Simulated ice thickness, supraglacial debris thickness and subglacial topography for Khumbu Glacier, Nepal, using the iSOSIA ice-flow model - VERSION 2.0

Ann Rowan & David Egholm
Simulated ice thickness (ice, metres, 100 m grid spacing) and supraglacial debris thickness (debris, metres, 100 m grid spacing) for Khumbu Glacier, Nepal, produced using the iSOSIA ice-flow model presented in Rowan et al. (2021; Journal of Geophysical Research-Earth Surface). The model domains used for the entire glacier and active glacier simulations (metres above sea level, 100 m grid spacing), and the present-day ice thickness estimate (metres, 30 m grid spacing) used to create the...

GPS data of little owls

Martin Mayer, Martin Šálek, Anthony Fox, Frej Juhl Lindhøj, Lars Bo Jacobsen & Peter Sunde
Advances in bio-logging technology for wildlife monitoring have expanded our ability to study space use and behavior of many animal species at increasingly detailed scales. However, such data can be challenging to analyze due to autocorrelation of GPS positions. As a case study, we investigated spatiotemporal movements and habitat selection in the little owl (Athene noctua), a bird species that is declining in central Europe and verges on extinction in Denmark. We equipped 6 Danish...

Species packing and the latitudinal gradient in local beta-diversity

Ke Cao, Richard Condit, Xiangcheng Mi, Lei Chen, Wubing Xu, David F. R. P. Burslem, Chunrong Cai, Min Cao, Li-Wan Chang, Chengjin Chu, Hu Du, Sisira Ediriweera, C. S. V. Gunatilleke, I. U. A. N. Gunatilleke, Zhanqing Hao, Jinbo Li, Guangze Jin, Buhang Li, Yankun Liu, Yide Li, Michael J. O'Brien, Xiujuan Qiao, Hongwei Ni, Guochun Shen, Xihua Wang … & Jens-Christian Svenning
The decline in species richness at higher latitudes is among the most fundamental patterns in ecology. Whether changes in species composition across space (beta-diversity) contribute to this gradient of overall local species richness (gamma diversity) remains hotly debated. Previous studies that failed to resolve the issue suffered from a well-known tendency for small samples in areas with high gamma-diversity to have inflated measures of beta-diversity. We provide here a novel analytical test, using beta-diversity metrics...

Population ecology and dynamics of a remnant natural population of European yew (Taxus baccata) in a lowland temperate forest – implications for use in reforestation

Ditte Arp Jensen & Jens-Christian Svenning
There is increasing focus on reforestation, but the efforts still often include limited subsets of species despite evidence that tree diversity promote biodiversity and ecological resilience. In addition to these benefits, greater inclusion of rare native species in reforestation efforts would also help conserve these species in an uncertain future. Here, we investigate the population ecology and dynamics of the only remaining historical population of the shade-adapted under- and mid-story tree European yew (Taxus baccata)...

Seasonal turnover in community composition of stream-associated macroinvertebrates inferred from freshwater environmental DNA metabarcoding

Mads Reinholdt Jensen, Eva Egelyng Sigsgaard, Sune Agersnap, Jes Jessen Rasmussen, Annette Baattrup-Pedersen, Peter Wiberg-Larsen & Philip Francis Thomsen
Macroinvertebrate communities are crucial for biodiversity monitoring and assessment of ecological status in stream ecosystems. However, traditional monitoring approaches require intensive sampling and rely on invasive morphological identifications that are time consuming and dependent on taxonomic expertise. Importantly, sampling is often only carried out once in a year, namely during late winter – spring, where most indicator taxa have larval stages in the streams. Hence, species with divergent phenology might not be detected. Here, we...

Decreased precipitation in the late growing season weakens an ecosystem carbon sink in a semiarid grassland

Zhongling Yang, Yueyue Wei, Guangya Fu, Rui Xiao, Ji Chen, Yaojun Zhang, Dong Wang & Junyong Li
1. Net ecosystem gas exchange (NEE), a balance between gross ecosystem primary productivity (GPP) and ecosystem respiration (ER), is an important indicator of terrestrial ecosystem CO2 sink or source. Increasing frequency of droughts during different periods of the growing season may affect terrestrial ecosystem carbon balance. However, detecting how drought timing controls ecosystem carbon processes is insufficiently explored because it is a challenge to accurately monitor and forecast drought dynamics. 2. In a five-year (2015-2019)...

