New research shows a single year of warmer-than-average Arctic temperatures can cause malnutrition in Arctic seals, intensifying risks to Inuit food security and northern ecosystems already under pressure from environmental toxins, warn 51社区黑料 researchers.

The SFU study found Arctic ringed seals are struggling to clear persistent contaminants and banned pesticides from their bodies 鈥� a long鈥憈erm health risk made worse when climate鈥慸riven changes to sea ice and temperatures limit their access to nutrient-rich food.

鈥淩inged seals are a crucial link between invertebrates, fish and apex predators, and they are a cornerstone of northern food systems,鈥� says Tanya Brown, marine mammal ecotoxicologist and senior study author. 鈥淲e鈥檝e found that warmer conditions can change what they feed on, which changes their contaminant exposure, and that can affect their overall health and survival.鈥�
