1. Soil microbial communities are essential in regulating ecosystem functions and services. However, the importance of bacterial and fungal communities as predictors of multiple soil functions (i.e., soil multifunctionality) in grassland ecosystems has not been studied systematically. 2. Here, we measured soil microbial diversity, community composition, biomass, and multiple soil functions of 41 sites in five grassland ecosystems spanning a 3,500 km northeast–southwest transect. The random forest algorithm was adopted to determine the importance of...

Abstract Background More people with rare diseases likely receive disease education and emotional and practical support from peer-led support groups than any other way. Most rare-disease support groups are delivered outside of the health care system by untrained leaders. Potential benefits may not be achieved and harms, such as dissemination of inaccurate information, may occur. Our primary objective was to evaluate the effects of a rare-disease support group leader education program, which was developed collaboratively...

Diversity and distribution of tropical ectomycorrhizal fungi

Adriana Corrales, Rachel A. Koch, Aída M. Vasco-Palacios, Matthew E. Smith, Zai-Wei Ge & Terry W. Henkel
The tropics were long considered to have few ectomycorrhizal fungi, presumably due to a paucity of ectomycorrhizal host plants relative to higher-latitude ecosystems. However, an increase in research in tropical regions over the past 30 years has greatly expanded knowledge about the occurrence of tropical ectomycorrhizal fungi. To assess their broad biogeographic and diversity patterns, we conducted a comprehensive review and quantitative data analysis of 49 studies with 80 individual data sets along with additional...

Mapping soil microbial residence time at the global scale

Fazhu Zhao, Liyuan He, Bond-Lamberty Ben, Janssens Ivan, Jieying Wang, Guowei Pang, Yuwei Wu & Xiaofeng Xu
Soil microbes ultimately drive the mineralization of soil organic carbon and thus ecosystem functions. We compiled a dataset of the seasonality of microbial biomass carbon (MBC) and developed a semi-mechanistic model to map monthly MBC across the globe. MBC exhibits an equatorially symmetric seasonality between the Northern and Southern Hemispheres. In the Northern Hemisphere, MBC peaks in autumn and is minimal in spring at low latitudes (<25° N), peaks in the spring and is minimal...

Using landscape genomics to delineate future adaptive potential for climate change in the Yosemite Toad (Anaxyrus canorus)

Paul Maier, Amy Vandergast & Andrew Bohonak
An essential goal in conservation biology is delineating population units that maximize the probability of species persisting into the future and adapting to future environmental change. However, future-facing conservation concerns are often addressed using retrospective patterns that could be irrelevant. We recommend a novel landscape genomics framework for delineating future “Geminate Evolutionary Units” (GEUs) in a focal species: (1) identify loci under environmental selection, (2) model and map adaptive conservation units that may spawn future...

Phenotypic and ecological data from: Widespread convergent morphological evolution within the largest family of songbirds

Amelia-Juliette Demery & Kevin Burns
Although convergence is a common evolutionary phenomenon, few studies have quantified its prevalence across a large, densely sampled clade. Large-scale phylogenies and the advent of novel computational methods facilitate more robust identification of convergent events and their statistical significance. The tanagers (Aves: Thraupidae), the largest family of songbirds, offer an excellent opportunity to study the extent of phenotypic convergence in response to similar ecological pressures on a continental scale. To investigate convergence in the group,...

Temporal changes in predator density are linked to shifts in prey behavior, mortality, and abundance in the field

Shelby Rinehart, Xavius Boone, Jessica Patzlaff, Stephen Schroete & Jeremy Long
Predators suppress prey populations and elicit defensive phenotypes in prey. The magnitude of predator effects depends upon several factors, including the density of predators, and their cue concentrations, in the environment. Predator density manipulations have often relied on laboratory studies that use unrealistic densities of predators and prey over unnatural temporal and spatial scales. Field studies can provide insights into predator-prey interactions under more realistic scenarios. However, field studies linking predator density and prey populations...
