Data from: Projected impacts of warming seas on commercially fished species at a biogeographic boundary of the European continental shelf

Katherine Maltby, Louise Rutterford, Jonathan Tinker, Martin Genner & Stephen Simpson
1. Projecting the future effects of climate change on marine fished populations can help prepare the fishing industry and management systems for resulting ecological, social and economic changes. Generating projections using multiple climate scenarios can provide valuable insights for fisheries stakeholders regarding uncertainty arising from future climate data. 2. Using a range of climate projections based on the Intergovernmental Panel on Climate Change A1B, RCP4.5 and RCP8.5 climate scenarios, we modelled abundance of eight commercially...

Reliably predicting pollinator abundance: challenges of calibrating process-based ecological models

Emma Gardner, Tom Breeze, Yann Clough, Henrik Smith, Katherine Baldock, Alistair Campbell, Michael Garratt, Mark Gillespie, William Kunin, Megan McKerchar, Jane Memmott, Simon Potts, Deepa Senapathi, Graham Stone, Felix Wäckers, Duncan Westbury, Andrew Wilby & Thomas Oliver
1. Pollination is a key ecosystem service for global agriculture but evidence of pollinator population declines is growing. Reliable spatial modelling of pollinator abundance is essential if we are to identify areas at risk of pollination service deficit and effectively target resources to support pollinator populations. Many models exist which predict pollinator abundance but few have been calibrated against observational data from multiple habitats to ensure their predictions are accurate. 2. We selected the most...

Newly discovered cichlid fish biodiversity threatened by hybridization with non-native species - Data supporting published version

Martin Genner, Tabitha Blackwell, Antonia Ford, Adam Ciezarek, Stephanie Bradbeer, Carlos Gracida-Juarez, Alan Smith, Benjamin Ngatunga, Asilatu Shechonge, Rashid Tamatamah, Graham Etherington, Wilfried Haerty, Federica Di Palma & George Turner
Invasive freshwater fish systems are known to readily hybridize with indigenous congeneric species, driving loss of unique and irreplaceable genetic resources. Here we reveal that newly discovered (2013-2016) evolutionarily significant populations of Korogwe tilapia (Oreochromis korogwe) from southern Tanzania are threatened by hybridization with the larger invasive Nile tilapia (Oreochromis niloticus). We use a combination of morphology, microsatellite allele frequencies and whole genome sequences to show that O. korogwe from southern lakes (Nambawala, Rutamba and...

Wing: A suitable non-lethal tissue type for repeatable and rapid telomere length estimates in bats

Megan L. Power, Sarahjane Power, Mads F. Bertelsen, Gareth Jones & Emma C. Teeling
Telomeres are used increasingly in ecology and evolution as biomarkers for ageing and environmental stress, and are typically measured from DNA extracted from non-lethally sampled blood. However, obtaining blood is not always possible in field conditions and only limited amounts can be taken from small mammals, such as bats, which moreover lack nucleated red blood cells and hence yield relatively low amounts of DNA. As telomere length can vary within species according to age and...

An enigmatic Neodiapsid reptile from the Middle Triassic of England

Iacopo Cavicchini, Marta Zaher & Michael James Benton
The fossil record of early diapsids is sparse, specimens are uncommon and often incomplete, and phylogenetic relationships are hard to determine. A new taxon of stem-group neodiapsid, Feralisaurus corami from the Middle Triassic of Devon, south-western England, is here named and described from an incomplete but mostly articulated skeleton, comprising skull, vertebrae, pectoral girdle, ribs and the right forelimb. CT scanning and the resultant 3D model of the skeleton reveal anatomical details otherwise buried in...

Data from: Biomechanical properties of the jaws of two species of Clevosaurus and a reanalysis of rhynchocephalian dentary morphospace

Sofia Chambi-Trowell, David Whiteside, Mike Benton & Emily Rayfield
Rhynchocephalians were a successful, globally distributed group of diapsid reptiles that thrived in the Mesozoic. Multiple species of Clevosaurus existed worldwide in the Upper Triassic and Lower Jurassic, and they are characterised by shearing bladelike teeth perhaps functionally analogous to the carnassial teeth of mammals. Morphometric analysis shows that the dentary morphospace of clevosaurs differs significantly from that of other rhynchocephalians. Five Clevosaurus species occupied islands in the Bristol Channel archipelago of the UK, but...

