Echolocating toothed whales use ultra-fast echo-kinetic responses to track evasive prey

Heather Vance, Peter Madsen, Natacha Aguilar De Soto, Danuta Wisniewska, Michael Ladegaard, Sascha Hooker & Mark Johnson
Visual predators rely on fast-acting optokinetic responses to track and capture agile prey. Most toothed whales, however, rely on echolocation for hunting and have converged on biosonar clicking rates reaching 500/s during prey pu rsuits. If echoes are processed on a click by click basis, as assumed, neural responses 100x faster than those in vision are required to keep pace with this information flow. Using high resolution bio-logging of wild predator prey interactions we show...

ARISE project - Work package 3: Stable nitrogen isotopes of bulk tissue and amino-acids of ringed seals muscle and teeth's growth layer groups of harp seals from the Arctic and sub-Arctic

Camille de la Vega, Joanna Kershaw, David J Yurkowski, Steven H Ferguson, Garry B Stenson, Tore Haug, Martin Biuw, Anne K Frie, Sophie C Smout, Rachel M Jeffreys & Claire Mahaffey
This dataset includes stable nitrogen isotopes of bulk tissue (δ15Nbulk) and compound specific stable nitrogen isotopes on amino acids (δ15NAA) measured in harp seal (Pagophilus groenlandicus) teeth from Southern Barents Sea, Greenland Sea, Northwest Atlantic, and ringed seal (Pusa hispida) muscles from Canadian Arctic Archipelago and Baffin Island, in the Arctic and sub-Arctic. Teeth of harp seals from the Northwest Atlantic (n=48) were taken from archives in Fisheries and Oceans Canada (DFO) St John's, Canada...

Adverse positioning in mammography - observations of imaging features

Patsy Whelehan
This dataset consists of observations of mammographic images, plus three relevant variables used in the validation process for the measure of adverse positioning we developed based on the dataset. An expert observer generated the primary data by reviewing mammographic images to judge the presence or absence of a set of features developed through theory and consultation with other experts. The data can be reused by anyone wishing to learn and practice psychometric validation techniques, for...

Cetacean sightings from the British Antarctic Survey CCAMLR synoptic krill survey of South Georgia and the South Sandwich Islands, January to February 2019

Mick Baines, Maren Reichelt, Claire Lacey, Simon Pinder, Sophie Fielding & Jennifer A Jackson
Cetacean sightings in South Georgia and South Sandwich Islands waters, made by a team of four professional marine mammal observers during the British Antarctic Survey CCAMLR synoptic krill survey on the RRS James Cook (DY098), January and February 2019. The latitude and longitude of each sighting, the identified species, bearing and distance from the vessel, and estimated group size are provided. These data have been used by BAS to estimate (i) humpback whale and (ii)...

The value of considering demographic contributions to connectivity - a review

Joseph Drake, Xavier Lambin & Christopher Sutherland
Connectivity is a central concept in ecology, wildlife management and conservation science. Understanding the role of connectivity in determining species persistence is increasingly important in the face of escalating anthropogenic impacts on climate and habitat. These connectivity augmenting processes can severely impact species distributions and community and ecosystem functioning. One general definition of connectivity is an emergent process arising from a set of spatial interdependencies between individuals or populations, and increasingly realistic representations of connectivity...

Data Collected During Simultaneous Neutron Powder Diffraction and Microwave Characterisation at Elevated Temperatures

Michael Barter, Gemma Smith, Sihai Yang, Martin Schröder, Martin Owen Jones & Adrian Porch
This dataset contains data collected during simultaneous neutron diffraction and microwave characterisation of a metal-organic framework (MOF), MFM-170, at elevated temperatures. The experiment consisted of the desolvation of the as synthesised MOF sample by flowing nitrogen gas heated to 150 °C through the sample, followed by rehydration of the sample by flowing air through the sample, and subsequent desolvation at a higher flow rate. Temperatures throughout the experiment are given (time and temperature) along with...

Data from: DNA barcoding identifies cryptic animal tool materials

Linda Neaves, Matthew Steele, Barbara Klump, James St Clair, Joana Fernandes, Vanessa Hequet, Phil Shaw, Christian Rutz & Peter Hollingsworth
Some animals fashion tools and other constructions out of plant materials to aid foraging, reproduction, self-maintenance, and protection. The choice of raw materials can affect the structure and mechanical properties of the resulting artefacts, with significant fitness consequences. Documenting animals’ material preferences is challenging, however, as manufacture behaviour is often difficult to observe directly, and materials may be processed so heavily that they lack identifying features. Here, we use DNA barcoding techniques to identify, from...

