Partially Penetrating Lake-Aquifer Interaction in a Laboratory-scale Tidal Setting

Amir Jazayeri, Adrian Werner & Nick Cartwright
Freshwater lakes close to the coast are important ecotones with strong functional dependency on ocean forces. Tides are likely to create dynamic lake-groundwater interactions, which have not been previously assessed for partially penetrating lakes. This study investigates tidal lake-groundwater interaction in a laboratory-scale aquifer cross-section with and without the existence of a partially penetrating lake. The experimental observations were reproduced by numerical models to allow for an in-depth evaluation of the experiments beyond those provided...

Spatial dynamics of pathogen transmission in communally roosting species: Impacts of changing habitats on bat-virus dynamics

Tamika Lunn, Tamika Lunn, Alison Peel, Hamish McCallum, Peggy Eby, Maureen Kessler, Raina Plowright & Olivier Restif
1. The spatial organisation of populations determines their pathogen dynamics. This is particularly important for communally roosting species, whose aggregations are often driven by the spatial structure of their environment. 2. We develop a spatially explicit model for virus transmission within roosts of Australian tree-dwelling bats (Pteropus spp.), parameterised to reflect Hendra virus. The spatial structure of roosts mirrors three study sites, and viral transmission between groups of bats in trees was modelled as a...

Natural disturbance impacts on trade-offs and co-benefits of forest biodiversity and carbon

Martin Mikoláš, Marek Svitok, Radek Bače, Garrett Meigs, William Keeton, Heather Keith, Arne Buechling, Volodymyr Trotsiuk, Kurt Bollmann, Krešimir Begovič, Vojtěch Čada, Oleh Chaskovskyy, Dheeraj Ralhan, Martin Dušátko, Matej Ferenčík, Michal Frankovič, Rhiannon Gloor, Jeňýk Hofmeister, Pavel Janda, Ondrej Kameniar, Daniel Kozák, Jana Lábusová, Linda Majdanová, Thomas Nagel, Jakob Pavlin … & Miroslav Svoboda
With accelerating environmental change, understanding the influence of forest disturbances and trade-offs between biodiversity and carbon dynamics is of high socio-economic importance. Most studies, however, have assessed immediate or short-term effects of disturbance, while long-term impacts remain poorly understood. Here, using a tree-ring-based approach, we modelled the effect of 250 years of disturbances on present-day biodiversity indicators and carbon dynamics in well-preserved European temperate primary forests. Our results indicated that disturbance legacies spanning centuries shaped...

Mangrove sinkholes (cenotes) of the Yucatan Peninsula, a global hotspot of carbon sequestration

Maria Fernanda Adame, Nadia Santini, Olmo Torres-Talamante & Kerrylee Rogers
Mangroves are amongst the most carbon-dense ecosystems on the Planet. The capacity of mangrove forests to accumulate carbon has been assessed and reported at regional, national and global scales. However, small-scale sampling is still revealing ‘hot spots’ of carbon accumulation. This study reports one of these “hotspots” with one of the largest-recorded carbon stocks in the sinkholes (cenotes) of the Yucatan Peninsula, Mexico. We assessed soil organic carbon (SOC) stocks from deep soils (1 to...

Exploration into if the phylogenetic relationships among non-Pama-Nyungan languages is mirrored by their speakers' genomic phylogenetic relationships, to test the likelihood of multiple migrations into Australia before European arrival

This project aims to test the likelihood of multiple migrations into Australia before European arrival and determine if the phylogenetic relationships among non-Pama-Nyungan languages is mirrored by their speakers' genomic phylogenetic relationships. The non-Pama-Nyungan First People of Australia speak an extraordinary number and diversity of Aboriginal languages, but the origins of these languages and the genomic diversity of the people who speak them are only now starting to be understood.

Genomic analyses inform on migration events during the peopling of Eurasia

High-coverage whole-genome sequence studies have so far focused on a limited number1 of geographically restricted populations2,3,4,5, or been targeted at specific diseases, such as cancer6. Nevertheless, the availability of high-resolution genomic data has led to the development of new methodologies for inferring population history7,8,9 and refuelled the debate on the mutation rate in humans10. Here we present the Estonian Biocentre Human Genome Diversity Panel (EGDP), a dataset of 483 high-coverage human genomes from 148 populations...

