Data from: The influence of host plant extrafloral nectaries on multitrophic interactions: an experimental investigationSuzanne Koptur, Ian M. Jones & Jorge E. Peña
A field experiment was conducted with outplantings of the native perennial shrub Senna mexicana var. chapmanii in a semi-natural area adjacent to native pine rockland habitat in southern Florida. The presence of ants and the availability of extrafloral nectar were manipulated in a stratified random design. Insect communities were monitored and recorded over a period of six months with a view to addressing three main questions. Do ants provide biotic defense against key herbivores on...
Data from: Globally, functional traits are weak predictors of juvenile tree growth, and we do not know whyC. E. Timothy Paine, Lucy Amissah, Harald Auge, Christopher Baraloto, Martin Baruffol, Nils Bourland, Helge Bruelheide, Kasso Daïnou, Roland C. De Gouvenain, Jean-Louis Doucet, Susan Doust, Paul V. A.

Holl, Hervé Jactel, Xuefei Li, Kaoru Kitajima, Julia Koricheva, Cristina Martínez-Garza, Christian Messier, Alain Paquette, Christopher Philipson, Daniel Piotto, Lourens Poorter … & Andy Hector
1. Plant functional traits, in particular specific leaf area (SLA), wood density and seed mass, are often good predictors of individual tree growth rates within communities. Individuals and species with high SLA, low wood density and small seeds tend to have faster growth rates. 2. If community-level relationships between traits and growth have general predictive value, then similar relationships should also be observed in analyses that integrate across taxa, biogeographic regions and environments. Such global...
Data from: Distributions of irritative zones are related to individual alterations of resting-state networks in focal epilepsyYinchen Song, Basavaraju G. Sanganahalli, Fahmeed Hyder, Wei-Chiang Lin & Jorge J. Riera
Alterations in the connectivity patterns of the fMRI-based resting-state networks (RSNs) have been reported in several types of epilepsies. Evidence pointed out these alterations might be associated with the genesis and propagation of interictal epileptiform discharges (IEDs). IEDs also evoke blood-oxygen-level dependent (BOLD) responses, which have been used to delineate irritative zones during preoperative work-up. Therefore, one may expect a relationship between the topology of the IED-evoked BOLD response network and the altered spatial patterns...
Data from: Predation risk, resource quality, and reef structural complexity shape territoriality in a coral reef herbivoreLaura B. Catano, Bridgette K. Gunn, Megan C. Kelley & Deron E. Burkepile
For many species securing territories is important for feeding and reproduction. Factors such as competition, habitat availability, and male characteristics can influence an individual’s ability to establish and maintain a territory. The risk of predation can have an important influence on feeding and reproduction; however, few have studied its effect on territoriality. We investigated territoriality in a haremic, polygynous species of coral reef herbivore, Sparisoma aurofrenatum (redband parrotfish), across eight reefs in the Florida Keys...
Data from: Anthropogenic ecosystem fragmentation drives shared and unique patterns of sexual signal divergence among three species of Bahamian mosquitofishSean T. Giery, Craig A. Layman & R. Brian Langerhans
When confronted with similar environmental challenges, different organisms can exhibit dissimilar phenotypic responses. Therefore, understanding patterns of phenotypic divergence for closely related species requires considering distinct evolutionary histories. Here, we investigated how a common form of human-induced environmental alteration, habitat fragmentation, may drive phenotypic divergence among three closely related species of Bahamian mosquitofish (Gambusia spp.). Focusing on one phenotypic trait (male coloration), having a priori predictions of divergence, we tested whether populations persisting in fragmented...
Data from: Taxonomic and functional composition of arthropod assemblages across contrasting Amazonian forestsP. A. Greg Lamarre, Bruno Hérault, Paul V. A. Fine, Vincent Vedel, Roland Lupoli, Italo Mesones, Christopher Baraloto & Greg P. A. Lamarre
Arthropods represent most of global biodiversity, with the highest diversity found in tropical rainforests. Nevertheless, we have a very incomplete understanding of how tropical arthropod communities are assembled. We conducted a comprehensive mass-sampling of arthropod communities within three major habitat types of lowland Amazonian rainforest, including terra firme clay, white-sand, and seasonally-flooded forests in Peru and French Guiana. We examined how taxonomic and functional composition (at the family level) differed across these habitat types in...
Data from: Reefscapes of fear: predation risk and reef heterogeneity interact to shape herbivore foraging behaviorLaura B. Catano, Maria C. Rojas, Ryan J. Malossi, Joseph R. Peters, Michael R. Heithaus, James W. Fourqurean & Deron E. Burkepile
Predators can exert strong direct and indirect effects on ecological communities by intimidating their prey. The nature of predation risk effects is often context dependent, but in some ecosystems these contingencies are often overlooked. Risk effects are often not uniform across landscapes or among species. Indeed, they can vary widely across gradients of habitat complexity and with different prey escape tactics. These context-dependencies may be especially important for ecosystems such as coral reefs that vary...
Data from: Quantity over quality: light intensity, but not red/far-red ratio, affects extrafloral nectar production in Senna mexicana var. chapmaniiIan M. Jones & Suzanne Koptur
Extrafloral nectar (EFN) mediates food-for-protection mutualisms between plants and insects and provides plants with a form of indirect defense against herbivory. Understanding sources of variation in EFN production is important because such variations affect the number and identity of insect visitors and the effectiveness of plant defense. Light represents a potentially crucial tool for regulating resource allocation to defense, as it not only contributes energy but may help plants to anticipate future conditions. Low red/far-red...
