Geographic variation and temporal trends in ice phenology in Norwegian lakes during a century

Leif Asbjørn Vøllestad, Jan Henning L’Abée-Lund, John E. Brittain, Ånund Kvambekk & Tord Solvang
The physical characteristics of ice formation in water courses are ideal for studying climatic variation in space and time. We used a large set of observations for 9-116 years (1890-2019) of the timing of freeze-up and break-up, and the length of ice-free season for 99 Norwegian lakes to elucidate variation in ice phenology across space and time. The dataset of Norwegian lakes is unusual, covering considerable variation in altitude (4 – 1401 m above sea...

Contrasting demographic histories revealed in two invasive populations of the dry rot fungus Serpula lacrymans

Inger Skrede, Claude Murat, Jaqueline Hess, Sundy Maurice, Jørn Henrik Sønstebø, Annegret Kohler, Dominique Barry-Etienne, Dan Eastwood, Nils Högberg, Francis Martin & Håvard Kauserud
Globalization and international trade have impacted organisms around the world leading to a considerable number of species establishing in new geographic areas. Many organisms have taken advantage of human-made environments, including buildings. One such species is the dry rot fungus Serpula lacrymans, which is the most aggressive wood-decay fungus in indoor environments in temperate regions. Using population genomic analyses of 36 full genome sequenced isolates, we demonstrated that European and Japanese isolates are highly divergent...

Mixed-phase orographic cloud microphysics during StormVEx and IFRACS

Douglas Lowenthal, A. Gannet Hallar, Robert O. David, Ian B. McCubbin, Randolph D. Borys & Gerald G. Mace
Wintertime mixed-phase orographic cloud (MPC) measurements were conducted at the Storm Peak Laboratory (SPL) during the Storm Peak Lab Cloud Property Validation Experiment (StormVEx) and Isotopic Fractionation in Snow (IFRACS) programs in 2011 and 2014, respectively. The data include 92 h of simultaneous measurements of supercooled liquid cloud droplet and ice particle size distributions (PSDs). Average cloud droplet number concentration (CDNC), droplet size (NMD), and liquid water content (LWC) were similar in both years, while...

Data from: Length variation in short tandem repeats affects gene expression in natural populations of Arabidopsis thaliana

William B Reinar, Vilde O Lalun, Trond Reitan, Kjetill S Jakobsen & Melinka A Butenko
The genetic basis for the fine-tuned regulation of gene expression is complex and ultimately influences the phenotype and thus the local adaptation of natural populations. Short tandem repeats (STRs) consisting of repetitive DNA motifs have been shown to regulate gene expression. STRs are variable in length within a population and serve as a heritable, but semi-reversible, reservoir of standing genetic variation. For sessile organisms such as plants, STRs could be of major importance in fine-tuning...

What does it mean to be wild? Assessing anthropogenic environments of nonhuman primate specimens in museum collections

Andrea Eller, Stephanie Canington, Sana Saiyed, Courtney Hoffman, Rita Austin & Sabrina Sholts
Natural history collections are often thought to represent environments in a pristine natural state, free from human intervention – the so-called “wild”. In this study, we aim to assess the level of human influence represented by natural history collections of wild-collected primates over 120 years at the Smithsonian Institution’s National Museum of Natural History (NMNH). Our sample consisted of 875 catarrhine primate specimens in NMNH collections, representing 13 genera collected from 39 countries (1882–2004). Using...

Data from: Validating marine Devonian biogeography: a study in bioregionalization

Elizabeth Dowding, Malte Ebach & Evgeny Mavrodiev
The Devonian record presents an opportunity to test and validate an existing marine bioregionalisation. This study is the first to use comparative biogeography and phylogenetic data to test Devonian bioregionalisation. Proposed in the 1960’s the Old World, Eastern Americas, and Malvinokaffric realms have been the functional standard within marine Devonian Biogeography. Data from 32 published phylogenies of Devonian marine taxa and a database of c.800 occurrences were analysed using phylogenetic software to test for area...

Birds may decorated their nest to exploit a fear of feathers

Tore Slagsvold & Karen L. Wiebe
This dataset contains data from experiments carried out in a woodland area and described in the paper: “T. Slagsvold, and Wiebe, K. L. (2021) "Nest decoration: birds exploit a fear of feathers to guard their nest from usurpation". The experiments investigated a new hypothesis, namely that some cavity nesting birds, like titmice, add feathers on the top of their nest to prevent usurpation by triggering a fear response in their rivals. We presented pied flycatchers...

MetaComNet: A random forest-based framework for making spatial prediction of plant-pollinator interactions

Markus Arne Kjær Sydenham, Zander Venter, Trond Reitan, Claus Rasmussen, Astrid Skrindo, Daniel Skoog, Kaj-Andreas Hanevik, Stein Joar Hegland, Yoko Dupont, Anders Nielsen, Joseph Chipperfield & Graciela Rusch
1. Predicting plant-pollinator interaction networks over space and time will improve our understanding of how environmental change is likely to impact the functioning of ecosystems. Here we propose a framework for producing spatially explicit predictions of the occurrence and number of pairwise plant-pollinator interactions and of the species richness, diversity, and abundance of pollinators visiting flowers. We call the framework ‘MetaComNet’ because it aims to link metacommunity dynamics to the assembly of ecological networks. 2....

