The Politics of Euro-Balkan Police Cooperation in the 2000s

Olga Kantokoski
This article examines the political dynamics of Euro-Balkan police cooperation in the context of recent Balkan history. In the existing scholarship, the process of the ‘externalisation’ of EU-wide law enforcement cooperation outside the Union's geographic frontiers is widely considered to be a ‘functional-instrumental’ response to the menace of organised crime. Scholars believe that the functional rationale has been a primary driver behind the Union's endeavours to extend its governance of internal security to the EU's...

Data from: Reliable wolf-dog hybrid detection in Europe using a reduced SNP panel developed for non-invasively collected samples

Jenni Harmoinen, Alina Von Thaden, Jouni Aspi, Laura Kvist, Berardino Cocchiararo, Anne Jarausch, Andrea Gazzola, Teodora Sin, Hannes Lohi, Marjo Hytönen, Ilpo Kojola, Astrid Vik Stronen, Romolo Caniglia, Federica Mattucci, Marco Galaverni, Raquel Godinho, Aritz Ruiz-González, Ettore Randi, Violeta Muñoz-Fuentes & Carsten Nowak
Background: Understanding the processes that lead to hybridization of wolves and dogs is of scientific and management importance, particularly over large geographical scales, as wolves can disperse great distances. However, a method to efficiently detect hybrids in routine wolf monitoring is lacking. Microsatellites offer only limited resolution due to the low number of markers showing distinctive allele frequencies between wolves and dogs. Moreover, calibration across laboratories is time-consuming and costly. In this study, we selected...

Data from: An intronic transposon insertion associates with a trans-species color polymorphism in Midas cichlid fishes

Claudius Kratochwil, Andreas Kautt, Alexander Nater, Andreas Härer, Yipeng Liang, Frederico Henning & Axel Meyer
Polymorphisms have fascinated biologists for a long time, but their genetic underpinnings often remained elusive. Here, we aimed to uncover the genetic basis of the gold/dark polymorphism that is eponymous of Midas cichlid fish (Amphilophus spp.) adaptive radiations in Nicaraguan crater lakes. While most Midas cichlids are of the melanic “dark morph”, about 10% of individuals lose their melanic pigmentation during their ontogeny and transition into a conspicuous “gold morph”. Using a new haplotype-resolved long-read...

Data from: Male reproductive adjustments to an introduced nest predator

Isaac Gravolin, Topi Lehtonen, Nicholas Deal, Ulrika Candolin & Bob Wong
Nest predation has a large impact on reproductive success in many taxa. Defending offspring from would-be predators can also be energetically and physiologically costly for parents. Thus, to maximize their reproductive payoffs, individuals should adjust their reproductive behaviors in relation to the presence of nest predators. However, effects of nest predator presence on parental behaviors across multiple reproductive contexts remain poorly understood, particularly in non-avian taxa. We ran a series of experiments to test how...

Taxonomic and functional diversity covary in rock pool microalgal communities despite their different drivers - Environmental and diatom data

Sonja Aarnio & Janne Soininen
We sampled 30 brackish‐watered, isolated rock pools once a month (17 May, 22 June, and 22 July) in 2016 on a granitic outcrop in the western island of Pihlajasaari (66°68′449″N, 38°40′48″E), ca. 2 km south of Helsinki, Finland on the coast of the northern Baltic Sea. We examined the drivers and covariance of taxonomic and functional diversity among the rock pool communities. We measured water pH, conductivity, and temperature in the field, and pool morphometrics...

Effects of released farmed mallards on species richness of breeding waterbirds and amphibians in natural, restored, and constructed wetlands

Pär Söderquist, Lisa Dessborn, Henric Djerf, Johan Elmberg, Gunnar Gunnarsson & Sari Holopainen
Common practices in current game management are wetland restoration and creation, as well as releases of quarry species. We studied the impact of releases of mallard ducklings on species richness of wild waterbirds and amphibians on three types of wetlands: natural, constructed and restored. Data on species richness, macrophyte cover and water characteristics (total phosphorous and pH) were collected at 32 sites in an agricultural landscape in southern Sweden. In total, 14 species of waterbirds...

Hard to catch: experimental evidence supports evasive mimicry

Erika Páez V, Janne K. Valkonnen, Keith R. Willmott, Pável Matos-Maraví, Marianne Elias & Johanna Mappes
Most research on aposematism has focused on chemically defended prey, but the signaling difficulty of capture remains poorly explored. Similar to classical Batesian and Müllerian mimicry related to distastefulness, such ‘evasive aposematism' may also lead to convergence in warning colours, known as evasive mimicry. A prime candidate group for evasive mimicry areAdelphabutterflies, which are agile insects and show remarkable colour pattern convergence. We tested the ability of naive blue tits to learn to avoid and...

