Plant biodiversity data and environmental and spatial data from Jebel Ichkeul, a limestone mountain in northern Tunisia (1983)

D.A. Kirk, K. Hébert & F. B. Goldsmith
Records for herbaceous and woody plants at 78 nested quadrats on a limestone mountain (Jebel Ichkeul) in Le Parc National de L’Ichkeul are presented. Data for plants represent percent cover (Braun-Blanquet scale), to identify environmental gradients and investigate phytosociology of plant communities. Environmental variables are also presented: altitude, slope, aspect, rock out cropping, index of grazing intensity (78 sites) and olive tree densities by size class (69 sites). Soil pH was collected for 50 sites....

Unresolved–disorganized attachment adjusted for a general psychopathology factor associated with atypical amygdala resting-state functional connectivity

Marie-José van Hoof, Madelon M. E. Riem, Amy S. Garrett, Nic J. A. van der Wee, Marinus H. van IJzendoorn & Robert R. J. M Vermeiren
Background: Recent research has identified a general psychopathology factor (GPF), which explains overlap in presentation of psychopathological symptoms. Unresolved–disorganized attachment (Ud) is another transdiagnostic risk factor that may be relevant to explain differences in patient characteristics within diagnostic classifications. Objective: In the current study, we examined unique relations of resting-state functional connectivity (RSFC) with Ud and GPF. Method: RSFC data were collected from a mixed group of adolescents (N = 74) with and without psychiatric...

Data from: Current ecology, not ancestral dispersal patterns, influences menopause symptom severity

Yuping Yang, Megan Arnot & Ruth Mace
All human females who reach midlife experience menopause, however, it is currently unclear why women experience this period of infertility, and why it is accompanied by many unpleasant symptoms. Using primary data from four ethnic groups in China, we test an existing theory that age of menopause and its symptoms are the result of intragenomic conflict between maternally and paternally inherited genes, with the outcome of such conflict predicted to be contingent on the ancestral...

Data from: Near-infrared dual bioluminescence imaging in mouse models of cancer using infraluciferin

James Anderson & Martin Pule
Bioluminescence imaging (BLI) is ubiquitous in scientific research for the sensitive tracking of biological processes in small animal models. However, due to the attenuation of visible light by tissue, and the limited set of near-infrared bioluminescent enzymes, BLI is largely restricted to monitoring single processes in vivo. Here we show, that by combining stabilised colour mutants of firefly luciferase (FLuc) with the luciferin (LH2) analogue infraluciferin (iLH2), near-infrared dual BLI can be achievedin vivo. The...

Data from: Cross-species hybridization and the origin of North African date palms

Jonathan M. Flowers, Khaled M. Hazzouri, Muriel Gros-Balthazard, Ziyi Mo, Konstantina Koutroumpa, Andreas Perrakis, Sylvie Ferrand, Hussam S. M. Khierallah, Dorian Q. Fuller, Frederique Aberlenc, Christini Fournaraki & Michael D. Purugganan
Date palm (Phoenix dactylifera L.) is a major fruit crop of arid regions that were domesticated 7,000 y ago in the Near or Middle East. This species is cultivated widely in the Middle East and North Africa, and previous population genetic studies have shown genetic differentiation between these regions. We investigated the evolutionary history of P. dactylifera and its wild relatives by resequencing the genomes of date palm varieties and five of its closest relatives....

Data from: Coupling of palaeontological and neontological reef coral data improves forecasts of biodiversity responses under global climatic change

Lewis A. Jones, Philip D. Mannion, Alexander Farnsworth, Paul J. Valdes, Sarah-Jane Kelland & Peter A. Allison
Reef corals are currently undergoing climatically-driven poleward range expansions, with some evidence for equatorial range retractions. Predicting their response to future climate scenarios is critical to their conservation, but ecological models are based only on short-term observations. The fossil record provides the only empirical evidence for the long-term response of organisms under perturbed climate states. The palaeontological record from the Last Interglacial (LIG; 125,000 years ago), a time of global warming, suggests that reef corals...

Data from: The Chord-Normalized Expected Species Shared (CNESS)-distance represents a superior measure of species turnover patterns

Yi Zou & Jan Axmacher
1. Measures of β-diversity characterizing the difference in species composition between samples are commonly used in ecological studies. Nonetheless, commonly used dissimilarity measures require high sample completeness, or at least similar sample sizes between samples. In contrast, the Chord-Normalized Expected Species Shared (CNESS) dissimilarity measure calculates the probability of collecting the same set of species in random samples of a standardized size, and hence is not sensitive to completeness or size of compared samples. To...

