Sub-Antarctic fur seals depredate northern rockhopper penguins at Nightingale Island, Tristan da Cunha [PDF]
Polar Biology, 2020 The most plausible hypothesis for declining population trends of some marine top predators at the northern extent of their breeding ranges in the Southern Ocean is that it results from environmental change. Sub-Antarctic fur seals Arctocephalus tropicalis are opportunistic and pelagic foragers that feed on a variety of fish, cephalopods, and ...

Abstract High resolution analyses of a sediment sequence from an in-filled lake on Nightingale Island at 37°S in the South Atlantic have revealed hydrological variations during the last 10 700 cal yr BP, which are linked to shifts in the Southern Hemisphere westerlies and the Meridional Overturning Circulation (MOC) in the Atlantic.

International Oil Spill Conference Proceedings, 2014
ABSTRACT The Tristan da Cunha island group represents the second largest concentration of sea birds in the world. More than 65 percent of the world's endangered Northern Rockhopper penguin population is found here. Nightingale Island holds more than 100,000 pairs of Northern Rockhopper penguins, 20,000 pairs of albatrosses including the ...

Updated 2016 Nightingale island rock lobster assessment [PDF]
, 2016 This paper provides an updated assessment of the rock lobster resource at Nightingale island. This assessment includes updated data from both the commercial fishery and the biomass surveys. The recent (2013-2015) high GLM standardised CPUE values (and biomass survey index values) at the island were not initially anticipated, and suggest that the impact

Freshwater invertebrate fauna of the Tristan da Cunha islands (South Atlantic Ocean), with new records for Inaccessible and Nightingale Islands [PDF]
Transactions of the Royal Society of South Africa, 2007 As part of a multidisciplinary floristic-faunistic study, a three week survey of the invertebrate fauna of Inaccessible Island (South Atlantic Ocean) was carried out in October/November 1989. In addition, one day of collecting was done on Nightingale Island.

Diet of the Tristan rock lobster Jasus tristani following the 2011 soya spill at Nightingale Island [PDF]
, 2017 The spiny lobster Jasus tristani inhabits the Tristan da Cunha Island archipelago in the South Atlantic Ocean 2,400km from the West coast of South Africa. It is commercially exploited across the archipelago and is the main economic source of income for the local government as it accounts for nearly 80% of the local gross domestic product.

Chironomidae from Gough, Nightingale and Tristan da Cunha islands
Zootaxa, 2011The resurrection of trans-oceanic dispersal is the most striking aspect of a major shift in historical biogeography toward a more even balance between vicariance and dispersal explanations. Molecular dating of lineage divergences favors oceanic dispersal over tectonic vicariance as an explanation for disjunct distributions in a wide variety of taxa ...

SummaryInsular species, particularly birds, experience high levels of speciation and endemism. Similarly, island birds experience extreme levels of extinction. Based on a 2012 taxonomic assessment, historically there were four reed-warbler species in the Mariana Islands, the Guam Reed-warblerAcrocephalus luscinia(Guam), the Nightingale Reed ...
