach

Ilaria Coscia, Sophie Wilmes, Joseph Ironside, Goward-Brown Alice, Enda O'Dea, Shelagh Malham, Allan McDevitt & Peter Robins
Population dynamics of marine species that are sessile as adults are driven by oceanographic dispersal of larvae from spawning to nursery grounds. This is mediated by life-history traits such as the timing and frequency of spawning, larval behaviour and duration, and settlement success. Here, we use 1725 single nucleotide polymorphisms (SNPs) to study the fine scale spatial genetic structure in the commercially important cockle species Cerastoderma edule and compare it to environmental variables and current-mediated...

The Influence of Environmental Variation on the Genetic Structure of a Poison Frog Distributed Across Continuous Amazonian Rainforest

Anthony Ferreira, Albertina Lima, Robert Jehle, Miquéias Ferrão & Adam Stow
Biogeographic barriers such as rivers have been shown to shape spatial patterns of biodiversity in the Amazon basin, yet relatively little is known about the distribution of genetic variation across continuous rainforest. Here, we characterize the genetic structure of the brilliant-thighed poison frog (Allobates femoralis) across an 880-km-long transect along the Purus-Madeira interfluve south of the Amazon river, based on 64 individuals genotyped at 7609 single-nucleotide polymorphism loci. A population tree and clustering analyses revealed...

Data from: All is fish that comes to the net: metabarcoding for rapid fisheries catch assessment

Lorenzo Talarico, Tommaso Russo, Giulia Maiello, Charles Baillie, Giuliano Colosimo, Lorenzo D'Andrea, Federico Di Maio, Fabio Fiorentino, Simone Franceschini, Germana Garofalo, Dario Scannella, Stefano Cataudella & Stefano Mariani
AbstractMonitoring marine resource exploitation is a key activity in fisheries science and biodiversity conservation. Since research surveys are time-consuming and costly, fishery-dependent data (i.e. derived directly from fishing vessels) are increasingly credited with a key role in expanding the reach of ocean monitoring. Fishing vessels may be seen as widely ranging data-collecting platforms, which could act as a fleet of sentinels for monitoring marine life, in particular exploited stocks. Here, we investigate the possibility of...

Embedding Life Cycle Costing in 5D BIM

Dermot Kehily & Jason Underwood
Life Cycle Costing (LCC) is the consideration of all ‘relevant’ costs and revenues associated with the acquisition and ownership of an asset. LCC has a number of relevant applications, these include project appraisal; facilities management; procurement and tendering and as a means to evaluate sustainable construction. Although these advantages are well recognised, the process is underutilised due to a number of documented barriers to adoption. Notably these include lack of accurate historical databases; the perceived...

Environmental DNA effectively captures functional diversity of coastal fish communities

Giorgio Aglieri, Charles Baillie, Stefano Mariani, Carlo Cattano, Antonio Calò, Gabriele Turco, Davide Spatafora, Antonio Di Franco, Manfredi Di Lorenzo, Paolo Guidetti & Marco Milazzo
Robust assessments of taxonomic and functional diversity are essential components of research programs aimed at understanding current biodiversity patterns and forecasting trajectories of ecological changes. Yet, evaluating marine biodiversity along its dimensions is challenging and dependent on the power and accuracy of the available data collection methods. Here we combine three traditional survey methodologies [Underwater Visual Census strip transects (UVCt), Baited Underwater Videos (BUVs) and Small Scale Fishery catches (SSFc)], and one novel molecular technique...

Acoustic and temporal birdsong measurements

Tristan Kleyn, Mariane Da Cruz Kaizer & Luiza Figueiredo Passos
In tropical birds, survival is dependent on the ability to effectively communicate with others against a background of high ambient noise. The Acoustic Niche Hypothesis proposes that the deterrent selective force of signal masking has caused animals sharing a habitat to partition their calling behaviour amongst the acoustic bandwidths available, so as to minimise interference between one another. Whether and why species share the so-called ‘acoustic space’ remains a gap in our understanding of animal...

Influence of preservation methods, sample medium and sampling time on eDNA recovery in a neotropical river

Naiara Sales, Owen S. Wangensteen, Daniel Carvalho & Stefano Mariani
Environmental DNA (eDNA) has rapidly emerged as a promising biodiversity monitoring technique, proving to be a sensitive and cost‐effective method for species detection. Despite the increasing popularity of eDNA, several questions regarding its limitations remain to be addressed. We investigated the effect of sampling me‐ dium and time, and preservation methods, on fish detection performance based on eDNA metabarcoding of neotropical freshwater samples. Water and sediment sam‐ ples were collected from 11 sites along the...

A co-development approach to conservation leads to informed habitat design and rapid establishment of amphibian communities

David O'Brien, Jeanette Hall, Alexandre Miró, Katie O'Brien & Robert Jehle
1. Effective wildlife restoration is a critical requirement of many conservation actions. The outcome of conservation interventions can be optimised through knowledge of species’ habitat requirements, but few studies consider the impact of using explicit evidence from dedicated local research to inform the design phase of habitat management. Furthermore, interventions administered externally from the top down, whilst simpler than those developed in discussion with multiple stakeholders including land managers (i.e. co-development), run the risk of...

Design Science: Choosing an appropriate methodology for research in BIM

Dermot Kehily & Jason Underwood
This paper discusses Building Information Modelling (BIM) in relation to proposing design science as a methodology for BIM research. The paper firstly outlines how BIM is changing construction work practices to a more collaborative and integrated set of procedures, facilitated through the application of modelling technologies. The use of traditional research methods for BIM research in the context of developing and subsequently evaluating a BIM process or technology is then questioned. The premise of this...

Stable species boundaries despite ten million years of hybridization in tropical eels

Julia Barth, Chrysoula Gubili, Michael Matschiner, Ole Tørresen, Shun Watanabe, Bernd Egger, Yu-San Han, Eric Feunteun, Ruben Sommaruga, Robert Jehle & Robert Schabetsberger
Genomic evidence is increasingly underpinning that hybridization between taxa is commonplace, challenging our views on the mechanisms that maintain their boundaries. Here, we focus on seven catadromous eel species (genus Anguilla), and use genome-wide sequence data from more than 450 individuals sampled across the tropical Indo-Pacific, morphological information, and three newly assembled draft genomes to compare contemporary patterns of hybridization with signatures of past gene flow across a time-calibrated phylogeny. We show that the seven...

Fishing for mammals: landscape-level monitoring of terrestrial and semi-aquatic communities using eDNA from lotic ecosystems

Naiara Sales, Maisie B. McKenzie, Joseph Drake, Lynsey R. Harper, Samuel S. Browett, Ilaria Coscia, Owen S. Wangensteen, Charles Baillie, Emma Bryce, Deborah A. Dawson, Erinma Ochu, Bernd Hänfling, Lori Lawson Handley, Stefano Mariani, Xavier Lambin, Christopher Sutherland & Allan McDevitt
1. Environmental DNA (eDNA) metabarcoding has revolutionised biomonitoring in both marine and freshwater ecosystems. However, for semi-aquatic and terrestrial animals, the application of this technique remains relatively untested. 2. We first assess the efficiency of eDNA metabarcoding in detecting semi-aquatic and terrestrial mammals in natural lotic ecosystems in the UK by comparing sequence data recovered from water and sediment samples to the mammalian communities expected from historical data. Secondly, using occupancy modelling we compared the...