An ecoregion-based approach to restoring the world’s intact large mammal assemblages

Carly Vynne, Joe Gosling, Calum Maney, Eric Dinerstein, Andy T. L. Lee, Neil Burgess, Néstor Fernández, Sanjiv Fernando, Harshini Jhala, Yadvendradev Jhala, Reed Noss, Michael Proctor, Jan Schipper, José F. González-Maya, Anup Joshi, David Olson, William J. Ripple & Jens-Christian Svenning
Assemblages of large mammal species play a disproportionate role in the structure and composition of natural habitats. Loss of these assemblages destabilizes natural systems, while their recovery can restore ecological integrity. Here we take an ecoregion-based approach to identify landscapes that retain their historically present large mammal assemblages, and map ecoregions where reintroduction of 1–3 species could restore intact assemblages. Intact mammal assemblages occur across more than one-third of the 730 terrestrial ecoregions where large...

Pollinator visits to six plant species in an oil palm landscape

Candice C. Power, Anders Nielsen & Douglas Sheil
Pollination sustains biodiversity and food security, but pollinators are threatened by habitat degradation, fragmentation and loss. Here we aimed to assess how remaining forests influence bee visits to flowers in an oil palm dominated landscape in Borneo, Indonesia. To do this, we observed pollinator visits to six plant species: four crops (Capsicum frutescens L. “chili”; Citrullus lanatus (Thunb.) Matsum. & Nakai “watermelon”; Solanum lycopersicum L. “tomato”; and Solanum melongena L. “eggplant”); one native plant Melastoma...

Large herbivore biomass in protected areas

Camilla Fløjgaard, Pil Birkefeldt Møller Pedersen, Christopher Sandom, Jens-Christian Svenning & Rasmus Ejrnæs
Large herbivores provide key ecosystem processes, but have experienced massive historical losses and are under intense pressure, leaving current ecosystems with dramatically simplified faunas relative to the long-term evolutionary norm. Hampered by a shifting baseline, natural levels of large-herbivore biomass are poorly understood and seldom targeted. Here, we present a collation of large-herbivore biomass data from published sources as well as personal communication. The data includes continent, ecosystem name, latitude, longitude, large herbivore biomass in...

Data and code from: Accounting for species interactions is necessary for predicting how arctic arthropod communities respond to climate change

Nerea Abrego, Tomas Roslin, Tea Huotari, Yinqiu Ji, Niels Martin Schmid, Jiaxin Wang, Douglas W. Yu & Otso Ovaskainen
Species interactions are known to structure ecological communities. Still, the influence of climate change on biodiversity has primarily been evaluated by correlating individual species distributions with local climatic descriptors, then extrapolating into future climate scenarios. We ask whether predictions on arctic arthropod response to climate change can be improved by accounting for species interactions. For this, we use a 14-year-long, weekly time series from Greenland, resolved to the species level by mitogenome mapping. During the...

Data from: Holocene lake phosphorus species and primary producers reflect catchment processes in a small, temperate lake

Anna-Marie Klamt, Sofie P. Poulsen, Bent V. Odgaard, Thomas Hübener, Suzanne McGowan, Henning S. Jensen & Kasper Reitzel
This palaeo data set consists of a Holocene record from a small, temperate lake (Lake Fuglsø, Denmark). It comprises radiocarbon (14C)-dating, pollen, X-ray fluorescence scanning, carbon and nitrogen (contents and stable isotopes), phosphorus (P) pools (from sequential P extraction and 31P nuclear magnetic resonance spectroscopy), pigment, diatom, and plant macrofossil data. Our multi-proxy palaeolimnological study aimed to investigate how natural processes and anthropogenic land-use changes have affected sedimentary P forms and primary producers. We found...

Data for: Parasitoids indicate major climate-induced shifts in Arctic communities

Tuomas Kankaanpää, Eero Vesterinen, Bess Hardwick, Niels Martin Martin Schmidt, Tommi Andersson, Paul Eric Aspholm, Isabel Barrio, Niklas Beckers, Joël Bêty, Tone Birkemoe, Melissa DeSiervo, Katherine Drotos, Dorothee Ehrich, Olivier Gilg, Vladimir Gilg, Nils Hein, Toke Høye, Kristian Jakobsen, Camille Jodouin, Jesse Jorna, Mikhail Kozlov, Jean-Claude Kresse, Don-Jean Leandri-Breton, Nicolas Lecomte, Maia Olsen … & Tomas Roslin
Climatic impacts are especially pronounced in the Arctic, which as a region is warming twice as fast as the rest of the globe. Here, we investigate how mean climatic conditions and rates of climatic change impact parasitoid insect communities in 16 localities across the Arctic. We focus on parasitoids in a wide-spread habitat, Dryas heathlands, and describe parasitoid community composition in terms of larval host use (i.e. parasitoid use of herbivorous Lepidoptera versus pollinating Diptera)...

