Distribution of large carnivores in Europe 2012 - 2016: Distribution maps for Brown bear, Eurasian lynx, Grey wolf, and Wolverine

Petra Kaczensky, John D.C. Linnell, Djuro Huber, Manuela Von Arx, Henrik Andren, Urs Breitenmoser & Luigi Boitani
Regular assessments of species’ status are an essential component of conservation planning and adaptive management. They allow the progress of past or ongoing conservation actions to be evaluated and can be used to redirect and prioritise future conservation actions. Most countries perform periodic assessments for their own national adaptive management procedures or national red lists. Furthermore, the countries of the European Union have to report on the status of all species listed on the directives...

Environmental and seasonal correlates of capercaillie movement traits in a Swedish wind farm

Jim-Lino Kämmerle, Julia Taubmann, Henrik Andrén, Wolfgang Fiedler & Joy Coppes
Animals continuously interact with their environment through behavioural decisions, rendering the appropriate choice of movement speed and directionality an important phenotypic trait. Anthropogenic activities may alter animal behaviour, including movement. A detailed understanding of movement decisions is therefore of great relevance for science and conservation alike. The study of movement decisions in relation to environmental and seasonal cues requires continuous observation of movement behaviour, recently made possible by high-resolution telemetry. We studied movement traits of...

Age at first reproduction in wolves: different patterns of density dependence for females and males

Camilla Wikenros, Morgane Gicquel, Barbara Zimmermann, Øystein Flagstad & Mikael Åkesson
Age at first reproduction constitutes a key life history trait in animals and is evolutionary shaped by fitness benefits and costs of delayed versus early reproduction. The understanding of how intrinsic and extrinsic changes affects age at first reproduction is crucial for conservation and management of threatened species because of its demographic effects on population growth and generation time. For a period of 40 years in the Scandinavian wolf (Canis lupus) population, including the recolonization...

Disentangling the nonlinear effects of habitat complexity on functional responses

Julien Mocq, Pavel Soukup, Joacim Näslund & David Boukal
1. Structural complexity of habitats modifies trophic interactions by providing refuges and altering predator and prey behaviour. Nonlinear effects on trophic interaction strengths driven by these mechanisms may alter food web dynamics and community structure in response to habitat modifications. However, changes in functional response, the relationship between prey density and feeding rate, along habitat complexity (HC) gradients are little understood. 2. We quantified functional responses along a HC gradient from an entirely unstructured to...

Madsen, Carles Castaño, Daniel B. Metcalfe and Karina E. Clemmensen (Global Change Biology, 2021). In this study we reported the impacts of grazing regime and mountain birch vicinity on the abundance, diversity and community composition of the soil fungal community, and explored how the soil...

The legacy of forest disturbance on stream ecosystem functioning

André Frainer & Brendan McKie
1. Forest clearance is a pervasive disturbance worldwide, but many of its impacts are regarded as transient, diminishing in intensity as forest recovers. However, forests can take decades to centuries to recover after severe disturbances, and temporal lags in recovery of ecosystem properties for different forest habitats are mostly unknown. This includes forest streams, where most studies of the impacts of forest clearance are restricted to the first years of recovery, typically finding that temporary...

Variation in developmental rates is not linked to environmental unpredictability in annual killifishes

Piotr Rowinski, Will Sowersby, Joacim Näslund, Simon Eckerström-Liedholm, Karl Gotthard & Björn Rogell
Comparative evidence suggests that adaptive plasticity may evolve as a response to predictable environmental variation. However, less attention has been placed on unpredictable environmental variation, which is considered to affect evolutionary trajectories by increasing phenotypic variation (or bet-hedging). Here, we examine the occurrence of bet-hedging in egg developmental rates in seven species of annual killifish that originate from a gradient of variation in precipitation rates, under three treatment incubation temperatures (21°C, 23°C, and 25°C). In...

Organic fertilization suppresses aphid growth via carabids in the absence of specialist predators

Guillermo Aguilera Núñez
Biological control by natural enemies is a valuable ecosystem service. The predator community in a crop field is a combination of predators dwelling in the field and those moving into it from the surrounding landscape. The former is mainly affected by field management, the latter more by the composition of the surrounding landscape. Yet, separate and combined effects of local and landscape management on pest suppression have seldom been investigated. We set-up mesocosms within an...

