An understanding of risks to biodiversity is needed for planning action slow current rates decline and secure ecosystem services future human use. Although the IUCN Red List criteria provide an effective assessment protocol species, a standard global higher levels currently limited. In 2008, initiated development risk support ecosystems. We present new conceptual model founded on synthesis relevant ecological theories. To model, we review key elements definition introduce concept collapse,...
The state of global freshwater ecosystems is increasingly parlous with water resource development degrading high-conservation wetlands. Rehabilitation challenging because necessary increases in environmental flows have concomitant social impacts, complicated many rivers flow between jurisdictions or countries. Australia’s Murray–Darling Basin a large river basin such problems encapsulated the crisis its Ramsar-listed terminal wetland, Coorong, Lower Lakes and Murray Mouth. Prolonged drought...
The universal adoption of the UN's 2030 Agenda for Sustainable Development and 17 Goals (SDGs) is a strong sign global interest in integrating economic, social, environmental considerations development aspirations UN member states. An ambitious outcome such an integrated perspective substantial improvement public health social wellbeing while safeguarding natural economic systems on which these rely.1Pradyumna A Planetary food systems: insights from SDGs.Lancet Planet Health. 2018; 2:...
Effective ecosystem risk assessment relies on a conceptual understanding of dynamics and the synthesis multiple lines evidence. Risk protocols models integrate limited observational data with threat scenarios, making them valuable tools for monitoring status diagnosing key mechanisms decline to be addressed by management. We applied IUCN Red List Ecosystems criteria quantify collapse Meso-American Reef, unique containing second longest barrier reef in world. collated wide array empirical...
Predicting ecological response to climate change is often limited by a lack of relevant local data from which directly applicable mechanistic models can be developed. This limits predictions qualitative assessments or simplistic rules thumb in data-poor regions, making management the systems difficult. We demonstrate method for developing quantitative ecosystems based on space-for-time substitution, using distant, well-studied across an inherent climatic gradient predict response. Changes...
Abstract We used Argos‐linked Fastloc‐Global Positioning System (Argos‐linked Fastloc‐GPS) satellite tags to investigate how loggerhead sea turtles use neritic foraging habitats at multiple scales. Out of 24 turtles, six individuals more than one site, with all sites being separated by >25 km. These up four sites, remaining each site for a mean 150 days and returning the same minimum 52 later. The other 18 remained in single site. area within was not uniformly, 15 out exhibiting complex...
<title>Abstract</title> Freshwater resources need to simultaneously support environmental and economic outcomes; this is a critical challenge under climate change. Many outcomes have contrasting requirements for water, leading difficult trade-offs which should be supported by integrated assessments. We analysed the impact of change variability on key ecological values agricultural activity in large catchment Australia assessed effect plausible management adaptation options. Under severe...
Abstract Extreme climatic events are linked to an increase in emergent diseases. Such increases depend on the relationships between environmental conditions and host–parasite dynamics. Caddisflies host oomycete Saprolegnia , which has increased prevalence freshwater systems causes mortality caddisflies, most prominently Ulmerochorema rubiconum . We tested how short (12 h) or longer (21 days) heatwaves (22.5°C water temperature) alter U. hatching infection eggs compared no heatwave (i.e.,...
Riparian clearing and the removal of wood from channels have affected many streams in agricultural landscapes. As a result, these often depauperate in-stream loads, therefore decreased habitat complexity lower levels biodiversity. The introduction was investigated as possible rehabilitation technique for streams. Wood re-introduced to eight two separate high-rainfall, intensively grazed regions Victoria, Australia effect on aquatic macroinvertebrate communities measured. addition increased...
Wetland and floodplain ecosystems along many regulated rivers are highly stressed, primarily due to a lack of environmental flows appropriate magnitude, frequency, duration, timing support ecological functions. In the absence increased flows, health river can be enhanced by operation existing new flow‐control infrastructure (weirs regulators) return more natural flow regimes specific areas. However, determining optimal investment strategies over time is complex task several factors including...
Landscape classification and hydrological regionalisation studies are being increasingly used in ecohydrology to aid the management research of aquatic resources. We present a methodology for classifying hydrologic landscapes based on spatial environmental variables by employing non-parametric statistics hybrid image classification. Our approach differed from previous classifications which have required use an priori unit (e.g. catchment) necessarily results loss variability that is known...
Abstract Biotracers are commonly used in food‐web studies to estimate consumer diets. Increasingly, multiple biotracer types combined provide more nuanced pictures of resource use, unravel complex diet mixtures, and improve the discriminatory power mixing models. However, few compare different types, including impact tracer selection choices, methods exist for combining into a single analysis. We processed three (stable isotopes, fatty acids, amino acids) from same samples determine how...
Objectively assessing ecological benefits of competing watering strategies is difficult. We present a framework coupled models to compare scenarios, using the Coorong, estuary for Murray–Darling River system in South Australia, as case study. The links outputs from recent modelling effects climate change on water availability across Basin hydrodynamic model and then an ecosystem-response model. approach has significant advantages, including following: (1) evaluating management actions...
Abstract Globally, there is little information on freshwater (non‐tidal) wetland below ground soil organic carbon (SOC) stocks, sequestration rates and, in particular, their within‐wetland variation. This basic critical for designing programs to sample SOC stocks and identifying areas that sequester large amounts of so they can be managed prevent degradation loss. Here, focusing temperate seasonally inundated wetlands south‐eastern Australia, we compared (via radiometric dating) among...
