First come, first served: possible role for priority effects in marine populations under different degrees of dispersal potential

Christiaan De Leeuw, Katja Peijnenburg, Rosemary Gillespie, Diede Maas, Naoto Hanzawa, Yosephine Tuti, Abdul Toha, Ludi Aji & Leontine Becking
Aim Studying clearly delineated populations in marine lakes, islands of sea, we investigate the interplay of habitat size, immigration, and priority effects in shaping marine population genetic structure. Location Marine lakes and coastal locations in Indonesia, Palau, Papua New-Guinea and Australia. Taxon Mussels (Mytillidae, Brachidontes spp.) Methods Populations were sampled from four coastal locations and 22 marine lakes of similar age (~8,000 years), yet differing in size (0.04 - 4.7 km2) and degree of connection...

Extra-territorial forays by great tits are associated with dawn song in unexpected ways

Nina Bircher, Kees Van Oers, Camilla A. Hinde & Marc Naguib
Conspicuous male signals often play an important role in both attracting mates and deterring rivals. In territorial species with extra-pair mating, female and male forays to other territories may be an important component underlying female choice and male mating success and might be influenced by male advertisement signals. Yet, whether off-territory foraying is associated with male signals is still not well understood. Here, we tested how female and male forays are associated with short-range visual...

Data from: Seagrass coastal protection services reduced by invasive species expansion and megaherbivore grazing

Rebecca K. James, Marjolijn J. A. Christianen, Marieke Van Katwijk, Jaco De Smit, , Peter Herman & Tjeerd Bouma
1. Seagrasses provide an important ecosystem service by creating a stable erosion-resistant seabed that contributes to effective coastal protection. Variable morphologies and life history strategies, however, are likely to impact the sediment stabilisation capacity of different seagrass species. We question how opportunistic invasive species and increasing grazing by megaherbivores may alter sediment stabilisation services provided by established seagrass meadows, using the Caribbean as a case study. 2. Utilising two portable field-flumes that simulate unidirectional and...

Quantitative genetics of wing morphology in the parasitoid wasp Nasonia vitripennis: hosts increase sibling similarity

Shuwen Xia, Bart Pannebakker, Martien A.M. Groenen, Bas Piter Zwaan & Piter Bijma
The central aim of evolutionary biology is to understand patterns of genetic variation between species and within populations. To quantify the genetic variation underlying intraspecific differences, estimating quantitative genetic parameters of traits is essential. In Pterygota, wing morphology is an important trait affecting flight ability. Moreover, gregarious parasitoids such as Nasonia vitripennis oviposit multiple eggs in the same host, and siblings thus share a common environment during their development. Here we estimate the genetic parameters...

Modulation of the Tomato Fruit Metabolome by LED Light (GCMS and LCMS datasets)

Nikolaos Ntagkas, Ric C. H. De Vos, Ernst J. Woltering, Celine C. S. Nicole, Caroline Labrie & Leo F. M. Marcelis
Metabolic profiles of tomatoes change during ripening and light can modulate the activity of relevant biochemical pathways. We investigated the effects of light directly supplied to the fruits, on the metabolome of the fruit pericarp during ripening. Mature green tomatoes were exposed to well-controlled conditions with light as the only varying factor; control fruits were kept in darkness. In Experiment 1 the fruits were exposed to either white light or darkness for 15 days. In...

Data from: Spatial scale, neighbouring plants and variation in plant volatiles interactively determine the strength of host-parasitoid relationships

Yavanna Aartsma, Silvia Pappagallo, Wopke Van Der Werf, Marcel Dicke, Felix Bianchi & Erik Poelman
Species-specific responses to the environment can moderate the strength of interactions between plants, herbivores and parasitoids. However, the ways in which characteristics of plants, such as genotypic variation in herbivore induced volatiles (HIPVs) that attract parasitoids, affect trophic interactions in different contexts of plant patch size and plant neighbourhood is not well understood. We conducted a factorial field experiment with white cabbage (Brassica oleracea) accessions that differ in the attractiveness of their HIPVs for parasitoids,...

