“…2). White-chinned petrels have only 0.9% incidence of debris in Australasia compared to 63.1% off Brazil, a region with much higher rates of plastic pollution 20 . Other studies also highlight environmental exposure to debris as an important factor in incidence of debris ingestion 21 .…”

Procellariiform seabirds are both the most threatened bird group globally, and the group with the highest incidence of marine debris ingestion. We examined the incidence and ecological factors associated with marine debris ingestion in Procellariiformes by examining seabirds collected at a global seabird hotspot, the Australasian - Southern Ocean boundary. We examined marine debris ingestion trends in 1734 individuals of 51 Procellariform species, finding significant variation in the incidence of marine debris abundance among species. Variation in the incidence of marine debris ingestion between species was influenced by the taxonomy, foraging ecology, diet, and foraging range overlaps with oceanic regions polluted with marine debris. Among the ecological drivers of marine debris ingestion variability in Procellariiformes, we demonstrate that the combination of taxonomy, foraging method, diet, and exposure to marine debris are the most important determinants of incidence of ingestion. We use these results to develop a global forecast for Procellariiform taxa at the risk of highest incidence of marine debris ingestion. We find seabirds that forage at the surface; especially by surface seizing, diving and filtering, those with a crustacean dominant diet, and those that forage in or near marine debris hotspots are at highest risk of debris ingestion. We predict that family with the highest risk are the storm petrels (Hydrobatidae and Oceanitidae). We demonstrate that the greater the exposure of high-risk groups to marine debris while foraging, the greater the incidence and number of marine debris items will be ingested.

“…When comparing modelling results with empirical data, a temporal increase in marine litter amounts was demonstrated in a limited number of studies for remote parts of the ocean, such as remote islands, the Antarctic [3], the Indian Ocean [10] and the South Atlantic [37], for plastic ingested by south Atlantic petrels [35], and in specific oceanographic features, including converging currents above the Arctic circle [41]. Interestingly, since the 1950s baseline, floating microplastics at sea increased exponentially each decade until the 2000s [42].…”

Are litter, plastic and microplastic quantities increasing in the ocean?

et al. 2021

Whilst both plastic production and inputs at sea have increased since the 1950s, several modelling studies predict a further increase in the coming years in these respective quantities. We compiled scientific literature on trends in marine litter, consisting largely of plastic and microplastics in the ocean, understanding that monitoring programs or assessments for these aspects are varied, frequently focusing on limited components of the marine environment in different locations, and covering a wide spectrum of marine litter types, with limited standardization. Here we discuss how trends in the amounts of litter in the marine environment can be compared with the information provided by models. Increasing amounts of plastic are found in some regions, especially in remote areas, but many repeated surveys and monitoring efforts have failed to demonstrate any consistent real temporal trend. An observed steady state situation of plastic quantities in many marine compartments and the fate and transport of plastic in the marine environment remain areas for much needed further research.

A presença de resíduos antropogênicos em águas oceânicas e sua ingestão por aves marinhas tem sido alvo de um crescente número de estudos. Os Procellariiformes são particularmente suscetíveis à ingestão de plástico, uma vez que se alimentam preferencialmente de pequenas presas na superfície da água, onde os plásticos tendem a flutuar e se acumular. Após revisão bibliográfica e aplicação prática de técnicas em campo e laboratório, apresentamos um protocolo padronizado de amostragem para a avaliação da ingestão de plásticos por Procellariiformes que inclui recomendações para opções de tipos e fontes de amostras, além de adaptações à coleta para atender a diversos objetivos de pesquisa. As amostras podem ser coletadas de animais mortos oriundos da captura incidental em atividades de pesca; encalhes de praia; aves mortas nas colônias ou centros de reabilitação; animais vivos em colônias ou centros de reabilitação; ou amostragem não invasiva por meio das fezes, bolos alimentares e ovos não eclodidos. Além disso, sugerimos tipos de análises possíveis, materiais necessários e rotinas de limpeza para evitar a contaminação durante a coleta e processamento. O uso de protocolos padronizados aumenta a consistência, comparabilidade e a reprodutibilidade, permitindo comparações entre estudos em escalas temporais e espaciais diferenciadas.