Data from: Chimpanzees behave prosocially in a group-specific manner

Edwin J. C. Van Leeuwen, Sarah E. DeTroy, Stephan P. Kaufhold, Clara Dubois, Sebastian Schütte, Josep Call & Daniel B. M. Haun
Chimpanzees act cooperatively in the wild, but whether they afford benefits to others, and whether their tendency to act prosocially varies across communities is unclear. Here, we show that chimpanzees from neighboring communities provide valuable resources to group members at personal cost, and that the magnitude of their prosocial behavior is group specific. Provided with a resource-donation experiment allowing for free (partner) choice, we observed an increase in prosocial acts across the study period in...

Data from: Targeted Helping and Cooperation in Zoo-living Chimpanzees and Bonobos

Suska Nolte & Josep Call
Directly comparing the behaviour of our two closest living relatives, chimpanzees and bonobos, during prosocial tasks is essential to deepen our understanding about the evolution of human prosociality. We examined whether helpers of six dyads of chimpanzees and bonobos transferred tools to a conspecific. In experiment ‘Helping’, transferring a tool did not benefit the helper while in experiment ‘Cooperation’ the helper only obtained a reward by transferring the correct tool. Chimpanzees did not share tools...

Habitat mediates coevolved but not novel species interactions

Joshua Twining, Chris Sutherland, Neil Reid & David Tosh
On-going recovery of native predators has the potential to alter species interactions, with community and ecosystem wide implications. We estimated co-occurrence of three species of conservation and management interest from a multi-species citizen science camera trap survey. We demonstrate fundamental differences in novel and co-evolved predator-prey interactions that are mediated by habitat. Specifically, we demonstrate that anthropogenic habitat modification had no influence on the expansion of the recovering native pine marten in Ireland, nor does...

Camera traps Red deer exhibit spatial and temporal responses to hiking activity

Solene Marion
Outdoor recreation has the potential to impact the spatial and temporal distribution of animals. We explore interactions between red deer (Cervus elaphus) and hikers along a popular hiking path in the Scottish Highlands. We placed camera traps in transects at different distances (25, 75 and 150 metres) from the path to study whether distance from hiker activity influences the number of deer detected. We compared this with the detection of red deer in an additional,...

Visual discomfort and variations in chromaticity in art and nature

Olivier Penacchio, Sarah Haigh, Xortia Ross, Rebecca Ferguson & Arnold Wilkins
Visual discomfort is related to the statistical regularity of visual images. The contribution of luminance contrast to visual discomfort is well understood and can be framed in terms of a theory of efficient coding of natural stimuli, and linked to metabolic demand. While colour is important in our interaction with nature, the effect of colour on visual discomfort has received less attention. In this study, we build on the established association between visual discomfort and...

Data on spin-singlet to triplet Cooper pair converter interface

Matthew Rogers, A. Walton, Machiel Geert Flokstra, R. Stewart, Stephen Lee, Thomas Prokscha, A.J. Caruana, C.J. Kinane, Sean Langridge, Fatma Al Ma'Mari, H. Bradshaw, Timothy Moorsom, M. Ali, Gavin Burnell, B J Hickey & Oscar Cespedes
This dataset contains the measurements reported in the manuscript "Spin-singlet to triplet Cooper pair converter interface". In this study, we fuse magnetism and superconductivity in a system where spin-ordering and diffusion of Cooper pairs are achieved at a non-intrinsically magnetic nor superconducting Cu/C60 interface. Electron transport, magnetometry and low-energy muon spin rotation are used to probe time-reversal symmetry breaking in these structures.

The dataset comprises of physical property and biogeochemical measurements of saltmarsh soil collected using the hammer coring technique from the Kyle of Tongue saltmarsh in the North of Scotland. The site was chosen to represent northern, loch head marshes and to test different coring techniques in organic rich soils. The data provides a quantitative measure of the dry bulk density, water content, porosity and organic carbon content present within the soils of the Kyle of...

Estimating on the fly: the approximate number system in rufous hummingbirds (Selasphorus rufus)

Mia Corliss, Theo Brown, T. Andrew Hurly, Susan D. Healy & Maria C. Tello-Ramos
When presented with resources that differ in quantity, many animals use a numerosity system to discriminate between them. One taxonomically widespread system is the approximate number system. This is a numerosity system that allows the rapid evaluation of the number of objects in a group and which is regulated by Weber’s Law. Here we investigated whether wild, free-living rufous hummingbirds (Selasphorus rufus) possess an approximate number system. The hummingbirds were presented with two experiments. In...

