Wetlands globally have and continue to undergo modification from anthropogenic natural environmental factors. To bridge this gap, study utilised a GIS-based approach quantify the areal extent of human footprint disturbances wetlands over time. This attributed wetland disturbance by class, type sector during two notable transitions, 2000 2010 2018, in oil sands region (OSR) northern Alberta, Canada. The area was calculated using physical dataset intersected with Alberta Merged Wetland Inventory. Results indicate that 3284 km2 (2616 between 2010, 668 2018) undergone OSR. Examination industrial 2018 indicates gas forestry sectors are greatest sources (402 179 km2, respectively). Monetary assessment ecosystem services per year results minimum yearly loss USD 30.05 million for peatlands 197.86 marshes swamps (2007). analysis is valuable quantifying impact on wetlands, which critical ensuring sustainable development wetland-rich areas.

Altered body condition and diminished growth in wildlife the Alberta Oil Sands Region (AOSR) are prompting investigations into impact of oil sands industrial activity on region. Chemical constituents from bitumen-influenced waters, including process-affected water (OSPW), can disrupt endocrine signaling, leading to aberrant lipid accumulation altered glycemic control mammals. This study aimed investigate effects naphthenic acid fraction components (NAFCs), derived OSPW, energy homeostasis using McA-RH7777 rat hepatocyte model. Cells were exposed NAFCs at nominal concentrations 0, 0.73, 14.7, 73.4 mg/L for 24 48 h. We assessed gene expression related glucose metabolism measured triglyceride accumulation, glucose, fatty uptake. NAFC exposure (14.7 mg/L) reduced levels uptake increased beta-oxidation genes, suggesting a metabolic switch oxidation. substrate availability signifies shift cellular dynamics, potentially linked mitochondrial function. To this, we conducted adenosine triphosphate (ATP), membrane potential, terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) assays measure ATP levels, apoptosis, respectively. At both time points, resulted induced hyperpolarization, apoptosis. These results suggest that efficiency is compromised, necessitating adaptations maintain homeostasis. Given cells exhibit flexibility allows them dynamically respond changes availability, further demonstrated kynurenine–tryptophan ratio (KTR) serves as marker under these stress conditions. work provides mechanistic framework understanding how bitumen-derived organic contaminants may function living AOSR. findings support use molecular markers like KTR evaluate sub-lethal environmental health monitoring.

The braiding of Indigenous knowledge systems and Western-based sciences offers insights into ecology has emerged as a way to help address complex environmental issues. We reviewed the publicly available ecological research involving support collaborative work in Alberta oil sands region Canada. conducted systematic review, coding for 78 questions six categories: (1) literature search bibliographic information; (2) themes; (3) study setting design; (4) systems; (5) power relationships, colonization, ethical considerations research; (6) benefits challenges braiding. identified articles that braided knowledge, with those focusing on management monitoring impacts industrial activity northern Alberta. Researchers used broad range approaches gather scientific data multiple (e.g., asymmetries power, resource availability, funding) research. Our findings show more is needed foster, promote, disseminate interdisciplinary Additional also required community needs related assessment impact reclamation, well understanding threats across region.

Just transition policies are widely viewed as one of the most effective mechanisms for compensating and building support decarbonization in fossil fuel communities. However, early empirical work suggests that many coal-producing regions remain opposed to even when just proposed or implemented. In this study, I add nuance existing accounts by analyzing data from 18 interviews with oil gas workers community members Canadian Oil Sands, world's third-largest reserve. show how those living working Sands skeptical renewable energy, optimistic about long-term viability fuels, strongly oppose proposal a transition. These responses patterned feelings fear, exclusion, resentment towards motives actors driving decarbonization, which argue demonstrates threatened sense ontological security.

Abstract This essay examines the role of data practices in making and refuting settler colonial environmental science. Investigating epistemic contestation surrounding contamination produced by oil industry Alberta, Canada, I discuss an alternative approach to toxicology: a community‐based monitoring programme that uses ‘three‐track’ methodology present three distinct forms. Using this method, First Nations communities engaged strategic translation, balancing their aim rendering Traditional Knowledge community needs legible policy‐makers against desire protect from being assimilated into dominant paradigm. argue, enacts form resistance era relentless datafication: making‐things‐into‐data can reflect exercise agency rather than submission external pressure. In way, three‐track models how marginalized leverage data's productive capacities for own ends produce scientific knowledge on terms.

Landing Community (ALMC) members have traditional local wildlife and climatic conditions region has seen intense oil gas-related industrial activity over last 50 years. Informed by multiple evidence-based approach to CBM, ALMC’s combined hunting, fishing, trapping, plant gathering activities with photomapping methods. By taking geo-referenced photos their environmental observations, which they shared other project participants during regular meetings, holders connected changes such as resource scarcity or species abundance broader ecological processes including climate change.
