Arctic shrub colonization lagged peak postglacial warmth: Molecular evidence in lake sediment from Arctic CanadaSarah Crump, Gifford Miller, Matthew Power, Julio Sepúlveda, Nadia Dildar, Megan Coghlan & Michael Bunce
Arctic shrubification is an observable consequence of climate change, already resulting in ecological shifts and global-scale climate feedbacks including changes in land surface albedo and enhanced evapotranspiration. However, the rate at which shrubs can colonize previously glaciated terrain in a warming world is largely unknown. Reconstructions of past vegetation dynamics in conjunction with climate records can provide critical insights into shrubification rates and controls on plant migration, but paleoenvironmental reconstructions based on pollen may be...
MicroCT images of residual CO2 trapping in oil wet sandstone.
Avian eggshell is a bio-ceramic material with exceptional properties for preserving DNA within its crystalline structure, presenting an opportunity to retrieve genomic information from extinct or historic populations of birds. However, intracrystalline DNA has only been recovered from the large, thick eggshell of palaeognaths; members of their more-diverse sister group (neognaths) lay smaller, thinner eggs that may not exhibit the same propensity for DNA preservation. Here, we use three 40-60 year-old museum eggshell specimens of...
1. Periodically harvested closures are a widespread, centuries-old form of fisheries management that protects fish between pulse harvests and can generate high harvest efficiency by reducing fish wariness of fishing gear. However, the ability for periodic closures to also support high fisheries yields and healthy marine ecosystems is uncertain, despite increased promotion of periodic closures for managing fisheries and conserving ecosystems in the Indo-Pacific. 2. We developed a bioeconomic fisheries model that considers changes in...
Effect of in-situ mineral dissolution on high salinity of flowback water during hydraulic fracturing in shalesLingping Zeng, Nathan Reid, Yunhu Lu, Mofazzal Hossain, Ali Saeedi & Quan Xie
Hydraulic fracturing has been widely implemented to enhance hydrocarbon production from shale reservoirs. However, one of the main challenges during hydraulic fracturing is to understand the high salinity of flowback water (up to 300,000 mg/L). While several mechanisms have been proposed to explain the controlling factor behind this phenomenon, less attention has been paid to quantify the contribution of fluid-shale interactions such as mineral dissolution and surface complexation on fluid salinity. We thus conducted spontaneous...
Data from: Digging for DNA at depth: rapid universal metabarcoding surveys (RUMS) as a tool to detect coral reef biodiversity across a depth gradientJoseph D. DiBattista, James D. Reimer, Michael Stat, Giovanni D. Masucci, Piera Biondi, Maarten De Brauwer & Michael Bunce
Background. Effective biodiversity monitoring is fundamental in tracking changes in ecosystems as it relates to commercial, recreational, and conservation interests. Current approaches to survey coral reef ecosystems center on the use of indicator species and repeat surveying at specific sites. However, such approaches are often limited by the narrow snapshot of total marine biodiversity that they describe and are thus hindered in their ability to contribute to holistic ecosystem-based monitoring. In tandem, environmental DNA (eDNA)...
Aim The mutualistic relationship between anemones and anemonefishes is one of the most iconic examples of symbiosis. However, while anemonefishes have been extensively studied in terms of genetic connectivity, such information is lacking entirely for host sea anemones. Here, we provide the first information on the broad-scale population structure and phylogeographic patterns of three species of host sea anemone, Heteractis magnifica, Stichodactyla mertensii, and Entacmaea quadricolor. We evaluate if there is concordance in genetic structure...
Data from: Marine environmental DNA biomonitoring reveals seasonal patterns in biodiversity and identifies ecosystem responses to anomalous climatic eventsTina E. Berry, Benjamin J. Saunders, Megan L. Coghlan, Michael Stat, Simon Jarman, Anthony J. Richardson, Claire H. Davies, Oliver Berry, Euan S. Harvey & Michael Bunce
Marine ecosystems are changing rapidly as the oceans warm and become more acidic. The physical factors and the changes to ocean chemistry that they drive can all be measured with great precision. Changes in the biological composition of communities in different ocean regions are far more challenging to measure because most biological monitoring methods focus on a limited taxonomic or size range. Environmental DNA (eDNA) analysis has the potential to solve this problem in biological...
High resolution distribution modelling of a threatened short-range endemic plant informed by edaphic factors.Sean Tomlinson, Wolfgang Lewandrowski, Carole Elliott, Ben Miller & Shane Turner
Short-range endemic plants often have edaphic specialisations that, with their restricted distributions, expose them to increased risk of anthropogenic extinction. Here, we present a modelling approach to understand habitat suitability for Ricinocarpos brevis R.J.F.Hend. & Mollemans (Euphorbiaceae), a threatened shrub confined to three isolated populations in the semi-arid south-west of Western Australia. The model is a maximum entropy species distribution projection constructed on the basis of physical soil characteristics and geomorphology data at approximately 25...

Aim: To test hypothesized biogeographic partitions of the tropical Indo-Pacific Ocean with phylogeographic data from 56 taxa, and to evaluate the strength and nature of barriers emerging from this test. Location: The Indo-Pacific Ocean. Time Period: Pliocene through the Holocene. Major Taxa Studied: 56 marine species. Methods: We tested eight biogeographic hypotheses for partitioning of the Indo-Pacific using a novel modification to analysis of molecular variance. Putative barriers to gene flow emerging from this analysis...
