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...

Primer biases in the molecular assessment of diet in multiple insectivorous mammals

Samuel Browett, Thomas Curran, Denise O'Meara, Andrew Harrington, Naiara Guimarães Sales, Rachael Antwis, David O'Neill & Allan McDevitt
Our understanding of trophic interactions of small insectivorous mammals has been drastically improved with the advent of DNA metabarcoding. The technique has continued to be optimised over the years, with primer choice repeatedly being a vital factor for dietary inferences. However, the majority of dietary studies examining the effect of primer choice often rely on in silico analyses or comparing between species that occupy an identical niche type. Here we apply DNA metabarcoding to empirically...

Parallel evolution of Varroa resistance in honey bees; a common mechanism across continents?

Isobel Grindrod & Stephen Martin
The near-globally distributed ecto-parasitic mite of the Apis mellifera honey bee, Varroa destructor, has formed a lethal association with Deformed wing virus, a once rare and benign RNA virus. In concert the two have killed millions of wild and managed colonies, particularly across the northern hemisphere, forcing the need for regular acaricide application to ensure colony survival. However, despite the short association (in evolutionary terms), A. mellifera populations across the globe have been surviving many...

Soil and vegetation radionuclide activity concentrations and calculated dose rates from the Red Forest, Chernobyl, Ukraine, 2016-2017

C.L. Barnett, S. Gashchak, A. Maksimenko, J.S. Chaplow, M.D. Wood & N.A. Beresford
Data comprise plot details and radionuclide activity concentrations for Sr-90, Cs-137, Am-241, Pu-238, Pu-239 and Pu-240 in ‘grassy’ vegetation and soil. These radionuclide activity concentrations have been used to make estimations of total weighted absorbed doses to grassy vegetation, deciduous trees and bacteria; no dose rate estimates for grassy vegetation have been made for those sites where grassy vegetation was absent. Radiation from the 1986 Chernobyl nuclear power plant accident killed coniferous trees in a...

Optimising bat bioacoustic surveys in human-modified neotropical landscapes

Adrià López-Baucells, Natalie Yoh, Ricardo Rocha, Paulo Bobrowiec, Jorge Palmeirim & Christoph Meyer
During the last decades, the use of bioacoustics as a non-invasive and cost-effective sampling method has greatly increased worldwide. For bats, acoustic surveys have long been known to complement traditional mist-netting, however, appropriate protocol guidelines are still lacking for tropical regions. Establishing the minimum sampling effort needed to detect ecological changes in bat assemblages (e.g., activity, composition and richness) is crucial in view of workload and project cost constraints, and because detecting such changes must...

Data from: Widespread loss of mammalian lineage and dietary diversity in the early Oligocene of Afro-Arabia

Dorien De Vries, Steven Heritage, Matthew Borths, Hesham Sallam & Erik Seiffert
Diverse lines of geological and geochemical evidence indicate that the Eocene-Oligocene transition (EOT) marked the onset of a global cooling phase, rapid growth of the Antarctic ice sheet, and a worldwide drop in sea level. Paleontologists have established that shifts in mammalian community structure in Europe and Asia were broadly coincident with these events, but the potential impact of early Oligocene climate change on the mammalian communities of Afro-Arabia has long been unclear. Here we...

Bat phylogenetic responses to regenerating Amazonian forests

Fábio Z. Farneda, Ricardo Rocha, Sabhrina Gita Aninta, Adrià López-Baucells, Erica M. Sampaio, Jorge M. Palmeirim, Paulo E. D. Bobrowiec, Cristian S. Dambros & Christoph F. J. Meyer
1. Throughout the tropics, regenerating secondary forests occupy vast areas previously cleared for agriculture and cattle ranching. However, despite the importance of regenerating forests in mitigating the pervasive negative consequences of forest loss and fragmentation on forest-associated biodiversity, longitudinal studies on species’ phylogenetic responses to matrix regeneration are rare. 2. We surveyed bats in continuous primary forest, primary forest fragments and in the regenerating secondary forest matrix of a whole-ecosystem Amazonian fragmentation experiment, ~15 and...

Soil biological activity in the Chernobyl Exclusion Zone, Ukraine, September 2005 and spring 2016

C.L. Barnett, S. Gashchak, C. Wells, A. Maksimenko, J. Chaplow, M.D. Wood, N.R. Parekh & N.A. Beresford
Data comprise site location, soil chemistry (pH, soil moisture), soil radionuclide activity concentrations (the isotopes measured were: Americium-241, Caesium-137, Plutonium-238, -239 and -240, Strontium-90 (K-40 and U-238 activity concentrations were estimated from stable element data) and soil biological activity (derived from application of bait lamina sticks) at 18 sites in the Chernobyl Exclusion Zone (CEZ), Ukraine in 2016; data for four sites in 2005 are also presented. Estimate absorbed radionuclide dose rates to soil invertebrates...

eDNA in a bottleneck: obstacles to fish metabarcoding studies in megadiverse freshwater systems

Jake Jackman, Chiara Benvenuto, Ilaria Coscia, Cintia Carvalho, Jonathan Ready, Jean Boubli, William Magnusson, Allan McDevitt & Naiara Sales
The current capacity of environmental DNA (eDNA) to provide accurate insights into the biodiversity of megadiverse regions (e.g., the Neotropics) requires further evaluation to ensure its reliability for long-term monitoring. In this study, we first evaluated the taxonomic resolution capabilities of a short fragment from the 12S rRNA gene widely used in fish eDNA metabarcoding studies, and then compared eDNA metabarcoding data from water samples with traditional sampling using nets. For the taxonomic discriminatory power...