Wannes Hubau, Simon Lewis, Oliver Phillips, Kofi Kofi Affum-Baffoe, Hans Hans Beeckman, Aida Cuni-Sanchez, Corneille Ewango, Sophie Fauset, Douglas Sheil, Bonaventure Sonké, Martin Sullivan, Terry Sunderland, Sean Thomas, Katharine Abernethy, Stephen Adu-Bredu, Christian Amani, Timothy Baker, Lindsay Banin, Fidèle Baya, Serge Begne, Amy Bennett, Fabrice Benedet, Robert Bitariho & Yannick Bocko
Data and R-code from Hubau W et al. 2020. 'Asynchronous Saturation of the Carbon Sink in African and Amazonian tropical forests'. Nature 579, 80-87. 2020. DOI: 10.1038/s41586-020-2035-0. ABSTRACT: Structurally intact tropical forests sequestered ~50% of global terrestrial carbon uptake over the 1990s and early 2000s, offsetting ~15% of anthropogenic CO2 emissions1-3. Climate-driven vegetation models typically predict that this tropical forest ‘carbon sink’ will continue for decades4,5. However, recent inventories of intact Amazonian forests show declining...

Data from: Defining host–pathogen interactions employing an artificial intelligence workflow

Daniel Fisch, Artur Yakimovich, Barbara Clough, Joseph Wright, Monique Bunyan, Michael Howell, Jason Mercer & Eva Frickel
For image-based infection biology, accurate unbiased quantification of host–pathogen interactions is essential, yet often performed manually or using limited enumeration employing simple image analysis algorithms based on image segmentation. Host protein recruitment to pathogens is often refractory to accurate automated assessment due to its heterogeneous nature. An intuitive intelligent image analysis program to assess host protein recruitment within general cellular pathogen defense is lacking. We present HRMAn (Host Response to Microbe Analysis), an open-source image...

Data from: The impact of bilateral ongoing activity on evoked responses in mouse cortex

Daisuke Shimaoka, Nicholas A Steinmetz, Kenneth D Harris & Matteo Carandini
In the absence of external stimuli or overt behavior, the activity of the left and right cortical hemispheres shows fluctuations that are largely bilateral. Here we show that these fluctuations are largely responsible for the variability observed in cortical responses to sensory stimuli. Using widefield imaging of voltage and calcium signals, we measured activity in the cortex of mice performing a visual detection task. Bilateral fluctuations invested all areas, particularly those closest to the midline....

Data from: Terrestrial mammalian wildlife responses to Unmanned Aerial Systems approaches

Emily Bennitt, Hattie L.A. Bartlam-Brooks, Tatjana Y. Hubel & Alan M. Wilson
Unmanned Aerial Systems (UAS) are increasingly being used recreationally, commercially and for wildlife research, but very few studies have quantified terrestrial mammalian reactions to UAS approaches. We used two Vertical Take-off and Landing (VTOL) UAS to approach seven herbivore species in the Moremi Game Reserve, Botswana, after securing the relevant permissions. We recorded responses to 103 vertical and 120 horizontal approaches, the latter from three altitudes above ground level (AGL). We ran mixed logistic regressions...

Data from: Limits to environmental masking of genetic quality in sexual signals

James Malcolm Howie, Harry Alexander Cordeaux Dawson, Andrew Pomiankowski & Kevin Fowler
There is considerable debate over the value of male sexual ornaments as signals of genetic quality. Studies alternately report that environmental variation enhances or diminishes the genetic signal, or leads to crossover where genotypes perform well in one environment but poorly in another. A unified understanding is lacking. We conduct a novel experimental test examining the dual effects of distinct categories of genetic (inbred versus crossed parental lines) and environmental quality (low, through high to...

The impact of genetic adaptation on chimpanzee subspecies differentiation

Joshua Schmidt, Sergi Castellano, Marc De Manuel, Aida Andrés & Tomas Marques-Bonet
Chimpanzees, humans’ closest relatives, are in danger of extinction. Aside from direct human impacts such as hunting and habitat destruction, a key threat is transmissible disease. As humans continue to encroach upon their habitats, which shrink in size and grow in density, the risk of inter-population and cross-species viral transmission increases, a point dramatically made in the reverse with the global HIV/AIDS pandemic. Inhabiting central Africa, the four subspecies of chimpanzees differ in demographic history...

