Pollen-chemistry variations along elevation gradients and their implications for a proxy for UV-B radiation in the plant-fossil record

Alistair Seddon, Daniela Festi, Mayke Nieuwkerk, Ragnhild Gya, Børge Hamre, Linn Cecilie Krüger, Silje Östman & T. Matthew Robson
1. Research indicates that the phenolic compounds (e.g. para-coumaric acid) found within pollen grains may be useful as a proxy to reconstruct the UV-B radiation received at the Earth’s surface in the geological past. However, application of this method to the plant-fossil record currently relies on a series of untested assumptions surrounding the ecological factors driving the response of pollen grains in the contemporary environment. 2. Here, we investigate the relationship of Pinus spp. pollen...

Data underlying RSOS-210474: Mitochondrial DNA sequencing of a wet-collection syntype demonstrates the importance of type material as genetic resource for Lantern Shark taxonomy (Chondrichthyes: Etmopteridae)

Nicolas Straube
After initial detection of target archival DNA of a 116 year old syntype specimen of the Smooth Lanternshark, Etmopterus pusillus in a single stranded DNA library, we shotgun-sequenced additional 9 million reads from this same DNA library. Sequencing reads were used for extracting mitochondrial sequence information for analyses of mitochondrial DNA characteristics and reconstruction of the mitochondrial genome. The archival DNA is highly fragmented. A total of 4,599 mitochondrial reads were available for the genome...

A forest pool as a habitat island for mites in a limestone forest in Southern Norway

Anna Seniczak, Stanislaw Seniczak, Radomir Graczyk, Sławomir Kaczmarek, Bjarte H. Jordal, Jarosław Kowalski, Per Djursvoll, Steffen Roth & Thomas Bolger
Forest water bodies, e.g., pools, constitute ‘environmental islands’ within forests, with specific flora and fauna thus contributing considerably to the landscape biodiversity. The mite communities of Oribatida and Mesostigmata in two distinctive microhabitats, water-soaked Sphagnum mosses at the edge of a pool and other mosses growing on the medium-wet forest floor nearby, were compared in a limestone forest in Southern Norway. In total, 16,189 specimens of Oribatida representing 98 species, and 499 specimens of Mesostigmata,...

Analysis of paralogs in target enrichment data pinpoints multiple ancient polyploidy events in Alchemilla s.l. (Rosaceae)

Diego F. Morales-Briones, Berit Gehrke, Chien-Hsun Huang, Aaron Liston, Hong Ma, Hannah Marx, David Tank & Ya Yang
Target enrichment is becoming increasingly popular for phylogenomic studies. Although baits for enrichment are typically designed to target single-copy genes, paralogs are often recovered with increased sequencing depth, sometimes from a significant proportion of loci, especially in groups experiencing whole-genome duplication (WGD) events. Common approaches for processing paralogs in target enrichment data sets include random selection, manual pruning, and mainly, the removal of entire genes that show any evidence of paralogy. These approaches are prone...

Global distribution and evolutionary transitions of angiosperm sexual systems

Yunyun Wang, Ao Luo, Tong Lyu, Dimitar Dimitrov, Xiaoting Xu, Robert Freckleton, Yaoqi Li, Xiangyan Su, Yichao Li, Yunpeng Liu, Denis Sandanov, Qingjun Li, Zhanqing Hao, Shuguang Liu & Zhiheng Wang
Angiosperm sexual systems are fundamental to the evolution and distribution of plant diversity, yet spatiotemporal patterns in angiosperm sexual systems and their drivers remain poorly known. Using data on sexual systems and distributions of 68453 angiosperm species, we present the first global maps of sexual system frequencies and evaluate sexual system evolution during the Cenozoic. Frequencies of dioecy and monoecy increase with latitude, while hermaphrodites are more frequent in warm and arid regions. Transitions to...

Predator-prey overlap in three dimensions: cod benefit from capelin coming near the seafloor

Johanna Fall, Edda Johannesen, Göran Englund, Geir Odd Johansen & Øyvind Fiksen
Spatial overlap between predator and prey is a prerequisite for predation, but the degree of overlap is not necessarily proportional to prey consumption. This is because many of the behavioural processes that precede ingestion are non-linear and depend on local prey densities. In aquatic environments, predators and prey distribute not only across a surface, but also vertically in the water column, adding another dimension to the interaction. Integrating and simplifying behavioural processes across space and...

Acoustic and fluorescence data from: A marine zooplankton community vertically structured by light across diel to interannual timescales

Laura Hobbs, Neil Banas, Jonathan Cohen, Finlo Cottier, Jørgen Berge & Øystein Varpe
The predation risk of many aquatic taxa is dominated by visually searching predators, commonly a function of ambient light. Several studies propose that changes in visual predation will become a major climate-change impact on polar marine ecosystems. The high Arctic experiences extreme seasonality in the light environment, from 24-h light to 24-h darkness, and therefore provides a natural laboratory for studying light and predation risk over diel to seasonal timescales. Here, we show that zooplankton...

