Data from: Amelioration of ocean acidification and warming effects through physiological buffering of a macroalgae

Steve Doo, Aero Leplastrier, Alexia Graba-Landry, Januar Harianto, Ross Coleman & Maria Byrne
Concurrent anthropogenic global climate change and ocean acidification is expected to have a negative impact on calcifying marine organisms. While knowledge of biological responses of organisms to oceanic stress has emerged from single species experiments, these do not capture ecologically relevant scenarios where the potential for multi-organism physiological interactions is assessed. Marine algae provide an interesting case study, as their photosynthetic activity elevates pH in the surrounding microenvironment, potentially buffering more acidic conditions for associated...

Colonization history affects heating rates of invasive cane toads

Gregory P. Brown, Richard Shine & Georgia Kosmala
Amphibians in hot climates may be able to avoid high temperatures by controlling their rates of heating. In northern Australia, invasive cane toads (Rhinella marina) experience hot dry conditions in newly-colonized (western) sites but milder conditions in longer-occupied (eastern) sites. Under standardized conditions, toads from western sites heated less rapidly than did conspecifics from an eastern site. The availability of free water slowed heating rates of eastern but not western toads. Thus, the colonization of...

Data for: Angels in disguise: Sympatric hybridization in the marine angelfishes is widespread and occurs between deeply divergent lineages

Yi-Kai Tea, Jean-Paul Hobbs, Federico Vitelli, Joseph DiBattista, Simon Ho & Nathan Lo
Hybridization is not uncommon in marine environments where physical barriers are attenuated. Research conducted on hybridization in coral reefs has grown rapidly, but the majority of studies have focused on parapatric species along biogeographical suture zones. Comparatively little attention has been directed towards sympatric hybridization on coral reefs, despite the large amount of biogeographical overlap that occurs among coral reef species. Here we investigate if the propensity for hybridization along suture zones represents a general...

Stability of elemental content correlates with plant resistance to soil impoverishment

Ruzhen Wang, Linyou Lü, Yanzhuo Cao, Jordi Sardans, Heyong Liu, Yuge Zhang, Josep Peñuelas, Feike Dijkstra & Yong Jiang
Aims We investigated whether plant resistance to soil impoverishment would depend on their flexibility in taking up nutrients and on maintaining elemental stoichiometry. Methods We mixed sand with grassland soil in mass proportions of 0, 10, 30, 50 and 70% to simulate soil impoverishment as caused by a gradient of desertification intensity and examined how plant nitrogen (N) uptake (15NH4NO3 and NH415NO3 labelling) and nutrient stoichiometry were associated with plant growth responses of a sedge...

The hidden army: coralivorous Crown of Thorns seastars can spend years as herbivorous juveniles

Dione Deaker, Antonio Agüera, Huang-An Lin, Corinne Lawson, Claire Budden, Symon Dworjanyn, Benjamin Moss & Maria Byrne
Crown of Thorns seastar (COTS) outbreaks are a major threat to coral reefs. Although the herbivorous juveniles and their switch to corallivory are key to seeding outbreaks, they remain a black box in our understanding of COTS. We investigated the impact of a delay in diet transition due to coral scarcity in cohorts reared on coralline algae for 10 months and 6.5 yrs before being offered coral. Both cohorts achieved an asymptotic size (16–18 mm...

Nightly selection of resting sites and group behavior reveal anti-predator strategies in giraffe

Anna Lena Burger, Julian Fennessy, Stephanie Fennessy & Paul W. Dierkes
This study presents the first findings on nocturnal behavior patterns of wild Angolan giraffe. We characterized their nocturnal behavior and analyzed the influence of ecological factors such as group size, season and habitat use. Giraffe were observed using night vision systems and thermal imaging cameras on Okapuka Ranch, Namibia. A total of 77 giraffe were observed during 24 nights over two distinct periods – July-August 2016 (dry season) and February-March 2017 (wet season). Photoperiod had...

Queen pheromone modulates the expression of epigenetic modifier genes in the brain of honeybee workers

, Isobel Ronai, Klaus Hartfelder & Benjamin Oldroyd
Pheromones are used by many insects to mediate social interactions. In the highly eusocial honeybee (Apis mellifera) queen mandibular pheromone (QMP) is involved in the regulation of the reproductive and other behaviour of workers. The molecular mechanisms by which QMP acts are largely unknown. Here we investigate how genes responsible for epigenetic modifications to DNA, RNA and histones respond to the presence of QMP in the environment. We show that several of these genes are...

Flick SMART multi-catch rodent station and bait station data sets: Council of the city of Sydney, October 2019 to July 2020

Miguel A Bedoya Perez, Michael P Ward, Max Loomes & Mathew S Crowther
Shortly after the enactment of preventative measures aimed at limiting the spread of COVID-19, local governments and public health authorities around the world reported an increased sighting of rats. We combined multi-catch rodent station data, rodent bait stations data, and rodent-related residents’ complaints data to explore the effects that social distancing and lockdown measures might have had on the rodent population within the City of Sydney, Australia. We found that rodent captures, activity, and rodent...

Data from: Tradeoffs affect the adaptive value of plasticity: Stronger cannibal-induced defenses incur greater costs in toad larvae

Jayna DeVore, Michael Crossland & Richard Shine
Adaptive developmental plasticity allows individuals to match their phenotype with their environment, which can increase fitness where threats are inconsistently present. Because adaptive traits are not ubiquitously nor infinitely plastic, tradeoffs between benefits and costs or limits are theoretically necessary to constrain plastic responses. Systems in which extreme risk can be reliably detected are ideal for investigating mechanisms that constrain plasticity, as even costly responses may be adaptive where risk is severe. Cane toads (Rhinella...

