Article
Competition from neighbouring trees generally has a negative effect on the growth of an individual tree; however, the magnitude of competition is expected to vary with size and proximity of the tree and its competitors. Eucalypt forests (natural/plantation) are widespread throughout the world, and have high economic, ecological and conservation imp...
Article
1. Negative conspecific interactions have been shown to promote diversity in plant communities, as have some heterospecific interactions such as intransitive competition and facilitation. However, it is unclear whether combinations of conspecific and other heterospecific interactions can also promote diversity in plant communities. We therefore inv...
Article
In the present study, we tested the chronological and geographic origins of the mostly arid Australian Ptilotus (Amaranthaceae) and its close relatives (i.e. the ‘aervoids’) by reconstructing a dated phylogeny with near-comprehensive sampling for Ptilotus and estimating ancestral geographic ranges. We investigated climatic niche evolution within Pt...
Article
Mining activity causes major changes in site topography, soil physical and chemical properties, hydrology, and biological assemblages. Reassembling plant communities in these highly altered environments is dependent on interactions between environmental drivers and management intervention techniques through time, yet the long‐term effects of these...

Rainfall regimes in many parts of the world have become increasingly dominated by fewer, but more extreme, rainfall events. Understanding how tree growth responds to changes in the frequency and intensity of rain events is critical to predicting how climate change will impact on forests and woodlands in the future. In this study, we used five tree‐...

Habitat loss has reduced the available resources for apiarists and is a key driver of poor colony health, colony loss, and reduced honey yields. The biggest challenge for apiarists in the future will be meeting increasing demands for pollination services, honey, and other bee products with limited resources. Targeted landscape restoration focusing...
Article
Growth of an individual tree in a forest depends on multiple factors amongst which size, age and stand density can be of particular importance. The ability to understand how these factors influence individual growth can help understand forest growth and dynamics more generally. The overall objective of this study was to analyse the growth of indivi...

Full-text available
Globally, many biomes are being impacted by significant shifts in total annual rainfall as well as increasing variability of rainfall within and among years. Such changes can have potentially large impacts on plant productivity and growth, but remain largely unknown, particularly for much of the Southern Hemisphere. We investigate how growth of the...
Article
Long‐term studies of vegetation recovery following post‐mining restoration in low productivity, high stress areas are limited, but essential for understanding underlying ecological processes and evaluating management practices. This study's goal was to describe temporal patterns of recovery (up to 37 years) in vegetation structure, floristic divers...
Article
Full-text available
Sponge transcriptomes are important resources for studying the stress responses of these ecologically important filter feeders, the interactions between sponges and their symbionts, and the evolutionary history of metazoans. Here, we generated reference transcriptomes for two common and cosmopolitan Indo-Pacific sponge species: Carteriospongia foli...
Article
The food environment is a target for policy interventions aimed at improving diet, but there is a lack of consistent evidence to guide such policy interventions, partially attributed to spatial measures of the food environment that are too narrow in scope. This study developed a workflow in the R programming language for characterising food access...
Article
Full-text available
Rotating crop cultivars with different resistance genes could slow the evolution of virulent strains of fungal pathogens, but could also produce highly virulent pathogen strains. We present a new model that links polycyclic pathogen epidemiology and population genetics in order to predict how different strategies of rotating cultivars with differen...
Article
A variety of techniques for measuring coral growth, a fundamental biological trait, have been used to improve our understanding of coral demographics. Remaining gaps and biases in this information, in combination with technological advances, led to the present study. We assessed the capacity of structure-from-motion (SfM) technology to build image...
Article
Full-text available
Scleractinian corals, which create complex three-dimensional carbonate structures, are the foundation of coral reef ecosystems. There are a variety of coral growth forms or ‘morphologies’ that have distinct advantages and disadvantages when corals compete for space and light, and when they are exposed to hydrodynamic disturbances. We developed a no...

