High heart rates in hunting porpoises

Birgitte McDonald, Siri Elmegaard, Mark Johnson, Danuta Wisniewska, Laia Rojano-Donate, Anders Galatius, Ursula Siebert, Jonas Teilmann & Peter Madsen
The impressive breath-hold capabilities of marine mammals are facilitated by both enhanced O2 stores and reductions in the rate of O2 consumption via peripheral vasoconstriction and bradycardia, coined the dive response. Many studies have focused on the extreme role of the dive response in maximizing dive duration in marine mammals, but few have addressed how these adjustments may compromise the capability to hunt, digest and thermoregulate during routine dives. Here we use DTAGs which record...

Data from: Haplotype associated RNA expression (HARE) improves prediction of complex traits in maize

Anju Giri, Merritt Burch, Edward Buckler & Guillaume Ramstein
Genomic prediction typically relies on associations between single-site polymorphisms and traits of interest. This representation of genomic variability has been successful for prediction within populations. However, it usually cannot capture the complex effects due to combination of alleles in haplotypes. Therefore, accuracy across populations has usually been low. Here we present a novel and cost-effective method for imputing cis haplotype associated RNA expression (HARE, RNA expression of genes by haplotype), studied their transferability across tissues,...

Block-Wise Variable Selection for Clustering Via Latent States of Mixture Models

Beomseok Seo, Lin Lin & Jia Li
Mixture modeling is a major paradigm for clustering in statistics. In this article, we develop a new block-wise variable selection method for clustering by exploiting the latent states of the hidden Markov model on variable blocks or the Gaussian mixture model. The variable blocks are formed by depth-first-search on a dendrogram created based on the mutual information between any pair of variables. It is demonstrated that the latent states of the variable blocks together with...

This dataset includes hand pollination, honey bee pollination and pollen germination experiments described in the article "Pollination and plant reproductive success of two ploidy levels in red clover (Trifolium pratense L.)", published in Frontiers in Plant Science (DOI: 10.3389/fpls.2021.720069). In a series of hand pollination experiments, the influence of visitation rate (10, 20, 40, 80 pollinated florets per flower head) on the seed number per pollinated floret and seed number per flower head were investigated,...

The R package enerscape: A general energy landscape framework for terrestrial movement ecology

Emilio Berti, Marco Davoli, Robert Buitenwerf, Alexander Dyer, Oskar Hansen, Myriam Hirt, Jens-Christian Svenning, Jördis Terlau, Ulrich Brose & Fritz Vollrath
Ecological processes and biodiversity patterns are strongly affected by how animals move through the landscape. However, it remains challenging to predict animal movement and space use. Here we present our new R package enerscape to quantify and predict animal movement in real landscapes based on energy expenditure. Enerscape integrates a general locomotory model for terrestrial animals with GIS tools in order to map energy costs of movement in a given environment, resulting in energy landscapes...

Capturing single-copy nuclear genes, organellar genomes, and nuclear ribosomal DNA from deep genome skimming data for plant phylogenetics: A case study in Vitaceae

Bin-Bin Liu, Zhi-Yao Ma, Chen Ren, Richard Hodel, Miao Sun, Xiu-Qun Liu, Guang-Ning Liu, De-Yuan Hong, Elizabeth Zimmer & Jun Wen
With the decreasing cost and availability of many newly developed bioinformatics pipelines, next-generation sequencing (NGS) has revolutionized plant systematics in recent years. Genome skimming has been widely used to obtain high-copy fractions of the genomes, including plastomes, mitochondrial DNA (mtDNA), and nuclear ribosomal DNA (nrDNA). In this study, through simulations, we evaluated the optimal (minimum) sequencing depth and performance for recovering single-copy nuclear genes (SCNs) from genome skimming data, by subsampling genome resequencing data and...

Deer-vehicle collisions in Denmark

Martin Mayer, Jacob Coleman Nielsen, Morten Elmeros & Peter Sunde
Vehicles collide with hundreds of thousands of deer on European roads each year. This leads to animal deaths and suffering, economic damage and risks for human safety, making the reduction of road mortality a major field in conservation biology. In order to successfully reduce roadkill, we need improved knowledge regarding spatio-temporal patterns of deer-vehicle collisions (DVCs) on a landscape scale. Here, we analyzed >85,000 DVCs collected over 17 years in Denmark to investigate changes in...

Pleistocene climatic fluctuations promoted alternative evolutionary histories in Phytelephas aequatorialis, an endemic palm from western Ecuador

Sebastián Escobar, Andrew J Helmstetter, Scott Jarvie, Rommel Montúfar, Henrik Balslev & Thomas LP Couvreur
Aim: Pleistocene (2.58 Ma – 11.7 ka) climatic fluctuations have shaped intraspecific genetic patterns worldwide; however, their manifestation in many regions remains unknown. In order to determine the impact of Pleistocene climatic fluctuations on the tropical rain forests of western Ecuador, we explored the evolutionary history of the endemic palm Phytelephas aequatorialis. Location: Western Ecuador, northwestern South America. Taxon: Phytelephas aequatorialis (Arecaceae). Methods: 176 nuclear genes were sequenced in 91 individuals for phylogenomic and population...

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...

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...

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...

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)...

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 &...
