Galway student studies impact of marine litter on wildlife

Marine litter has become a major issue that cannot be ignored, according
to Galway PhD student Heidi Acampora who is researching the effects of
marine litter on the health of the ocean.

Based in GMIT, Ms Acampora carries out her research on sea birds. She
says European regulations such as the Marine Strategy Framework
Directive (MSFD) require countries to monitor marine litter through
animal life and this has proven to be successful in other countries.

In the North Sea, for example, a species of sea bird called Fulmarus
Glacialis (fulmars) are used for monitoring sea litter.

?My research aims to prove if this can be done in Ireland and if not
through fulmars, then which would be the alternative species suitable
for such monitoring,? said Miss Acampora.

?Sea birds are good indicators because they spend an enormous amount of
time at sea, but come to shore to breed, and that is when we can assess
them. Marine litter has become a major issue that cannot be ignored.?

I press my head against the window, searching for land, but only see the blue expanse of the Tasman Sea. Then the plane turns, revealing a crescent-shaped island with steep volcanic peaks and turquoise-tinted coral reef lagoons. I?ve arrived at Lord Howe Island, commonly touted as ?paradise on earth? or ?Australia?s crown jewel.? It lives up to its reputation, too, with its stunning outcrops and a rare coral reef system ? the southernmost coral reef in the world. But I?m not here to lap up the scenery or to partake in normal tourist activities like scuba diving, kayaking or hiking. Instead I?ve come to learn about the flesh-footed shearwater (Puffinus carneipes), the largest ?muttonbird? to breed on Lord Howe Island, and to understand why shearwater chicks wash up (or ?wreck?) on the island?s coastlines every year. I first meet Dr. Jennifer Lavers, a slender, fair-haired Canadian with boundless energy, at a ?Two Hands Project? beach cleanup at Manly Beach in Sydney. As we sift bottle caps, drinking straws and plastic fragments from the hot sand, I ask about her work with flesh-footed shearwaters on Lord Howe Island. These birds are threatened, she tells me, and she believes that plastic ingestion has a lot to do with it. When shearwaters mistake plastic for food, it can lead to starvation or poison them with heavy metal contamination. Fledglings, or chicks, seem particularly susceptible to death by plastic, probably because they can?t cough it up.

(http://www.sciencedirect.com/science/article/pii/S0025326X14005190) Abstract: Many seabirds are impacted by marine debris through its presence in foraging and nesting areas. To determine the extent of this problem, marine debris use in nest material of the brown booby (Sula leucogaster) in the Great Barrier Reef, Australia, was investigated. Nine cays were examined using beach and nest surveys. On average, four marine debris items were found per nest (n = 96) with 58.3% of surveyed nests containing marine debris. The source of marine debris in nests and transects were primarily oceanic. Hard plastic items dominated both nest (56.8%) and surveyed beaches (72.8%), however only two item types were significantly correlated between these surveys. Nest surveys indicated higher levels of black and green items compared to beach transects. This selectivity for colours and items suggest these nests are not good indicators of environmental loads. This is the first study to examine S. leucogaster nests for marine debris in this location. Keywords: Seabird; Plastic pollution; Threat; Beach survey; Environmental indicator

(http://www.sciencedirect.com/science/article/pii/S0025326X14005190) Abstract: Many seabirds are impacted by marine debris through its presence in foraging and nesting areas. To determine the extent of this problem, marine debris use in nest material of the brown booby (Sula leucogaster) in the Great Barrier Reef, Australia, was investigated. Nine cays were examined using beach and nest surveys. On average, four marine debris items were found per nest (n = 96) with 58.3% of surveyed nests containing marine debris. The source of marine debris in nests and transects were primarily oceanic. Hard plastic items dominated both nest (56.8%) and surveyed beaches (72.8%), however only two item types were significantly correlated between these surveys. Nest surveys indicated higher levels of black and green items compared to beach transects. This selectivity for colours and items suggest these nests are not good indicators of environmental loads.

(http://www.sciencedirect.com/science/article/pii/S0025326X14005402) Abstract: Plastic pollution is widespread in the marine environment, and plastic ingestion by seabirds is now widely reported for dozens of species. Beached Northern Fulmars, Great Shearwaters, Sooty Shearwaters and Cory?s Shearwaters are found on Sable Island, Nova Scotia, Canada regularly, and they can be used to assess plastic pollution. All species except Cory?s Shearwaters contained plastic debris in their gastrointestinal tracts. Northern Fulmars, Sooty Shearwaters and Great Shearwaters all showed high prevalence of plastic ingestion (>72%), with Northern Fulmars having the highest number and mass of plastics among the species examined. There was no difference in plastic ingestion between sexes or age classes. In all species user plastics made up the majority of the pieces found, with industrial pellets representing only a small proportion in the samples. Sable Island could be an important monitoring site for plastic pollution in Atlantic Canada.