Data from: Wintering bird communities are tracking climate change faster than breeding communities

Aleksi Lehikoinen, Åke Lindström, Andrea Santangeli, Päivi Sirkiä, Lluis Brotons, Vincent Devictor, Jaanus Elts, Ruud P. B. Fobben, Henning Heldbjerg, Sergi Herrando, Marc Herremans, Marie-Anne R. Hudson, Frederic Jiguet, Alison Johnston, Romain Lorrilliere, Emma-Liina Marjakangas, Nicole L. Michel, Charlotte M. Moshøj, Renno Nellis, Jean-Yves Paquet, Adam C. Smith, Tibor Szep & Chris Van Turnhout
1. Global climate change is driving species’ distributions towards the poles and mountain tops during both non-breeding and breeding seasons, leading to changes in the composition of natural communities. However, the degree of season differences in climate-driven community shifts has not been thoroughly investigated at large spatial scales. 2. We compared the rates of change in the community composition during both winter (non-breeding season) and summer (breeding) and their relation to temperature changes. 3. Based...

Eiders, nutrients and eagles: Bottom-up and top-down population dynamics in a marine bird_dataset

Federico Morelli, Karsten Laursen, Marek Svitok, Yanina Benedetti & Anders Pape Møller
The main objective of this long-term study (1978-2016) was to find the underlying factors behind the declining trends of eider Somateria mollissima in the Baltic/Wadden Sea. Specifically, we aimed at quantifying the bottom-up effect of nutrients, through mussel stocks, on reproduction and abundance of eider, and the top-down effects caused by white-tailed eagle Haliaeetus albicilla predation. Bottom-up effects increase marine primary productivity with subsequent effects on food availability for a major mussel predator. Top-down effects...

Data on infection experiments of cane toads

Martin Mayer, Lia Schlippe Justicia, Richard Shine & Gregory Brown
This dataset contains data from an infection experiment described in the paper: “Mayer, M., Schlippe Justicia, L, Shine, R., & Brown, G. P. (2021). Host defense or parasite cue: Skin secretions mediate interactions between amphibians and their parasites. Ecology Letters, in revision”. Amphibian skin secretions (substances produced by the amphibian plus microbiota) plausibly act as a first line of defense against parasite/pathogen attack, but may also provide chemical cues for pathogens. To clarify the role...

A comprehensive phylogenomic platform for exploring the angiosperm tree of life

William Baker, Paul Bailey, Vanessa Barber, Abigail Barker, Sidonie Bellot, David Bishop, Laura Botigue, Grace Brewer, Tom Carruthers, James Clarkson, Jeffrey Cook, Robyn Cowan, Steven Dodsworth, Niroshini Epitawalage, Elaine Françoso, Berta Gallego, Matthew Johnson, Jan Kim, Kevin Leempoel, Olivier Maurin, Catherine McGinnie, Lisa Pokorny, Shyamali Roy, Malcolm Stone, Eduardo Toledo … & Félix Forest
The tree of life is the fundamental biological roadmap for navigating the evolution and properties of life on Earth, and yet remains largely unknown. Even angiosperms (flowering plants) are fraught with data gaps, despite their critical role in sustaining terrestrial life. Today, high-throughput sequencing promises to significantly deepen our understanding of evolutionary relationships. Here, we describe a comprehensive phylogenomic platform for exploring the angiosperm tree of life, comprising a set of open tools and data...

Hare disturbance GPS data

Martin Mayer, Lars Haugaard & Peter Sunde
Capture and handling of wildlife is an important component of wildlife studies, and hunting can be a central tool for wildlife management. However, human-caused disturbance of animals can cause various negative effects on individuals. Thus, an increased understanding of different disturbances on animals will allow improved mitigation of human stressors for wildlife, and provides the basis for data‐censoring when using information obtained from captured individuals. Here, we investigated the effects of capture and handling, as...

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....

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...

