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...

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: 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...

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...

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...

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,...

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...

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...

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...

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...

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...

Data from: Population- and species-based variation of webworm-parasitoid interactions in hogweeds (Heracelum spp.) in the Netherlands

Jeffrey Harvey, Rieta Gols & Paul Ode
In three Dutch populations of the native small hogweed (Heracleum sphondylium), and one of the invasive giant hogweed (H. mantegazzianum), interactions between a specialist herbivore, the parsnip webworm (Depressaria radiella), and its associated parasitoids were compared during a single growing season. We found plant population and/or host plant species-related differences in the abundance of moth pupae, the specialist polyembryonic endoparasitoid, Copidosoma sosares, the specialist pupal parasitoid, Barichneumon heracliana, and a potential hyperparasitoid of C. sosares,...

Data from: Adapted dandelions trade dispersal for germination upon root herbivore attack

Zoe Bont, Marc Pfander, Christelle Robert, Meret Huber, Erik Poelman, Ciska Raaijmakers & Matthias Erb
A plant’s offspring may escape unfavourable local conditions through seed dispersal. Whether plants use this strategy to escape insect herbivores is not well understood. Here, we explore how different dandelion (Taraxacum officinale agg.) populations, including diploid outcrossers and triploid apomicts, modify seed dispersal in response to root herbivore attack by their main root-feeding natural enemy, the larvae of the common cockchafer Melolontha melolontha. In a manipulative field experiment, root herbivore attack increased seed dispersal potential...

The contribution of semi-natural habitats to biological control is dependent on sentinel prey type

Niamh Mary McHugh, Stephen Moreby, Marjolein Lof, Wopke Van Der Werf & John Holland
It is widely recognized that landscape factors affect the biological control of weed seeds and insect pests in arable crops, but landscape effects have been found to be inconsistent between studies. Here, we compare six different types of sentinels (surrogate prey that was either live insects or seeds) to measure the effects of semi-natural habitats at field to landscape scales on levels of biological control in winter wheat in the UK. Sentinels were located in...

Data from: The ovipositor actuation mechanism of a parasitic wasp and its functional implications

Noraly M.M.E. Van Meer, Uroš Cerkvenik, Christian M. Schlepütz, Johan L. Van Leeuwen & Sander W. S. Gussekloo
Parasitic wasps use specialized needle-like structures­­—ovipositors—to drill in substrates to reach hidden hosts. The external ovipositor (terebra) consists of three interconnected, sliding elements (valvulae) which are moved reciprocally during insertion. This presumably reduces the required pushing force on the terebra and limits the risk of damage whilst probing. Although this is an important mechanism, it is still not completely understood how the actuation of the valvulae is achieved, and it has only been studied with...

Methodology matters for comparing coarse wood and bark decay rates across tree species

Chenhui Chang, Richard S.P Van Logtestijn, Leo Goudzwaard, Jurgen Van Hal, Juan Zuo, Mariet Hefting, Shanshan Yang, Frank J. Sterck, Lourens Poorter, Johannes H. C. Cornelissen & Ute Sass-Klaassen
1. The importance of wood decay for the global carbon and nutrient cycles is widely recognized. However, relatively little is known about bark decay dynamics, even though bark represents up to 25% of stem dry mass. Moreover, bark presence versus absence can significantly alter wood decay rates. Therefore, it really matters for the fate of carbon whether variation in bark and wood decay rates is coordinated across tree species. 2. Answering this question requires advances...

Data from: The origin of the legumes is a complex paleopolyploid phylogenomic tangle closely associated with the Cretaceous-Paleogene (K-Pg) mass extinction event

Erik Koenen, Dario Ojeda, Freek Bakker, Jan Wieringa, Catherine Kidner, Olivier Hardy, Toby Pennington, Patrick Herendeen, Anne Bruneau & Colin Hughes
The consequences of the Cretaceous-Paleogene (K-Pg) boundary (KPB) mass extinction for the evolution of plant diversity remain poorly understood, even though evolutionary turnover of plant lineages at the KPB is central to understanding assembly of the Cenozoic biota. The apparent concentration of whole genome duplication (WGD) events around the KPB may have played a role in survival and subsequent diversification of plant lineages. To gain new insights into the origins of Cenozoic biodiversity, we examine...

Lianas explore the forest canopy more effectively than trees under drier conditions

José A. Medina-Vega, Frans Bongers & Frank J. Sterck
Lianas rely on trees for support and access to high light positions in the forest canopy, but the implications for how lianas explore the canopy compared to trees remain understudied. We present an in situ forest canopy study to test the hypotheses that: (1) lianas favour leaf display over stem investment compared to trees and (2) lianas have greater potential to colonize non-shaded, high-light areas effectively than trees. We compared branches of 16 liana species...
