Gaining insight into population changes of species in remote areas of the world poses challenges, often resulting in opportunistic observations (convenience sampling) that limit scientific inference. Remote sensing resources, typically […]
Human-induced global climate change and other anthropogenic stressors are fundamentally altering our oceans. Understanding the ecological and societal implications of these changes is critical for developing mitigation strategies and conservation […]
Semiautonomous imaging technologies are increasingly being used to characterize zooplankton communities, albeit with limited comparison to traditional techniques. Here we compared copepod community compositions obtained using a FlowCam Macro with […]
Microplastics (MP) are a relevant stressor in Arctic marine ecosystems. Their small size and ubiquity make them readily ingestible by zooplankton, placing copepods at the entry point of MP into […]
Retreating glaciers are rapidly transforming fjord ecosystems along the Western Antarctic Peninsula (WAP), yet the trophic responses of benthic fauna remain poorly understood. We analysed δ13C, δ15N, δ34S, and C:N […]
The environmental heterogeneity of coastal lagoons makes their classification challenging. Historically, lagoons have been characterised unilaterally according to their geomorphological, hydrological, saline or biotic features. While these characteristics are important, […]
Accurately representing the snow depth (SND) distribution on sea ice is essential for sea ice thickness (SIT) retrievals, ecological studies, and climate modelling. Using co-located SND and SIT measurements from […]
Density is a major determinant of population dynamics, with high densities exacerbating intraspecific competition and disease transmission while low densities increase predation risk. To investigate spatiotemporal density patterns and predator–prey […]
Increasing human activity and climate change in Antarctica may increase the rates of non-native species introduction and establishment, resulting in potentially irreversible changes in marine and terrestrial ecological communities. The […]
Invasive non-native species are amongst the most serious threats to biodiversity at local and global scales. Due to their geographical remoteness, extreme conditions and lower levels of human activity, the […]
Antarctic sea ice extent began declining in 2015, reaching its minimum in the post-1970s observational era in 2023.To diagnose the drivers of this decline, we analyze an observationally constrained sea […]
The increase in shipping in the Canadian Arctic has significant impacts on Inuit coastal communities and their traditional way of life. Examples include the risk of chemical spills, underwater noise […]