Rewetting does not return drained fen peatlands to their old selves

Juergen Kreyling, Franziska Tanneberger, Florian Jansen, Sebastian Van Der Linden, Camiel Aggenbach, Volker Blüml, John Couwenberg, Willem-Jan Emsens, Hans Joosten, Agatha Klimkowska, Wiktor Kotowski, Lukasz Kozub, Bernd Lennartz, Yvonne Liczner, Haojie Liu, Dierk Michaelis, Claudia Oehmke, Karsten Parakenings, Elisabeth Pleyl, Arne Poyda, Stefanie Raabe, Markus Röhl, Kirsten Rücker, Anett Schneider, Joachim Schrautzer … & Gerald Jurasinski
Peatlands, in particular groundwater-fed fens of the temperate zone, have been drained for agriculture, forestry and peat extraction for a long time and on a large scale. Drainage turns peatlands from a carbon and nutrient sink into a respective source, diminishes water regulation capacity at the landscape scale, causes continuous surface height loss and destroys their typical biodiversity. Over the last decades, drained peatlands have been rewetted for biodiversity restoration and, as it strongly decreases...

Data from: Using singleton densities to detect recent selection in Bos taurus

Matthew Hartfield, Nina Aagaard Poulsen, Bernt Guldbrandtsen & Thomas Bataillon
Many quantitative traits are subject to polygenic selection, where several genomic regions undergo small, simultaneous changes in allele frequency that collectively alter a phenotype. The widespread availability of genome data, along with novel statistical techniques, has made it easier to detect these changes. We apply one such method, the ‘Singleton Density Score’, to the Holstein breed of Bos taurus to detect recent selection (arising up to around 740 years ago). We identify several genes as...

Irreproducibility in searches of scientific literature: a comparative analysis

Gabor Pozsgai, Gabor Lövei, Liette Vasseur, Geoff Gurr, Péter Batáry, Janos Korponai, Nick Littlewood, Jian Liu, Arnold Móra, John Obrycki, Olivia Reynolds, Jenni Stockan, Heather VanVolkenburg, Jie Zhang, Wenwu Zhou & Minsheng You
1. Repeatability is the cornerstone of science and it is particularly important for systematic reviews. However, little is known on how researchers’ choice of database and search platform influence the repeatability of systematic reviews. Here, we aim to unveil how the computer environment and the location where the search was initiated from influence hit results. 2. We present a comparative analysis of time-synchronized searches at different institutional locations in the world, and evaluate the consistency...

Plant community data for European ecoregions

Jose A. Capitan, Sara Cuenda, Alejandro Ordoñez & David Alonso
Patterns in macroecology are related to species occurrence across meaningful spatial and temporal scales. The dataset provided here reports species distribution data (presence-absence) for herbaceous plants across a number of European habitats (ecoregions). Species occurrence is accompanied by the corresponding plant's maximun stem height values. This dataset has been used to unveil patterns of herbaceous plant height clustering in mid-latitude European ecoregions. Presence-absence data for herbaceous plants were drawn from Atlas Florae Europaeae (Jalas &...

The concurrent assessment of agronomic, ecological, and environmental variables enables better choice of agroecological service crop termination management

David Navarro-Miró, José M. Blanco-Moreno, Corrado Ciaccia, Elena Testani, Ileana Iocola, Laura Depalo, Giovanni Burgio, Hanne Lakkenborg Kristensen, Margita Hefner, Kalvi Tamm, Ingrid Bender, Alessandro Persiani, Mariangela Diacono, Francesco Montemurro, Koen Willekens, Hélène Védie, Martina Bavec, Martina Robačer, Donatienne Arlotti, Pauline Deltour, Stefaan De Neve, Mesfin Tsegaye Gebremikael, Lourdes Chamorro, Berta Caballero-López, Alejandro Pérez-Ferrer … & F. Xavier Sans
1. Although organic farming was originally promoted as an alternative farming system to address agronomic, environmental, and ecological issues, its conventionalisation has led to an intensification and specialisation of production. In light of this, several studies have questioned the environmental benefits of organic farming as well as its agronomic viability. Thus, there is a need to improve organic vegetable systems to reduce their environmental impact without affecting their productivity. To tackle this challenge, European farmers...

Echolocation activity of harbour porpoises, Phocoena phocoena, show seasonal artificial reef attraction despite elevated noise levels close to oil and gas platforms

Jonas Teilmann
Harbour porpoises frequently alter their behaviour in response to underwater sound from shipping, seismic surveys, drilling and marine renewables. Less well understood is the response of porpoises to sounds emitted from oil and gas (O&G) platforms during routine operations. The responses are not easily predictable as platforms can act simultaneously and to varying degree as a source of disturbance through noise and attraction through an artificial reef effect with increased prey abundance and diversity. To...
