Carnivores tend to exhibit a lack of (or less pronounced) genetic structure at continental scales in both a geographic and temporal sense using various mitochondrial DNA markers on modern and/or ancient specimens. This tends to confound the identification of refugial areas and post-glacial colonization patterns in this group. In this study we used Genotyping-by-Sequencing (GBS) to reconstruct the phylogeographic history of a widespread carnivore, the red fox (Vulpes vulpes), in Europe by investigating broad-scale patterns...

Short-term exposure to heatwave-like temperatures affects learning and memory in bumblebees

Maxence Gérard
Global warming has been identified as a key driver of bee declines around the world. While it is clear that elevated temperatures during the spring and summer months – the principal activity period of many bee species – is a factor in this decline, exactly how temperature affects bee survival is unknown. In vertebrates, there is clear evidence that elevated ambient temperatures impair cognition but whether and how heat affects the cognitive abilities of invertebrates...

Exposure to elevated temperature during development affects bumblebee foraging behavior

Maxence Gérard, Bérénice Cariou, Maxime Henrion, Charlotte Descamps & Emily Baird
Bee foraging behavior provides a pollination service that has both ecological and economic benefits. However, bee population decline could directly affect the efficiency of this interaction. Among the drivers of this decline, global warming has been implicated as an emerging threat but exactly how increasing temperatures affect bee foraging behavior remains unexplored. Here, we assessed how exposure to elevated temperatures during development affects the foraging behavior and morphology of workers from commercial and wild Bombus...

Data from: High spatiotemporal variability of methane concentrations challenges estimates of emissions across vegetated coastal ecosystems

Florian Roth, Xiaol Sun, Marc Geibel, John Prytcherch, Volker Brüchert, Stefano Bonaglia, Elias Broman, Francisco Nascimento, Christoph Humborg & Alf Norkko
Coastal methane (CH4) emissions dominate the global ocean CH4 budget and can offset the “blue carbon” storage capacity of vegetated coastal ecosystems. However, current estimates lack systematic, high-resolution, and long-term data from these intrinsically heterogeneous environments, making coastal budgets sensitive to statistical assumptions and uncertainties. Using continuous CH4 concentrations, δ13C-CH4 values, and CH4 sea-air fluxes across four seasons in three globally pervasive coastal habitats, we show that the CH4 distribution is spatially patchy over meter-scales...

Niche differentiation within a cryptic pathogen complex: climatic drivers and hyperparasitism at multiple spatial scales

Maria Faticov
Pathogens are embedded in multi-trophic food webs, which often include co-occurring cryptic species within the same pathogen complex. Nonetheless, we still lack an understanding of what dimensions of the ecological niche might allow these cryptic species to coexist. We explored the role of climate, host characteristics (tree autumn phenology) and attack by the fungal hyperparasite Ampelomyces (a group of fungi attacking plant pathogens) in defining the niches of three powdery mildew species (Erysiphe alphitoides, E....

DNA-based assessment of environmental degradation in an unknown fauna: the freshwater macroinvertebrates of the Indo-Burmese hotspot

, Alfred Burian, Thomas Creedy & Alfried Vogler
New methods are required for biomonitoring of poorly known tropical ecosystems, but biological assessments of environmental status are limited by insufficient information on taxonomy, composition, and ecology of local communities. The current work applies DNA-based assessment to establish the impact of various types of anthropogenic disturbances on the freshwater macroinvertebrates in an understudied biodiversity hotspot in South Asia, an area that attracts increasing attention for the loss of aquatic ecosystems. We sampled 16 river systems...

Simultaneous selection on vegetative and reproductive phenology in a perennial herb

Elsa Fogelström, Giulia Zacchello & Johan Ehrlén
The timing of different life history events are often correlated, and selection might only rarely be exerted independently on the timing of a single event. In plants, phenotypic selection has often been shown to favour earlier flowering. However, little is known about to what extent this selection acts directly vs. indirectly via vegetative phenology, and if selection on the two traits is correlational. We estimated direct, indirect and correlational phenotypic selection on vegetative and reproductive...

The biogeography of community assembly: latitude and predation drive variation in community trait distribution in a guild of epifaunal crustaceans

Collin Gross, Collin Gross, J Duffy, Kevin Hovel, Melissa Kardish, Pamela Reynolds, Christoffer Boström, Katharyn Boyer, Mathiew Cusson, Johan Eklöf, Aschwin Engelen, Klemens Eriksson, Joel Fodrie, John Griffin, Clara Hereu, Masakazu Hori, A Randall Hughes, Mikhail Ivanov, Pablo Jorgensen, Claudia Kruschel, Kun-Seop Lee, Jonathan Lefcheck, Karen McGlathery, Per-Olav Moksnes, Masahiro Nakaoka … & Jay Stachowicz
While considerable evidence exists of biogeographic patterns in the intensity of species interactions, the influence of these patterns on variation in community structure is less clear. Using a model selection approach on measures of trait dispersion in crustaceans associated with eelgrass (Zostera marina) spanning 30º of latitude in two oceans, we found that dispersion strongly increased with increasing predation and decreasing latitude. Ocean and epiphyte load appeared as secondary predictors; Pacific communities were more overdispersed...

