Antarctic Thresholds – Ecosystem Resilience and Adaptation” (AnT-ERA), a new SCAR-biology programme
Read more of: Antarctic Thresholds – Ecosystem Resilience and Adaptation” (AnT-ERA), a new SCAR-biology programmeStresses on Antarctic ecosystems result from environmental change, including extreme events, and from (other) human impacts. Consequently, Antarctic habitats are changing, some at a rapid pace while others are relatively […]

Emperors in hiding: When ice-breakers and satellites complement each other in Antarctic exploration
Read more of: Emperors in hiding: When ice-breakers and satellites complement each other in Antarctic explorationEvaluating the demographic trends of marine top predators is critical to understanding the processes involved in the ongoing rapid changes in Antarctic ecosystems. However, the remoteness and logistical complexity of […]

Influence of fasting during moult on the faecal microbiota of penguins
Read more of: Influence of fasting during moult on the faecal microbiota of penguinsMany seabirds including penguins are adapted to long periods of fasting, particularly during parts of the reproductive cycle and during moult. However, the influence of fasting on the gastrointestinal (GI) […]