Global dryland vegetation memory

Erik Kusch, Alistair W. Seddon & Richard Davy
1. Vegetation memory describes the effect of antecedent environmental and ecological conditions on the present ecosystem state and has been proposed as an important proxy for vegetation resilience. In particular, strong vegetation-memory effects have been identified in dryland regions, but the factors underlying the spatial patterns of vegetation memory remain unknown. 2. We aim to map the components and drivers of vegetation memory in dryland regions using state-of-the-art climate-reanalysis data and refined approaches to identify...

Type of broadleaf forest matters most for ptyctimous mite communities (Acari, Oribatida) in Norway

Anna Seniczak, Wojciech Niedbała, J. Carlos Iturrondobeitia, Stanisław Seniczak, Steffen Roth & Bjarte H. Jordal
We studied ptyctimous moss mites, which are characteristic of forest habitats, in Norwegian broadleaf forests considered as biodiversity hotspot areas in Fennoscandia. The study aimed to evaluate the effect of different factors (regional locality, annual precipitation, mean annual temperature, forest type, forest wetness and microhabitat) on the ptyctimous mites and on discovering their richness in broadleaf forests. Samples were collected from nine broadleaf forests in western, southern and eastern Norway, in different climatic conditions, six...

Fungal DNA was extracted before sequencing of the internal transcribed spacer 1 (ITS1) region of the fungal ribosomal RNA gene cluster. Taxonomic barplots...

High diversity of mites (Acari: Oribatida, Mesostig-mata) supports the high conservation value of a broadleaf forest in Eastern Norway

Anna Seniczak, Stanisław Seniczak, Josef Starý, Sławomir Kaczmarek, Bjarte Jordal, Jarosław Kowalski, Steffen Roth, Per Djursvoll & Thomas Bolger
Broadleaf forests are critical habitats for biodiversity and this biodiversity is in turn essential for their proper functioning. Mites (Acari) are a numerous and functionally essential component of these forests. We report the diversity of two important groups, Oribatida and Mesostigmata, in a broadleaf forest in Eastern Norway which is considered to be a biodiversity hotspot. Eighteen samples, each 500 cm3, were collected from diverse microhabitats (moss on ground, lichens on tree twigs lying on...

Data from: Participatory mapping reveals biocultural and nature values in the shared landscape of a Nordic UNESCO Biosphere Reserve

Jarrod Cusens, Alicia Donnellan Barraclough & Inger Måren
1. Making the right decisions for sustainable development requires sound knowledge of the values and spatial distribution of the services co-produced by ecosystems and people. UNESCO’s Man and the Biosphere programme and associated Biosphere Reserves (BRs) are key learning sites or model regions for sustainable development providing key entry points for transdisciplinary work on sustainable development. However, there is limited research exploring spatial distribution of socio-cultural Ecosystem Service (ES) values in BRs and how those...

The averaging time was 25 minutes. The timestamp indicates the beginning of the averaging period. The measurement system was set up at 2.15m height and measured isotope fluxes above the snow surface from 25.05.2019-29.07.2019 at the EastGRIP site in the accumulation zone of the Greenland Ice Sheet. The data is...

Phytogeographic history of the Tea family inferred through high-resolution phylogeny and fossils

Yujing Yan, Charles Davis, Dimitar Dimitrov, Zhiheng Wang, Carsten Rahbek & Michael Borregaard
The tea family (Theaceae) has a highly unusual amphi-Pacific disjunct distribution: most extant species in the family are restricted to subtropical evergreen broadleaf forests in East Asia, while a handful of species occur exclusively in the subtropical and tropical Americas. Here we used an approach that integrates the rich fossil evidence of this group with phylogenies in biogeographic analysis to study the processes behind this distribution pattern. We first combined genome-skimming sequencing with existing molecular...

Considering sampling bias in close-kin mark-recapture (CKMR) abundance estimates of Atlantic salmon

Sebastian Wacker, Hans Skaug, Torbjørn Forseth, Øyvind Solem, Eva Ulvan, Peder Fiske & Sten Karlsson
Genetic methods for the estimation of population size can be powerful alternatives to conventional methods. Close-kin mark-recapture (CKMR) is based on the principles of conventional mark-recapture, but instead of being physically marked, individuals are marked through their close kin. The aim of this study was to evaluate the potential of CKMR for the estimation of spawner abundance in Atlantic salmon and how age, sex, spatial, and temporal sampling bias may affect CKMR estimates. Spawner abundance...
