Blue carbon is fast garnering international interest for its disproportionate contribution to global carbon stocks. However, our understanding of the size of these blue carbon stocks, as well as the provenance of carbon that is stored within them, is still poor. This is especially pertinent for many small-island nations that may have substantial bl...

The soil in terrestrial and coastal blue carbon ecosystems is an important carbon sink. National carbon inventories require accurate assessments of soil carbon in these ecosystems to aid conservation, preservation, and nature-based climate change mitigation strategies. Here we harmonise measurements from Australia’s terrestrial and blue carbon ecos...

Many degraded ecosystems need active restoration to conserve biodiversity and re‐establish ecosystem function, both highlighted targets of the UN Decade on Ecosystem Restoration and the proposed EU Nature restoration law. Soil translocation, where both plant propagules and their associated soil biota are co‐introduced, has increasingly been propose...

Agricultural practices have created tens of millions of small artificial water bodies (“farm dams” or “agricultural ponds”) to provide water for domestic livestock worldwide. Among freshwater ecosystems, farm dams have some of the highest greenhouse gas (GHG) emissions per m2 due to fertilizer and manure run‐off boosting methane production – an ext...

The restoration of blue carbon ecosystems, such as mangrove forests, is increasingly used as a management tool to mitigate climate change by removing and sequestering atmospheric carbon in the ground. However, estimates of carbon-offset potential are currently based on data from natural mangrove forests, potentially leading to overestimating the ca...

The widely held assumption that any important scientific information would be available in English underlies the underuse of non-English-language science across disciplines. However, non-English-language science is expected to bring unique and valuable scientific information, especially in disciplines where the evidence is patchy, and for emergent...

Mangroves are known to provide many ecosystem services, however there is little information on their potential role to cap and immobilise toxic levels of total petroleum hydrocarbons (TPH). Using an Australian case study, we investigated the capacity of planted mangroves (Avicennia marina) to immobilise TPH within a small embayment (Stony Creek, Vi...

Introduced species and climate change can have direct impacts on wetland communities, but they can also produce indirect effects such that climate change (i.e., effects of flooding and salinity) can affect native plants by exacerbating or reducing invasion. We assessed the direct and indirect effects of flooding, salinity, and introduced species on...

Shoreline erosion and storm tide inundation increasingly threaten coastal populations, infrastructure and economies. Hard infrastructure, known as gray infrastructure (e.g. concrete seawalls), has commonly been used to protect coastal communities but is expensive to build, maintain, and deteriorates coastal vegetation. Green infrastructure (e.g. re...

Invasive plants often successfully occupy large areas encompassing broad environmental gradients in their invaded range, yet how invader dominance and effects on ecological communities vary across the landscape has rarely been explored. Furthermore, while the impacts of invasion on plant communities are well studied, it is not well understood wheth...

Questions Globally, ecological restoration is required to restore degraded landscapes and to contribute to biodiversity conservation. Ecological theory suggests that manipulating dispersal, abiotic and biotic filters limiting plant re‐establishment will improve restoration outcomes. Here, we manipulated spread depth of soil containing a salvaged so...

Microbial symbionts are gaining attention as crucial drivers of invasive species spread and dominance. To date, much research has quantified the net effects of plant–microbe interactions on the relative success of native and invasive species. However, little is known about how the structure (composition and diversity) of microbial symbionts can dif...

Landscape‐scale restoration requires stakeholder collaboration and recognition of diverse social and ecological motivations to achieve multiple benefits. Yet few landscape restoration projects have set and achieved shared social and ecological goals. Mechanisms to integrate social and ecological motivations will differ in different landscapes. We p...

Previous studies have reported that chemical weed control will be less effective for some weed species under future atmospheric CO2 concentrations. Such reductions in plant sensitivity to herbicides under elevated CO2 may be due to greater biomass accumulation and differences among growth types. However, these studies have been limited to few growt...

Background/Question/Methods Accumulating evidence suggests that restoration projects, especially in hyper-diverse ecosystems, generate novel ecosystems rather than recreating a historical or reference condition. To guide management of novel ecosystems towards a close-to-reference goal, this study sought to understand how to apply environmental filt...

Premise of research: Plants are faced with a challenge across all climates they inhabit—they must transport water to their leaves so that photosynthesis can take place. Although this is simple in concept, it can be achieved by different arrangements of root, stem, and leaf traits. The hydraulic functioning of species across aridity gradients is det...

1. Plants must balance water expenditure from their crown with water supplied through root and stem tissues. Although many different combinations of hydraulic traits could accomplish water balance, we ask whether variation across species in stem hydraulic traits has been concentrated along few, or many, dimensions of trait variation. 2. We measured...

The Zemborzycki Reservoir is located in central-eastern Poland, within the administrative boundaries of Lublin city. This is a dam reservoir, built on the Bystrzyca River. One of the main objectives of its establishment was to ensure for the inhabitants of Lublin a convenient place to spend their free time. According to measurements, at the beginni...
