Conserving marine species effectively requires spatially and temporally explicit knowledge of their abundance and distribution for assessing potential impacts (e.g., from fishery bycatch, anthropogenic sound, ship strikes) over different spatial […]
1. Amid increasing anthropogenic pressures on ecosystems, standardised biodiversity monitoring is critical for assessing biodiversity change. Marine hard-bottom habitats, though ubiquitous and biodiverse, present challenges for biodiversity monitoring due to […]
Pumice rafts derived from submarine eruptions can remain afloat for months or even years, traveling thousands of kilometers on ocean currents. These natural phenomena disperse marine organisms and provide important […]
Antarctic sea ice showed a profound, step-wise reduction around 2016-2017, but the scarcity of modern time series means that we know very little about how Southern Ocean biota have responded. […]
As top predators, leopard seals (Hydrurga leptonyx) have a key role in Southern Ocean ecosystems. For example, this species has driven the local collapse of Antarctic fur seals (Arctocephalus gazella) […]
Background: Pelagic seabirds forage over vast areas, and their movements and diet provide valuable insights into environmental conditions that are otherwise difficult to observe. Snow petrels Pagodroma nivea forage largely […]
The surface texture of bird eggshells differs remarkably between species and is thought to play a substantial role in providing physical and microbial protection for the developing embryo. We used […]
The Tibetan Plateau is a high-altitude arid region, where limited in-situ precipitation measurements are available. In this communication, we document a strong precipitation gradient at the southern edge of the […]
Over the Southern Ocean, atmospheric and climate models have large biases in their radiative fluxes, primarily caused by the representation of supercooled liquid and mixed-phase low-level clouds, both at the […]
South Georgia forms one of the most isolated fragments of continental crust on Earth and lies in a remote location in the Southern Ocean. Its geology is dominated by Early […]
This report presents the outcomes of the international workshop “Essential Biodiversity Variables (EBV) Framework for Terrestrial Antarctic and Sub-Antarctic Ecosystems,” held in Cambridge, UK, from 18–20 September 2024. The workshop […]
Diversity, distribution and biogeographical aspects of polar macroalgae must be reassessed as they face contemporary environmental changes. Macroalgae are the basis of the marine food web, efficient carbon sinks, biogenic […]
