Data from: Larger plants promote a greater diversity of symbiotic nitrogen-fixing soil bacteria associated with an Australian endemic legume

Russell Dinnage, Anna K. Simonsen, Luke G. Barrett, Marcel Cardillo, Nat Raisbeck-Brown, Peter H. Thrall & Suzanne M. Prober
A major goal in microbial ecology is to understand the factors that structure bacterial communities across space and time. For microbes that are plant symbionts, community assembly processes can lead to either a positive or negative relationship between plant size or age and soil microbe diversity. Here, we evaluated the extent to which such relationships exist within a single legume species (Acacia acuminata) and their naturally occurring symbiotic nitrogen-fixing bacteria (rhizobia). 2. We quantified the...

Data from: SNP markers tightly linked to root knot nematode resistance in grapevine (Vitis cinerea) identified by a genotyping-by-sequencing approach followed by Sequenom MassARRAY validation

Harley M. Smith, Brady P. Smith, Norma B. Morales, Sam Moskwa, Peter R. Clingeleffer & Mark R. Thomas
Plant parasitic nematodes, including root knot nematode Meloidogyne species, cause extensive damage to agriculture and horticultural crops. As Vitis vinifera cultivars are susceptible to root knot nematode parasitism, rootstocks resistant to these soils pests provide a sustainable approach to maintain grapevine production. Currently, most of the commercially available root knot nematode resistant rootstocks are highly vigorous and take up excess potassium, which reduces wine quality. As a result, there is a pressing need to breed...

Data from: Experimental habitat fragmentation disrupts nematode infections in Australian skinks

Julian Resasco, Matthew E. Bitters, Saul A. Cunningham, Hugh I. Jones, Valerie J. McKenzie & Kendi F. Davies
Habitat conversion and fragmentation threaten biodiversity and disrupt species interactions. While parasites are recognized as ecologically important, the impacts of fragmentation on parasitism are poorly understood relative to other species interactions. This lack of understanding is in part due to confounding landscape factors that accompany fragmentation. Fragmentation experiments provide the opportunity to fill this knowledge gap by mechanistically testing how fragmentation affects parasitism while controlling landscape factors. In a large-scale, long-term experiment, we asked how...

Data from: Optimal soil carbon sampling designs to achieve cost-effectiveness: a case study in blue carbon ecosystems

Mary A. Young, Peter I. Macreadie, Clare Duncan, Paul E. Carnell, Emily Nicholson, Oscar Serrano, Carlos M. Duarte, Glenn Shiell, Jeff Baldock & Daniel Ierodiaconou
Researchers are increasingly studying carbon (C) storage by natural ecosystems for climate mitigation, including coastal ‘blue carbon’ ecosystems. Unfortunately, little guidance on how to achieve robust, cost-effective estimates of blue C stocks to inform inventories exists. We use existing data (492 cores) to develop recommendations on the sampling effort required to achieve robust estimates of blue C. Using a broad-scale, spatially explicit dataset from Victoria, Australia, we applied multiple spatial methods to provide guidelines for...

Data from: When to monitor and when to act: value of information theory for multiple management units and limited budgets

Joseph R. Bennett, Sean L. Maxwell, Amanda E. Martin, Iadine Chadès, Lenore Fahrig & Benjamin Gilbert
1.The question of when to monitor and when to act is fundamental to applied ecology, and notoriously difficult to answer. Value of information (VOI) theory holds great promise to help answer this question for many management problems. However, VOI theory in applied ecology has only been demonstrated in single-decision problems, and has lacked explicit links between monitoring and management costs. 2.Here, we present an extension of VOI theory for solving multi-unit decisions of whether to...

Data from: Leaf nutrients, not specific leaf area, are consistent indicators of elevated nutrient inputs

Jennifer Firn, James M. McGree, Eric Harvey, Habacuc Flores-Moreno, Martin Schütz, Yvonne M. Buckley, Elizabeth T. Borer, Eric W. Seabloom, Kimberly J. La Pierre, Andrew M. MacDougall, Suzanne M. Prober, Carly J. Stevens, Lauren L. Sullivan, Erica Porter, Emma Ladouceur, Charlotte Allen, Karine H. Moromizato, John W. Morgan, W. Stanley Harpole, Yann Hautier, Nico Eisenhauer, Justin P. Wright, Peter B. Adler, Carlos Alberto Arnillas, Jonathan D. Bakker … & Anita C. Risch
Leaf traits are frequently measured in ecology to provide a ‘common currency’ for predicting how anthropogenic pressures impact ecosystem function. Here, we test whether leaf traits consistently respond to experimental treatments across 27 globally distributed grassland sites across 4 continents. We find that specific leaf area (leaf area per unit mass)—a commonly measured morphological trait inferring shifts between plant growth strategies—did not respond to up to four years of soil nutrient additions. Leaf nitrogen, phosphorus...

Data from: Does prey encounter and nutrient content affect prey selection in wolf spiders inhabiting Bt cotton fields?

Dalila Rendon, Phillip W. Taylor, Shawn M. Wilder & Mary E.A. Whitehouse
Wolf spiders are abundant and voracious predators at the soil-plant interface in cotton crops. Among other prey, they attack late-instar larvae of the cotton bollworm Helicoverpa spp., an economically important pest. Consequently, wolf spiders in transgenic Bt cotton could provide significant biological control of Bt-resistant Helicoverpa larvae that descend to the soil to pupate. The predator-prey interactions between wolf spiders and Helicoverpa could, however, be constrained by the presence of alternative prey and intraguild predators....

Data from: Gigapixel big data movies provide cost‐effective seascape scale direct measurements of open‐access coastal human use such as recreational fisheries

David J. H. Flynn, Tim P. Lynch, Neville S. Barrett, Lincoln S. C. Wong, Carlie Devine & David Hughes
Collecting data on unlicensed open‐access coastal activities, such as some types of recreational fishing, has often relied on telephone interviews selected from landline directories. However, this approach is becoming obsolete due to changes in communication technology such as a switch to unlisted mobile phones. Other methods, such as boat ramp interviews, are often impractical due to high labor cost. We trialed an autonomous, ultra‐high‐resolution photosampling method as a cost effect solution for direct measurements of...

Data from: Predicting the effects of parasite co-infection across species boundaries

Joanne Lello, Susan J. McClure, Kerri Tyrrell & Mark E. Viney
It is normal for hosts to be coinfected by parasites. Interactions among coinfecting species can have profound consequences, including changing parasite transmission dynamics, altering disease severity, and confounding attempts at parasite control. Despite the importance of coinfection, there is currently no way to predict how different parasite species may interact with one another, nor the consequences of those interactions. Here we demonstrate a method that enables such prediction by identifying two nematode parasite groups based...

Data from: A novel approach to determining dynamic nitrogen thresholds for seagrass conservation

Milena B. Fernandes, Jos Van Gils, Paul L. A. Erftemeijer, Rob Daly, Dennis Gonzalez & Karen Rouse
1. Seagrass decline is often related to eutrophication, with sudden and drastic losses attributed to tipping points in nutrient loads. The identification of these threshold loads is an important step in the sustainable management of nutrient discharges. 2. In this study, a novel methodological approach is presented to simulate the spatial and temporal dynamics of coastal nitrogen loads, and its relationship to seagrass loss. The analysis allows the identification of nitrogen thresholds associated with the...