Data from: The stoichiometric signature of high-frequency fire in forest floor food webs

Orpheus Butler, Tom Lewis, Sarah Maunsell, Mehran Rezaei Rashti, James Elser, Brendan Mackey & Chengrong Chen
Fire regimes are shifting under climate change. Decadal-scale shifts in fire regime can disrupt the biogeochemical cycling of carbon (C), nitrogen (N), and phosphorus (P) within forest ecosystems, but the full extent of these disruptions is unknown. It is also unclear whether these disruptions have consequences for the ecological characteristics (e.g., biomass, abundance, and composition) of microbial and invertebrate communities, which together comprise the majority of terrestrial biodiversity and underpin many ecosystem processes. The theoretical...

The dark side of rocks: an underestimated high-quality food resource in river ecosystems

Fen Guo, Stuart Bunn, Michael Brett, Hannes Hager & Martin Kainz
This dataset contains data of fatty acid profiles described in the paper: “Guo et al. (2021) The dark side of rocks: an underestimated high-quality food resource in river ecosystems. Journal of Ecology, https://doi.org/10.1111/1365-2745.13647”. This study was a field investigation conducted along a subalpine river continuum in Austria and aimed to identify the nutritional role of a “hidden” food resource for aquatic consumers; the biofilms growing on the underside of rocks (dark biofilms). Dark and light...

Global sediment export based on InVEST Sediment Delivery Ratio model

Andrés F. Suarez Castro, Hawthorne L. Beyer, Caitlin D. Kuempel, Simon Linke, Pasquale Borrelli & Ove Hoegh-Guldberg
Sediment runoff from disturbed coastal catchments is a major threat to marine ecosystems. Understanding where sediments are produced and where they are delivered enables managers to design more effective strategies for improving water quality. In this context, targeted restoration of degraded terrestrial areas provides opportunities to reduce land-based runoff from coastal areas and consequently foster coral reef conservation. To do this strategically, a systematic approach is needed to identify watersheds where restoration actions will provide...

The iron-responsive genome of the chiton Acanthopleura granulata

Kevin Kocot, Rebecca M Varney, Daniel I Speiser, Carmel McDougall, Bernard M Degnan & Kevin M Kocot
Molluscs biomineralize structures that vary in composition, form, and function, prompting questions about the genetic mechanisms responsible for their production and the evolution of these mechanisms. Chitons (Mollusca, Polyplacophora) are a promising system for studies of biomineralization because they build a range of calcified structures including shell plates and spine- or scale-like sclerites. Chitons also harden the calcified teeth of their rasp-like radula with a coat of iron (as magnetite). Here we present the genome...

Floral attraction and flower visitors of a subcanopy tropical rainforest tree, F. picrosperma_Data

Elektra Grant, Helen Wallace, Peter Brooks, Chris Burwell, Paul Reddell & Steven Ogbourne
1. Flowering plants in tropical rainforests rely heavily on pollen vectors for successful reproduction. Research into pollination systems in tropical rainforests is dominated by canopy species, while subcanopy plant-pollinator interactions remain under-represented. The microclimate beneath the rainforest canopy is characterised by low light levels and is markedly different from the canopy environment that receives more light energy. 2. We studied the floral attractants and floral visitors of a dioecious, subcanopy tree, Fontainea picrosperma (Euphorbiaceae) in...

Ancient mtDNA sequences from the First Australians revisited

The earliest known inhabitants of Australia lived more than 42,000 years ago on the shores of Lake Mungo. Presented is data that show it is feasible to recover complete genomes of some early Australians, in addition to the sex and mitochondrial genomes of others. These data will provide a new understanding of the robust and gracile morphologies of these people, as well as the dispersal patterns of modern humans out of Africa.

Male reproductive effort might be evolving in the face of devastating disease in a threatened amphibian

Laura Brannelly, Rebecca J Webb, Zhixuan Jiang, Lee Berger, Lee F Skerratt & Laura F Grogan
The devastating infectious disease chytridiomycosis has caused declines of amphibians across the globe, yet some populations are persisting and even recovering. One understudied effect of wildlife disease is changes in reproductive effort. Here we aimed to understand if disease has plastic effects on reproduction and if reproductive effort could evolve with disease endemism. We compared the effects of experimental pathogen exposure (trait plasticity) and population-level disease history (evolution in trait baseline) on reproductive effort using...