Arbuscular mycorrhizal symbiosis increases P uptake and productivity of mixtures of maize varieties compared to monocultures

Gu Feng, Xinxin Wang, Ellis Hoffland, Gu Feng & Thomas Kuyper
Ecological intensification seeks to achieve crop yield increases through intensifying complementary or facilitative interactions between plant species or varieties. Different species of arbuscular mycorrhizal fungi (AMF) exhibit niche differentiation and show selectivity towards certain plants, which can further enhance complementarity. It is not clear whether in the presence of one AMF species, where mycelial networks connect crop species, opportunities for complementarity effects may be reduced. We grew monocultures and mixtures of maize varieties in a...

Parasite infestation influences life-history but not boldness behavior in placental live-bearing fish

Andres Hagmayer, Andrew Furness & Bart Pollux
Parasites can negatively affect the reproductive success of hosts. Placental species may be particularly susceptible, because parasite-induced stress during pregnancy could potentially influence embryo development. Here we examine the consequences of a trematode infestation (black spot disease, BSD) for fetal development and adult behavior in 19 natural populations of the placental live-bearing fish species Poeciliopsis retropinna (Poeciliidae) in Costa Rica. First, we observed substantial variation in parasite infestation among populations which correlated with a number...

Resistance-recovery tradeoff of soil microbial communities under altered rain regimes: An experimental test across European agroecosystems

Gabin Piton, Arnaud Foulquier, Laura B. Martinez-García, Nicolas Legay, Lijbert Brussaard, Katarina Hedlund, Pedro Martins Da Silva, Eduardo Nascimento, Filipa Reis, José Paulo Sousa, Jean Christophe Clement & Gerlinde De Deyn
With the increased occurrence of climate extremes, there is an urgent need to better understand how management strategies affect the capacity of the soil microbial community to maintain its ecosystem functions (e.g. nutrient cycling). To address this issue, intact monoliths were extracted from conventional and ecological managed grasslands in three countries across Europe and exposed under common air condition (temperature and moisture) to one of three altered rain regimes (dry, wet and intermittent wet/dry) as...

Lure, retain, and catch malaria mosquitoes. How heat and humidity improve odour-baited trap performance

Antoine Cribellier
Background: When seeking a human for a blood meal, mosquitoes use several cues to detect and find their hosts. From this knowledge, counter-flow odour-baited traps have been developed that use a combination of CO2, odour-blend, visual cues and circulating airflow to attract and capture mosquitoes. Initially developed for monitoring, these traps are now also being considered as promising vector control tools. These traps are attractive to host-seeking mosquitoes, but their capture efficiency is low. It...

Identification and characterization of QTLs for fruit quality traits in peach through a multi-family approach

Zena Rawandoozi, Timothy P. Hartmann, Silvia Carpenedo, Ksenija Gasic, Cassia Da Silva Linge, Lichun Cai, Eric Van De Weg & David H. Byrne
Background Fruit quality traits have a significant effect on consumer acceptance and subsequently on peach (Prunus persica (L.) Batsch) consumption. Determining the genetic bases of key fruit quality traits is essential for the industry to improve fruit quality and increase consumption. Pedigree-based analysis across multiple peach pedigrees can identify the genomic basis of complex traits for direct implementation in marker-assisted selection. This strategy provides breeders with better-informed decisions and improves selection efficiency and, subsequently, saves...

Predator defense is shaped by risk, brood value and social group benefits in a cooperative breeder

Niki Teunissen, Sjouke Kingma & Anne Peters
Predation is a major cause of mortality and nest failure in birds. Cooperative predator defense can enhance nest success and adult survival, but since it is inherently risky, dynamic risk assessment theory predicts that individuals modify defense behavior according to risk posed by the predator. Parental investment theory on the other hand predicts that reproductive payoffs (brood value) determine investment in nest defense. We propose that in cooperative breeders, fitness benefits deriving from survival of...

