Data from: Independent homoploid hybrid speciation events in the Macaronesian endemic genus Argyranthemum

Oliver W. White, Alfredo Reyes-Betancort, Mark A. Chapman & Mark A. Carine
Well-characterised examples of homoploid hybrid speciation (HHS) are rare in nature yet they offer the potential to study a number of evolutionary processes. In this study we investigate putative homoploid hybrid species in the genus Argyranthemum (Asteraceae), a group of plants endemic to the Macaronesian archipelagos of the North Atlantic Ocean. We specifically address a number of knowledge gaps surrounding the origin(s) of A. sundingii and A. lemsii, which are thought to be derived from...

Data from: Plant DNA metabarcoding of lake sediments: how does it represent the contemporary vegetation

Inger Greve Alsos, Youri Lammers, Nigel Giles Yoccoz, Tina Jørgensen, Per Sjögren, Ludovic Gielly & Mary E. Edwards
Metabarcoding of lake sediments have been shown to reveal current and past biodiversity, but little is known about the degree to which taxa growing in the vegetation are represented in environmental DNA (eDNA) records. We analysed composition of lake and catchment vegetation and vascular plant eDNA at 11 lakes in northern Norway. Out of 489 records of taxa growing within 2 m from the lake shore, 17-49% (mean 31%) of the identifiable taxa recorded were...

Data from: Coupled land use and ecological models reveal emergence and feedbacks in socio‐ecological systems

Nicholas W. Synes, Calum Brown, Stephen C. F. Palmer, Greta Bocedi, Patrick E. Osborne, Kevin Watts, Janet Franklin & Justin M. J. Travis
Understanding the dynamics of socio‐ecological systems is crucial to the development of environmentally sustainable practices. Models of social or ecological sub‐systems have greatly enhanced such understanding, but at the risk of obscuring important feedbacks and emergent effects. Integrated modelling approaches have the potential to address this shortcoming by explicitly representing linked socio‐ecological dynamics. We developed a socio‐ecological system model by coupling an existing agent‐based model of land‐use dynamics and an individual‐based model of demography and...

Johanna Junker, Valerie Brandt, Brian D. Berman, Marie Vidailhet, Emmanuel Roze, Anne Weissbach, Cynthia Comella, Irene A. Malaty, Joseph Jankovic, Mark S. LeDoux, Alfredo Berardelli, Richard Barbano, Stephen G. Reich, Joel S. Perlmutter, Hyder A. Jinnah & Norbert Brüggemann
Objective: To determine predictors of alcohol responsiveness in a large cohort of dystonia patients. Methods: 2159 participants with dystonia were prospectively enrolled in the cross-sectional Dystonia Coalition multicenter study. Patients with secondary, combined or confirmed genetic dystonia (total n=164) or unknown alcohol responsiveness (n= 737) were excluded. Patients answered a standardized questionnaire and were clinically examined using a standardized video protocol and the Burke-Fahn-Marsden Dystonia Rating Scale. Alcohol responsiveness was determined by patients’ self-report. Results:...

Data from: The consequences of daily cyclic hypoxia on a European grass shrimp: from short-term responses to long-term effects

Luca Peruzza, Marco Gerdol, Andrew Oliphant, David Wilcockson, Alberto Pallavicini, Lawrence Hawkins, Sven Thatje & Chris Hauton
1. Salt marshes are a key coastal environment for their important role as nursery habitats for marine and estuarine fish and crustaceans. Salt marshes are variable environments where species can experience daily cyclic hypoxic stress, characterized by profound variations in oxygen partial pressure (pO2) from supersaturated conditions (~42kPa) to extremely hypoxic conditions (~3kPa) in ~12-hours. 2. Here, under laboratory conditions, we assessed the physiological consequences of exposing the shrimp Palaemon varians, a species commonly found...

Data from: The architecture of an empirical genotype-phenotype map

Jose Aguilar-Rodriguez, Leto Peel, Massimo Stella, Andreas Wagner & Joshua L. Payne
Recent advances in high-throughput technologies are bringing the study of empirical genotype-phenotype (GP) maps to the fore. Here, we use data from protein binding microarrays to study an empirical GP map of transcription factor (TF) binding preferences. In this map, each genotype is a DNA sequence. The phenotype of this DNA sequence is its ability to bind one or more TFs. We study this GP map using genotype networks, in which nodes represent genotypes with...