Differences in oxidative status explain variation in thermal acclimation capacity between individual mosquitofish (Gambusia holbrooki)

Frank Seebacher & Isabella Loughland
1. Evolutionary theory predicts that the capacity to acclimate should be favoured in variable environments. However, perfect compensation for thermal variation is rare and the capacity for thermal acclimation can vary considerably between individuals within natural populations. This variation may be explained by costs associated with acclimation, but it is not clear what these costs are. 2. We tested the hypothesis that oxidative stress is a cost of acclimation that could explain the variation between...

Data from: Deciphering genetic mate choice: not so simple in group-housed conservation breeding programs

Katherine Farquharson, Carolyn Hogg, Katherine Belov & Catherine Grueber
Incorporating mate choice into conservation breeding programs can improve reproduction and the retention of natural behaviours. However, different types of genetic-based mate choice can have varied consequences for genetic diversity management. As a result, it is important to examine mechanisms of mate choice in captivity to assess its costs and benefits. Most research in this area has focused on experimental pairing trials, however this resource-intensive approach is not always feasible in captive settings and can...

Carbon allocation to the rhizosphere is affected by drought and nitrogen addition

Ruzhen Wang, Timothy Cavagnaro, Yong Jiang, Claudia Keitel, Feike Dijkstra, Timothy R. Cavagnaro & Feike A. Dijkstra
Photosynthetic carbon (C) allocated below-ground can be shared with mycorrhizal fungi in exchange for nutrients, but also added into soil as rhizodeposits that potentially increases plant nutrient supply by supporting microbial nutrient mineralization from organic matter. How water and nitrogen (N) availabilities affect plant C allocation to the rhizosphere, including both arbuscular mycorrhizal fungi (AMF) symbionts and rhizodeposits, remains largely unknown. We used a 13CO2 pulse labelling experiment to assess effects of drought and N...

The geometry of resource constraint: an empirical study of the golden snub-nosed monkey

Rong Hou, Colin Chapman, Jessica Rothman, He Zhang, Kang Huang, Songtao Guo, Baoguo Li & David Raubenheimer
1. Apposite conceptualization and measurement of resource variation is critical for understanding many issues in ecology, including ecological niches, persistence and distribution of populations, the structure of communities, and population resilience to perturbations. 2. We apply the nutritional geometry framework to conceptualise and quantify the responses of a temperate-living primate, the golden snub-nosed monkey (Rhinopithecus roxellana) to variation in resource quality and quantity and in nutrient requirements associated with seasonal environments. 3. We present a...

Missionaries on a Pilgrimage, or Pilgrims on a Mission? Elements of Pilgrimage in The Church of Jesus Christ of Latter-day Saints Missionary Experience

Elisha McIntyre & Daniel H. Olsen
The purpose of this paper is to consider the ways in which proselytizing missions by members of The Church of Jesus Christ of Latter-day Saints are pilgrimage-like. After outlining the historical and theological background behind the Church’s missionary efforts and discuss how this missionary work is organized both practically and social, the similarities between Church missions and religious pilgrimage are compared based on six themes: journeying and the sacred, liminality, communitas, hardships, status, and change...

Feasibility assessment of Bioenergy with Carbon Capture and Storage (BECCS) deployment with Municipal Solid Waste (MSW) co-combustion at New South Wales (NSW) coal power plants

Gustavo Fimbres Weihs, Minh Ho, Dianne Wiley, Rameen Hayat Malik, Joseph Jones, Ali Abbas, Jake Zhai, Wahyu Meka & Paul Fennell
Burning coal to produce electricity is one of the main contributors of carbon dioxide emissions to the atmosphere. This study aims to find out if it is practical and cost-effective to reduce those emissions in NSW by burning waste materials along with the coal, separating the carbon dioxide from the rest of the combustion gases and storing the carbon dioxide deep underground Municipal Solid Waste (MSW), or rubbish, is a combination of many different materials,...

Data from: The global diversity and distribution of lizard clutch sizes

Shai Meiri, Luciano Avila, Aaron Bauer, David Chapple, Indraneil Das, Tiffany Doan, Paul Doughty, Ryan Ellis, Lee Grismer, Fred Kraus, Mariana Morando, Paul Oliver, Daniel Pincheira-Donoso, Marco-Antonio Ribeiro-Junior, Glenn Shea, Omar Torres-Carvajal, Alex Slavenko & Uri Roll
Aim. Clutch size is a key life-history trait. In lizards, it ranges over two orders of magnitude. The global drivers of spatial and phylogenetic variation in clutch have been extensively studied in birds, but such tests in other organisms are lacking. To test the generality of latitudinal gradients in clutch size, and their putative drivers, we present the first global-scale analysis of clutch sizes across of lizard taxa. Location, Global Time period. Recent Major taxa...

Data from: Upgrades of coastal protection infrastructure affect benthic communities

Lea Mamo, Augustine Porter, Alejandro Tagliafico, Melinda Coleman, Stephen Smith, Will Figueira & Brendan Kelaher
Sea level rise, storm surges, aging and wear are forcing upgrades to breakwaters and seawalls to protect coastal areas from erosion and inundation. Such upgrades involve the introduction of new material which may consequently act as an ecological disturbance that can alter established marine communities and ecosystem function. Mitigating ecological impacts requires an understanding of how species assemblages are affected by such works. Here, we use the major upgrade of a regularly wave-overtopped breakwater as...