Plant biodiversity declines with increasing coffee yield in Ethiopia’s coffee agroforests

Beyene Zewdie, Ayco Tack, Biruk Ayalew, Melaku Wondafrash, Sileshi Nemomissa & Kristoffer Hylander
1. Tropical agroforestry systems provide farmers with resources for their livelihoods, but are also well recognized as refuges for biodiversity. However, the relationship between yield and biodiversity might be negative in these systems, reflecting a potential trade-off between managing for increased yield or biodiversity. The potential for synergies will depend partly on the shape of the biodiversity-yield relationship, where a concave relationship suggests a faster decline of biodiversity with increasing yields than a linear or...

Data from: Loss-of-heterozygosity facilitates a fitness valley crossing in experimentally evolved multicellular yeast

Beatriz Baselga-Cervera, Noah Gettle & Michael Travisano
These data sets are generated to investigate a simple evolutionary landscape that arises from underdominance at a single locus where the fitness valley consists of only one less-fit genotype. We make use of an experimental system previous evolved in the laboratory, the Saccharomyces cerevisiae snowflake system. This system was experimentally selected resulting in a significant evolutionary shift, the transition from uni-to-multicellularity in asexual diploid populations. We carried out the phenotypic and fitness characterization of the...

Experimental sexual selection affects the evolution of physiological and life history traits

Martin D. Garlovsky, Luke Holman, Andrew L. Brooks, Rhonda R. Snook & Zorana K. Novicic
Sexual selection and sexual conflict are expected to affect all aspects of the phenotype, not only traits that are directly involved in reproduction. Here, we show coordinated evolution of multiple physiological and life history traits in response to long-term experimental manipulation of the mating system in populations of Drosophila pseudoobscura. Development time was extended under polyandry relative to monogamy in both sexes, potentially due to higher investment in traits linked to sexual selection and sexual...

More recently, a sub-type of VMS associated...

Allometric scaling of a superposition eye optimises sensitivity and acuity in large and small hawkmoths

Anna Stöckl, Anna Stöckl, Rebecca Grittner, Gavin Taylor, Christoph Rau, Andrew J. Bodey, Almut Kelber & Emily Baird
Animals vary widely in body size within and across species. This has consequences for the function of organs and body parts in both large and small individuals. How these scale, in relation to body size, reveals evolutionary investment strategies, often resulting in trade-offs between functions. Eyes exemplify these trade-offs, as they are limited by their absolute size in two key performance features: sensitivity and spatial acuity. Due to their size polymorphism, insect compound eyes are...

Spring phenology and pathogen infection affect multigenerational plant attackers throughout the growing season

Álvaro Gaytán, Karl Gotthard & Ayco Tack
Climate change has been shown to advance spring phenology, increase the number of insect generations per year (multivoltinism), and increase pathogen infection levels. However, we lack insights into the effects of plant spring phenology and the biotic environment on the preference and performance of multivoltine herbivores and whether such effects extend into the later part of the growing season. To this aim, we used a multifactorial growth chamber experiment to examine the influence of spring...

We report a time series of ice-nucleating particle concentration spectra measured on a cruise to the North Pole.

Resource-dependent investment in male sexual traits in a viviparous fish

Erika Fernlund Isaksson, Charel Reuland, Ariel Kahrl, Alessandro Devigili & John Fitzpatrick
Exaggerated and conspicuous sexually selected traits are often costly to produce and maintain. Costly traits are expected to show resource-dependent expression, since limited resources prevent animals from investing maximally in multiple traits simultaneously. However, there may be critical periods during an individual’s life where the expression of traits is altered if resources are limited. Moreover, costly sexual traits may arise from sexual selection acting both before (pre-copulatory) and after mating (post-copulatory). Gaining a robust understanding...

Temporal and spatial changes in benthic invertebrate trophic networks along a taxonomic richness gradient

Julie Garrison, Marie Nordström, Jan Albertsson & Francisco Nascimento
Species interactions underlie most ecosystem functions and are important for understanding ecosystem changes. Representing one type of species interaction, trophic networks were constructed from biodiversity monitoring data and known trophic links to assess how ecosystems have changed over time. The Baltic Sea is subject to many anthropogenic pressures, and low species diversity makes it an ideal candidate for determining how pressures change food webs. In this study, we used benthic monitoring data from 20 years...

Genetic composition and diversity of Arabica coffee in the crop’s center of origin and its impact on four major fungal diseases

Beyene Hailu & Yves Bawin
Conventional wisdom states that genetic variation reduces disease levels in plant populations. Nevertheless, crop species have been subject to a gradual loss of genetic variation through selection for specific traits during breeding, thereby increasing their vulnerability to biotic stresses such as pathogens. We explored how genetic variation in Arabica coffee sites in southwestern Ethiopia was related to the incidence of four major fungal diseases. Sixty sites were selected along a gradient of management intensity, ranging...