Density-dependent individual variation in male attractiveness in a wild field cricket

Petri Niemelä, Stefano Tiso & Niels Dingemanse
Social environments modify a male’s ability to attract females and thus affect its fitness. Theory implies that an individual’s fitness should trade-off with its ability to cope with competition. Individuals are expected to solve this trade-off differently: some males should be more attractive at low but others instead at high density. This prediction has rarely been tested in the wild. We used an automated RFID-surveillance system to quantify for each hour of the day, over...

Exposing wind stress as a driver of fine-scale variation in plant communities

Mia Momberg, David Hedding, Miska Luoto & Peter Le Roux
The effects of temperature and precipitation, and the impacts of changes in these climatic conditions, on plant communities have been investigated extensively. The roles of other climatic factors are, however, comparatively poorly understood, despite potentially also strongly structuring community patterns. Wind, for example, is seldom considered when forecasting species responses to climate change, despite having direct physiological and mechanical impacts on plants. It is, therefore, important to understand the magnitude of potential impacts of changing...

Intraspecific genetic variation matters when predicting seagrass distribution under climate change

Zi-Min Hu, Quan-Sheng Zhang, Jie Zhang, Kass Jamie, Mammola Stefano, Fresia Pablo, Draisma Stefano, Assis Jorge, Jueterbock Alexander, Yokota Masashi & Zhixin Zhang
Seagrasses play a vital role in structuring coastal marine ecosystems, but their distributional range and genetic diversity have declined rapidly over the past decades. In order to improve conservation of seagrass species, it is important to predict how climate change may impact their ranges. Such predictions are typically made with correlative species distribution models (SDMs), which can estimate a species’ potential distribution under present and future climatic scenarios given species’ presence data and climatic predictor...

Data for: Refining the genomic location of single nucleotide polymorphism variation affecting Atlantic salmon maturation timing at a key large‐effect locus

Marion Sinclair-Waters
Efforts to understand the genetic underpinnings of phenotypic variation are becoming more and more frequent in molecular ecology. Such efforts often lead to the identification of candidate regions showing signals of association and/or selection. These regions may contain multiple genes and therefore validation of which genes are actually responsible for the signal is required. In Atlantic salmon (Salmo salar), a large‐effect locus for maturation timing, an ecologically important trait, occurs in a genomic region including...

Data set for ice nucleation by viruses and their potential for cloud glaciation

Michael Adams, Nina Atanasova, Svetlana Sofieva, Janne Ravantti, Aino Heikkinen, Zoé Brasseur, Jonathan Duplissy, Dennis Bamford & Benjamin Murray
In order to effectively predict the formation of ice in clouds we need to know which subsets of aerosol particles are effective at nucleating ice, how they are distributed and where they are from. A large proportion of ice-nucleating particles (INPs) in many locations are likely of biological origin, and some INPs are extremely small being just tens of nanometers in size. The identity and sources of such INPs are not well characterized. Here, we...

Effects of grazing on C:N:P stoichiometry attenuate from soils to plants and insect herbivores in a semi-arid grassland

Nazim Hassan, Xiaofei Li, Jianyong Wang, Hui Zhu, Duofeng Pan, Iqra Naeen, Petri Nummi, Deli Wang, Deborah Finke & Zhiwei Zhong
Understanding the processing of limiting nutrients among organisms is an important goal of community ecology. Less known is how human disturbances may alter the stoichiometric patterns among organisms from different trophic levels within communities. Here, we investigated how livestock grazing affects the C:N:P ecological stoichiometry of soils, plants (Leymus chinensis), and insect herbivores (Euchorthippus spp.) in a semi-arid grassland in northeastern China. We found that 3 years of grazing significantly enhanced soil available N and...

Automated improvement of stickleback reference genome assemblies with Lep-Anchor software

Mikko Kivikoski, Pasi Rastas, Ari Löytynoja & Juha Merilä
We describe an integrative approach to improve contiguity and haploidy of a reference genome assembly and demonstrate its impact with practical examples. With two novel features of Lep-Anchor software and a combination of dense linkage maps, overlap detection and bridging long reads we generated an improved assembly of the nine-spined stickleback (Pungitius pungitius) reference genome. We were able to remove a significant number of haplotypic contigs, detect more genetic variation and improve the contiguity of...

