The Antarctic Peninsula has experienced considerable anthropogenic warming in recent decades. While cryospheric responses are well defined, the responses of moss-dominated terrestrial ecosystems have not been quantified. Analysis of Landsat archives (1986–2021)…
Antarctica, Earth's least understood and most remote continent, is threatened by human disturbances and climate-related changes, underscoring the imperative for biodiversity inventories to inform conservation. Antarctic ecosystems support unique species and genetic diversity…
There is growing interest from research and conservation groups in the potential for using small unoccupied aerial vehicles (UAVs; <2 kg) to conduct wildlife surveys because they are affordable, easy to use, readily available and reliable. However, limitations such as short flight endurance…
Aerial surveys are frequently used to estimate the abundance of marine mammals, but their accuracy is dependent upon obtaining a measure of the avail?ability of animals to visual detection.
There are many advantages to transitioning from conducting marine wildlife surveys via human observers onboard light-aircraft, to capturing aerial imagery using drones. However, it is important to maintain the validity of long-term data series whilst transitioning from observer to imagery surveys.
The mid- to high-latitudes of the Southern Hemisphere are dominated by the westerly winds. These are important because changes in their strength determine precipitation and temperature regimes. However, little is known about their past strength, or spatial and temporal variability.
The sub-Antarctic region between 45-60°S is primarily ocean. However, there are a few small isolated islands, most of which are currently facing the combined pressures of climate change and introduced species.
The sub-Antarctic region between 45-60 °S is primarily ocean. However, there are a few small isolated islands, most of which are currently facing the combined pressures of climate change and introduced species.
Sub-Antarctic islands are the only landmasses between Antarctica and South America, Africa and Australia where terrestrial climate and ecosystem records are available, making them crucial locations for linking southern mid and high latitude regions. However…
The Antarctic climate system varies on timescales from orbital, through millennial to sub-annual, and is closely coupled to other parts of the global climate system.