Transcriptomes from sponges are important resources for studying the stress responses of these ecologically important filter feeders, the interactions between sponges and their symbionts, and the evolutionary history of metazoans. Here, we generated reference transcriptomes for two common and cosmopolitan Indo-Pacific sponge species: Carteriospongi...
Article
The concepts of traits, plant functional types (PFT), and functional communities are effective tools for the study of complex phenomena such as plant community assembly. Here, we (1) suggest a procedure formalising the classification of response traits to construct a PFT system; (2) integrate the PFT, and species compositional data to formally defi...
Conference Paper
The success of mine site rehabilitation using native seeds is hampered by poor seedling establishment. Seed enhancement treatments including seed coatings and pelleting form one strategy to improve establishment. However, for some seeds, particularly those of grasses, irregular shapes and surface features of covering floret structures are difficult...
Article
Full-text available
The regeneration niche defines the specific environmental requirements of the early phases of a plant's life cycle. It is critical for the long-term persistence of plant populations, particularly for obligate seeders that are highly vulnerable to stochastic events in fire-prone ecosystems. Here, we assessed germination characteristics and the relat...
Article
The composition of mammalian communities in Australia's Eucalyptus forests and woodlands is known to be affected by fire. However, there are few published studies that compare mammal assemblages in recently burnt and long‐unburnt forests because there are few areas with long‐term fire history data. Understanding the value of long‐unburnt forest is...
Article
Full-text available
Fencelines and field margins in broad-acre cropping systems are commonly a refuge for weeds, diseases and invertebrates because they avoid many cropping and pest management regimes applied inside fields. As such, fenceline refuges are often managed separately with the goal to reduce pest reinfestation of fields from the margins. However, the implic...
Article
Background: Weed resistance to foliar herbicides has dramatically increased worldwide in the last two decades. As a consequence, current practices of weed management have changed with an increased adoption of soil-applied herbicides to restore control of herbicide-resistant weeds. We foresee metabolism-based resistance and cross-resistance to soil...
Article
The nature of community patterns and environmental drivers in kwongan mediterranean‐type shrubland on nutrient‐poor soils occurring in Western Australia remain poorly examined. We aimed to determine whether (i) classification of the kwongan vegetation of the northern Swan Coastal Plain would be ecologically informative and (ii) which environmental...

Potato cyst nematodes (PCN) are damaging soil-borne quarantine pests of potatoes in many parts of the world. There are two recognised species, Globodera pallida and G. rostochiensis, with only the latter species - the golden cyst nematode - present in Australia. PCN was first discovered in Australia in 1986 in Western Australia, where it was subseq...
Article
Questions The community patterns in kwongan, a mediterranean‐type scrub on nutrient‐poor soils occurring in Western Australia, are poorly understood due to only few, focused studies using disparate sampling designs. We aimed to determine whether (1) classification of the kwongan vegetation of the Eneabba Sandplains leads to an ecologically informat...

Full-text available
Honeydew production by Hemiptera is an ecologically important process that facilitates mutualisms and increases nutrient cycling. Accurate estimates of the amount of honeydew available in a system are essential for quantifying food web dynamics, energy flow, and the potential growth of sooty mould that inhibits plant growth. Despite the importance...

Article
Harvest weed seed control (HWSC) techniques have been implemented in Australian cropping systems to target and reduce the number of weed seeds entering the seedbank and thereby reduce the number of problematic weeds emerging in subsequent years to infest subsequent crops. However, the influence of HWSC on ameliorating herbicide-resistance (HR) evol...

Full-text available
BACKGROUND Surveillance strategies are often standardized and completed on grid patterns to detect pest incursions quickly; however, it may be possible to improve surveillance through more targeted surveillance that accounts for landscape heterogeneity, dispersal and the habitat requirements of the invading organism. We simulated pest spread at a l...
Article
The need to integrate the ever-expanding body of knowledge in the plant sciences has led to the development of sophisticated modelling approaches. This special issue focuses on functional-structural plant (FSP) models, which are the result of cross-fertilization between the domains of plant science, computer science and mathematics. FSP models simu...
Article
Harvest weed seed destruction (HWSD) can be included in an integrated weed management (IWM) program to help control weed populations and combat herbicide resistance. However, it may not be possible or practical to use this technique in every year. This research utilised a computer model, the Weed Seed Wizard, to investigate the impact of employing...

Full-text available
Weedy plants pose a major threat to food security, biodiversity, ecosystem services and consequently to human health and wellbeing. However, many currently used weed management approaches are increasingly unsustainable. To address this knowledge and practice gap, in June 2014, 35 weed and invasion ecologists, weed scientists, evolutionary biologist...
Article
Full-text available
We investigated how an invading organism’s dispersal characteristics affect the efficacy of different surveillance strategies aimed at detecting that organism as it spreads following a new incursion. Specifically, we assessed whether, out of the surveillance strategies tested, the best surveillance strategy for an organism varied depending on the w...

Plant-soil feedbacks (PSFs) are plant-induced changes to the abiotic and/or biotic properties of soil that positively or negatively impact plant growth. Recently, PSFs have been shown to play a key role in both promoting and maintaining high levels of diversity within plant communities. There is mounting evidence that diversity loss leads to reduce...
Conference Paper
Full-text available
In biological systems, structural complexity is recognized as an important driver of coexistence and species diversity. This is particularly true for coral reefs, where some of the most biodiverse life on Earth coexists. A key contributor to reef structural complexity is the varied morphologies into which reef corals can grow. A large number of cor...
