Stranding data are critical for monitoring threats to sea turtles. By analyzing four decades of green turtle (Chelonia mydas) strandings from the Main Hawaiian Islands, we elucidate temporal and spatial trends. In Hawai'i, fibropapillomatosis (FP) has been the dominant threat for stranded turtles since records began in 1982. In the last decade (201...

The IUCN Red List of Threatened Species is essential for practical and theoretical efforts to protect biodiversity. However, species classified as “Data Deficient” (DD) regularly mislead practitioners due to their uncertain extinction risk. Here we present machine learning-derived probabilities of being threatened by extinction for 7699 DD species,...

Marine animals have been known to interact with and become entangled in plastic debris for decades. Despite increasing annual input volumes of plastic waste to the natural environment and the threat this constitutes to marine biodiversity, impacts of mismanaged plastic waste generally remain unquantified in environmental impact assessments. In this...