Climate drives community-wide divergence within species over a limited spatial scale: evidence from an oceanic island

Antonia Salces-Castellano, Jairo Patiño, Nadir Alvarez, Carmelo Andújar, Paula Arribas, Juan J. Braojos-Ruiz, Marcelino Del Arco-Aguilar, Víctor García-Olivares, Dirk Karger, Heriberto López, Ioanna Manolopoulou, Pedro Oromí, Antonio J. Pérez-Delgado, William W. Peterman, Kenneth F. Rijsdijk & Brent C. Emerson
Geographic isolation substantially contributes to species endemism on oceanic islands when speciation involves the colonisation of a new island. However, less is understood about the drivers of speciation within islands. What is lacking is a general understanding of the geographic scale of gene flow limitation within islands, and thus the geographic scale and drivers of geographical speciation within insular contexts. Using a community of beetle species, we show that when dispersal ability and climate tolerance...

Intergroup aggression in meerkats

Mark Dyble, Thomas Houslay, Marta Manser & Tim Clutton-Brock
Violent conflicts between groups have been observed among many species of group living mammals and can have important fitness consequences, with individuals being injured or killed and with losing groups surrendering territory. Here, we explore between-group conflict among meerkats (Suricata suricatta), a highly social and cooperatively breeding mongoose. We show that interactions between meerkat groups are frequently 18 aggressive and sometimes escalate to fighting and lethal violence and that these interactions have consequences for group...

Data from: Natural history of limb girdle muscular dystrophy R9 over 6 years: searching for trial endpoints

Alexander P. Murphy, Jasper Morrow, Julia R. Dahlqvist, Tanya Stojkovic, Tracey A. Willis, Christopher D. J. Sinclair, Stephen Wastling, Tarek Yousry, Michael S. Hanna, Meredith K. James, Anna Mayhew, Michelle Eagle, Laurence E. Lee, Jean-Yves Hogrel, Pierre G. Carlier, John S. Thornton, John Vissing, Kieren G. Hollingsworth & Volker Straub
Objective: Limb girdle muscular dystrophy type R9 (LGMD R9) is an autosomal recessive muscle disease for which there is currently no causative treatment. The development of putative therapies requires sensitive outcome measures for clinical trials in this slowly progressing condition. This study extends functional assessments and MRI muscle fat fraction measurements in an LGMD R9 cohort across 6 years. Methods: Twenty‐three participants with LGMD R9, previously assessed over a 1‐year period, were re‐enrolled at 6...

Data from: Is it possible to reconstruct an accurate cell lineage using CRISPR recorders?

Irepan Salvador-Martínez, Marco Grillo, Michalis Averof & Maximilian J. Telford
Cell lineages provide the framework for understanding how multicellular organisms are built and how cell fates are decided during development. Describing cell lineages in most organisms is challenging, given the number of cells involved; even a fruit fly larva has ~50,000 cells and a small mammal has more than 1 billion cells. Recently, the idea of using CRISPR to induce mutations during development as heritable markers for lineage reconstruction has been proposed and trialled by...

Data from: Early consequences of allopolyploidy alter floral evolution in Nicotiana (Solanaceae)

Elizabeth W. McCarthy, Jacob B. Landis, Amelda Kurti, Amber J. Lawhorn, Mark W. Chase, Sandra Knapp, Steven C. Le Comber, Andrew R. Leitch & Amy Litt
Background: Polyploidy has played a major role in angiosperm evolution. Previous studies have examined polyploid phenotypes in comparison to their extant progenitors, but not in context of predicted progenitor phenotypes at allopolyploid origin. In addition, differences in the trends of polyploid versus diploid evolution have not been investigated. We use ancestral character-state reconstructions to estimate progenitor phenotype at allopolyploid origin to determine patterns of polyploid evolution leading to morphology of the extant species. We also...

Acceptability to patients of screening disposable transnasal endoscopy: qualitative interview analysis

John McGoran, Andrea Bennett, Joanne Cooper, John De Caestecker, Laurence Lovat, Indra Neil Guha, Krish Ragunath & Sarmed Sami
Objectives Screening in selected high risk populations for Barrett’s oesophagus (BO) and oesophageal varices (OVs) has been proposed, but there are obstacles with conventional oesophagogastroduodenoscopy (C-OGD), including patient acceptability. Portable and disposable office-based transnasal endoscopy (TNE) is a feasible and accurate alternative to C-OGD that may have use in primary and secondary care. This article outlines a qualitative analysis of patient experiences of TNE and C-OGD in order to gain an insight into an acceptable...