Mixed ancestry from wild and domestic lineages contributes to the rapid expansion of invasive feral swine

Timothy Smyser, Michael Tabak, Chris Slootmaker, Michael Robeson, Ryan Miller, Mirte Bosse, Hendrik-Jan Megens, Martien Groenen, Samuel Paiva, Danielle Assis De Faria, Harvey Blackburn, Brandon Schmit & Antoinette Piaggio
Invasive alien species are a significant threat to both economic and ecological systems. Identifying processes that give rise to invasive populations is essential for implementing effective control strategies. We conducted an ancestry analysis of invasive feral swine (Sus scrofa, Linnaeus, 1758), a highly destructive ungulate that is widely distributed throughout the contiguous United States, to describe introduction pathways, sources of newly-emergent populations, and processes contributing to an ongoing invasion. Comparisons of high-density single nucleotide polymorphism...

An empirical evaluation of camera trap study design: how many, how long, and when?

Roland Kays, Brian Arbogast, Megan Baker-Whatton, Chris Beirne, Hailey Boone, Mark Bowler, Santiago Burneo, Michael Cove, Ping Ding, Santiago Espinosa, André Gonçalves, Christopher Hansen, Patrick Jansen, Joseph Kolowski, Travis Knowles, Marcela Lima, Joshua Millspaugh, William McShea, Krishna Pacifici, Arielle Parsons, Brent Pease, Francesco Rovero, Fernanda Santos, Stephanie Schuttler, Douglas Sheil … & Wilson Spironello
1. Camera traps deployed in grids or stratified random designs are a well-established survey tool for wildlife but there has been little evaluation of study design parameters. 2. We used an empirical subsampling approach involving 2225 camera deployments run at 41 study areas around the world to evaluate three aspects of camera trap study design (number of sites, duration and season of sampling) and their influence on the estimation of three ecological metrics (species richness,...

Fungal root-endophytes influence plants in a species-specific manner that depends on plant's growth stage

Stefan Geisen, Freddy Ten Hooven, Olga Kostenko, Basten Snoek & Wim Van Der Putten
The mycobiome (fungal microbiome) influences plants— from seed germination to full maturation. While many studies on fungal-plant interaction studies have focused on known mutualistic and pathogenic fungi, the functional role of ubiquitous endophytic fungi remains little explored. We examined how root-inhabiting fungi (endophytes) influence range expanding plant species. We isolated endophytes from three European intra-continental range-expanders and three congenerics that are native both in the range-expander’s original (southern Europe) and new (northern Europe) range. To...

Data from: Modulation of yaw stability with an unstable rigid body and a stabilising caudal fin in the yellow boxfish (Ostracion cubicus)

Pim G. Boute, Sam Van Wassenbergh & Eize J. Stamhuis
Despite that boxfishes have a rigid carapace that restricts body undulation, they are highly manoeuvrable and manage to swim with remarkably dynamic stability. Recent research has indicated that the rigid body shape of boxfishes shows an inherently unstable response in its rotations caused by course-disturbing flows. Hence, any net stabilising effect should come from the fish’s fins. The aim of the current study was to determine the effect of the surface area and orientation of...

The role of fine‐root mass, specific root length and lifespan in tree performance: a whole‐tree exploration

Monique Weemstra, Natasa Kiorapostolou, Jasper Van Ruijven, Liesje Mommer, Jorad De Vries & Frank Sterck
1. The root economics spectrum (RES) hypothesis predicts that fast-growing tree species have short-lived roots with high specific root length (SRL) to allow rapid resource uptake, and opposite trait expressions for slow-growing species. Yet, the mixed support for this hypothesis suggests that trees can adopt alternative strategies to increase resource uptake, besides an increase in SRL. 2. We combined a novel mechanistic whole-tree model and empirical fine-root data of ten tree species to test the...

Marine stepping-stones: Connectivity of Mytilus edulis populations between offshore energy installations

Joop W.P. Coolen, Arjen R. Boon, Richard Crooijmans, Hilde Van Pelt, Frank Kleissen, Daan Gerla, Jan Beermann, Silvana N.R. Birchenough, Lisa E. Becking & Pieternella C. Luttikhuizen
Recent papers postulate that epifaunal organisms use artificial structures as stepping-stones to spread to areas that are too distant to reach in a single generation. With thousands of artificial structures present in the North Sea, we test the hypothesis that these structures are connected by water currents and act as an interconnected reef. Population genetic structure of the Blue mussel, Mytilus edulis was expected to follow a pattern predicted by particle tracking models (PTM). Correlation...

