Part II. The terrestrial botany of the Tristan da Cunha Islands
Philosophical Transactions of the Royal Society of London Series B, Biological Sciences, 1965Abstract The islands of Tristan da Cunha, Inaccessible, Nightingale and Gough are alike in their climate and physiography, and also in their plant and animal life. They form a single biogeographical province, and the botany of all four islands will be dealt with here.

Increase of sub-Antarctic fur seals at the Tristan da Cunha Islands
Polar Biology, 2018Sub-Antarctic fur seal, Arctocephalus tropicalis, pups were counted on some of the beaches on all four Tristan da Cunha (TdC) islands, in January 2017, to determine the status of the population, in the face of climate change that is magnified in polar regions. Compared to counts done 40 years earlier on Gough, the breeding population increased markedly

Asthma amongst Tristan da Cunha islanders
Clinical & Experimental Allergy, 1974SummaryThe incidence of asthma amongst Tristan da Cunha islanders was recorded over a period of 16 months. Thirty‐two per cent of the islanders gave a history of asthma, and 22% had one or more attacks during the survey period. Three‐quarters of the affected islanders had mild asthma.

Rats and prions at Tristan da Cunha Island
Ostrich, 2020Tristan da Cunha is a 96 km2 volcanic island in the South Atlantic Ocean. Black Rats Rattus rattus reached the island from a shipwreck in 1882 and their depredation of seabirds’ eggs and chicks are likely partly responsible for the much lower densities of burrow-nesting petrels, compared with adjacent rodent-free islands in the archipelago.

An investigation of asthma among the Tristan da Cunha islanders
British Journal of Diseases of the Chest, 1964Summary Asthma occurs very commonly amongst the Tristan da Cunha islanders. Although allergic causes were found in most asthmatics, other allergic diseases were uncommon. The high incidence of asthma is likely to be due to genetic factors in a highly inbred community, the hereditary factor being one of heightened reactivity of the bronchi rather than

Variation atDENND1Band Asthma on the Island of Tristan da Cunha
Twin Research and Human Genetics, 2019AbstractA high prevalence of asthma has been documented among the inhabitants of Tristan da Cunha, an isolated island in the South Atlantic. The population derives from just 28 founders. We performed lung function testing, including methacholine inhalation challenge, allergen skin prick testing, and collected DNA from essentially all of the current ...

The founding mitochondrial DNA lineages of Tristan da Cunha Islanders
American Journal of Physical Anthropology, 1997Genealogical histories show that the inhabitants of Tristan da Cunha are derived from a known number of founders. Using the transmission of mitochondrial DNA (mtDNA) from mother to offspring pairs, we traced the mtDNA types found in 161 extant individuals to five female founders. Although the historical data claimed that two pairs of sisters were among