Categorical versus geometric morphometric approaches to characterising the evolution of morphological disparity in Osteostraci (Vertebrata, stem-Gnathostomata)

Humberto Ferron, Jenny Greenwood, Bradley Deline, Carlos Martínez Pérez, Hector Botella, Robert Sansom, Marcello Ruta & Philip Donoghue
Morphological variation (disparity) is almost invariably characterised by two non-mutually exclusive approaches: (i) quantitatively, through geometric morphometrics, and (ii) in terms of discrete, ‘cladistic’, or categorical characters. Uncertainty over the comparability of these approaches diminishes the potential to obtain nomothetic insights into the evolution of morphological disparity and the few benchmarking studies conducted so far show contrasting results. Here, we apply both approaches to characterising morphology in the stem-gnathostome clade Osteostraci in order to assess...

Small shelly fossils and carbon isotopes from the early Cambrian (Stage 3-4) Mural Formation of western Laurentia

Christian B. Skovsted, Uwe Balthasar, Jakob Vinther & Erik Sperling
The extraordinary window of phosphatised and phosphatic Small Shelly Fossils (SSFs) during the early and middle Cambrian is an important testament to the radiation of biomineralising metazoans. While SSF are well known from most Cambrian palaeocontinents during this time interval, western Laurentia has relatively few SSF faunas. Here we describe a diverse SSF fauna from the early Cambrian (Stage 3-4) Mural Formation at three localities in Alberta and British Columbia, Canada, complemented by carbon isotope...

Data from: Ecological speciation in European whitefish is driven by a large‐gaped predator

Gunnar Öhlund, Mats Bodin, Karin Nilsson, Sven-Ola Öhlund, Kenyon Mobley, Alan Hudson, Mikael Peedu, Åke Brännström, Pia Bartels, Kim Præbel, Catherine Hein, Petter Johansson & Göran Englund
Lake‐dwelling fish that form species pairs/flocks characterized by body size divergence are important model systems for speciation research. Although several sources of divergent selection have been identified in these systems, their importance for driving the speciation process remains elusive. A major problem is that in retrospect, we cannot distinguish selection pressures that initiated divergence from those acting later in the process. To address this issue, we studied the initial stages of speciation in European whitefish...

Supplemental material for: Morphological phylogenetics evaluated using novel evolutionary simulations

Joseph Keating, Robert S Sansom, Mark D Sutton, Christopher G Knight & Russell J Garwood
Evolutionary inferences require reliable phylogenies. Morphological data has traditionally been analysed using maximum parsimony, but recent simulation studies have suggested that Bayesian analyses yield more accurate trees. This debate is ongoing, in part, because of ambiguity over modes of morphological evolution and a lack of appropriate models. Here we investigate phylogenetic methods using two novel simulation models – one in which morphological characters evolve stochastically along lineages and another in which individuals undergo selection. Both...

Data from: Are British urban foxes (Vulpes vulpes) ‘bold’? The importance of understanding human-wildlife interactions in urban areas

Roberto Padovani, Zhuoyu Shi & Stephen Harris
Urban fox behaviour recorded during an extensive field experiment in Bristol, UK. We examined two different but inter-related behaviours, both of which influence a fox's propensity to take risks. Neophobia affects a fox's reaction to novelty in the environment, and wariness its reaction to potential threats. We investigated how social status and foraging social context influenced both behaviours in Bristol’s fox population. For further information please see Padovani et al. 2021.

Targeted conservation genetics of the endangered chimpanzee

Peter Frandsen, Claudia Fontsere, Sven Nielsen, Kristian Hanghøj, Natalia Castejon-Fernandez, Esther Lizano, David Hughes, Jessica Hernandez-Rodriquez, Thorfinn Korneliussen, Frands Carlsen, Hans Siegismund, Thomas Mailund, Tomas Marques Bonet & Christina Hvilsom
Populations of the common chimpanzee (Pan troglodytes) are in an impending risk of going extinct in the wild as a consequence of damaging anthropogenic impact on their natural habitat and illegal pet and bushmeat trade. Conservation management programmes for the chimpanzee have been established outside their natural range (ex situ), and chimpanzees from these programmes could potentially be used to supplement future conservation initiatives in the wild (in situ). However, these programmes have often suffered...

