Data from: Mismatches between the resources for adult herbivores and their offspring suggest invasive Spartina alterniflora is an ecological trap

Ke-Ke Sun, Wen-Sheng Yu, Jia-Jia Jiang, Christina Richards, Evan Siemann, Jun Ma, Bo Li & Rui-Ting Ju
1. Plant invasions can alter the behavior and performance of native herbivorous insects because the insects are evolutionarily naïve to the novel plants. An ecological trap results when native insects prefer invasive plants over their native hosts but suffer reduced fitness on the invaders. Although such traps are predicted to occur frequently given the prevalence of invasive plants, empirical support for ecological traps and their underlying mechanisms remains sparse. 2. We examined the potential for...

Data from: Pooled analysis suggests benefit of catheter-based hematoma removal for intracerebral hemorrhage

Pitchaiah Mandava, Santosh B. Murthy, Neel Shah, Yves Samson, Marek Kimmel & Thomas A. Kent
Objective: To develop models of outcome for intracerebral hemorrhage (ICH) to identify promising and futile interventions based on their early phase results without need for correction for baseline imbalances. Methods: We developed a pooled outcome model from the control arms of randomized control trials and tested different interventions against the model at comparable baseline conditions. Eligible clinical trials and large case series were identified from multiple library databases. Models based on baseline factors reported in...

Data from: Biogeographic variation of distance-dependent effects in an invasive tree species

Qiang Yang, Jianqing Ding & Evan Siemann
1.Plant pathogens and herbivores can maintain forest diversity by reducing survival of tree seedlings close to conspecifics. However, how biogeographic variation in these natural enemies affects such distance‐dependent processes is unknown. Because invasive plants escape ecologically important enemies when introduced to a new range, distance‐dependent mortality may differ between their native and introduced ranges. 2. Here, we test whether the invasive tree Triadica sebifera escaped distance‐dependent mortality when introduced to the US from China, and...

Data from: Shifts in phenological mean and synchrony interact to shape competitive outcomes

Shannon K. Carter & Volker H. Rudolf
Climate change-induced phenological shifts are ubiquitous and have the potential to disrupt natural communities by changing the timing of species interactions. Shifts in first and/or mean phenological date are well documented, but recent studies indicate that shifts in synchrony (individual variation around these metrics) can be just as common. However, we know little about how both types of phenological shifts interact to affect species interactions and natural communities. Here, we experimentally manipulated the hatching phenologies...

Data from: Root feeding larvae increase their performance by inducing leaf volatiles that attract aboveground conspecific adults

Xiao Sun, Evan Siemann, Zhen Liu, Qiyun Wang, Dingli Wang, Wei Huang, Chujun Zhang & Jianqing Ding
1.Herbivore‐induced changes in plant volatile emissions mediate above‐belowground interactions by determining host plant colonization of different herbivores. By changing shoot‐emitted volatiles, belowground herbivores may use the plant to extend their capacity to interact with aboveground con‐ and heterospecifics. 2.We investigated the attractiveness of Triadica sebifera plants infested by larvae of a specialist beetle or root‐knot nematodes to aboveground herbivores. We then determined the contribution of leaf volatiles to the observed recruitment patterns using olfactometer experiments....

A multivariate approach reveals diversity of ontogenetic niche shifts across taxonomic and functional groups

Volker Rudolf
Shifts in the fundamental and realize niche of individuals during their ontogeny are ubiquitous in nature, but we know little about what aspects of the niche change and how these changes vary across species within communities. Yet, this knowledge is essential to predict the dynamics of populations and communities and how they respond to environmental change. Here I introduce a range of metrics to describe different aspects of shifts in the realized trophic niche of...

Strong and weak cross-sex correlations govern the quantitative-genetic architecture of social group choice in Drosophila melanogaster

Julia Saltz
When genotypes differ in niche-constructing traits, genotypes are expected to differ in which environments they experience, providing a novel causal relationship between genotypes, environments, and behavior. Such genetic variation in niche construction (or, more precisely, environment construction) is predicted to be especially important for social environments, yet the quantitative-genetic parameters governing such variation is still poorly understood. Here, we examine genetic variation and cross-sex genetic correlations for social environment-constructing behaviors. We focus on whether genetic...

Sex‐differences in disease avoidance behavior vary across modes of pathogen exposure

Carl N. Keiser, Volker H.W. Rudolf, Matthew C. Luksik & Julia B. Saltz
Sex‐differences in disease susceptibility are widespread, and these disparities are often compounded in cases where sexual dimorphism increases exposure risk to parasites for one sex more than the other. Studies rarely link sex‐differences in disease susceptibility to sex‐differences in infection avoidance behavior. Yet, understanding the intersection of hosts’ susceptibility to infection and infection avoidance behavior is essential to predicting infection risk variation. Here, we use the fruit fly Drosophila melanogaster and a generalist entomopathogenic fungus,...

Data from: Cascading reproductive isolation: plant phenology drives temporal isolation among populations of a host-specific herbivore

Glen R. Hood, Linyi Zhang, Elaine G. Hu, James R. Ott & Scott P. Egan
All organisms exist within a complex network of interacting species, thus evolutionary change may have reciprocal effects on multiple taxa. Here, we demonstrate “cascading reproductive isolation,” whereby ecological differences that reduce gene flow between populations at one trophic level affect reproductive isolation (RI) among interacting species at the next trophic level. Using a combination of field, laboratory and common-garden studies and long-term herbaria records, we estimate and evaluate the relative contribution of temporal RI to...

Data from: Reproductive losses due to climate change-induced earlier flowering are not the primary threat to plant population viability in a perennial herb

Amy M. Iler, Aldo Compagnoni, David W. Inouye, Jennifer L. Williams, Paul J. CaraDonna, Aaron Anderson & Tom E.X. Miller
1. Despite a global footprint of shifts in flowering phenology in response to climate change, the reproductive consequences of these shifts are poorly understood. Furthermore, it is unknown whether altered flowering times affect plant population viability. 2. We examine whether climate change-induced earlier flowering has consequences for population persistence by incorporating reproductive losses from frost damage (a risk of early flowering) in population models of a subalpine sunflower (Helianthella quinquenervis). Using long-term demographic data for...

Data from: Thermal plasticity of a freshwater cnidarian holobiont: detection of trans-generational effects in asexually reproducing hosts and symbionts

Siao Ye, Krishna N. Badhiwala, Jacob T. Robinson, Won Hee Cho & Evan Siemann
Understanding factors affecting the susceptibility of organisms to thermal stress is of enormous interest in light of our rapidly changing climate. When adaptation is limited, thermal acclimation and deacclimation abilities of organisms are critical for population persistence through a period of thermal stress. Holobionts (hosts plus associated symbionts) are key components of various ecosystems, such as coral reefs, yet the contributions of their two partners to holobiont thermal plasticity are poorly understood. Here, we tested...

Temporal isolation between sympatric host plants cascades across multiple trophic levels of host-associated insects

Linyi Zhang, Glen Hood, James Ott & Scott Egan
Phenological differences between host plants can promote temporal isolation among host-associated populations of insects with life cycles tightly coupled to plant phenology. Divergence in the timing of spring budbreak between two sympatric sister oak species has been shown to promote temporal isolation between host plants and their host-associated populations of a cynipid gall wasp. Here we examined the generality of this mechanism by testing the hypothesis of cascading temporal isolation for five additional gall-formers and...