Limited mass-independent individual variation in resting metabolic rate in a wild population of snow voles (Chionomys nivalis)

Andres Hagmayer, Glauco Camenisch, Cindy Canale, Erik Postma & Timothée Bonnet
Resting metabolic rate (RMR) is a potentially important axis of physiological adaptation to the thermal environment. However, our understanding of the causes and consequences of individual variation in RMR in the wild is hampered by a lack of data, as well as analytical challenges. RMR measurements in the wild are generally characterized by large measurement errors and a strong dependency on mass. The latter is problematic when assessing the ability of RMR to evolve independently...

Predation risk shapes the degree of placentation in natural populations of live-bearing fish

Andres Hagmayer, Andrew I. Furness, David N. Reznick, Myrthe L. Dekker & Bart J. A. Pollux
The placenta is a complex life-history trait that is ubiquitous across the tree of life. Theory proposes that the placenta evolves in response to high performance-demanding conditions by shifting maternal investment from pre- to post-fertilization, thereby reducing a female’s reproductive burden during pregnancy. We test this hypothesis by studying populations of the fish species Poeciliopsis retropinna in Costa Rica. We found substantial variation in the degree of placentation among natural populations associated with predation risk:...

Data from: Neighbourhood-dependent root distributions and the consequences on root separation in arid ecosystems

Bin J. W. Chen, Chi Xu, Mao-Song Liu, Zheng Y. X. Huang, Ming-Juan Zhang, Jian Tang & Niels P. R. Anten
1. Inter-specific root separation is an important example of spatial niche differentiation that drives species coexistence in many ecosystems. Particularly under water-stressed conditions, it is believed to be an inevitable outcome of species interactions. However, evidence for and against this idea has been found. So far, studies aiming at reconciling the debate mainly focus on abiotic determinants. It remains unclear if and to what extent root separation depends on the type and growth form of...

Data from: A critical analysis of the potential for EU Common Agricultural Policy measures to support wild pollinators on farmland

Lorna Cole, David Kleijn, Lynn Dicks, Jane Stout, Simon Potts, Matthias Albrecht, Mario Balzan, Ignasi Bartomeus, Penelope Bebeli, Danilo Bevk, Jacobus Biesmeijer, Róbert Chlebo, Anželika Dautartė, Nikolaos Emmanouil, Chris Hartfield, John Holland, Andrea Holzschuh, Nieke Knoben, Anikó Kovács-Hostyánszki, Yael Mandelik, Heleni Panou, Robert Paxton, Theodora Petanidou, Miguel Pinheiro De Carvalho, … & Jeroen Scheper
1. Agricultural intensification and associated loss of high-quality habitats are key drivers of insect pollinator declines. With the aim of decreasing the environmental impact of agriculture, the 2014 EU Common Agricultural Policy (CAP) defined a set of habitat and landscape features (Ecological Focus Areas: EFAs) farmers could select from as a requirement to receive basic farm payments. To inform the post-2020 CAP, we performed a European-scale evaluation to determine how different EFA options vary in...

Raw data for: No reproductive benefits of dear enemy recognition in a territorial songbird

Michael Reichert, Jodie Crane, Gabrielle Davidson, Eileen Dillane, Ipek Kulahci, James O'Neill, Kees Van Oers, Ciara Sexton & John Quinn
Territorial animals often learn to distinguish their neighbors from unfamiliar conspecifics. This cognitive ability facilitates the dear enemy effect, where individuals respond less aggressively to neighbors than to other individuals, and is hypothesized to be adaptive by reducing unnecessary aggressive interactions with individuals that are not a threat to territory ownership. A key prediction of this hypothesis, that individuals with better ability to learn to recognize neighbors should have higher fitness, has never been tested....
