Data from: Adult dietary protein has age- and context-dependent effects on male post-copulatory performanceErin L. Macartney, Angela J. Crean & R. Bonduriansky
The highly-conserved effect of dietary protein restriction on life-span and ageing is observed in both sexes and across a vast range of taxa. This extension of life-span is frequently accompanied by a reduction in female fecundity and it has been hypothesised that individuals may reallocate resources away from reproduction and into somatic maintenance. However, effects of dietary protein restriction on male reproduction are less consistent, suggesting that these effects may depend on other environmental parameters....

Significant progress has been made in characterizing broadly neutralizing antibodies against the HIV envelope glycoprotein Env, but an effective vaccine has proven elusive. Vaccine development would be facilitated if common features of early founder virus required for transmission could be identified. Here we employ a combination of bioinformatic and operations research methods to determine the most prevalent features that distinguish 78 subtype B and 55 subtype C founder Env sequences from an equal number of...
Data from: Sex-dependent expression of behavioural genetic architectures and the evolution of sexual dimorphismChang S. Han & Niels J. Dingemanse
Empirical studies imply that sex-specific genetic architectures can resolve evolutionary conflicts between males and females, and thereby facilitate the evolution of sexual dimorphism. Sex-specificity of behavioural genetic architectures have, however, rarely been considered. Moreover, as the expression of genetic (co)variances is often environment-dependent, general inferences on sex-specific genetic architectures require estimates of quantitative genetics parameters under multiple conditions. We measured exploration and aggression in pedigreed populations of southern field crickets (Gryllus bimaculatus) raised on either...
Data from: Livestock activity increases exotic plant richness, but wildlife increases native richness, with stronger effects under low productivityDavid J. Eldridge, Manuel Delgado-Baquerizo, Samantha K. Travers, James Val, Ian Oliver, Josh W. Dorrough & Santiago Soliveres
1.Grazing by domestic livestock is one of the most widespread land uses worldwide, particularly in rangelands, where it co-occurs with grazing by wild herbivores. Grazing effects on plant diversity are likely to depend on intensity of grazing, herbivore type, coevolution with plants and prevailing environmental conditions. 2.We collected data on climate, plant productivity, soil properties, grazing intensity and herbivore type; and measured their effects on plant species richness from 451 sites across 0.4 M km2...
1. Rewilding is a strategy for ecological restoration that uses reintroductions of animals to re-establish the ecological functions of keystone species. Globally, rewilding efforts have focused primarily on reinstating the ecological functions of charismatic megafauna. In Australia, rewilding efforts have focused on restoring the ecological functions of herbivorous and omnivorous rodents and marsupials weighing between 30-5000g inside of predator-proof exclosures. 2. In many arid ecosystems, mammals are considered the dominant seed predators. In Australian deserts,...
Data from: Landscape context explains changes in the functional diversity of regenerating forests better than climate or species richnessMichael Sams, Hao Ran Lai, Stephen Bonser, Peter Vesk, Robert Kooyman, Daniel Metcalfe, John W. Morgan, Margaret Mayfield, M. A. Sams, D. J. Metcalfe, R. M. Kooyman & P. A. Vesk
Aim A rich literature on forest succession provides general expectations for the steps forests go through while reassembling after disturbance, yet we still have a surprisingly poor understanding of why the outcomes of forest recovery after logging (or other disturbances) vary so extensively. In this paper, we test the hypothesis that regional species pool, system productivity, climate and landscape structure are important drivers of forest reassembly outcomes. Location Transect 1,500 km in length along the...
The attached dataset was used for the analysis presented in: Validation of participant eligibility for pre-exposure prophylaxis: Baseline data from the PRELUDE Demonstration Project. It contains the relevant baseline data from the PrELUDE study, including online behavioural surveys and risk-assessments conducted in the clinic prior to enrolment. All information is de-identified, with each participant being issued a unique 6 digit ID.
Migratory species can travel tens of thousands of kilometers each year, spending different parts of their annual cycle in geographically distinct locations. Understanding the drivers of population change is vital for conserving migratory species, yet the challenge of collecting data over entire geographic ranges has hindered attempts to identify the processes leading to observed population changes. Here, we use remotely sensed environmental data and count data to investigate the factors driving variability in abundance in...
Data from: Competition drives the response of soil microbial diversity to increased grazing by vertebrate herbivoresDavid J. Eldridge, Manuel Delgado-Baquerizo, Samantha K. Travers, James Val, Ian Oliver, Kelly Hamonts & Brajesh K. Singh
Scientists have largely neglected the effects of grazing on soil microbial communities despite their importance as drivers of ecosystem functions and services. We hypothesised that changes in soil properties resulting from grazing regulate the diversity of soil microbes by releasing/suppressing subordinate microbial taxa via competition. To test this, we examined intensity of vertebrate herbivores influences the diversity and composition of soil bacteria and fungi at 216 soil samples from 54 sites and four microsites. Increasing...
Early mobilisation after total hip or knee arthroplasty: A multicentre prospective observational studyJustine Naylor, Ian Harris, Rajat Mittal, Wei Xuan, Matthew Chua & Andrew Hart
Early mobilisation is recommended following total hip arthroplasty (THA) or total knee arthroplasty (TKA) to prevent venous thromboembolism (VTE). We sought to determine the proportions of patients that first mobilised on post-operative day 0 (POD 0) and factors associated with earlier time to mobilisation.
Data from: Livestock grazing reinforces the competitive exclusion of small-bodied birds by large aggressive birdsJames Val, David J. Eldridge, Samantha K. Travers & Ian Oliver
1.Grazing by domestic livestock is sometimes promoted as a management tool to benefit biodiversity. In many situations, however, it can produce negative outcomes. 2.Here we examine the impacts of recent and historic livestock grazing on bird communities in the semi-arid woodlands in eastern Australia, testing the notion that grazing removes the suppressive effect of structurally complex vegetation on miners, thereby reducing the richness and abundance of small birds. 3.We used time- and area-limited searches of...
Models of aging predict that sperm function and fertility should decline with age as sperm are exposed to free radical damage and mutation accumulation. However, theory also suggests that mating with older males should be beneficial for females because survival to old age is a demonstration of a male’s high genetic and/or phenotypic quality. Consequently, declines in sperm fitness may be offset by indirect fitness benefits exhibited in offspring. While numerous studies have investigated age-based...
Data from: Interactions between rainfall, fire and herbivory drive resprouter vital rates in a semi-arid ecosystemKatherine M. Giljohann, Michael A. McCarthy, David A. Keith, Luke T. Kelly, Mark G. Tozer & Tracey J. Regan
1. Global change is threatening ecosystems and biodiversity worldwide, creating a pressing need to understand how climate and disturbance regimes interact and influence the persistence of species. We quantify how three ecosystem drivers– rainfall, fire and herbivory – influence vital rates in the perennial resprouting graminoid, Triodia scariosa, a foundation species of semi-arid Australia. 2. We used an 11 year data set from a fire and herbivore exclosure experiment, to model flowering, post-fire recruitment and...