Data from: Comparative population genomics reveals key barriers to dispersal in Southern Ocean penguins

Gemma V. Clucas, Jane L. Younger, Damian Kao, Louise Emmerson, Colin Southwell, Barbara Wienecke, Alex D. Rogers, Charles-Andre Bost, Gary D. Miller, Michael J. Polito, Patrick Lelliot, Jonathan Handley, Sarah Crofts, Richard A. Phillips, Michael J. Dunn, Karen J. Miller, Tom Hart & Patrick Lelliott
The mechanisms that determine patterns of species dispersal are important factors in the production and maintenance of biodiversity. Understanding these mechanisms helps to forecast the responses of species to environmental change. Here we used a comparative framework and genome-wide data obtained through RAD-seq to compare the patterns of connectivity among breeding colonies for five penguin species with shared ancestry, overlapping distributions, and differing ecological niches, allowing an examination of the intrinsic and extrinsic barriers governing...

Data from: Recording and reproducing the diurnal oviposition rhythms of wild populations of the soft- and stone- fruit pest Drosophila suzukii

Bethan Shaw, Fountain T. Michelle, Wijnen Herman & Herman Wijnen
Drosophila suzukii is a horticultural pest on a global scale which causes both yield and economic losses on a range of soft- and stone-fruit. Tackling this pest is problematic but exploiting behavioural rhythms could increase the impact of control. To do this, a better understanding of behavioural patterns is needed. Within this study we aimed to investigate rhythms in reproductive behaviour of wild D. suzukii under natural conditions in the field. Environmental parameters were also...

Data from: Does postcranial palaeoneurology provide insight into pterosaur behaviour and lifestyle? New data from the azhdarchoid Vectidraco and the ornithocheirids Coloborhynchus and Anhanguera

Elizabeth Martin-Silverstone, Daniel Sykes & Darren Naish
The postcranial palaeoneurology of fossil reptiles is understudied, and those studies that exist focus predominantly on crocodyliforms and dinosaurs. The intervertebral foramina of the spine house nerves that exit to innervate surrounding tissues and the extremities. In the heavily fused (and typically distorted or poorly preserved) pterosaurian sacrum, intervertebral foramina can be difficult to observe and are rarely identified. The Early Cretaceous azhdarchoid Vectidraco from the Isle of Wight, UK, exhibits large, paired foramina on...

Data from: Mutation in the intracellular chloride channel CLCC1 associated with autosomal recessive retinitis pigmentosa

Lin Li, Xiaodong Jiao, Ilaria D’Atri, Fumihito Ono, Ralph Nelson, Chi-Chao Chan, Naoki Nakaya, Zhiwei Ma, Yan Ma, Xiaoying Cai, Longhua Zhang, Siying Lin, Abdul Hameed, Barry A. Chioza, Holly Hardy, Gavin Arno, Sarah Hull, Muhammad Imran Khan, James Fasham, V. Gaurav Harlalka, Michel Michaelides, Anthony T. Moore, Zeynep Hande Coban Akdemir, Shalini Jhangiani, James R. Lupski … & Frans P. M. Cremers
We identified a homozygous missense alteration (c.75C>A, p.D25E) in CLCC1, encoding a presumptive intracellular chloride channel highly expressed in the retina, associated with autosomal recessive retinitis pigmentosa (arRP) in eight consanguineous families of Pakistani descent. The p.D25E alteration decreased CLCC1 channel function accompanied by accumulation of mutant protein in granules within the ER lumen, while siRNA knockdown of CLCC1 mRNA induced apoptosis in cultured ARPE-19 cells. TALEN KO in zebrafish was lethal 11 days post...

Data from: Contrasting genetic structure of sympatric congeneric gastropods: do differences in habitat preference, abundance, and distribution matter?

Edward J.G. Wort, Mark A. Chapman, Stephen John Hawkins, Lucy Henshall, Alfonso Pita, Marc Rius, Suzanne T. Williams & Phillip B. Fenberg
Aim: The relationship of population genetics with the ecology and biogeography of species may be explored by comparing phenotypically similar but ecologically different congeners with overlapping ranges. We compared genetic differentiation between two congeneric rocky intertidal gastropods across a major portion of their sympatric range. We hypothesized that the habitat generalist with high abundance and continuous distribution would exhibit comparatively less genetic differentiation than the habitat specialist with low abundance and a fragmented distribution. Location:...