Biochar increases tree biomass in a managed boreal forest, but does not alter N2O, CH4, and CO2 emissions

Roger Grau-Andrés, Melissa RA Pingree, Mats G Öquist, David A Wardle, Marie-Charlotte Nilsson & Michael J Gundale
Biochar soil amendment may provide the forestry sector with a formidable tool to simultaneously sequester carbon (C) in the soil and aboveground by enhancing plant productivity, yet several key uncertainties remain. Crucially, empirical evidence of long-term effects of biochar management on vegetation and on greenhouse gas emissions in forest ecosystems is scarce. Using a large field experiment in a young managed boreal forest in northern Sweden, we investigated the effects of biochar (applied either on...

Tree water uptake enhances nitrogen acquisition in a fertilized boreal forest – but not under nitrogen poor conditions

Nils Henriksson, Hyungwoo Lim, John Marchall, Oskar Franklin, Ross McMurtrie, Reimo Lutter, Ruth Magh, Tomas Lundmark & Torgny Näsholm
Understanding how plant water uptake interacts with acquisition of soil nitrogen (N) and other nutrients is fundamental for predicting plant responses to a changing environment, but it is an area where models disagree. We present a novel isotopic labelling approach which reveals spatial patterns of water and N uptake, and their interaction, by trees. The stable isotopes 15N and 2H were applied to a small area of the forest floor in stands with high and...

Data from: Season rather than habitat affects lynx survival and risk of mortality in the human-dominated landscape of southern Sweden

Henrik Andren, Aronsson Malin, José V. Lopez-Bao, Gustaf Samelius, Guillaume Chapron, Geir Rune Rauset, Heather Hemmingmoore & Jens Persson
Landscapes are mosaics of habitat associated with different risks and resources, including human activities, which can affect individual survival in wildlife. Different relationships between habitat characteristics and human-caused and natural mortality can result in attractive sinks. We used individual-based data from 97 Eurasian lynx (Lynx lynx) monitored for 160 exposure years to link adult survival and the risk of mortality to home range habitat characteristics in the human-dominated landscape of southern Sweden. Human-caused mortality dominated...

Site-specific SUMOylation of viral polymerase processivity factor: a way of localizingtoND10 subnuclear domains for restricted and self-controlled reproduction of herpesvirus

Shuyan Lai, Mengqiong Xu, Yaohao Wang, Ruilin Li, Chuan Xia, Sisi Xia & Jun Chen
Lytic replication of human cytomegalovirus (HCMV), a member of β-herpesvirus, is a highly complicated and organized process that requires its DNA polymerase processivity factor, UL44, the first-reported HCMV replication protein subjected to SUMO post-translational modification (PTM). SUMOylation plays a pleiotropic role in protein functions of host cells and infecting viruses. Particularly, formation of herpesviral replication compartments (RCs) upon infection is induced in proximity to ND10 subnuclear domains, the host cell’s intrinsic antiviral immune devices and...

Adaptive population structure shifts in invasive parasitic mites, Varroa destructor

Arrigo Moro, Tjeerd Blacquière, Bjorn Dahle, Vincent Dietemann, Yves Le Conte, Locke Barbara, Peter Neumann & Alexis Beaurepaire
Comparative studies of genetic diversity and population structure can shed light on the ecological and evolutionary factors governing host–parasite interactions. Even though invasive parasites are considered of major biological importance, little is known about their adaptive potential when infesting the new hosts. Here, the genetic diversification of Varroa destructor, a novel parasite of Apis mellifera originating from Asia, was investigated using population genetics to determine how the genetic structure of the parasite changed in distinct...

Predatory arthropod community composition in apple orchards: Orchard management, landscape structure and sampling method

Peter Hambäck, Mario Porcel, Marco Tasin & Ulrika Samnegård
Studies on predatory arthropods in agricultural areas seldom include Diptera other than hover flies, partly because common sampling methods are less effective for capturing species that easily fly off when disturbed. To study the effect from this bias when describing the predator community, we compared traditional beat sampling of branches and suction sampling for describing the community of predatory arthropods in Swedish apple orchards, both organic orchards and orchards using integrated pest management. Our results...

Precipitation regime controls bryosphere carbon cycling similarly across contrasting ecosystems

Roger Grau-Andrés, David Wardle, Marie-Charlotte Nilsson & Paul Kardol
In arctic and boreal ecosystems, ground bryophytes play an important role in regulating carbon (C) exchange between vast belowground C stores and the atmosphere. Climate is changing particularly fast in these high-latitude regions, but it is unclear how altered precipitation regimes will affect C dynamics in the bryosphere (i.e., the ground moss layer including senesced moss, litter, and associated biota) and the closely associated upper humus layer, and how these effects will vary across contrasting...

