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 […]
Moss carpets are a common feature in the maritime Antarctic. They provide habitats for a diverse community of organisms, including microbial groups, micro-invertebrates, and micro-arthropods, all of which depend on […]
Since the 1970s, Pine Island Glacier has exhibited thinning, acceleration, and retreat. During the last decade, the ice shelf has undergone major geometric changes, whilst the quantity and temperature of […]
The Eocene–Oligocene transition (EOT), approximately 34 million years ago, represents one of the most profound climate shifts in Earth’s history—a rapid cooling that marked the transition from the warm Eocene […]
Fish are among the most understudied components of the Southern Ocean food web, yet they are critically important to the functioning of Antarctic marine ecosystems (Caccavo et al., 2021; McCormack […]
