Data from: Molecular and quantitative signatures of biparental inbreeding depression in the self-incompatible tree species Prunus avium

Céline Jolivet, Martin Rogge & Bernd Degen
Genetic diversity strongly influences populations’ adaptability to changing environments and therefore survival. Sustainable forest management practices have multiple roles including conservation of genetic resources and timber production. In this study, we aimed at better understanding the variation in genetic diversity among adult and offspring individuals, and the effects of mating system on offspring survival and growth in wild cherry, Prunus avium. We analysed adult trees and open pollinated seed-families from three stands in Germany at...

Data from: Introduced bees (Osmia cornifrons) collect pollen from both coevolved and novel host-plant species within their family-level phylogenetic preferences

Anthony Vaudo, David Biddinger, Wiebke Sickel, Alexander Keller & Margarita M Lopez-Uribe
Studying the pollen preferences of introduced bees allows us to investigate how species utilize host-plants when establishing in new environments. Osmia cornifrons is a solitary bee introduced into North America from East-Asia for pollination of crops in the Rosaceae. We investigated whether O. cornifrons 1) more frequently collected pollen from host-plant species they coevolved with from their geographic origin, or 2) prefer hosts-plant species of specific plant taxa independent of origin. To address this question,...

The FloRes Database: A floral resources trait database for pollinator habitat-assessment generated by a multistep workflow

Franziska Baden-Böhm, Mario App & Jan Thiele
Background The decline of pollinating insects in agricultural landscapes proceeds due to intensive land use and the associated loss of habitat and food sources. The feeding of those insects depends on the spatial and temporal distribution of nectar and pollen as food resources. Hence, to protect insect biodiversity a spatio-temporal assessment of food quantity of their habitats is necessary. Therefore, sufficient data on traits of floral resources are required. New information Because floral resources’ traits...

Data from: Behavioural and fitness effects of translocation to a novel environment: whole-lake experiments in two aquatic top predators

Christopher Monk, Bernard Chéret, Philipp Czapla, Daniel Hühn, Thomas Klefoth, Erik Eschbach, Robert Hagemann & Robert Arlinghaus
Translocation into a novel environment through common fisheries-management practices, such as fish stocking, provides opportunities to study behavioural and fitness impacts of translocations at realistic ecological scales. The process of stocking, as well as the unfamiliarity with novel ecological conditions and the interactions with resident fish may affect translocated individuals, leading to alterations of behaviours and causing fitness impacts. Our objectives were to investigate how aquatic top-predators behaviourally establish themselves and compete with resident individuals...

Species richness in North Atlantic fish: process concealed by pattern

Henrik Gislason, Jeremy Collie, Brian R. MacKenzie, Anders Nielsen, Maria De Fatima Borges, Teresa Bottari, Corina Chavez, Andrey V. Dolgov, Jakov Dulčić, Daniel Duplisea, Heino O. Fock, Didier Gascuel, Luís Gil De Sola, Jan Geert Hiddink, Remment Ter Hofstede, Igor Isajlović, Jónas Páll Jonasson, Ole Jørgensen, Kristján Kristinsson, Gudrun Marteinsdottir, Hicham Masski, Sanja Matić-Skoko, Mark R. Payne, Melita Peharda, Jakup Reinert … & Lilja Stefansdottir
Aim Previous analyses of marine fish species richness based on presence-absence data have shown changes with latitude and average species size, but little is known about the underlying processes. To elucidate these processes we use metabolic, neutral, and descriptive statistical models to analyse how richness responds to maximum species length, fish abundance, temperature, primary production, depth, latitude, and longitude, while accounting for differences in species catchability, sampling effort, and mesh size. Data Results from 53,382...

Functional groups of wild bees respond differently to faba bean (Vicia faba L.) cultivation at landscape scale

Nicole Beyer, Doreen Gabriel, Felix Kirsch, Katharina Schulz-Kesting, Jens Dauber & Catrin Westphal
1. Concerns about insect declines are growing and the provisioning of ecosystem services like pollination may be threatened. To safeguard biodiversity, greening measures were introduced within the reform of the EU’s Common Agricultural Policy. One measure commonly applied by farmers is the cultivation of nitrogen fixing crops. Although underlying studies are largely missing, this measure is criticized as providing no significant biodiversity benefit. 2. Using a landscape-scale approach, we selected 30 paired study landscapes (1km...

