This paper highlights a growing concern related to threats posed to marine wildlife from microplastics and fragmented debris, the need for data at scales relevant to management, and the urgent need to develop interdisciplinary research and management partnerships.
We identified areas predicted to support multispecies seabird aggregations in the Timor Sea based on at‐sea survey observations of 21 seabird species from 2000–2013 and oceanographic variables. The model demonstrated 3 areas of high seabird richness that varied little between seasons.
From 14–20 November 2013, the number of Greater Crested Terns breeding adjacent to a Brown Booby colony was reduced from 128 adults attending the colony to 59 adults. During this time, two juvenile Brown Boobies were observed depredating the eggs and ingesting prey regurgitated by Greater Crested Terns
We measured stable isotope values in Australian Flesh‐footed Shearwaters. During 1936–2011, the species more than doubled their trophic niche and dropped an entire trophic level in 75 years – the largest change in δ15N yet reported in any marine bird, suggesting a relatively rapid shift in the composition of the Indian Ocean food web.
We examined the physiological responses of Streaked Shearwater chicks to possible radiation exposure during the 2011 breeding season, four to seven months after the Fukushima nuclear accident. Fledglings from Mikura Island (nearest Fukushima) displayed significantly reduced vitamin A levels.
We sampled breast feathers and stomach contents from Flesh-footed Shearwater fledglings. Birds with high levels of ingested plastic exhibited reduced body condition and increased contaminant load (p < 0.05). More than 60% of fledglings exceed international targets for plastic ingestion by seabirds.
