The amplitude of Very Low Frequency (VLF) transmissions propagating from transmitter to receiver between the Earth’s surface and the ionospheric D-region is a useful measurement to detect changes in the […]
In a case study using Van Allen Probe B, we investigate chorus wave observations near the western edge of a plasmaspheric plume characterized by steep density gradients. Initially, wave vectors […]
Although many medium-to-large terrestrial vertebrates are still counted by ground or aerial surveys, remote-sensing technologies and image analysis have developed rapidly in recent decades, offering improved accuracy and repeatability, lower […]
A new microcystin-producing mangrove cyanobacterium, Aliinostoc bakau sp. nov., was isolated from a tropical mangrove in Penang, Malaysia, and characterized using combined morphological and phylogenetic approaches. Cultures were established in […]
The extent of grounded ice and buttressing by the Ronne Ice Shelf, which provides resistance to the outflow of ice streams, moderate West Antarctic Ice Sheet stability. During the Last […]
South Georgia is a heavily glaciated sub-Antarctic island in the Southern Ocean. Cumberland Bay is the largest fjord on the island, split into two arms, each with a large marine-terminating […]
Thermospheric density is one of the main sources of uncertainty in the estimation of satellites’ position and velocity in low-Earth orbit. This has negative consequences in several space domains, including […]
We report the first record of the microlepidopteran Plodia interpunctella beyond the South Shetland Islands at the Chilean Yelcho scientific station (64°52′33.1428″ S; 63°35′1.9572″ W), Doumer Island, close to the […]
Incomplete species inventories for Antarctica represent a key challenge for comprehensive ecological research and conservation in the region. Additionally, data required to understand population dynamics, rates of evolution, spatial ranges, […]
Bryum is a moss genus that is widely distributed across the planet. Many of its species are characterized by large phenotypic and morphological plasticity, generating uncertainty in species identification exclusively […]