Flying insect biomass is negatively associated with urban cover in surrounding landscapes

Cecilie Svenningsen, Diana Bowler, Susanne Hecker, Jesper Bladt, Volker Grescho, Nicole Van Dam, Jens Dauber, David Eichenberg, Rasmus Ejrnæs, Camilla Fløjgaard, Mark Frenzel, Tobias Frøslev, Anders Hansen, Jacob Heilmann-Clausen, Yuanyuan Huang, Jonas Larsen, Juliana Menger, Nur Liyana Nayan, Lene Pedersen, Anett Richter, Robert Dunn, Anders Tøttrup & Aletta Bonn
Aim In this study, we assessed the importance of local to landscape-scale effects of land cover and land use on flying insect biomass. Our main prediction was that insect biomass would be lower within more intensely used land, especially in urban areas and farmland. Location Denmark and parts of Germany. Methods We used rooftop-mounted car nets in a citizen science project (‘InsectMobile’) to allow for large-scale geographic sampling of flying insects. Citizen scientists sampled insects...

Data from: Gene flow by larval dispersal in the Antarctic notothenioid fish Gobionotothen gibberifrons

Michael Matschiner, Reinhold Hanel & Walter Salzburger
The diversification of the teleost suborder Notothenioidei (Perciformes) in Antarctic waters provides one of the most striking examples of a marine adaptive radiation. Along with a number of adaptations to the cold environment, such as the evolution of antifreeze glycoproteins, notothenioids diversified into eight families and at least 130 species. Here, we investigate the genetic population structure of the humped rockcod (Gobionotothen gibberifrons), a benthic notothenioid fish. Six populations were sampled at different locations around...

Data from: All roads lead to home: panmixia of European eel in the Sargasso Sea

Thomas D Als, Michael M Hansen, Gregory E Maes, Martin Castonguay, Lasse Riemann, Kim Aarestrup, Peter Munk, Henrik Sparholt, Reinhold Hanel & Louis Bernatchez
European eels (Anguilla anguilla) spawn in the remote Sargasso Sea in partial sympatry with American eels (Anguilla rostrata), and juveniles are transported more than 5,000 kilometres back to the European and North African coasts. The two species have been regarded as classic textbook examples of panmixia, each comprising a single, randomly mating population. However, several recent studies based on continental samples have found subtle, but significant, genetic differentiation, interpreted as geographical or temporal heterogeneity between...

Small‐scale genetic structure and mating patterns in an extensive sessile oak forest (Quercus petraea (Matt.) Liebl.)

Pascal Eusemann & Heike Liesebach
Oaks (Quercus) are major components of temperate forest ecosystems in the Northern Hemisphere where they form intermediate or climax communities. Sessile oak (Quercus petraea) forests represent the climax vegetation in eastern Germany and western Poland. Here, sessile oak forms pure stands or occurs intermixed with Scots Pine (Pinus sylvestris). A large body of research is available on gene flow, reproduction dynamics, and genetic structure in fragmented landscapes and mixed populations. At the same time, our...

Genotype data of 1970 Pedunculate oak trees (Quercus robur L.) in 13 European countries at 381 gene loci covering the nuclear and organelle genome

Bernd Degen, Yulai Yanbaev, Malte Mader, Ruslan Ianbaev, Svetlana Bakhtina, Hilke Schröder & Céline Blanc-Joliver
The data set is the result of genetic inventory on 1970 Pedunculate oak trees from 197 locations in Europe. The samples are from the countries: Belarus, Bosnia, Bulgaria, Croatia, Finland, France, Germany, Hungary, Italy, Latvia, Poland, Russia and Ukraine. At each location ten individual trees were collected. The data set includes the location ID and geographic coordinates of each sampled tree (longitude and latitude in decimal degrees) and the genotype data. All samples were screened...
