Elevated rates of positive selection drive the evolution of pestiferousness in the Colorado potato beetle ( Leptinotarsa decemlineata, Say)Zachary Cohen, Kristian Brevik, Yolanda H. Chen, David J. Hawthorne, Benjamin D. Weibel & Sean D. Schoville
In order to understand the evolution of pestiferousness, which we define as the accumulation of traits that contribute to an insect population’s success in an agroecosystem, we tested the importance of known genomic properties associated with rapid adaptation. Within the leaf beetle genus Leptinotarsa, only the Colorado potato beetle (CPB), Leptinotarsa decemlineata Say, and a few populations therein, has risen to pest status on cultivated nightshades, Solanum. Using whole genomes from ten closely related Leptinotarsa...
1. Ecologists have long been interested in linking individual behavior with higher-level processes. For motile species, this 'upscaling' is governed by how well any given movement strategy maximizes encounters with positive factors, and minimizes encounters with negative factors. Despite the importance of encounter events for a broad range of ecological processes, encounter theory has not kept pace with developments in animal tracking or movement modeling. Furthermore, existing work has focused primarily on the relationship between...
This dataset includes absorbance and fluourescence spectra used to compare the sensitivity of dissolved organic matter to experimental photodegradation. Spectra represent time series of measurements collected during 20-hour lab photodegradations. Nearly all experiments consisted of 60 absorbance and fluorescence measurements collected every 20 minutes as samples were exposed to simulated sunlight. A subset of these data were used to fit a parallel factor analysis (PARAFAC) model, onto which the entire data set was projected. Each...
Site-specific impacts of a major hurricane on alpha and beta diversity in tropical forest seedling communitiesSamantha Worthy, Vanessa Rubio, Kirstin Staiger, Boris Ngouajio, Jie Yang & Nathan Swenson
Large scale disturbances are known to impact the alpha and beta diversity of communities. However, whether these disturbances increase or decrease diversity is often debated. The goal of this study was to quantify how the diversity of the seedling community was impacted within and across elevation in the El Yunque forest of Puerto Rico following a major hurricane. We tested two alternative hypotheses, that hurricanes are relatively more homogenizing or non-homogenizing forces, by quantifying changes...

Plant–insect associations have been a significant component of terrestrial ecology for over 400 million years. Exploring these interactions in the fossil record, through novel perspectives, provides a window into understanding evolutionary and ecological forces that shaped these interactions. For the past several decades, researchers have documented, described and categorized fossil evidence of these interactions. Drawing on powerful tools from network science, we propose here a bipartite network representation of fossilized plants and their herbivore-induced leaf...
Differential effects of nematode infection on pollinating and non-pollinating fig wasps: can shared antagonism provide net benefits to a mutualism?Justin Van Goor, Finn Piatscheck, Derek Houston & John Nason
1. Species pairs that form mutualistic associations are also components of broader organismal community networks. These network-level associations have shaped the evolution of individual mutualisms through interspecific interactions ranging from secondarily mutualistic to intensely antagonistic. Our understanding of this complex context remains limited because characterizing the impacts of species interacting with focal mutualists is often difficult. How is the fitness of mutualists impacted by the co-occurring interactive network of community associates? 2. We investigate this...
