Analyzing time-energy constraints to understand the links between environmental change and local extinctions in terrestrial ectotherms

Casey Brewster, Matthew Gifford, Jason Ortega & Steven Beaupre
Accelerated extinction rates have prompted an increased focus on the interplay between environmental change and species response. The effects of environmental change on thermal opportunity are typically considered through a climate change context. However, habitat alteration can also have strong effects on the thermal environment. Additionally, habitat alteration is considered a leading factor of species extinction, yet few studies address the influence of habitat alteration on thermal opportunity and time-energy budgets in at-risk species. Here...

Data from: A literature synthesis resolves litter intrinsic constraints on fungal dynamics and decomposition across standing dead macrophytes

Tori Hebert, Halvor Halvorson & Kevin Kuehn
The standing dead phase is an important stage in the decomposition of emergent vegetation in marsh wetlands, yet few studies have examined how intrinsic litter traits constrain rates of standing litter decomposition or fungal colonization across plant tissue types or species. To address broad constraints on the decomposition of standing dead litter, we conducted a systematic survey of emergent standing dead decomposition studies that measured decay rates and/or fungal biomass, and litter % lignin, carbon:nitrogen...

Data from: The specificity of Burkholderia symbionts in the social amoeba farming symbiosis: prevalence, species, genetic and phenotypic diversity

Tamara S. Haselkorn, Susanne DiSalvo, Jacob W. Miller, Usman Bashir, Debra A. Brock, David C. Queller & Joan E. Strassmann
The establishment of symbioses between eukaryotic hosts and bacterial symbionts in nature is a dynamic process. The formation of such relationships depends on the life history of both partners. Bacterial symbionts of amoebae may have unique evolutionary trajectories to the symbiont lifestyle, because bacteria are typically ingested as prey. To persist after being eaten, bacteria must survive phagocytosis. In the social amoeba Dictyostelium discoideum, certain strains of Burkholderia bacteria are able to resist amoebal digestion...

Data from: Detrital nutrient content and leaf species differentially affect growth and nutritional regulation of detritivores

Halvor M. Halvorson, Chris L. Fuller, Sally A. Entrekin, J. Thad Scott & Michelle A. Evans-White
Resource nutrient content and identity are common bottom-up controls on organismal growth and nutritional regulation. One framework to study these factors, ecological stoichiometry theory, predicts that elevated resource nitrogen (N) and phosphorus (P) contents enhance organism growth by alleviating constraints on N and P acquisition. However, the regulatory mechanisms underlying this response – including whether responses depend on resource identity – remain poorly understood. In this study, we tested roles of detrital N and P...
