Silliman, Johan Van De Koppel, Matthijs Van Der Geest, Jan A. Van Gils, Henk W. Van Der Veer, Theunis Piersma, Peter C. De Ruiter, Han Olff & Tjisse Van Der Heide
The diversity and structure of ecosystems has been found to depend both on trophic interactions in food webs and on other species interactions such as habitat modification and mutualism that form non-trophic interaction networks. However, quantification of the dependencies between these two main interaction networks has remained elusive. In this study, we assessed how habitat-modifying organisms affect basic food web properties by conducting in-depth empirical investigations of two ecosystems: North American temperate fringing marshes and...

Data from: Plant traits and plant biogeography control the biotic resistance provided by generalist herbivores

Bart M. C. Grutters, Yvonne O. A. Roijendijk, Wilco C. E. P. Verberk & Elisabeth S. Bakker
Globalization and climate change trigger species invasions and range shifts, which reshuffle communities at an exceptional rate and expose plant migrants to unfamiliar herbivores. Dominant hypotheses to predict plant success are based on evolutionary novelty: either herbivores are maladapted to consume novel plants (enemy release hypothesis), or novel plants are maladapted to deter herbivores (biotic resistance hypothesis). Since novelty can work both ways, it fails to consistently predict when herbivores will consume novel over non-novel...

Data from: Effects of multi-generational stress exposure and offspring environment on the expression and persistence of transgenerational effects in Arabidopsis thaliana

Maartje P. Groot, Rik Kooke, Nieke Knoben, Philippine Vergeer, Joost J. B. Keurentjes, N. Joop Ouborg, Koen Verhoeven & Koen J. F. Verhoeven
Plant phenotypes can be affected by environments experienced by their parents. Parental environmental effects are reported for the first offspring generation and some studies showed persisting environmental effects in second and further offspring generations. However, the expression of these transgenerational effects proved context-dependent and their reproducibility can be low. Here we study the context-dependency of transgenerational effects by evaluating parental and transgenerational effects under a range of parental induction and offspring evaluation conditions. We systematically...

Data from: The impact of hotspot-targeted interventions on malaria transmission in Rachuonyo south district in the western Kenyan highlands: a cluster-randomized controlled trial

Teun Bousema, Gillian Stresman, Amrish Y. Baidjoe, John Bradley, Philip Knight, William Stone, Victor Osoti, Euniah Makori, Chrispin Owaga, Wycliffe Odongo, Pauline China, Shehu Shagari, Ogobara K. Doumbo, Robert W. Sauerwein, Simon Kariuki, Chris Drakeley, Jennifer Stevenson & Jonathan Cox
Background: Malaria transmission is highly heterogeneous, generating malaria hotspots that can fuel malaria transmission across a wider area. Targeting hotspots may represent an efficacious strategy for reducing malaria transmission. We determined the impact of interventions targeted to serologically defined malaria hotspots on malaria transmission both inside hotspots and in surrounding communities. Methods and Findings: Twenty-seven serologically defined malaria hotspots were detected in a survey conducted from 24 June to 31 July 2011 that included 17,503...

Data from: The simultaneous inducibility of phytochemicals related to plant direct and indirect defences against herbivores is stronger at low elevation

Loïc Pellissier, Xoaquín Moreira, Holger Danner, Martha Serrano, Nicolas Salamin, Nicole M. Van Dam & Sergio Rasmann
Ecological theory indicates that warmer and more stable climates should result in stronger biotic interactions. Therefore, plant species growing at lower elevations and experiencing greater herbivore pressure, should invest in higher levels of defences than those at higher elevations. Nonetheless, there are a number of studies that have found no effect of elevational gradients on plant defensive traits. Several factors might explain the lack of consistency for the altitude-defence relationships; including 1) the reduction of...

Data from: Recent and dynamic transposable elements contribute to genomic divergence under asexuality

Julie Ferreira De Carvalho, Victor De Jager, Thomas P. Van Gurp, Niels C.A.M. Wagemaker & Koen J.F. Verhoeven
Background: Transposable elements (TEs) are mobile pieces of genetic information with high mutagenic potential for the host genome. Transposition is often neutral or deleterious but may also generate potentially adaptive genetic variation. This additional source of variation could be especially relevant in non-recombining species reproducing asexually. However, evidence is lacking to determine the relevance of TEs in plant asexual genome evolution and their associated effects. Here, we characterize the repetitive fraction of the genome of...

Data from: A keystone mutualism underpins resilience of a coastal ecosystem to drought

Christine Angelini, John N. Griffin, Johan Van De Koppel, Leon P. M. Lamers, Alfons J. P. Smolders, Marlous Derksen-Hooijberg, Tjisse Van Der Heide & Brian R. Silliman
Droughts are increasing in severity and frequency, yet the mechanisms that strengthen ecosystem resilience to this stress remain poorly understood. Here, we test whether positive interactions in the form of a mutualism between mussels and dominant cordgrass in salt marshes enhance ecosystem resistance to and recovery from drought. Surveys spanning 250 km of southeastern US coastline reveal spatially dispersed mussel mounds increased cordgrass survival during severe drought by 5- to 25-times. Surveys and mussel addition...

Data from: Consensus forecasting of intertidal seagrass habitat in the Wadden Sea

Eelke O. Folmer, Justus E. E. Van Beusekom, Tobias Dolch, Ulf Gräwe, Marieke M. Van Katwijk, Kerstin Kolbe, Catharina J. M. Philippart & Catharina J.M. Philippart
After the dramatic eutrophication-induced decline of intertidal seagrasses in the 1970s, the Wadden Sea has shown diverging developments. In the northern Wadden Sea, seagrass beds have expanded and become denser, while in the southern Wadden Sea, only small beds with low shoot densities are found. A lack of documentation of historical distributions hampers conservation management. Yet, the recovery in the northern Wadden Sea provides opportunity to construct robust habitat suitability models to support management. We...

Data from: Marine Phytophthora species can hamper conservation and restoration of vegetated coastal ecosystems

Laura L. Govers, , Johan P. Meffert, Tjeerd J. Bouma, Patricia C.J. Van Rijswick, Jannes H. T. Heusinkveld, Robert J. Orth, Marieke M. Van Katwijk & Tjisse Van Der Heide
Phytophthora species are potent pathogens that can devastate terrestrial plants, causing billions of dollars of damage yearly to agricultural crops and harming fragile ecosystems worldwide. Yet, virtually nothing is known about the distribution and pathogenicity of their marine relatives. This is surprising, as marine plants form vital habitats in coastal zones worldwide (i.e. mangrove forests, salt marshes, seagrass beds), and disease may be an important bottleneck for the conservation and restoration of these rapidly declining...

Data from: Hydrologically contrasting environments induce genetic but not phenotypic differentiation in Solanum dulcamara

Qian Zhang, Janny L. Peeters, Eric J. W. Visser, Hans De Kroon, Heidrun Huber & Janny L. Peters
In contrasting habitats, locally adapted populations are expected to evolve through directional selection. Hydrological gradients provide a scenario where strong selection forces have led to species segregation in communities along the hydrological niche axes due to specific adaptations to their ambient environment. However, much less is known about the processes enabling species with wide ecological amplitudes, such as Solanum dulcamara L., to occupy the contrasting niches at the far ends of the gradient. Here, we...