Data related to: Open-system evolution of a crustal-scale magma column, Klamath Mountains, California

Calvin Barnes, Nolwenn Coint, Melanie Barnes, Ariel Strickland, John Cottle, O. Ramo, Kevin Chamberlain & John Valley
Granitic magmas commonly display evidence for some level of interaction with and/or origins from crustal rocks. There is fundamental debate in the community as to the processes that control the origins of these magmas and the potential for their contamination as they pass through the crust. One approach to addressing these issues involves a combination of detailed field mapping combined with geochemical analysis of bulk-rock samples and their constituent minerals. In particular, resolution of debates...

Strain diversity and spatial distribution are linked to epidemic dynamics in host populations

Jenalle Eck, Benoit Barrès, Samuel Soubeyrand, Jukka Siren, Elina Numminen & Anna-Liisa Laine
The inherently variable nature of epidemics renders predictions of when and where infection is expected to occur challenging. Differences in pathogen strain composition, diversity, fitness, and spatial distribution are generally ignored in epidemiological modeling and are rarely studied in natural populations, yet they may be important drivers of epidemic trajectories. To examine how these factors are linked to epidemics in natural host populations, we collected epidemiological and genetic data from fifteen populations of the powdery...

Heterogeneous genetic basis of age at maturity in salmonid fishes

Charles Waters, Anthony Clemento, Tutku Aykanat, John Garza, Kerry-Ann Naish, Shawn Narum & Craig Primmer
Understanding the genetic basis of repeated evolution of the same phenotype across taxa is a fundamental aim in evolutionary biology and has applications to conservation and management. However, the extent to which interspecific life-history trait polymorphisms share evolutionary pathways remains under-explored. We address this gap by studying the genetic basis of a key life-history trait, age at maturity, in four species of Pacific salmon (genus Oncorhynchus) that exhibit intra- and interspecific variation in this trait...

Data from: Strong interactive effects of warming and insect herbivory on soil carbon and nitrogen dynamics at Subarctic tree line

Nele Meyer, Tarja Silfver, Kristiina Karhu, Kristiina Myller, Outi-Maaria Sietiö, Eero Myrsky, Elina Oksanen, Matti Rousi & Juha Mikola
Warming will likely stimulate Arctic primary production, but also soil C and N mineralization, and it remains uncertain whether the Arctic will become a sink or a source for CO2. Increasing insect herbivory may also dampen the positive response of plant production and soil C input to warming. We conducted an open-air warming experiment with Subarctic field layer vegetation in North Finland to explore the effects of warming (+3°C) and reduced insect herbivory (67% reduction...

Cuticular hydrocarbons of pupae in the ant Formica exsecta

Liselotte Sundström, Patrizia D’Ettorre, Unni Pulliainen & Nick Bos
Chemical communication is common across all organisms. Insects in particular use predominantly chemical stimuli in assessing their environment and recognizing their social counterparts. One of the chemical stimuli used for recognition in social insects, such as ants, are long-chain hydrocarbons. Next to providing waterproofing, these surface hydrocarbons serve as a signature mixture, which ants can perceive, and use to distinguish between strangers and colony mates, and to determine caste, sex, or reproductive status of another...

Data from: Genetic polymorphisms in COMT and BDNF influence synchronization dynamics of human neuronal oscillations

Felix Siebenhühner, Jaana Simola, Vladislav Myrov, Katri Kantojärvi, Tiina Paunio, J. Matias Palva, Elvira Brattico & Satu Palva
Neuronal oscillations, their inter-areal synchronization and scale-free dynamics constitute fundamental mechanisms for cognition by regulating neuronal communication. These oscillatory dynamics have large inter-individual variability that is partly heritable. However, the genetic underpinnings of oscillatory dynamics have remained poorly understood. We investigated whether local and global oscillation dynamics were influenced by polymorphisms in Catechol-O-methyltransferase (COMT) Val158Met and brain-derived neurotrophic factor (BDNF) Val66Met genes that regulate brain catecholaminergic and serotonergic levels. Resting-state magnetoencephalography (MEG) was recorded from...

Data for: Warm night temperature alters paternal allocation strategy in a North temperate zone butterfly

Elena Rosa & Marjo Saastamoinen
Warming temperatures are greatly impacting wild organisms across the globe. Some of the negative impacts of climate change can be mitigated behaviorally, for example, by changes in habitat and oviposition site choice. Temperatures are reportedly warming faster at night than during the day, yet studies assessing the impacts of increasing night temperature are rare. We used the Finnish Glanville fritillary butterfly (Melitaea cinxia) as study species and exposed adult butterflies of both sexes to warmer...