Definition of the CIDOC Conceptual Reference Model v7.1.1

Chryssoula Bekiari, George Bruseker, Martin Doerr, Christian-Emi Ore, Stephen Stead & Athanasios Velios
This document is the formal definition of the CIDOC Conceptual Reference Model (“CIDOC CRM”), an event-centric model which facilitates the integration, mediation and interchange of heterogeneous cultural-historical information by providing a semantic representation appropriate to the accurate representation of the interconnection of facts related to past human activities of all kinds, to their material and intellectual context and to cultural heritage objects through time and space. The CRM is the culmination of more than two...

Data and scripts for: Quantitative assessment of observed vs. predicted responses to selection

Christophe Pelabon, Elena Albertsen, Arnaud Le Rouzic, Cyril Firmat, Geir H. Bolstad, W. Scott Armbruster & Thomas Hansen
Although artificial-selection experiments seem well suited to testing our ability to predict evolution, the correspondence between predicted and observed responses is often ambiguous due to the lack of uncertainty estimates. We present equations for assessing prediction error in direct and indirect responses to selection that integrate uncertainty in genetic parameters used for prediction and sampling effects during selection. Using these, we analyzed a selection experiment on floral traits replicated in two taxa of the Dalechampia...

Epidemiology of epilepsy in Nigeria: A community-based study from 3 sites

Musa Mamman Watila, Salisu A. Balarabe, Morenikeji A. Komolafe, Stanley C. Igwe, Michael B. Fawale, Willem M. Otte, Eric Van Diessen, Olaitan Okunoye, Anthony A. Mshelia, Ibrahim Abdullahi, Joseph Musa, Erick W. Hedima, Yakub W. Nyandaiti, Gagandeep Singh, Andrea S. Winkler & Josemir W. Sander
Background: We determined the prevalence, incidence, and risk factors for epilepsy in Nigeria. Methods: We conducted a door-to-door survey to identify cases of epilepsy in three regions. We estimated age-standardized prevalence adjusted for non-response and sensitivity and the one-year retrospective incidence for active epilepsy. To assess potential risk factors, we conducted a case-control study by collecting sociodemographic and risk factor data. We estimated odds ratios (ORs) using logistic regression analysis and corresponding population attributable fractions...

Major population splits coincide with episodes of rapid climate change in a forest-dependent bird

Vera-Maria Warmuth, Malcolm Burgess, Marko Mägi, Toni Laaksonen, Andrea Manica, Andreas Nord, Craig Primmer, Glenn-Peter Sætre, Wolfgang Winkel & Hans Ellegren
Climate change influences population demography by altering patterns of gene flow and reproductive isolation. Direct mutation rates offer the possibility for accurate dating on the within-species level but are currently only available for a handful of vertebrate species. Here, we use the first directly estimated mutation rate in birds to study the evolutionary history of pied flycatchers (Ficedula hypoleuca). Using a combination of demographic inference and environmental niche modelling, we show that all major population...

Composite landscape predictors improve distribution models of ecosystem types

Trond Simensen, Peter Horvath, Julien Vollering, Lars Erikstad, Rune Halvorsen & Anders Bryn
Aim: Distribution modelling is a useful approach to obtain knowledge about the spatial distribution of biodiversity, required for e.g., red list assessments. While distribution modelling methods have been applied mostly to single species, modelling of communities and ecosystems (EDM; ecosystem-level distribution modelling) produces results that are more directly relevant for management and decision-making. Although the choice of predictors is a pivotal part of the modelling process, few studies have compared the suitability of different sets...

Pedro M. Martin-Sanchez, Eva-Lena F. Estensmo, Luis N. Morgado, Sundy Maurice, Ingeborg B. Engh, Inger Skrede & Håvard Kauserud
In the built environment, fungi can cause important deterioration of building materials and adverse health effects for the occupants. Increased knowledge about indoor mycobiomes from different regions of the world, and their main environmental determinants, will enable improved indoor air quality management and identification of health risks. This is the first citizen science study about indoor mycobiomes at a large geographical scale in Europe, including 271 houses from Norway and 807 dust samples from three...

Pervasive admixture and the spread of a large-lipped form in a cichlid fish radiation

Will Sowersby, José Cerca, Bob Wong, Topi Lehtonen, David Chapple, Mariana Leal-Cardin, Marta Barluenga & Mark Ravinet
Adaptive radiations have proven important for understanding the mechanisms and processes underlying biological diversity. The convergence of form and function, as well as admixture and adaptive introgression, are common in adaptive radiations. However, distinguishing between these two scenarios remains a challenge for evolutionary research. The Midas cichlid species complex (Amphilophus spp.) is a prime example of adaptive radiation, with phenotypic diversification occurring at various stages of genetic differentiation. One species, A. labiatus, has large fleshy...

Misreading the Bengal Delta

Camelia Dewan
Perilously close to sea level and vulnerable to floods, erosion, and cyclones, Bangladesh is one of the top recipients of development aid earmarked for climate change adaptation. Yet, to what extent do adaptation projects address local needs and concerns? Combining environmental history and ethnographic fieldwork with development professionals, rural farmers, and landless women, Misreading the Bengal Delta critiques development narratives of Bangladesh as a “climate change victim.” It examines how development actors repackage colonial-era modernizing...

Analyzing disparity and rates of morphological evolution with model-based phylogenetic comparative methods

Thomas F. Hansen, Geir Bolstad & Masahito Tsuboi
Understanding variation in rates of evolution and morphological disparity is a goal of macroevolutionary research. In a phylogenetic comparative methods framework, we present three explicit models for linking the rate of evolution of a trait to the state of another evolving trait. This allows testing hypotheses about causal influences on rates of phenotypic evolution with phylogenetic comparative data. We develop a statistical framework for fitting the models with generalized least-squares regression, and use this to...
