Data from: Global change impacts on arid zone ecosystems: Seedling establishment processes are threatened by temperature and water stressWolfgang Lewandrowski, Jason Stevens, Bruce Webber, Emma Dalziell, Melinda Trudgen, Amber Bateman & Todd Erickson
Recruitment for many arid-zone plant species is expected to be impacted by the projected increase in soil temperature and prolonged droughts associated with global climate change. As seed dormancy is considered a strategy to avoid unfavourable conditions, understanding the mechanisms underpinning vulnerability to these factors is critical for plant recruitment in intact communities, as well as for restoration efforts in arid ecosystems. This study determined the effects of temperature and water stress on recruitment processes...
Data from: Population genetics of a broadcast-spawning coral across a tropical-temperate transition zone reveals regional differentiation and isolation of high-latitude reefsRichard Evans, Luke Thomas, W. Jason Kennington, Nicole Ryan, Nerida Wilson, Zoe Richards, Ryan Lowe & Chenae Tuckett
Aim: Genetic connectivity is a key component of species resilience to climate change in terms of recovery capacity following disturbance and capacity to disperse to novel locations as the climate warms and isotherms shift poleward. We aimed to strengthen our understanding of resilience in this context by characterizing patterns of connectivity and genetic diversity in a broadcast spawning coral across a tropical-temperate transition zone. We hypothesize genetic differentiation between tropical and temperate populations and decreasing...
Data from: Burrowing by translocated boodie (Bettongia lesueur) populations alters soils but has limited effects on vegetationBryony Palmer, Leonie Valentine, Cheryl Lohr, Gergana Daskalova & Richard Hobbs
Digging and burrowing mammals modify soil resources, creating shelter for other animals and influencing vegetation and soil biota. The use of conservation translocations to reinstate the ecosystem functions of digging and burrowing mammals is becoming more common. However, in an increasingly altered world, the roles of translocated populations, and their importance for other species, may be different. Boodies (Bettongia lesueur), a commonly translocated species in Australia, construct extensive warrens, but how their warrens affect soil...
Genotype-environment association (GEA) methods have become part of the standard landscape genomics toolkit, yet, we know little about how to best filter genotype-by-sequencing data to provide robust inferences for environmental adaptation. In many cases, default filtering thresholds for minor allele frequency and missing data are applied regardless of sample size, having unknown impacts on the results. These effects could be amplified in downstream predictions, including management strategies. Here, we investigate the effects of filtering on...
Data from: Association of putatively adaptive genetic variation with climatic variables differs between a parasite and its hostSheree Walters, Todd Robinson, Margaret Byrne, Grant Wardell-Johnson & Paul Nevill
Parasitism is a pervasive phenomenon in nature with the relationship between species driving evolution in both the parasite and host. Due to their host-dependent lifestyle, parasites may adapt to the abiotic environment in ways that differ from their hosts or from free living relatives; yet rarely has this been assessed. Here, we test two competing hypotheses related to whether putatively adaptive genetic variation in a specialist mistletoe associates with the same, or different, climatic variables...
Pollinators, and the pollination services they provide, are critical for seed set and self-sustainability of most flowering plants. Despite this, pollinators are rarely assessed in restored plant communities, where their services are largely assumed to re-establish. This data set contains the bird-pollinator richness, foraging and bird interaction behaviour between natural and restored Banksia woodland sites in Western Australia. These parameters were measured for natural communities of varying size and degree of fragmentation, and restored plant...
Genomic divergence in sympatry indicates strong reproductive barriers and cryptic species within Eucalyptus salubrisRachel Binks, Dorothy Steane & Margaret Byrne
Genetic studies are increasingly detecting cryptic taxa that likely represent a significant component of global biodiversity. However, cryptic taxa are often criticized because they are typically detected serendipitously and may not receive the follow-up study required to verify their geographic or evolutionary limits. Here, we follow-up a study of Eucalyptus salubris that unexpectedly detected two divergent lineages but was not sampled sufficiently to make clear interpretations. We undertook comprehensive sampling for an independent genomic analysis...
This dataset details the proportion of the geographic range of 26,062 Australian plant species burnt in the 2019-2020 megafire; threatened listing status on state and Commonwealth threatened species legislation; species endemic status in each state/territory according to the Australian Plant Census; and risk ranking for exposure to high fire frequency (short intervals between fires) and cumulative impacts of fire (populations dominated by immature individuals). Further details are provided in the users should consult and cite...
Reconstructing the historical fauna of a large continental island: a multispecies reintroduction risk analysisKatie Peterson, Michael Bode, Cailan Jeynes-Smith, Megan Barnes, Cailan Jeynes-Smith, Saul Cowen, Lesley Gibson, Collen Sims, Christopher Baker & Michael Bode
1. Reintroduction projects, which are an important tool in threatened species conservation, are becoming more complex, often involving the translocation of multiple species. Ecological theory predicts that the sequence and timing of reintroductions will play an important role in their success or failure. Following the removal of sheep, goats and feral cats, the Western Australian government is sequentially reintroducing 13 native fauna species to restore the globally important natural and cultural values of Dirk Hartog...
Unseasonal fire occurrence is increasing globally, driven by climate change and other human activity. Changed timing of fire can inhibit post-fire seedling recruitment through interactions with plant phenology (the timing of key processes, e.g., flower initiation, seed production, dispersal, germination), and therefore threaten the persistence of many plant species. While empirical evidence from winter-rainfall ecosystems shows that optimal seedling recruitment is expected following summer and autumn (dry season) fires, we sought experimental evidence isolating the...
In 2010, vulnerable golden bandicoots (Isoodon auratus) were translocated from Barrow Island, Western Australia, to a predator-free enclosure on the Matuwa Indigenous Protected Area. Golden bandicoots were once widespread throughout a variety of arid and semi-arid habitats of central and northern Australia. Like many small to medium-sized marsupials, the species has severely declined since colonisation and has been reduced to only four remnant natural populations. Between 2010 and 2020 the reintroduced population of golden bandicoots...
Increasing extreme wildfire occurrence globally is boosting demand to understand the fuel dynamics and fire risk of fire-prone areas. This is particularly pressing in fire-prone, Mediterranean climate-type vegetation, such as the Banksia woodlands surrounding metropolitan Perth, southwestern Australia. Despite an extensive wildland-urban interface and frequent fire occurrence, fuel accumulation and the spatial variation in fuel risk is not well quantified across the broad extent of this ecosystem. Using a space for time sampling approach to...