Are behavioural responses to eyespots in sticklebacks influenced by the visual environment? An experimental examination

John L. Fitzpatrick, Evelina Juntorp, Madicken Åkerman & John L. Fitzpatrick
Eyespots are taxonomically widespread colour patterns consisting of large concentric rings that are commonly assumed to protect prey by influencing the behaviours of predators. Although there is ample experimental evidence supporting an anti-predator function of eyespots in terrestrial animals, whether eyespots have a similar deterring function in aquatic animals remains unclear. Furthermore, studies in terrestrial systems suggest that the protective function of eyespots depends on ambient light conditions where predators encounter them, but this effect...

Niche partitioning between planktivorous fish in the pelagic Baltic Sea assessed by DNA metabarcoding, qPCR and microscopy: Data and Analyses

Andreas Novotny, Kinlan Jan, Jan Dierking & Monika Winder
Marine communities undergo rapid changes because of human-induced ecosystem pressures. The Baltic Sea pelagic food web has experienced several regime shifts during the past century, resulting in a system where competition between planktivorous mesopredators is assumed to be high. While the two clupeids sprat and herring reveal signs of competition, the stickleback population has increased drastically during the past decades. Here, we investigate diet overlap between the three dominating planktivorous fish in the Baltic Sea,...

THREE-DIMENSIONAL HINDCAST OF NITROGEN AND PHOSPHORUS BIOGEOCHEMICAL DYNAMICS IN LAKE ONEGO ECOSYSTEM, 1985-2015 PART II. SEASONAL DYNAMICS AND SPATIAL FEATURES; INTEGRAL FLUXES

O. P. Savchuk, A.V. Isaev & N.N. Filatov
A three-dimensional coupled hydrodynamical biogeochemical model of the nitrogen and phosphorus cycles has been used for a long-term reanalysis of the Lake Onego ecosystem. The comparison between simulation and sparse irregular observations, presented in the first part of this paper, demonstrated plausibility of the reconstructed temporal and spatial features of biogeochemical dynamics at a long-term scale, while seasonal dynamics of variables and fluxes are presented here. As new regional phenological knowledge, the reanalysis quantifies that...

Data from: Single, but not dual, attack by a biotrophic pathogen and sap-sucking insect affects the oak leaf metabolome

Laura J. A. Van Dijk, Emilia D. E. Regazzoni, Benedicte R. Albrectsen, Johan Ehrlén, Ahmed Abdelfattah, Hans Stenlund, Katharina Pawlowski & Ayco J. M. Tack
Plants interact with a multitude of microorganisms and insects, both belowand above ground, which might influence plant metabolism. Despite this, we lack knowledge of the impact of natural soil communities and multiple aboveground attackers on the metabolic responses of plants, and whether plant metabolic responses to single attack can predict responses to dual attack. We used untargeted metabolic fingerprinting (gas chromatographymass spectrometry, GC-MS) on leaves of the pedunculate oak, Quercus robur, to assess the metabolic...

Phenotypic plasticity is aligned with phenological adaptation on micro- and macroevolutionary timescales

Stephen De Lisle, Maarit Mäenpää & Erik Svensson
In seasonally-variable environments, phenotypic plasticity in phenology may be critical for adaptation to fluctuating environmental conditions. Using an 18-generation longitudinal dataset from natural damselfly populations, we show that phenology has strongly advanced. Individual fitness data suggest this is likely an adaptive response towards a temperature-dependent optimum. A laboratory experiment revealed that developmental plasticity qualitatively matches the temperature-dependence of selection, partially explaining observed advance in phenology. Expanding our analysis to the macroevolutionary level, we use a...

Differences in decompression of the high-pressure Cycladic Blueschist Unit (Naxos Island, Greece): what can inclusions tell us?

Alexandre Peillod , Jarosław Majka , Uwe Ring , Kirsten Drüppel , Clifford Patten , Andreas Karlsson , Adam Włodek & Elof Tehler
Determining the tectonic evolution and thermal structure of a tectonic unit that experiences a subduction-related pressure temperature (P-T) loop is challenging. Within a single unit, P-T conditions can vary from top to bottom which can be only revealed by detailed petrological work. We present micropetrological data of the middle section of the Cycladic Blueschist Unit (CBU) in Naxos, Greece, which indicate a different P-T loop than the top of the section. In the middle section,...

Longer and warmer prewinter periods reduce post-winter fitness in a diapausing insect

Matthew Nielsen, Philipp Lehmann & Karl Gotthard
1. Diapause is considered an important adaptation for survival of winter; however, insects often enter diapause long before its onset. Thus, diapausing insects must also be able to survive these prewinter conditions which warm temperatures could make quite energetically taxing despite relative inactivity. 2. We tested for both immediate and delayed fitness effects of prewinter conditions in diapausing Pieris napi butterfly pupae, experimentally exposing them to different prewinter treatments in a factorial design. We placed...