All data for: Megaherbivore impacts on ecosystem and Earth system functioning: The current state of the science

Olli Hyvärinen
Megaherbivores (adult body mass >1000 kg) are suggested to disproportionately shape ecosystem and Earth system functioning. We systematically reviewed the empirical basis for this general thesis and for the more specific hypotheses that (i) megaherbivores have disproportionately larger effects on Earth system functioning than their smaller counterparts, (ii) this is true for all extant megaherbivore species and (iii) their effects vary along environmental gradients. We furthermore explored possible biases in our understanding of megaherbivore impacts....

Naivety dies with the calf: Learning effects in a heavily harvested ungulate

Lukas Graf, Henrik Thurfjell, Göran Ericsson & Wiebke Neumann
In animals, habitat selection and movement strategies may affect survival and this may be key agents in selection affection the evolution of a species. To test for learning capabilities of previous experience of hunting in a long-lived, solitary and heavily harvested ungulate, we combined longitudinal GPS-data from 84 female moose (Alces alces) with data on calf and adult survival. We tested the prediction that long-lived moose individuals would adapt their behavior over time due to...

UK dogs data from: Genome-wide association studies for canine hip dysplasia in single and multiple populations – implications and potential novel risk loci

Juliane Friedrich, Shizhi Wang, Erling Strandberg, Per Arvelius, Dylan N Clements & Pamela Wiener
Background: Association mapping studies of quantitative trait loci (QTL) for canine hip dysplasia (CHD) can contribute to the understanding of the genetic background of this common and debilitating disease and might contribute to its genetic improvement. The power of association studies for CHD is limited by relatively small sample numbers for CHD records within countries, suggesting potential benefits of joining data across countries. However, this is complicated due to the use of different scoring systems...

Prognostic and immunological significance of metastasis associated lung adenocarcinoma transcript 1 among different kinds of cancers

Lili Guo, Xiuwen Zhang, Hongli Pan, Yang Li, Jing Wang, Lin Li, Yafang Dong, Xinxin Du, Jun Chen & Fengjie Guo
LncRNAs belong to the type of noncoding RNA transcripts, which exceed 200 nucleotides in size. MALAT1 as one of the earlier identified lncRNAs in cancer is investigated by more and more scientific researchers. Expression, clinical significance and function of MALAT1 in pan-cancer exist as big difference. To detect the expression and clinical significance of MALAT1 gene precisely and comprehensively among different kinds of cancers, some classical databases such as GEPIA, TIMER, KM Plotter, and PrognoScan...

Immigration credit of temperate forest herbs in fragmented landscapes – implications for restoration of habitat connectivity

Jörg Brunet, Per-Ola Hedwall, Jessica Lindgren & Sara Cousins
1. In many agricultural landscapes, it is important to restore networks of forests to provide habitat and stepping stones for forest specialist taxa. More knowledge is, however, needed on how to facilitate the immigration of such taxa in restored forest patches. Here, we present the first chronosequence study to quantify the dynamics of immigration credits of forest specialist plants in post-arable forest patches. 2. We studied the distribution of herbaceous forest specialist plant species in...

Plant diversity ameliorates the evolutionary development of fungicide resistance in an agricultural ecosystem

Lina Yang, Oswald Nkurikiyimfura, Zhechao Pan, Yanping Wang, Abdul Waheed, Ruey-Shyang Chen, Jeremy Burdon, Qijun Sui & Jiasui Zhan
1. Evolution of fungicide resistance in agricultural and natural ecosystems is associated with the biology of pathogens, the chemical property and application strategies of the fungicides. The influence of ecological factors such as host diversity on the evolution of fungicide resistance has been largely overlooked but is highly relevant to social and natural sustainability. In this study, we used an experimental evolution approach to understand how host population heterogeneity may affect the evolution of fungicide...

The effects of host plant species and larval density on immune function in the polyphagous moth Spodoptera littoralis

Kristina Karlsson Green
Immune functions are costly and immune investment is usually dependent on the individual’s condition and resource availability. For phytophagous insects, host plant quality has large effects on performance, e.g. growth and survival, and may also affect their immune function. Polyphagous insects often experience a large variation in quality among different host plant species, and their immune investment may thus vary depending on which host plant species they develop on. Larvae of the polyphagous moth Spodoptera...

Archival and modern DNA SNP data of 13 Baltic salmon populations

Johan Östergren
Intra-species genetic homogenization arising from anthropogenic impacts is a major threat for biodiversity. However, few taxa have sufficient historical material to systematically quantify long-term genetic changes. Using archival DNA collected over ~100 years, we assessed spatio-temporal genetic change in Atlantic salmon populations across the Baltic Sea, an area heavily impacted by hydropower exploitation and associated large-scale mitigation stocking. Analysis was carried out by screening 82 SNPs in 1680 individuals from 13 Swedish rivers. We found...