Nucleotide diversity of functionally different groups of immune response genes in Old World camels based on newly annotated and reference-guided assemblies

Jean Elbers, Sara Lado, Mark Rogers, José Melo-Ferreira, Jukka Corander, Petr Horin, Pamela Burger & Adiya Yadamsuren
Background Immune-response (IR) genes have an important role in the defense against highly variable pathogens, and therefore, genetic diversity in these genomic regions is essential for species’ survival and adaptation. Although current genome assemblies from Old World camelids are very useful for investigating genome-wide diversity, demography and population structure, they have inconsistencies and gaps that limit analyses at local genomic scales. Improved and more accurate genome assemblies and annotations are needed to study complex genomic...

Intrapopulation Variation in the Behavioural Responses of Dwarf Mongooses to Anthropogenic Noise

Emma Eastcott, Julie Kern, Amy Morris-Drake & Andrew Radford
Anthropogenic noise is an increasingly widespread pollutant, with a rapidly burgeoning literature demonstrating impacts on humans and other animals. However, most studies have simply considered if there is an effect of noise, examining the overall cohort response. Whilst substantial evidence exists for intraspecific variation in responses to other anthropogenic disturbances, this possibility has received relatively little experimental attention with respect to noise. Here, we used field-based playbacks with dwarf mongooses (Helogale parvula) to test how...

Data from: In situ filamentous communities from the Ediacaran (~563 Ma) of Brazil

Bruno Becker-Kerber, Gabriel De Barros, Paulo Paim, Gustavo Prado, Ana Zucatti, Abderrazak El Albani & Marc Laflamme
Precambrian filamentous microfossils are common and diverse. Nevertheless, their taxonomic assignment can be difficult due to their overall simple shapes typically lacking in diagnostic features. Here, we report in situ communities of well-preserved, large filamentous impressions from the Ediacaran Itajaí Basin (ca. 563 Ma) of Brazil. The filaments are uniserial (unbranched) and can reach up to 200 µm in width and up to 44 mm in length. They occur as both densely packed or sparsely...

Data from: Differential effects of fertilisers on pollination and parasitoid interaction networks

Edith Villa-Galaviz, Simon M. Smart, Elizabeth L. Clare, Susan E. Ward & Jane Memmott
Grassland fertilisation drives non-random plant loss resulting in areas dominated by perennial grass species. How these changes cascade through linked trophic levels, however, is not well understood. We studied how grassland fertilisation propagates change through the plant assemblage into the plant-flower visitor, plant-leaf miner and leaf miner-parasitoid networks using a year’s data collection from a long-term grassland fertiliser application experiment. Our experiment had three fertiliser treatments each applied to replicate plots 15 m2 in size:...

An effect size statistical framework for investigating sexual dimorphism in non-avian dinosaurs and other extinct taxa

Evan Saitta, Maximilian Stockdale, Nicholas Longrich, Vincent Bonhomme, Michael Benton, Innes Cuthill & Peter Makovicky
Despite reports of sexual dimorphism in extinct taxa, such claims in non-avian dinosaurs have been underrepresented recently (~the last decade) and often criticized. Since dimorphism is widespread in sexually reproducing organisms today, underrepresentation might suggest either methodological shortcomings or that this diverse group exhibited highly unusual reproductive biology. Univariate significance testing, especially for bimodality, is ineffective and prone to false negatives. Species recognition and mutual sexual selection hypotheses, therefore, may not be required to explain...

Stereo video files used for 3d tracking horsefly trajectories

Martin How & Tim Caro
Of all hypotheses advanced for why zebras have stripes, avoidance of biting fly attack receives by far the most support, yet the mechanisms by which stripes thwart landings are not yet understood. A logical and popular hypothesis is that stripes interfere with optic flow patterns needed by flying insects to execute controlled landings. This could occur through disrupting the radial symmetry of optic flow via the aperture effect (i.e. generation of false motion cues by...

Bumblebee colony density on farmland is influenced by late-summer nectar supply and garden cover

Thomas Timberlake, Ian Vaughan, Mathilde Baude & Jane Memmott
1. Floral resources are important in limiting pollinator populations, but they are often highly variable across time and space and the effect of this variation on pollinator population dynamics is not well understood. The phenology (timing) of floral resources is thought to be important in structuring pollinator populations, but few studies have directly investigated this. 2. Our study quantifies the landscape composition, seasonal nectar and pollen supply, and Bombus terrestris colony density of 12 farms...