Mycorrhizal effects on decomposition and soil CO2 flux depend on changes in nitrogen availability during forest succession

Ruiqiang Liu, Yanghui He, Guiyao Zhou, Junjiong Shao, Lingyan Zhou, Huimin Zhou, Nan Li, Bingqian Song, Chao Liang, Enrong Yan, Xiao-Yong Chen, Xihua Wang, Minhuang Wang, Shahla Hosseini Bai, Xuhui Zhou & Richard Phillips
Mycorrhizal fungi play a central role in plant nutrition and nutrient cycling, yet our understanding on their effects on free-living microbes, soil carbon (C) decomposition and soil CO2 fluxes remains limited. Here we used trenches lined with mesh screens of varying sizes to isolate mycorrhizal hyphal effects on soil C dynamics in subtropical successional forests. We found that the presence of mycorrhizal hyphae suppressed soil CO2 fluxes by 17% in early-successional forests, but enhanced CO2...

Power and limitations of environmental DNA metabarcoding for surveying leaf litter eukaryotic communities

Carla Martins Lopes, Délio Baêta, Thais Sasso, Agustín Vanzetti, Kelly Zamudio, Pierre Taberlet & Célio Haddad
Leaf litter habitats shelter a great variety of organisms, which play an important role in ecosystem dynamics. However, monitoring species in leaf litter is challenging, especially in highly diverse environments such as tropical forests, because individuals may easily camouflage themselves or hide in the litter layer. Identifying species based on environmental DNA (eDNA) would allow us to assess biodiversity in this microhabitat, without the need for direct observation of individuals. We applied eDNA metabarcoding to...

Counterintuitive scaling between population abundance and local density: implications for modelling transmission of infectious diseases in bat populations

Tamika Lunn, Alison Peel, Peggy Eby, Remy Brooks, Raina Plowright, Maureen Kessler & Hamish McCallum
1. Models of host-pathogen interactions help to explain infection dynamics in wildlife populations and to predict and mitigate the risk of zoonotic spillover. Insights from models inherently depend on the way contacts between hosts are modelled, and crucially, how transmission scales with animal density. 2. Bats are important reservoirs of zoonotic disease and are among the most gregarious of all mammals. Their population structures can be highly heterogenous, underpinned by ecological processes across different scales,...

Effect of Physical Activity Intelligence (PAI) monitoring in the maintenance phase of cardiac rehabilitation: A mixed methods evaluation

Amanda Hannan, Wayne Hing, Jeff Coombes, Suzanne Gough, Mike Climstein, Geoff Adsett, Satyajit Rohan Jayasinghe & James Furness
Dataset of the results of PAI monitoring on the amount and/or intensity of physical activity for people with cardiac disease and participants’ perceptions of this approach.

Sacred Ibis debate: The first test of evolution

This data is a comparison study into the "Sacred Ibis debate"; which predates the so-called "Great Debate" between Cuvier and Geoffroy Saint-Hilaire and the publication of Darwin's On the Origin of Species five decades later. Cuvier's views and his study had a profound influence on the scientific and public perception of evolution, setting back the acceptance of evolutionary theory in Europe for decades.

Complete genomes from sub-fossil bones of ancient Indian and Indigenous Australian and comparison

Sequencing of complete genomes from sub-fossil bones of ancient Indian and Indigenous Australian people, in the aim of investigating this possible India-Australia connection as per initial colonisation of Australia around 45,000 years ago

Exploring integrated ArtScience experiences to foster nature connectedness through head, heart, and hand

Christina Renowden, Tanja Beer & Luis Mata
1. Human activities continue to inflict profound detrimental impacts on biodiversity, yet we have not observed a commensurate shift in people’s mindsets to achieve a more harmonious relationship between people and nature. As such, the need to shift the publics’ perspective and awareness of their interconnectedness with nature continues to drive education and communication programs that aim to deepen the connection between people and nature. 2. This has led to mounting interest in integrating art...

Longitudinal variation in the nutritional quality of basal food sources and its effect on invertebrates and fish in subalpine rivers

Fen Guo, Nadine Ebm, Stuart Bunn, Michael Brett, Hannes Hager & Martin Kainz
1. There is growing recognition of the importance of food quality over quantity for aquatic consumers. In streams and rivers, most previous studies considered this primarily in terms of the quality of terrestrial leaf litter and importance of microbial conditioning. However, many recent studies suggest that algae are a more nutritional food source for riverine consumers than leaf litter. To date, few studies have quantified longitudinal shifts in the nutritional quality of basal food resources...
