Plastic Pollution in the World's Oceans: More than 5 Trillion Plastic Pieces Weighing over 250,000 Tons Afloat at Sea
The total number of plastic particles and their weight floating in the world's oceans is estimated from 24 expeditions across all five sub-tropical gyres, costal Australia, Bay of Bengal and the Mediterranean Sea conducting surface net tows and visual survey transects of large plastic debris.
Monitoring the abundance of plastic debris in the marine environment
Monitoring waste disposal on ships and plastic debris levels in rivers and storm-water runoff is useful because it identifies the main sources of plastic debris entering the sea and can direct mitigation efforts.
Offshore diplomacy, or how seabirds mitigate intra-specific competition: a case study based on GPS tracking of Cape gannets from neighbouring colonies
It is concluded that gannets from these 2 colonies are spatially segregated and experience different foraging conditions, and it is speculated that wind patterns and group feeding could generate such foraging asymmetries.
Diving Birds in Cold Water: Do Archimedes and Boyle Determine Energetic Costs?
The amount of air in the feathers and the amount of subcutaneous fat in aquatic birds are regulated in such a way as to minimize energy expenditure as a function of the temperature of the environment as well as diving and flying rhythms.
Exploitation of mesoscale oceanographic features by grey-headed albatross Thalassarche chrysostoma in the southern Indian Ocean
Breeding grey-headed albatross Thalassarche chrysostoma, tracked from Marion Island (Prince Edward Islands) during November-December 1997 and January-February 1998, showed a strong association with
African endemics span the tree of songbirds (Passeri): molecular systematics of several evolutionary ‘enigmas’
An emerging phylogenetic picture reveals that relationships within Old World families are highly informative regarding the early dispersal and radiation of songbirds out of Gondwana.

A Brief History of Marine Litter Research
This chapter traces the history of marine litter research from anecdotal reports of entanglement and plastic ingestion in the 1960s to the current focus on microplastics and their role in the