Life‐stage‐dependent supergene haplotype frequencies and metapopulation neutral genetic patterns of Atlantic cod, Gadus morhua, from Canada's Northern cod stock region and adjacent areas

Gregory Puncher, Sherrylynn Rowe, George A. Rose, Geneviève J. Parent, Yanjun Wang & Scott A. Pavey
Among highly migratory fish species, nursery areas occupied by juveniles often differ from adult habitats. To better understand the spatial dynamics of Canada’s Northern cod stock, juveniles caught off the east coast of Newfoundland and Labrador were compared to adults from the same region as well as individuals from other areas in Atlantic Canada using ddRAD-derived SNPs. A reduced proportion of homozygotes with a chromosomal inversion located in LG1 was detected between juvenile and adult...

Oxygen measurements in closed system respirometry using blubber explants from suckling and fasting grey seal pups

Kelly Robinson, Kimberley Bennett & Ailsa Hall
Understanding physiological responses of wildlife and domesticated animals to environmental challenges can be difficult or impossible to investigate at the whole animal level. Tissue culture approaches open up experimental possibilities, but are difficult to undertake in remote environments where facilities to assess tissue viability and minimise or monitor microbial contamination may not be available. Here we used planar optodes in closed system respirometry to measure oxygen use by blubber explants from grey seal (Halichoerus grypus)...

The Non-Human Agency of a Thing in 'Orendel or The Grey Robe'

Bettina Bildhauer
An emerging research consensus on Orendel or the Grey Robe has begun to consider the seamless tunic of Christ to be of central importance for this text, and to suggest that the narrative should be considered a thing biography of this robe rather than as a bridal quest epic focusing on a human protagonist. This article furthers this interpretation by analyzing the way in which the narrative suggests that the robe as a protagonist has...

Speciation in the abyss - genomics and morphology reveal a new species of beaked whale

Emma L. Carroll, Michael R. McGowen, Morgan L. McCarthy, Felix G. Marx, Natacha Aguilar De Soto, Merel L. Dalebout, Sascha Dreyer, Oscar E. Gaggiotti, Sabine S. Hansen, Anton Van Helden, Aubrie B. Onoufriou, Robin W. Baird, C. Scott Baker, Simon Berrow, Danielle Cholewiak, Diane Claridge, Rochelle Constantine, Nicholas J. Davison, Catarina Eira, R. Ewan Fordyce, John Gatesy, G. J. Greg Hofmeyr, Vidal Martin, James G. Mead, Antonio A. Mignucci-Giannoni … & Morten T. Olsen
Earth’s deep oceans remains less well understood than the surface of Mars. Beaked whales (ziphiids) are among the most visible inhabitants of the abyss, due to their large size and worldwide distribution, yet their diversity and ecology remain obscure. We combine genomic and morphometric analyses to reveal a new Southern Hemisphere ziphiid species, Ramari’s beaked whale, Mesoplodon eueu, whose name is linked to the Indigenous people of the lands from which the species holotype and...

Mesocarnivore community structuring in the presence of Africa’s apex predator

Gonçalo Curveira-Santos, Chris Sutherland, Simone Tenan, Albert Fernández-Chacón, Gareth Mann, Ross Pitman & Lourens Swanepoel
Apex predator reintroductions have proliferated across southern Africa, yet their ecological effects and proposed umbrella benefits of associated management lack empirical evaluations. Despite a rich theory on top-down ecosystem regulation via mesopredator (<20kg) suppression, a knowledge gap exists relating to the influence of lions (Panthera leo) over Africa’s diverse mesocarnivore communities. We investigate how geographical variation in mesocarnivore community richness and occupancy across South African reserves is associated with the presence of lions. An interesting...

Source data and code for: Climate change transforms the functional identity of Mediterranean coralligenous assemblages

Daniel Gómez-Gras, Cristina Linares, Maria Dornelas, Joshua S. Madin, Viviana Brambilla, Jean-Baptiste Ledoux, Nathaniel Bensoussan, Paula López-Sendino & Joaquim Garrabou
We used five long-term (>10 years) records of Mediterranean coralligenous assemblages in a multi-taxa, trait-based analysis to investigate MHW-driven changes in functional structure. We show that, despite stability in functional richness (i.e., the range of species functional traits), MHW-impacted assemblages experienced long-term directional changes in functional identity (i.e., their dominant trait values). Declining traits included large sizes, long lifespans, arborescent morphologies, filter feeding strategies or calcified skeletons. These traits, which were mostly supported by few...