Data from: Positive effects of liana cutting on seedlings are reduced during El Niño-induced drought

Michael J. O'Brien, Christopher D. Philipson, Glen Reynolds, Dzaeman Dzulkifli, Jake L. Snaddon, Robert Ong & Andy Hector
1. Liana cutting is a management practice currently applied to encourage seedling regeneration and tree growth in some logged tropical forests. However, there is limited empirical evidence of its effects on forest demographic rates in Southeast Asia. 2. We used 22 four-hectare plots in the Sabah Biodiversity Experiment (a reduced impact logging site) enrichment line planted with 16 dipterocarp species to assess the effects of complete liana cutting on tree growth and survival. We compared...

Data from: Spatiotemporal incidence of Zika and associated environmental drivers for the 2015-2016 epidemic in Colombia

Amir S. Siraj, I. Rodriguez-Barraquer, Christopher M. Barker, Natalia Tejedor-Garavito, Dennis Harding, Christopher Lorton, Dejan Lukacevic, Gene Oates, Guido Espana, Moritz U. G. Kraemer, Carrie Manore, Michael A. Johansson, Andrew J. Tatem, Robert C. Reiner & T. Alex Perkins
Despite a long history of mosquito-borne virus epidemics in the Americas, the impact of the Zika virus (ZIKV) epidemic of 2015-2016 was unexpected. The need for scientifically informed decision-making is driving research to understand the emergence and spread of ZIKV. To support that research, we assembled a data set of key covariates for modeling ZIKV transmission dynamics in Colombia, where ZIKV transmission was widespread and the government made incidence data publically available. On a weekly...

Data from: Clitellate worms (Annelida) in lateglacial and Holocene sedimentary DNA records from the Polar Urals and northern Norway

Youri Lammers, Charlotte L. Clarke, Christer Erséus, Antony G. Brown, Mary E. Edwards, Ludovic Gielly, Haflidi Haflidason, Jan Mangerud, Emilia Rota, John Inge Svendsen & Inger Greve Alsos
While there are extensive macro- and microfossil records of a range of plants and animals from Quaternary records, earthworms and their close relatives among annelids are not preserved as fossils, and therefore we have limited knowledge of their Quaternary distributions. This lack of fossils means that clitellate worms (Annelida) are currently underused in palaeoecological research, even though they can provide valuable information about terrestrial and aquatic environmental conditions. Their DNA might be preserved in sediments,...

Data from: Queen longevity and fecundity affect conflict with workers over resource inheritance in a social insect

Edward J. Almond, Timothy J. Huggins, Liam P. Crowther, Joel D. Parker & Andrew F. G. Bourke
Resource inheritance is a major source of conflict in animal societies. However, the assumptions and predictions of models of conflict over resource inheritance have not been systematically tested within a single system. We developed an inclusive fitness model for annual eusocial Hymenoptera that predicts a zone of conflict in which future reproductive workers are selected to enforce nest inheritance before the queen is selected to cede the nest. We experimentally tested key elements of this...

Data from: The role of climate, water and biotic interactions in shaping biodiversity patterns in arid environments across spatial scales

Orly Razgour, Mike Persey, Uzi Shamir & Carmi Korine
Aim: Desert ecosystems, with their harsh environmental conditions, hold the key to understanding the responses of biodiversity to climate change. As desert community structure is influenced by processes acting at different spatial scales, studies combining multiple scales are essential for understanding the conservation requirements of desert biota. We investigated the role of environmental variables and biotic interactions in shaping broad and fine-scale patterns of diversity and distribution of bats in arid environments to understand how...

Data from: Immediate impact of a hurricane on the structure of a tropical butterfly community

Frances Mullany, Georgina Hollands & Jake L. Snaddon
More intense and frequent hurricanes may lead to long-lasting effects to tropical ecosystems. Here we describe the immediate impact on the butterfly community of a lowland forest in Belize, following Hurricane Earl. Species richness and abundance increased post-hurricane, likely driven by convergence of the organisation between the canopy and understory communities.
