Remote sensing can reveal population dynamics of Antarctic penguin colonies. In this study, we analyze emperor penguin (Aptenodytes forsteri) guano stains in remote sensing imagery and discover colony presence predating known records for 18 colonies across Antarctica.

Avian malaria has been a continuous problem in both wild and captive populations of penguins throughout the world. In Japan, where there are over 3000 captive penguins, avian malaria (by Plasmodium spp.) and haemoproteosis (by Haemoproteus spp.) have ...

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean
The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

Using 25–30 cm Umbra synthetic aperture radar (SAR) imagery combined with ground validation of our observations, we introduce a method to track the phenology of emperor penguins during the Antarctic winter. We successfully identified events in the breeding cycle, which were previously impossible to observe during the complete darkness of Antarctic ...

Autonomous fixed‐wing drones operating beyond visual line of sight of the pilot were used to conduct the first aerial, multi‐species baseline reference survey at the sub‐Antarctic island of South Georgia. Long‐term population monitoring in this remote, challenging environment has historically proved difficult, with terrestrial monitoring generally ...

Antibody reactivity to Afmp1p antigen in penguins with probable and confirmed aspergillosis
Penguins under managed care are widely considered to have high susceptibility to infection by Aspergillus spp. Antemortem laboratory diagnostic options vary in sensitivity and specificity, and antibody detection has been problematic in penguin species ...

A Test of the Coase Conjecture Using Prices of Electronic Books
ABSTRACT The Coase Conjecture predicts that a durable‐goods monopolist without commitment will rapidly cut price toward marginal cost. We test this prediction in the electronic‐book market using release‐day prices. To proxy for marginal cost, we use competitive prices of public‐domain electronic books on the same platforms.

Teacher Perceptions of GenAI‐Integrated Digital Storytelling for Refugee‐Background Youth
Abstract Digital storytelling (DST), the composing of 2–3 minute first‐person digital multimodal narratives, integrating photographs, video clips, voice‐over, text, and music related to personal experiences, is arguably one of the most powerful forms of digital multimodal composing (DMC).
