Infrared Synchrotron Emission in the Soft State of GX 339-4 and the Mid-Infrared/X-ray Luminosity Plane of Black Hole X-ray Binaries Open
Progress in understanding the growth of accreting black holes remains hampered by a lack of sensitive coordinated multiwavelength observations. In particular, the mid-infrared (MIR) regime remains ill-explored except for jet-dominant state…

Several candidate size metrics explain vital rates across multiple populations throughout a widespread species' range Open
Individual plant size often determines the vital rates of growth, survival and reproduction. However, size can be measured in several ways (e.g. height, biomass, leaf length). There is no consensus on the best size metric for modelling vit…

Thermal mismatch models derived from occurrence data predict pathogen prevalence in frogs Open
Emerging infectious diseases increasingly threaten many wildlife populations, yet the impacts of pathogens vary considerably both within and among host species. The environmental tolerance mismatch hypothesis (ETMH) suggests that this vari…

Quantifying the Sensitivity of Targeted <span>eDNA</span> Surveys to Improve Detection of Invasive Cane Toads (<i>Rhinella marina</i>) Open
Environmental DNA (eDNA) surveys are increasingly used to monitor biodiversity because they are often more sensitive (have higher detection probability) than conventional monitoring methods. Sensitivity is a key consideration in designing …

Developing geospatial tools to identify refuges from alien trout invasion in Australia to assist freshwater conservation Open
Context Introduced fish have caused significant range reductions for many native fish, with many threatened species now found in headwater refuges, protected by in-stream barriers such as waterfalls, weirs and culverts. Owing to the remote…

An invasive pathogen generally contracts species to their niche cores, not margins Open
Quantifying how species' distributions contract in response to threats can reveal pathways of decline and the role of environmental conditions in moderating threat impacts. Two general patterns of niche contraction have been described: eco…

Active restoration after three decades: Seed addition increases native dominance compared to landscape‐scale secondary succession Open
Active restoration often aims to accelerate ecosystem recovery. However, active restoration may not be worthwhile if its effects are overwhelmed by changes that occur passively. Moreover, it can be challenging to separate the effects of pa…

Large-scale serial replacement of invasive tench (Tinca tinca) by invasive carp (Cyprinus carpio) in the presence of redfin perch (Perca fluviatilis) in the Murray-Darling River system, Australia Open
Ecosystems worldwide are increasingly being invaded by multiple species, and the rate of biological invasion is accelerating, leading to more interactions among invasive species. One such interaction that has received little attention is t…

Boom-bust population dynamics drive rapid genetic change Open
Increasing environmental threats and more extreme environmental perturbations place species at risk of population declines, with associated loss of genetic diversity and evolutionary potential. While theory shows that rapid population decl…

Factors influencing naturalisation success in horticultural species: a case study using planting records from the inception of a planned city Open
Worldwide, many invasive plant species are garden escapees. While weed risk assessment can identify new plant introductions with weedy potential, it does not address the large number of non-native plant species already present in many regi…

Root traits vary as much as leaf traits and have consistent phenotypic plasticity among 14 populations of a globally widespread herb Open
Our understanding of plant functional trait variation among populations and how this relates to local adaptation to environmental conditions is largely shaped by above‐ground traits. However, we might expect below‐ground traits linked to r…
